If the device is locked and the parameter settings cannot be changed, it must first be
enabled via the hardware or software lock. The device is write-protected if the lock symbol
is shown on the display.
To unlock the device
• either switch the write protection switch on the electronics module to the "OFF" position
(hardware write protection), or
• deactivate the software write protection via the operating tool. See the description for
the 'Define device write protection' parameter. →  83
When hardware write protection is active (write protection switch set to the "ON"
position), write protection cannot be disabled via the operating tool. Hardware write
protection must always be disabled before software write protection can be enabled or
disabled via the operating tool.
