74 ESP-LX Modular Controller
Connect Sensor Wiring
The ESP-LX Modular controller lets you connect various types of
sensors that interrupt watering when a specific condition is
detected. For example, if you have a Rain Bird RSD Series Rain
Sensor or a WRS Wireless Rain Sensor connected to the controller,
watering will be suspended when rainfall activates the sensor.
The sensor must be connected to the controller’s sensor inputs
on the base module according to the instructions that come
with the sensor equipment.
Most sensors have two wires or two terminals designed to be
connected to the valve common wire. Instead of connecting to
the valve common wire, connect these wires or terminals to the
“SENSOR” terminals on the ESP-LX Modular controller.
NOTE: If no sensor is attached to the controller,
make sure the supplied jumper connects the two
SENSOR terminals on the controller’s base module.
If you set the sensor bypass switch to “ACTIVE”
without a sensor or jumper connected to these
terminals, valves will not operate, and no watering
will occur.
