Convenience terminals provide power and contact connection for a
radio receiver. Activation is the same as CYCLE.
Relay contacts close to provide 24VDC alarm power if the gate has two
consecutive obstruction faults.
Activation fully opens or closes the gate, depending the setting of
Switch S3.
Activation registers the date and time of power outages in the gate
operator transaction buffer.
Terminals provide power (24VAC, 200mA) for peripheral
Relay contacts close when the gate is fully closed.
Input/output terminals are used to control a second gate operator in a
Master/Slave system.
Adjustable pot controls gate sensitivity to blockages by the
gate reverses a programmed distance (minimum 2 inches).

where other gate operators have only one. This allows greater flexibility
of installation. For instance, you can install a gate on an incline and not
worry about sacrificing downhill gate sensitivity.
Adjustable pot controls the delay in sensitivity to gate
obstructions. This delay in sensitivity prevents the initial motor
inrush current from causing a obstruction fault. The weight of the
determines this setting.
