SETUP

CAUTION! An intensive magnetic field may be present, therefore, people with a pacemaker, hearing
aid and/or any other type of devices of this nature, MUST BE CAREFUL around the machine. The
magnets could affect these types of devices.
IMPORTANT! Because of the limitations of the system, there is an area at both ends of the lower feed roll
where the sensitivity is reduced. As the distance from the lower feed rolls increases, the detector’s
sensitivity also decreases.
IMPORTANT! The metal detector cannot and MUST not be expected to be a 100% fool-proof device.
IMPORTANT! The maximum performance of the metal detector system can be expected only if it is kept in
good operating condition and all parts are working correctly. As any electrical system, this unit is subject to
malfunction due to defects, occasional breakdowns, misuse and normal wear and tear.
NOTE: The metal detector is only sensitive to moving objects. For this reason, it is possible for an object to
pass very slowly over the detector “undetected”. Keep this in mind when manually checking the system.
NOTE: A poorly maintained or adjusted metal detector system causing multiple false detections may damage
drive components or cause other failures to the harvester.
DAILY CHECKS ON THE METAL DETECTOR
It is recommended to check the unit frequently, and at the beginning of each operating day, to be assured of
its proper working condition, using the following procedure
1. Check wire harnesses, connectors, connections, etc.
2. Check the stop pawl system for free motion. Check the alignment of the NEUTRAL/REVERSE sensors
and perform necessary adjustments.
3. Initialize the metal detection system by switching the power and alarm to ON and shifting the
transmission to REVERSE. Refer to the INITIALISATION section on page 68.
4. Shift the transmission to FORWARD and stop the PTO and disconnect the PTO shaft from the tractor.
Leave the metal detector, tractor engine and hydraulic flow On.
DANGER: Always turn off and disconnect the tractor PTO when performing this test.
5. Pass a metallic object between the front feed rolls in a quick backward and forward motion. The
solenoid should release the stop pawl onto the ratchet stop cam. The transmission should shift from
FORWARD to NEUTRAL automatically
6. The alarm, making an intermittent and slow “beep” and its indicator light should immediately come
ON if the system is operating properly. (Refer to the legend of alarms on the side of the control box)
7. Initialize the system as described previously to verify if it is operating normally.
8. If the system fails to operate, refer to the TROUBLESHOOTING section to determine the problem.
Make necessary repairs before proceeding any further.
DANGER: To prevent serious injuries or death from rotating feed rolls, do not service or make any
adjustments without first:
1. Stopping the PTO and shutting off the tractor engine.
2. Making sure that all parts inside the Forage Harvester have stopped rotating.
