ABB FSM4000 - Diagnostic Warning and Error Messages; Error Registers for Diagnostic Values; Error Registers for Wiring Errors

FSM4000 ELECTROMAGNETIC FLOWMETER | OI/FSM4000-EN REV. E 105
Diagnostic warning and error messages
All values acquired during diagnostics or a wiring error can trigger warnings or error messages.
Warnings are displayed in the 4th display line only. In case of an error, in addition to the signal in the 4th display line, the switch
output (‘General alarm’ setting or ‘ext. Diag. Alarm’ is set to the alarm condition.
To activate this option, select in the submenu ‘Diagnosis / Alarm Settings’ whether the error or warning is triggered in the event of
up-scale or down-scale of the specified range. To check for wiring errors, you can activate this function in the ‘Diagnostics / Wiring
Error’ submenu.
For additional information, refer to the relevant error registers. These can be selected or called up in the ‘Display’ or ‘Status’ submenu
The error registers for diagnostic values are structured as follows:
ID code

B
−
Electrode balance
m
−
Electrode voltage E1
E

HMx
Hist Max Errors
Error / Warning: Limit value up-scale (max.) while transmitter is powered-up.
HMi
Hist Min Errors
Error
/ Warning: Limit value down-scale (min.) while transmitter is powered-up.
EMx
Curr Max Errors
Error: Number of current limit value up-scales (max.).
EMi
Curr Min Errors
Error:
Number of current limit value down-scales (min.).
WMx
Curr Max Warn
Warning: Number of current limit value up-scales (max.).
WMi
Curr Min Warn
Warning:
Number of current limit value down-scales (min.).
The display EMx _R______B__ indicates for example a max. alarm in the current values for the coil resistance and electrode balance.
The error registers for wiring errors are structured as follows:
ID code Set Off Designation
M − Coil short-circuit to ground
E − Wiring error for electrodes
