16.11 Operability
Local display The local display is only available with the following device version:
Order code for "Display; Operation", option B : 4-line; via communication
Display element
• 4-line liquid crystal display with 16 characters per line.
• White background lighting; switches to red in event of device errors.
• Format for displaying measured variables and status variables can be individually
configured.
• Permitted ambient temperature for the display: –20 to +60 °C (–4 to +140 °F). The
readability of the display may be impaired at temperatures outside the temperature
range.
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.
Remote operation Via HART protocol
This communication interface is present in the following device version:
Order code for "Output", option B : 4-20 mA HART, pulse/frequency/switch output
