INS./OUTS. INT. SENSE / SHADOW SENSE / EXIT SENSE (TB12/TB13/TB14/TB15) INPUTS
INSIDE Input from an Inside Interrupt loop provides the signal for an optional
LiftMaster INTERRUPT loop detector add-on board. Operation is the same as the
Interrupt Loop SENSE input, above.
OUTSIDE Input from an Outside Interrupt loop provides the signal for an optional
INTERRUPT LiftMaster loop detector add-on board. Operation is the same as the
Interrupt SENSE Loop input, above.
SHADOW
Input from shadow loop provides signal for optional LiftMaster loop detector
SENSE add-on board. Operation is the same as Shadow Loop input, above.
EXIT Input from exit loop provides signal for optional LiftMaster loop detector add-
on SENSE board. Operation is the same as Exit Loop input, above.
RADIO INPUT (TB6)
RADIO RECV Convenience terminals provide power (24VAC, 200mA) and signal
connection for a radio receiver. Activation is the same as CYCLE.
MAG LOCK INPUT (TB4)
MAG LOCK NO and COM inputs can close a circuit (i.e., MagLock) when the Close Limit
switch is activated (the gate is fully closed).
NC and COM inputs close a circuit (security camera, camcorder, light, etc.)
when the Close Limit switch is deactivated (when gate is not fully closed).
SLAVE I/O INPUT (TB1)
SLAVE I/O Input/output terminals are used to control a second gate operator in a
Master/Slave system.
ADJUSTMENTS
OVERLOAD Factory-set pot protects the gate operator from excessive motor current.
(R71) If RETRY is ON, when the limit is exceeded, a closing gate reverses a few
inches and stops, and an opening gate stops, waits 30 second, then tries to
resume. The gate will retry twice before faulting out.
NOTE: Gate may be more sensitive to drag in one direction than the other.
NOTE: For swing gate operation, controls are Right/Clockwise and Left/Counterclockwise.
REVERSE Adjustable pot controls gate sensitivity to blockages by the instantaneous
RIGHT (R78) rise in motor current. If RETRY is ON, when the limit is exceeded, a closing
gate opens fully and an opening gate stops, waits 30 seconds, then tries to
resume. The gate will retry twice before faulting out.
REVERSE Adjustable pot controls gate sensitivity to blockages by the instantaneous
LEFT (R81) rise in motor current. If RETRY is ON, when the limit is exceeded, a closing
gate opens fully and an opening gate stops, waits 30 seconds, then tries to
resume. The gate will retry twice before faulting out.
NOTE: LiftMaster gate operators have two reverse sense adjustments (left and right)
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.
INRUSH Adjustable pot controls the delay in sensitivity to a reverse sense input.
(R119) This delay in sensitivity prevents the initial motor inrush current from
causing a fault condition. The weight of the gate determines this setting.
RECLOSE Adjustable pot controls the time delay between gate reaching full open and
TIMER (R94) starting to reclose. The Reclose Timer is adjustable from 0-250 seconds.
