IS200WETBH1ABA General electric (ge) module

To prevent excessive current flow along the rack backplane in installations where more than eight 5704 Catalytic Cards are used, it is recommended that the Control Cards are powered via their associated Quad Relay Interface Card and the DC Input Card used to power the Engineering Card only. If required, a stand-by backup battery supply may also be connected to the auxiliary dc input connections. The PSU and AUX connections are isolated from each other by diodes. The DC Input Card also provides RFI filtering and reverse polarity protection. In addition, the DC Input Card provides an interface to the Engineering Card plug-in modules via TB2. The functions of the six terminals will vary dependent upon the module fitted. For full details refer to: a. 05701-M-5006System 57 Control System Modbus Interface Option RS485/422 b. 05701-M-5007 System 57 Control System Event Printing Option RS232

For 5704 systems with more than eight catalytic control cards, it is recommended that the dc power is connected direct to each channels' Quad Relay Card.

Power Supply Unit Upgrades

 Both power supply units are provided with internal connections to enable a power upgrade to 100W by the addition of a second 50W Switched Mode AC to DC Power Supply Module (Part Number 05701- A-0440). A second sub-unit (Part Number 05701-A-0441) can be fitted to the basic 16-way power supply unit if more than 100W is required to operate the system. The additional sub-unit will contain a 50W Switched Mode AC to DC Power Supply Module as standard and will therefore give an additional 50W of available power. If required a further 50W Switched Mode AC to DC Power Supply Module (Part Number 05701- A-0440) can be added to this second sub-unit to bring the power availability up to 200W. The switched mode power supply modules used are fully overload protected and are designed to be connected together. 8.3 Power Supply Connections The input ac power supply is connected via a three core cable at the rear of each unit. The nominal 24V dc output supply is connected via a twin core cable at the rear of each unit.

CONTROLS AND FACILITIES

The 5704 Series Control System is equipped to provide the operational and engineering facilities necessary to fully maintain a system of gas detection equipment. Each control card within a rack system displays a sensor reading, alarm status condition and channel reading number. Further information can be gathered and, depending on the security status, certain settings can be adjusted by means of an Engineering Card fitted to the rack. The relay outputs of the system are configured to provide a range of output alarm functions as follows: a. Fault Alarm The fault alarm activates when a fault is detected in the control channel or associated sensor and is not user configurable. In addition the FAULT LED will be illuminated as described in Section 2.3.1a. b. Inhibit Alarm The inhibit alarm activates when the system alarms are inhibited for any reason and is not user configurable. In addition the INHIBIT LED will be illuminated as described in Section 2.3.1b. c. A1, A2 and A3 Level Alarms The A1, A2 and A3 level alarms are activated when the level of gas being measured crosses the preconfigured alarm threshold. In addition the relevant LED will be illuminated as described in Section 2.3.1c, d and e.
