Advanced control panel and wired motor
connection
1. Connect the two motors with each other with a
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
10.39 ""Assisted pump setup"" (Assisted motor
setup).
3. Assign motor number 1 to the first motor. See
section 10.22 "Number" (""Pump number"").
4. Assign motor number 2 to the other motor. See
section 10.22 "Number" (""Pump number"").
5. Select the ""Assist"" menu on one of the motors
and ""Setup of multi-pump system"".
6. Press [>] to continue.
7. Select ""Wired GENIbus"" as the communication
method to be used between the two motors.
8. Press [>] twice to continue.
9. Select the desired multimotor function. See
sections 10.42.1 "Alternating operation" and
10.42.2 "Backup operation".
10. Press [>] to continue.
11. Press [OK] to search for other motors.
12. Select the additional motor from the list.
13. Press [>] to continue.
14. Set the time for motor changeover, i.e. the time at
which the alternation between the two motors is
to take place.
15. Press [>] to continue.
16. Press [OK] to confirm the setting. The multimotor
function icons appear in the bottom of the control

10.43 ""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 10.4 "Control mode".
10.44 ""Assisted fault advice""
This menu gives guidance and corrective actions in
case of motor failures.
11. Bus signal
The motor enables serial communication via an
RS-485 input. The communication is carried out
according to the Grundfos GENIbus protocol and
enables connection to a building management
system or another external control system.
Via a bus signal, you can remote-set operating
parameters, such as setpoint and operating mode. At
the same time, the motor can, via the bus, provide
status information about important parameters, such
as actual value of the 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.
