17.8 Menu "Output 4-20 mA" → "Output channel 2"
Assign
Description Use this function to assign a process variable for current output 2.
Options • Off
• Density
• Ref. density
• Concentration
• Temperature
• Pressure
Factory setting Temperature
Additional information The "Concentration" option is only available if the "Concentration
Measurement" application package is used.
Span
Description Use this function to select the current range for current output 2.
Options • Namur 4-20mA
• Non Namur 4-20mA
Factory setting Non Namur 4-20mA
Additional information The measured value is defined by the "20mA Ch2" and "4mA Ch2"
parameters.
If the measured value is outside the measuring range, the device displays
the diagnostic message "Density range".
4mA Ch2
Description Use this function to enter a value for the 4 mA current.
User entry Decimal
Factory setting 0 (°C)
Additional information Positive and negative values are permitted depending on the process
variable assigned in the "Assign" parameter. In addition, the value must be
smaller than the value assigned for the 20 mA current in the "20mA Ch2"
parameter.
The unit depends on the process variable selected in the "Assign"
parameter. The permitted value range is indicated in Nanomass
Communication with the "Min" and "Max" fields.
20mA Ch2
Description Use this function to enter a value for the 20 mA current.
User entry Decimal
Factory setting 20 (°C)
Additional information Positive and negative values are permitted depending on the process
variable assigned in the "Assign" parameter. In addition, the value must be
greater than the value assigned for the 4 mA current in the "4mA Ch2"
parameter.
The unit depends on the process variable selected in the "Assign"
parameter. The permitted value range is indicated in Nanomass
Communication with the "Min" and "Max" fields.
