The Relay Box Installation
Relay Box Wiring
A 6.3 amp 250v fuse protects each relay. Four spare fuses along with LED fuse test
indicators are located at the bottom of the relay board. (Fuses should not be replaced
with any other device.)
Another approved, ¾” conduit needs to be run to your motor control center to the Relay
Box and will contain the low voltage wires for clock (Pulse), gate (Entrance switch) and
Tire switch functions.
When using a normally open 2-wire pulse switch, use terminals marked CLK SINK and
PROX GND. (See Pulse switch wiring diagrams)
When using a normally open 3-wire pulse switch, use terminals marked PROX PWR,
CLK SINK, and PROX GND. (See Pulse switch wiring diagrams)
Gate inputs and Tire inputs require a constant 24vac neutral supplied from a class 2
transformer. The hot signal would be terminated to the normally open pole of the
electric eye (gate) switch. (See wiring diagrams for Gate Switch and Tire Switch)
Panic circuit inputs requires a constant 24vac neutral supplied through the stop/start
circuit. (See wiring diagrams for Panic Circuit options)
