DESCRIPTION
REASON/SOLUTION
F06
The charger detected that the battery
may be getting too hot (thermal
runaway).
The charger automatically shuts the current off if it detects the
battery may be getting too hot. Have the battery checked or
replaced.
F07
The charger shut off because its internal
temperature exceeds limit.
Make sure the charger does not have the side ventilation holes
blocked. Move the charger out of the sun and into the shade.
F08
The battery voltage dropped too low
during the maintain mode.
May be caused by a drain on the battery or the battery could be
bad. Make sure there are no loads on the battery. If there are
remove them. If there are none, have the battery checked or
replaced.
F09
The Lithium Ion (LiFePO
4
) battery continues
to read 0 V and is unable to be charged.
The Lithium Ion (LiFePO
4
) battery could be bad. Have it
checked or replaced.
F10
The voltage on the Lithium Ion (LiFePO
4
)
battery exceeds the safe limit.
The charger automatically shuts off if it senses that the Lithium Ion
(LiFePO
4
) battery voltage exceeds the safe limit. The battery could be
bad. Have it checked or replaced.
If you get an error code, check the connections and settings and/or replace the battery.
Troubleshooting
PROBLEM
POSSIBLE CAUSE
SOLUTION
The battery is connected and the
charger is on, but is not charging.
The charger is not in charger
mode.
Press START/STOP button for the
battery that is connected to the
charger.
The indicator lights are lit in an
erratic manner, not explained
in the Operating Instructions
section.
A button may have been pressed
when the charger was plugged in.
Make sure nothing is touching the
control panel, then unplug the unit
and plug it in again.
The display shows CHARGE
ABORTED – BAD BATTERY and
an error code.
The charger was unable to
complete the charging of the
battery and is in abort mode. See
Error Codes for more information.
Disconnect and reconnect the
battery, or turn the power off and
then on, to reset the charger.
The charger is making an audible
clicking sound.
The charger has a relay that turns
the current to the battery on and off.
No problem, this is a normal
condition.
The measured current is much
lower than expected.
The charger reached the
maximum voltage and is reducing
the current.
The charger detected an over-
temperature condition and has
reduced the current to allow the
unit to cool.
No problem, this is a normal
condition.
Make sure the charger does not
have the side or rear ventilation
holes blocked. Move the charger
out of the sun and into the shade.
(Model DSR137): While charging
the battery, the battery stays at a
certain % (ex. <65%).
The % display may not change at
a steady rate.
DO NOT UNPLUG OR CHANGE
THE SETTING. Be patient and let
the charger finish. This is normal.
(Model DSR137): When the
charger is unplugged or the
settings are changed, the number
increases or jumps to 100%.
The battery voltage is still high
from a partial charge.
Wait for the voltage to settle before
resuming the charge. Turn on
the lights to remove the surface
charge.
