Clogging indicator
NOTICE
Unsuitable/incorrect filter element
The medium is not filtered
►
Use only filter elements with the type code suffix –KB (for example:
1300 R 003 BN4HC /
-KB
)
Depending on the version, the unit has an optical dynamic pressure indicator
(2) (red/green) or a scale in the filter cover. The version with switchover may
have an optional differential pressure indicator (1).
Change the filter element as soon as the dynamic pressure indicator or
differential pressure indicator is in the red area.
The clogging indicator may respond briefly when there is a cold start, if a
higher back pressure arises due to low temperatures and the resulting high
viscosity. With electrical displays, a suitable time relay should be provided in
the local controller in order to suppress unnecessary malfunction messages.
