Additional information For local operation, the customer-specific access code, which has been defined in the
Expert → System → Define access code sequence, has to be entered.
If an incorrect access code is entered, the user retains his current access authorization.
The write protection affects all parameters marked with the -symbol in the document.
On the local display, the -symbol in front of a parameter indicates that the parameter is
write-protected.
If no key is pressed for 10 minutes, or the user goes from the navigation and editing mode
back to the measured value display mode, the device automatically locks the write-
protected parameters after another 60 s.
Please contact your Endress+Hauser Sales Center if you lose your access code.
