Rain Sensor Installation (Purchased Separately)
IMPORTANT! The INHIBIT SENSOR is designed for a
normally closed rain sensor. The wire jumper must be present at the
terminals if a sensor is not connected.
Step 1 – Route the rain sensor cable into the controller terminals.
Step 2 – Remove the wire jumper from the INHIBIT SENSOR
terminals (INHI+ and INHI- for the 18 stations or
more models and INHIBIT+ and SENSOR- for the 12
stations or less models). Refer to the provided rain sensor
installation guide for wiring instructions and connect
accordingly.
The INHIBIT SENSOR will operate on any
Function Dial position settings.
Start Sensor Installation (Purchased Separately)
IMPORTANT! The START SENSOR input is designed for a
normally open sensor and works in conjunction with Option 10. When
the start sensor is activated, the MC-E controller will immediately
activate Program 1 providing Option 10 is activated. Program 1 will
continue to repeat the cycle until the start sensor is deactivated. The
activation of the start sensor will not affect any other programs.
Step 1 – Route the sensor connection cable through the bottom of
the controller cabinet and into the controller terminals.
Step 2 – Refer to the provided sensor installation guide for wiring
instructions.
The START SENSOR will operate on any
Function Dial position except for RAIN OFF.
