For example, if the total cumulative time that an error has been present
reaches the aggregate time (2.5 sec default) in less than the time set in OOS,
the card is put into an out-of-service state. If it took more than the preset time
for the error condition to register, the card could be put into NNDC, NNC or
MAINT states. The card remains in the alarm condition until the error has
improved and after the Group 2 guard timers expire.
Define Group 2 Error Thresholds
You are able to define Group 2 error thresholds in LD 73. Only the highest
priority Group 2 alarm condition is active at a time. The order of priority
(from highest to lowest) is: LOS, AIS, LFAS, LMAS, RAI.
