Icon Description
This mode allows the machine to operate in a fully automatic mode. It waits for a signal from the
press to begin dispensing material. It will dispense as long as the “Screw Rotate Signal” is present
and there is material left in the cylinders. Once the cylinder reaches a pre-determined refill point, it
will begin refilling. The screw rotate signal must turn off first before the machine will check if it
requires refilling.
This Purges A-Material through the system by applying air to the feed cylinders, opening the refill
valve, and the “A” outlet valve. The purge process continues as long as the “Screw Rotate Signal” is
active.
NOTE: Before resuming normal operation using a mold, be sure to run enough material through the
unit in Auto Mode that it begins to cure.
This purges B-Material through the system by applying air to the feed cylinders, opening the refill
valve, and the “B” outlet valve. The purge process continues as long as the “Screw Rotate Signal” is
active.
NOTE: Before resuming normal operation using a mold, be sure to run enough material through the
unit in Auto Mode that it begins to cure.
Allows the operator to fully control the unit through the use of buttons on the operator interface.
