Operation access authorisation
To protect the transmitter against an unintended or undesired change in the
configuration and calibration data, functions can be protected using four-digit access
codes. Access authorisation has the following levels:
Display level (accessible without a code):
The complete menu can be viewed. The configuration cannot be altered. No calibration
is possible. On this level, only the controller parameters for new processes can be chan-
ged in the "DIAG" menu branch.
Maintenance code
Maintenance level (can be protected by the maintenance code):
This code allows access to the calibration menu.
Use this code to operate the temperature compensation item. The test functions and the
internal data can be viewed.
Factory setting Code = 0000, i.e. the levels are not protected.
You can ask for a universally valid maintenance code by contacting your service centre.
Specialist code
Specialist level (can be protected by the specialist code):
All menus can be accessed and changed.
Factory setting: Code = 0000, i.e. the levels are not protected.
You can ask for a universally valid specialist code by contacting your service centre.
To activate the codes (= functions locked) see the item "PARAM"
➞
"Set up 1"
➞
"Access
codes" (s. page 34).
Enter your desired code here. If the code is activated, you can only
edit the protected areas with the rights mentioned above.
!
Note!
•
Note down the selected code as well as the universal code and keep it in a place
where unauthorised persons do not have access to it.
•
If you set the code back to "0000", all the levels are freely accessible for editing.
The code can only be reset via the "specialist" menu.
