4 REGARD Relay Module & Relay Display Card FOR YOUR SAFETY Follow 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 atmosphere without suitable protection. Liability for proper function or damage Maintenance Liability for proper function of this apparatus is irrevocably transferred to the owner or operator to the extent that the apparatus has been commissioned, serviced or repaired by personnel not employed or authorised by Draeger Service, or when this apparatus was used in a manner not conforming to its intended use. Draeger Limited can not be held responsible for any damage caused by non-compliance with the above recommendations. The warranty and liability provisions of the terms and conditions of sale and delivery of Draeger Limited are likewise not modified by recommendations given above. This apparatus must be inspected and serviced by experts at regular intervals and a record maintained of such inspections and servicing. Repairs and general overhaul of this apparatus should only be carried out by competent personnel. We recommend that either a training course or service contract is obtained from the Draeger Service department and that all repairs are also carried out by them. Safe operation For 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 relay display card.

REGARD Relay Module & Relay Display Card 5 OPERATION Intended use The REGARD relay modules and relay display card provide: Additional common and voted alarm relays for a system comprising any combination of channel cards. A1, A2, A3 and Fault alarm relays for each channel of a Regard HART card or 8-channel display card. Additional alarm relays for single-channel Regard cards. The relay modules and relay display card are intended for permanent installation in a nonhazardous environment, such as a control room or marshalling cabinet. Description The relay display card fits into the Regard rack and controls up to 16 relay modules. Each relay module has 16 relays. The relay modules are connected to the relay display card by a single twisted-pair cable. Relay modules can be located up to 1km from the relay display card, 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 same RS-485 bus. This restriction is removed if remote configuration of the relay display cards is not required. The relay display card listens to the messages on the RS-485 bus between the Regard master card and channel cards. The relay display card requires a Regard master card for operation. The master card must be configured to communicate with all channel cards that are programmed on the relay display card. Operational fault relay The relay display card has one relay, that indicates a critical operational fault of the relay display card or relay module(s). This relay is always normally energised, latching and nonacknowledgeable. Electromagnetic compatibility The Regard relay module and relay display card have been tested for compliance with the EMC 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 identified by EMC! in the margin.

Tripped LED off Operational faults An operation fault is a failure in the operation of either the relay display card or the relay module. 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 relay module will de-energise. There is a delay of 5 seconds, after the connection is broken, before the relays deenergise. 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.

10 REGARD Relay Module & Relay Display Card INSTALLATION Handle circuit boards with care during installation. Do not touch the circuit boards or components. Use of the relay modules and relay display card requires a Regard master card. All Regard channel cards (e.g. 4-20, Ex, HART, 8-channel) must be connected to the same RS-485 bus as the relay display card and the master card. The diagram below shows how the relay display card and relay modules connect to a Regard system. Note that there is a separate RS-485 bus from the relay display card to the relay modules. (Diagram for illustration only.) MASTER CARD CHANNEL 1 CHANNEL 2 CHANNEL 99 MAIN RS-485 BUS RELAY DISPLAY CARD RS-485 BUS TO S Install relay display card Fit the relay display card in slot in Regard rack. EMC! Tighten the screws on the front panel fully. Install relay modules EMC! Install the relay module in a metal enclosure or other enclosure which gives protection against radio-frequency interference. Fit relay modules to 35mm symmetric or 32mm asymmetric DIN rail. Maximum cable length of the RS-485 bus must not exceed 1000m Voltage difference between 0V at the relay display card and all relay module must not exceed 5V. Use an RS-485 isolator if the voltage difference is greater that 5V.

REGARD Relay Module & Relay Display Card 13 Disallowed connection arrangements Star NOT ALLOWED RELAY DISPLAY CARD Tree NOT ALLOWED RELAY DISPLAY CARD Set module numbers Set 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 module with 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 the relay modules. Using a logical numbering sequence for the modules makes programming the relay display card easier.

14 REGARD Relay Module & Relay Display Card Connect equipment to relay terminals Normally-open and normally-closed contacts are labelled on the relay module. Labels show function of relay when de-energised: NC C NO EMC! Use screened cable for connections to relays Connect DC supply to modules Connect 24V DC supply to terminals marked 24V and 0V. Observe the polarity of the terminals. 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. 24V 0V

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 to cancel the warning. Relay display card may indicate a fault condition until it is correctly configured.
