NOTE:
The Obstruction Sensitivity /Stall Force is adjustable in 9 levels.
With the gate in its opened position, press and release the remote control, the gate will move to the programmed
closing position and stop.
While the gate is moving, press and release the remote control, the gate will stop moving immediately. The next
command from the remote will reverse the gate direction and the gate will stop at its programmed opening/closing
position.
The gate will stop in case of obstruction during opening. The command from the remote control will reverse the
gate direction and the gate will stop at its programmed closing position.
The gate will reverse in case of obstruction or stall force during closing, and it will move to the programmed
opening position.
Maintenance
Warning: Disconnect power before servicing.
1. Using a clean, dry cloth to 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 the instructions on how to check gate force and sensitivity adjustments.
Trouble Shooting
◆
Opener does not run. Digital Display indicator is not on.
1. Check if the power is on. Check the input voltage at the terminal. It should be local AC power. If the voltage
measures 0 suing the voltmeter, the power cable may be damaged.
2. Check if the output voltage of the transformer is 24Volts AC. If the voltage measures 0, the transformer may
be overheated or damaged. Turn power off and allow transformer to cool for several minutes then reset.
Replace the transformer if the symptom still exists.
3. Check the fuse in the control board. Replace the fuse if necessary.
◆
Opener powers up but does not run.
1. Check if the arm cable is loosening. Verify that all of the wires of the arm are secure to the terminals of the
control board.
2. Arm is incorrectly installed. Disconnect the motor housing from the arm and check if the arm moves freely.
3. Gate is excessively heavy or hinges are bad. Check 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.
4. Bad control board. Call technical support for help with replacement parts.
◆
Gate stops immediately after it starts moving.
1. Obstruction sensed. Check safety devices and gate for obstructions.
