Bus Communication Via Genibus - Grundfos GENI Montage- Und Betriebsanleitung

Checking the function
One pump must be operating and the other must be stopped.
• Start the pump that was stopped.
• Check that the operating pump stops.
Note: The check can be made, whether standby or alternating operation has
been selected.

9. Bus communication via GENIbus

The GENI module enables serial communication via an RS-485 input. The
communication is carried out according to the Grundfos bus protocol, GENI-
bus, and enables connection to the GRUNDFOS Pump Management System
2000, a building management system or another type of external control sys-
tem.
Via the bus signal, it is possible to set pump operating parameters, such as
desired setpoint, temperature influence, operating mode, etc.
At the same time, the pump can provide status information about important
parameters, such as actual head, actual flow, power input, fault indications,
etc.
For further details, consult the operating instructions for the GRUNDFOS
Pump Management System 2000 or contact Grundfos.
Note: When the pump is controlled via a bus signal, the number of settings
available on the pump control panel or with the R100 will be reduced.
