Configuration

The device has been configured and tested according to customer order.
However, it can be configured via the LCD indicator with a local keyboard or via DTM / EDD
through the HART interface. Other configuration tools such as mobile handheld terminals are
not described in these instructions.
Reliable operation of the device is not assured during configuration.
Warning!
Checks:
Before commissioning the device, check whether the device setup assures the system's safety
function.
Make sure that the correct device has been installed at the correct measuring point.
Whenever the device is updated (if the device's mounting position is changed or the setup is
modified, for example), the safety function of the device must be checked again.
Once the safety function has been checked, the device must be write-protected to prevent
changes to the setup, since any change to the measurement system or parameters will impair
the safety function.
To ensure safe operation, the device must be write-protected.
To implement this, proceed as follows:
Activating / Deactivating write protection
1. TTH300-.H, TTF300-.H, and TTF350-.H via the LCD display with local keyboard
Go to "Device Setup", "Write Protection" and enter a password other than "0110" to activate
write protection. Enter the password "0110" to disable write protection (see the operating
instructions).
2. TTH200-.H, TTR200-.H, TTH300-.H, TTF300-.H, and TTF350-.H via DTM / EDD
Go to "Device" and select "Write Protection" to activate the function.
If the device is locked (write-protected), it cannot be configured. Write protection is applied
for the entire device. Enter the password "0110" to disable write protection.
3. TTR200-.H, TTH300-.H, TTF300-.H, and TTF350-.H, HW write protection via DIP switches
