Switching output for OutA or OutB, analogue output
The switching outputs OutA and OutB and the analogue output are permanently
assigned to the distance input variable. Settings are made via the TeachIn, dis-
play and pushbuttons or via IO-Link (SOPA -...- PNLK -...).
Switching Output for OutC
The switching output OutC is permanently assigned to the supply pressure monit-
oring. The setting is made via the display and buttons or via IO-Link (SOPA -...-
PNLK -...). The binary signal at OutC acts as an enable signal for OutA and OutB.
If the supply pressure is outside the switching window of OutC, [SUP.P] appears in
the display. The sensor module is then unable to conduct a correct distance mon-
itoring procedure. It is not possible to teach the binary signals in this case.

Switching Functions
The binary signals OutA and OutB can be configured independently of one anoth-
er. The threshold value switching function is assigned to the binary signal OutA
and OutB ('distance' input variable). The window comparator switching function is
assigned to the binary signal OutC ('supply pressure' input variable).
–
The switching element function 'normally closed contact' (NC) or 'normally
open contact' (NO) can be assigned to each binary signal.
–
The switching point (SP) and hysteresis (HY) can be set for the binary signals
OutA and OutB. Only the switching points can be adjusted for OutC.

Hysteresis
Hysteresis serves to suppress switching signals in the event of fluctuations
around the switching point. The reset points function as long as the value is with-
in the hysteresis range.
–
Upper reset point = switching point + hysteresis
–
Lower reset point = switching point - hysteresis

are suppressed in the event of

NOTICE!
Damage due to Ingress of Foreign Matter or Liquids
In the event of an inappropriate measuring nozzle configuration or inappropriate
routing of the compressed air lines, foreign matter or liquids (e.g. condensation)
can enter the product and cause a malfunction or damage the product.
•
Prevent the entry of foreign matter and liquids through design measures,
for example through a suitable configuration of the measuring nozzles.
•
Place sensor module above the measuring nozzles
