Manual Operation
4.5.8.3.
mA-OUT Menu
In the submenu mA-OUT the
4…20 mA outputs can be configured.
Each analog output can show one of the following three parameters:
FLOW:
The output current is proportional to the actual flow.
TEMP:
The output current is proportional to the actual temperature.
BATCH COUNT:
The output current is proportional to the actual batch value.
This mode is only possible, if the control input is configured as
“RESET BATCH”
The value for 4 mA as well as the value for 20 mA can be freely selected. Thus it is possible to zoom in (e.g.
temperatures from 20 °C to 30 °C) or to show negative values as well (e.g. flow from -10 kg/min to +20 kg/min).

UP DOWN EXIT
Use the keys
“UP” and “DOWN” to select the desired output channel and confirm with “P” or skip with “EXIT”.
The standard TCE electronics provides two analog
4…20 mA outputs, I1 and I2. If the option “Pressure
compensation” is installed, only the output I2 is available.
The display shows

UP DOWN EXIT
Use the keys
“UP” and “DOWN” to select the desired output value and confirm with “P” or skip with “EXIT”.
The display shows

G/S
RIGHT UP EXIT
The indicated engineering unit depends on the selected output value and the display setup.
To input a negative sign (e.g. for
“-20 °C”), move the cursor to the first digit. When the figures are incremented
by pushing
“UP” the “9” is followed by the minus sign “-“, before the “0” appears.
Use the keys
“RIGHT” and “UP” to select the desired value for 4 mA and confirm with “P” or skip with “EXIT”.
The display shows
VALUE AT 20mA
5.00000
G/S
RIGHT UP EXIT
Use the keys
“RIGHT” and “UP” to select the desired value for 20 mA and confirm with “P” or skip with “EXIT”.
The display returns to the SETUP IN/OUTPUTS menu.
