Maintenance
Warning: Disconnect power before servicing.
1. Using a clean, dry cloth, wipe the gate opener shaft, and then apply a silicone spray to reduce its friction.
In cold climates where temperatures reach 1°C (30°F) or less, spray silicone on the actuator every 4~6
weeks to prevent freeze up.
2. Regularly check gate hinges to make sure gate is swinging smoothly and freely. Grease hinges if
needed.
3. Check your installation periodically, as hardware and posts will shift. Brackets may need to be adjusted
or hardware may need to be tightened.
4. Maintain the area around your gate. Keep the areas free of objects that can prevent the gate swinging
freely.
NOTES:
1. Inspection and service should always be performed anytime a malfunction is observed or suspected.
2. It is suggested that while at the site voltage readings be taken at the operator. Using a Digital Voltmeter,
verify that the incoming voltage to the opener it is within ten percent of the opener’s rating.
3. Refer to Page 21 for instructions on how to check gate force and sensitivity adjustments.
Trouble Shooting
1. Opener does not run. Digital Display indicator is not on.
Check if all motor are properly connected and color coded. Make sure the AC input is connected.
Check if the fuse in control board is bad.
2. Opener powers up but does not run.
Arm cable loose or disconnected. Verify that all of the wires going to the arm are secure and that the
connector is properly mated to the header.
Arm is incorrectly installed. Disconnect the motor housing from the arm and verify that the arm moves
freely.
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.
Bad control board. Call technical support for help with replacement parts.
3. Gate stops immediately after it starts moving.
Obstruction sensed. Check safety devices and gate for obstructions.
Force set too low. Adjust FORCE setting until gate completes a full open/close cycle without stop. The
force setting may need to be adjusted in cold weather, as the gate will not move freely.
Check if the MRT period is too short. Refer to page 21.
Incorrect power.
4. Gate opens but does not close.
Photocell (PBS) is set in Control Board but is not equipped (optional). Please cancel the PBS set. Refer to
page 22.
Obstruction blocking close photo eyes, Check eyes for alignment and verify all connections and operation
for safety devices.
5. Gate ignores the limit switches
Check that the limit switch is not faulty
Check that wires to the limit switch are not shorted.
