Refer to the following sections for additional information about each I/O unit. • VAM 12L Point Sensor I/O Unit on page 35 • VAM 12LD Point Sensor I/O Unit on page 37 • VAM 10L Point Sensor I/O Unit on page 40 • VAM 10LD Point Sensor I/O Unit on page 42 • VAM 4C Current I/O Unit on page 45 • VAM 4CD Current I/O Unit on page 47 • VAM 3L Fiber Arc Sensor I/O Unit on page 50 • VAM 3LX Fiber Arc Sensor I/O Unit on page 52 VAMP 321 input/output (I/O) units are classified as either light sensor or current I/O units. The I/O units are used to connect sensors to the central unit in the VAMP 321 arc-fault detection system. Dedicated I/O units, VAM 4C and VAM 4CD, are used to measure currents from alternative locations. The I/O units provide active indication when appropriately placed inside the medium voltage enclosure. They are connected to each other using intra-unit cabling with factory-made modular cable VX001 supplied by Schnieder Electric. NOTE: During normal operation, all necessary information about the VAMP 321 system can be read from the central unit display. However, after a new installation or a system expansion, specific functions (zones and addresses, trip output, etc.) will need to be programmed into the I/O unit. For example, if an additional point sensor is added to a VAM 10L I/O unit, the Install configuration process must be repeated before the sensor addition will be recognized.

Refer to Figure 102 Pins: 1/A/2:5, 1/A/2:6 T1 Pins: 2/B/1:15, 2/B/1:16 T2 Pins: 2/B/1:17, 2/B/1:18 T3 Pins: 2/B/1:19, 2/B/1:20 T4 NOTE: If an arc fault is detected, the output closes within 7 ms when three-phase current monitoring is used. The central unit also has a general change over contact for arc fault trip circuits and a separate change over contact for self-supervision alarms. Refer to Generating Alarm Circuits on page 62 for additional information. Tripping groups are controlled using the trip relay matrix. Refer to Figure 52 for additional information. If several trip signals are required, the multiplying relay VARM 4R can be used. Generating Alarm Circuits Alarm circuits (self-supervision and trip alarms) generated by the arc-fault detection system can be forwarded to higher-level enclosure supervision and control systems through the output contacts. Connecting the Self-supervision Alarms The VAMP 321 arc-fault detection system monitors the micro controller and related circuit operation, and program execution with a separate supervision circuit. Whenever the supervision circuit detects a permanent inoperative stage in any system component, it ignores activation signals coming from that component (for example, from a detected inoperative arc sensor). The supervision circuit also monitors the internal operating voltage. For instance, if operating voltage in the central unit is lost, the system automatically gives an SF alarm since the SF output relay operates on steady-state current. In other words, the SF relay is actuated when the operating voltage is on and within the permitted limits. The self-supervision system also issues a self-supervision alarm when it detects an incorrect number of sensors. It is advised to connect the SF output to an appropriate annunciating unit in the substation. Connect the self-supervision alarm output to an SF change-over contact using the following pins.

Disconnecting the secondary circuit of a live current transformer may cause dangerous overvoltages. Failure to follow these instructions will result in death or serious injury. Connect the secondary circuits of the current transformers to the following screw connectors: • X1-1, X1-3 (L1) • X1-5, X1-7 (L2/I0) • X1-9, X1-11 (L3) The arc detection system can also be single or two-phase connected. Three-phase connection is nevertheless recommended for optimal operating speed. The current measuring channels L1 and L3 must be used in connection with two-phase current measuring. Single-phase current or ground fault current must always be connected to the current measuring channel L2/I0; otherwise, an unbalance error will occur. The specified operating time introduced in the Technical data on page 176 can only be guaranteed for three-phase current measurement and with the proper voltage supply to all system components, minimum allowed auxiliary voltage measured at I/O unit's terminals is 21.6 Vdc. The VAM 4C overcurrent unbalance alarm settings recognizes if the two-phase or three-phase monitoring is being used based on the connections made to the unit and the overcurrent limits set for each connection. The two-phase connection monitoring is triggered when the L2/I0 connection overcurrent limit differs from the L1/L3 overcurrent limit settings by 90% or more. This is because in the event two-phase monitoring is used, the L2/I0 connection is the connection used to monitor the ground current. Therefore, the current limit set for the L2/I0 connection should reflect limits associated with anticipated ground currents. The remaining L1/L3 currents should be balanced, and overcurrent settings for the L1/L3 connection should be reflected as such. The two-phase monitoring mode is also referred to as “ground-fault mode.” The three-phase monitoring is triggered when the L2/I0 and L1/L3 overcurrent limit settings are similar, reflecting that each phase is understood to be in balance with the other two phases. If detected, the system gives an unbalance alarm after a 10-second delay time. The alarm does not affect other operations of the arc detection system. The phase discontinuity settings are non-adjustable since all the setting values have been programmed in the current-monitoring unit. 72 © 2014 Schneider Electric All rights reserved 63230-218-204 12/2014 VAMP 321 Arc-fault Detection System for Medium Voltage Applications Section 4— Installation, Wiring and Functionality Connecting the trip circuits of the circuit breakers ENGLISH Connect the circuit breaker’s trip circuit to the following pins: TRIP1: X2-15, X2-16 For example, in the event of an arc fault, the output contact will close at specified time when three-phase current measurement is used. The output trip relay of the light I/O units (VAM 10L and VAM 3 L) operates during faults in its own zone. In the current I/O unit (VAM 4 C), select the detection zone controlling the I/O unit using the programming switches. If several trips are required, the multiplying relay VAMP 4R can be used. If VAMP 4R is used, make sure that proper voltage supply is connected to device. Connecting between the central unit and the I/O unit HAZARD OF EQUIPMENT DAMAGE Connect the central unit to the I/O units with a modular cable of type VX001. The modular cable carries all information between the central unit and I/O units, including data in serial form, arc fault messages and operating supply to the I/O units. Do not connect modular cables closed loop. • Connect the VX001 cable to the arc I/O COM interface of the central units. Failure to follow these instructions can result in personal injury or equipment damage. • Connect the cable to COM1 or COM2 on the first I/O unit. • Route the cable from COM1 or COM2 on the first I/O unit to COM1 or COM2 in the next unit, etc. CAUTION All the COM1 and COM2 interfaces are identical, i.e. the cable can always be connected to either interface. The maximum total length of the modular cable, taking into account all the I/O units connected to the central unit, is 328.10 ft (100 m). NOTE: Use only star connection for I/O units. Maximum single bus cable length is 98 ft (30 m). © 2014 Schneider Electric All rights reserved 73 VAMP 321 Arc-fault Detection System for Medium Voltage Applications Section 4— Installation, Wiring and Functionality 63230-218-204 12/2014 Connecting separate auxiliary supplies ENGLISH When routing modular cables over long distances (98.43 ft of modular cabling) or when the system contains more than 4 I/O units you should preferably use a separate auxiliary +24Vdc voltage supply with output monitoring along with the modular bus cabling. Recommended types of power supplies with output monitoring: 1. Phaseo ABL4RSM24035 (3.5A @ 24Vdc) 2. Phaseo ABL4RSM24050 (5A @ 24Vdc) 3. or any equivalent type of power supply with above functionality NOTE: Use of power supplies without voltage monitoring is not recommended. Connect the auxiliary supply to the 24 V terminals of the last I/O unit. Use at least 1.5mm2 (AWG 16) size twisted pair cable. NOTE: It is recommended to use external wiring to connect auxiliary supply to all units. Pay particular attention to the polarity of the wire and cable connections.

If arc point sensors are used in open compartments, such as busbar sections, sensors should be placed at a minimum every 9.85 ft (3 m) in the compartments. The mounting position is not critical because of the wide sensor detection range and the light reflection inside the enclosure. Figure 43: VA 1 DA Point Arc Sensor Sensitivity Refer to Figure 44. To install the VA 1 DA point arc sensors onto the outside enclosure wall: Push the active part of the sensor through the 0.39 in. (10 mm) hole in the wall. Secure it using a #8 (4 mm) screw. To surface-mount the VA 1 DA point sensors to the wall: Install mounting plates VYX002 or VYX001. Order brackets separately (not included with the arc sensor). Refer to Figure 45 and Figure 46.

Do not mount the sensors directly under a light source. If the sensor is exposed to a light exceeding pick-up criteria (8000 lx) for over 3 seconds the sensor channel is blocked. It will become operational again once the light source is removed. Before final commissioning: • Verify that the surrounding light sources near the point arc sensors do not activate the sensors’ channel. • Consider light exposure with and without doors closed and possible maintenance or inspection. The rear of the point arc sensors can also detect sources of light. Connecting the VA 1 DA Point Arc Sensors to the I/O Units The sensors are equipped with the standard 19.69 ft (6m) cable or a 64.36 ft (20m) shielded cable (to be specified in the order). After mounting the sensors, connect them to the I/O units as follows: © 2014 Schneider Electric All rights reserved 1. Determine suitable cable length using the shortest route possible to the nearest I/O unit. 2. Cut the wire at the length determined in step 1. 3. Connect the arc sensors to the screw pins X1:1 – X1:20. The arc sensors’ cable polarity is not critical. 4. Cables should be in LV compartment (only required part the primary area) as far from from the primary bus bars and cables as possible. 77 VAMP 321 Arc-fault Detection System for Medium Voltage Applications Section 4— Installation, Wiring and Functionality 63230-218-204 12/2014 VAMP 4R Multiplying Relay ENGLISH Installing the VAMP 4R The multiplying relay VAMP 4R can be used when additional trip outputs are needed.

For example each start-on, start-off, trip-on or trip-off of any detection stage has a unique event number code. Such a code and the corresponding time stamp is called an event. As an example of information included with a typical event a programmable stage trip event is shown in the following table. EVENT Description Local panel Communication protocols Code: 46E2 Channel 46, event 2 Yes Yes Prg1 trip on Event text Yes No 0.41 x In Fault value Yes No 2007-01-31 Date Yes Yes 08:35:13.413 Time Yes Yes Events are the major data for a SCADA system. SCADA systems are reading events using any of the available communication protocols. Event log can also be scanned using the front panel or using VAMPSET. With VAMPSET the events can be stored to a file especially in case the relay is not connected to any SCADA system. Only the latest event can be read when using communication protocols or VAMPSET. Every reading increments the internal read pointer to the event buffer. (In case of communication interruptions, the latest event can be reread any number of times using another parameter.) On the local panel scanning the event buffer back and forth is possible. Event enabling/masking In case of an uninteresting event, it can be masked, which prevents the particular event(s) to be written in the event buffer. As a default there is room for 200 latest events in the buffer. Event buffer size can be modified from 50 to 2000. Modification can be done in “Local panel conf” –menu. Indication screen (popup screen) can also be enabled in this same menu when VAMPSET –setting tool is used. The oldest one will be overwritten, when a new event does occur. The shown resolution of a time stamp is one millisecond, but the actual resolution depends of the particular function creating the event. For example most detection stages create events with 5ms, 10 ms or 20 ms resolution. The absolute accuracy of all time stamps depends on the time synchronizing of the relay. See System clock and synchronization on page 90 for system clock synchronizing. Event buffer overflow The normal procedure is to poll events from the device all the time. If this is not done then the event buffer could reach its limits. In such case the oldest event is deleted and the newest displayed with OVF code in HMI. - © 2014 Schneider Electric All rights reserved 85 ENGLISH Supporting functions VAMP 321 Arc-fault Detection System for Medium Voltage Applications Section 4— Installation, Wiring and Functionality 63230-218-204 12/2014 Table 35: Setting parameters for events ENGLISH Parameter Value Description Count Note Number of events ClrEn - Clear event buffer Set Order of the event buffer for local display Set Scaling of event fault value Set Clear Order Old-New New-Old FVSca PU Per unit scaling Pri Primary scaling Display On Indication dispaly is enabled Alarms Off No indication display Set FORMAT OF EVENTS ON THE LOCAL DISPLAY Code: CHENN CH = event channel, NN=event code Event description Event channel and code in plain text yyyy-mm-dd Date (for available date formats, see System clock and synchronization on page 90) hh:mm:ss.nnn Time Disturbance recorder The disturbance recorder can be used to record all the measured signals, that is, currents, voltage and the status information of digital inputs (DI) and digital outputs (DO). The digital inputs also include the arc detection signals. Triggering the recorder The recorder can be triggered by any start or trip signal from any detection stage or by a digital input. The triggering signal is selected in the output matrix (vertical signal DR). The recording can also be triggered manually. All recordings are time stamped. Reading recordings The recordings can be uploaded, viewed and analysed with the VAMPSET program. The recording is in COMTRADE format. This also means that other programs can be used to view and analyse the recordings made by the relay. For more details, please see a separate VAMPSET manual. Number of channels 86 At the maximum, there can be 12 recordings, and the maximum selection of channels in one recording 12 (limited in wave form) and digital inputs reserve one channel (includes all the inputs).

The system clock should be externally synchronised to get comparable event time stamps for all the relays in the system. The synchronizing is based on the difference of the internal time and the synchronising message or pulse. This deviation is filtered and the internal time is corrected softly towards a zero deviation. Time zone offsets Time zone offset (or bias) can be provided to adjust the local time for IED. The Offset can be set as a Positive (+) or Negative (-) value within a range of -15.00 to +15.00 hours and a resolution of 0.01/h. Basically quarter hour resolution is enough. Daylight saving time (DST) - IED provides automatic daylight saving adjustments when configured. A daylight savings time (summer time) adjustment can be configured separately and in addition to a time zone offset. Daylight time standards vary widely throughout the world. Traditional daylight/summer time is configured as one (1) hour positive bias. The new US/Canada DST standard, adopted in the spring of 2007 is: one (1) hour positive bias, starting at 2:00am on the second Sunday in March, and ending at 2:00am on the first Sunday in November. In the European Union, daylight change times are defined relative to the UTC time of day instead of local time of day (as in U.S.) European customers, please carefully find out local country rules for DST. The daylight saving rules for Finland are the IED defaults (24-hour clock): - Daylight saving time start: Last Sunday of March at 03.00 - Daylight saving time end: Last Sunday of October at 04.00 To ensure proper hands-free year-around operation, automatic daylight time adjustments must be configured using the “Enable DST” and not with the time zone offset option. 90 © 2014 Schneider Electric All rights reserved VAMP 321 Arc-fault Detection System for Medium Voltage Applications Section 4— Installation, Wiring and Functionality Adapting auto adjust During tens of hours of synchronizing the device will learn its average deviation and starts to make small corrections by itself. The target is that when the next synchronizing message is received, the deviation is already near zero. Parameters "AAIntv" and "AvDrft" will show the adapted correction time interval of this ±1 ms auto-adjust function. Time drift correction without external sync If any external synchronizing source is not available and the system clock has a known steady drift, it is possible to roughly correct the clock deviation by editing the parameters "AAIntv" and "AvDrft". The following equation can be used if the previous "AAIntv" value has been zero. AAIntv = 604.8 DriftInOneWeek If the auto-adjust interval "AAIntv" has not been zero, but further trimming is still needed, the following equation can be used to calculate a new auto-adjust interval. AAIntvNEW = 1 AAIntvPREVIOUS 1 DriftInOneWeek + 604.8 The term DriftInOneWeek/604.8 may be replaced with the relative drift multiplied by 1000, if some other period than one week has been used. For example if the drift has been 37 seconds in 14 days, the relative drift is 37*1000/(14*24*3600) = 0.0306 ms/s. Example 1 If there has been no external sync and the relay's clock is leading sixty-one seconds a week and the parameter AAIntv has been zero, the parameters are set as AvDrft = Lead AAIntv = 604.8 = 9. 9 s 61 With these parameter values the system clock corrects itself with –1 ms every 9.9 seconds which equals –61.091 s/week. Example 2 If there is no external sync and the relay's clock has been lagging five seconds in nine days and the AAIntv has been 9.9 s, leading, then the parameters are set as AAIntv NEW = 1 = 10.6 1 5000 − 9.9 9 ⋅ 24 ⋅ 3600 AvDrft = Lead If there is no external sync and the relay's clock has been lagging five seconds in nine days and the AAIntv has been 9.9 s, leading, then the parameters are set as When the internal time is roughly correct – deviation is less than four seconds – any synchronizing or auto-adjust will never turn the clock backwards. Instead, in case the clock is leading, it is softly slowed down to maintain causality. © 2014 Schneider Electric All rights reserved 91 ENGLISH 63230-218-204 12/2014 VAMP 321 Arc-fault Detection System for Medium Voltage Applications Section 4— Installation, Wiring and Functionality 63230-218-204 12/2014 Table 37: System clock parameters ENGLISH Parameter Value Unit Description Note Date Current date Set Time Current time Set Date format Set Style SyncDI TZone y-d-m Year-Month-Day d.m.y Day.Month.Year m/d/y Month/Day/Year Possible values depends on the types of I/O cards The digital input used for clock synchronisation. - DI not used for synchronizing -15.00 – +15.00 *) UTC time zone for SNTP synchronization. ***) Set Note: This is a decimal number.

Sync source is selected with SyncDI setting. When rising edge is detected from the selected input, system clock is adjusted to the nearest minute. Length of digital input pulse should be at least 50 ms. Delay of the selected digital input should be set to zero. Synchronisation correction If the sync source has a known offset delay, it can be compensated with SyOS setting. This is useful for compensating hardware delays or transfer delays of communication protocols. A positive value will compensate a lagging external sync and communication delays. A negative value will compensate any leading offset of the external synch source. Sync source When the device receives new sync message, the sync source display is updated. If no new sync messages are received within next 1.5 minutes, the device will change to internal sync mode. Sync source: IRIG-B003 IRIG-B003 synchronization is supported with a dedicated communication option with either a two-pole or two pins in a D9 rear connector (See Order information on page 187). IRIG-B003 input clock signal voltage level is TLL. The input clock signal originated in the GPS receiver must be taken to multiple relays trough an IRIG-B distribution module. This module acts as a centralized unit for a point-to-multiple point connection. Note: Daisy chain connection of IRIG-B signal inputs in multiple relays must be avoided.

Time deviation is calculated after receiving new sync message. The filtered deviation means how much the system clock was really adjusted. Filtering takes care of small deviation in sync messages. Auto-lag/lead The device synchronizes to the sync source, meaning it starts automatically leading or lagging to stay in perfect sync with the master. The learning process takes few days. Non-volatile RAM The non-volatile RAM of the device is implemented using a super capacitor and a RAM memory with low power consumption. When auxiliary power is on the super capacitor is charged from the internal power supply of the device and the non-volatile RAM memory also gets power from the same source. When auxiliary power is turned off the RAM memory is powered by the super capacitor. The memory will keep its contents as long as there is enough voltage in the super capacitor. This time is 7 days in +77°F room temperature – high humidity will decrease the time. The non-volative RAM is used to store the disturbance recordings and the event-buffer. 94 © 2014 Schneider Electric All rights reserved 63230-218-204 12/2014 VAMP 321 Arc-fault Detection System for Medium Voltage Applications Section 4— Installation, Wiring and Functionality The functions of the microcontroller and the associated circuitry, as well as the program execution are supervised by means of a separate watchdog circuit. Besides supervising the relay, the watchdog circuit attempts to restart the micro controller in an inoperable situation. If the micro controller does not resart, the watchdog issues a self-supervision signal indicating a permanent internal condition. When the watchdog circuit detects a permanent fault, it always blocks any control of other output relays (except for the self-supervision output relay and the output relays used in the arc detection function). The condition of the VAMP 321 central unit, the I/O units and the sensors are supervised. Events are generated when possible problems occur or disappear. The events are stored in the IED event buffer and they can be read on the local HMI or VAMPSET. Channel, events codes and situations where events are generated: 134E1 - 134E10: Arc sensor 1 - 10 not conn. improper connection ON 134E11 - 134E20: Arc sensor 1 - 10 not conn. improper connection OFF 134E21 - 134E30: Arc sensor 1 - 10 short circuit ON 134E31 - 134E40: Arc sensor 1 - 10 short circuit OFF 134E41 - 134E50: Arc sensor 1 - 10 daylight detected ON 134E51 - 134E60: Arc sensor 1 - 10 daylight detected OFF 135E1: I/O unit sensor improper connection ON (I/O unit + sensor number also shown) 135E2: I/O unit sensor improper connection OFF (I/O unit + sensor number also shown) 135E3: I/O unit ArcI/O bus C interruption ON (I/O unit number also shown) 135E4: I/O unit ArcI/O bus C interruption OFF (I/O unit number also shown) 135E9: I/O unit ArcI/O bus R interruption ON (I/O unit number also shown) 135E10: I/O unit ArcI/O bus R interruption OFF (I/O unit number also shown) Communication interruption between the VAMP 321 and I/O units is also shown by “Arc I/O bus signal” in the output matrix and logics. Only some of the communication protocols (IEC 61850, SPA-bus, Modbus and ModbusTCP) have capability to transfer all of these events. In some protocols only a selected subset can be left off or only status of COM5 is available with the help of logic programming. Diagnostics The device runs self-diagnostic tests for hardware and software in boot sequence and also performs runtime checking. Permanent inoperative state If permanent inoperative state has been detected, the device releases SF relay contact and status LED is set on. Local panel will also display a detected fault message. Permanet inoperative state is entered when the device is not able to handle main functions. Temporal inoperative state When self-diagnostic function detects a temporal inoperative state, Selfdiag matrix signal is set and an event (E56) is generated. In case the inoperative state was only temporary, an off event is generated (E57). Self diagnostic state can be reset via local HMI. Diagnostic registers There are four 16-bit diagnostic registers which are readable through remote protocols.

Trip contacts can be controlled by using relay output matrix or logic function. Also forced control is possible. When using force controlling it has to be first enabled in the “relays” menu. The output relays are also called digital outputs. Any internal signal can be connected to the output relays using "OUTPUT MATRIX" and/or "ARC MATRIX - OUTPUT". An output relay can be configured as latched or non-latched. The position of the contact can be checked in “output matrix” and “relays” menu. An output relay can be configured as latched or non-latched. Latched relay contacts can be set free by pressing the “enter” key of the IED or by releasing from VAMPSET setting tool. The difference between trip contacts and alarm contacts is the DC breaking capacity. The contacts are single pole single throw (SPST) normal open type (NO), except alarm relay A1 which has change over contact single pole double throw (SPDT). Figure 55: Trip contacts can be connected to detection stages or other similar purpose in “output matrix” menu. Figure 56: Trip contacts can be assigned directly to outputs of logical operators.

The rated voltage of these signals is 30 V dc when active. The input signal has to be 18 – 250 V dc to be activated. Binary inputs The binary inputs (BI) can be used to get the light indication from another IED to build selective arc detection systems. BI is a dry input for 18 – 250 V dc signal. The connection of BI signals is configured in the matrices of the arc flash detection function. Binary output The binary outputs (BO) can be used to give the light indication signal or any other signal or signals to another IED's binary input to build selective arc detection systems. BO is an internally driven (wetted) 30 Vdc signal. The connection of BO signals is configured in the matrices of the arc flash detection function. Virtual inputs and outputs There are virtual inputs and virtual outputs, which can in many places be used like their hardware equivalents except that they are only located in the memory of the device. The virtual inputs acts like normal digital inputs. The state of the virtual input can be changed from local display, communication bus and from VAMPSET. For example setting groups can be changed using virtual inputs. Virtual inputs can be used in many operations. The status of the input can be checked in “output matrix” and “virtual inputs” menu. Status is also visible on local mimic display if so selected. Virtual inputs can be selected to be operated trough function buttons F1 and F2, trough local mimic or simply by using the virtual input menu. Virtual inputs makes possible to change group, block/enable/disable functions, to program logics and other similar to digital inputs. Activation and reset delay of input is approximately 5ms.

There are general purpose LED indicators – "A", "B", "C" to ”N” – available for customer-specific indications on the front panel. Their usage is define in a separate LED MATRIX. Furthermore there are two LED indicators specified for keys F1 and F2. In addition, the triggering of the disturbance recorder (DR) and virtual outputs are configurable in the output matrix. See an example in Figure 70. Figure 70: Output matrix An output relay or indicator LED can be configured as latched or non-latched. A non-latched relay follows the controlling signal. A latched relay remains activated although the controlling signal releases. Figure 71: Release output matrix latches There is a common "release all latches" signal to release all the latched relays. This release signal resets all the latched output relays and indicators with CPU and FPGA control. The reset signal can be given via a digital input, via HMI or through communication. The selection of the input is done with the VAMPSET software under the menu "Release output matrix latches". See an example in Figure 71.

Controlling can be done by "select-execute" or "direct control" principle. The object block matrix and logic functions can be used to configure interlocking for a safe controlling before the output pulse is issued. The objects 1 – 6 are controllable while the objects 7 – 8 are only able to show the status. Controlling is possible by the following ways: • through the local HMI • through a remote communication • through a digital input • through the function key The connection of an object to specific output relays is done via an output matrix (object 1 – 6 open output, object 1 – 6 close output). There is also an output signal “Object failed”, which is activated if the control of an object is not completed. Object states Each object has the following states: Setting Value Object state Description Undefined (00) Actual state of the object Open Close Undefined (11) Basic settings for controllable objects Setting DI for ‘obj open’ Each controllable object has the following settings: Value Description None, any digital input, virtual input or virtual output Open information DI for ‘obj close’ Close information DI for ‘obj ready’ Ready information Max ctrl pulse length 0.02 – 600 s Pulse length for open and close commands Completion timeout 0.02 – 600 s Timeout of ready indication Object control Open/Close Direct object control If changing states takes longer than the time defined by “Max ctrl pulse length” setting, object is inoperative and “Object failure” matrix signal is set. Also undefined-event is generated. “Completion timeout” is only used for the ready indication. If “DI for ‘obj ready’” is not set, completion timeout has no meaning. Output signals of controllable objects Each controllable object has 2 control signals in matrix: Output signal Description Object x Open Open control signal for the object Object x Close Close control signal for the object These signals send control pulse when an object is controlled by digital input, remote bus, auto-reclose etc. © 2014 Schneider Electric All rights reserved 111 ENGLISH Controllable objects VAMP 321 Arc-fault Detection System for Medium Voltage Applications Section 4— Installation, Wiring and Functionality Settings for read-only objects ENGLISH Setting DI for ‘obj open’ Each read-only object has the following settings: Value None, any digital input, virtual input or virtual output DI for ‘obj close’ Object timeout 63230-218-204 12/2014 Description Open information Close information 0.02 – 600 s Timeout for state changes If changing states takes longer than the time defined by “Object timeout” setting, and “Object failure” matrix signal is set.

Local/Remote selection In Local mode, the output relays can be controlled via a local HMI, but they cannot be controlled via a remote serial communication interface. In Remote mode, the output relays cannot be controlled via a local HMI, but they can be controlled via a remote serial communication interface. The selection of the Local/Remote mode is done by using a local HMI, or via one selectable digital input. The digital input is normally used to change a whole station to a local or remote mode. The selection of the L/R digital input is done in the “Objects” menu of the VAMPSET software. A password is not required for a remote control operation. Controlling with DI Objects can be controlled with digital input, virtual input or virtual output. There are four settings for each controllable object: Setting Active DI for remote open / close control In remote state DI for local open / close control In local state If the device is in local control state, the remote control inputs are ignored and vice versa. Object is controlled when a rising edge is detected from the selected input.

Some measurement values are shown as relative values - per unit or percent. The scaling is done using the given CT, VT values. The following scaling equations are useful when doing secondary testing. Current scaling The rated value of the device's current input, for example 5 A or 1A, does not have any effect in the scaling equations, but it defines the measurement range and the maximum allowed continuous current. See Table 71 for details.

An external VPA 3CG and VX072 cables are required. Device profile "continuous mode" In this mode, the device is sending a configured set of data parameters continuously to the Profibus DP master. The benefit of this mode is the speed and easy access to the data in the Profibus master. The drawback is the maximum buffer size of 128 bytes, which limits the number of data items transferred to the master. Some PLCs have their own limitation for the Profibus buffer size, which may further limit the number of transferred data items. Device profile "Request mode" Using the request mode it is possible to read all the available data from the VAMP device and still use only a very short buffer for Profibus data transfer. The drawback is the slower overall speed of the data transfer and the need of increased data processing at the Profibus master as every data item must be separately requested by the master. NOTE: In request mode, it is not possible to read continuously only one single data item. At least two different data items must be read in turn to get updated data from the device. There is a separate manual for VPA 3CG (VVPA3CG/EN M/xxxx) for the continuous mode and request mode. The manual is available to download from our website. Available data VAMPSET will show the list of all available data items for both modes. A separate document “Profibus parameters.pdf” is also available. The Profibus DP communication is activated usually for remote port via a menu selection with parameter "Protocol". See Communication ports on page 130.

The unbalanced transmission mode of the protocol is used, and the device functions as a secondary station (slave) in the communication. Data is transferred to the primary system using "data acquisition by polling"-principle. The IEC functionality includes application functions: • station initialization • general interrogation • clock synchronization and • command transmission. It is not possible to transfer parameter data or disturbance recordings via the IEC 103 protocol interface. The following ASDU (Application Service Data Unit) types will be used in communication from the device: The device will accept: The data in a message frame is identified by: • ASDU 1: time tagged message • ASDU 3: Measurands I • ASDU 5: Identification message • ASDU 6: Time synchronization and • ASDU 8: Termination of general interrogation. • ASDU 6: Time synchronization • ASDU 7: Initiation of general interrogation and • ASDU 20: General command. • type identification • function type and • information number. These are fixed for data items in the compatible range of the protocol, for example, the trip of I> function is identified by: type identification = 1, function type = 160 and information number = 90. "Private range" function types are used for such data items, which are not defined by the standard (e.g. the status of the digital inputs and the control of the objects). The function type and information number used in private range messages is configurable. This enables flexible interfacing to different master systems.

The system accommodates up to 16 I/O units. Eight (8) addresses are reserved for each detection zone: • Zone 1 addresses 0 – 7 • Zone 2 addresses 8 – 15 • Zone 3 addresses 16 – 23 • Zone 4 addresses 24 – 31 I/O Unit Address Creation and Assignment The programming switches have different weighted coefficients. To create an address for the I/O unit: 1. Turn switches with different values to the ON position. 2. Calculate the sum of their weighted coefficients. The following table shows the weighted coefficients of each programming switch. Table 66: Programming Switch Weighted Coefficients 1 Switch No. Weighted Coefficients 8 1 7 2 6 4 5 8 41 16 VAM 12L / VAM 12LD, VAM 10L / VAM 10LD, VAM 3L and VAM 3LX only The address range for current I/O units is (32), 33 – 46 (Zone 5). NOTE: Do not use address 32. In this case, the current I/O unit operates in Central Unit mode, and the actual central unit must be set to Sub-Unit mode. To determine the address of a current I/O unit, add the sum of the weighted coefficients to 32. Example Programming switch values total 7, address of the current I/O unit is 32: (32 + 7 = 39). NOTE: Do not use 32 as the unit address if system has a central unit.

Decommissioning WARNING DECOMISSIONING OF ARC DETECTION SYSTEM Turn off all power during decommissioning activities. Use properly rated voltage detector to confirm power is off. Failure to follow these instruction can result in death or serious injury. In case the commissioned system requires decommissioning where system components are changed or removed make sure that the switchgear to be protected is turned off. Make sure that the switchgear is restored back to its original construction if arc detection components are removed from the gear. Pay attention that possible holes, and cut-outs are not left in the switchgear. © 2014 Schneider Electric All rights reserved 161 VAMP 321 Arc-fault Detection System for Medium Voltage Applications Section 6— Configuring, Commissioning and Maintaining VAMP 321 63230-218-204 12/2014 Maintenance ENGLISH The VAMP 321 IED and its extension units require maintenance in order to work according to specification. Keep record of the maintenance actions performed for the system. The maintenance can include, but is not limited the following actions. Preventative maintenance The VAMP 321 IED and its extension units, sensor and cabling shall be visually checked when the switchgear is de-energized. During such inspection pay attention to • possible dirty arc sensors • loose wire connections • damaged wiring • indicator lights ( see section LED test sequence) and • other mechanical connections. Visual inspection shall be made maximum every three (3) years. Periodical testing The IED and its satellite extension units, cabling and sensors must periodically be tested according to the end-user's safety instructions, national safety instructions or law. Manufacturer recommend functional testing being carried minimum every five (5) years. It is proposed that the periodic testing is conducted with a secondary injection principle for those detection stages which are used in the IED and its extension units. Follow separate testing manual (VARCTEST/EN/M_xxxx) for a test protocol. Cleaning of hardware Special attention must be paid that the IED, it's extension units and sensors do not become dirty. In case cleaning is required, wipe out dirt from the units. Sensor condition and positioning check After commissioning, sensor replacement, modification procedure, cleaning and periodical testing always check that the sensor positioning remains as it was originally designed. System status messages In case IED's self checking detects unindented system status it will in most of the cases provide alarm concerning this by activating the Service LED and indication status notification on the LCD screen. Should this happen store the possible message and contact your local representative for further guidance. Spare parts Use entire unit as a spare for the device to be replaced. Always store spare parts in storage areas that meet requirements stated in Test and environmental conditions on page 180. 162 © 2014 Schneider Electric All rights reserved 63230-218-204 12/2014 VAMP 321 Arc-fault Detection System for Medium Voltage Applications Section 7— Block Diagrams and Connection Examples VAMP 321 Central Unit Block Diagram NOTE: The examples and diagrams in the following pages are for illustrative purposes only and may not meet each customer’s specific application requirements.

Each VAM 12L and VAM 12LD I/O unit is comprised of three (3) electromechanical trip Normally Open (NO) contacts and one (1) trip alarm change-over contact. Refer to Figure 114. In this example, by setting L>int/ext to ext mode, all three (3) trip outputs will trip for a fault in zone, which will also isolate outgoing feeders for a fault in the busbar compartment.

VAMP 321 Arc-fault Detection System for Medium Voltage Applications multizone arc flash detection system Figure 115: VAMP 321 application example. T3 CBFP ZONE 1 = Arc Sensor VAMP 321 Central Unit T, T1, T2, T3 = Trip Zone A Cable compartment of the incoming feeder Zone B Circuit-breaker compartment Zone 1 Busbar compartment ZONE 2 ZONE 3 Zone1.1/ Combined circuit-breaker and cable Zone 1.2 termination compartment ZONE 4 © 2014 Schneider Electric All rights reserved I/O unit ZONE 5 173 ENGLISH Section 8— Application Examples VAMP 321 Arc-fault Detection System for Medium Voltage Applications Section 8— Application Examples 63230-218-204 12/2014 Functional description ENGLISH In this application example, the arc flash sensor for zone 1.1 is connected to the I/O unit input number 1. If the arc flash sensor awakens and simultaneously VAMP 321 sends a current signal to the I/O unit, the zone 1.1 is isolated by the outgoing feeder breaker. The arc flash sensor for zone 1.2 is connected to the I/O unit input number 2 or 3. If the arc flash sensor awakens and simultaneously VAMP 321 sends a current signal to the I/O unit, the zone 1.2 is isolated by the outgoing feeder breaker. The arc flash sensors for zone 1 are connected to the I/O unit sensor channels 4 – 10. If a sensor awakens in zone 1, the light-only signal is transferred to VAMP 321 which then trips the main circuit breaker. NOTE: For 12L and 12LD units, three sensor channels can trip their own zone independently, the other seven sensor channels can be allocated to another zone. The sensor S2 connected to VAMP 321 in zone B overlaps zone A. If the circuit breaker fails to isolate the failure in zone B, the sensor (S2) generates a time-delayed circuit-breaker failure protection trip to the upstream breaker. The incoming feeder circuit breaker has a CBFP backup trip to the upstream breaker. If zone 1 trip (T1) fails, the CBFP takes over and trips the upstream circuit breaker. Zone A illustrates a typical medium voltage incoming feeder where the current transformers are located after the cable termination. In this case, an eventual arc flash fault in the cable termination does not activate the current element in VAMP 321. However, arc detection can be achieved by using the light-only principle. If an arc flash occurs in cable termination, zone A is tripped by an upstream circuit breaker. The sensor S1 in zone A overlaps the incoming circuit breaker. Zone A operates on light-only principle as the currents are not available for current and light operation. The circuit-breaker failure protection (CBFP) protects in case there is a detected failure in zone 1, or in sensor S2 in zone B. The trip output (T2/CBFP) can function as a trip output, but also as a time-delayed circuit-breaker failure protection. To enable CBFP, an additional time-delayed stage needs to be created.
