3.3 Limit Sensors
Loosen set screws to
adjust the limit sensors.
Make sure set screws are
tightened after adjustment.
Magnetic sensor activator
must be directly above the
limit sensor to activate it.
The hub
must not slip
during operation. Tighten
bolt to stop any slipping.
CAUTION
DO NOT REMOVE HUB!

Important Limit Sensor Adjustment Note:
It is very important
NOT
to cycle the gate operator before the limit sensors are in
the correct position or it could cause damage to the gate and operator.
Turn
ON AC power
. Manually release the gate operator hub with the release tool
(See page 30). Physically move the gate to the desired open position. Loosen the
set screw on the
OPEN
limit sensor and slowly slide it under the magnetic sensor
activator until the
OPEN
limit Sensor LED lights up on the circuit board. Tighten the
set screw and repeat this process for the close gate position. Secure the hub with
the release tool and cycle the operator a few times and readjust if necessary.
