Current overload protection to the twine actuator
is bypassed when using channel 018. Extended use of channel 018 can
cause actuator damage.
Channel 018 allows the operator to use the EXTEND key
(B) and the RETRACT key (C) to position the actuator for service.
-
Remove the roll of net wrap material from the baler
if testing the net actuator voltage. Otherwise, if the PTO is engaged
with the net actuator extended, net feeds into the empty baler and
can cause damage to the pickup or rotary feed system.
If testing net and wrap actuator current, remove the roll of
net wrap material from the baler.
-
Turn the tractor ignition key to the ON position. Do not start
the tractor engine.
-
Press and hold the COUNTER key (A) while turning the monitor-controller
ON.
-
Continue to hold the COUNTER key and press the PLUS key until CH018 appears in the digital display.
-
Release the COUNTER key; the digital display changes to show
the actuator static current flow reading of 0 to 1.
-
Use the EXTEND key (B) and the RETRACT key (C) to operate the
actuator in both directions. The display must show a current flow
reading between 1 and 8 while the actuator motor is operating during mid stroke
(no load).
-
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 spike in the current reading indicates a mechanical obstruction
to the linkage
-
Continue to operate the actuator to the fully retracted position.
The display must show a stall (load) current
reading between 22 and 30.
-
Below normal reading indicates bad or corroded harness connections
-
Above normal reading indicates partially shorted motor windings
or actuator binding
-
Press the RETRACT key to move the actuator to the home position.
-
Turn the monitor-controller OFF. Turn the tractor ignition key
to the OFF position and remove the key.
