Title: 32 Pumper modbuss teknisk data.pdf.pdf
Check that the individual conductors have been fitted correctly.Check the power supply to the E-pump.Contact the nearest Grundfos company.Check the transmission speed, switches SW4 and SW5. If the switches are set to "software-defined", an invalid value may have been set via Modbus. Try one of the preselected transmission speeds, for example 19200 bit/ s.Check that the Modbus address, switches SW6 and SW7 has a valid value [1-247].Check that the Modbus address, switches SW6 and SW7 has a valid value [1-247].Check the transmission speed, switches SW4 and SW5. See section 5.1 Setting the Modbus transmission speed.Check the parity setting, switch SW3. See section 5.2 Setting the stop bits and the parity bit.Check the parity setting, switch SW3. See section 5.2 Setting the stop bits and the parity bit.Check the cable connection between CIM 200 and the Modbus network.Check the cable connection between CIM 200 and the Modbus network.
