PS Series Inverter/Charger
Part No. 3597
Rev. D: November 23, 1999
PS Series Troubleshooting using the LED Indicators Page 2 of 2
INVERTER MODE - If ERROR LED comes on, see ERROR CAUSES section (continued)
No AC power output
INVERT LED (yellow) is on
with no ERROR LED.
Check for AC voltage on inverter’s AC terminal block (Between Hot AC output and
Neutral AC output).
1) If there is no AC voltage on the AC
terminal block:
Check for open circuit breaker on PS
inverter. If circuit breaker on PS inverter
is not open (popped)
– have inverter serviced.
2) If there is AC voltage on the AC
terminal block :
Check for open AC output breakers or
fuses and bad output wire connections
Low AC power output or Low surge
power and INVERT LED is on
(AC inductive loads are not running at
full speed).
Insufficient DC current being provided
to the inverter to operate the AC loads
Check the battery voltage, fuses or
breakers and cable connections.
Ensure the battery bank is sufficient
(check for low DC voltage while running
the load).
Ensure the cable length and size is
correct (see owner's manual for correct
cable). Tie the battery cables together to
reduce inductance.
BATTERY CHARGER MODE - If ERROR LED comes on, see ERROR CAUSES section.
AC IN LED is on, but will not start
charging.
(allow 40 seconds to synchronize)
Check for the correct AC voltage or
frequency at the AC input terminal.
AC frequency at the AC input terminal is
out-of- tolerance (too high or low) or AC
voltage outside ‘Upper/Lower VAC limit’
settings
If AC source is a generator, adjust AC
voltage o][r frequency accordingly.
Charger drops off before full
charging has finished.
Check for the correct AC voltage or
frequency at the AC input terminal.
AC voltage or frequency at the
AC input terminal drops out-of-tolerance
(too high or low).
If AC source is generator adjust
accordingly. Switch ‘MAX AC Amps In’
to lower AC input level.
Circuit breaker on PS inverter is open Engage circuit breaker on side of unit
(press hard on breaker button to ensure
it is engaged)
Ambient temperature may be high
causing unit to overheat and ramp down
the charging.
Cool the unit down or check the inverter
cooling fan, or check for anything
preventing air flow
Charger drops off before full
charging (or equalization) has
finished
ERROR LED comes on and AC output
drops momentarily.
Cold temperature around batteries with
BTS (Battery Temperature Sensor)
installed may be causing unit to reach
HIGH BATTERY CUTOUT setting
Disconnect BTS during charging.
Charger output is low Loose or corroded battery connections Check and clean all connections
Loose AC input connections Check all AC wiring connections
Weak/soft batteries Replace batteries
Battery cables too small or too long Refer to cable and battery
recommendations in owner’s manual
Batteries being charged above the
Bulk/Float setting
NOTE: To bring batteries that are cold to the correct state of charge may require
charging at a higher voltage. Remove the BTS and determine if your voltage returns
to the bulk/float voltage
Temperature probe is installed Ensure that the temperature probe is not in a cold area or has not fallen off the
batteries.
Ensure that there is no other DC charging source on the batteries
Temperature probe is not installed Ensure that there is no other DC charging source on the batteries
