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 fixed blanking function, the floating 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 fixed blanking function, the floating 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 floating 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.
