Owner`s manual

Gate opens a short
distance, then
stops and reverses.
• Disconnect the gate from the gate operator and check that the gate slides freely without
any binding.
• Re-adjust the open reverse sensitivity.
• 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 2 is ON.
• Check motor as described on previous page.
Gate closes but will
not open.
• Operator may be in a “soft shutdown.” Check input LED on terminal 5. If it is ON,
momentarily disconnect, then re-connect the wire going to the 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 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.
Gate starts to
close, then
reverses to open.
• Re-adjust the close reverse sensitivity.
• 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.
• 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).
Entrapment alarm
is sounding.
Operator will not
run.
• Operator is in a “hard shutdown” condition. Reset switch must be activated to return
operator to normal operation.
• Check gate and gate hardware for any binding – correct where necessary.
• Gate may be too heavy.
Entrapment alarm
sounds a short
beep every 5
seconds.
• Operator has been in a “hard shutdown” condition in excess of 5 minutes. Reset switch
must be activated to return operator to normal operation.
Entrapment alarm
activates when
power is applied
and operator will
not run.
• The limit switch wire harness is not plugged into the circuit board. Check that the limit
switch connector is properly plugged into P2 on the circuit board.
Operator runs for 1
second and stops,
two short beeps
are heard.
• There may be a problem with the current sensor on the circuit board. Replace the circuit
board.
