The Metal Detector contains a Metal Stop System which is designed to prevent ferrous (containing iron) metal objects from entering the Forage Harvester Cutting Cylinder. It can be used with all approved mounted Attachments. When a ferrous metal object passes through the Magnetic Field over the Lower Front Feed Roll, a low voltage signal is sent to the Amplifier Box which is mounted on top of the Feed Roll Housing. When the signal reaches the Amplifier Box, an electrical contact is opened which, in turn, interrupts power to the Pawl Solenoid. The Feed Rolls are stopped immediately by the Stop Pawl. At the same time, the Electric Clutch opens to stop power to the Attachment and Feed Rolls.

NOTE: The optimum performance of your Metal Stop System depends on it being kept in proper operating condition and properly maintained. Like any other electrical system, the Metal Stop System is subject to malfunction due to defects, occasional breakdowns, misuse and human error. As with any mechanical device, components can breakdown or wear. Therefore, it is highly recommended that the system be tested daily.
When the Metal Stop System is functioning properly, the following ferrous metal objects can be detected: — hitchpins — scrap iron — bolts — wrenches — rake teeth — steel pipe — steel fence posts — plow points — sickle sections 908018/AP0499

The Metal Stop System is only sensitive to moving objects; keep this in mind when performing the test procedures. There is also an area, at the center and the ends of the lower Feed Roll, where sensitivity is reduced. Sensitivity also decreases as the distance from 30
