correctly
Faults displayed during operation
Overload (above measuring range of the sensor).
Underload (below measuring range of the sensor).
Flashing: short circuit in the switching output 1*.
Flashing: short circuit in the switching output 2*.
Flashing: short circuit in both switching outputs*.
*The output concerned is switched off as long as the short circuit exists.
Cleaning of the filter cover
If viscous and residues producing
media clog the filter cover of the
sensor (and thus reduce the mea-
suring accuracy slightly), you can
clean it.
• Unscrew the filter cover (B)
(use a pair of pliers with plas-
tic-covered jaws for this).
Clean the cover thoroughly.
• The vent (A) should only be
cleaned by skilled personnel
and with utmost care.
Possible medium residues must not be compressed and pressed
into the vent. This could clog the filter system and reduce the
measuring accuracy of the sensor.
• Screw the filter cover again tightly.
The sensor is sufficiently protected against harsh ambient conditions
(protection IP 67). The protection rating can be increased by a special
accessory (order no. E30043).
