Levelflex M FMP40 4...20 mA HART
The basic setup is sufficient for successful commissioning in most applications.
The Levelflex is precalibrated at the factory to the probe length ordered so that in most cases
only the application parameters that automatically adapt the device to the measuring conditions
need to be entered. For models with a current output, the factory adjustment for zero point and
span F is 4 mA and 20 mA, for digital outputs and the display module 0 % and 100 %.
A linearization function with a maximum of 32 points, which is based on a table entered
manually or semi-automatically, can be activated on site or via remote operation. This function
makes it possible to convert the level to volume and mass units and has a uniform effect on the
interface and the total level.
Complex measuring operations necessitate additional functions that the user can use to
customize the Levelflex as necessary to suit his specific requirements. The functions available to
do this are described in detail in BA366F – "Description of Device Functions" on the enclosed
CD-ROM.
Comply with the following instructions when configuring the functions in the
"basic setup" (00):
• Select the functions (see Operating Instruction on the CD-ROM).
• Certain functions (e.g. starting an interference echo mapping (053)) prompt you to confirm
your data entries. Press
started.
• If you do not press a key during a configurable time period (→ function group "Display (09)")
an automatic return is made to the home position (measured value display).
!
Note!
• The device continues to measure while data entry is in progress, i.e. the current measured
values are output via the signal outputs in the normal way.
• If the envelope curve mode is active on the display, the measured values are updated in a
slower cycle time. Thus, it is advisable to leave the envelope curve mode after the measuring
point has been optimized.
• If the power supply fails, all preset and configured values remain safely stored in the EEPROM.

Caution!
All functions are described in detail, as is the overview of the operating menu itself, in
BA366F - "Description of Device Functions" on the enclosed CD-ROM.
