FOR YOUR SAFETYFollow the instructions

Follow the instructions for installation, operation and maintenance.

Use in areas subject to explosion hazards

The relay module and relay display card are not designed for use in a flammable atmospherewithout suitable protection.

Liability for proper function or damage

Liability for proper function of this apparatus is irrevocably transferred to the owner oroperator to the extent that the apparatus has been commissioned, serviced or repaired bypersonnel not employed or authorised by Draeger Service, or when this apparatus was usedin a manner not conforming to its intended use.

Draeger Limited can not be held responsible for any damage caused by non-compliance withthe above recommendations. The warranty and liability provisions of the terms and conditionsof sale and delivery of Draeger Limited are likewise not modified by recommendations givenabove.

Maintenance

This apparatus must be inspected and serviced by experts at regular intervals and a recordmaintained of such inspections and servicing. Repairs and general overhaul of this apparatusshould only be carried out by competent personnel.

We recommend that either a training course or service contract is obtained from the DraegerService department and that all repairs are also carried out by them.

Safe operationFor safe operation:

• Set relays on relay modules normally energised. In the event of power loss,communications failure or configuration data loss, the relays will de-energise.

• Connect an alarm device or other indicator to the operational fault relay on the relaydisplay card.


OPERATIONIntended use

The REGARD relay modules and relay display card provide:

• Additional common and voted alarm relays for a system comprising any combination ofchannel cards.

• A1, A2, A3 and Fault alarm relays for each channel of a Regard HART card or 8-channeldisplay card.

• Additional alarm relays for single-channel Regard cards.

The relay modules and relay display card are intended for permanent installation in a non-hazardous environment, such as a control room or marshalling cabinet.

DescriptionThe relay display card fits into the Regard rack and controls up to 16 relay modules. Eachrelay module has 16 relays. The relay modules are connected to the relay display card by asingle twisted-pair cable. Relay modules can be located up to 1km from the relay displaycard, allowing shorter cable runs between the actuating relays and the controlled devices.

Up to eight relay display cards can be fitted in a Regard system – i.e. connected to the sameRS-485 bus. This restriction is removed if remote configuration of the relay display cards isnot required.

The relay display card “listens” to the messages on the RS-485 bus between the Regardmaster card and channel cards. The relay display card requires a Regard master card foroperation. The master card must be configured to communicate with all channel cardsthat are programmed on the relay display card .

Operational fault relayThe relay display card has one relay, that indicates a critical operational fault of the relaydisplay card or relay module(s). This relay is always normally energised, latching and non-acknowledgeable.

Electromagnetic compatibilityThe Regard relay module and relay display card have been tested for compliance with theEMC Directive. Take the following steps to ensure compliance:

• Fully follow the installation instructions• Observe instructions to use screened cable, where given

Instructions or precautions which are essential for electromagnetic compatibility are identifiedby “EMC!” in the margin.


Display card front panel controls and indicatorsDisplay

Display normally shows the state of each alarm relay in sequence. When a relay is in itsalarm state, only relays in alarm are displayed.

Operational faultsAn operation fault is a failure in the operation of either the relay display card or the relaymodule. Operational faults are either:• critical – card may stop working, or• advisory – card will continue to work safely, but its functions may be limited

When an operational fault occurs:• Power LED flashes once a second• If fault is critical, operational fault relay de-energises• Display shows fault code alternately with normal display

Press Reset to clear the fault. If fault will not clear, or recurs, call Draeger Service.

Loss of communication between relay display card and relay module(s)If the RS-485 connection between the relay display card and a relay module is broken,or the communications between the two is otherwise interrupted, all relays on the relaymodule will de-energise.

• There is a delay of 5 seconds, after the connection is broken, before the relays de-energise. If the connection is re-made within 5 seconds, the relays do not de-energise.

• When the connection is re-made, the relays will stay de-energised for 10 seconds.


INSTALLATIONHandle circuit boards with care during installation. Do not touch the circuit boards orcomponents.

Use of the relay modules and relay display card requires a Regard master card. All Regardchannel cards (e.g. 4-20, Ex, HART, 8-channel) must be connected to the same RS-485 busas the relay display card and the master card.

The diagram below shows how the relay display card and relay modules connect to a Regardsystem. Note that there is a separate RS-485 bus from the relay display card to the relaymodules. (Diagram for illustration only.)

RELAY MODULE

Set module numbersSet the ID number of each module using the rotary switch (SW1) on the module.

SW1

Each module connected to a relay display card must have a unique ID number.• First module must be 0• ID numbers must be contiguous– do not leave any gaps in the sequence.

Examples:• 3 relay modules, numbers 0, 1, 2.• 16 relay modules: numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F.

• Relay modules are identified by the relay display card as “ID number + 1”, e.g. the modulewith ID number 0 will be module 1 on the relay display card.

• The order of the relay modules on the RS-485 bus does not affect the operation of therelay modules. Using a logical numbering sequence for the modules makes programmingthe relay display card easier.


Connect equipment to relay terminalsNormally-open and normally-closed contacts are labelled on the relay module. Labels showfunction of relay when de-energised:

C

EMC! Use screened cable for connections to relays

Connect DC supply to modulesConnect 24V DC supply to terminals marked 24V and 0V. Observe the polarity of theterminals. Second pair of terminals can be used to connect supply to another relay module.

• Do not connect more than 4 modules in series.• Do not switch on 24V supply to relay modules until installation is complete.

Switch-on and initial checksSwitch on DC supply to the relay display card and the relay module(s).

Check that the Power LED on the relay display card and relay modules are lit.

If power to the relay modules is connected more than 5 seconds before the relay display card,the relay display card will indicate a communications fault warning. Press R push button tocancel the warning.

Relay display card may indicate a fault condition until it is correctly configured.


CONFIGURATIONCommand mode

Configuration and maintenance of the display card is performed using front panel controls anddisplay, by setting the card into command mode.

In command mode:

• Display of relays status is replaced by display of command mode options and configurationsettings;

• Operation of all relays on relay modules is prevented (“inhibited”). Inhibit LED on frontpanel of card is lit.

Configuration and maintenance commands are operated by selecting the command numberusing the and push buttons.

Entering command mode automatically inhibits all alarm relays on the module(s) connectedto the relay display card.
