Testing Twine or Net Wrap Actuator Current (Channel 018)

Current overload protection to twine actuator is bypassed when using channel 018. Extended use of channel 018 can cause actuator damage.

Channel 018 allows operator use of EXTEND key (B) and RETRACT key (C) to position actuator for service.

A - COUNTER Key

B - EXTEND Key

C - RETRACT Key

To Test Actuator (Motor and Linkage):

1. Remove roll of the net wrap material from baler if testing the net actuator voltage. If the PTO is engaged with the net actuator extended, the net feeds into the empty baler and causes damage to the pickup or rotary feed system.

   If testing net and wrap actuator current, remove roll of the net wrap material from baler.

2. Turn tractor key to ON position. Do not start tractor engine.

3. Press and hold COUNTER key (A) while turning monitor-controller ON.

4. Continue to hold COUNTER key (A) and press PLUS key until CH018 appears in digital display.

5. Release COUNTER key; digital display changes to show actuator static current flow reading of 0 to 1.

6. To operate the actuator in both directions, use the EXTEND key (B) and RETRACT key (C). Display shows a current flow reading from 1 to8 while actuator motor is operating during mid stroke (no load).

   • Below a normal readings indicate low tractor voltage, or poor or corroded harness connections
   • Above a normal readings indicate binding linkage or partially shorted motor windings
   • Current spike reading indicates mechanical obstruction to linkage
   
   

7. Continue to operate the actuator to the fully retracted position. Display shows stall (load) current reading from 22 to30.

   • Below a normal reading indicates bad or corroded harness connections
   • Above a normal reading indicates partially shorted motor windings or actuator binding
   
   

8. To move the actuator to the "home" position, press the RETRACT key (C).

9. Turn monitor-controller OFF. Turn tractor key to OFF position and remove key.
