muting function.

Waiting mode
In the waiting mode the single beam safety light barrier is free (green LED).
Activation is not used. The safety outputs are open. This state is displayed by the red LED.
The waiting state is displayed through state "11" on the 7-segment display.
Protection mode
In protection mode, the function of the single beam safety light barrier is cyclically tested
every two seconds. The free protective field is displayed by the green LED.
Activation is used (green LED). The safety output is closed which is displayed by a green
LED.
