Switching Outputs, Limit Value Monitoring
The switching outputs can be used independently of one another to monitor
-
the analog output,
-
limit values.
Switching output 1
Switching output 2
Switching output 3
Switching mode
Teach / Limit /
None
Teach: Target is outside the scaled analog range
Limit: Distance greater/less than the limit value
None: Switching output not active
Output level
NPN / PNP /
Push-pull /
Push-pull negated
NPN: Active during limit value monitoring, load
against supply
PNP: Active during limit value monitoring, load
against supply ground
Push-pull: Switching output is high when limit value
is exceeded
Push-pull negated: Switching output is low when
limit value is exceeded
Range check
Lower / Upper /
Both
Lower: Check if measured value below limit
Upper: Check if measured value above limit
Both: Check if measured value above or below limit
Upper limit in mm
Value
Sets the upper limit value for the switching output.
Lower limit in mm
Value
Sets the lower limit value for the switching output.
Hysteresis in mm
Value
Value by which the measured value must be above
or below the limit in order for the switching output to
be triggered or deactivated again.
Hold signal level in ms
Value
Specification of the minimum time for which the
switching output should remain active. The time
begins with the activation of the switching output.
