the sensor cover away from the mounting base
at the bottom, and rotate upwards until the
housing is separated from the base.
3. Disconnect sensor wiring by doing the following:
a. If the sensor is connected with an RJ-11
cable, carefully remove RJ-11 plug from the
back of the sensor.
b. If the sensor wiring is connected to a
terminal block, note the terminal locations
of each wire. It is advisable to take a
picture of the wiring for reference during the
re-assembly process. Then, carefully
remove the wires from the sensor terminal
block(s).
