PROBLEM
Low Battery
A
Voltage Condition
(STATUS light flashes 3 times)
POSSIBLE CAUSES & SOLUTIONS TO PROBLEM
(If the battery voltage is less than 10.5V, the motor would not
operate at all. For any other voltage, the battery could still be the
cause of the problem.
Check that the power is turned ON, by first disconnecting
the battery and then to check that the green CHARGE light is
ON. If it is OFF, then power is not connected to the charger or
the power pack.
Check that the power source link is in the STD position
when using the CP84E charger, and in the PSUx (10A power
pack) driven installations.
Check the condition of the battery leads, terminals and
connectors. Look for and correct all loose connections and
signs of corrosion.
The battery might be discharged. Measure the battery
voltage with the charger connected, if the voltage is below
12.5V then the battery is discharged. The number of opening
cycles per hour may be excessive, thus discharging the
battery. Charge the battery, or fit a 10A power pack if
required.
Charger might be faulty. Disconnect the battery, and
measure the voltage on the battery leads. It must be between
13.6V and 13.8V, if not replace the charger.
Battery might be old, and might have to be replaced. If in
doubt test as follows:
Check that the battery is charged, by ensuring that
the battery voltage is above 13.5V with the charger
connected. (If the battery is in a good condition it
would probably pass the test without being fully
charged)
Disconnect the charger from the battery
Remove the DC Motor leads from the DC Controller
Apply the DC motor leads directly to the battery,
while measuring the battery voltage. WARNING: First
make sure that the moving gate will not pose any
danger.
If the gate does not move, the battery or motor
could be faulty.
If the battery voltage remains unchanged, then the
motor is faulty and must be serviced. If the battery
voltage drops to below 11,5V then the battery must
be replaced.
(Before replacing the battery, measure the charging voltage on
the battery leads with the battery disconnected. It must be
between 13.6V and 13.8V, if not, replace the charger.)
