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.
