In this operation mode it is possible to start the pump for a defined number of
strokes or for a defined time. The start signal can be set manually, externally or by
means of a timer. The stroke frequency can be set manually in all these operation
modes.

Examples 3 and 4 can be combined in two pumps when both are driven with the same
mA signal in order to start the second pump as a complementary flow.
