3. Overview, functional description
3.3 Function monitoring options
The described metering devices offer the
following function monitoring respectively
controlling options. Which of the specified
function monitoring options are possible for
the respective metering device models can
be found in the Technical data.
3.3.1 Visual monitoring with indicator
pin
The metering devices can be equipped with
an indicator pin for visual monitoring of the
metering piston’s movement.
3.3.2 Electrical monitoring/controlling via
proximity switch
The proximity switch detects the movement
of the indicator pin. Proximity switches are
used in combination with lubrication pumps
with control PCB or in combination with an
external control unit to monitor and, if nec-
essary, terminate the lubrication time.
3.3.3 Electrical monitoring/controlling
via piston detector
The piston detector detects the movement
of the metering piston. Piston detectors are
used in combination with lubrication pumps
with control PCB or in combination with an
external control unit to monitor and, if nec-
essary, terminate the lubrication time.
3.3.4 System-related monitoring
The individual components of a progres-
sive lubrication system equipped with SSV
metering devices are functionally connected
to each other. This means, in case of a block-
ade in the progressive lubrication system,
the pistons of the metering devices cannot
move any more. As soon as a piston blocks,
pressure in the progressive lubrication sys-
tem will rise until lubricant will leak from
the pressure control valve of the lubrication
pump or in case of progressive lubrication
systems with pressure control the lubrication
pump will be switched off.
