GBR 420 Inserter Screen List Diagnostic Description
Overview:
The GBR 420 Inserter Interface passes a pack to the inserter track at an
open station or a gripper arm.
Once the pack is sensed “In Track”, the pack is tracked through the inserter
stations by indexing the data one station at a time when a Demand Feed
Signal is received from the inserter at each cycle. The Inserter Interface
performs an inserter action based on the pack data at a particular station.
If a pack at Select Station 1 requires material from Select Station 1 the the
Inserter Interface enables the vacuum at that station. This control applies to
Select Station 1 to Select Station 8 and the envelope station.
