Description


GENIbus/M-Bus device is protocol converter which enables remote monitoring of up to three Grundfos circulation pumps over M-Bus port of Danfoss ECL APEX 10 heating substation controller. It has LED indications of power, receive and transmit of GENIbus and M-Bus communications. GENIbus line termination can be enabled with DIP switches. M-Bus address is adjustable with three BCD rotary switches. All ports are mutually galvanic isolated. Power supply is from 8V to 32V DC. Device is designed for mounting on industrial DIN 35 rail.

 

Application



GENIbus/M-Bus device is completely adjusted and designed for remote monitoring of Grundfos circulation pumps in heating substations.

It enables remote monitoring of following pump parameters:

  • Pump speed [rpm]
  • Pump status [ON/OFF]
  • Pump status error [alarm code]
  • Pump flow - calculated [m3/h]
  • Pump head – differential pressure [kPa]
  • Pump power [W]
  • Pump working hours [h]
