9. BUS signal

The pump provides serial communication via an RS-485
interface. Communication is according to the GENIbus
protocol, and permits connection to a GLT or similar
system. (Possible types of control on request)
With the BUS signal it is possible to set pump operating
parameters such as reference value, mode of operation,
etc. from a remote point. At the same time the pump can
supply status information via the BUS for important
parameters, such as actual value of control parameter,
power consumption, fault indications, etc.
