The pulse input makes it possible to control the delivery capacity by
means of pulses. The system regulates the delivery capacity by means of
the dosing pump's stroke frequency and number of strokes in depend-
ence on the number of pulses and the pulse spacing.

Remove the conductive rubber band before inserting the cable in the
connection socket.
After the cable has been removed, the conductive rubber band must be
reinserted in the connection socket. Insert it between pins 1+2 and 3+4
as shown in Fig. 19.
