Motor cable wire not connected. Make sure that all the motor wires are connected
properly.

Motor housing is not properly seated. Make sure that the motor housing for the
arm(s) is properly seated so there are no gaps between the motor housing and arm
assembly. Make sure all 4 screws are tightened.

•
Arm is interfering with the gate mount bracket. Examine the hinge point where the
arm mounts to the gate post. Make sure that the arm housing does not hit or
interfere with the gate post or mounting bracket throughout the full length of travel.
Adjust the arm mounting and positioning if necessary.
•
Gate is excessively heavy or hinges are bad. Verify that the gate is within the ratings
for this product. Disconnect the arms and verify that both gates swing easily.
Lubricate or replace hinges as necessary.

STOP button connection loose or disconnected. Press the RESET button and verify
that the STOP LED lights up and then turns off after 10 seconds. Verify the wire

Force set too low. Adjust FORCE setting until gate completes a full open/close cycle
without reversing. The force setting may need to be adjusted in cold weather, as the
gate will not move freely.
•
Loops are reversed. Make sure that the Safety loop and Shadow loop are
connected properly. The gate may trigger the Shadow loop as it moves, so it must
be connected to the correct input.
•
Low or defective battery. At least one charged battery must be connected for the
units to operate. Verify battery fuse is intact. Check battery connections and battery
voltage to be above 11.5V. Replace batteries if necessary.
