Further parameter settings
The following parameters affect the safety function. However, they may be freely configured in
accordance with the application:
It is recommended to note down the configured values!

The following parameters affect the safety function and are not freely configurable in Expert mode.
Instead, they are automatically set by the device to the safety-related values mentioned at the start
of SIL confirmation:

Setup → Advanced setup → Application → Tank calculation → HyTD → HyTD mode
Setup → Advanced setup → Application → Tank calculation → CTSh → CTSh mode
Setup → Advanced setup → Application → Alarm → Alarm X → Error value
Setup → Advanced setup → Application → Alarm → Alarm X → Alarm mode
Setup → Advanced setup → Safety settings → Output out of range
Diagnostics → Simulation → Simulation distance on
Diagnostics → Simulation → Current output 1 simulation
Expert → Input/output → Digital Xy-z → Error on event
Expert → Input/output → Analog I/O → Error on event
Expert → Input/output → Analog I/O → Output out of range
Expert → Input/output → Analog I/O → Feedback threshold
Those parameters which are not mentioned do not affect the safety function and can be
configured to any meaningful values. The visibility of the parameters mentioned in the
operating menu depends in part on the user role, the SW options ordered and on the
configuration of other parameters.
Unlocking a SIL device
When SIL locking is active on a device, the device is protected against unauthorized operation by
means of a locking code and, as an additional option, by means of a hardware write protection
switch. The device must be unlocked in order to change the configuration for proof-tests as per test
sequence A →  20, test sequence B →  22or test sequence C →  24.
