3.12.5 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 Water– and Water+ on the
water sensor at the signal port through the signal cable hole at the top of the
cabinet.
Step 3 Secure the cable to the left post of the cabinet using cable ties.
Place the sheet metal of the water sensor upwards and its detection board
downwards on the ground.
