Disconnecting the local display from the main electronics module
In the case of the "Compact, aluminum coated" housing version, the local display must
only be disconnected manually from the main electronics module. In the case of the
"Compact, hygienic, stainless" and "Ultra-compact, hygienic, stainless" housing
versions, the local display is integrated in the housing cover and is disconnected from
the main electronics module when the housing cover is opened.
"Compact, aluminum coated" housing version
The local display is plugged onto the main electronics module. The electronic connection
between the local display and main electronics module is established via a connecting
cable.
For some work performed on the measuring device (e.g. electrical connection), it is
advisable to disconnect the local display from the main electronics module:
1. Press in the side latches of the local display.
2. Remove the local display from the main electronics module. Pay attention to the
length of the connecting cable when doing so.
Once the work is completed, plug the local display back on.
Via PROFINET network
This communication interface is available in device versions with PROFINET.
