1.0 USER MANUAL

1.1 INTRODUCTION Congratulations for choosing QPE-C panel (with MC4 electronic logic) for managing your genset. Later on, you will appreciate the great flexibility of use and high performance allowed by the high technology of the electronic module MC4. This is a microprocessor based electronic module that manages all types of gensets, both traditional ones and with CAN-BUS commands. It is set to communicate over MOD-BUS with various devices such as main-genset transfer switching cabinets with commutation, pc, remote touch-screen panels, alarm repeating modules etc. Through a GSM module (integrated on-demand) you can manage and totally control your genset from miles away. MC4 is equipped with fully digital instrumentation that allows you to monitor all the parameters of the engine, generator, and related accessories. The USER MANUAL aims to provide a clear and simple guide in order to consent a quick, complete and safe use of the genset.

1.2 AIM This manual provides all the necessary information regarding the use of the genset with QPE-C panel:

1. Knowing the operating basics of the panel; 2. Interpreting the indications of the electronic panel; 3. Setting the electronic card in the different service require ments; 4. Making the minimum necessary checks to ensure the smooth funct ioning of the genset.

Any technical or adjustment elements are not discussed because they are managed by the manafacturer during creation of the machine.

1.3 OPERATING BASICS 1.3.1 HOW THE QPE-C PANEL WORKS WITH THE GENSET. The QPE-C panel can be matched with all the generators with power range from 10 to 2500 kva, with operating voltages from 220 to 460 volts, 50 or 60Hz, with traditional engines or with Can-bus control ones. In Fig. 1 is shown the standard components of the plant that is made of: a generating set GE, control panel QPE-C, a machine switch INT. (which varies according to the power of the genset).

Fig. 1



10/01/2010 ITA Pagina 6 di 72

The QPE-C panel monitors and detects all the parameters of both the engine and the generator. It has a three-position key that sets the type of plant’s operating mode. With key on position 0 the panel is switched off, the genset is off. With key on Manual the start-up is decided by the user by pressing the start button. With key on Automatic , depending on the operating mode, the start-up could be through external contact, lack of electricity from the relative mains, command in MOD-BUS, from the communication network via sms, etc.. During the functioning all the electrical and mechanical parameters of the genset are displayed and all the protections are enabled, including overload, short-circuit and earth fault if set. If an anomaly happens the INT switch opens through the opening coil and it disconnects the load, then after the cooling phase the engine stops. In combination with an ATS (Automatic Transfer Switch) with or without mains sensor, it becomes a complete system for the mains failure, (as per Figure 2). The QPE-C panel is able to autonomously manage even the commutation mains-genset. Fig.2

GE Generating set (generator + engine)

CARICO Preferential load CG Genset counter

1.3.2 ADJUSTABLE OPERATING MODES The QPE-C panel, in order to cover all needs, can be set in three distinct operating modes: 1 Manual mode 2 Automatic mode 3 Mod-bus mode The setting of these three modes is done by inserting three micro-switches (dip 1-2-3) on the motherboard, see page 30. MANUAL MODE. In Manual mode, the panel can be used in two ways, depending on the position of the board key. With key on Manual, the genset start-up occurs exclusively by pressing the start button by the user. With key on Automatic, the start-up occurs through an external command (potential free contact) that if Active, it launches the automatic process of start-up and the possible management of inserting load. So, the consent of start-up can be given by external devices such as floats, pressure switches, thermostats, relay voltmeters etc. AUTOMATIC MODE



10/01/2010 ITA Pagina 7 di 72

In Automatic mode, and with key on Automatic, the panel is able to operate as an emergency system to the mains. It fully manages both the start-up of the genset and the complete management of mains-genset commutation in the separated ATS. Suppose that we are in the situation represented in Figure 2, where the mains is within normal values: the CR counter is closed and the use is powered by the mains. The QPE-C monitors the mains and in case of any anomaly or the lowering or lack of a phase or because of asymmetry of the phases themselves, it acts as follows:

1. It commands the opening of CR mains counter; 2. It enables the start-up of the genset and once it has reached the right functioning level, it commands

the closing of the CG counter, powering the use through the GE generator; N.B.: During the functioning, the engine and generator are monitored to determine if any abnormalities occur. If this is the case, these abnormalities would cause the immediate arrest of the genset with consequent storage and visualization onto the display, showing the cause of the alarm (e.g. low oil pressure, overload, etc.).

3. When the mains come back to normal values, after a set delay the QPE-C opens the CG genset counter and after one second, closes the CR counter. In this way it re-powers the use with the mains.

4. The genset keeps running for at least one minute to burn off the excessive heat and at the end of cooling time, it stops automatically.

If the user has its own ATS with an independent management of commutation, then he can only use the mains sensor of QPE-C panel to handle only the start-up when the mains fail. MOD-BUS MODE. In this mode, if the key is on Manual position, the genset start-up occurs by pressing the start button. On the contrary, if the key is on Automatic position, the start input can be sent through a Mod-Bus message, which is sent by a management control unit or by an external plc.

10/01/2010 ITA Pagina 9 di 72

2. With the keyed selector on ZERO, the genset is totally disabled, power consumptions on the power battery are excluded. If the key is turned to ZERO position while the genset is running, the panel will not switch off immediately, but it will first start the process of shutdown and when the engine cooling process is finished, the panel will shut down entirely. The timing of the shutdown procedure is displayed through an animated hourglass on the graphic display. 3. When the key is on MAN, the START and STOP buttons are enabled. Therefore, it is up to the user to decide the start-up of the genset.

1.5.2 DESCRIPTION OF SINGLE BUTTONS AND WARNING LIGHT F UNCTIONS.

1. SIREN MUTE BUTTON (T1) When it is pressed, this button silences the alarm buzzer, the corresponding red LED indicates the presence of a failure. The reset of the alarm occurs by pressing the reset button indicated here below. In Setup mode, pressing the button allows you to leave the various Setup menu.

2. FUEL PUMP ACTIVATION BUTTON (T2)

If it is pressed with key on Manual, it activates the pump for refuelling the daily tank from an external tank, if it is pressed again, it switches it off. The pump stops automatically when it reaches the maximum level. The corresponding green LED lights up every time the pump starts running. With key on Automatic, the button is disabled because the activation of the fuel pump takes place automatically according to the level of the tank.

In setup mode, the pressure of the button needs to increase the values of the parameters visualized on the display. 3 GLOWPLUGS OR ENGINE PRE-HEATER ACTIVATION BUTTON (T3)

The warning light corresponding with this button has two distinct functions, depending on the type of setting. If the “glowplugs” function is enabled in the card, the light will turn on before the start-up, indicating the insertion of glowplugs for pre-scheduled time. If the “engine pre-heater” function is enabled on the card, the light turns on every time the resistance that keeps the engine water at the correct temperature is

activated. The button is active only in manual mode and only in "glowplugs" mode. If pressed, it allows the reintegration of glowplugs. In Setup mode, the pressure of the button needs to decrease the values of the parameters visualized on the display. 4 RESET-ENTER BUTTON (T4)

If pressed during normal functioning, it erases the alarms states and restores the functions. In setup mode, it confirms the selection or stores the data.

5 STOP BUTTON (T7) This button is always enabled both in manual and automatic. It stops the machine when pressed. The red LED corresponding with this button indicates that the shutdown phase is in progress.

6 START BUTTON (T8)



10/01/2010 ITA Pagina 10 di 72

This button in enabled only when the change-over switch is on MAN position. The control is manual, it is therefore necessary to hold the start button until the start-up is completed. The green LED corresponding with this button indicates that the start-up command is in progress.

7 GENSET TEST BUTTON (T9)

The button in active only if the key is on Automatic and it enables two different functions: “Instantaneous automatic test” is obtained by pressing the button for more than 3 seconds. The genset starts, the machine runs freely for the scheduled time and then it stops automatically. The corresponding green led flashes,

indicating that it has activated the function. “Programmed automatic test” is activated by quickly pressing the button. This function allows the inner timer to activate, in order to test the genset at pre-scheduled times and dates. If this function is activated, the corresponding green LED remains turned on with fixed light. The setup test scheduling is carried out in Setup menu described later, see page 47.

8 DISPLAY MODE BUTTONS (T5-T6)

These buttons allow you to navigate around the display pages. In setup mode, they allow you to access the different menus.

This page displays the alarms transmitted via CAN-BUS from the engine electrical box. In case of failure, the alarm codes are displayed to identify the type of failure. This system constitutes a diagnostics on the entire electrical system of the machine, even if the engine stopped, the efficiency of sensors and wiring is checked. To interpret the code you should check the corresponding engine’s manual (N.B.: each model, even if it is from the same manufacturer has its own manual to consult). The engine manual lists the type of alarm and the remedy to be made to the machine. For ex.: I own a genset with engine Volvo TAD1242GE and the

display shows CAN 184 writing. By consulting the manual, this anomaly code corresponds to "fault on the oil temperature sensor”, so the connections of the sensor or the sensor itself have to be checked

This page appears after switching on the panel only with card set to operate in mode 2. It displays the status of the genset-mains commutation and the three mains voltages. The ON-OFF writings on top of the mains and genset symbols indicate the actual presence of mains or genset voltage within the limits. The CR and CG contacts symbols indicate the status of contacts for the management of remote commutation. The display shows the three mains voltages. Even if in only one phase the voltage goes out of minimum and maximum voltage set bounds, the genset starts up

automatically anyway. Page 15

This page appears automatically only in mode 2, and only when the genset is running. It displays the status of commutation and shows the genset voltage. The ON-OFF writings on top of the mains and genset symbols indicate the actual presence of mains or genset voltage within the limits. The CR and CG contacts symbols indicate the status of contacts for the management of remote commutation

1.6 COMMANDS AND FUNCTIONING IN THE THREE MODES 1.6.1 SETUP OF OPERATING MODES The QPE-C panel can be set in three distinct operating modes: 1 Manual mode 2 Automatic mode 3 Mod-bus mode The setting of these three modes is made through the insertion of 3 micro-switches (dip 1-2-3) on the motherboard, see page 30. .

1 Manual Mode 2 Automatic Mode 3 Mod-bus Mode

The insertion of these dips has to be done with key in OFF position. 1.6.2 MODE 1 MANUAL With key in OFF position , the electrical circuits are no longer powered and the genset is not powered. (It is used for maintenance stages) . With key in MAN position the genset manual controls are enabled through the START and STOP buttons. Once the genset is started-up, wait for it to reach the operating speed before closing the switch to power the load. When it is shutting down, as first operation the load has to be disconnected by opening the switch and after approximately one minute the genset has to be stopped. While running, the generator and motor are continuously monitored and any possible abnormality is immediately displayed on the screen (for example: fuel reserve, water level, overload, minimum voltage, etc.) and the relative arrest cycle is activated; if it is enabled also the instantaneous opening of the switch. With key in AUT position , the start-up is determined by an external command that starts the automated process of ignition. Once the engine has reached its full operating speed, then the consent to the closing of the load is given. While running, the generator and motor are continuously monitored, any abnormality is immediately displayed on the screen and the relative cycle arrest is activated, as well as the disabling of load and the subsequent cooling of the engine. The external enabled controls are as follows: 1. Available potential free contact for thermostats, pressure switches, floats, timers, selectors, etc. connected to the terminals 44-45 of motherboard J12 connector. 2. SMS command if inside the card the modem is mounted. 3. Start-up at scheduled intervals by a programmer watch integrated in the card. 1.6.3 MODE 2 AUTOMATIC



10/01/2010 ITA Pagina 18 di 72

The automatic mode comes as an application of the genset in case of public mains failure, so the panel is asked to manage both the automatic start-up of the genset whenever the public mains fails, and the mains-genset commutation through two potential free contacts that drive some power change-over switches (remote ATS). With key in OFF position , the electrical circuits are no longer powered and the genset is not powered. (It is used for maintenance stages) . The management of the mains line closing remains guaranteed even if the battery is disconnected.

WARNING! The management of the mains line closing is always guaranteed and always takes priority. No matter in which position the key has been put, or with the panel dis connected from the battery, the management contact mains-line remains closed.

With key in MAN position , the genset manual controls are enabled. It is possible to start it up through the START and STOP buttons, but the load will remain powered by the public mains. Therefore the maintainer can try the machine without creating power gaps on the usage powered by the mains. While the genset is running, in case there is a mains failure, the load commutation on the genset will start immediately. With key in AUT position , the start-up of genset is done automatically when the referenced mains-line goes beyond the limits of minimum and maximum set voltage, (the measure is carried out on each single phase). After the genset has started and the voltage and frequency have stabilized, the panel commands the insertion of the load. While running, the generator and engine are continuously monitored, any abnormality is immediately displayed on the screen and the relative cycle arrest is activated, as well as the disabling of the load and the subsequent cooling of the engine. When the mains come back after a programmable delay, the load is re-commutated on the mains and after the expected cooling time the genset stops automatically. 1.6.4 MODE 3 MOD – BUS Prologue The MOD-BUS is an industrial communication protocol that allows the connection of multiple devices (slave) to a concentrator device (master) which, in turn, allows you to view and drive all the connected devices. The connection is on port RS485, the standard communication format is RTU (binary), and via a two-wired cable you can make a teleprocessing up to 1Km away. With key in OFF position , the electrical circuits and the genset are no longer powered. (It is used for maintenance stages) . With the key in MAN position, the operating is identical to the manual mode 1. With key in AUT position , the start-up is determined by an external command sent over the MOD-BUS line, which initiates the automatic process of ignition. With the engine at full operating speed, the consent to close the load is given via a return message over the MOD –BUS line. This mode allows the direct interfacing of QPE-C panel with external PLCs, computers, or with other types of devices that use the MOD-BUS as a communication system. The MOD-BUS connection, via a two-wired shielded cable, allows to bring the start-up commands to a remote distance and the acquisition of all the alarms and measures of the genset.

1.7 SETUP LANGUAGE The MC4 control card provides the setup of 5 default languages through micro-switches placed on the DIP1 motherboard. In this way all the descriptive and warning messages that appear on the display will be easily understood by all users. Italian English Spanish French Programmable The setup of micro-switches can be made at any time, both with the card switched off and switched on. N.B. The translation of the programming menus is available only in Italian and English.

1.8 OTHER FUNCTIONS The MC4 is set up for special functions listed below: 1.8.1 EMERGENCY STOP The activation of the emergency button is displayed on the screen with the following words: “ EMERGENCY STOP ACTIVATED”

The emergency stop is made via a mushroom-shaped button called PAE with rotating unlocking system. It is normally mounted on the canopy in an easily accessible position. In all the operating modes, the pressure of the PAE button causes an immediate engine shutdown and if set, the immediate opening of the machine switch. The activation of emergency in mode 2 does not cause the opening of the closing mains command, therefore the public mains will continue to power the load. The activation of the emergency will stop the genset, therefore in order to restore the normal operating mode unlock the PAE emergency button by turning it and afterwards resetting the MC4 card through the RESET button. The MC4 card provides a connection to a second emergency button that the user can mount on the most appropriate place, for example onto the electric cabin entrance so that in case of fire, firemen can inhibit the functioning of the genset. In order not to confuse the two commands, the insertion of the remote emergency button is displayed with the following different wording: “ REMOTE EMERGENCY ACTIVATED” 1.8.2 LOCKED GENSET The activation of the lock control is displayed on the screen with the following message: “ REMOTE LOCK ”

The lock function is mainly used when the genset works at times or conditions set by an external control, such as floats or programmer watches. For example in a town where the emergency is not required at night, you can inhibit the genset through a watch. During the lock time, if the mains fail the genset does not intervene. By opening the lock contact everything starts to function normally again. The report of lock status is shown on display at page 1.



10/01/2010 ITA Pagina 20 di 72

1.8.3 REMOTE TESTING The activation of remote testing command is displayed on the screen with the following message “START COMMAND FROM EXTERNAL TEST” The test function allows the start-up of the genset through an external contact when you are in mode 2 and key is on Automatic. Enabling this function, the genset starts and remains running without powering the load. If you enable the "full-load test" function, the test is performed by commutating the load from mains to the genset. 1.8.4 MASTER START This function allows you to start the genset with the card key in off position. By closing a contact to the 52-53 terminals, the card will turn on and the genset start-up process will begin. Once it is started, the command for closing the load will be activated. This function limits the batteries consumption in those applications placed where there is no public mains and therefore where you can not plug in the battery charger. For example, a generator that powers an irrigation pump driven by a float, if the level in a tank drops, then the float activates the genset that, in turn, powers the pump. Once it has reached the maximum level, the float deactivates itself and both the genset and its card turn off completely, preserving battery power. The activation of this function is displayed at page 1 Icon Ref 1 MSTR N.B. This function is available only in mode 1. 1.8.5 MAINTENANCE REQUEST The activation of maintenance request signal is displayed on the screen with the following message:

“MAINTENANCE REQUEST”

The MC4 has a hour-counter for requesting maintenance, oil change, filters etc. Its activation does not determines any alteration to the operating system, but it shows the signal on the display. At page 8 of the screen, the remaining hours to maintenance are highlighted in detail. When the required maintenance time has been reached, then the hours of running that go past the request are indicated. To reset the writing you need to set in settings a second maintenance service interval (see timing menu parameter 12). 1.8.6 TELEPROCESSING The genset can be remotely managed via a "remote " communication (PC or modem or GSM) and it can intervene automatically. See the following descriptions at page 64. 1.8.7 SCHEDULED START-UPS It is possible to schedule the start-up and the shutdown of the genset at predetermined times, for each day of the week 8 events are possible. If a scheduled event is set, the following symbol will appear on the display at page 1. The schedule of single start-ups can be set in “clock” menu, parameter 3. 1.8.8 PROGRAMMABLE RELAY GENSET CONDITIONS There is a programmable changeover relay for reporting some of the most important states of the genset, i.e.: • Cumulative Alarm • Running Genset • Low Fuel • Overload • Presence of Mains • Activated Emergency



10/01/2010 ITA Pagina 21 di 72

• Start-up failure The programming of this relay can be set in "Settings" menu, parameter 15.

1.8.9 DIFFERENTIAL OR EARTH FAILURE PROTECTION The MC4 card verifies the current wasted through to the ground. Its action activates the opening coil of the machine switch and stops the genset after cooling time. During the functioning, if 80% of set current is exceeded, the following message will appear "exceeded 1 differential threshold ". The advance warning activates the siren in order to alert the operator with notice. Page. 10 of the display indicates the leakaged current, the programmed current and the set delay of intervention. The differential is equipped with a test, when the machine is running the message “TEST: Press the RESET / ENTER for 5 seconds" will appear at page 10 of the display. It is then possible to test the opening device. Technical characteristics: • Sensitive to sinusoidal waves, divided sinusoidal, button, button with continuous component up to 6mA. • Operating Frequency 47 - 63 Hz • Intervention Current I∆n programmable from 0.03 to 5 A. • Programmable Action Time from 0.1 to 5 seconds. • Instant Action Time within 60 milliseconds. • Negative Security (NA) on opening coil at current launch. • Toroid to use 500 / 1 turns optimized on Revalco • Auxiliary supply range + / - 20% • CEI EN 60947-2 CEI 64-8 Referenced rules WARNING! The differential protection of the generating set is not to be intended as a "circuit breaker" protection because the settings have been made to reconcile the operational safety but also the continuity of service (standard setting 300mA rit. 3 secs). The installer must therefore ensure coordination in the selectivity of all the differential protections, so that end-users can work safely. 1.9.10 ELECTRONIC OVERLOAD (51) AND SHORT-CIRCUITS (50 ) PROTECTION

The generators are provided with power expressed in KVA as the actual limit of genset capacity is given by the amount of Amperes allowed on the generator windings. It is thus provided an electronic protection to prevent any damage to the alternator.

OVERLOAD (51):

Whenever the nominal current of the genset is exceeded, after a set time, the genset contactor will open (and if set, the machine switch will open simultaneously). Then we will receive the alarm report for overload and the shutdown of machine after engine cooling time.

10/01/2010 ITA Pagina 22 di 72

SHORT-CIRCUIT (50): It intervenes immediately when the load current exceeds the value set for a time of 1". The shutdown occurs in the same way as overload. 1.9.11 REVERSE POWER PROTECTION (32) Using the QPE-C/MC4 with gensets that are predisposed to work in parallel, the protection against REVERSE POWER can be activated. This protection starts working when the generator absorbs current instead of supplying it. The detection of reverse power is based on a math calculation on cosφ, so only when the cosφ is L - or C – then we have reverse current in the generator.

1.9.12 ALARMS HISTORY

Premendo contemporaneamente I tasti “candelette” T3 ed “Enter” T4 per 3 secondi si attiva lo storico degli allarmi dove è possibile vedere gli ultimi diciotto eventi di allarme. Quando si verifica un allarme tutte le misure e le videate vengono “congelate” e memorizzate, e sono pertanto consultabili. Quando si entra nello storico compare la seguente videata:

1.9.13 FUEL PUMP COMMAND The QPE-C panel is programmed to control the fuel pump to automatically refill the tank daily. Through the fuel level sensor, you can operate the pump for maintaining the level of the tank within programmable thresholds. 1.9.14 PROGRAMMING THE CARD THROUGH USB PORT Through a USB Port it is possible to program the setting parameters by directly tranferring the setting file on MC4 card. It is also possible to save the card settings from the card to the USB, to configure a second one in an identical way. (See setup menu).

1.9 INTERPRETATION OF ALARMS AND CONTROLS

WARNING! It is strictly forbidden to perform any action to parts under volt age.

1.9.1 1.9.1 WHAT TO DO IN CASE OF GENSET FAILURE When there is an alarm condition, it is displayed on display at page 1 . For any failure, press the ACK button once to silence the siren, then check the cause of arrest and press the RESET button to reset all functions. The causes and intervention are different according to the type of fault:

1. LACK OF FUEL If this alarm goes off, you must restore the level of fuel within the set time (default is 5 minutes). Otherwise the genset shuts down automatically to prevent the emptying of fuel filters.

2. FUEL RESERVE If this alarm gets activated it indicates the pre-alarm that anticipates the lack of fuel (default is set to 5%).

3. DYNAMO FAILURE It indicates a malfunction of the battery charger dynamo. It requires the intervention of a technician. If enabled, it causes the automatic shutdown of the engine.

4. LOW OIL PRESSURE It indicates a malfunctioning of the engine lubrication system. Check the oil level and refill it if necessary. If the problem persists, please require the intervention of a technician. This alarm causes the immediate shutdown of the engine.

5. HIGH ENGINE TEMPERATURE It indicates that engine coolant temperature is too high. Check level and refill it if necessary. If the problem persists, please check the cleanliness of radiator and the possible presence of foreign bodies that restrict the passage of air to the inlet valves or to the radiator itself. The high temperature of the engine can also be caused by a prolonged overload of the engine, if it is so please reduce the load applied. If the problem re-occurs, it is necessary to require the intervention of a technician. This alarm causes the automatic shutdown and the cooling of the engine.

6. LOW LEVEL RADIATOR WATER It indicates that there is no coolant liquid in the engine. Stop the engine as soon as possible and let the machine cool down. Reset the level as indicated by the



10/01/2010 ITA Pagina 24 di 72

service manual of the engine. This alarm generates only a warning (alert) but the genset keeps operating normally.

7. PRESENCE OF WATER IN THE FUEL It indicates the presence of water in the fuel. Stop the machine and clean both the filters and the tank for operating under these conditions could severely damage the injection system. This alarm provokes the shutdown of the machine only if programmed.

8. MINIMUM BATTERY VOLTAGE It indicates that the battery is flat. Please ensure the charging or replacement.

9. MAXIMUM BATTERY VOLTAGE It indicates that the battery charging alternator (dynamo) is charging too much and you risk damaging both the battery and the electrical equipment of the machine. It requires the intervention of a technician. This alarm causes the automatic shutdown of the genset only if programmed.

10. HIGH WATER TEMPERATURE It indicates the pre-alarm that anticipates the high engine temperature alarm (signal from analogical sensor) programmable threshold. The warning does not cause the arrest of the genset.

11. INSUFFICIENT OIL PRESSURE It indicates the pre-alarm that anticipates the low oil pressure alarm (signal from analogical sensor) programmable threshold.

12. MINIMUM WATER TEMPERATURE It indicates that the engine temperature is very low and therefore you must verify the efficiency of the engine pre-heater, if present. It is possible to start the engine even if this alarm goes off, but it is recommended to run the machine freely or lightly loaded until the engine temperature rises of a few tens of degrees. The threshold is programmable (default is 0 °).

13. OIL SENSOR FAILURE It indicates that the oil pressure switch has not re-closed when the engine stopped. This sensor is crucial for the proper functioning of the machine, so you can not start the engine with this anomaly. Please request the intervention of a technician to replace the oil sensor or to restore the electrical wiring.

14. START-UP FAILURE It indicates that after the programmed attempts to start, the genset has not started successfully. Please check the fuel supply circuit by manually purging it. If the problem comes back, please require the intervention of a technician.

15. STOP FAILURE It indicates that the engine has not stopped despite the stop signal has been sent by the panel. Please, verify the correct functioning of fuel solenoid or of arrest electromagnet. With engines that have can-bus control, it indicates a missed communication with the engine control box. In this case, in order to stop the engine, please act on the stop button mounted on the engine. (For ex. Volvo engines Tad series). To further verify, please request the intervention of a technician.

16. CAN-BUS DAMAGED It indicates the presence of one or more alarms sent by the engine control box. To display the list of warnings go to page 13 of the display. The identification numbers will be given and through the engine manual you can track the cause of the problem. This anomaly, based on the gravity of the situation, may provoke the immediate shutdown of the engine.

17. L1-2-3 PHASE OVERLOAD It indicates that one of the outgoing phases from the generator is supplying a current bigger than the maximum allowed. Please test the applied load and if possible, better distribute the load. This alarm causes the arrest and cooling of the machine.



10/01/2010 ITA Pagina 25 di 72

18. OUTPUT SHORTCIRCUIT It indicates that there is a fault on the output line. Please check the electrical connections between the genset and the powered plant. This alarm causes the opening of machine’s switch and the immediate arrest of the machine.

19. L1-2-3 PHASE VOLTAGE TOO HIGH It indicates that due to a serious load imbalance between the three phases, one of the three provided voltages is too high. Better balance the applied load on all three phases. If the problem persists, request the intervention of a technician.

20. GENERATOR VOLTAGE TOO LOW It indicates that the output voltage from the generator is lower than the minimum allowed threshold. Please, verify that the engine runs correctly at 50 Hz and that the load applied to the machine is not excessive. To solve this problem, please require the intervention of a technician.

21. FREQUENCY / RPM TOO HIGH It indicates that the engine is running at a speed faster than the allowed one. In this case you run the risk of damaging both the machine and the electrical equipment connected. The activation of this alarm causes the immediate shutdown of the machine. To solve this problem, require the intervention of a technician.

22. FREQUENCY / RPM TOO LOW It indicates that the engine does not reach the proper number of rpm. Please check the fuel power system and if the problem occurs with load, it may be caused by an excessive power demand, thus reduce the load applied. If the problem persists, request the intervention of a technician.

23. POWER RETURN It indicates that the generator has absorbed energy instead of supplying it. Verify if it has made a wrong connection in parallel to a line already in voltage powered by the mains or by another genset. This alarm can also be generated by particular loads that under certain conditions act as generators (ex. hoists, lifts, etc.). The activation of this alarm causes the opening of the switch and the arrest of the genset.

24. DIFFERENTIAL PROTECTION INTERVENTION It indicates that there is an earth dispersion fault in the generator or in the load applied. At page 10 of the display the calibration values of the differential and the set delay of intervention are shown. In this page, you can also in real time display the current dispersed in order to estimate the threshold for action that has to be set (See differential setting menu). The intervention of this protection causes the immediate opening of the machine switch and the arrest of engine after the cooling phase.

25. DIFFERENTIAL PROTECTION THRESHOLD 1 EXCEED ED It indicates the pre-warning that anticipates the differential protection alarm. It is triggered when the 80% of set current as threshold for release is exceeded. This alarm activates the buzzer alarm that can alert the user in advance.

1.9.3 ELECTRICAL MAINTENANCE Any interventions must be carried out by specialized staff. If you need to access the equipment inside the panel, please follow these steps: 1. Turn the programming switch OFF. 2. Check the total arrest of the genset. 3. Divide up the mains line that powers the panel, by opening the general switch on the mains. 4. Open the panel and proceed to determine any possible anomalies of: • fuses; • Automatic switches; Once you have completed the maintenance, please repeat the operation in reverse order to restore original state. 1.9.4 MCCB RESET Some alarms can determine the opening of genset circuit breaker (lever in central position, TRIP). The latter must be restored by firmly pressing the lever down to position OFF and then to position ON



10/01/2010 ITA Pagina 27 di 72

1.9.5 MECHANICAL MAINTENANCE In case of failure to start because of an anomaly to the fuel circuit and in emergency conditions, here are some tips.

Resetting of the fuel circuit procedure

1. Set the change-over switch to (MAN), quickly press the START button without starting the genset: in this way it activates the 15/54 which powers the solenoid valve of fuel interception. 2. After filling up with fuel, please activate the hand pump located on the engine, until the restoration of the circuit shown by hardening of the pump force. 3. Execute the manual start-up command (we recommend a limit of start-ups to within the 10” and interrupt with pauses of 15" to allow for a good recovery of the battery).

1.9.6 PERIODIC CHECKS To maintain the genset efficiently, it is necessary to make regular checks in addition to those that are already planned by the engine manufacturer and the installer: 1. Check the electrolyte level of batteries every 15 days after installation and require the intervention of a technician if there is an excessive consumption. After the initial period, check every 30-60 days. 2. In gensets with engine pre-heater, check if the engine is warm at every check. Otherwise require technical intervention. (WARNING! A cold engine at low temperatures may have diffic ulty starting-up or powering once it is running ) 3. If the genset rarely intervenes in case of mains failure, please perform an automatic test monthly for at least 2'. 4. If new electric machines are added to the plant powered by the genset, please ask for a technical check to verify that the commutation CG / CR / Mains/ Genset is appropriate to the new load.

SUMMARY: Periodically check the electrolyte level on transpa rent batteries.

Tap the engine to check if it is hot (if equipped w ith pre-heater). Perform periodic manual or automatic tests.

2.3 ELECTRICAL CONNECTIONS BETWEEN MC4 MOTHERBOARD AND THE GENERATING SET

Here below, we will describe the functions of each single connector and terminal and also the connection modes. 2.3.1 J1 CONNECTOR POWER SUPPLY SYSTEMS C.C AND COMM AND RELAY The J1 connector is a 6 terminals connector step 7.5 and the connections are as follows: Terminals 1-2 battery powered. The power comes from the genset batteries and it is a voltage that can vary according to the genset setup. The supply voltage can be indifferently either 12 or 24 V, but it is tolerated a variation from 9 to 40v. The normal operating is guaranteed even when you have voltage drops to 5v that last 1 sec., phase that occurs when you insert the starter motor.

START-UP COMMAND

START-UP

GLOWPLUGS PRE-HEATING. 6

Terminal 3 Start control of starter motor (positive output). This terminal is connected with the starter motor, device that can absorb even 30A but only for a few seconds. The starter motor with key on manual gets activated every time you press “START”. With key on Automatic, the starter motor is managed by micro, with specific times and modes. Following the start input, the insertion of the solenoid (terminal 5) gets activated first and after a time adjustable via setup (start-up delay), the starter motor gets activated for a time that can be programmed (start-up duration). If it detects that the genset is running, the starter motor switches itself off immediately, if the genset does not start there is a break (start-up pause) and a subsequent attempt to start. The number of start-ups is programmable from 1 to 4 (number of start-up attempts). Every time you activate the starter motor, the green led next to the “START” button turns on. Terminal 4 Electromagnet stop control (positive output). This terminal is connected to a closing electromagnet that pulls the engine stop lever (only for old designed engines). With key on manual, this output gets activated every time you press the stop button. Even when you turn the key in 0 position, it gets activate for a programmable time (e.m. activation time) before the final shutdown of the card. Each time you activate the output, the red led next to the “STOP” button on Display module turns on. Terminal 5 Solenoid stop (positive output). This terminal is connected to the fuel solenoid which is always powered when the engine is running. If you use this terminal to power a can-bus type electrical box, please program the output as "electrical box supply" from the "Settings" menu parameter 25. In this way, the terminal will go on voltage immediately when turning the key on automatic or manual. Terminal 6 Engine pre-heating glowplugs supply (positive output). In case of engines equipped with pre-heating glowplugs, it is programmable for a set time (preheating duration). If this time is set to 0, the output is not activated. If the time is set to x seconds, it gets activated in different ways depending on how you turn the key. With key turned to manual, as soon as the key is turned, the output for the set time is activated (the activation is monitored by the corresponding led next to the pre-heater button). Then if you press the pre-heater button, the output gets reactivated, but only while the button is held down. With key on automatic, the output gets activated only after the start input and the starter motor command will be delayed until the time (duration of preheating) will be completed. Please see the diagram below. There is the possibility of guiding an engine pre-heating system through resistances supplied at 230V, by programming the sixth output properly (setup menu, parameter 13 pre-heater).

In this case, the sixth terminal can activate a contactor in continuous current to automatically turn off the pre-heater when the genset is running or it goes above the maximum set temperature (max). It automatically activates the pre-heater when the engine temperature goes below the minimum value (min) (this function is active only when the temperature transducer is connected to terminal 19). 2.3.2 J2 CONNECTOR CAN-BUS ENGINE CONNECTION J2 connector, 3-poles step 0,5, is the connector for the Can-bus communication with the engine. Terminal 7 can high, Terminal 8 can Low Terminal 9 cable shielding. If you activate the Can-bus communication (Can-bus menu) you will get, according to the engine types, either only alarms related data, or alarms and also start-up commands, stop commands, change rpm 1500/1800. The managed engines are Volvo EDC3 - Volvo EDC4 - Iveco - Deutz - MTU - J1939 standard. The Volvo EDC3 type engines have a complete protocol where you can start and stop the engine, get the genset running signal, get all the alarm signals, get water temperature, oil pressure, oil temperature, working hours, engine rpm, instant fuel consumption etc.. In addition to the on-board diagnostics. The Volvo EDC4 type engines, Iveco, Deutz, MTU have instead only the acquisition of the alarms, engine size and of the on-board diagnostics, while the start-up and stop are managed traditionally. 2.3.3 J3 CONNECTOR ENGINE PROTECTION DIGITAL INPUTS J3 connector of digital inputs towards the genset has 9 poles step 0.5. The input signals are always referred to ground. Terminal 10 Dynamo Input. This input provides an output to excite the battery charger alternator. It has a 3W load circuit that is automatically set according to the voltage supply to 12V or 24 V. This alarm input is active only when the engine is running, and it is delayed, so if while the genset is running it closes to ground due to the dynamo failure, the alarm goes off after 30 seconds. When the anomaly occurs, the alarm buzzer gets activated and on the first page of display it shows "Dynamo failure”. In setup you can decide whether this alarm must also stop the genset, see "Settings" menu parameter 9. In setup, you can completely exclude this alarm, see "Settings" menu parameter 8. Terminal 11 Oil pressure bulb input. This connection is crucial because it is an important alarm and it is also an input to determine the on-off state of the engine. This terminal must be connected an oil pressure-switch that, when the engine is not running (so the oil pressure is 0 Bar), is directly connected to ground (logic state 1). As soon as the engine starts running, the lubrication circuit goes in pressure and the pressure-switch will open (logic state 0). Considering the importance of this sensor, this connection is continuously monitored even when the engine is stopped, i.e. the reclosing of the contact occurs 2 minutes after the engine stops. If this does not happen the alarm "oil sensor fault” intervenes. Following the start-up of genset, this contact gets enabled as an alarm after a delay. (activation alarms delay). If it recloses, the alarm goes off immediately and stops the genset straight away. On the display the "low oil pressure alarm” is shown. IMPORTANT: The status of this contact is also needed to give the approval to activate the starter motor. If the contact is closed the starter motor will be activated regularly, if the contact is open (so the genset is running) any attempt to gear the starter motor will be stopped. The functions and alarms connected to the oil bulb can be disabled via the "Settings" menu parameter 7 "oil input exclusion". Terminal 12 High temperature water bulb input. This terminal is connected to a thermostat that closes to ground when the engine water temperature reaches a critical level. The closing of this contact causes an alarm with two modes of arrest, an immediate one or with cooling stage, both programmable in the "Settings" menu parameter 11. If the alarm occurs, the following indication " high temp. engine alarm" appears on the display, with the immediate release of the load (opening of the contacts at terminals 60-61) and the shutdown of the engine, after the cooling phase (if set). This alarm is active even on manual. If the sensor of engine high temperature has a Normally Closed contact, you can reverse the operating logic, see "Settings" menu parameter 10.

Terminal 13 Low fuel input. This terminal is connected to a floating which closes to ground when the tank is short on fuel. This alarm is active also when the genset is stationary and it gives alarms with or without causing the arrest depending on how it is programmed, see “Time” menu parameter 14. If the signal is active, the acoustic alarm gets always activated as well as the “Low fuel” reporting message on the display, but it causes the shutdown of the machine after a time programmable from 0 to 300 secs. If set above 300 seconds, the alarm goes to OFF and the shutdown is therefore excluded. Terminal 14 Low water level input. This terminal is connected to a sensor mounted on the radiator that goes to ground when the level decreases. If the signal is active, the acoustic alarm gets activated as well as the “Low level radiator water” reporting message on the display, the engine shutdown is not planned. It is possible to reverse the state of the input contact from Normally Open to Normally Closed. See "Settings" menu parameter 12. Terminal 15 Presence of water in fuel input. This terminal is connected to a sensor that goes to ground when it detects the presence of water in the fuel filter. If the signal is active, the acoustic alarm gets activated as well as and “Presence of water in fuel” reporting message on the display. The shutdown of the genset occurs only if set, see "Settings" menu parameter 16. Terminal 16 Available input 1. Different alarm sensors can be connected to this input, always referred to ground. The message that appears on the display in case of alarm can be set in setup, see “Settings” menu parameter 17 (default text aux.1). This input can be set in 4 different ways: - Reporting on display only - Reporting and buzzer alarm - Signalling buzzer alarm and shutdown - Signalling buzzer alarm and shutdown after cooling. See settings menu parameter 18. Terminal 17 Available input 2. Same mode as the previous one (see Settings menu parameters 19-20) Terminal 18 Emergency button Input. Normally closed to ground, if opened it causes the immediate shutdown of the engine and the “Emergency Button Activated” reporting message on the display. IMPORTANT: each alarm described above remains active even if the input re-opens (therefore stored). To restore the normal operating it is necessary to reset everything by pressing the Reset button.

2.3.4 J4 CONNECTOR ANALOGICAL INPUTS TO MEASURE ENGIN E PARAMETERS J4 Connector analogical inputs, 5 poles step 0.5. The inputs are always referred to ground, in this case the reference ground is separated from the supply ground (terminal 23). This is to avoid any errors regarding analogical readings when the card absorbs current. The connection of sensors to the analogical inputs automatically enables the view of measurements on the display. In the following pictures two of the most commonly used sensors are shown. .

Terminal 19 Water temperature input. This input is connected to a temperature sensor, via the “Settings” menu parameter 5. Five different models can be set: 1. Resistive temperature sensor standard Veglia/Vigil 120 C° 2. Resistive temperature sensor standard VDO 120 C° 3. Resistive temperature sensor standard VDO 150 C° 4. Adjustable 0-10v temperature sensor (linear course) 5. PT100 temperature sensor The transition from resistive sensor to 0-10v is automatic and does not need any particular connection. In Setup you can calibrate the measures in order to compensate the lack of precision of the automotive sensors. This input determines the view of the temperature on the screen. Three functions are associated to this input:

1. “high water temperature alarm" if a set threshold in Setup is exceeded (threshold menu parameter 10), it causes a pre-warning that appears on the display and with audible buzzer.

2. “minimum engine temperature" if the detected temperature drops below a set threshold (threshold menu parameter 18), the pre-alarm goes off and it appears on the display and with audible buzzer.

3. The detected temperature is used in “heater” function to activate a contactor that powers a water pre-heating resistance system (see terminal 6 function). In Setup you can set the thresholds for activation and disconnection of the pre-heater (see thresholds menu parameters 19-20).

If no sensors are connected to this input, then the line of temperature is not visualized and all the functions associated with it are disabled. The pre-alarms can be excluded/disabled by bringing the activation thresholds to OFF in the thresholds menu.

Terminal 20 Oil pressure input. A pressure sensor is connected to this input, via the “settings” menu parameter 6. Three different models can be set: 1. resistive pressure sensor Veglia 0-10 bar. 2. resistive pressure sensor VDO 0-10 bar. 3. Adjustable pressure sensor 0-10v (linear course). The transition from resistive sensor to 0-10v is automatic and does not need any particular connection. In Setup you can calibrate the measures and the “0 bar” in order to compensate the lack of precision of the automotive sensors. This input determines the view of oil pressure on the screen. A “low oil pressure” pre-alarm with programmable threshold is associated to this input (see thresholds menu parameter 11). The pre-alarm can be excluded by bringing the activation thresholds to OFF in the thresholds menu. CAUTION: DO NOT CALIBRATE THE 0 VALUE WHILE THE ENGINE IS RUNNING. To align the reading of zero, go to the "calibration" menu parameter 3 when the engine is stopped (pressure to 0) and then calibrate it by pressing the button "enter". Terminal 21 Fuel level input. A resistive linear sensor is connected to this terminal. It goes from 0 hom (full tank) to 300 hom (empty tank). This input determines the display on the screen of fuel level in percentage (%.) The following 3 functions are associated to this input:



10/01/2010 ITA Pagina 36 di 72

1. “Low fuel” pre-alarm that activates the reporting on the

display and it activate the buzzer when the level goes under/drops below the set threshold (see thresholds menu parameters 14).

2. Activation of the fuel pump connected to the terminals 36-37 when the level goes under a set threshold (thresholds menu parameter 12).

3. Stop fuel pump, when the level exceeds the maximum set threshold (thresholds menu parameter 13).

The pre-alarm can be excluded by bringing the activation threshold of thresholds menu to OFF. The stop of fuel pump is also guaranteed by an “overflow” safety floating connected to the terminals 39-40. Before setting the level, it is necessary to calibrate it (operation that takes place in the factory). The procedure that must be follow is as below: 1. Bring the floating rod to the minimum level. 2. Enter the Setup, calibration menu, parameter 1 3. Press "enter" to store the position 0%. 4. Bring the floating rod to the maximum level. 5. Move to Setup menu, parameter 2. 6. Press "enter" to store the level 100%. During the level installation, you must consider the actual excursion of the floating rod in both directions upper and lower. Therefore, place the floating as indicated here below:

Terminal 22 Analogical input available for pressure, temperature and levels measurements. It can be used exclusively in 0-10v mode and it is possible to add in Setup the setting of unit of measurement, the values that correspond to different thresholds voltage and the text that has to appear before the measurement. The taken measurement appears in the last line of page 2. To enable this measure, go into Setup menu “settings” parameter 14. Once the input is activated, the following submenu will appear: 1. M22 text (maximum 10 characters) 2. M22 unit of measurement (bar, C°, %) 3. M22 decimals (1-2 decimals) 4. M22 points setting (ten points corresponding to 0-10 volt) Set all the parameters by confirming them with Enter button.

Terminal 23 common mass of the tools that is equal to the minus battery. If the panel is more than 5 meters from the genset, the mass must be taken directly to the common of sensor to avoid errors in reading. This is because the overall measured resistance is influenced by the current on the minus battery. If the sensor goes to ground directly on the genset frame, please connect this terminal to the bolt closest to the sensor. 2.3.5 J5 CONNECTOR TOROID CONNECTION DIFFERENTIAL PROTECTI ON J5 2-poles connector step 0,5 connections to the toroid for detecting the leakage current (differential), mounted on demand. All the generating sets produced by Elcos to the European market have rigorously connected the neutral delta-star to ground (TNC or TNS system). This connection is made inside the terminal compartment of the generator. This configuration is always performed even if the machine does not have the differential protection. On demand, for specific applications or specific markets, the implementation of the neutral isolated from the ground can be required. Through the toroidal transformer placed on the delta star-ground bridge, the MC4 constantly monitors that the outgoing currents do not return to the ground connection (i.e. neutral delta star). When the detected ld current exceeds the set value, which means that a part of current is scattered to the ground, after a possible delay, it disables the load through the opening of the machine switch. The picture A represents the ground fault protection 87G, commonly used on our gensets (homopolar type protection) because apart from carrying out the protection against direct contacts, it also detects any possible leakages to the ground from windings of the generator itself. During the commissioning, the isolation between the N neutral and ground PE at the switch downstream should be verified, as their join interferes with the differential protection. Pic. A

BA The toroid to be used must have a turns ratio of 500 /1, the card is optimized with a Revalco TOR1D. If the leakage current set threshold is exceeded (after the differential delay time), the “differential protection intervention” alarm gets activated. It causes the view on the display and the release of the magnetoterm circuit breaker by a opening coil connected to the J7 terminals 30-31. It is also expected a pre-alarm, if you exceed 80% of the set threshold, the message "exceeding 1 differential protection threshold” appears on the display with consequent activation of the alarm siren.

2.3.6 J6 CONNECTOR AMMETER TRANSFORMERS CONNECTION 4-poles connector step 0,5, connections for ammeter transformers (CT) to detect the supplied current. The common terminal 29 must be connected to the terminals S2 of the ammeter transformers, the grounding of the common terminal is not required because it is already made internally the card. The transformers measures are used to determine the views of current on the three phases, of the three powers, of the produced kwh and of exceeding of overload (51) and short circuit (50) thresholds. The connection is very important, it is necessary to strictly respect the input direction P1 of CT and S1 and S2 connections. Connections: CT1 PHASE X-L1 Term. 26 CT2 PHASE Y-L2 Term. 27 CT3 PHASE Z-L3 Term. 28 Common Term.29 The CT used to guarantee protection against overload and short circuit, must have a minimum power of => 4VA. If the CTs also power other equipments, the power should be increased according to the power that those equipments require, plus the losses of the wirings. Consumptions table in VA per wiring meter.

The three current measures with CT ... / 5A are in 0,5 class up to 1000 A, in class 1 from 1000 to 2000 A and in class 1,5 from 2 to 3000A. The ammeter circuits consist of three 0,1Ω 5W resistors, with a dissipation of 2,5 W at maximum current of 5 A. They can work with a constant overload of 20% 6 A and they accept 15 A for 3" or 20 A for 2” for protection against short circuit. In Setup (settings menu parameter 2) you can set the transformation ratio of the different TA with the following scales: 60/5-100/5-150/5-200/5-300/5-400/5-600/5-800/5-1000/5-1500/5-2000/5-2500/5-3000/5. In Setup, it is possible to calibrate the 0 and the measurement of the ammeter readings (calibration menu to reset parameters 6-7-8 to calibrate parameters 15-16-17). The card has been optimized to work with Revalco ammeter transformers, TAR or TAM series. In case of single-phase system, the connection of the sole CT1 FASE X between terminals 29-26 is required.

Generator connections The thresholds for minimum and maximum voltage and frequency can be set in the "threshold" menu parameters 2-3-5-6. If the voltages measures are not precise, you can calibrate them in the "CALIBRATIONS" menu parameters 9-10-11-12-13-14. 2.3.8 J9 CONNECTOR FUEL PUMP SUPPLY. Three poles connector 0,75 step, line 230 volt of fuel pump supply, driven by a 10A relay that takes the voltage from the generator input line. The output is protected by a 4 A (F5) fuse. Terminals 36-37-38 neutral, phase and ground respectively. This output is activated: With key on manual, when you press the "Fuel Pump" (T2) button. With key on automatic when the fuel level in the tank varies. The automatic function is linked to the presence of the fuel level sensor (see settings menu paragraph 2.3.4). The fuel pump operation is monitored by a led placed next to the "Fuel Pump" T2 button. The pump is powered by the generator line, so it can work only with the genset is running. You can directly control pumps at 230volt max 350 Watts. For higher powers or three phase pumps, the use of a re-launch contactor is required. The QPE-C panel provides a wiring predisposition for single phase pumps. 2.3.9 J10 CONNECTOR FLOATING OVERFLOW. 2 poles connector 0,5 step, Terminals 39-40 connection to the safety floating potential free contact normally closed.

Setup: “settings” menu parameter 15. 2.4.5 J15 CONNECTOR MANAGEMENT OF MAINS-GENSET REMOTE COMMUTATION.

6-poles connector 0,75 step, connections for the management of mains-genset commutation. The MC4 card, in mode 2 with key on automatic, includes the management of the genset start-up when the mains voltage fail and the relative monitoring of consents to the line commutation from the mains to the genset, i.e. the monitoring of ATS panel (automatic transfer switch). These contacts can guide power contactors, motorized change-over or motorized switches. The connections to be made are as follow: Commutation with power contactors. The two power contactors (CR-CG) must have both electrical and mechanical interlocks (BM) to prevent genset-mains parallels which would cause irreparable damages to the generator. Commutation with motorized change-over. The motorized change-over (CM) will switch the load on the mains line (1) or on the genset line (2). Make sure that the supply to the change-over (supply) is taken from an always available source, such batteries 12/24 v or 230volt line from UPS. This will give us the guarantee of operation even without the mains.



10/01/2010 ITA Pagina 43 di 72

Commutation with motorized switches. in questo modo avremo la garanzia di manovra anche in assenza rete. Two motorized switches (IR-IG) carry out the mains-genset commutation. In order to avoid that dangerous manual operations will be done which would cause a mains-genset parallel, it is necessary to interpose a mechanical lock between the two switches. A further guarantee of safety is given by the electrical interlock that prevents the closing of a switch if the other did not open. Make sure that the supply to the switches (supply) is taken from an always available source, such batteries 12/24 v or 230volt line from UPS. This will give us the guarantee of operation even without the mains. N.B.The motorized switches have activating times that in some cases last a few seconds (time that it is necessary for the springs to be loaded by the M engine), therefore, to avoid any problems, please set the MC4 card commutation time to a bigger value than the time spent to load the spring (Setup time menu parameter 10). In Setup you can change some time associated with the commutation:

1. Genset contactor closing delay (after detecting the genset is running) see “time” menu parameter 11.

2. Commutation delay when the mains come back, see “time” menu parameter 9.

WARNING! The management of closing the mains line is always guaranteed and it always takes priority. No

matter in which position you put the key or if you disconnect the pa nel from the battery, the mains line management contact (terminals 58 60) remains always c losed.

2.6 TECHNICAL NOTES OF MC4 CARD 2.6.1 ENGINE RUNNING DETECTION It does not require any external signal. The check take place on the generator frequency. In the start-up stage, once reached 540 rpm corresponding to 18Hz programmable, we have the first signal that the engine has started. A second check free from the microprocessor is made by detecting the output voltage from the generator, when exceeded 200 volts the starter motor is disabled. If the oil bulb has not been disabled, you have a third check, i.e. it is checked that the oil bulb is closed (0 bar oil pressure, engine off) before entering the starter motor. If the check gives negative result, then the start-up gets blocked. Setup. Thresholds menu parameter 15 Engine frequency thresholds ON. 2.6.2 OPERATING WHEN THE MICROPRECESSOR IS BLOCKED The MC4 card was designed to ensure the card manual start-up even in case of total failure of the microprocessor. The start control with key in manual position is free from the microprocessor and acts directly on the starter relay, so we can start the machine and turn it off by turning the key to off. If the engine is totally controlled by CAN-BUS (for ex. Volvo engines) the start-up with blocked microprocessor is not doable. WARNING when the machine has started with blocked microprocessor, all protections and alarms are disabled, so the user takes full liability for generator failure or any damages caused to the powered users. 2.6.2 FIRMWARE SOFTWARE DISPLAY. MC4 card has two identical microprocessors, one for the display card (which manages keys functions) and one for the motherboard (which deals with all the measures and protections). Both microprocessors are periodically updated to improve the card performances. The software version installed on the motherboard is shown when powering up the first screen page. The display of the card display version only happens when you turn on the card by pressing the reset button on the motherboard (the button is located in the central part of the motherboard, and it is accessible only by removing the cover/lid).

2.7 ACCESSORIES COMBINABLE WITH QPE-C PANEL 2.7.1 MODEM FOR REMOTE MANAGEMENT OF GENERATING SET. The modem can send SMS with specified the type of alarm to 4 mobile numbers, then through a password you can start and stop the genset from a remote distance by sending an SMS. The sent message is in the selected language and it is preceded by the genset number (genset id modem menu). For example: Genset 1 "lack of fuel" The MC4 modem card is specifically designed to fit within the display card. The assembly of the modem card is realized as follows:

1. Turn the card key to “0” position 2. Remove the battery fuse F1 3. Remove the pre-cut sheet at the rear right side of the display card. 4. Insert the modem card, taking care to properly align the connector. 5. Fasten the modem to the sump with screws. 6. Connect the antenna. 7. Insert a SIM with disabled PIN. 8. Replace the fuse F1 back.

Once the mechanical assembly has been made, you must activate the modem using the appropriate menu (see page 54), by bringing the parameter 1 of the modem menu to a value other than 0 (if left to 0 the modem is disabled). In the modem menu you can enter and search all the phone numbers and change the password for the



10/01/2010 ITA Pagina 57 di 72

remote control. You can also insert numbers and passwords by sending SMS’ as described below. When you turn on the panel on page 1 of the display, the symbol of an antenna will be shown, and after a minute above this symbol will appear the marks that indicate the quantity of the received signal. If not, check the GSM coverage area or verify that the inserted SIM has the PIN disabled. Receiving and sending an SMS is indicated by the animation of notches above the antenna. The controls and configurations that can be sent via SMS are the following: Changing the password. The default password is 1234, to change this number you must send an SMS to the SIM number enabled in the modem and composed as follows: PWD3426#1234 The PWD writing indicates the control, 3426 the new password, 1234 the password that authorized the control. The control letters may be recognized both if written in uppercase or lowercase. Recovery reset. In case the user loses or forgets the password, it has been programmed a system reset which restore the modem back to the basic state by sending an SMS, for example: RESET#1234 The reset password is obviously always the same and is not modified by the user. Phone numbers insertion. To save the phone number where messages of alarm and status will be sent, you must send an sms with the following command: NUM1+3934724356487#1234 The NUM writing indicates the command, the following number 1 indicates that this is the first phone number included in the list, +3934724356487 is the phone number to be inserted, #1243 is the current password (if it has not been previously modified). 4 numbers are allowed. Deleting a phone number. To delete a phone number you have to send the following command NUM1#1234 where the number 1 that follows the NUM command indicates which out of 4 numbers has to be deleted. Start-up control To start the genset remotely, send the command followed by the password, START#1234 When the genset is running, if enabled in the modem menu, an SMS will be received indicating “genset running” of course this message will be sent to all numbers on the list. The remote start control is active only with key in automatic, and only if the card was configured with operating mode 1. Stop control To stop the genset remotely, send the command followed by the password, STOP#1234 When it is stopped, if enabled, the message “genset stopped” will be sent. The stop control is active only if the genset was started manually on site. Block of SMS’ If you want to block the sending of SMS’, then send the command followed by the password SMSOFF#1234 To reactivate them send the message SMSON#1234 It is also possible to partially exclude the block of SMS’ by sending the command SMSOFF13#1234 which disables only the numbers in 1st and 3rd position. To reactivate them, then message SMSON13#1234 must be sent. Numbers list If you want to see the list of numbers stored in the modem, send the command followed by the password LIST#1234



10/01/2010 ITA Pagina 58 di 72

You will receive a text message reporting the 4 numbers stored and their related activation status, i.e. ( E= enable, D = disable) IMPORTANT It takes three minutes before the modem becomes operational after the card has been turned on. All the alarms in this period are automatically ignored. If the modem fails to send the SMS, the “sending message failed ” will appear. Please check the coverage of GSM signal and the remaining credit. O.Q.MD-QPE-C ordering code 2.7.2 REMOTE DISPLAY.

Introduction The remote display is designed to provide the user with a remote interface of the generating set. Indeed, through this panel, you can see all the parameters and the alarms of the generating set. You can also start and stop the machine. Connections The connections required to operate the synoptic panel are two: the power supply and the connection to receive data. The panel must be powered with 24V dc voltage took from an external power supply (not provided). The connection for receiving data works through shielded twisted pair that connects the display (master device) to terminals 41-42-43 of MC4 card. The maximum allowed distance is 500m.

Prologue. The MOD-BUS is an industrial communication protocol that allows different devices (slave) to communicate to a concentrator device (master), which in turn allows you to view and drive all the connected devices. The connection is on port RS485, the standard communication format is RTU (binary) and through a two-wired cable you can make a remote teleprocessing up to 1 Km. The transmission type is the most widely used standard, i.e. 8,N,1 format or 8bit data, with no parity control and 1 stop bit. By enabling the setup MOD-BUS menu, you can set the ID address of the peripheral device from 1 to 32 (with ID to 0 the RS485 communication port is disabled) . The transmission speed can be set to: 4800-9600-14400-19200-38400, and stop bits can be increased from 1 to 2. Message format. To communicate between two devices, the message must be contained in a “wrapper” that is transmitted by a communication port to the other one. The MOD-BUS defines that this "wrapper" includes:

• The address of the device with which the master has determined the transaction • The function code to be executed • The data to be exchanged • The error check composed according to the CRC16 algorithm

The address Each of the slave devices within a mod-bus system must have an address that uniquely identifies it, in our case it can be set from 1 to 32. The function code The second character of the message identifies the function to be performed in the message sent by the master, which the slave responds with the same code to indicate that the function was executed. Standard functions are:

For more information please call your usual installer or refer t o our technical department. 2.9.4 BATTERY CONNECTION For transport safety reasons, the machines are delivered with the battery disconnected, the installer will then have the duty to connect it. The genset battery powers the QPE-C panel, if the tightenings of the cables on the starter motor or on the battery are not perfect, they can cause operating malfunctions. Faulty connections masses have frequently created problems to the alarms and measures functioning. It is important to carefully tighten the battery terminals. 2.9.5 SUMMARY OF CONTROL PROBES MOUNTED ON THE ENGINE The probes measure the operating engine state. From their efficiency comes the guarantee of the integrity of the engine itself. There are two types: Contact ones for controlling states of alarms, such as low oil pressure, high engine temperature, low fuel level, etc..; Variable resistance ones depending on the measure, to control the measuring instruments such as thermometers, pressure gauges, levels, etc.. With engines controlled via CAN-BUS, the acquisition of alarms and measures come directly from the engine control unit. There are still the sensors, but not directly connected to the QPE-C panel.

2.10 SERVICE PROCEDURES 2.10.1 FIRST START-UP PROCEDURE Before proceeding with the functional testing: 1. Turn the setup key to MAN. 2. Check the lighting of the display, if off then the battery may be disconnected. WARNING! Connect the

terminals and tighten them properly. 3. Press the start-up button until engine starts. 4. Wait for 20/30” to let the oil flow, or the time needed for a minimum preheating of the engine and then

plug the generating set switch in to power the load. 5. Check the rotating direction of engines in use (reverse two phases if contrary to normal). 6. Carry out simulations of alarm on probes to check the efficiency of wirings, if the switch is equipped with

open control, it will open at each alarm. 7. After each stop, reset and restart. 8. Control the shutdown manually at the end of testing. 9. If the panel shall operate automatically, then turn the key to AUT. And check the proper operation in the

chosen 1,2,3 mode. 2.10.2 PROCEDURE FOR REPLACING THE BATTERY • Turn the setup key to zero; • Replace the battery and check the program operation.

WARNING! All operations to connections while t he genset is running and the cables are loose must be absolutely avoided, because the batter y charger generators

in case of battery disconnection while the genset is running deli ver a voltage between 40 and 80 volts (destructive to electronics).

2.10.3 PROCEDURE FOR REPLACING MC4 CARD The MC4 card is programmed differently depending on the type of application and the machine on which is mounted. If the card was required and the serial number of the machine was previously specified, then it is will be delivered already programmed properly. If not, you must require the setup file that can be uploaded using a standard USB key. (See setup menu, USB section.) If you have the card, proceed as follows: Turn the key to 0 position. Disconnect all connectors from the card. Replace the MC4 card. Copy the SW1 setup placed on the replaced MC4. Reconnect all connectors back in the right order. Run an operating test.

WARNING! It is absolutely forbidden to make any intervention to pa rts under voltage.

3.0 MAINTENANCE MANUAL 3.1 ROUTINE MAINTENANCE The panel is designed to operate without needed maintenance, however, the following parts should be checked: TIME CHECKS TO BE MADE Every 30 to 60 days Battery electrolyte level Every30 days Water, oil, fuel level Every 30 days Engine pre-heater temperature (if present) Every 30 days Automatic genset test Every 6 months Battery efficiency

3.2 ELECTRICAL AND MECHANICAL MAINTENANCE. To do maintenance to the GENERATOR and the ENGINE, please refer to the respective manual, the following indications cover the electrical control parts and genset control.

WARNING! The panel is supplied by the mains and the genset. Be fore accessing for maintenance disconnect the mains and shut down the genset by turni ng the key to ZERO

3.3 TEST AND ALARMS SIMULATION Operation tests of the various automatic functions. The undervoltage protections, minimum frequency, low oil pressure a nd dynamo are active when the genset is running and after the set intervention of the generat or delay which enables the given load. Therefore, all simulations must be made after that time. 3.3 ENGINE PROTECTIONS On the engine, disconnect the wire from the respective sensing probe and connect it to about 3" to ground. The acoustic alarm will go off, then the genset will stop and this alarm will be reported. 3.4 GENERATOR PROTECTION Manually adjust the throttle lever or actuator, which causes a variation in speed in + or -, there is consequently a change in frequency Hz on the display. Act until the security threshold intervenes with activation of alarm and then stop. Minimum and maximum voltage. Manually adjust the VOLT on trimmer, placed on the electronic voltage regulator inside the generator. Operate first in one direction (+ or -) and then in the other one varying the output voltage until the protections get activated. After that, restore the voltage to the nominal value (test to be carried out rigorously with no load). 3.5 51 OVERLOAD PROTECTION Assuming that the load is not enough to exceed the maximum powered current, you should change the calibration of the overload to the load available current lower value. (see thresholds menu, parameters 3 and 4). When the genset is working in automatic mode, close the switch and insert the load. When passing the set current, after a delay, we will have the opening of the genset switch with its flashing led, the alarm and after cooling phase, the engine will shutdown.

3.6 TROUBLESHOOTING

All the panels are marked with a serial number indicated on the panel name plate. In some applications, the number to be considered is the genset serial number. The serial number are associated with all technical data and construction data of the panel, so you must refer to it for all requests for service or spare parts. However, it is important to detect and provide the following information:

1. battery voltage (12 or 24V); 2. mains voltage (230 or 400V); 3. genset power (KVA); 4. frequency (50-60 Hz); 5. reports on MC4 module when detecting a failure.
