6.3 Magnetic Limit Adjustments
The operator has been preset at the factory to rotate 90°. No adjustments are necessary when used in a normal 90° setup.
If the arm needs to rotate less than 90°:
1
Turn operator power OFF.
2
Set the DIP-switch SW 1, switch 3 to ON.
This changes the rotation of the gearbox
from 360° to 180° allowing the gearbox
to rotate the arm less than 90°.
Note: The arm will always cycle to 90°
open with the 360° gearbox setting.
3
Loosen magnet limit assembly nuts and slide the
assemblies to the desired UP and DOWN positions.
Tighten nuts when desired positions are achieved.

6.4 Reverse Sensor
Reverse sensitivity adjustment will cause the barrier arm to reverse direction of travel should an object be encountered during
the down cycle. The amount of force required for the arm to reverse direction depends on the reverse sensitivity potentiometer.
CAUTION: Keep pedestrians and vehicles clear of the arm zone while adjusting sensor!
While operator has AC power:
1
Turn control switch to UP. Arm will rotate UP.
2
Turn control switch to DOWN. While arm is
traveling down, rotate reverse sensor clockwise
until the
reverse LED lights up
reverses direction. Rotate reverse sensor back
counterclockwise approximately 1/8 turn.
3
Repeat the adjustment as needed to find a
satisfactory setting.
