Possible Problem(s) Possible Solution(s)
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.
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.
1. Verify ac power to rectifiers is
available.
2. Verify rectifier input circuit
breakers are closed.
3. If problem not corrected,
replace rectifier.
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.
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.
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.
