Values
“On” and “Off” voltage levels
27V > High ("1”) > 3.6V
0V ≤ Low (“0”) < 1.00V
*
Ignition signal should be higher then 10V when ignition is turned On and drop
to 0v when ignition is turned OFF .
*
A 12V vehicle has battery voltage of 13.7V and 24V vehicle has battery voltage
of 27V.
**
The current consumption of the AWS depends on the vehicle system voltage (12
or 24V).
