4.2 Remove Display / Activate Write Protection

Using the DIP switch in the device, you can disable changes to the configuration via the
display or via HART (not for type series CI4xx3 with a process connection on the back).

To activate the write protection, you must first remove the display module. Proceed as fol-
lows:



Unscrew the front cover



Turn the display module 20° counterclockwise



Lift off the display module carefully

Figure 5: Removing the display

After removing the display module you can reach the DIP switch on the CPU module. The
write protection is active when the DIP switch is in the "ON" position.

Figure 6: Write protection via slide switch in the device

Re-mount the display module in the reverse order.

4.3 Maintenance / Service

When properly installed in accordance with applicable specifications, this device is
maintenance-free. However, we recommend an annual recalibration of the device.

In case of damage or defects, the customer can replace the following elements:



Display module



Cable glands (if applicable)

For defects to other components, repairs must be performed in the factory.
