CHARGER FAULT CODE SYMPTOMS
Symptom Possible
Cause
Recommended Action
15) Lo DC
fault code or
output voltage
low. DC breaker
OFF or no DC
voltage at the
charger. Check to see if the CB2 DC breaker is OFF or tripped open. If OFF, go to
that symptom (#11 or #12). If DC breaker is ON, verify that the Green "DC
ON" LED is on? If not, go to the "DC ON" LED off symptom (#21).
Battery is
discharged.
After an AC power failure, battery discharge, or for any other reason, it may
take a few hours for the charger to charge the batteries above the DC Lo set
point value (SECTION 11.3.4).
Wrong Display
voltage.
If the breaker and LED are both on, then measure the DC voltage at the
charger. It should be close to what is displayed on the control board display.
If not, the charger has an internal component failure. See wrong display
voltage symptom (#5).
The value in
the DC Lo set
point is too
high.
If the display voltage is correct, calculate the volts per cell value, then verify
that the Float voltage setting (SECTION 11.3.3) is higher than the DC Lo set
point (SECTION 11.3.4). If the charger was in Equalize Mode, verify that the
Equalize voltage setting (SECTION 11.3.3) is higher than the DC Lo set point.
If the charger is setup to do Temperature Compensation (SECTION 11.3.3),
verify that the calculated voltage after temperature compensation is higher
than the DC Lo set point. Hot temperatures will decrease the battery charger
voltage if using Temperature compensation. Adjust DC Lo set point in the
alarm setting's menu accordingly.
Bad A1 SCR
driver board.
If voltages are correct, calculate the volts per cell value. If the value
calculated is higher than the DC Lo value in the Alarm Setting's menu, then
power the charger down completely and then power it back up. If the fault
code returns, replace the A1 SCR Drive Board.
Charger type
and battery
type not
matched.
If value is lower, then verify that the battery type and voltage is proper for the
charger type on the charger label. Verify charger type in DC setting's menu
(SECTION 11.3.3) is proper. See wrong charger type symptom (#7), if
control board shows wrong charger type.
No charger
output current
or current too
low.
If the voltage is rising, the fault should clear after the voltage gets above the
set point. If the voltage is dropping, then the charger is either not providing
enough DC output current or none at all. Check the DC amps setting in the
DC setting's menu (SECTION 11.3.3) and raise the value, if necessary. If the
display shows no DC current, then go to the “No charger DC current”
symptom (#8).
16) EOD fault
code. See the Lo DC symptom (#15), because it is similar. Check EOD set point
values (SECTION 11.3.4) instead of DC Lo set point values.
17) LoLoc
fault code. Bad battery or
bad
connections. Check battery voltage and connections. Switch the CB1 AC breaker OFF,
then ON. The Charger should start charging the battery and bring the voltage
up. See Lo DC symptom (#15) if charger does not begin to charge. This fault
occurs about 3 minutes after the charger shows the DC output voltage drop
below about 0.2 volts per cell or a near short. This fault will lockout or not
allow the charger to charge the batteries until the AC input voltage is cycled
off then back on or the battery voltage of the charger shows increases above
this value.
