Siemens 7SJ82, Manual

Page: 505 / 1638

With the
Threshold light
parameter, you set the light sensitivity. If you set
Threshold light
to a
smaller value, the sensitivity increases. If you set
Threshold light
to a higher value, the sensitivity
decreases. If the sensors even pick up in case of a switching arc of the circuit breaker, set the
Threshold
light
parameter to a higher value.
Siemens recommends the default settings for point or line sensors.
Set the parameter
Threshold light
manually only if you have special default settings for light sensitivity.

channels.
