Galaxy Pulsar Edge Power System Controller
Issue 3 October 2011 195
Appendix E: Alarms and Relays
Alarm Relays
The Galaxy Pulsar Edge can be configured to provide up to six alarm relays depending on the
controller configuration. Four alarm relays provide the alarm condition and two provide the
overall system severity associated with the alarm. Presently, the maximum number of relays
available in the Infinity NE841A and QS841E is six. The maximum number of relays in the
CP841A and SPS841A controllers is five. The severity relays transmit Power Major (PMJ) or
Power Minor (PMN). Each alarm is factory assigned a severity based on industry practices,
however, they may be reassigned to MAJ, MIN, Warning, or RO (Record Only). An alarm
condition with the RO severity results in the system controller not transmitting the alarm but is
stored in the history log. PCR, PMJ nor PMN severities are transmitted along with the alarm.
The four selectable alarm relays are called User Alarm Relay 1 (R1) through User Alarm Relay 4
(R4). 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 E-1 shows a list of all alarms along with their descriptions, default settings, ranges and/or
severity, and affected alarm relays and LEDs. Controllers with less relays than six will lose user
relays starting with R4, then R3, etc.
