3-core screened cable between the GENIbus
terminals A, Y, B.
2. Set the needed analog and digital inputs
according to the connected equipment and the
required functionality. See section 13.42 Assisted
pump setup.
3. Assign pump number 1 to the first pump. See
section 13.25 "Number" (Pump number).
4. Assign pump number 2 to the other pump. See
section 13.25 "Number" (Pump number).
5. Select the Assist menu on one of the pumps and

6. Press [>] to continue.
7. Select Wired GENIbus as the communication
method to be used between the two pumps.
8. Press [>] twice to continue.
9. Select the desired multipump function. See
section 13.45.1 "Alternating operation" and
13.45.2 "Backup operation" above.
10. Press [>] to continue.
11. Press [OK] to search for other pumps.
12. Select the pump from the list.
13. Press [>] to continue.
14. Set the time for pump changeover i.e. the time at

13.46 Description of control mode
This menu is only available in the advanced control
panel.
This menu describes each of the possible control
modes. See also section 13.5 "Control mode".
13.47 Assisted fault advice
This menu gives guidance and corrective actions in
case of pump failures.
14. Bus signal
The pump supports serial communication via an
RS-485 input. The communication is carried out
according to the Grundfos GENIbus protocol and
enables connection to other pumps as well as a
building management system or another external
control system.
Via a bus signal, you can remote-set pump operating
parameters, such as setpoint and operating mode. At
the same time, the pump can, via the bus, provide
status information about important parameters, such
as actual value of control parameter, input power and
fault indications.
Contact Grundfos for further information.
This step applies only if you have selected
"Alternating operation, time" and if the
motors are fitted with FM 300.
If you use a bus signal, the number of
settings available via R100 or Grundfos
GO are reduced.
