POSSIBLE REMEDIES TO CHARGE CONTROLLER ‘FAILURES’
WRONG BATTERY VOLTAGE
Charger connected to a 24v battery. Reconnect to a battery
rated at 12Vdc.
REVERSE BATTERY
CONNECTION
Check and correct any reverse battery.
THERMAL RUNAWAY
CONDITION
Old Battery - cells, inside battery, age differently. During
charging, and over the course of many years of operation,
OR, many battery discharges to levels beyond 100%
discharged, this error may occur and the battery(s) may have
to be replaced.
CHARGE TIME MONITOR –
1 and 2
Battery pack took too long to complete its charge. Possible
causes include a load (gate cycling repeatedly for a long
period of time) during charging or the battery pack is too
large (Many batteries connected in a parallel circuit). Apply
the following formula to determine if the Timer may run out
due to a large battery:
Charge Time
= Battery Capacity (AH) x 1.25
2
Calculated Charge Time must be less than approximately
108hrs.
Output Amps and Battery Capacity (AH - Ampere-hour) are
listed on your battery or contact your battery purchasing
source.
Example: Charge time to for a fully discharged 36 AH battery:
36AH / 2 Amps x 1.25 = 22.5 Hrs - ok to use.
EXCESSIVE BATTERY DRAIN
Excessively high number of cycles discharging the battery
beyond point of no return. Stop gate, and allow battery time
to recharge.
PRE-QUALIFICATION TEST -
1 and 2
During Battery testing, if a battery was previously allowed
to discharge to a very low voltage, such as 1 or 2Vdc, the
charger puts a low current through the battery to try to get
the battery to come back to life. The battery may be taking
too long to come back.
NO POWER ON CHARGER
Check the transformer Supply Adaptor Plug-in, or the Solar
Panel for proper connection.
