Fault Alarm Masked (◄ ►E)
Use the ◄ ► arrow keys to select Fault, Alarm, or Masked, and then press ENTER. Note the
following:
Selection State
Fault Both SUM FAULT LEDs are lit and the Summary Fault Relay is tripped to the Fault
position.
Alarm Both SUM FAULT LEDs are lit, but the Summary Fault Relay position is not affected
Masked Neither the SUM FAULT LEDs nor the Summary Fault Relay are affected.
If all power supplies in the chassis are out of range, then both SUM FAULT LEDs are lit (if
able) and the Summary Fault Relay is tripped to the Fault position.
Power Supply 2 is typically available when the optional Dual Entry Module AC
Power is installed on the optional redundant chassis. Most standalone (i.e.,
single-thread or non-redundant) chassis will not have this AC power option.
For any chassis containing a single power supply, you must set Power Supply
2 as “Masked” to prevent the occurrence of misleading alarms.
