11.1.6.1 HDA.SAE Signal 1-4 Table
The current or voltage range is dependent on the contamination rating according to SAE=0.0 – 14.0
(resolution: 0.1 classes).
Current I SAE class / Error Voltage U
I< 4.00 mA Cable break U< 2.00 V
I = 4.00 mA SAE 0 U = 2.00 V
I = 4.11 mA SAE 0.1 U = 2.06 V
I = 4.23 mA SAE 0.2 U = 2.11 V
... ... ...
I = 5.14 mA SAE 1 U = 2.57 V
I = 6.29 mA SAE 2 U = 3.14 V
I = 7.43 mA SAE 3 U = 3.71 V
I = 8.57 mA SAE 4 U = 4.29 V
I = 9.71 mA SAE 5 U = 4.86 V
I = 10.86 mA SAE 6 U = 5.43 V
I = 12.00 mA SAE 7 U = 6.00 V
I = 13.14 mA SAE 8 U = 6.57 V
I = 14.29 mA SAE 9 U = 7.14 V
I = 15.43 mA SAE 10 U = 7.71 V
I = 16.57 mA SAE 11 U = 8.29 V
I = 17.71 mA SAE 12 U = 8.86 V
I = 18.86 mA SAE 13 U = 9.43 V
... ... ...
I = 19.77 mA SAE 13.8 U = 9.89 V
I = 19.89 mA SAE 13.9 U = 9.94 V
I = 20.00 mA SAE 14.0 U = 10.00 V
If the contamination rating according to SAE is known, the current I or voltage U can be
computed:
I = 4 mA + SAE class * (20 mA - 4 mA) / 14
U = 2 V + SAE class * (10 V - 2 V) / 14
If the current I or voltage U is known, the contamination rating according to SAE can be
computed:
SAE class = (I – 4 mA)*(14/16 mA)
SAE class = (U – 2.4 V)*(14/8 V)
11.1.6.2 HDA Status Signal 5 Table
The current or voltage of the output signal (5) is dependent on the status of the CS 1000 as shown in
the table below:
Current I Status Voltage U
I = 5.0 mA The CS is functioning correctly U = 2.5 V
