g) Outputs 4…20mA in dosage mode [2531]
Example with creation of a 4…20mA output in dosage mode.
Press to open following screen.
 AO2 Function Dosing
- Output 4…20mA operation mode selection, on this selection button we find the information of the
output being modified (
AO2) and the function currently selected (Dosing).
Press to change it.
 Assignment pH E01
- Selection of the parameter to which this output 4…20mA is attached, on this selection button we find
the configuration type information (
pH) and its « code » (E01).
Press to change it.
 Output range 4…20mA
- Selection of the current range generated in dosing mode; on this selection button you find the
selected range information (
4…20mA).
Press to change it.
 Dosage direction Rising
- Choice of dosage direction, on this selection button we find the information of the selected dosage
direction (
RISING).
Press to toggle the mode from RISING to FALLING and change the dosage direction
 Dosing range
- See relay configuration in PWM dosage mode
 “Special” current
- This option isn’t necessarily present, it’s activated in the “OPTIONS” of the installer menu.
 Fault Low range
- Selection of the current that will be applied on the output in case of fault encountered, on this
selection button we find the selected current information (
Low range).
Press to change it.
Low range = 4mA if range 4…20mA selected; 0mA if range 0…20mA selected.
0mA = 0mA
2,6mA = 2,6mA
