2) The highest priority of the device is to record the density via the analog input, as long as the analog input is activated as a density input. If the analog input is not
available as a density input, the system attempts to record the density via the HART input. If both the analog input and the HART input are deactivated as a density
input, the system uses the default density value.
3) The connection via the analog input or HART input is described in the chapter titled "Electrical connections" on page 29.
5) The highest priority of the device is to record the temperature via the analog input, as long as the analog input is activated as a temperature input. If the analog input is
not available as a temperature input, the system attempts to record the temperature via the HART input. If both the analog input and the HART input are deactivated
as a temperature input, the system uses the default density value.
6) The highest priority of the device is to record the pressure via the analog input, as long as the analog input is activated as a pressure input. If the analog input is not
available as a pressure input, the system attempts to record the pressure via the HART input. If both the analog input and the HART input are deactivated as a
pressure input, the system uses the default pressure value.
8) The biogas proportion can be determined via the analog input, HART input or default setting. The highest priority of the device is to record the biogas proportion via
the analog input, as long as the analog input is activated as a biogas proportion input. If the analog input is not available as a biogas proportion input, the system
attempts to record the biogas proportion via the HART input. If both the analog input and the HART input are deactivated as a biogas proportion input, the system
uses the default biogas proportion value.
9) In order to implement the "Bio Std/Norm Vol." mode, as a precondition the required parameters from one of the NG2 modes must be available.
10) In order to implement the "Steam/Water Mass" mode with internal density determination, the selection "Calculated from..." must be set in the Device Setup /
Plant/Customized / Compensation Setting -> Density Selection menu.
11) In order to implement the "Steam/Water Mass" mode with external density determination, in the menu Device Setup / Plant/Customized / Compensation Setting ->
Density Selection the selection "Ext. Density" must be made.
