Rain Bird ESP-8LX+ - Sensor System and Bypass Switch Configuration

31ESP-LX+ & LXi+ Installation, Programming, & Operation Guide
NOTE: For this feature to operate properly, the sensor
must be connected according to the instructions on
page 54.
➊ To activate the sensor system, set the sensor bypass
switch to ACTIVE. The controller will operate normally
until a wet condition is detected by the sensor.
NOTE: If no sensor is attached to the controller, make
sure the supplied jumper connects the two SENSOR
terminals on the controllers circuit board. If you set
the sensor bypass switch to ACTIVE without a
sensor or jumper connected to these terminals, the
valves will not operate, and no watering will occur. See
page 54 for instructions.
➋ When the sensor detects a wet condition, power to the
valves will be interrupted, and no watering will occur
(including manual program or station operation.) The
WATERING SUSPENDED BY SENSOR indicator will light
up.
Set Sensor System and Bypass
Switch
ESP-LX+ and -LXi+ controllers let you connect a sensor
system that interrupts watering when a wet condition is
detected. For example, if you have a Rain Bird Rain Check
sensor connected to the controller, irrigation will be prevented
when rainfall reaches the shutoff level in the sensors collector
cup.
