Description (if = 1)
Speed 0/1 is less than previous measured. Reported speed is estimated until a further pulse is detected,
or until zero speed is determined (maximum pulse wait time exceeded).
Tacho sensor fault. Indicates bias out of range and/or speed out of range and/or TSCX module fault.
Alarm Status Structure
The alarm status structure consists of an array of 13 records
present the status of associated voted alarms.
If Alarm Status Alignment is Dynamic, then status records are also assigned to
relays that are configured to act only on fault, and to any unused (not enabled)
relays.
See
Alarm System Overview on page 211
page 212
for further information on how Alarm Statuses are associated with
Voted Alarms and Relays.
Module status excludes an assembly for each measurement alarm. The status of
a measurement alarm that is referenced by a voted alarm is included in the
alarm status record that is associated with the voted alarm.
