Loop Current Mode
Display of the operating mode (only for 31
/ 32 Uco current output).
•
Multidrop Fixed: The current output is in HART multi-drop mode, the current output is fixed to 3.6 mA and no longer
follows the selected process variable. The process value is still transmitted through the HART protocol.
•
Normal Signaling: The current output transmits the selected process value, and the process value is additionally
transmitted through the HART protocol.
•
Power Mode: The current output 31/32/Uco is set permanently to 22.6 mA and no longer follows the selected process
variable. HART communication is deactivated. The current output 31/32/Uco works as a power supply unit for the
operation of the digital output 41 / 42 as an active output. See chapter Current output Uco / 32 as loop power supply
for digital output 41 / 42 or 51 / 52 on page 58.
Output Value
Selection of process variable issued at the corresponding current output.
Refer to Available process variables
on page 98.
Curr.Out Mode
Select the operating mode for the current output.
•
‘4-20mA FWD’: Output flow rate in the forward flow direction:
4 mA = no flow rate, 20 mA = maximum flow rate).
Curr.Out at
Alarm
Selection of status of the current output in error condition.
The output ‘low' or ‘high’ current is set in the subsequent menu.
Low Alarm
Sets the current for Low Alarm.
High Alarm
Sets the current for High Alarm.
Curr.Out > 20,5mA
Behavior of current output if 20.5 mA is exceeded.
•
Hold Last Value: The last measured value is retained and issued.
•
High Alarm: The high alarm current is issued.
• Low Alarm: The low alarm current is issued.
Curr.Out < 3,8mA
Behavior of the
current output if 3.8 mA is not reached.
•
Hold Last Value: The last measured value is retained and issued.
•
High Alarm: The high alarm current is issued.
•
Low Alarm: The low alarm current is issued.
