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.

Note: Specific firmware for serial pumping as one unit available on request.
2.2.3 System Configurations for OEM Models
The OEM model, with one integrated cable only, is design for compact integration into an equipment. 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.
