Test Net Wrap Actuator Current

This test is used to determine the working condition of the actuator through its entire range of operation.

To test the actuator motor and linkage:

1. Turn the tractor ignition key to the ON position. Do not start the tractor engine.

2.

   A - Actuator Extend Softkey

   B - Actuator Retract Softkey

   Using the Actuator Extend softkey (A) and the Actuator Retract softkey (B), operate the net actuator through a full cycle. Observe the actuator current (C) on the monitor. During extension, the current flow must be between 1—8 Amps.
   • Below normal readings indicate low tractor voltage, or poor or corroded harness connections.
   • Above normal readings indicate binding linkage or partially shorted motor windings.
   • A current spike can indicate an obstruction or binding in the linkage.

6. Continue to extend the actuator to the end of the stroke. While the actuator is stalled, the current reading must be between 22—30 Amps. Check the stall current both on extension and retraction.

7. Select the Actuator Retract softkey and move the actuator to the home position.

8. Turn the tractor ignition key to the OFF position and remove key.
