Alarm Relay Trigger Enable
Figure 10: Alarm Relay Trigger Enable
Alarm Relay Trigger, accessible via the AES/LTC & RELAY connector on the rear panel can be set
for PSU1, PSU2, and the Fan; they are individually enabled by setting Switches of SW1 on the 1945
Fan Module (fitted to the 3U Frame door) to the ‘ON’ position. The relay operation is the sum of all
the enabled switches.
Switch 1-1 is the enable for PSU1 position
Switch 1-2 is the enable for PSU2 position.
Switch 1-3 enable for the fan alarm
See section 5.1.5 for details of the 9-Way Pin out for connection to the Relay signals.
NOTE:
Settings should match your frame configuration, for example, if you only have one PSU fitted
in the PSU2 position then you should set switch 1-1 to ‘OFF’ to disable the empty PSU1 slot
generating a false alarm trigger.
