2-1. Mount the Receiver inside the operator cover.
2-2. Attach the antenna to the Receiver. An extension
cable will be required if the operator cover is
metal. Ideally, antenna should be vertical and in
line-of-sight of the Transmitter(s).
2-3. Connect power (12-24 VAC/DC) to the terminals
marked POWER (not polarity sensitive).
Determine which monitored interface your
operator uses. Connect the COM and the
correct output connections (P/N.C., 10K) to your
operator. The Output Select dip switch 1 is
set to “R” for all operator’s requiring either a N.C.
or a 10K input, or set to “P” for operator’s that
require a pulsed input. Switch 2 has no function.
2-4. Apply power to the Receiver. Observe that the
green and yellow LEDs are on. The Channel 1
red LED will blink, and the Channel 2 LED will be
on solid. After 15 seconds, the Channel 2 LED will
go out, unless there is a Transmitter associated
with it. If the yellow LED is blinking randomly, at
least one Transmitter has been Learned and is
working.
