Refill Timeout
Error
The system was unable
to refill in less than 30
seconds.
Check hopper for adequate material and material blocking.
Verify the vacuum transfer system air pressure is 40-80 psi (60 psi rec-
ommended) and that air is flowing to the feed wand while attempting to
refill.
Restart system. If the error persists after attempting another refill and
unit is needed immediately for production, place system into the man-
ual refill mode. See Manual Refill on page 30.
