System functions
4.4 Data recording
4.4.1 Data channels
The EMS 2 contains a maximum of 32 memory domains, in which a maximum of 32 measurement and cal-
culation values (speed, temperatures, pressures, fluid levels, output signals, etc.) can be recorded. Some of
these signals, e.g. charge air pressure and charge air temperature, can also be read in from engine governor
systems via the CAN interface. In the relevant memory domains, identical measurement signals with diffe-
rent sampling rates can be recorded (most rapid sampling rate 5 Hz).
Depending on the spacing of the measurement points, measurement value recording of up to several thou-
sand is possible. Either the current, maximum, minimum or the mean measurement values are recorded.
Depending on the engine model series and system expansion, values from the following table may be
recorded:
The EMS 2 is programmed with a sensible data recording configuration in the factory. Changes must be
coordinated with head office, and are only possible with SERDIA.
Data recording is only carried out whilst the engine is running.
The data are read out with SERDIA, and are available in a standard format for commercially available gra-
phics and evaluation programmes, e.g. Excel.
