Fill System Verification
Checklist
Follow this checklist to troubleshoot common refill or
dispensing-related errors.
✓ Check air filter by removing quick turn cap on top of
funnel. Clean or replace if needed. See Inspect the
Funnel Cover and Funnel Filter, page 32.
✓ Remove funnel cover and inspect. Remove stuck
debris if needed. Ensure level sensor sight tube is clear
of debris. See Inspect the Funnel Cover and Funnel
Filter, page 32.
✓ Verify level sensor readings on diagnostic screen are
consistent and slowly increase as material is
dispensed.
✓ Verify air supply to system is strong and between 50
and 100 psi (80 to 100 psi preferred).
✓ Inspect air line and vacuum tubing to feed bin. Dips
or kinks in the vacuum tubing can lead to a blocked
flow path.
✓ Check number of pump cycles in between refills (8 to
10 cycles is desired). Short fills of 3 or fewer cycles can
be caused by clogged funnel filter or debris in funnel.
✓ Monitor pellet flow and time to refill. Refills in excess
of 15 seconds can be caused by low adhesive level in
feed bin, insufficient air pressure, restricted feed hose,
or clogged funnel filter.
✓ Verify size and shape of adhesive being fed is
compatible with feed system and that melt rate ability is
not exceeded.
✓ Check if glue is excessively dusty or releases oily
vapor when heated. Fill system maintenance will be
minimal given typical glue selection.

Power Input Verification
Checklist
This equipment can be powered by more than 240V.
Contact with this voltage will cause death or serious
injury. Turn off and disconnect all power before
servicing electrical components.
Follow this checklist to troubleshoot common
power-related errors.
✓ Verify that the wires are tightly secured into the
electrical disconnect.
✓ Confirm wiring matches label on electrical
disconnect.
✓ Measure incoming line voltage. For a transformer
system, also measure transformer output voltage at the
terminal block.
✓ Verify power connections to J22 on the AMZ circuit
board are fully seated.
✓ Check internal wiring against the Electrical
Schematics, page 105.
