Troubleshooting
WARNING
! Turn the main power off before you make any electrical connections
or set any switches inside the operator.
If you have a problem installing the operator, check the
problems and solutions listed below.
Problem: The operator does not respond to the
activating signal.
Solutions:
Make sure the main power switch is on.
Make sure the Open LED is not steadily illuminated. If
it is, remove all wires from terminal 2 to see if that turns
off the Open LED. If the Open LED goes off when you
unwire terminal 2, check your activating devices.
Check the control panel terminal strip for possible
broken or disconnected wires.
If a radio signal is being used to activate the operator,
be sure the code sets on both the transmitter and
receiver are the same.
Momentarily short across terminals 1 and 2 on the
control panel. If this activates the operator and if the
Open LED illuminates, a problem probably exists in the
activating device itself.
Problem: The gate is closed and does not open.
Solutions:
Make sure the clutch adjustment is not too weak.
Increase the torque if the motor is running and the gate
is not moving. This may be necessary for especially
heavy gates.
Check that the closed limit switch is working. The FCC
status light should be off and the FCA LED should be
illuminated. If the FCA LED is not on, the gate leaf has
traveled too far in the closing direction.
Make sure that the Manual Release is not preventing the
operator from working.
Check fuse F1 and replace it if necessary.
Problem: The gate opens, but will not close.
Solutions:
If there are no optional reversing devices connected to
the control panel, make sure a jumper is installed
between terminals 1 and 4 of the control panel.
If optional reversing devices have been installed, check
them to see if they are working properly (an activated
reversing device will prevent the gate from closing).
Temporarily short across terminals 1 and 4 to bypass
the reversing devices to see if the gate closes. If the gate
closes and if the FTSW LED illuminates, then the
problem exists within the reversing device(s).
Problem: The gate opens and the operator continues
to run.
Solutions:
Check the FCA light on the control panel. It should be
off. If it is not, check the alignment of the limit switch
plate.
If the FCA light is not off and the limit switch plate is
correctly adjusted, then replace the limit switch.
Note:
If the limit switch plates are not detected by
the limit switch, the operator will run for
approximately 120 seconds and then stop. You will
have to reset the control panel if the motor
completes its maximum run time. To reset, either
cycle the main power off and then on, or press the
Reset button on the control panel.
