The OR2‑M is set up to transfer the injection
molding machine from the velocity stage to the
pressure stage in the cycle. The OR2‑M must
be set up in the Sensor Locations.
To test if the input is detected by the machine,
use the V
→
P Output Test function. The Velocity
to Pressure Transfer tool Output Test function
is accessible from the Settings menu. Select
Output Test, then press the on and off buttons
and check the press controller’s diagnostic page
for changes in the input. The
eDART disables the
test button when the press is cycling.
If the inputs are correct and detected by the
machine, perform the following to ensure the
correct function:
Set up a process (DECOUPLED MOLDING
®
II
or III) with transfer from pressure to hold based
on the machine’s screw position.
Make sure the process ends with little cushion,
likely bottoming out shortly after transfer—this
will prevent mold damage if the transfer does
not work.
Make a template.
Place the cursor on the Cycle Graph slightly
before the machine pressure curve can be seen
dropping into hold.
Record the volume measurement from the
cursor. Open the V
→
P tool and select the check
mark next to the “Injection Volume Exceeds”
field to enable control; enter the recorded
volume measurement and select the correct
units of measure.
Enable the machine’s external transfer; some
machines allow both external and internal and
some force the use of only one or the other.
The V‑>P volume switchover should show
“Active” and the machine should transfer earlier
as shown below
The transfer point should be movable by
changing the volume number in the V
→
P tool.
If the curve does not change from the template
(as shown below) then the machine is not
accepting the transfer signal from the
eDART
.
The backup set points for time, position, or
pressure on the machine must be verified and
used during cavity pressure transfer control.
In the event that the cavity pressure transfer
control input is not detected by the machine
controller, the backup set points prevent
damage to the tool.
