2 Introduction VAM I/O units

Introduction

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

Purpose

The main purpose of the VAM I/O units is to detect arc light or short circuit current and deliver this information (zone information) to the arc protection central unit and the other VAM I/O units. Additionally

VAM I/O units can be used for tripping appropriate circuit breakers.

Main properties

Arc flash protection system is a modular system consisting of a central unit, I/O units and arc sensors.

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

The I/O unit VAM 10L / VAM 10LD, VAM 12L / VAM 12LD serves as link between the system’s point sensors and the central unit. Each

I/O unit has connections for ten arc sensors, one portable pin sensor and one trip output.

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

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

The arc sensor VA 1 DA is activated by strong light. The sensor transforms the light information into the current signal, which is forwarded through the I/O unit to the central unit. The arc sensor VA

1 EH also operates on the same principle.

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

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

User interface

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

If you unfasten the terminal blocks during installation, remember to tighten the fixing screws after installation! Also tighten the screws even if you did not unfasten the blocks.

VAM 12L

VAM 12L is primary design for selective feeder trip applications. The unit comprises 3 electromechanical trip normally open contacts and one trip alarm change over contact.

The unit has 10 Arc sensor inputs. Tree sensors (of the ten) inputs are dedicated, and are controlling their own trip relay. The unit is ideal for selective trip of cable compartment in case of an ARC fault.

VAM 12L can selectively handle 3 feeders. The rest of the sensors can then supervise the busbar and breaker compartments and will operate in the zone selected by the unit address switches.

4 Programming switches VAM I/O units

Programming switches

Before system implementation, check the positions of the programming switches in accordance with the following basic principles:

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

• Set the programming switches before connecting the supply voltage.

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

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

Switches for arc sensor I/O units

The programming switches of the I/O units are used to determine the unit address and trip relay function.

The system accommodates up to 16 I/O units. Eight addresses are reserved for each protection zone:

• Zone 1 addresses 0…7




The programming switches have different weight factors. To create an address for the I/O unit, turn switches with different values to the

ON position and calculate the sum of their weight factors. The following table shows the weight factors of each programming switch.

Switch 1 determines which light activation activates the arc stage.

When the switch position is ON, the arc stage only activates on the light information provided by the unit's own sensors. In OFF position the arc stage activates on the light information received from any unit in the same protection zone.

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

Switch 3 determines the arc trip criteria. When the switch is in ON position the trip is based on light information only; in OFF position both fault currents exceeding the current limit and light information are required.

VAM I/O units

VAM 12L / VAM 12LD

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

SENSOR 1 activates T1.



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

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

Switches for current I/O units

The address range for current I/O units is (32),33…46. Do not use address 32, because 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 weight factors to 32 (for example, programming switch values total 7, address of the current I/O unit 32 + 7 = 39).

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

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

5 Adjusting the overcurrent setting

Adjusting the overcurrent setting

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

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

• Turn the potentiometer to the maximum value.

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

• Lower the setting until the current activation indicator led of the

I/O unit and the I>ext indicator led in the central unit are lit.

Each I/O unit also has a BI/O bus. The light I/O units (VAM 3L / VAM

3LX, VAM 10L / VAM 10LD, VAM 12L / VAM 12LD) can transmit trip 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 the current information either to other I/O units or the multiplying relay.

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

I/O unit mounting and wiring

Read this User's Manual carefully before undertaking any installation or wiring work.

Safety instructions

Always observe the national electrical safety regulations when working under live conditions. The unit manufacturer is not liable for damage due to incorrect working methods or failure to observe safety instructions.

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

Any separately marked notes and warnings must be observed.

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

Do not connect the auxiliary supply voltage until the installation has been completed.

Before installation

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

The unit contains components liable to damage if exposed to an electrostatic discharge (ESD).

Do not open the unit unless you have taken appropriate protective measures against ESD.

The manufacturer cannot guarantee operational safety in environments that do not satisfy the specified environmental conditions.

VAM 3L, VAMP 3LX, VAM 10L, VAM 12L, VAM

4C

The units are designed for mounting on a DIN rail. Mount the units on the rail in such a way that the indicator lights on the front panel are visible and the sensor wiring can be made as easily as possible.

VAM 10LD, VAM 12LD, VAM 4CD

The units are designed for mounting on a door. Hence all indicators are clearly visible in normal operation.

Wiring of the I/O units

The I/O units can be connected to the following:

• secondary circuits of the current transformers of the switchgear

(VAM 4C only)

• the trip circuits of the circuit breakers

• external auxiliary supply circuits

• connections to the central unit or other I/O units (data communication and auxiliary supply)

• connections to other central units or protection relays (DI or DO bus)

Wiring the secondary circuits of the current transformers (VAM 4C / VAM

4CD only)

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 protection 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 earth-fault current must always be connected to the current measuring channel L2/I0; otherwise, an unbalance error will occur.

The specified operating time of 7ms can only be guaranteed for three-phase current measurement.

Wiring the trip circuits of the circuit breakers

Connect the circuit breaker’s trip circuit to the following terminals:

TRIP1: X2-15, X2-16 (fast)

In the event of an arc fault, the output contact will close at 7 ms when three-phase current measurement is used.

9 Construction 9.6 Wiring between the central unit and the I/O unit

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 protection zone controlling the I/O unit using the programming switches.

If several trips are required, the multiplying relay VAMP 4R can be used.

Wiring between the central unit and the

I/O unit

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.

• Connect the VX001 cable to the arc I/O COM interface of the central 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 to

COM1 or COM2 in the next unit, etc.

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 100 m.

Use only star connection for I/O units. Closed loop will cause communication errors.

Wiring separate auxiliary supplies

When routing modular cables over long distances or when the system contains several I/O units, you should preferably use a separate auxiliary supply parallel with the modular cable.

Connect the auxiliary supply to the 24 V terminals of the central unit to the 24 V terminals in the I/O units. Alternatively, you can also use a separate external voltage supply 3P004.

Pay particular attention to the polarity of the cable connections.

VAMP4R Block diagram

Figure 9.1: VAMP 4R block diagram

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

VAMP 4R comprises 4 N/O contacts and 4 N/C contacts. They are divided into two separate groups which can be independently controlled 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 (+) and

X2-2 (-). 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). The auxiliary voltage ( +24V ) can be supplied from the central unit or nearest slave ( X2-1 (+), X2-2 (-)).

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

• 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. Then all trip relays will operate simultaneously.

9 Construction 9.9 Wiring multiple central units

Wiring multiple central units

A maximum of three central units can be connected to one communication bus. In this case, the units can operate on a maximum of four protection zones (depending on their programming switches).

The light and current signals given by the I/O units, including address information, are transferred to each central unit.

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

In applications with multiple central units the central units can be interconnected also via BI/O connections (binary input/output). In this case, each part of the system can control four protection zones per system communication bus. In this case, arc and overcurrent information is transferred between the central units without address information.

When configurating arc protection system with multiple central units, disconnect I/O-units from central units in slave mode during their installation procedure.

9.10 Arc sensors

9.10


Arc sensors

Mount the sensors on the switchgear in such a way that they cover the protection zone as completely as possible. The line of sight must be free between the sensor and the supervised area.

If point sensors are used in open compartments (such as bus-bar sections), there should be a 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 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-metre shielded 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 route possible and cut it to a suitable length.

• Connect the arc sensors to the screw terminals X1-1…20. The polarity 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 the order) equipped with terminals compatible with VAM 3L units.

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 a loop of the extra fibre.

Do not shorten the extra sensor fibre unless you have appropriate terminal 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 must connect each end of the fibre to the same channels.

ARC-SLx is an fibre sensor that can be mounted on the switchgear to monitor several compartments simultaneously (various bus-bar compartmets, etc.).

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

VIOen M/A001

VAM I/O units 9 Construction 9.10 Arc sensors

When mounting the sensor on the switchgear, ensure that the bending radius is long enough (min. 80 mm) and that it is safe from the sharp edges of the switchgear.


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

Figure 9.6: ARC-SLx

VA 1 DP

The portable pin sensor can be temporarily connected to the I/O units. It is used to improve safety when working with live switchgear, for example, Attach the sensor close to the working area, for example in the breast pocket of the maintenance man.

A pin sensor operates in the same way as a fixed arc sensor. The only difference is free mobility within the limits of the connecting cable.
