Table 7 - Inputs/Outputs description


3 User interface

Table 8 - User interface

The user interface can be controlled through two different ways: • Directly on local browser using front panel LCD screen and keyboard • Remotely through an internet browser running on a PC

3.1 Internal browser description GENSYS can be configured and monitored remotely with a Web browser such as Internet Explorer or Netscape Navigator.

For local usage, GENSYS has an embedded browser which is able to display the same information pages as the remote Web browser.

The user can navigate through the different menus with the navigation bar and the / keys.

3.1.1 Navigation Mode The navigation bar provides 5 contextual keys. Depending on the menu displayed, different icons may appear above these keys, allowing the user to scroll up/down the pages or to select a link to a new menu or parameter.

When the user selects a parameter and presses the ‘ ’ key, the browser switches to the ‘Input mode’.

The 5 icons above contextual keys will change appearance depending on the type of parameter to change (list of choice, label, numerical value, password...).

When in ‘Input mode’, the key will discard the parameter changes and return to the ‘Navigation

mode’. The key will confirm the parameter changes and return to the ‘Navigation mode’.

The browser displays a white pointer in front of each link or parameter of a menu. A black pointer will indicate the active link or parameter. Figure 2- Browser link description shows these two pointers:


Figure 2- Browser link description

3.1.2 Input Mode

To change a parameter, first select it with contextual keys and press to switch to ‘Input mode’. New icons will appear above the contextual keys, depending on the kind of parameter selected.

Label modification:

Digital value modification:

List of options modification :

Figure 3 - Contextual keys for Input Mode

When the new parameter value is input, the user must press key to store and confirm the new value.

3.1.3 Save parameters configuration All GENSYS parameters used in configuration are stored in a FLASH memory. When a parameter is changed by the user, the new value is stored in a RAM memory. This new value will be effective as soon as it is entered, but it will be lost if the GENSYS power supply is cut or too low. To save the new

parameters in FLASH, you must use “SHIFT-I”. The user must press both + keys together. This will start the backup sequence and store all parameters in the FLASH memory. Now, the new parameters will be effective even after a power supply failure.

3.1.4 Password protection The GENSYS has different password levels, allowing access to more or less critical parameters or

menus. When the password page is shown on the LCD display, the user must first press on the key (like for other parameters) to switch to the ‘Password Input mode’.

Figure 4 - Password input mode display

Three lines of characters (upper case and lower case letters and ‘0’ to ‘9’ characters) will appear along with 5 icons above the contextual keys.

NOTE:

Due to the great number of parameters. The back-up procedure may take a few seconds. It is thus essential to save parameters when the motor is stopped. To save all

parameters, the user must press at the same time on both + keys on the GENSYS front panel. Otherwise, the new parameters will be lost when shutting down the GENSYS.


The first four contextual keys allow the user to move the cursor up, down left or right onto the desired character. The last key (OK icon) will validate the selected character and write it in the password line (a * will appear).

When all characters are entered, another press on the key will validate the password. If it is correct, the main menu will appear on the LCD display. Otherwise, the password page will be displayed again.

Default settings for the password are:

• Level 0: no password entered, just press "Enter" key. • Level 1: 1. • Level 2: Only for distributors.

The password of your level and those lower can be changed in the system menu.

Note: the menus might differ according to the security level of the password entered.

3.2 PC browser GENSYS provides an efficient way of configuring your application thanks to its embedded Web server.

It is thus possible to access the different menus with a simple Web browser such as Netscape Navigator or Internet Explorer. However, it is not recommended to be connected with the PC while the engine is running.

Before connecting with the GENSYS you have to configure your computer as described in the next chapter ". The next figure show a typical GENSYS menu accessed from a PC Web browser.

Figure 5 - Typical menu page

In this page, the user can choose from among 6 submenus (Generator electrical meters for example). It is also possible to scroll up/down the other pages of the menu with the page up > links. The ESC link acts in the same way as the GENSYS ESC key: it will display the parent menu.

The last 3 links are identical to the Fault / Alarm / Information key on the GENSYS front panel.

The next figure shows a typical configuration page. The user can change 5 different parameters (in this case, two numerical values and three option lists) and send them to the GENSYS using the [Save] button. Clicking on the [Save] button changes the parameter immediately.


Figure 6 - Typical configuration page

3.2.1 Setting up Windows XP Connecting a GENSYS with a PC is similar to connecting to Internet with a modem. GENSYS works as a modem and the integrated software works as an Internet provider. GENSYS also provides 1 web server. This web server sends HTML pages to your PC, and your PC browser is used to display it. Live data is refreshed with the JAVA applet.

4 Operating modes With the GENSYS unit, three main operating modes and one special mode are available to allow you to control your generator.

Modes are:

• Manual • Automatic • Test Mode

4.1 Manu mode In manual mode, it is possible to control the generator with the front panel of the GENSYS. All steps from engine start to paralleling are controlled by pushing keys. To start the engine push the [Start] key and hold down until the oil pressure fault disappears. On the front panel, the 2 LEDs above the generator should light up. The left hand LED indicates that a speed greater than zero is measured, whereas the right hand LED indicates that a voltage other than zero is measured.

If a speed regulator is connected to GENSYS, it is possible to increase the speed with the F1 key, and decrease it with the F2 key.

If a voltage regulator is connected to GENSYS, it is possible to increase and decrease the voltage with the SHIFT+F1 keys and SHIFT+F2 keys.

When the generator is synchronized, it is possible to close the breakers with the 0/I keys.

Important: The internal synch check relay is always active, i.e. it is impossible to close the breaker if the conditions for closing are not met.

When the breaker is closed the corresponding LED on the front panel should light up.

As soon as the generator breaker is closed, the GENSYS is switched to droop mode for speed and voltage, i.e. the speed and the voltage will decrease when the load increases.

To stop the engine, push the Stop key.

4.2 Auto mode Speed and voltage droop are inhibited in this mode, the system is running isochronously, i.e. the speed and the voltage remain unchanged whatever the load. This mode has 4 main ways of operating: One generator with Change Over:

The generator starts with a remote start or in the case of mains failure. When the generator is ready (voltage, frequency), the mains breaker is opened and the generator breaker is closed. Should the mains return to normal conditions or remote start is off, after a programmed delay the generator breaker is opened, the mains breaker is closed and the generator set is stopped.

One generator paralleling with the mains (option 2):

The generator starts with a remote start or if there is a mains failure. Paralleling depends on configuration: NO CHANGE OVER, CHANGE OVER, NO BREAK CHANGE OVER, or PERMANENT Load sharing can be on a "base load" or "peak shaving" basis. Depending on the configuration, the generator will stop either when there is a remote stop or when mains power returns to a stable level.

Power plant with several generators without automatic load/unload:

The generator starts with a remote start signal, and parallels with the bus. If there is a dead bus, GENSYS will check with the other GENSYS units before closing the bus breaker (this depends on the


validation of the dead bus management). The load sharing is accomplished via the inter GENSYS CAN© or via the parallel lines. The generators stop with a remote stop signal.

Power plant with several generators with automatic load/unload:

The communication between GENSYS units is via the inter GENSYS CANbus and determines which generators start or stop. The number of generators used depends on load requirements (all generators receive the remote start signal but only start if necessary).

4.3 Test mode This mode tests the Auto mode. When you press the [Test] key, the engine starts as if there was a remote start, and GENSYS will carry out the standard Auto mode sequence. To exit “TEST MODE”, push the [AUTO] key.

4.4 Semi Auto Mode Similar to Auto Mode, except that to pass from one state to another you press a button. The following illustration shows the various states.

Figure 9 - State machine


5 Typical start sequence for fuel engines During the start sequence protections are inhibited. This concerns all engine protections. When the engine reaches the required state (E2057 = 6, see next figure) the protections are activated. A timer can be added to inhibit protections during the "safety on" delay (E1514). The timer will start when E2057=6.

In Change over mode, as shown in Table 10- Typical change over mode configuration, the generator starts and takes the load when a mains electrical fault occurs. When mains power returns, the generator breaker is opened and the mains breaker is closed after a pre-set delay. For the generator to start when mains failure occurs, either a protection (mains or other) or a digital input has to be configured as a "Mains electrical fault".

If remote start is on when mains are present the generator starts, GENSYS opens the mains breaker, then closes the generator breaker and takes the load.

Table 14 - Typical basic configuration for GENSYS with parallel lines modules

When GENSYS is in ILS compatible mode, the active power sharing is handled via the parallel lines. You have to disconnect the AVR output (H2-H4) and have an external device control the reactive power (CT droop...).


6.4 Multiple generators with static paralleling This mode is useful as it allows: • Gradual magnetization of the step-up transformers (no transient short-circuit). • Full plant availability in less than 10 seconds.

6.4.1 Configuration • One GENSYS per genset. • CAN bus must be connected between GENSYS units. • An "Excitation" output (e.g. exit C1) must be configured on each GENSYS unit. • GE breaker must be powered by 24VDC (so as to close without AC). • In the Setup menu / plant overview / sync mode. E1177 must be set as "A stop". • The value of the maximum excitation rpm is set with E1896 (default: 97%). • The alternators must be identical. • Each GENSYS must be equipped with a speed sensor (magnetic sensor / Pick-up).

Figure 13 - Static paralleling with 4 generators coupled together in emergency situation

6.4.2 Sequence: • Loss of voltage -> Dead Busbar • Each GENSYS is ordered to start (Terminal J3). • CB1, CB2, CB3 & CB4 close as ordered by the GENSYS units. • DG1, DG2, DG 3, and DG4 start. • All generators reach the speed defined by the E1896 setting (CANBUS synchronization). • All C1outputs close simultaneously to activate excitation (after dialogue between GENSYS

units). • Alternator voltages increase gradually at the same time. • The plant is available to take up required load. • Breakers are closed when engine is stopped. • There is a residual voltage of 80V.

Table 15 - Typical basic mains paralleling configuration

In all mains paralleling modes, if a "mains electrical fault" is set (via protections or digital inputs), the generator starts and takes the entire load upon mains loss even if the remote start is off. In all cases, you have to set a mains protection in order to determine the behaviour of your generator when mains power disappears.

6.5.1 Mains paralleling modes: Choice of mains paralleling mode is configured through parameter E1178.

No Break CO (No break change over):

When remote start is on, the generator starts, synchronizes and parallels with the mains, then takes the load (ramps up). Once the mains are unloaded, GENSYS opens the mains breaker. When remote start is off, the mains takes the load in the same way as the generator did previously. If the generator started for a mains failure, when mains power returns the GENSYS synchronizes the load transfer (ramps down), opens the breaker and then stops the generator.

Figure 16 - Typical sequence in No Break CO mode

Permanent:

When the remote start is on, GENSYS starts the generator, synchronizes and parallels with the mains, then ramps up load until it reaches its set point. In base load mode (E1153), the generator has a constant load and the mains take the utility load variations. If the utility load is less than the generator


set point, mains are in reverse power. In the peak shaving mode (E1153), the mains have a constant load and the generator takes the utility load variations.

7 Installing and commissioning a GENSYS application

7.1 Wiring diagram

7.2 Installation instructions: The GENSYS module has been designed for front panel mounting.

Indoor or outdoor installation is possible as long as the following requirements are met:

• The chosen cabinet must meet the standard safety rules of the workplace.


• The chosen cabinet must be closed during normal use to prevent the user from coming into contact with power cables.

• Only the front panel must be accessible during normal use. • In accordance with the Bureau VERITAS marine agreement, the module must not be installed in

areas which are exposed to the weather.

7.2.1 Panel cut-out:

Figure 22 - Panel cut-out

Note: Cut-out must be cleaned of any metal dust before mounting.

7.2.2 Mounting: To secure the GENSYS onto the panel, use the special kit provided with the module. The kit contains 4 screws, 2 brackets and 1 mounting tool.

Figure 23 - Mounting kit

1. Remove the connectors.

2. Pass the module through the panel cut-out. Ensure that the gasket is properly positioned on the panel and that it is flat.

3. On the rear side of the module, insert the first bracket into the two holes on the upper edge of the module and push it to the left.

Figure 24 - Mounting brackets on GENSYS

4. Use the tool which is provided to screw the bracket gently onto the panel (just to hold the module in place)

5. Insert the second bracket into the two holes on the lower edge of the module and push it to the right.

6. Use the tool to screw the bracket gently onto the panel.

7. Tighten brackets gradually until the module is firmly secured.

8. Plug in the connectors.

7.2.3 Earth grounding: Earth grounding of the GENSYS must be made with two M5 screws & fan washers. Use a short 4mm² cable to connect the unit to earth (see below).

Figure 25 - Earth grounding

For UL homologation, the screw must be hexagonal with green head.

7.2.4 Wiring guidelines: The power cable must be kept separate from the communication cable. The communication cable can be installed in the same conduit as the low level DC I/O lines (under 10 volts). If power and communication cables have to cross, they should do so at right angles. Correct grounding is essential to minimise noise from electromagnetic interference (EMI) and is a safety measure in electrical installations. To avoid EMI, shield communication and ground cables appropriately.

If several GENSYS are used, all the power supply 0V (pin K3) must connected together with mini 10mm².

WARNING :

Please read the following recommendations to avoid any hardware damage to the GENSYS CANBUS Driver (not isolated).

Power supply to circuit breaker Terminal K3 (0V) should never be disconnected. The battery circuit should only be opened using a breaker placed between the battery's positive terminal and the K2 terminal (Power supply +).

Note: If the K3 (0V) terminal is disconnected and the bus bar voltage is applied to the GENSYS,

there is the risk of getting AC voltage on the CANBUS terminals.


Interconnection of all battery negatives

Figure 26 - Interconnection of all battery negatives

Rental fleet & HV generating sets CANBUS isolators are recommended for generating sets used for rental fleet, Marine, or High Voltage switchboards.

Figure 27 - Connecting CAN bus with isolators

Note: These isolators are fitted to prevent any damage due to a disconnection of any K3 terminal from the inter-negative connection. These isolators can be supplied by CRE Technology with the reference A40M0.

7.2.5 Vibrations: In case of excessive vibration, the module must be mounted on suitable anti-vibration mountings.

7.2.6 Real time clock battery: If the battery is disconnected, remove the rear panel and connect a 3V battery to the ST1 jumper (+battery: ST1 up; -battery: ST1 down). Battery maintenance must be provided separately from the GENSYS
