Two Fieldbus connectors (IN and OUT) allow to setup arrays of multiple pumps. Therefore, serial pumping
configurations as shown in Figure 6 can be realized.

(Special firmware for serial pumping as one unit available on request.)
2.2.3 System Configuration for OEM Models
When using the pump system in speed control mode, the speed can precisely be set via an analog input.
Various digital inputs and outputs allow controlling and monitoring of the system. A RS485 enables
communication with a PC with the Levitronix
®
Service Software. Hence parameterization, firmware updates
and failure analysis are possible. The RS485 can also be used as a fieldbus to implement more intelligent
concepts of pump control.
