Unable to
achieve
25lb/hr melt
rate at the
desired adhe-
sive tempera-
ture.
The InvisiPac system
monitors temperature
within aluminum mass
of melter (202). As melt
rates exceed 20 lb/hr a
system temperature
offset may be required.
1. If the cycle rate is below 33 cpm and the system is still running away
increase the InvisiPac system temperature by 10°F over the current
set point, leave hoses and guns at desired set point.
2. If the pump continues to runaway or dive continue increasing tem-
perature by 10°F, do not exceed maximum temperature for the
material being dispensed.
NOTE: A 50 amp breaker is required in order to maximize startup and
flow rate performance. Set the breaker size used in the Setup screens.
NOTE: Some materials are more difficult to melt than others, therefore
it may be impossible to process them at a rate of 25 lb/hr. The InvisiPac
system was tested to achieve continuous melt rates of 25lb/hr when
dispensing standard EVA packaging grade adhesives in pellet form
with an InvisiPac system temperature of 375°F and hose and valve
temperatures of 350°F.
ADM not dis-
playing when
system turned
on
Main power circuit
breaker off or power
cord unplugged.
Turn main circuit breaker on or plug in power cord.
Cable on ADM
unplugged.
Reconnect ADM cable.
Connector on MZLP
board not plugged in.
ADM cable should be plugged into J6 of the MZLP board.
Bad 24VDC power sup-
ply.
Check output on power supply should measure 24VDC, if no voltage
reading replace power supply.
ADM defective. Replace ADM.
Main breaker
tripping
Wrong setting in ADM
breaker setup.
Wrong breaker setting on ADM in the breaker setting in the setup
screen.
Internal short to ground
in system.
Unplug or disconnect power and measure between each leg of the
power to ground. There should be an open resistance reading.
Too small of a circuit
breaker in main power
panel.
Consult qualified electrician for proper size circuit breaker.
