Gate opens a short
distance, then
stops and reverses.
• Disconnect the gate from the actuator and check that the gate swings freely without any
binding.
• Check the reverse sensitivity.
• Check the secondary safety devices.
• Replace the circuit board.
Gate opens but will
not close.
• Check the input LEDs. Any ON will hold the gate open and indicates a problem with a
keying device.
• Check the secondary safety devices. Any activated will hold the gate open and indicates a
problem with the safety device.
• Check the loop detectors. Any activated can hold the gate open and indicates a problem
with the loop detector or ground loop.
• Operator may be in a “soft shutdown.” Activate any keying device to determine if operator
returns to normal operation.
• If automatic close is desired, be sure SW-1, switch 4 is ON.
Gate closes but will
not open.
• Operator may be in a “soft shutdown.” Check input LEDs. If any are ON, momentarily
disconnect, then re-connect the wire going to the input terminal. Actuator should open.
• Check to be sure that the actuator is running in the proper direction. Turn power OFF,
disconnect batteries and solar panels, and then back ON. Activate a keying device.
Actuator should run in the open direction. If actuator runs in the close direction, turn power
OFF and change direction switch SW-1, switches 1 and/or 2. Re-test and reconnect
batteries and solar panels.
• Be sure that the respective LED on the control board lights when the keying device
connected to the respective terminal is activated. If LED does not light, momentarily place
a jumper wire from terminal 1 to the input terminal being checked. If LED lights and gate
opens, problem is with the keying device. If LED does not light, replace control board.
Gate starts to
close, then
reverses to open.
• Disconnect the gate from the actuator and check that the gate operates freely without any
binding.
• Check the loop detector LEDs and input LEDs. Any that flash ON will cause the gate to
reverse.
• If a shadow loop is used, check for proper wiring. A mis-wired shadow loop detector will
cause the gate to reverse.
• Replace the circuit board.
Gate closes and
then re-opens.
• Check for any input or loop detector LEDs that are ON.
• Check that the operator is running in the proper direction (see “gate closes but will not
open” above).
Alarm sounds for 5
minutes and then
beeps once every 5
seconds. Operator
will not run.
• Operator is in a “hard shutdown” condition. Reset switch must be activated to return
operator to normal operation.
