Speed Transducer for Sprayer
The speed transducer and speed ring are located at the inside of the
sprayers right wheel. The sensor is an inductive type that requires a
metallic protrusion like a speed ring to pass by it to trigger a signal.
Adjustment
1. Assure that the speed ring is correctly fitted to the wheel, so that
the arrow (A) follows the forward rotation of the wheel.
2. Adjust so the sensor lines up in the middle of the gaps in vertical
direction. Distance from centre of the sensor to top of the brake
drum:
• 412 mm brake drum = 60 mm
• 400 mm brake drum = 75 mm
μ
ATTENTION! If necessary, readjust plate on the axle.
3. Adjust air gap (B) to 3 - 6 mm. Use a feeler gauge or similar tool.
÷
NOTE! Adjustment shall be made out of one of the carriage bolts for the speed ring.
4. After adjustment then spin up the wheel. Verify air gap variation less than +/-0.5 mm. Check this at the entire
circumference.
5. Verify speed at the controller.

ATTENTION! Correct fitting is indicated by continuous flashing from transducer, when the wheel rotates.
