Part 2 - Power Wire Connection
Note: The Receiver requires a constant nominal voltage of 24 V ac to operate. It
should only be connected to an irrigation controller that uses a 24 V ac approved
Class 2 transformer to supply power.
Caution: Do not connect the Receiver directly to 120/240 V ac power as
this may result in irreversible damage. If you are in doubt, contact a quali-
fied installer or electrician.
1. Disconnect power to the controller.
2. Follow applicable wiring procedure A or
B.
A. Controllers with
24 V ac terminals:
Refer to Figure 8 (page 5). Terminals for 24 V ac power are present on the
majority of controllers. Typical markings are “24 VAC”, “24 and 24”, “0 and 24”
and “Hot Post and 24.” Verify correct voltage, then simply attach the two Red
power wires to these terminals leaving existing connections in place.
B. Controllers with no
24 V ac terminals:
Refer to Figure 9. On controllers that do not have 24 V ac terminals, connect the
two Red power wires to the transformer’s secondary 24 V ac power wires where
they attach to the controller’s circuit board or use an optional 24 V ac transformer.
Note: This procedure will require a solder or wire-splice connection. If you are unsure
how to do this correctly, contact a qualified contractor or electrician for assistance.
Initial Signal Testing
Connect power to the controller and verify the Receiver’s Power Indicator is illumi-
nated. Hold the Sensor/Transmitter close to the Receiver, then press and hold the test
spindle. The Sensor Status Indicator should illuminate and remain on until the test
spindle is released. The Signal Indicator should also illuminate during the test to veri-
fy good signal strength. If either indicator does not illuminate, recheck your wiring.
Verify that both antennas are fully extended and straight.
