Troubleshooting
Fault: Blockage in the downstream progressive system
Cause: Correction:
Bearing, lines or metering device clogged
Â
Find out which is the cause of the blockage and rectify it in
accordance with he following example.
Â
Allow pump to run (see ”To trigger an additional lubrication
cycle”).
Â
Loosen all main line connections (pos. G) one after the
other from the main metering device (B, Fig. 29) leading to
the secondary metering devices. If f. ex. grease or oil
emerges under pressure from outlet 1 of main metering de-
vice (pos. B), the blockage will be found in the lubrication
circuit of the secondary metering device (pos. D).
In the case of the standard metering devices SSV D 6 to
SSV D 22 the outlet boreholes 1 or 2 are closed.
The fault can be identified by:
a) grease leaking at the pressure relief valve.
b) the fact that the indicator pins installed on the metering
devices (if any) no longer move.
c) the fault signal of the signal lamp (if any) or LED display

IMPORTANT
If there is a blockage in the downstream
system, the main lines are under pressure. In
such a case, it is difficult to detach the push-
in type connecting parts of the main line.
Relieve the system by removing the closure
plug on the push-in type pressure relief valve
valve or, if any, by removing the filling nipple.
Â
Let the pump run.
Â
Disconnect all lubricant feed lines E from secondary meter-
ing device D one after the other. If f. ex. grease or oil
emerges under pressure from outlet 3 of metering device D,
the blockage will be found in the line of outlet 3 or in the
connected bearing.
Â
Pump the blocked bearing or line through by means of a
manual pump.

NOTE
When checking the individual outlets, keep
each outlet loosened for quite a while be-
cause per each motor revolution there is only
one piston stroke. A complete cycle of all
metering devices requires several strokes.
