Controller
7 The inactive unit could not establish two-way communication with the central
control and has switched activity back to the originally active unit. You must
clear all faults on the inactive unit before attempting to clear the alarm
condition on the active unit.
Go to step 9.
8 The SWACT controller does not recommend a SWACT for one of the
following reasons:
• IMC link failures
• message link failures
• parity audit failures
• superframe sync failures
• inactive unit was unable to keep activity last time
• dropping activity
• pre-SWACT query failure
• unit is jammed inactive
• unit is in overload
• pre-SWACT difficulties
