Y:
learn pressure limit according to selected DATA TYPE,
nominal pressure range is 0 … 10’000 (sensor full scale) but it may be scaled,
refer also to command GAIN for details.
This command transfers/reads the pressure limit for LEARN.
Refer to «LEARN (setup step 5)» for correct learn pressure limit setting.

X:
index (000 .. 103, whereas these indices must be ASCII coded,
e.g. 000 = 30h 30h 30h, 001 = 30h 30h 31h, etc.)
Y
8 data bytes ASCII coded (e.g. 30h 32h 33h 33h 33h 30h 33h 36h)
Example of XY: 30h 30h 30h 30h 32h 33h 33h 33h 30h 33h 36h (11 bytes in total)
This command loads the learn data sets from the host down to the valve. There are a total
number of 104 data sets. Each data set needs to be downloaded separately.

This command loads the learn data sets from the valve up to the host. There are a total
number of 104 data sets which need to be uploaded separately. Each answer consists of 11
bytes. Whereas the leading 3 bytes are the data set index followed by 8 data bytes. Data
are ASCII coded.
Unless otherwise specified all values in the table above are in decimal notification. Hexadecimal values
are indicated by the letter ‘h‘ (e.g. 31h)
