This function can be used for monitoring purpose by connecting with a device such as a PLC. 
The auxiliary output operation can be selected from the following seven operation modes by 
the F39-MC11 setting console. 
 

1.5.1.   Dark-ON output mode 

When a beam is interrupted, the auxiliary output goes to the ON-state. This state is inverted 
from that of the OSSD outputs.

1.5.2.   Light-ON output mode 

When all beams are in the light reception state, the auxiliary output goes to the ON-state. 
This state is the same as that of the OSSD outputs.
