Caution!
The basic setup is sufficient for successful commissioning in most applications.
The Levelflex is initially adjusted 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 digital outputs and the display module, the factory adjustment for zero point
"E" and span "F" is 0 % and 100 %.
A linearization function with max. 32 points, that is based on a manually or semi-automatically
input table, can be activated on-site or via remote operation. This function enables, for example, the
conversion of the level into units of volume or weight.
Note!
The Levelflex M allows to check for broken probe. On delivery, this function is switched off,
because otherwise shortening of the probe would be mistaken for a broken probe.
In order to activate this function, perform the following steps:
1. With the probe uncovered, perform a mapping ("range of mapping" (052) and "start
mapping." (053)).
2. Activate the "broken probe det" (019) function in the "safety settings" (01) function
group.
Complex measuring operations necessitate additional functions that the user can use to customise
the Levelflex as necessary to suit his specific requirements. The functions available to do this are
described in detail in the BA00245F/00/EN.
Comply with the following instructions when configuring the functions in the "basic setup" (00):
• Select the functions as described, → ä 25.
• 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 optimised.
• If the power supply fails, all preset and parameterised values remain safely stored in the EEPROM.
• All functions are described in detail, as is the overview of the operating menu itself, in the manual
"BA00245F – Description of Instrument Functions" on the enclosed CD-ROM.
