Great Planes PolyCharge4 - GPMM3015 User Manual

If for any reason it is desired to stop the charge process (if the
pack is too warm, incorrect cell detection or charger becoming
excessively hot, etc.), re-press the START/STOP button. The
charger will sound a single beep, and the charge process will
stop (LED will turn off).

For each output, all error alarms are indicated by flashing the
orange LED accompanied by an audio tone. PolyCharge4 can
identify 6 different possible errors during charge. Each error type
is identified by a certain number of flashes of the orange LED
and audible tones. The list of recognizable errors is as follows:

If an error occurs, remove the battery from the respective
output and re-press the START/STOP button to shut off the
alarm. At this point the output will be reset back to idle mode
with the LED flashing green. Refer to the Troubleshooting
Guide for further information.

The PolyCharge4 charger uses solid-state circuitry to protect
against potential damage which could be caused by a short-
circuit or reverse polarity conditions.

CURRENT OVERLOAD: if for some reason a short circuit
condition exists which will try to draw more than 20 amps
through the charger’s input lead, the built-in fuse should blow.
To check the fuse, make sure the charger is disconnected
from the input power source BEFORE attempting to remove
the fuse. Inspect the fuse and replace if necessary with
another fuse of the same rating (20A, 32V).

REVERSE INPUT POLARITY: if power is connected in
reverse to the charger’s input lead the charger will be
protected from damage. Re-check the input connections and
the power source to ensure the proper power and polarities
are observed.

PROBLEM: Charger doesn’t recognize battery.
CAUSES AND CURES:

1. Battery may be connected backwards. Connect battery

leads properly.

2) Faulty connection or wiring. Correct or replace charge lead.
3) Defective cell in the pack. Replace battery pack or cell.
4) Insufficient input power to charger.

PROBLEM: Charger does not automatically terminate charge

after 3 hours.

CAUSE AND CURE: Capacity setting too low for respective

port and battery. Reset capacity dial to better match the
battery and start charge again.

PROBLEM: Battery voltage low after charge (below 4.2V per
cell).
CAUSES AND CURES:

1) Battery in poor condition. Replace battery.
2) Automatic safety timer activated before battery reached

full charge. Reset capacity dial to better match the
battery and start again.

3) Power supply voltage too low. Adjust DC input voltage to

12.0V DC minimum.

4) Battery connected in reverse. Connect battery

leads properly.

5) Defective battery needs to be replaced.

PROBLEM: LEDs and controls do not function properly.
CAUSE AND CURE: Battery possibly connected backwards.

Connect battery leads properly, or contact Hobby Services
for further details.

PROBLEM: LEDs do not work when unit is connected.
CAUSES AND CURES:

1) Check power supply for improper power.
2) Check input connections for proper contact.
