1. Introduction VAMP 220 is a state-of-the-art arc protection system for electrical power distribution systems. By using VAMP 220 in switchgears considerable safety improvements are obtained in the form of minimized injury and damage in case of an arc fault. VAMP 220 uses modern microprocessor technology and provides numerous new features previously not found in similar devices. Key features of VAMP 220: a total operating time of 7 milliseconds exact location of the activating arc sensor self-supervision of the entire system system wiring using standard copper cables self configuration. In addition to the high-level requirements set for protective relays, VAMP 220 meets the most recent EMC-standards.

Figure 1-1 VAMP 220 arc protection system.

VAMP 220 is a modular system composed of a master unit, slave units, arc sensors, temperature sensors, and possible trip multiplying units and interface units. The master unit VAMP 220 includes all the main functions of the arc protection system, such as overcurrent, arc and temperature supervision. Up to 10 slave units can be connected to a master unit. The slave unit VAM 12 CD serve as a link between the sensors and the master unit. Each slave unit can be connected to ten fixed arc sensors, one temperature sensor and one portable arc sensor.


VAMP 220 / 220R


The arc sensor VA 1 DA is activated by strong light which it transforms to a current signal. The signal is tranferred via the slave to the master unit. The portable sensor VA 1 DP is an arc sensor that can be temporarily connected to a slave. Attached to persons it improves the personal safety during work in live switchgears. The master unit provides up to four trip output channels for tripping circuit-breakers. By connecting the trip multiplying relay VAR 4 CE to the outputs, up to 16 trip outputs can be obtained. The standard sensor cable length is 6m. Arc sensors can be con-nected over longer distances, up to 20 m, using a sensor with a shielded cable. Thanks to the modularity, the system can be flexibly adapted to a variety of arc protection applications, ranging from simple systems with one master unit and one slave unit to complex solutions comprising multiple master units, for instance, in applications with selective arc protection. VAMP220 suits both low voltage and medium voltage switchgears. It can be installed in new as well as existing switchgears.

Figure 2.1.1-1 Master unit VAMP 220/220R.

When the conditions for an arc short circuit occur (simultaneous overcurrent and arc signal), the master unit trips the circuit-breaker(s) of the incoming feeder(s). A master unit can trip up to four circuit breakers. If more than four parallel trip outputs are required, the trip multiplier relay VAR 4 CE can be used.


VAMP 220 / 220R


The tripping of the arc protection system can be backed up by employing the built-in circuit breaker failure protection subunit. This unit trips another breaker, for instance, the upstream circuit breaker, in case the main circuit breaker should fail to operate. Thus, it gives the system redundancy and increased security. The master unit includes a unidirectional arc input, a unidirectional current dependent arc output, and a bi-directional arc in/output. Furthermore, the master unit is equipped with a unidirectional overcurrent output and a bi-directional overcurrent in/output. With these properties a selective arc protection can be built even in complex distribution systems. Any voltage within the range 40 - 265 V ac or dc (or optionally 18 - 36 V dc) can be used as auxiliary supply voltage for the master unit. All internal supply voltages required by the system are derived from the auxiliary supply voltage of the master unit. NOTE! It is recommended that the auxiliary voltage is fed from a secured source, which is unaffected by a possible arc fault.

2.1.2. Functional description The current inputs of the three-phase overcurrent subunit (220) or two-phase overcurrent and E/F subunits (220R) are connected in series with any other possible protective devices of the switchgear. The start value of the overcurrent (220) / overcurrent + E/F (220R) subunits are set according to the preconditions determined by the arc short circuit and/or E/F current (220R) , independently of the settings of any other protection systems within the switchgear. The start value is set with a potentiometer knob on the control panel of the master unit (220). VAMP 220R has a separate E/F setting. The arc protection unit obtains its measuring signals from the slave units, to which the arc sensors of the system are connected. The unit starts when one or more of the system's arc sensors are activated. At a simultaneous activation of the overcurrent unit (220) / overcurrent or/and E/F unit (220R) and the arc protection unit, the arc protection system operates and the output elements trip the circuit-breakers.

NOTE! No operation takes place if only one unit (either the overcurrent or arc protection unit) is activated.


VAMP Ltd


NOTE! The arc, overcurrent and E/F (220R) stages can also be activated from external BI/O signals. The circuit breaker failure protection subunit (CBFP) starts if the preconditions for the operation of the arc protection unit have not disappeared when a set operate time (80, 100 or 150 ms) has elapsed since the arc fault trip. The CBFP, which is optional, trips its own circuit breaker. When not used, its trip contacts are left unwired. If not used for circuit breaker failure protection, the CBFP output contact (TRIP3) can be set to operate in parallel with the actual trip circuit (TRIP1), if two circuit breakers are to be tripped simultaneously. The desired function for the third trip circuit (TRIP3) is to be specified when ordering the master unit. By default, TRIP3 is programmed for CBFP function with a time delay of 80 ms. Figure 2.1.2-1 shows the TRIP signalling block diagram of VAMP 220.

2.2. Slave unit VAM 12 CD The slave units, which can be mounted into suitable places in the switchgear compartments, serve as links between the sensors and the master unit. Each slave unit can be connected to ten arc sensors and one portable arc sensor. Up to 10 slave units can be connected to one master unit. The master unit and the slave units are interconnected by means of modular cables. The slave units contain, for instance, the self-supervision of the connected arc sensors.

Figure 2.2-1 Slave unit VAM 12 CD.

When the system operates due to an arc fault, information of the sensor that caused the operation is forwarded by the slave unit to the master unit. The slave number and sensor number is then displayed by the master unit. The slave unit supervises all its sensors continuously. In an internal fault situation the fault information is transferred to the master unit and the fault can be viewed on the display of the master unit. A fault alarm is also given if an arc sensor connected to the slave unit remains in active state for more than 7 s. This can happen, for instance, if the arc sensor is exposed to direct sun light. At the same time the corresponding slave unit is disconnected from the master unit in order to prevent false circuit-breaker trippings. When the interference light disappears, the function of the slave unit is restored.

2.3. Arc sensor VA 1 DA The arc sensor is a light sensitive element, which is activated by strong light. Arc sensors should be mounted in the switchgear cubicles in such a way that they cover the space to be protected as completely as possible.


VAMP 220 / 220R


Figure 2.3-1 Arc sensor VA 1 DA.

A sudden increase of the light intensity is interpreted as an arc fault. The electronic circuits of the sensor transforms the light message into a current message and transmits it to the slave unit, which forwards it to the master unit. The sensitivity of the sensor is nearly equal over the front side. At the rear side the sensitivity decreases remarkably. See Figure 2.3-2. In a switchgear, however, the light caused by an arc is reflected from the walls. Therefore, the mounting position of the sensor is not critical. The standard sensor cable length is 6 m. As an option, a shielded cable can be used for distances up to 20 m.

2.4. Portable sensor VA 1 DP This module is a portable sensor element which can be temporarily connected to the slave units. It is used to improve personal safety during work, for instance during maintenance work, in a live switchgear. The sensor should be located close to the place where work is done. It can, for instance, be attached to the breast pocket of the service man's shirt or boiler suit. The function of the portable arc sensor equals that of the fix-mounted arc sensors. The difference is that the portable arc sensor can be moved around within the reach of the connection cable.


VAMP Ltd


Figure 2.4-1 Portable sensor VA 1 DP in use.

The connector of the portable arc sensor can be plugged into the SENSOR connector of any slave unit of the arc protection system. The portable sensor should be attached in such a way that the sight is clear towards the working place.

NOTE! To avoid false activations, the portable arc sensor must be dis-connected from the slave unit immediately after use.

2.5. Trip multiplier relay VAR 4 CE With the VAR 4 CE multiplying relay the TRIP signals can be multiplied. Each multiplying relay has four ultra fast trip outputs, each of which can trip its own circuit breaker. Any combination of NO and NC contacts is available (to be specified in the order, see Figure 5.6-1 and table 9.3-1).

Figure 2.5-1 Trip multiplier relay VAR 4 CE.


VAMP 220 / 220R


Up to four trip functions are available by connecting TRIP1 and/or TRIP2 output to the control inputs of the trip multiplier relay. Auxiliary supply voltage is available from the 24 V OUT terminals of the master unit.

2.6. Systems with multiple master units Especially in medium-voltage switchgears the power may be fed from two or more infeeders. At an arc fault situation, each infeeder that can supply short circuit power must be tripped. In these applications, the arc protection system may include several master units, that is, one master unit per infeeder. In applications with multiple master units, the master units are interconnected via the BI/O connectors. When an arc sensor in the system is activated, information is transferred over the BI/O lines to all master units in the system. As a consequense, all master units with the overcurrent subunit activated will trip their respective circuit breakers. If a master unit connected to the BI/O lines is tripping, and the arc or overcurrent activation comes from a BI/O connection, the identifier of the activated BI/O line will be shown on the display.

2.7. Selective arc protection The master unit facilitates a selective arc protection even in more complex electricity distribution systems. As mentioned earlier, it includes the following input/output modules:

• unidirectional arc input • unidirectional arc output (current dependent) • bidirectional arc in/output • unidirectional overcurrent output • bidirectional overcurrent in/output.

By utilizing these features, complex busbar systems can be divided into separate zones. Each zone includes the parts of the distribution system that are limited by two or more circuit-breakers. See the example in Figure 2.7-1. Selective arc protection means that all zones are protected independently of each other. In the example in Figure 2.7-1, VAMP 220 master units are used for tripping the circuit-breakers K4, K5, K6 and K7 as well as the actual infeeding circuit-breakers K1, K2 and K3.


VAMP Ltd


Suppose that an arc fault occurs in switchgear B in Figure 2.7-1, in a situation where circuit-breaker K3 is closed and the other two infeeding circuit-breakers are open. The arc fault power is fed via K3 to switchgear C and further to switchgear B by bus ducts E, A and D. The master unit of the bus duct D (which trips the circuit-breaker K6) obtains the unidirectional arc information from the B I/ O bus of the master unit in switchgear B. In other words, when an arc occurs in switchgear B, the arc information is forwarded to all master units that limits that particular zone, independently on their physical location. In the described infeeding arrangements the pre-conditions for an arc fault (arc signal and overcurrent) are fulfilled only in the master unit tripping the circuit-breaker K6. Therefore, K6 is the only circuit breaker that is tripped. In this example, the overcurrent BI/O lines are not used.

5.3. Installing master unit VAMP 220/220R

5.3.1. Mounting master unit VAMP 220/220R The master unit is designed for door mounting. It can be delivered with optional spacing adapters if the installation depth is critical.

Figure 5.3.1-1 Mounting the master unit.

5.3.2. Wiring the master unit, overview The master unit requires the following wirings:

• secondary circuits of the current transformers of the switchgear

• trip circuits of the circuit-breakers • alarm circuits • auxiliary supply circuits • protective earthing • connections to slave units (data communication and

possibly separate auxiliary supply) • connections to other master units (if the system

comprises several communicating master units). The five first mentioned connections are described in the next sub-sections. The connections to slave units and other master units will be described in sections 5.4 and 5.7 respectively. See the example in Figure 5.3.2-1, and the block diagram in Figure 5.3.7-1.

Wiring trip circuits of circuit breakers Connect the circuit-breaker trip circuits to the following terminals (max. four separate trip outputs): TRIP1: X1-7, X1-8 TRIP2: X1-9, X1-10 TRIP3: X1-11, X1-12 TRIP4: X1-13, X1-14 The output contact will close within 7 ms at an arc fault, provided that three-phase current measurement is used. If TRIP RELAY 3 is programmed for circuit-breaker failure protection (CBFP) (see section ), the trip signal is obtained after a set operate time of 80, 100 or 150 ms from the main trip signal in case the preconditions of an arc fault still exist.

NOTE! The function of the TRIP3 circuit must be specified when order-ing.


VAMP 220 / 220R


If more than 4 parallel trip circuits are required, the separate trip multiplier relay VAR 4 CE can be used. See section 5.6.

5.3.5. Wiring alarm circuits The alarm signals generated by the arc protection system (trip alarm, self-supervison alarm) can be forwarded to higher level switchgear supervison and control systems through the alarm output contacts.

Self-supervision alarms A self-supervision alarm is issued when the self supervision system detects a fault in the internal functions of the master unit or in the number of connected sensors. Connect the self-supervision alarm output to an SF change-over contact, either terminals X1-17, X1-18 (normally open) or X1-18, X1-19 (normally closed). See Figure 5.3.3-1. Under no-internal fault (healthy) conditions with auxiliary supply connected, the contact X1-17, X1-18 will be open and X1-18, X1-19 closed.

Trip alarms Trip alarms are generated when the arc fault system trips. Connect the trip alarm output to the NO terminals X1-15, X1-16.

5.3.6. Protective earthing Connect the arc protection system to the earth from the PE terminal marked on the back plate.

5.3.7. Wiring auxiliary supply Connect the auxiliary supply voltage to the Us-input, terminals X3-1, X3-2. Option 24 Vdc, polarity of wiring: X3-1: + and X3-2: -. NOTE! If possible, the auxiliary supply should be taken from a power source that is not interrupted when the arc protection system operates. CAUTION! Keep the auxiliary supply disconnected as long as mounting or wiring work is going on.

5.4.2. Wiring between master and slave The master unit and the slave units are connected together with a modular cable type VX 010. The modular cable carries all information between the master and the slave units, i.e. data in serial form and arc fault messages, as well as the auxiliary supply of the slave units. Connect the VX 010 cable to the X5 outlet (COM2) or the connector X3-5...10 (COM1) of the master unit. Both COM ports can be used simultaneously. CAUTION! If the connector X3-5...10 is used, pay special attention to the wiring of the signals. Faulty wiring may damage the communi-cation between the master and the slaves. Connect the cable to COM1 or COM2 on the first slave unit. Route the cable from the free connector of the first slave unit (COM2 or COM1) to the COM1 (or COM2) connector of the next slave unit, and so forth. See Figure 5.4.2-1.


VAMP Ltd


All the COM1 and COM2 connectors are mutually identical, i.e., the modular cable can always be connected to one or another. The maximum total length of the modular cable, when taking into account all slave units connected to the master unit, is 100 m.

5.5. Installing sensors

5.5.1. Mounting arc sensor VA 1 DA Mount the sensors in the switchgear cubicles in such a way that the detecting surface covers the space to be supervised as completely as possible. The sight must be free between the sensor and the supervised area. In open spaces (e.g. bus bar sections) there should be an arc sensor approximately every 5 meters. Due to the wide detection range of the sensors and the light reflection inside the switchgear, the mounting position is not very critical. The arc sensor can be mounted from the outside on a partition wall of the switchgear. Fit the active part of the sensor into a 10 mm hole in the wall and fasten the sensor with one 4 mm screw, see Figure 5.5.1-2. The arc sensor can also be surface mounted on a wall using the optional mounting plates VYX 01 or VYX 02.

NOTE! The arc sensor must not be exposed to direct sun light or any other strong light. Do not mount the arc sensor directly under a light source.

5.5.3. Connecting portable sensor The portable arc sensor can be connected to any slave unit in the system. When connected the portable sensor functions as a part of the arc protection system. Connect the portable arc sensor to the SENSOR plug-in type modular connector of the slave. Attach the sensor to personnel in such a way that the sight against the working object is free all the time. NOTE! Disconnect the portable arc sensor from the slave unit immedi-ately after use. If the sensor is left connected, it may cause false activations.

5.5.4. Arc sensor wiring over long distances If the standard cable of the arc sensor (6 m) is too short, a shielded arc sensor cable can be used for distances up to 20 m (arc sensor VA 1 DA -20S).

5.6. Installing trip multiplier VAR 4 CE If more than four trip outputs are needed at a time, the trip multiplier relay VAR 4 CE can be used. Attach the trip multiplier relay to a DIN rail close to the place where the master unit is mounted.


VAMP Ltd


Connect supply voltage from the terminals X3-5 (+) and X3-6 (GND) of the master unit to the terminals 1 (+) and 3 (GND) or 2 (+) and 4 (GND) in the trip multiplier relay. Note the polarity of the wires. Connect the required trip output to the terminals 5, 7 or 6, 8 in the trip multiplier relay. Connect the necessary trip controls to the terminals TRIP1 - TRIP4 in the trip multiplier relay, see Figure 5.6-2.

5.7. Wiring multiple master systems In applications comprising several master units, the master units can be interconnected for transfer of arc and overcurrent information via the BI/O (binary input/output) ports. The following BI/O ports are available as standard delivery (see also Figure 2.1.2-1): La> X3: 12 Arc input / output Lb> X3: 13 Arc output. Conditional. No activation if Ib> input

activated at the same time. Lc> X3: 14 Arc input. Controls TRIP RELAY 4 provided that

front dip switch 7 is ON and dip switch 8 is OFF. See section 6.7.

Ia> X3: 15 Overcurrent output Ib> X3: 16 Overcurrent input / output GND X3: 17

X3: 18 Ground for all BI/O signals

Table 5.7-1 BI/O ports.

To obtain transfer of arc information between two master units: • Connect the systems through the BI/O terminals X3-

12, 13 or 14 (+). • Connect the terminals X3-17 or 18 (GND). • To obtain transfer of overcurrent information between

two master units: • Connect the systems through the BI/O terminals X3-15

or 16 (+). • Connect the terminals X3-17 or 18 (GND).

NOTE! Note the polarity of the wires. In the example in Figure 5.7-1 arc information is transferred in both directions between the two master units. See also the application example in section 8.1. The slave units of the system should be connected to master units in the same zone.

Figure 5.7-1 Arc protection system with two master units (example).

5.8. Wiring systems with selective arc protection Wire the system as follows: • Connect the arc sensors of one certain zone in normal way

to the slave units. • Connect each slave unit to a master unit belonging to the

zone. • Connect the bidirectional arc information La via the BI/O

bus (terminal X3-12,17) to all master units in that zone. The unidirectional arc information (terminals X3-14,17, Lc>) can be fed from the master unit (terminals X3-12,17, La>) of the next zone. By doing so, the system will trip also the circuit breakers which feed the next zone. See Figure 2.7-1.

5.9. Checking wirings Check the secondary wiring by visual inspection and, when needed, by measuring, to eliminate possible incorrect wirings, which may cause malfunction of the system or associated devices.

5.9.1. Visual inspection Perform a visual inspection of the wiring. Especially check the wire bunches for adequate slack where needed over hinges. Check the screw terminals for correct tightness. Check, that no wire strands are protruding from the terminals.


VAMP 220 / 220R


5.9.2. Control by measuring Check the connections between the units and associated devices by using a circuit indicator lamp or buzzer. Check other possible connections by using recognized and reliable working practice.

Control modes The following control modes are available on the control panel of the master unit: RUN Normal operation INSTALL System configuration INFO Checking the system configuration TEMP SET Setting and checking temperature limits TEMP Reading measured temperatures CURRENT Setting and reading start value and measured

values of the overcurrent unit ERROR Reading and resetting internal fault memory Choose a control mode by browsing up and down among the modes using the up and down arrow buttons on the control panel. The selected mode is indicated by the LED at the left edge of the control panel.

NOTE! The arc protection system is always ready for operation as long as the auxiliary supply is switched on, independently of the control mode of the master unit. The master unit automatically returns to RUN mode in about 60 seconds after the last push of a button. The modes RUN, INSTALL, INFO, TEMP SET and ERROR can be set into an active state, where various measures can be taken, such as setting system parameters, erasing messages, etc. In normal state, system information can be read, but no measures can be taken. In active state, the display is flashing to indicate that the system is waiting for a command from the operator. To switch from normal to active state, press the S button. To return from active state to normal state, press the S button once again. Figure 6.1.3-1 shows a fast guide to the functions available in different control modes, in normal state as well as active state.

6.3. Setting addresses of slave units The communication between the master unit and the slave units will not work until the slave units have been given addresses. By means of the addresses, the master unit, for instance, identifies the sensor, which caused tripping. The slave addresses are numbers within the range 1 - 24. The addresses can be freely set, e.g. so that they comply with the numbers of the switchgear cubicles. NOTE! The slave addresses must be unique among the slaves connected to the same master unit, i.e., two slaves cannot have the same address. Set the addresses with the DIP switches situated on the front panels of the slave units. The address is formed by the sum of the weight factors of the switches set in ON position. The weight factors of the switches are listed in the table below. See the examples in Figure 6.3-2. Switch no. Weight factor 1 1 2 2 3 4 4 8 5 16 6 Not in use Table 6.3-1Weight factors of the DIP switches.

If the address of a slave unit is changed after the system configuration has been defined (see section ), the slave unit must be reset for the new address to take effect. The slave unit is reset by switching off the power supply, either by switching off the auxiliary voltage of the system or by disconnecting the modular cable (and a possible separate supply cable).

The master unit reads the physical system configuration, which takes about a minute or less. When done, the total numbers of slave units and arc sensors appear on the display.

NOTE! A slave unit without arc sensors is not counted.

NOTE! Portable sensors are not regarded. After reading the system configuration the master unit auto-matically moves to normal state. Check that the displayed configuration equals the physical system layout. Use the INFO mode as described in section to check the number of arc sensors connected to each slave.

NOTE! If arc sensors are added or removed later, a new system configuration must be done. Otherwise, the system will interpret the change as an internal fault.

6.5. Setting overcurrent values Select the rated current, 1 A or 5 A, with the selector switch on the front panel of the master unit, see Figure 6.5-1. Enter CURRENT mode using the up and down arrow buttons. Set the start current value, 1...6 x In and the start E/F value (220R), 0.01...0.1 x In, with the start current setting knob on the control panel, see Figure 6.5-1a and b.

Figure 6.5-1b Setting rated current and start current on VAMP 220R

In CURRENT mode, the set start current value can be read on the display of the master unit. In addition, the actual values of the three phase currents (220) / two phase and E/F (220R) measured by the overcurrent subunit can be read on the display. To move between the set value and the measured actual values, use the left and right arrow buttons. See Figure 6.5-2.

NOTE! The current values read on the display are expressed in units of the rated current. For instance, the reading 1.5 means a current of 1.5 x In, i.e. 1.5 x 1 A = 1.5 A or 1.5 x 5 A = 7.5 A depending on the rated current selected according to the nominal secondary current of the current transformer. The setting of the start value of the overcurrent subunit can be changed even if the master unit is not in the CURRENT mode. However, it is recommended that the start current is set in the CURRENT mode, since then the accurate set value can be viewed on the display during the procedure.

The overcurrent subunit measures all three phase currents (provided that all three phases are connected to the system, which is recommended, see page 27) and starts if one of them exceeds the set start current value. When the actual current in one (or several) phases exceeds the level 0.8 x set value, the display shows the warning code 200.

6.6. Relay output settings The relay outputs are configurable from the dip switch on the front panel of the master unit. See Figure 6.6-1. Switches 1 to 4 determine the latching/non latching feature of the corresponding trip relays. When a switch is turned on, latch is on for the corresponding relay, which means that the relay remains in drawn (conducting) state at an arc fault until is is reset. Switch 5 determines the function of trip relay 2. If switch 5 is in ON position, trip relay 2 will function in parallel with trip relay 1 and, in addition, trip on the BI/O trip signals from the BIO option board (if installed). See the example in Figure 6.6-3. If the switch is in OFF position, the trip relay 2 is exclusively dedicated to BI/O trip signals from the BIO option board. See Figure 2.1.2-1 and Figure 6.6-2.

Switch 6 defines the function of trip relay 3. If switch 6 is in OFF position, the trip relay 3 will function in parallel with trip relay 1. However, only local overcurrent and ARC signals will activate this stage (no BI/O lines). If the switch is ON, trip relay 3 will funcion as an CBFP relay to trip relay 1. The possible time delay settings are fast, 80, 100 or 150 ms. These must be specified when ordering. See the example in Figure 6.6-4. Switches 7 and 8 determine the function of trip relay 4. When switch 7 is turned ON, and switch 8 OFF, relay 4 becomes a trip relay which is tripping on any OC signal if a dedicated arc BIO line (Lc>) is activated (see also the function of switch 8). See Figure 6.6-5. To use relay 4 for external temperature alarm, set switch 7 in OFF position. If switch 7 and 8 both are turned ON, all trip signals will be routed to trip relay 4, which means that relay 4 will trip if one or more of the trip relays 1 ... 3 trip. See Figure 6.6-6.

6.7. Testing the arc sensors After the arc sensors have been mounted and connected to the slave units, and the system configuration has been read to the memory of the master unit, the function of the arc sensors and the data transfer between the slaves and the master unit must be tested. Before starting the testing, ensure that no trip signal will be generated when the arc sensors are activated. Tripping of the circuit-breaker can be avoided by disconnecting the circuit-breaker trip circuit, or alternatively by increasing the start value of the overcurrent subunit to a level where it cannot start in any circumstances. Verify proper operation of the sensors and the data transfer by performing the following test on each arc sensor: Expose the active part of the sensor to strong light, for instance, from an electric torch. Check that the arc sensor is activated. The TEST/ERROR indicator of the slave unit should be lit, and the address of the tested arc sensor (slave address and connector number) should appear on the display of the master unit.

NOTE! Remember to restore the trip circuits and the start value of the overcurrent unit after completing the test if changes were made.


VAMP 220 / 220R


7. Operational measures

7.1. Arc faults

7.1.1. Arc fault tripping alarm When an arc fault trip occurs, an alarm signal is obtained via the trip alarm output contact (see section 5.3.5). At the same time, the leds of the tripping relays are lit on the control panel of the master unit, thus, showing which trip outputs that were activated. In the RUN mode of the master unit, the display shows the information of the last sensor that was activated. If one or more BI/O lines were activated, the display will show the identifiers of the activated BI/O lines. To reset a trip alarm, push any button on the control panel. The trip alarm will remain active until it is reset.

7.1.2. Reading arc fault information Each time an arc sensor is activated, the address of the sensor is stored in the memory of the master unit. Up to three addresses are stored, that is, the addresses of the three sensor that last were activated. When an arc or overcurrent signal is received from a BI/O line, the identifier of the BI/O line is stored instead. To read the recorded arc fault information: 1. Enter RUN mode (if not already active) using the up and

down arrow buttons. 2. Browse through the stored codes using the left and right

push-buttons. See Figure 7.1.2-1. A sensor address is given as slave address and connector number of the sensor. The BIO lines are given by their identifiers, that is, La, Lc and Ib (see section 5.7. ) along with the word BIO. The recorded values can be erased from the memory as follows: 1. Activate the RUN mode by pushing the S button. 2. Push the E button. If the operator does not erase the display codes from the memory, they will be erased automatically within two hours.

7.2. Supervision of phase currents

7.2.1. Overcurrent warning The warning code 200 appears in the display when one or more phase currents exceed 0.8 x the start value of the overcurrent unit. The code remains on the display until all phase currents are below the mentioned limit.

7.2.2. Reading current values To read the current values measured by the overcurrent subunit: Enter the CURRENT mode using the up and down arrow but-tons. The display first shows the set start value of the overcurrent subunit. Browse to the measured phase current values (1, 2, 3) using the left and right push-buttons. See Figure 7.2.2-1.

7.3. Handling self-supervision faults

7.3.1. Error indications The self-supervision system supervises the function of the arc protection system continuously. When it detects an internal fault, an alarm signal is issued via the SF alarm contact of the master unit, and the ERROR indicator on the front panel of the master unit will remain lit to indicate an internal fault. A fault message is generated. The three last fault messages are stored in the memory of the master unit. Due to continuous selftesting of the internal circuitry, a weak rapid light pulse occurs on the ERROR indicator. This is because the test pulse is checking that the internal connections are intact, no actions need to be taken.


VAMP Ltd


7.3.2. Reading and erasing error messages To read the error messages: 1. Enter the ERROR mode using the up and down arrow

buttons. 2. Scroll through the error messages using the left and right

arrow buttons. If the internal fault can be related to one of the slave units, the address of the actual slave unit is displayed in the left display box and the fault code (see below) in the right. At general faults, e.g. communication faults, the display shows no slave address, only a fault code.

To reset the error and erase the stored fault messages: Activate the ERROR mode by pushing the S button. Push the E button. This will erase the fault message which is presently being dis-played and the next fault message will appear on the display. This again can be erased by pressing the E button, and so on. The fault messages originating from faults that have disappeared by themselves are automatically erased from the fault memory within two hours.

7.3.3. Fault codes The following table lists the fault codes with brief explanations. Below the table is a more extensive descripiton with advice about measures to take. Fault code Fault type Fault reason 10 Configuration

fault The number of sensors changed

11 Slave unit fault Faulty slave unit in the system

12 Long BIO activation

Faulty sensor or overcurrent module in the system, or setting too low

13 Communication fault

Faulty communication line

Table 7.3.3-1 Self supervision fault codes.

Fault code 10 indicates that the number of sensors in the system has changed. Sensors have been added to the system without setting the system configuration in the INSTALL mode or the connection wires of a sensor have become loose. To locate the fault, check the number of sensors of the slave unit indicated in the fault message as described in section 7.4. Check the sensor wirings of the slave unit. Fault code 11 indicates that a fault has been detected in one of the slave units of the system.

NOTE! When this fault has occurred, no activation of the sensors con-nected to the faulty slave unit will be transferred to the master unit. To locate the fault, check the connection of the modular cable of the slave unit indicated in the fault message. Check the wiring of a possible separate auxiliary power supply. Observe the indicators on the front panel. In case the green POWER indicator is off, the possible reason for the malfunction is in the auxiliary supply voltage. If the red TEST/ERROR indicator is lit without arc sensor activation, the fault is possibly either in the internal functions of the slave unit or in the sensor cables. See also the note to fault code 12 below. Fault code 12 indicates that one or more BI/O lines have been activated.


VAMP Ltd


To locate the fault, check in RUN mode which BI/O lines has been activated (see page 57). Check the wirings of the BI/O lines.

NOTE! The fault codes 11 and 12 can also be the result of an interfer-ence light detected by an arc sensor. If a sensor remains acti-vated for more than 7 seconds, the slave unit to which it is connected will be disconnected from the system. At the same time a fault alarm is given. Once the interference light disap-pears the slave unit restores its normal function and the fault alarm is reset.

NOTE! Fault code 12 can also be a result of a too low overcurrent set-ting in the alarming master unit or any master unit connected to the alarming unit via the Ib> BIO line. Fault code 13 indicates that an error has been detected in the system communication. The fault message does not include any slave unit address number. Check the modular cables and their connectors.

NOTE! In case the fault codes keep appearing after cutting the auxil-iary supply of the arc protection system, and the mentioned measures do not solve the problem, please, contact the manufacturer or his nearest representative.

7.3.4. VAM 12 CD TEST/ERROR indication The TEST/ERROR indicator of VAM 12 CD will remail lit during an internal fault of the slave unit. The master unit will show a fault code 11, see page 61 for description. The TEST/ERROR indicator will also lit up during arc sensor activation. The indicator will remain lit only the time that the sensor is detecting an arc. Due to continuous self testing of the system configuration the TEST/ERROR indicator is lit up for couple of seconds once in every 2 or 3 minutes, no actions need to be taken.


VAMP 220 / 220R


7.4. Checking system configuration The system configuration can be checked in the INFO mode of the master unit as follows: 1. Enter the INFO mode. 2. The display shows the address of a slave unit and the

number of sensors connected to it according to the system configuration done earlier.

3. Use the left and right push buttons to move between the slave units.

4. Activate the INFO mode at the desired slave unit by pushing the S push-button.

5. Push the E button to execute the check connected sensors. The display shows the number of sensors connected to the slave unit. If the shown system configuration differs from the system configuration set earlier, the difference may be due to an internal system fault.

NOTE! Checking the system configuration will not affect the configura-tion settings. If the system configuration is to be modified, it must be done in INSTALL mode. See section .
