84 BM 102
To set the level theshold, we recommend the following filling height:
• Minimum height: 300 mm or 12 ” above the probe tip or the upper weight,
• Maximum height: distance to flange at least 500 mm or 20 “
Fct. Input distance
This function is used to search for the level signal at a pre-configured distance. The current output
is set to the appropriate value directly after the distance has been input.
Note:
If the function is executed during normal operation, this may possibly have
consequences on downstream systems.
Fct. Search end of probe
This function automatically defines the probe length. It is used, for example, after the probe has
been shortened. The tank needs to be empty when this function is executed. If the probe tip is not
found, possibly a level threshold has been set that is too high. Set the threshold to a lower value
so that the reflection signal from the probe tip can be identified.
Fct. Current output tests
This function is used to check the accuracy of the analog output by means of a milliammeter. For
this test a milliammeter must be connected into the loop. The following current values to be
generated can be selected: 4/8/12/20/22 mA.
