Operation with the S-ND control unit

Optionally the micro annular gear pump mzr-2942 can be delivered with the
controller S-ND.
The controller S-ND controls the number of revolutions to achieve a constant
flow rate or positions the motor for precise dosage volumes. Values can be set
with the help of a potentiometer or with the external control signal 0-10 V.
Second a serial interface allows the control of precise feeding and dosing tasks
by an external PC. Included in the delivery volume are diskettes with a

dosing tasks by defining dosing data. A zero modem cable is included in the
delivery volume to connect the pump controller S-ND with a PC.
