displayed, the SIL device is not locked. The safety-oriented parameter settings have been
made but the SIL device has not been locked.

Perform SIL device locking again.
5.5.4 Unlocking a SIL device
A device in the locked SIL mode is protected against unauthorized operation by means of a SIL
locking code and, where applicable, by means of a user-specific release code and a hardware
write protection switch. The device must be unlocked in order to change parameters, for
proof-tests as well as to reset self-holding diagnostic messages.
NOTICE
Unlocking the device deactivates diagnostic functions, and the device may not be able to
carry out its safety function in the unlocked SIL mode.
‣
Therefore, independent measures must be taken to ensure that there is no risk of danger
while the SIL device is unlocked.
Unlocking procedure:
1. Check the write protection switch (WP) in the connection compartment.
2. Set this switch to the OFF position where necessary.
 Hardware write protection disabled.
3. Enter the user-specific release code if necessary.
4. In the Setup menu → Advanced setup submenu, select the Deactivate SIL wizard.
5. Select Reset write protection parameter.
