3.11.2.2 Connecting the Water Sensor
Context
A water sensor monitors resistance changes at terminals to determine whether the floor is
watery. When the terminals of a water sensor detect water or other conductive liquid,
resistance between the two terminals decreases. Keep water sensors far away from water traps
or floor drains.
Procedure
Step 1 Connect one end of the water sensor cable to the water sensor.
Step 2 Connect the other end of the water sensor cable to 7 and 8 on signal terminal X301 through
the signal cable hole at the bottom of the cabinet.
Step 3 Secure the cable to the right post of the cabinet using cable ties.
