15. 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, it is possible to remote-set motor 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 control parameter,
input power and fault indications.
Contact Grundfos for further information.
16. Priority of settings
The motor can always be set to operation at max. speed or to
stop with the Grundfos GO Remote.
If two or more functions are enabled at the same time, the motor
will operate according to the function with the highest priority.
Example: If, via the digital input, the motor has been set to max.
speed, the motor control panel or the Grundfos GO Remote can
only set the motor to "Manual" or "Stop".
The priority of the settings appears from the table below:
* If the bus communication is interrupted, the motor will resume its previous operating mode, for example "Stop", selected on the motor
control panel or with the Grundfos GO Remote.
Note
Note
If a bus signal is used, the number of settings
available via the Grundfos GO Remote will be
reduced.
