GCD207B101 3BHE024642R0101 process control card

Message Display The message display consists of a four character, 14 segment display which provides intelligent reporting of the sensor status or information on a selected engineering function. For control cards fitted with the high integrity relay outputs performing master, zone or voted alarms, the alarm state will also be indicated as follows: BEAM - Beam Blocked Alarm MSTR - Master Alarm ZONE - Zoned Alarm VOTE - Voted Alarm

The icon provides a simple indication that the display is functioning and changes when the channel card is selected for operation with the Engineering Card.

Five LEDs on the front panel of the control card

 indicate the operational status of the channel as follows: a. FAULT - Amber LED The fault LED provides an indication in the event of a sensor hardware failure, if the sensor signal is outside pre-defined limits or if the channel card has detected a hardware or software fault. b. INHIBIT - Amber LED The inhibit LED indicates when the channel is in the inhibit condition. This condition can be selected manually and remotely, or occurs automatically: during start-up for a pre-defined period of approximately 30 seconds, when carrying out certain engineering functions such as zero, span, 1st span and alarm test. Depending upon the configuration, the control card may enter the inhibit mode for a short period of time immediately after a fault condition is cleared

During the inhibit condition

 the channel card will continue to read the gas sensor reading, however, no action is taken in the event of an alarm condition being exceeded. c. A1 - Red LED The A1 LED indicates that the preset first level gas alarm has been exceeded. This alarm will not function in the event of either a fault or inhibit condition being active. d. A2 - Red LED The A2 LED indicates that the preset second level gas alarm has been exceeded. This alarm will not function in the event of either a fault or inhibit condition being active. e. A3 - Red LED The A3 LED indicates that the preset third level gas alarm has been exceeded. This alarm will not function in the event of either a fault or inhibit condition being active.
