The image on the left shows the input and output
LED indicators, use these with the chart below
To identify any faults with the barrier. The example
On the left shows that the barrier is lowered, the
Photocells/loop are healthy and the stop circuit is
Also healthy.
Note, the PLC is located in the barrier cabinet.
