Register Designation Type Display / purpose
2203 “Warning threshold cont.
mode” level monitoring
UINT8 With continuous level monitoring:
Specification of a threshold value (as a [%] of the
maximum liquid level); if this threshold value is not
reached, a warning is generated by the level monitor
0 … 100%
2204 “Error threshold cont. mode”
level monitoring
UINT8 With continuous level monitoring:
Specification of a threshold value (as a [%] of the
maximum liquid level); if this threshold value is not
reached, an error is generated by the level monitor
0 … 100%

toring
BOO‐
LEAN
This setting enables the continuous level measure‐
ment unit to be selected
