Description of device parameters Waterpilot FMX21
108 Hauser
Description Set the upper-range value – reference pressure is present at the device. The pressure for
the upper current value (20 mA) is present at the device. Use the "Confirm" option to assign
the applied pressure value to the upper current value.
Prerequisite: Pressure measuring mode
Options • Cancel
• Confirm
Factory setting Cancel
Set URV
Write permission Operators/Service engineers/Expert
Description Set the pressure value, level or content for the upper current value (20 mA).
Factory setting • 100.0 % in Level measuring mode
• URL Sensor or according to ordering information in Pressure measuring mode
Startcurrent
Write permission Service engineers/Expert
Description Entry of the start current. This setting also applies in the HART Multidrop mode.
Options • 12 mA
• Max alarm (22 mA, cannot be set)
Factory setting 12 mA
Curr. trim 4mA
Write permission Service engineers/Expert
Description Enter the pressure value for the lower point (4 mA) of the current partial regression lines.
Using this parameter and "Curr. trim 20 mA", you can adapt the current output to the
transmission conditions.
Options Carry out the current trim for the lower point as follows.
• Select the "Current" option in the "Simulation mode" parameter.
• In the "Sim current" parameter, configure the "4 mA value".
• Enter the current value measured using the switching unit in the "Curr. trim 4mA"
parameter.
Input range Measured current ±0.2 mA
