Commissioning/Operation
The pressure switch may only be commissioned and operated by authorized staff.
CAUTION
Do not put the switch into operation when the switch itself or the connection cable is damaged.
WARNING
Be aware of the fact that in case of operation with higher temperatures the casing surface may
become very hot!
Apply high pressure first, followed by the low reference pressure.

After having been switched on the switch runs through a self-test. If the software recognizes an
error during the self-test or during operation, this is signaled in the display by "Err" and the
corresponding message, refer to Error list on page 7. The red LEDs S1 and S2 signal the activity
of the two switching points.
Operation is menu-driven via three keys:
CAUTION
Do not use any pointed, hard objects for making entries. The keys may be damaged by pointed,
hard objects.

IO-link version
General information
This device features an IO-link communication interface which requires an IO-link capable module
(IO-link master) for operation. The IO-link interface permits direct access to process and diagnostic
data and offers the possibility of parametrising the device during operation. Moreover
communication via a point-to-point connection using a USB adapter cable is possible.
Device-specific information
The IODDs required for the configuration of the IO-link device and detailed information about
process structure, diagnostic information and parameter addresses are available at ->IODD finder
and on https://www.barksdale.de/de/download/iolink/. To find the required information please enter
the order code in the search mask. IO-link devices manufactured before 04-01-2019 do not
support different polarities of the switching outputs.
NOTE: Since process connection, seal and measuring cell have no influence on the IO-link
communication you must replace them by "xx". E.g. BDS375VM0010BP = BDS37xxM0010Bx
TIP: Use the autocomplete function of the IODD finder by entering the article no. character by
character. If your device has been manufactured before 04-01-2019 please take into account that
the proposed device ID begins with 0x070.
