• Unscrew fully both captive knurled screws that are attached to the reject support bracket.
This releases the tray and flap. Hold the reject flap and pull the reject tray approximately
25mm away from the rotary solenoid. Disengage the reject flap from the shaft and remove
it. Pull the tray away from the solenoid until it is released.
• Wash the product chute, polycarbonate cover, reject tray and reject flap in a mild
detergent solution. Rinse and dry thoroughly.
• Either dust or lightly brush the remainder of the reject assembly to remove any loose
particles. Do not use any cleaning fluids.
• Ensure that all components are clean and dry before re-assembly.
• Reach under the reject support bracket and push vertically the two spring-loaded
shoulder screws that are furthest away from the solenoid. This allows the reject tray to
slide onto the dovetail clamps. Push the tray towards the solenoid shaft until the shaft
appears flush with the hole on the inside of the tray.
• Hold the reject flap at an angle of approximately 45˚ to the horizontal and locate the
headed pin held captive in the tray with the circlip. Now carefully push the tray
approximately 1.5mm towards the solenoid to engage the solenoid shaft and flap. Push
the tray fully home and release the flap. Re-tighten the two knurled captive screws to
secure the tray.
• Refit the polycarbonate cover on the reject tray.
• Loosen the two knurled knobs on the product chute and refit the chute in the original
position in the detector head. Tighten the two knurled knobs to secure the chute.
• Switch on the electrical supply to the metal detector.
• Check the reject operation and confirmation system.
NOTE: Do not operate the metal detector unless the infeed chute and the polycarbonate
cover are fitted in position.
