When the Validator is enabled the Inhibit Line is Low and the Busy Line is High. This remains the same until a note is
inserted (Time A). When a note is inserted under the front sensor the BV30 wakes up and the busy line goes low to
indicate that the validator is in use. The busy line remains low during the validating and stacking process and once
the note has been successfully validated and stacked the vend line goes low to issue the credit. After the credit is
issued the busy line goes high and approximately 1 second after
the busy line goes high (Time B) the BV30 goes back into low power mode.
