3-1-3 Auxiliary Output Switching Function
This function changes the operation state of the auxiliary output. It is useful when desired to make an
indicator to operate or inform the operation state of the SE4D series to PLC.
The following settings are selectable.

Notes: 1) When the xed blanking function, the oating blanking function or the muting function is used, the setting of ON / OFF
under unstable light-receiving condition does not work.
2) By the setting of ON / OFF in light receiving condition, light-receiving / light interrupted condition is output regardless of
the xed blanking function, the oating blanking function or the muting function.
<e.g.>
When the fixed blanking function is used, if an obstacle exists in the set area and other area is in light receiving
condition, the control output (OSSD 1 / 2) is in ON sate, however, the auxiliary output becomes OFF since the SE4D
series has been detecting the obstacle.
3) The state of the auxiliary output remains the same even if the SE4D series state changes.
If the oating blanking function is used, the incident light intensity indicator is turned OFF
when an obstacle exists in the sensing range regardless of the incident light intensity.
Do not use the auxiliary output for the purpose of stopping the machine in which the SE4D
series is installed. Failure to do so could result in death or serious injury.
