Tab. 9 (part 3): Connection plan motor electronics
The flow rate can be varied by an external actuation (Sub-D-plug,
see Tab. 9).
The speed of the pump is controlled by a control voltage.
Please contact our KNF customer service for further information.
Remote ON/OFF is through an 9-pin controller connection (Pin 8,
see Tab. 9).
To start the motor, Pin 5 must be bridged to the ground of the
controller connection.
Please contact our KNF customer service for further information.
Switching off the pump
The life of the diaphragm is prolonged the formation of condensate
is avoided. Therefore the following precautions should be taken:

Run the pump for a few minutes to warm it up before handling
saturated or nearly saturated vapors.

KNF recommends: When transferring aggressive media, flush
the pump prior to switch off (see Chapter 8.2.1) to increase the
service life of the diaphragm.

Switch off pump with power switch (Fig. 1 at Chapter 5).

Restore the system to normal atmospheric pressure (release
pneumatic pressure in pump).

Pull out the pump’s main plug.
