Troubleshooting<strong>Proline</strong> <strong>Promass</strong> 83 <strong>Modbus</strong> <strong>RS485</strong>"Caution!!Note!9.2 System error messagesSerious system errors are always recognized by the instrument as "Fault message" and are shownas a lightning flash ($) on the display! Fault messages immediately affect the outputs.In the event of a serious fault, a flowmeter might have to be returned to the manufacturer for repair.Important procedures must be carried out before you return a flowmeter to ä 107.Always enclose a duly completed "Declaration of contamination" form. You will find a preprintedblank of this form at the back of this manual.äSee the information ä 41.<strong>Modbus</strong> No. Device status message(local display)Cause Remedy (spare part ä 101)Register:6859Data type:IntegerRegister:6821Data type:String (18 byte)Response to a fault message:The value "NaN" (not a number)is transmitted to the <strong>Modbus</strong>master instead of the currentmeasured value.Depicted on the local display:S = System error$ = Fault message (with an effect on the outputs)! = Notice message (without any effect on the outputs)1 SYSTEM OK – There is no error present in the deviceNo. # 0xx Hardware error2 CRITICAL FAIL. 001 S: CRITICAL FAILURE$: # 0013 AMP HW-EEPROM011 S: AMP HW-EEPROM$: # 0114 AMP SW-EEPROM 012 S: AMP SW-EEPROM$: # 012Serious device error.Amplifier: faulty EEPROM.Amplifier:Error accessing EEPROM data.Replace amplifier board.Replace amplifier board.The EEPROM data blocks in which an error hasoccurred are displayed in theTROUBLESHOOTING function.Press Enter to acknowledge the errors inquestion; default values are automaticallyinserted instead of the faulty parameter values.!
