•
Check the reversing sensitivity.
•
Disconnect the gate from the gate operator and check that the gate swings freely without any
binding.
•
Replace the circuit board.
Gate opens a short
distance, then stops
and reverses.
Alarm sounds for 5
minutes and then
beeps once every 5
seconds. Operator
will not run.
Symptom Possible
Solution(s)
•
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.
•
Check motor as described on previous page.
Gate opens but will
not close.
Gate closes but will
not open.
Gate closes and then
re-opens.
Gate starts to close,
then reverses to
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, switches 1 and/or 2. Go to
above section if operator now opens but will not close.
•
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.
•
Check motor as described on previous page.
•
Check that the reverse sensitivity is properly adjusted.
•
Disconnect the gate from the operator 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.
•
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).
•
Operator is in a “hard shutdown” condition. Reset switch must be activated to return operator to
normal
operation.
•
Check ERD setting.
•
Make sure operator hub does not slip when gate encounters an obstruction.
Gate will not reverse
when an obstruction
is encountered.
