| The arm moves but cannot | • Arm does not extend or contract enough during travel. The arm piston must extend | |
| exit Learn Limits mode. | and contract close to its full length to Learn Limits. Adjust the arm mounting so that |
|
| Cannot learn limits. | this can be achieved. |
|
|
| • 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. |
|
| Gate does not fully open or | • Over extending or contracting arm. Disconnect the motor housing from the arm and |
|
| close when trying to learn | make sure that the arm moves freely throughout the full length of travel. Adjust arm |
|
| limits. | mounting and positioning if necessary. |
|
|
| • 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. |
|
| Unit does not respond to | • Battery not connected. At least one charged battery must be connected for the unit |
|
| single button control (SBC) | to operate. Verify the battery fuse is intact. Check battery connections and battery |
|
| command. | voltage to be above 11.5V. Replace batteries if 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 |
|
|
| connects between STOP and CTRL PWR terminals. |
|
|
| • Single Button Control (SBC) button connection loose. Check wiring for SBC button. |
|
|
| Use the |
|
|
| • Bad control board. Replace control board. |
|
|
|
|
|
| Unit does not respond to | • Battery not connected. At least one charged battery must be connected for the unit |
|
| remote control command. | to operate. Verify battery fuse is intact. Check battery connections and battery |
|
|
| voltage to be above 11.5V. Replace batteries if 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 |
|
|
| connects between the STOP and CTRL PWR terminals. |
|
|
| • Radio module not plugged in. Verify the green Radio module (located next to the |
|
|
| coaxial connector) is properly mated with both |
|
|
| • Antenna not connected. Verify the antenna and coaxial cable are properly |
|
|
| connected to the control board. |
|
|
| • Remote control not learned. Refer to Programming Remote Control section for |
|
|
| steps to program the remote control. |
|
|
| • Bad control board. Replace control board. |
|
|
|
|
|
| Gate stops and reverses | • Obstruction sensed. Check safety devices and gate for obstructions. |
|
| immediately after it starts | • A fault has occurred. Check Diagnostic LED for possible error codes. |
|
| moving. | • 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. |
