Abstract
Systems and methods for reporting a position of an air-over-hydraulic road treatment element use pneumatically activated switches triggered by pilot air for moving the road treatment element. Switch activation electrical signals are used to determine whether the road treatment element is in an engaged configuration or a disengaged configuration. If the switch activation electrical signals indicate the engaged configuration, an engaged configuration electric signal can be maintained until the switch activation electrical signals indicate the disengaged configuration. Conversely, if the switch activation electrical signals indicate the disengaged configuration, a disengaged configuration electric signal can be maintained until the switch activation electrical signals indicate the engaged configuration. The engaged configuration electric signal can be maintained even after cessation of the switch activation electrical signals indicating the engaged configuration, and similarly the disengaged configuration electric signal can be maintained even after cessation of the switch activation electrical signals indicating the disengaged configuration.
