Alarm Relay Map Configure the relay outputs, using the Alarm Relay Map. Each
Alarm Map corresponds to a relay output. For example, Alarm
Map 01of04 corresponds to the first of four relay outputs. The
second line, in brackets [ ], lists the items that you have selected
to map to the selected relay/ The third line allows you to select
the alarms to which you want to map the relay:
• Any Load (L)—Maps to over- or under-current alarms for
circuit breaker panels and branch circuits.
• Overload (O)—Maps to over-current alarms for circuit
breaker panels, branch circuits, and SYSGND.
• Input Voltage (Vi)—Maps to any input voltage alarm.
• Output Voltage (Vo)—Maps to any output voltage alarm.
• PDU in Bypass (By)—Mapping this option will cause the
relay outputs to actuate when the Q3 circuit breaker is
closed.
• Any Breaker (Br)—Mapping to this option will cause the
relay outputs to actuate when the input, bypass input (Q10),
or cross-tie output breaker is not in the normal state.
• Contacts 1–4 (C1, C2, C3, C4)— Maps to the input contact
alarms.
Before exiting the screen, to save your changes, select the Apply
Now option on the bottom line of the screen.
