3.3 Applications
The application alternatives for the product are the following:
3.3.1 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.
3.3.2 Controller (constant pressure)
This mode is set as the default operating mode and is used for a unit in a single pump operation.
3.3.3 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 can take control.
