Output Value
Selection of process variable issued at the current output.
•
Qm [%]: mass flow
•
Qv [%]: volume flow
Curr.Out Mode
• Selection of operating mode for the current output.
• ‘4-20mA FWD’ Flow output in forward flow direction:
4 mA = no flow
20 mA = maximum flow
• ‘4-12-20 mA’: Flow output in forward and reverse flow direction:
4 mA = maximum flow in reverse flow
12 mA = no flow
20 mA = maximum flow in forward flow
•
‘4-20mA FWD/REV’: Flow output in forward and reverse flow direction without distinguishing between
flow directions:
4 mA = no flow
20 mA = maximum flow
Default setting: 4-20mA FWD/REV.
Curr.Out at Alarm
Selection of status of the current output in error condition.
The output ‘low alarm' or ‘highalarm’ current is set in the subsequent menu.
Default setting: High Alarm.
Low Alarm
Sets the current for Low Alarm (3.5...3.6mA).
Default setting: 3.5 mA
High Alarm
Sets the current for High Alarm (21...22.6mA).
Default setting: 21.8 mA
Curr.Out > 20.5mA
Behavior of the 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.
Default setting: Hold Last Value
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.
Default setting: Low Alarm
Curr. at EPD Alarm
Behavior of the current output during empty meter tube conditions.
• Off: No effect on current output.
•
Q=0%: Current output is set to 4mA which is "no flow".
•
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.
Default setting: Off
