Write protection via write protection switch

Unlike parameter write protection via a user-specific access code, this allows write access
to the entire operating menu - except for the "Contrast display" parameter - to be locked.
The parameter values are now read only and cannot be edited any more (exception
"Contrast display" parameter):
• Via local display
• Via service interface (CDI)
• Via HART protocol
1. Loosen the securing clamp.
2. Unscrew the housing cover.
3. Pull out the display module with a gentle rotation movement. To make it easier to
access the lock switch, attach the display module to the edge of the electronics
compartment.
 Display module is attached to the edge of the electronics compartment.
