►
Press [Set] briefly�
> The unit displays the corresponding parameter value for about 15 s� After
another 15 s the unit returns to the Run mode�
10.2 Fault indication
[OL]
Overload pressure (measuring range exceeded)�
[UL]
Underpressure range (measuring range below the minimum value)�
[Err]
Internal fault, invalid input (indicated even if the display is deactivated)�
10.3 Cleaning of the filter cover
If viscous and residues producing
media clog the filter cover of
the sensor (and thus reduce the
measuring accuracy slightly), you can
clean it�
►
Unscrew the filter cover (B) (use a
pair of pliers with plastic-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�
