Probable Causes
1. Short circuit at terminals 11 and 13.
2. Short circuit at any of the loop detectors in
the board.
3. Short circuit in the control board.
1. Excessive current draw at terminal 13.
2. Over-voltage at the 110 Vac line input.
1. Motor thermal fuse has popped-out
(Rapid Flashing).
OR
2. One limit switch is faulty (Rapid Flashing).
1. Gate has encountered an obstruction during
traveling.
2. Reverse sensor is extra sensitive.
1. Gate encountered an obstruction during
traveling.
2. Alarm sensor is extra sensitive.
1. There is a command hold active.
1. There is a command holding the gate open.
1. Gate has reopened because it encountered
an obstruction while closing.
1. Gate has encountered two consecutive
obstructions while trying to close or open.
1. The loop detector needs to be reset.
2. The wire loop has been disrupted.
3. The loop detector needs to work in a
different frequency.
4. The loop detector is too sensitive.
1. Remove the short circuit condition at the
terminals.
2. Remove the defective loop detector.
3. Send the board to repair.
1. Reduce the accessories load from surge
suppressor terminal 13.
2. Verify your electrical power.
1. Reset the motor.
OR
2. Test the limit switches and wire connections,
fix the fault.
1. Remove the obstruction.
2. Turn the reverse sensor switch
counter-clockwise a little more and try again.
1. Remove the obstruction.
2. Turn the alarm sensor switch counter clockwise
a little more and try again.
1. This is a normal response of the gate operator. it
does not represent necessarily that there is a
problem.
1. This is a normal response of the gate operator. it
does not represent necessarily that there is a
problem. Check inputs for command.
1. Any re-new command will resume normal
operation. Check for obstructions.
1. Any re-new command will resume normal
operation but not a radio command. Check for
obstructions.
2. you can stop the alarm by using the built-in
reset button.
3. you can stop the alarm by using an optional
stop button.
1. Reset the loop detector (if you use Elite
Loop detectors, change the setting for sensitivity
and come back to your original setting.)
2. Verify and correct connections.
3. Set a different working frequency.
4. Decrease the sensitivity of the loop detector.
