PRINCIPLES OF OPERATION
OPERATING CHARACTERISTICS FOR:
V-6030HD, V-4830HD, V-6030LP, AND V-7230HD
When the AUTOCYCLE button is depressed, a contact is made that energizes the motor starter
coil, starting the electric motor and at the same time energizing T1 timer coil, T2 timer coil, and
R1 relay coil. When R1 is energized, the hydraulic oil is directed by the directional control valve
from a signal to the solenoid that shifts the valve. The oil is directed to extend the cylinder and
lower the platen. When T2 times out, the contacts reverse. This de-energizes R1 which causes
the down solenoid to de-energize, and the up solenoid to energize. Oil is directed to the rod end
of the cylinder and the platen is raised. As the platen reaches the full up position, the baler feed
gate opens. Opening the feed gate causes the magnetic interlock contact to open which stops
power to the motor starter coil and shuts the baler down. If the feed gate fails to open, the T1
timer will time out and break power to the motor starter coil, shutting the baler down.
NOTE: The BALE MADE LIGHT will be illuminated if the T2 timer times out while the BALE
MADE limit switch is activated. When this happens, the motor will stop with the platen in the
down position.

NOTE: When the platen dwells in the down position with the arrow on the platen in line with the
arrow on the NOTICE decal on the feed gate, it is time to tie the bale. See Bale Tie Off instruc-
tions on page 1-15.
