Possible Problem(s) Possible Solution(s)
PMN
AMBER
MIN, AC Fail None GREEN
Single Rectifier not
receiving ac power.
• AC input circuit breaker
has opened.
•
AC input voltage is out
of range
.
1. Verify ac power to rectifier is
available.
2. Verify rectifier input circuit
breaker is closed.
3. If problem not corrected,
replace rectifier.
PMJ
RED
MIN, AC Fail
MAJ, Multiple
AC Fail
MAJ, Battery on
Discharge
None GREEN
Multiple rectifiers not
receiving ac power,
batteries are powering
load.
• AC input circuit breakers
have opened.
•
AC input voltage is out
of range.
•
Internal rectifier fault.
4. Verify ac power to rectifiers is
available.
5. Verify rectifier input circuit
breakers are closed.
6. If problem not corrected,
replace rectifier.
PMJ or
PMN
AMBER or
RED
MIN, AC Fail
MAJ, Multiple
AC Fail
None GREEN
A rectifier, multiple
rectifiers, or the entire
system has lost AC and
one or more rectifiers
have been removed from
the system while under
this condition.
1. Verify that ac power to all
rectifiers is available.
2. Verify that rectifiers all
report good AC
3. Issue the uninstall equipment
under the operations menu
for any rectifier that may
have been removed during
the AC fail.
PMJ
RED
MAJ, Battery on
Discharge
AC OK
DC OK
GREEN
Rectifier output voltage
has fallen below the
battery on discharge
threshold set by the user.
1. If commercial ac power is
present but the system voltage
remains low, call your local
field representative.
2. Investigate other alarms that
may be present such as
rectifier related problems.

AMBER
MIN, Rectifier
Fail (Note 1)
AC OK
ALARM
(Note 1)
GREEN
Rectifier output has
dropped below 36V,
rectifier has entered
hiccup mode.
Replace rectifier.
PMJ
RED
MAJ, Rectifier
Fail
AC OK
ALARM
(Note 1)
GREEN
All rectifier outputs have
dropped below 36V, all
rectifiers have entered
hiccup mode.
Defective controller.
Remove controller; if output
voltage does not go to set-point
previously set by user, call your
local field representative.

Pulsar Displays – Alarm Severity indicated by back-light color of the display: Red = Critical or Major, Amber = Minor,
Green = Normal.
Phoenix Displays – Alarm Severity indicated by separate LEDs: PCR (Red) = Critical, PMJ (Red) = Major, PMN (Amber)
= Minor, SYSOK (Green) = Normal
