2 Introduction

This User’s Manual contains a functional description of the VAM I/Ounits and technical data.

2.1 PurposeThe main purpose of the VAM I/O units is to detect arc light or shortcircuit current and deliver this information (zone information) to thearc protection central unit and the other VAM I/O units. AdditionallyVAM I/O units can be used for tripping appropriate circuit breakers.

This document is not applicable in North American market.

2.2 Main propertiesArc flash protection system is a modular system consisting of acentral unit, I/O units and arc sensors.

Due to its modularity, the system is suitable for a range of arcprotection applications, from simple systems with one central unitand one I/O unit to more complex solutions comprising several centralunits used for selective arc protection.

The I/O unit VAM 10L / VAM 10LD, VAM 12L / VAM 12LD servesas link between the system’s point sensors and the central unit. EachI/O unit has connections for ten arc sensors, one portable pin sensorand one trip output.

The I/O unit VAM 3L/VAM3LX serves as link between the system’sfibre sensors and the central unit. Each I/O unit has connections forthree arc sensors, one pin sensor and one trip output.

The I/O unit VAM 4C / VAM 4CD serves as link between the system’scurrent inputs and the central unit. Each I/O unit has connections forthree current transformers and one trip output.

The arc sensor VA 1 DA is activated by strong light. The sensortransforms the light information into the current signal, which isforwarded through the I/O unit to the central unit. The arc sensor VA1 EH also operates on the same principle.

The pin sensor VA 1 DP has the same functions as an arc sensorbut can be temporarily connected to an I/O unit. The sensor can befixed to the breast pocket of a technician to improve safety whenworking with live switchgear.

VIO/en M/A0038

2 Introduction

The door mounted VAM I/O units with the letter D in the typedesignations VAM 10LD, VAM 12LD and VAM 4CD are door mountedversions for the corresponding VAM 10L, VAM 12 L and VAM 4Cunits. The functionality is exactly the same.

2.2 Main properties2 Introduction

3 User interface

Usually, there is no need to touch the front panel during normaloperation, since all the necessary information can be read from thecentral unit display. However, after a new installation or a systemexpand you will need to program certain functions (zone/address,trip output) in the I/O unit.

NOTE: If you unfasten the terminal blocks during installation, remember totighten the fixing screws after installation! Also tighten the screwseven if you did not unfasten the blocks.

4 Programming switches

Before system implementation, check the positions of theprogramming switches in accordance with the following basicprinciples:

• Each I/O unit connected to the communication bus has its ownaddress (each I/O unit have an unique address).

• Set the programming switches before connecting the supplyvoltage.

• If you have to change the switch positions once the supplyvoltage has been connected, disconnect the supply voltage tothe unit in question for the duration of the programming andre-configure the system.

• If position of the switch is changed, re-install the system againin the central unit.

4.1 Switches for arc sensor I/O unitsThe programming switches of the I/O units are used to determinethe unit address and trip relay function.

The system accommodates up to 16 units. Eight addresses arereserved for each protection zone:

• Zone 1 addresses 0 – 7• Zone 2 addresses 8 – 15• Zone 3 addresses 16 – 23• Zone 4 addresses 24 – 31

The programming switches have different weight factors. To createan address for the I/O unit, turn switches with different values to theON position and calculate the sum of their weight factors. Thefollowing table shows the weight factors of each programming switch.Table 4.1: Programming switch weight factors, *) VAM 10L / VAM 10LD, VAM12L / VAM 12LD, and VAM 3L / VAM 3LX only

Switch 1 determines which light activation activates the arc stage.When the switch position is ON, the arc stage only activates on thelight information provided by the unit's own sensors. In OFF positionthe arc stage activates on the light information received from anyunit in the same protection zone.

Switch 2 determines the trip relay latch. When the switch is in ONposition the trip relay remains engaged after the arc trip until the faultis acknowledged at the central unit’s panel. In the OFF position thetrip relay follows the arc fault.

Switch 3 determines the arc trip criteria. When the switch is in ONposition the trip is based on light information only; in OFF positionboth fault currents exceeding the current limit and light informationare required.

4.1 Switches for arc sensor I/O units4 Programming switches

VAM 12L / VAM 12LD

When the L>ext/int DIP switch is in “L>int” position, the output relaysare only activated by dedicated sensors.

SENSOR 1 activates T1.



SENSORS 4 to 10 are normally sending light information to systemaccording to zone setting.

If the switch is in “L>ext” position, all output relays are also controlledby the selected zone information. This activation source can be anysensor channel 4 to 10 or from an external I/O unit configured to thesame zone.

4.2 Switches for current I/O unitsThe address range for current I/O units is (32), 33 - 46. Do not useaddress 32, because in this case the current I/O unit operates inCENTRAL UNIT mode and the actual central unit must be set toSUB-UNIT mode. To determine the address of a current I/O unit,add the sum of the weight factors to 32 (for example, programmingswitch values total 7, address of the current I/O unit 32 + 7 = 39).

NOTE: Do not use 32 as the unit address if system have central unit.

Other programming switches have different functions in differentunits, as described below.

5 Adjusting the overcurrentsetting

The principles for changing the current setting in VAM 4C units arethe same as for the central unit. You can see the estimated currentsetting from the led bar on the right side of the unit.

The most accurate way of setting the current limit for the unit is asfollows:

• Turn the potentiometer to the maximum value.

• Feed a test current corresponding to the required setting usinga testing device.

• Lower the setting until the current activation indicator LED of theI/O unit and / or the I>ext indicator LED in VAMP 221 the centralunit are / is lit.

6 BI/BO connection

Each I/O unit also has a BI/O bus. The light I/O units (VAM 10L /VAM 10LD, VAM 12L / VAM 12LD, VAM 3L / VAM 3LX) can transmittrip signal to the central unit or current I/O unit. The current I/O unit(VAM 4C / VAM 4CD) can receive the light information and send thecurrent information either to other I/O units or the multiplying relay.

NOTE: The DI/DO on the VAM units are fast BI/BO signals.

The following DI and DO connections are included in thestandard delivery of VAM 10L and VAM 3L / VAM 3LX:

9.2 I/O unit mounting and wiring

CAUTIONRead this User's Manual carefully before undertaking anyinstallation or wiring work.

Safety instructions

Always observe the national electrical safety regulations whenworking under live conditions. The unit manufacturer is not liable fordamage due to incorrect working methods or failure to observe safetyinstructions.

The correct handling of the unit under all mounting and operatingconditions forms the foundation for its safe use.

CAUTIONAny separately marked notes and warnings must be observed.

The wiring work must be performed according to nationalstandards and any requirements specified by the customer.

Do not connect the auxiliary supply voltage until the installationhas been completed.

Before installation

Before installation, make sure the environmental conditions complywith the requirements specified in Chapter 7.

CAUTIONThe unit contains components liable to damage if exposed to anelectrostatic discharge (ESD). Do not open the unit unless youhave taken appropriate protective measures against ESD.

The manufacturer cannot guarantee operational safety inenvironments that do not satisfy the specified environmentalconditions.

9.2 I/O unit mounting and wiring9 Construction

9.2.1 VAM 10L, VAM 12L, VAM 4C, VAM 3L, VAM 3LXThe units are designed for mounting on a DIN rail. Mount the unitson the rail in such a way that the indicator lights on the front panelare visible and the sensor wiring can be made as easily as possible.

9.2.2 VAM 10LD, VAM 12LD, VAM 4CDThe units are designed for mounting on a door. Hence all indicatorsare clearly visible in normal operation.

9.3 Connecting the VAMP 321 I/O unitsThe I/O units can be connected to the components listed below:

• Enclosure current transformer secondary circuits (VAM 4C andVAM 4CD I/O units only)

• Circuit breaker trip circuits

• External auxiliary supply circuits

• Connections to the VAMP 321 central unit or other I/O units (datacommunication and auxiliary supply)

• Connections to other central units or detection relays (digitalinput (DI) or digital output (DO) bus)

9.4 Connecting the secondary circuits of thecurrent transformers (VAM 4C / VAM4CD only)Connect the secondary circuits of the current transformers to thefollowing screw connectors:

• X1-1, X1-3 (L1)

• X1-5, X1-7 (L2/I0)

• X1-9, X1-11 (L3)

The arc protection system can also be single or two-phase connected.Three-phase connection is nevertheless recommended for optimaloperating speed.

DANGERHAZARD OF ELECTRICAL SHOCK

Do not open the secondary circuit of a live current transformer.

Disconnecting the secondary circuit of a live current transformermay cause dangerous overvoltages.

Failure to follow these instructions will result in death orserious injury.

NOTE: The current measuring channels L1 and L3 must be used inconnection with two-phase current measuring. Single-phase currentor ground fault current must always be connected to the currentmeasuring channel L2/I0; otherwise, an unbalance error will occur.

The specified operating time can only be guaranteed for three-phasecurrent measurement and with the proper voltage supply to all systemcomponents, minimum allowed auxiliary voltage is 21.6 Vdc.

The VAM 4C overcurrent unbalance alarm settings recognizes if thetwo-phase or three-phase monitoring is being used based on theconnections made to the unit and the overcurrent limits set for eachconnection. The two-phase connection monitoring is triggered whenthe L2/I0 connection overcurrent limit differs from the L1/L3 overcurrentlimit settings by 90% or more. This is because in the event two-phasemonitoring is used, the L2/I0 connection is the connection used tomonitor the ground current.

Therefore, the current limit set for the L2/I0 connection should reflectlimits associated with anticipated ground currents. The remainingL1/L3 currents should be balanced, and overcurrent settings for theL1/L3 connection should be reflected as such. The two-phasemonitoring mode is also referred to as “ground-fault mode.”

The three-phase monitoring is triggered when the L2/I0 and L1/L3overcurrent limit settings are similar, reflecting that each phase isunderstood to be in balance with the other two phases.

If detected, the system gives an unbalance alarm after a 10-seconddelay time. The alarm does not affect other operations of the arcdetection system.

The phase discontinuity settings are non-adjustable since all thesetting values have been programmed in the current-monitoring unit.

9.4 Connecting the secondary circuits of the current transformers(VAM 4C / VAM 4CD only)

9 Construction

9.5 Connecting the trip circuits of the circuitbreakersConnect 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 closeat 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 (VAM4 C), select the protection zone controlling the I/O unit using theprogramming switches.

If several trips are required, the multiplying relay VAMP 4R can beused. If VAMP 4R is used, make sure that proper voltage supply isconnected to device.

VIO/en M/A00358

9 Construction9.5 Connecting the trip circuits of the circuit breakers

9.6 Connecting between the central unit andthe I/O unitConnect the central unit to the I/O units with a modular cable of typeVX001. Themodular cable carries all information between the centralunit and I/O units, including data in serial form, arc fault messagesand operating supply to the I/O units.

• Connect the VX001 cable to the arc I/O COM interface of thecentral units.

• 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 toCOM1 or COM2 in the next unit, etc.

All the COM1 and COM2 interfaces are identical, i.e. the cable canalways be connected to either interface. The maximum total lengthof the modular cable, taking into account all the I/O units connectedto the central unit, is 100 m.

NOTE: Use only star connection for I/O units. Maximum single bus cablelength is 30 meters.

CAUTIONHAZARD OF EQUIPMENT DAMAGE

Do not connect modular cables closed loop.

Failure to follow these instructions can result in personalinjury or equipment damage.

59VIO/en M/A003

9.6 Connecting between the central unit and the I/O unit9 Construction

9.7 Connecting separate auxiliary suppliesWhen routing modular cables over long distances (30 meters ofmodular cabling) or when the system contains more than 4 I/O unitsyou should preferably use a separate auxiliary +24Vdc voltage supplywith 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 notrecommended.

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 supplyto all units.

Pay particular attention to the polarity of the wire and cableconnections.

Additional power supply cabling is recommended, min. 1.5 mm2 (AWG16)

Figure 9.5: VAMP 4R block diagram

The multiplying relay VAMP 4R can be used when additional tripoutputs are needed.

VAMP 4R comprises 4 N/O contacts and 4 N/C contacts. They aredivided into two separate groups which can be independentlycontrolled by e.g. the binary output of the I/O units or the central unit.

• Attach the VAMP 4R unit to a DIN rail.

• Connect the auxiliary voltage ( +24V ) to terminal X2-1 (+) andX2-2 (-). Terminals X2-3 and X2-5 are parallel inputs to X2-1(+).Terminals X2-4 and X2-6 are parallel inputs to X2-2(1). Theauxiliary voltage ( +24V ) can be supplied from the central unitor nearest slave ( X2-1 (+), X2-2 (-)).

• Connect the required signal (18-265 V ad/dc) to the trip controlinputs.

• Input “TRIP 1” ( X2-11, X2-12 ) is controlling the trip group 1.Input “TRIP 2” ( X2-8, X2-9 ) is controlling the trip group 2.

• There are 2xN/C + 2xN/O contacts per trip group.

If necessary, input TRIP 1 and 2 can be connected in parallel. Thenall trip relays will operate simultaneously.

9.9 Wiring multiple central unitsA maximum of 16 I/O units and/or central units in ‘slave’ mode canbe connected to one communication bus. In this case, the units canoperate on a maximum of four protection zones (depending on theirprogramming switches). The light and current signals given by theI/O units, including address information, are transferred to eachcentral unit.

If more than one central unit is to be connected to the samecommunication bus, one central unit must be in central unit modeand the other central units in sub-unit mode.

In applications with multiple central units the central units can beinterconnected also via BI/O connections (binary input/output). Inthis case, each part of the system can control four protection zonesper system communication bus. In this case, arc and overcurrentinformation is transferred between the central units without addressinformation.

NOTE: When configurating Vamp 221 arc protection system with multiplecentral units, disconnect I/O-units from central units in slave modeduring their installation procedure.

9.10 Arc sensorsMount the sensors on the switchgear in such a way that they coverthe protection zone as completely as possible. The line of sight mustbe free between the sensor and the supervised area.

If point sensors are used in open compartments (such as bus-barsections), there should be a sensor approximately every 5 meters.Due to the wide detection range of the sensors and the light reflectioninside the switchgear, the mounting position is not critical.

Connecting sensors VA 1 DA and VA 1 EH to the I/O units

The sensors are delivered with 6-metre standard cables or 20-metreshielded cables (to be specified in the order).

After mounting the sensors, connect them to the I/O units as follows:

• Draw the wire to the nearest I/O unit using the shortest routepossible and cut it to a suitable length.

• Connect the arc sensors to the screw terminals X1-1…20. Thepolarity of the arc sensor cables is not critical.

Connecting the ARC-SLx sensors to the I/O units

The sensors are delivered in standard lengths (to be specified in theorder) equipped with terminals compatible with VAM 3L units.

9.9 Wiring multiple central units9 Construction

After mounting the sensors, connect them to the I/O units as follows:

• Draw each end of the sensor to the I/O unit and carefully form aloop of the extra fibre.

NOTE: Do not shorten the extra sensor fibre unless you have appropriateterminal connectors.

• Connect the arc sensors to plug-in terminals X1-R1, T1…R3,T3. While the polarity of the arc sensors is not critical, you mustconnect each end of the fibre to the same channels.

NOTE: Check that the sensor positioning has not changed during shippingand commissioning.

Use a separate VAMPArc Flash Protection Testing Manual for testingtesting each sensor during commissioning.

9.10.1 VA 1 DAYou can be install the arc sensor onto the switchgear wall from theoutside. Press the active part of the sensor through the 10-mm holein the wall and fix it using a 4-mm screw.

You can also surface mount the sensor to the wall using the mountingplates VYX01 or VYX02, available as additional parts.

NOTE: The sensor must not be exposed to direct sunlight or other stronglight. Do not mount the sensor directly under a light source.

9.10.3 ARC-SLxARC-SLx is an fibre sensor that can be mounted on the switchgearto monitor several compartments simultaneously (various bus-barcompartmets, etc.).

The fibre must not touch any live parts of the switchgear or other hotcomponents, since too high temperatures may destroy the fibre.

When mounting the sensor on the switchgear, ensure that thebending radius is long enough (min. 50 mm) and that it is safe fromthe sharp edges of the switchgear.


To avoid false tripping, cover any unused channels of the I/O unit.

Figure 9.10: ARC-SLx

9.10.4 VA 1 DPThe portable pin sensor can be temporarily connected to the I/Ounits. It is used to improve safety when working with live switchgear,for example, Attach the sensor close to the working area, for examplein the breast pocket of the maintenance man.

A pin sensor operates in the same way as a fixed arc sensor. Theonly difference is free mobility within the limits of the connectingcable.
