9.4 Digital Switching Output (Alarm)
With the help of a user-selectable distance threshold, the switching output
can be set to monitor objects or conditions for positive or negative overstep.
Figure 18 : Wiring diagram of digital switching output
For example, using the digital switching output, an object which was selected
for measurement can be monitored for excision of a threshold value. To do
this, parameter settings for a measurement window are required. Settings for
this window can be made via the three parameters: Alarm Center (AC), Alarm
Hysteresis (AH) and Alarm Width. The range which will be subject to
monitoring begins at AC and ends at AC+AW. Switching transitions can be set
via parameter AH.
