Logged Error Codes

This page displays a record of the last six system Errors Codes that have occurred in
order to assist in the diagnosis of any past anomalies. Errors Codes are only logged
at the end of every measurement cycle and indicate a change in status of single or
multiple errors. For example, if an Error Code 0004 was logged this would indicate
NO FLOW DURING RECOVERY PHASE
would indicate that the error had now cleared, i.e. the status had changed.
At fi rst switch on of the Condumax II nothing will appear in the ERROR CODE column.
When an error has occurred, but then cleared so that no outstanding errors exist, 0000
will then be logged continually.
Logged Error Codes and Error Indication (Modbus Register 35). See also Appendix F
'FORMAT C' for more details.
The 4 digit error codes are a hexadecimal number and are dependent upon the bits set
within the error indication register.
