The RMP contains a local horn and the following backlit status indicators:
SYSTEM NORMAL
The UPS is energized (either with utility power
or battery backup) and is supplying
conditioned power to the critical load.
NO REDUNDANCY
This indicator applies only to parallel systems
when one cabinet is not functioning. This
feature is not available on this system.
ON GENERATOR
This alarm means that the UPS input and
bypass are being supplied by the power from
the generator, instead of from the utility power.
ON BYPASS
The bypass source is supplying the critical
load. Usually this means that the UPS is not
energized. The load is not protected in Bypass
mode, and a horn sounds after 30 seconds.
UPS ALARM
The UPS system is issuing an alarm.
Conditions that affect the current UPS mode
are indicated by the alarm lamps and horn on
the UPS.
ON BATTERY
The UPS battery backup is supplying the
critical load. The utility power is either
interrupted or out of specification. The
SYSTEM NORMAL indicator is also lit.
BYPASS UNAVAILABLE
The UPS system is in Normal mode, but
a bypass source is not within specification.
A horn sounds after 30 seconds.
SHUTDOWN IMMINENT
The UPS is preparing to shut down because
the UPS is in Battery mode and the DC voltage
is approaching its low limit.
This light is accompanied by an audible alarm
horn.
