Warning!
Checks:
Write protection must be checked as follows:
1. TTH300-.H, TTF300-.H, and TTF350-.H locking via the LCD display with local keyboard
- Check whether the lock icon is displayed on the LCD display.
- Select the "Fault Signaling" menu and make sure the edit icon is not showing on the
LCD display.
- Press the Edit button and check that there is no response on the LCD display.
2. TTH200-.H, TTR200-.H, TTH300-.H, TTF300-.H, and TTF350-.H protection via DTM/EDD:
- LCD display and local keyboard available: Check as described under Point 1.
- No LCD display and local keyboard available (checking write protection):
Go to <Device>,<Parameterize> Current Output / Damping and change the damping
value, for example. Then select "Save Device Data in Device" and check whether the
message "Device is write-protected" is displayed.
Warning!
The software write protection does not lock again automatically. It remains unlocked until it is
specifically reset.
