Setting the mode of operation
The desired mode of operation is selected with
a jumper (small electrical bridge) on the
electronic circuit board by simply putting it
on the corresponding pin couple. Default
setting of the device is mode of operation 1
(shown in the figure on the right side). If
another mode of operation is required, pull
jumper upwards with a forceps and put it onto
the pin couple that corresponds to the desired
mode of operation.

With mode of operation 1 the revolutions of the rotor of the pump can be adjusted to a
fixed value. Potentiometer P1 is used for gross speed adjustment, potentiometer P2 is
used for fine speed adjustment. The range selector switch SW is out of function.
