The gate operator control board has a Fault Light to help determine fault shutdowns. If the operator is not functioning properly,
remove the cover and check the Fault Light for the operator Fault Status. Use the following chart to determine the Fault:

Sensitivity/Current Overload:
First Time
Cause & Action
Operator detected an unexpected current overload while moving. Usually caused by the gate
hitting an obstruction or tripping the sensitivity. This will put the operator in a Soft Shutdown.
1. Make sure the sensitivity settings are set correctly. Too light of a setting will cause the
gate to stop and fault.
2. Make sure there are no external obstructions that are causing the gate to stop and
shutdown.
Operator detected an unexpected current overload while moving a second time. Usually
caused by the gate hitting an obstruction or tripping the sensitivity. This will put the operator
in a Hard Shutdown.
1. Make sure the sensitivity settings are set correctly. Too light of a setting will cause the
gate to stop and fault.
2. Make sure there are no external obstructions that are causing the gate to stop and
shutdown.
Operator has run longer than normal. Usually caused by a bad limit or limits being miswired.
1. Check the limit for normal operation.
2. Make sure the limit wires are tight and wired correctly.
Motor Sensors have failed. Usually caused by a bad sensor or loose sensor wire.
1. Make sure the sensor wires are tight and well connected to the blue connector. While the
operator is stopped, wiggle the Limit/Sensor connector. If the limit or sensor wires blink on
and off, there is a loose connection.
2. Start the operator, watch Sensor 1 and Sensor 2 at startup. They should both blink before
turning solid. If only one blinks, then the non-blinking sensor is not being seen.
3. Remove the motor from the gearbox. Both sensor lights should be on. Pass a flat screw
driver between Sensor 1 and Sensor 2 on the motor plate. The Sensor LED on the control
board should turn off and on as the screw driver passed through it.
4. Make sure the sensor cup on the gearbox shaft is tight. There are set screws in the collar.
A loose sensor cup will slip and cause the sensors to miss counts.
Operator PCB has become too hot and caused a fault.
1. Make sure the control board heat sink is secured to the side of the controller box to help
dissipate excess heat.
2. Determine if the operator has run excessively to cause an overheating problem.
3. Possibly a defective heat sensor on the control board. Have board repaired.
Master Slave communication has failed. Usually caused by a loose Master Slave wire or
connector. A very strong lightning strike can sometimes cause damage to the master slave
circuit on the control board.
1. Make sure the master slave wires are connected correctly and tight.
2. Route the master slave wire up over the control box to help pull the connector tighter
against the top of the plug pins. Tightly routing under the controller can cause the
connector to pull away from the plug pins and cause intermittent faults.
3. Unplug the master slave wire and set both operators as Masters. Test each operator
independently to make sure there are no other problems or faults. After determining each
operator runs by itself, reset the master slave settings and connect the master slave wire.
If the problem continues, recheck wire and wire connections.
4. Run a new CAT5 wire on top of the driveway to test the master slave communication. This
will determine if the underground wire is good or bad.
5. Possible damage to the control board master slave components. Have boards repaired.
