Check PTO and Lower Drive Roll Speed (Channels 016 and 017)

The following procedure is not used on a 450M or 550M Baler with a regular pickup.

Use speed readouts to verify the proper operation and adjustment of sensors. Access channel 016 on the monitor-controller for PTO speed and channel 017 for the pickup drive speed.

   PTO Speed Sensor

   
   E85280-UN-27OCT17

   Lower Drive Roll (Pickup) Sensor

   A - Clutch Lobe (6 used)

   B - Sensor

   C - Sprocket

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

   Adjust the PTO sensor closer to clutch lobes (A) but not closer than 1 mm (0.04 in). Adjust the pickup sensor (B) closer to the sprocket (C) but not closer than 3 mm (0.12 in). Ensure that the sensor is aligned with the passing holes in the sprocket.

   When the tractor is operated at rated PTO speed, channel 016 must display 540 rpm or 1000 rpm, depending on the speed option. Channel 017 must display approximately 310 rpm for the MegaWide™ Plus pickup and 170 rpm for the MegaWide™ HC2 feed system. The slip clutch alert system must be activated within the monitor-controller for proper operation.

   Turning the PTO speed sensor ON and OFF:

   • Access channel 204.
   • To turn the PTO speed sensor feature ON, set the value to 540 for the 540 rpm option or 1000 for the 1000 rpm option.
   • To turn the feature OFF, set the value to 0.
   
   

   Turning the pickup speed sensor ON and OFF:

   • Access channel 205.
   • To turn the pickup speed sensor ON, set the value to 310 for the MegaWide™ Plus pickup or 170 for the HC2 feed system.
   • To turn the pickup speed sensor OFF, set the value to 0.
   • Turning OFF the pickup sensor on channel 205 and turning ON the PTO sensor on channel 204 still allows automatic speed compensation during the wrap cycle.
