• 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 2 is ON and set timer open from 1-23 seconds.
• Bypass circuit board and check motor as above.
Gate opens but
will not close.
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 respective terminal. Operator should open.
• Check to be sure that the operator is running in the proper direction. Turn power OFF, and then back ON.
Activate a keying device. Operator should run in the open direction. If operator runs in the close direction, turn
power OFF and change direction switch SW 1, switch 1. Go to above section if operator now opens but will not
close.
• Be sure that the each LED on the control board lights when the keying device connected to the that 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.
• Bypass circuit board and check motor as described above.
• Disconnect the gate from the gate operator and check that the gate slides freely without any binding.
• Re-adjust the reverse sensitivity.
• Continue troubleshooting or replace circuit board.
Gate opens a short
distance, then stops
and reverses.
Gate closes then
re-opens.
Gate starts to close,
then reverses to open.
Operator runs for 1
second and stops, two
short chirps are heard.
Alarm chirps once
every 5 seconds.
Operator will not run.
Alarm is sounding.
Operator will not run.
Alarm sounds when
power is applied and
operator will not run.
• Re-adjust the reverse sensitivity.
• Disconnect the gate from the gate operator and check that the gate slides freely without any binding.
• Check the loop detector LEDs and input LEDs. Any that flash ON will cause the gate to reverse.
• Continue troubleshooting or replace circuit board.
• Operator has been in a “hard shutdown” condition in excess of 5 minutes. Reset button must be
pushed to return operator to normal operation, see Section 6.2 Shutdown Conditions, page 34.
• The limit switch wire harness is not plugged into the circuit board. Check that the limit switch connector is
properly plugged into the limit switch plug on the circuit board.
• There may be a problem with the current sensor on the circuit board. Replace the circuit board.
• Operator is in a “hard shutdown” condition. Reset button must be pushed to return operator to normal
operation, see Section 6.2 Shutdown Conditions, page 34.
• Check the gate and gate hardware for any binding, correct where necessary.
• Gate may be too heavy.
• Check for any input or loop detector LED’s that are ON.
• Check that the operator is running in the proper direction (see “gate closes but will not open”).
Symptom Possible Solution

• Check that AC power to the operator is turned ON.
• Transformer may be overheated. Turn power off and allow board to cool for several minutes then retest. Check
for low VAC power and low voltage shorts.
• Check for VAC at high voltage input terminal. If voltage measures 0, check the incoming power wires or
replace the circuit board.
Operator will not run.
Power LED is OFF.
