Electrical monitoring (microprocessor control)

A piston detector (initiator), which has been installed on
a metering device instead of a piston closure plug
(M 11 x 1), monitors the pump operating time and brings
it to a close after all the pistons of this metering device
have dispensed their lubricant quantity.
If there is a blockage in the system or if the pump reser-
voir is empty, the piston detector can no longer record the
piston movements. The switching off signal is not trans-
mitted to the control unit. A fault signal occurs.
NOTE
For the system monitoring it is recom-
mended that one SSV-N metering device
with pre-assembled piston detector be
used per lubrication circuit. These special
6001a02
metering devices must be ordered sepa-
rately for each lubrication system. Refer to
the Parts Catalogue.
The pre-assembled metering devices have the designa-
tion SSV ... - N (they are available for SSV 6, 8, 10
and 12). They must be installed in the system instead of a
normal metering device.

Pressure relief valve
The whole system can be monitored visually via the pres-
sure relief valve. If lubricant is leaking at the pressure re-
lief valve during the distribution sequence, this indicates
that there is a blockage in the system.
IMPORTANT
In the case of the progressive metering
devices models SSV6 to 22 and SSV6-E
to 22-E outlets 1 and/or 2 must never be
closed, otherwise the system will block
6001a02
owing to the structure of the metering
device.
NOTE
Pressure relief valves to be ordered sepa-
rately (see parts catalogue).
