Establish what the gate opener is doing or not doing:
This is the most important step. You should identify something that is happening. All too often
we hear someone say that it is not doing anything - the reality however is the gate opener is
always doing something. The motors may not move but the display may change or there may
be a clicking noise, however it is very rare that there truly is nothing at all that is
happening. Also sometimes we hear about intermittent issues. Wait for the issue to be currently
occurring and then use the definition of that issue to be what is happening.
Things that could be happening and what the issue is:
The motor won’t move and it displays LU on the display.
LU means low voltage. The battery voltage should be above 12.4 VDC. If the battery drops be-
low this then the system will show LU and the battery should be charged.
Other possibilities of LU are:
The wire leading from the battery to the control board has a switch, fuse or diode on it. We
do not provide a switch, fuse or diode however some individuals utilize these on their wires
leading to the board. This can cause the board to not read the battery correctly.
The battery size is too small. The minimum battery size the system can detect is 12V 7a/h. If
the battery is smaller it will not detect the voltage of the battery correctly.
The logic chip on the board has suffered an electrical pulse and is no longer reading the
battery correctly. In order to verify this is the issue you must follow this process:
a. Disconnect the battery from the control board and from the charging source (solar
panel or transformer)
b. Disconnect the large Red and large Black motor wire from the control board termi-
nals L1-1 and L1-2
c. Take the ends of the wires that normally attach to the control board from the batter-
ies and attached them to the prongs of a multi-meter set to DC voltage.
d. Read the battery voltage through the wires and ensure this voltage is above 12.6
volts
e. Take the red and black wires from the motor and touch them directly to the battery
terminals. This will cause the motor to run. The polarity of the red and black motor
wires on the battery positive and negative will cause the motor to extend or retract.
Swap polarity to cause the opposite reaction from the motor.
f. While the motor is running look at the multi-meter reading again. The voltage should
not drop more than 0.2 volts
g. If all the above are true then we can rule out battery and wire from battery to board
and determine the chip needs to be replaced.
