What to do if my Graco InvisiPac Tank-Free HM25 Industrial Equipment pump is running away?
If the Graco Industrial Equipment pump is running away, it could be due to several reasons. First, check if the storage bin is out of adhesive and refill if necessary. Also, ensure the melter temperature is set correctly, according to the manufacturer's recommendations. Additionally, inspect the vacuum transfer hose or funnel for any blockages and clear them. Finally, examine the pump seals for wear or damage and repair them if needed.
What causes pump diving in Graco InvisiPac Tank-Free HM25 and how to fix it?
If the Graco Industrial Equipment pump is diving, it may be due to the storage bin being out of adhesive pellets; refill the bin. Also, the melter might be at an incorrect temperature, too low, so check the temperature setting and adjust it to the manufacturer's recommendation. A plugged vacuum transfer hose or funnel can also cause this, so clear any blockages. Additionally, check if the feed rate for dispensing is too high. Lastly, inspect the pump seals for wear or damage, and repair if necessary.
How to troubleshoot vacuum transfer not working in Graco InvisiPac Tank-Free HM25 Industrial Equipment?
If the vacuum transfer is not working on your Graco Industrial Equipment, first verify the vacuum transfer system air pressure is within 40-80 psi (60 psi recommended). Next, check that the air line is connected and not pinched, if air is at the system air gauge but not to the air shaker. If air is at the shaker but there is no feed, a plugged shaker unit may be the cause. Remove the shaker from the system and remove the plug.
What causes no current to the melter in Graco InvisiPac Tank-Free HM25?
If there's no current to the melter in your Graco Industrial Equipment, check fuses F1 and F2 on the MZLP with the daughter board. Also, ensure that J1 is plugged into the MZLP with the daughter board. The system also requires a hose connected to Channel 1 or the use of the optional Overtemperature Jumper, 16Y727.
How to troubleshoot a fill solenoid error on Graco InvisiPac Tank-Free HM25?
If you encounter a Fill Solenoid Error on your Graco Industrial Equipment, verify the wiring between J13 and the refill solenoid is not damaged. Restart the system.
How do I fix a cycle switch error on Graco InvisiPac Tank-Free HM25 Industrial Equipment?
If you're experiencing a cycle switch error on your Graco Industrial Equipment, it could be due to no signal from the air motor sensor. Check the wiring on J16 of the daughter board. Also, check for a loose cycle switch bolt and tighten it. If those steps don't solve the problem, consider replacing the cycle switch.
What does it mean when my Graco Industrial Equipment says 'Missing DB'?
If the Graco Industrial Equipment is showing a missing DB error, it means the system is not acknowledging the daughter board. This could be due to a bad connection between the daughter board and the MZLP board. Loosen the daughter board, re-seat it, then secure it. If the MZLP daughter board does not respond to adjustment, replace the daughter board.
How to troubleshoot high current in a Graco InvisiPac Tank-Free HM25 melter?
If the Graco Industrial Equipment melter is showing high current, measure the resistance to ground between the heater leads. Replace the band heater or rod heater if needed.
What should I do if there's unexpected current in gun X of my Graco InvisiPac Tank-Free HM25 Industrial Equipment?
If you are seeing unexpected current to gun X on your Graco Industrial Equipment, it could be due to unexpected current flow to gun X. Replace the MZLP. Also, check heater resistance and resistance to ground, and replace the heater if necessary.
