7.3 Errorconguration
InErrorconguration,congurethestatusesofvariouserrorcauses.
This allows the system to notify the user of the occurrence of an error according to the status
categoriesintheErrorconguration.
Select a status category from among Off, Warn. (Warning), and Fault.
“Fault”automaticallyperformsburn-out.WhenBurnhasbeensettoOff(7.2Outputsetup),only
the error message is displayed.
“Warn.” displays an error message.
When selecting PH201G in the communication setting, make sure that the “Fail contact” setting
is appropriate.
The settable causes of errors are determined based on the settings of the Sensor setup and
Measurement setup, and a status category is set to the causes displayed in the Errors 1/3 to 3/3
screens.
