5.2.3
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.
6. Enter the SIL locking code
7452
.
If the SIL locking code has been entered correctly, the message
"End of sequence"
appears on the display.
7. Press the key to confirm.
The SIL mode is now deactivated.
