IMPORTANT: A clutch that is set too loose
will give false inherent entrapment
and reverse or stop the gate.

SOLENOID ACTIVATED, CALIPER
DISC BRAKE
The brake (Figure 5) minimizes overtravel
caused by gate coasting. An added
feature of the brake is to assist in
preventing backdriving of the gate.
The brake is spring applied whenever the
motor is not running. Anytime the motor is
running, the electric solenoid physically
releases the brake.
Important: periodically check and adjust
the brake mechanism. See page 31.
PRESSURE TYPE SLIPPING
CLUTCH
The operator clutch mechanism (Figure 6)
works similar to that of a clutch in a car. It
allows the operator to gradually start the
gate moving, rather than trying to
instantaneously start moving the gate.
This clutch mechanism must be adjusted
properly. During the installation of the
operator, you must tighten the clutch
spring lock nut so it is tight enough to
operate the gate, yet loose enough so that
if the gate meets an obstruction, the clutch
will slip easily.
This clutch system will require periodic
maintenance. See page 31.
WARNING
This friction clutch system is not an automatic reversing device. It only serves to minimize
damage to the gate operator and gate, and also to hopefully minimize vehicle damage. If you
need an external automatic obstruction sensing device, items such as gate edges and photo
beams are available to help protect pedestrians.
