15.1.7 Malfunctions on pump unit
in progressive system
Block operation
Block operation is the reaction of the control
unit to the absence of signals from the piston
detector.
Possible causes:

Defective lubrication lines

Blocked progressive feeder

Defective piston detector

Insuficient lubricant
No signal from piston detector
during pump cycle:

Normal operation is interrupted.

Block pause begins with query to
piston detector.
No signal from piston detector
during block pause:

Second lubrication cycle begins in
block operation.
As soon as a signal is received from the piston
detector, block operation is aborted and the
normal lubrication cycle starts with a pause.
A total of three lubrication cycles are
performed with query to the piston
detector.
No signal from the piston detector

Three pump cycles and two block pauses with-
out signal from the piston detector:
Block operation is aborted
Malfunction notiication is issued.
Fault notification on device display
Duration of block pause
