Abstract
Various embodiments for determining a voltage rating of a solenoid in an electropneumatic valve are disclosed. A braking system controller comprises a power switch electrically connected to an associated first solenoid. The power switch provides a low current regulated voltage to the associated first solenoid. The current through the solenoid is converted to a voltage. The voltage is compared to a predetermined voltage range to determine the voltage rating of the associated first solenoid. In another embodiment, the control logic is capable of determining the voltage rating of multiple solenoids in each of the electropneumatic valves connected to the controller.
