Setup

Grounding

The equipment must be grounded to reduce the risk of static sparking and electric shock. Electric or static sparking can cause fumes to ignite or explode. Improper grounding can cause electric shock. Grounding provides an escape wire for the electric current.

The InvisiPac system is equipped with a ground terminal. A qualified electrician must ground the system using this terminal. See Connect Electrical Cord on page 23.

NOTICE

To prevent excessive static buildup on shaker or adhesive bin, install optional grounding kit 24R708.

The applicator(s) must be located no more than 25 ft (7.6 m) from the melter.

Place the base system on a surface that is eye-level for easiest operation. Use System Stand, 24R088, to install system at eye-level. See page 102.

If installing the system in place of a non-Graco hot melt system, purchase Adapter Plate, 24R083. See page 102.

Optional 30 Gallon Vibrating Hopper, 24R136, available (purchase separately). See page 104.

To make repairing the system easier, locate the system so that all sides are easily accessible and have sufficient lighting.

208V Electrical Circuits

For 208V electrical supply, a qualified electrician can install a 208V to 240V step-up transformer to improve startup times.

Transformer Sizing

Minimum transformer rating can be calculated by taking transformer output voltage times the ADM breaker setting.

Single Phase, 20A ADM Breaker Setting Example:

240 volts x 20 amps = 4800 watts

Three Phase, 20A ADM Breaker Setting Example:

240 volts x 20 amps x SQRT(3) = 8315 watts

Select ADM Settings

NOTE: See Appendix A - ADM on page 114 for

detailed ADM information, including general operation.

NOTE: An incorrect RTD setting will cause the system to be incapable of maintaining the temperature setting.

NOTE: The supported RTD types are Ni, 100 ohm; Ni, 120 ohm; NiFe, 604 ohm; Pt, 100 ohm (385), Pt, 100 ohm (392); and Pt, 1000 ohm. An “Auto” selection is available but should only be used when the specific RTD type cannot be identified. Using the “Auto” RTD setting may result in inaccurate temperatures.

To prevent fire and explosion, a qualified electrician must determine the proper circuit breaker size to use for the power supplied to the system.

Overview

The system includes a vacuum transfer system that pulls the adhesive pellets into the system as needed. Once melted, the adhesive enters the pump where it is pumped into the heated hoses then to the heated applicators. The applicator then briefly opens to dispense the desired quantity of adhesive.

Even though the system rises to operating temperature quickly, there is a Schedule function in the ADM that eliminates waiting for the system to heat up. The Schedule function automatically enables the heating system at the user-specified times so the system is ready to dispense when a shift begins. The Schedule function also disables the heating system at user-specified times to ensure the heating system is disabled when not being used.

NOTE: Only 1/4 in. (6 mm) round hot melt adhesive pellets can be used in the InvisiPac system. PSA-type adhesive pellets will not work in the InvisiPac system.

1. Direct the applicator into an appropriate waste container.

2. Verify the shaker inlet is at the bottom of the empty adhesive pellets container. Optional vibrating adhesive pellets container, part 24R136, is available. See Accessories on page 100.

NOTE: The shaker inlet must be completely covered in adhesive pellets to effectively pull pellets into the tube.

3. Fill adhesive pellets container with hot melt adhesive pellets.

4. Turn main power switch ON .

5. Open system air inlet ball valve.

. 20.

NOTE: If using shaker accessory, regulator should be set to at least 65% of air pressure connected to shaker.

NOTE: Vacuum transfer will not begin operating until pump reaches operating temperature.

10. On new systems only: After the melter has reached

250°F (121°C) and the funnel is filled with pellets, set the melter temperature back to the desired operating temperature. See Select ADM Settings on page 24 for instructions.

11. Use separate pattern controller to open the applicators and keep them open.

NOTICE

In the following step, to prevent damage to the pump due to pump cavitation, do not supply more than 20 psi (140 kPa, 1.4 bar) air pressure to the pump until the system is fully primed.

12. With the applicators open and the system up to temperature, slowly increase pump air pressure until the pump begins to run very slowly. Approximately 20 psi (140 kPa, 1.4 bar) should be sufficient.

NOTE: Operation may be erratic below 20 psi (140 kPa,

1.4 bar).

13. Continue running the pump until clean, air-free material is dispensed from each applicator.

14. When each applicator is fully primed, adjust pump to desired pressure setting:

To prevent fire and explosion, never exceed the cleaning fluid’s rated temperature. If the system was just flushed, residual cleaning fluid is still in the system until the system is primed with adhesive. Do not raise temperature above cleaning fluid rated temperature until system is primed with adhesive.

NOTE: A new system may have residual oil due to testing at the factory prior to shipping. To prevent smoking, make sure to perform the following step.

8. On new systems only: temporarily adjust the melter

temperature to 250°F (121°C). See Select ADM Settings on page 24 for instructions.

9. Press to enable the heaters and pump.

NOTE: When system is up to temperature, the pump will be activated automatically, but will not start because there is no air pressure supplied to the pump.

NOTE: When the melter is up to temperature, the auto-fill function will initiate to fill the funnel with pellets.

a. Adjust pump pressure to between 20-100 psi

(140-690 kPa, 1.4-6.9 bar).

b. Use separate pattern controller to repeatedly

open and close each applicator while inspecting the dispense pattern.

c. Repeat until desired dispense pattern is

achieved.

Manual Refill

NOTE: Use Automatic Refill whenever possible. The

system uses Automatic Refill by default and must be manually changed to Manual Refill. Only use Manual Refill if the Automatic Refill system is not functioning properly and cannot be fixed in a timely manner. Perform service to automatic feed system as soon as possible to limit debris buildup on feed funnel.

Operation

It is recommended to maintain a minimum flow rate of

1.5 lb/hour to prevent material from melting within the feed cap and funnel. If production rate is below

1.5 lb/hour or system sits at temperature without dispensing for extended periods of time, use manual refilling with caution. System flow rate can be monitored by enabling the Diagnostic screen.

1. On the System 3 screen (in the Setup screens), select “Manual” from the Refill mode dropdown.

2. Remove the two bolts from the funnel bracket, then remove the top portion of the funnel.

5. Refill the funnel as needed to maintain the required dispense rate.

6. When finished dispensing for the day, dispense into a waste container until the material level is down to the melter core. See F

. 23.

NOTE: This will lower the adhesive level within the funnel cap to the correct level to prevent any issues upon startup the following production day.

Operation Tips to Minimize Charring

Set the Pump Idle Time to System Inactive function on the System 3 screen to lowest value that will not interfere with normal operation. This feature automatically disables the heating system if the pump is idle for longer than the preset amount of time. Disabling the heating system minimizes adhesive degradation and limits char formation.

When possible, utilize the Schedule function, see page 33, to automatically enable and disable the heating system in accordance with your production schedule. This will ensure adhesive spends as little time at temperature as possible. Less time at high temperature ultimately means less adhesive degradation and less

char.

Failure of the level sensor (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 operating 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 manual refill mode. See Manual Refill on page 30.

Some adhesives are very dusty due to the anti-blocking agents used or because the adhesive manufacturing process has created small adhesive

USB Log Full The InvisiPac system

will display this notification when the USB data logs reach 90% full.

The InvisiPac system is displaying pump runaway or pump diving.

This error generally occurs when the pump cavitates due to improper material loading.

To prevent data loss, download system data. See Appendix B - USB Downloading, Uploading on page 120.

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 temperature in small increments over the current set point.

3. If the pump continues to runaway or dive continue increasing temperature 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 following the Pressure Relief Procedure, page 33.

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 applicator temperatures of 350°F.

Level sensor blocked, reading level incorrect.

The system is not supplying enough air to the ultrasonic sensor venturi.

Clean feed cap by fill sensor, make sure there are no adhesive pellets blocking the sensor hole.

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 sensor 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).

Problem Cause Solution

Unable to achieve published melt rate at the desired adhesive temperature.

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 (11 cpm - HM25, 22 cpm - HM50) and the system is still running away increase the InvisiPac system temperature in small increments over the current set point, leave hoses and applicators at desired set point.

2. If the pump continues to runaway or dive continue increasing temperature in small increments. 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 the published melt rate. The InvisiPac system was tested to achieve continuous the published melt rates when dispensing standard EVA packaging grade adhesives in pellet form with an InvisiPac system temperature of 350°F and hose and applicator temperatures of 350°F.
