Level Sensor
Error
Failure of the level sen-
sor (20) or sensor
cable 16T108 (J14 to
level sensor (20)).
Check sensor cable J14 to level sensor (20).
Enable Diagnostic screen on ADM then check sensor readings on the
Diagnostic screen. Sensor readings should be about 4.3V if melter is
completely empty (melter passage holes are visible). The normal oper-
ating range is 3.8 to 4.3V. If the sensor is reading more than 4.2V the
system should be requesting additional material.
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
on page 30.
The InvisiPac
system expels
adhesive pel-
lets dust when
refilling.
Some adhesives are
very dusty due to the
anti-blocking agents
used or because the
adhesive manufactur-
ing process has cre-
ated small adhesive
shavings. Feed inlet
cap filter may have
become clogged.
NOTE:
Feed cap filter maintenance should be performed at regular
service intervals. It is recommended that the feed cap filter be
inspected at a minimum of every 1200 lb dispensed, however with
some adhesives the frequency may need to be increased significantly
to maintain desired system cleanliness.
The InvisiPac
system will not
stall, pump
continues to
move even if
the applicators
are all closed.
Fluid leak.
Verify that no external leakage is present.
Inspect and test the pressure relief valve.
Perform
Flush Pressure Relief Valve
, page 54.
If system is still unable to stall, the pump or pressure relief valve may
need to be repaired.
The system
will not dis-
pense mate-
rial.
System is not up to
temperature.
Verify that the system is active.
Incorrect temperature
set points entered into
ADM.
Verify the temperature settings are correct.
Air motor is not receiv-
ing compressed air or
air pressure too low.
Verify that the pump air pressure is set above 20 psi.
Feed pump not feed-
ing adhesive.
Repair or replace air control assembly as necessary.
Repair or replace pump assembly as necessary.
Timing control for appli-
cators not working.
InvisiPac system does not control the timing of the applicators. This is
a separate control that needs to be adjusted. Consult control manufac-
turer or qualified electrician.
Cycle Switch
Error
Cycle switch or cycle
switch wiring failure.
Check the wiring between the air motor cycle switch and J16.
Repair/replace as required.
Loose or missing fas-
tener (26).
Ensure fastener (26) is tight. See
section begin-
ning on page 83 for part identification.
