SAE classes acc. to AS 4059
The following SAE values can be read out via the analog output:
•
SAE A-D (SAEMAX)
Only one single value is output.
•
SAE A / B / C / D
All values are sequentially time-coded before output.
•
SAE A / SAE B / SAE C / SAE D
Only one value is output.
•
SAE+T
All values are sequentially time-coded before output.
•
HDA.SAE
All values are sequentially time-coded before output.
This signal is planned for the HDA 5500, but it can be used also in other
applications.
The current 4.8 … 19.2 mA or voltage 2.4 … 9.6 V of the output signal is dependent
on the ISO contamination class SAE = 0.0 … 14.0 (resolution 0.1 class) or an error
as shown in the table below:
Current I = SAE class / Error Voltage U =
I < 4,00 mA Cable break U < 2,00 V
4.0 mA < I < 4.1 mA Device error, device not ready 2,00 V < U < 2,05 V
4,1 mA < I < 4,3 mA Not defined 2,05 V < U < 2,15 V
4,3 mA < I < 4,5 mA Flow error
(The flow rate is too low.)
2,15 V < U < 2,25 V
4,5 mA < I < 4,8 mA Not defined 2,25 V < U < 2,40 V
