The second part (positions 24 to 40) is optional as a whole enabled with EEPROM bit

EE_ExtendedSequence.

This second part consists of the error code (8 occurences), 8 OEM -defined Code

The temperature can be derived from SENT ID 23, TEMP sensor, with the following equation:

SENT@ ID 23 = 8 * (T[C] – 35[C]) + 865 lsb12

The accuracy of the actual Temperature is = ± 10 DegC.

14.3.3.1. Error Code Rate

The Error Code are on purpose transmitted every second message, to maximize the rate, which equals

then 36 SENT frames.

14.3.4. Serial Message Error Code

The list of error and status messages transmitted in the 12-bit Enhanced Serial Message data field when

Enhance Serial Message ID is $01 is given in the following Table.

12 Bit Data

$000

No error

$801

GainOOS

Front-end Gain code Out-of-spec (too low, too high)

$808

ADCSatura

In case multiple errors occur, then the resulting 12 bit enhanced serial message data will be the OR-operation of the

individual data values. Example $809 = GainOOS + ADCsatura
