3.2.1 Application alternatives
Actuator (constant speed)
The unit operates as an actuator according to speed set point; this is done through user
interface, the corresponding analog input or the communication bus.
Controller (constant pressure)
This mode is set as the default operating mode, and is used for single pump operating
units.
Cascade serial / Cascade synchronous
The units are connected via the RS485 interface and communicate via the provided
protocol. The combination of the different units which are used in a multi-pump system
depends on the system requirements.
It is possible to run all pumps in cascade serial mode and cascade synchronous mode as
well. If one unit fails, then each pump of the system can become the lead pump and take
control.
