A - Sowing Shaft Sensor

B - Blower Shaft Sensor

C - Land Wheel Sensor

D - Magnet

E - Lock Nuts

Sowing shaft sensor (A), blower shaft sensor (B) and land wheel sensor (C) require to be correctly adjusted for an accurate monitoring.

Sowing Shaft Sensor

Adjust distance between sensor (A) and magnet (D) as specified. Secure sensor with lock nuts (E).

Item	Measurement	Specification
Distance Between Sensor and Magnet	Maximum Distance	1.5 mm (0.06 in.)

Blower Shaft Sensor

Adjust distance between sensor (B) and cam to specification:

Item	Measurement	Specification
Distance Between Sensor and Cam	Maximum Distance	1.5 mm (0.06 in.)

Turn sensor (B) into blower shaft support until it contacts a cam and then turn back half a turn. Thus the specified distance is obtained. Check that cams will pass sensor freely. Secure sensor with lock nuts (E).

Land Wheel Sensor

Adjust distance between sensor (C) and rotating bar magnet (D) to specification. The south pole of the bar should then point toward the sensor. Secure sensor with lock nuts (E).

Item	Measurement	Specification
Distance Between Sensor and Rotating Bar Magnet	Maximum Distance	3 mm (0.12 in.)
