P05: Lower (learning) level of the operating range
Programming this parameter 0% of level will be assigned to the capacitance measured in the actual application i.e. the unit will “learn” conditions
of the application
Programming can be started by double key pressing of
+
. While learning „Store” will be first displayed and then 0%
P06: Upper (learning) level of the operating range
Programming this parameter 100% of level will be assigned to the capacitance measured in the actual application i.e. the unit will “learn”
conditions of the application
Programming can be started by double key pressing of
+
. While learning „Store” will be first displayed and then 100 %
If level, level percentage, volume or volume percentage should be measured (a
•
0 in P01) as well as level and volume should be read with relevant
engineering units, then first data pair (e.g. 0% and corresponding minimum level in
[
m
]
and last two data pair (e.g. 100% and corresponding maximum
level in
[
m
]
of the linearisation table should be entered. Obviously linearisation must be switched ON. (See P47 and P48 on page 30)
Programming of partially filled tank
Not only the minimum (0%) and maximum (100%) level of the actual application can be assigned (directly) to the 4 and 20 mA output.
If for some reasons of the technology the tank can not be filled to the maximum or emptied to the minimum level the 4 and the 20 mA can (indirectly) also be
assigned to the minimum (0 %) and maximum (100 %) with the help of two intermediate levels (say to 15% and to 80%).
Obviously - for the sake of accuracy – it is advised to fill/empty the tank to the maximum/minimum level and perform “direct” assignment as soon as possible.
The unit can also be programmed for inverse operation (4 mA = full and 20 mA = empty).
