NAS 1638 - National Aerospace Standard (Only CS 13xx)
The following NAS values can be read out via the analog output:
• NAS maximum
Only one value is output.
• NAS (2 / 5 / 15 / 25)
All values are sequentially time-coded before output.
• NAS 2 / NAS 5 / NAS 15 / NAS 25
Only one value is output in each case.
• NAS+T
All values are sequentially time-coded before output.
• HDA.NAS
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 0.0 … 14.0 (resolution 0.1 class) or an error as
shown in the table below:
Current I = NAS 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
