Fig. 40: KSB local bus wiring for master/auxiliary master/slave mode (1 main pump, 1
auxiliary pump, 1 slave pump)
1. The KSB local bus in the first and last PumpDrive must be terminated via a
resistor. This is implemented by means of a wire jumper between terminals 1
and 2 on terminal strip P4. If a graphical control panel is used on the first or last
PumpDrive, the wire jumper is not required.
2. At the centre PumpDrives, the DIP switches on the rear must, if a graphical
control panel is used, be set to OFF to deactivate the terminating resistor of the
KSB local bus.
