•
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 described on previous page.
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 on previous page.
•
Check that the clutch is adjusted properly and is not slipping.
•
Disconnect the gate from the gate operator and check that the gate slides freely without any binding.
•
Re-adjust the reverse sensitivity.
•
Check that the magnetic pickup transistors on control board are not obstructed by excess wires.
Electrical interference from excess wires can diminish magnetic field.
•
Check that the magnetic pickup transistors on control board are within 1/8 inch of the clear plastic protective
cover above the black plastic magnetic spring assembly on the main shaft.
•
Contunue troubleshooting or replace the circuit board.
•
The entrapment protection device has a fault or the wiring to it is shorted.
Gate opens a short
distance, then stops
and reverses.
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.
Gate closes then
re-opens.
Gate starts to close,
then reverses to open.
Alarm chirps once
every 5 seconds.
Operator will not run.
Alarm is sounding.
Operator will not run.
•
Check that the clutch is adjusted properly and is not slipping.
•
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.
•
Check the Magnetic Sensor LEDs on the circuit board. If either LED is not blinking as the operator is running,
check that the magnetic pickup transistors are within 1/8 inch of the protective plastic cover above the magnet
assembly on the main shaft.
•
Contunue troubleshooting or replace the 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, pages 35-36.
•
Operator is in a “hard shutdown” condition. Reset button must be pushed to return operator to normal
operation, see Section 6.2 Shutdown Conditions, pages 35-36.
•
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 SW 1, switch 6 is OFF.
Operator has intermit-
tent functionality
problems that vary.
•
The main terminal #3 250 mA power has been exceeded. Check total amp draw of connected device(s).
•
The UL 325 terminal #5 250 mA power has been exceeded. Check amp draw of connected device(s).
