Description
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.
• Parameter is not available if the parameter 'Curr.Out Mode' 4-20mA FWD/REV has been selected.
Default setting: Low Alarm.
Behavior of the current output with an empty meter tube.
• Off: no effect on current output.
• Q = 0%: Current output is set to 4 mA, 'no flow'.
• High Alarm: The high alarm current is issued.
• Low Alarm: The low alarm current is issued.
Default setting: Off.
TFE alarm (complete filling alarm) is issued when the meter tube is partially filled.
• Off: no effect on current output.
• Q = 0%: Current output is set to 4 mA, 'no flow'.
• High Alarm: The high alarm current is issued.
• Low Alarm: The low alarm current is issued.
Default setting: Off.
Selection of the operating mode for the digital output 41 / 42.
• Off: Digital output 41 / 42 deactivated.
• Logic: Digital output 41 / 42 as a binary output (e.g. as an alarm output).
• Pulse: Digital output 41 / 42 as a pulse output. In pulse mode, pulses are output per unit (e.g. 1 pulse per
m3).
• Frequency: Digital output 41 / 42 as a frequency output. In frequency mode, a frequency is issued that is
proportional to the flow rate. The maximum frequency can be configured in accordance with the upper
range value.
Selection of flow direction in which the pulse / frequency output issues the selected process value.
• The parameter is only available if the digital output has been configured as a pulse or frequency output.
• Forward & Reverse: Pulses for both flow directions are output via digital output 41/42.
• Forward: Only pulses in the forward flow (direction) (flow in direction of arrow) are output via digital out-
put 41 / 42.
• Reverse: Only pulses (in the) reverse flow (direction) (flow in opposite direction to arrow) are output via
digital output 41 / 42.
Selection of submenu '...Setup Pulse Output' using
Only available if 'ModePulse' has been selected.
Selection of submenu '...Setup Freq Output' using
Only available if 'ModeFrequency' has been selected.
Selection of submenu '...Setup Logic Output' using
Only available if 'ModeLogic' has been selected.
Selection of submenu '...Alarm Config' using
Only available when 'Logic' Mode is selected in the 'Alarm Signal' ...Setup Logic Output / Logic Output Action
menu.
