14.4 Manual mode operation when
PROFIBUS is enabled
In Manual mode, if PROFIBUS is enabled, the P symbol will appear in the icon area.
The P will be white if there is data exchange, it will be red if there is no data
exchange. If there is no data exchange, the INFO button will become BUS STATUS
in red.
Press BUS STATUS to get the PROFIBUS STATUS screen, the background will
indicate pump status. It will not be red because this is not a critical error. The pump
is still operating but is not reporting diagnostics to the master.
The MODE button gives access to the PROFIBUS settings and the station address.
When the menus are accessed, the pump is technically still in MANUAL mode but with
no PROFIBUS communications. After five minutes of inactivity the pump will revert
back to the MANUAL home screen and discard any unsaved changes, if there are still
no communications then the red P icon will be displayed. For further information on
PROFIBUS communication errors see section 14.7 PROFIBUS comunication errors.
