The submenu points described below.
Adjustment process
A parameter change with SIL qualified instruments must always be
carried out as follows.
•
Release adjustment
•
Change parameter
•
Lock adjustment and verify modified parameters
This ensures that all modified parameters were consciously changed.
Release adjustment
The instrument is shipped in locked condition.
As a protection against unintentional or unauthorized adjustment, the
instrument is locked against all parameter changes in normal operat-
ing condition.
For each parameter change you have to enter the PIN of the instru-
ment. In delivery status, the PIN is "0000".
If adjustment is enabled, the safety function must be considered
as unreliable. This applies until the parameterization is terminated
