0x001A / 26
Sampling error
External fault
An incorrect data frame exists, i.e. the
data frame is not terminated with zero
(possible wire break of clock lines).
SSI has no power supply or data line
break, or D+ and D- have been inverted.
75x-635
OTHER
0x0009 / 9
Error
Wave speed not set
or
inadequate stop pulses
or
the maximum wave speed exceeded
or
timeout, no measurement values exist,
measurement value invalid
or
error when setting the wave speed or zero
point has occurred
or
invalid transmitter selection, the selected
transmitter address is invalid because of
the missing initialization
