With the hay indicator mounted on the baler and the wiring parts connected properly, the hay indicator kit is ready to operate. Power up the applicator and the sensors will automatically turn on. The applicators have to be in an operating mode such as AUTO MODE or MANUAL MODE to go into pause. Whenever the sensors see each other the applicator will automatically pause, ex. After exiting a windrow, the following screen will appear:

After entering the windrow, either the AUTO or MANUAL MODE operating screen will re-appear. This screen will remain until the baler picks up crop and the hay indicator’s signal is interrupted. Note: the MAIN MENU key can be pushed to exit this screen as well.
