    A - Clutch Fins

    B - Tone Wheel

    If speed variation exceeds ± 5 rpm, shut off tractor engine and remove key.

    Adjust PTO sensor closer to clutch fins (A) but not closer than 1 mm (0.04 in.). Adjust pickup sensor closer to tone wheel (B) but not closer than 3 mm (0.12 in.).

    When tractor is operated at rated PTO speed, channel 016 must display either 540 rpm or 1000 rpm. Channel 017 must display approximately 310 rpm. Slip clutch alert system must be activated within the monitor-controller for proper operation.

    Turning PTO Speed Sensor ON and OFF:

    • PTO speed sensor can be turned OFF or ON by accessing channel 204.
    • Feature can be turned ON by changing value to 540 or 1000 rpm.
    • Entire slip clutch alert feature can be turned OFF by changing value to 0.

    Turning Drive Roll Speed Sensor ON and OFF:

    • Pickup rpm sensor can be turned OFF and ON by accessing channel 205.
    • Feature can be turned ON by changing value to 310 rpm.
    • Pickup rpm sensor can be turned OFF by changing value to 0.
    • Turning OFF the drive roll sensor on channel 205 and turning ON PTO sensor on channel 204 still allows automatic speed compensation during wrapping cycle.
