Operation with the S-BL control unit (optional)

The micro annular gear pumps mzr-2542 and mzr-2942 with brushless DC
motor as drive be delivered with the S-BL control unit. This programmable
control unit enables to adjust speed for constant flow rates or the position of
the motor for the dosage of constant amounts of liquid. On the delivered
diskettes or CDs you will find a PC-program operating under Windows that
enables to program such parameters as speed, acceleration and current
consumption. The delivery package comprises also a null-modem cable for
connection to a serial interface of a PC.
