• Section A shows information regarding the compressor operation (e.g. the outlet pressure or the
temperature at the compressor outlet). On compressors with a frequency converter, the load degree
(flow) is given in % of the maximum flow.
• Section B shows Status icons. Following icon types are shown in this field:
• Fixed icons
These icons are always shown in the main screen and cannot be selected by the cursor (e.g.
Compressor stopped or running, Compressor status (running, running unloaded or motor
stopped).
• Optional icons
These icons are only shown if their corresponding function is activated (e.g. week timer,
automatic restart after voltage failure , etc.)
• Pop up icons
These icons pop up if an abnormal condition occurs (warnings, shutdowns, service,...)
To call up more information about the icons shown, select the icon concerned using the scroll keys
and press the enter key.
