Reading the analog output
SAE - classes acc. to AS 4059
The following SAE values can be read out via the analogue output:
• SAE A-D (SAEMAX)
Only one single value is output.
•
/ / C / SAE A 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 SAE contamination class being = 0.0 - 14.0 (resolution 0.1
class) or on an error, as described below:
