Levelflex M FMP40 with HART/4...20 mA

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 as described on → ä 34.
• Certain functions (e.g. starting an interference echo mapping (053)) prompt you to confirm your
O S
data entries. Press or
• 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.
