Contacting Technical Support
For technical questions regarding Linear gate operators, contact the
Technical Services Department at:

Operator fails to start
A. Make sure you have power at the master distribution
panel and that the power has not been turned off.
B. If the “Reset to Factory Defaults” (CL) programming step
has been used, ensure the motor type (MO) has been
set to d2 and open (OC) and closed currents (CC) have
been set.
Motor operates, but gate does not move
A. Make sure all mounting hardware is still attached and
that all fasteners are tight.
B. Check that the actuator worm gear is moving. If it isn’t,
the gears in the drive may have stripped.
Motor sounds like it is working harder than normal
A. Make sure the gate is moving freely and without binding
throughout its entire travel.
Gate stopping part way open or closed
(but no visible obstruction)
A. The Controller may have received a false obstruction
input triggered by current sensing set too low. Make sure
the gate moves freely through its entire travel before
adjusting the current sensing.
B. The Maximum Run Timer may have counted down and
expired. This can be caused by having the timer set
too low. When the timer expires, the gate stops and the
beeper will sound.
C. An obstruction signal from an accessory wired to the
obstruction input may have triggered falsely. Check the
control board for lit indicators for any of the following
inputs: safety, shadow/reset, open obstruction, close
obstruction, stop, etc. If any are lit when the operator
should be running, remove all devices hooked to that
function and hook them up one at a time and try to run
the operator until the problem device is found. Refer to
Page 8 for details on the control board indicators.
Gate staying open with automatic system
A. If there are vehicle detectors used with the operator, one
of the loops or loop detectors may be sending a false
signal or needs to be reset. Observe the indicators on
the loop detector. Unplug the detector and try running
the operator.
B. An opening or reversing device may be stuck or
malfunctioning. Try disconnecting these devices and
hook them back up one at a time and try running the
operator until the malfunctioning device is found.
