The InvisiPac
system is dis-
playing pump
runaway or
pump diving.
This error generally
occurs when the pump
cavitates due to
improper material load-
ing.
This can occur if the melt rate for the system is exceeded, resulting in
air entrapment within the incoming adhesive material and lower than
desired material temperature.
1.
Verify that the InvisiPac system is not exceeding (11 cpm- HM25,
22 cpm - HM50) by enabling the diagnostic screen.
2.
If the cycle rate is below (11 cpm- HM25, 22 cpm - HM50)and the
system is still running away increase the InvisiPac system tempera-
ture in small increments over the current set point.
3.
If the pump continues to runaway or dive continue increasing tem-
perature in small increments. Do not exceed maximum temperature
for the material being dispensed.
NOTE:
If air has become trapped in the pump, it can be purged by fol-
lowing the
NOTE:
Some materials are more difficult to melt than others and it may
be impossible to process them at the published melt rate. The InvisiPac
system was tested to achieve continuous published melt rates when
dispensing standard EVA packaging grade adhesives in pellet form
with an InvisiPac system temperature of 350°F and hose and applica-
tor temperatures of 350°F.
Level sensor blocked,
reading level incorrect.
Clean feed cap by fill sensor, make sure there are no adhesive pellets
blocking the sensor hole.
The system is not sup-
plying enough air to the
ultrasonic sensor ven-
turi.
Ensure supplied Air Filter Kit 24R707 is installed on system air inlet.
Perform a reverse pressure flush of the sensor venture orifice:
1.
Disconnect incoming air from InvisiPac system air inlet (108).
2.
Disconnect air tube poush-connect union (91) from ultrasonic sen-
sor air tube (35).
3.
Plumb 80-100 psi (550-690 kPa, 5.5-6.9 bar) to outlet end o air tube
union (91).
4.
Ensure air is flowing out of the InvisiPac system air inlet (108).
5.
Reconnect ultrasonic sensor air tube (35) to air tube union (91).
