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 and SENSOR
terminals for the 18 stations or more models and
INHIB.SEN and SEN.COM 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 Options 9
and 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. Option 9 works similarly by turning ON program 8,
however all other programs are turned OFF.
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.
