Sequentially block and unblock the sensor
and observe the Control Panel for a change
in state (0 to 1, or 1 to 0).
There is a change in state when the sensor
is blocked and unblocked.

Go to step 2.
The sensor and related circuits are working
correctly.
2. Using the following table, on the Punch
I/O PWB check the LED that corresponds
with the sensor. Sequentially block and
