illuminated.
Ensure drive train rotates
freely.
Ensure motor rotates
freely when turning the
motor shaft by hand from
the brake end.
Verify correct
counterweighting.
Motor connector not
properly installed/seated.
Measure battery voltage
on B12 and N12
terminals.
Verify correct
counterweighting.
Verify gate ascent time is
programmed a higher
value than intended.
Verify correct
counterweighting.
Verify gate descent time
is programmed a higher
value than intended.
Action
1) Remove any obstructions.
2) Ensure the wind guard is
Ensure internal reduction gearing
rotates freely without binding or
drag.
1) Secure gate position with the
2) If drag or binding is present,
Adjust as necessary to achieve
proper horizontal torque.
Ensure motor connector is fully
inserted into the control board.
Replace the Control Board
Ensure a minimum of 11 VDC is
sustained at all times on terminals
B12 and N12 while the gate is
ascending.
Adjust as necessary to achieve
proper horizontal and vertical torque
values.
Refer to the programming section of
this manual and reprogram the Gate
Ascent time to the desired rise time.
Adjust as necessary to achieve
proper horizontal and vertical torque
values.
Refer to the programming section of
this manual and reprogram the gate
descent time to the desired fall time.

parallel to the gate arm and not
binding.
Lock Bar in the "Keep Up"
position. Unplug and unbolt the
gear motor and remove the
pinion gear from the reduction
gear to check the free rotation
of the gear motor
