Appendix C: Alarms and Relays
Alarm Relays
The control unit is provided with six alarm relays; four to provide the actual alarm condition,
and two to provide the severity associated with the alarm. The severity relays transmit the
either PMJ or PMN. Each alarm is factory assigned a severity based on industry practices,
however, they may be reassigned to MAJ, MIN, or RO (Record Only). An alarm condition
with the RO severity results in the system controller transmitting the alarm without the
severity. That is, neither MAJ (PMJ) nor MIN (PMN) is transmitted with the alarm.
The four selectable alarm relays are called Alarm Relay 1 (ALM1) through Alarm Relay 4
(ALM4). Relays are user definable in that the user may assign any combination of alarms
from a given set of alarms. The following table shows which alarms may be assigned along
with their factory default settings.
Alarms
Table C-1 shows a list of all alarms along with their descriptions, default settings, ranges
and/or severity, and affected alarm relays and LEDs.
