2-3. Set the 9 Pole, 3 Pos t on Cod ng Sw tch on the Receiver to
match the Transmitter’s 9 Pole, 3 Pos t on Cod ng Sw tch. Any
switch position will work as long as the Transmitter cod ng sw tch
and the Receiver cod ng sw tch are exactly matched (must be
different from other nearby transmitters of the same type).
2-4. Place the two (2) AA batter es in their holders on the Transmitter
in the proper direction, paying attention to the (+) and (-) ends.
Momentarily press the Test Button on the Transmitter.
The Green Tx LED Ind cator should light for 3 seconds.

2-5. Route the wires from the safety edge through
the Transmitter’s Stra n Rel ef Cable F tt ng for
approximately four inches.
2-6. Strip the insulation from the two wires back ¼”. Pull the
Term nal Block off the Transmitter’s PCB. Place the safety
edge wires in the Term nal Block and tighten with screwdriver.
Re-seat the Term nal Block on the PCB (see Fig. 2-6).
2-7. Re-seat the PCB into the Transmitter Enclosure and securely
tighten the Stra n Rel ef Cable F tt ng.
2-8. Now, compress your safety edge. The Green Tx LED Ind cator

3- Install Receiver and Test
3-1. Set the 9 Pole, 3 Pos t on Cod ng Sw tch on the Receiver to
match the Transmitter’s 9 Pole, 3 Pos t on Cod ng Sw tch. Any
switch position will work as long as the Transmitter cod ng sw tch
and the Receiver cod ng sw tch are exactly matched (must be
different from other nearby transmitters of the same type).
3-2. Mount Receiver inside the operator control box so that the wires
from the receiver will reach the terminal strip on the operator.
3-3. Wiring:
a. The red (+) and black (-) wires are your power leads. They
connect to your operator panel terminals that provide the
appropriate power (12-24 VAC/VDC). Black wire is common,
Red wire is (+) or AC power.
b. The green wire is your standard antenna wire. This must be
located outside of any metal enclosure to provide for good
signal reception. There is an F-Connector antenna fitting
included on the receiver in the event a remote antenna
placement is needed.
c. Receiver Connections: The white wire will go to your
operator’s low voltage common terminal. If your operator
requires a normally open (N.O.) contact, connect the
yellow wire to the operator’s safety edge input. If the
operator requires a normally closed (N.C.) contact,
connect the orange wire to the operator’s safety edge input.
3-4. Preliminary Test:
Confirm that once power is applied to the Receiver, it’s green
LED is lit. Now press the Transmitter's test button and notice
that the red LED lights up on the Receiver and the green LED
lights up on the Transmitter.
3-5. Replace the Receiver Top Lid.
4- Safety Test
4-1. While closing the door or gate, momentarily activate the safety edge and confirm that
the motor stops and reverses the door or gate direction.
