    SETUP METAL DETECTOR GENERAL INFORMATION NOTE: Warranty coverage will not extend to consequential damages. The metal detector is used for stopping the feed rolls when ferrous material is detected between them. The metal detector antenna is mounted inside the lower front feed roll. When the system is working properly, the following or similar objects will be detected with approximately 95% accuracy: ...

  • Page 58: Daily Checks On The Metal Detector

    SETUP The metal detector can be set to 10 different sensitivity levels for best performance. It uses a variable threshold that adjusts itself to the harvest conditions (length of cut, vibrations, impacts, etc.) to maximize the detection power. In certain cases, the sensitivity can be reduced to minimize the risks of false detections in more difficult conditions (Heavy wear of the feed rolls for example).
  • Page 59 SETUP FIGURE 64 9. Follow the instructions on the screen ( ) and pass a piece of ferrous metal (wrench, steel wire, etc.) between the front feed rolls in a quick ‘in & out’ motion when prompted.

  • Page 61: Disabling The Metal Detector

    SETUP DISABLING THE METAL DETECTOR NOTE: Warranty coverage does not apply to damage or failures caused by the malfunction of or disabling of the metal detector. When the metal detector fails to operate, it can be useful to by-pass the system in order to complete a full harvest day. However, when doing so, it must be taken into consideration that this is an emergency and exceptional situation.

  • Page 62: Drive Failure Detector

    SETUP DRIVE FAILURE DETECTOR FIGURE 68 FIGURE 69) One of the speed sensors measures the speed of the cutter head ( and is required by different functions of the harvesters. The drive failure detector compares the speed of the cutter head with the speed of the tractor PTO. If the shear bolt on the cutter head shaft breaks (or optional friction clutch slips), its speed will quickly decrease with respect to PTO speed and the controller will detect it.

  • Page 63: Failsafe Mode

    SETUP FAILSAFE MODE FIGURE 70 In the event of a feed roll sensor failure, the controller does not obtain the feed roll motor speed feedback required to operate the harvester at constant length of cut. The FAILSAFE mode (item 1 and 2) enables a manual override of the controller logic to allow the operation of the harvester without downtime until the sensor issue can be resolved.
