•
Check the input LEDs. Any ON will hold the gate open and indicates a problem with a keying device.
•
Check the external 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 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.
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.
•
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 32.
•
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 32.
•
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”).

•
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 circuit board.
Operator will not run.
Power LED is OFF.
Operator will not run.
Power LED is ON.
•
Insure that a minimum of one (1) external entrapment protection device is connected in EACH entrapment area and the
inputs are connected and enabled (UL 325 DIP-switches are turned ON).
•
If a photocell is used as a external entrapment prevention device, check to be sure that the beam is not blocked.
•
Disconnect gate from the gate operator and check that the gate swings freely without any binding.
•
Bypass circuit board and Check Motor:
Turn power switch
OFF
and remove the circuit board. Place a jumper wire from
terminal
#18 to #17.
CAUTION – HIGH VOLTAGE.
Turn the power switch
ON
. The motor should run. Turn the power switch
OFF
and remove the jumper. With power switch still
OFF
, place a jumper wire from terminal #18 to #16.
CAUTION – HIGH
VOLTAGE.
Turn the power switch
ON
. The motor should run in the opposite direction. Turn the power switch
OFF
and
remove the jumper.
•
If the motor runs in both steps above, replace the control board. If the motor does not run, or runs in only one direction,
problem can be a bad motor, motor capacitor, motor resistors, wire connections from the control board to the motor or a
bad control board.
•
Disconnect the gate from the gate operator and check that the gate swings freely without any binding.
•
Re-adjust the reverse sensitivity.
•
Continue
troubleshooting.
•
Re-adjust the reverse sensitivity.
•
Disconnect the gate from the gate operator and check that the gate swings freely without any binding.
•
Check the loop detector LEDs and input LEDs. Any that flash ON will cause the gate to reverse.
•
Continue
troubleshooting.
Operator will not run,
entrapment protection
input(s) LED is ON.
•
The entrapment protection device is not connected or the wiring to it is open.
Operator will not run,
entrapment protection
input(s) LED is Blinking.
•
The entrapment protection device has a fault or the wiring to it is shorted.
Operator has intermittent
functionality problems
that vary.
•
The main terminal #3 250 mA power has been exceeded. Check total amp draw of connected device(s).
