INDICATORS FOR APPLICATION ON SUCTION LINE
NORMALLY USED ON FS7 / FA1 series (suction line)
The clogging indicator registers the pressure downstream the filter element:
• in the VISUAL indicator the red area shows the need for element replacement.
• in the ELECTRIC indicator an electrical switch is activated.

LC24
The LC24 connector can replace the
standard black connector of the “S13” indicator (N.B. supplied separately).
Feeded with 24V, it gives a visual indication
of the filter element conditions: normally the
GREEN LED is on, the RED LED switch on
when the element is clogged.

INDICATORS FOR APPLICATION ON RETURN LINE
NORMALLY USED ON FA1 (return line) / FA2 / FR1 / FR6 / FCR7
The clogging indicator registers the pressure upstream the filter element:
• in the VISUAL indicator the red area shows the need for element replacement.
• in the ELECTRIC indicator an electrical switch is activated.

USER INFORMATION
The Pressure indicator measures the pressure in one point only:
-for suction application it must be located downstream the filter element (P-)
-for return application it must be located upstream the filter element (P+)
The Differential indicator measures the Dp between upstream and downstream of the filter element, i.e. it
is the ideal indicator for in line application.
The Pressure Drop (Dp = differential pressure) through the filter increases during
the system operation due to the contaminant retained by the filter element.
The filter element must be replaced when the indicator shows an alarm and before
the Dp reaches the by-pass set value (i.e. the set value A of the clogging indicator
must always be lower that the set value B of the by-pass valve).
WARNING: in cold start conditions a false alarm can be caused by higher oil viscosity due to low temperature; the indicator alarm must be considered at normal working temperature only.
OPTIONAL VERSIONS
Subject to MOQ our differential indicators can be supplied in special versions like ATEX, different
connectors, two alarm levels, etc.: pls contact our Customer Service for further information. ELEMENT ∆p
