Description
Selection of status of the current output in error condition.
The output 'low' or 'high' current is set in the subsequent menu.
Sets the current for Low Alarm.
Sets the current for High Alarm.
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.
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 'Iout Mode' 4-20mA FWD / REV has been selected.
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 issued via digital output 41 / 42.
• Forward: Only pulses in the forward flow direction (flow in the direction of the arrow) are issued via digital output
41 / 42.
• Reverse: Only pulses in the reverse flow direction (flow opposite of the direction of the arrow) are issued via digital
output 41 / 42.
Selection of submenu '......Setup Pulse Output' using
Only available if 'Mode' Pulse has been selected.
Selection of submenu '......Setup Freq Output' using
Only available if 'Mode' Frequency has been selected.
Selection of submenu '......Setup Logic Output' using
Only available if 'Mode' Logic has been selected.
Selection of submenu '...Alarm Config' using
Only available when 'Mode' Logic is selected in the '...Setup Logic Output / Logic Output Action' Alarm Signal menu.
