Drawing Number: H-516 Sheet 2
A. Dump solenoid de-energized (open) while
outside cut cycle. (Motor and pump run
continuously.)
The hydraulic motor drives the pump
continuously. When the cut cycle is initiated,
the dump solenoid energizes (closes), and the
knife latch is retracted.
B. Energize two CUT solenoids. (Knife and
Clamp are sent down.)
When the CUT solenoids are energized, oil will
flow freely to the knife down (KD) cylinder port
and through the pressure reducing valve to the
clamp down cylinder port (CD). Both CUT
solenoids must energize to continue the
sequence. Since oil is restricted by the knife
sequence valve and blocked by a check valve,
the knife will stay up, and the clamp will start
down. When the clamp stops downward
motion, the system pressure will rise. Pressure
in the clamp down line will level off to the
setting of the pressure reducing valve. The
system pressure will continue to rise until the
knife sequence pressure valve opens allowing
the knife to come down. The knife will continue
down until the cylinder reaches the extreme of
its travel. System pressure will increase until
the main system relief valve trips. At this time,
the electronics will sense that the knife is down,
and de-energize the CUT solenoids.
C. De-energize two CUT solenoids. (Knife and
Clamp are sent up.)
With the CUT solenoids de-energized, oil flow
is directed to the knife up cylinder port (KU)
and the clamp up cylinder port (CU). Since the
clamp down port (CD) is blocked by a check
valve and the clamp up sequence valve the
clamp will stay down while the knife goes up.
When the knife reaches the up extreme,
system pressure builds until the clamp up
sequence valve opens and allows the clamp to
move up. System pressure will increase until
the main system relief valve trips. At this time,
the electronics will sense that the knife and
clamp are up and de-energize the dump
solenoid sending oil flow back to the tank. The
knife latch is engaged.
