Setup

Grounding

The equipment must be grounded to reduce the risk of electric shock. Improper grounding can cause electric shock. Grounding provides an escape wire for the electric current.

The InvisiPac system is equipped with a ground terminal. Have a qualified electrician ground the system using this terminal. See Connect Electrical Cord on page 19.

Location

Ambient temperature must be 32-120°F (0-49°C).

The supplied vacuum transfer hose length is 10 ft (3 m). The maximum vacuum transfer hose length available is 30 ft (9.1 m). The adhesive pellets container must be located within reach of the vacuum transfer hose and no more than 30 ft (9.1 m).

Attach Components

To reduce the risk of electric shock, do not connect electrical cord until after this Attach Components procedure is complete.

1. Place the base system in the desired operating

location and orientation. See Location on this page.

• The bottom of the electrical enclosure has holes for securing the InvisiPac system to a surface. The holes are accessible through the bottom access doors in the three rear walls of the electrical enclosure.

• To install the InvisiPac system in place of a

non-Graco hot melt system, purchase Adapter Plate, 24R083. See installation instructions on

page 91.

The gun(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 91.

If installing the system in place of a non-Graco hot melt system, purchase Adapter Plate, 24R083. See page 91.

Optional 30 Gallon Vibrating Hopper, 24R136, available (purchase separately). See page 92.

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

• To raise the system to eye-level, purchase System Stand, 24R088. See installation instructions on page 91.

NOTE: Supplied vacuum transfer hose must reach from the system to the adhesive pellets container. Supplied heated hose must reach from system to gun(s).

2. Install vacuum transfer inlet funnel (G3) onto system. See F

a. Slide funnel through the bracket connected to

the air motor.

Setup

480V Electrical Circuits

For 480V electrical supply, a 480V to 240V step-down transformer must be installed by a qualified electrician.

Transformer Sizing

For single-phase power, 480V to 240V transformer 24U169 (purchase separately) may be used. See Sin- gle-Phase 480V to 240V Transformer, 24U169 on page 100.

Minimum transformer rating can be calculated by taking 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

√

(3) = 8315 watts

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.

3. On the System 2 screen:

a. Check the box in the “Installed” column for each

channel that has a heated hose and gun installed.

b. Select the RTD type used on each installed

gun. See gun manual.

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.

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

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

4. On the System 3 screen:

3A2347T 21

a. Enter the main circuit breaker size used. This is

the circuit breaker installed external to the system for the system power supply.

Setup

NOTE: If using a 480V to 240V transformer, the breaker size entered will be two times the 480V rating. If using transformer 24U169, the breaker size should be set to 30 amps and power type should be set to single phase.

NOTE: The InvisiPac system limits the amount of power it pulls based on the input circuit breaker size. This impacts the startup times because it affects the heating energy used to warm up the materials.

b. Select the incoming power type.

to adjust heated hose temperature setting to the desired setting for that channel.

NOTE: Alternatively, use the physical up and down

arrow push-buttons on the ADM keypad until is next to the temperature setting to change then use the

numeric keypad to enter the desired temperature.

NOTICE

Set melter, hose, and gun to the same setpoint temperature for best performance. Do not set the hose temperature higher than the melter. Running the hose at a setpoint higher than the melter is unnecessary in this tank-free system and could lead to adhesive degradation in the hose. Short adhesive residence time in the melter eliminates the need to set the melter at a lower setpoint than other zones. See Operation Tips

to Minimize Charring, page 33.

NOTE: Alternatively, use the physical up and down

arrow push-buttons on the ADM keypad until is next to the temperature setting to change then use the numeric keypad to enter the desired temperature.

Operation

Heating and dispensing hot melt adhesive may create potentially harmful vapors. Read material manufacturer’s warnings and material MSDS to know specific hazards and precautions. Ventilation of the work area may be required.

NOTE: See Appendix A - ADM on page 104 for detailed ADM information.

NOTICE

To prevent damage to soft key buttons, do not press the buttons with sharp objects such as pens, plastic cards, or fingernails.

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 guns 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 89.

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.

NOTE: See Appendix B - USB Downloading, Uploading on page 110 for detailed USB information.

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 guns. The gun 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.

4. Turn main power switch ON .

5. Open system air inlet ball valve.

WLE

6. Use pump air pressure regulator (C) to adjust pump air pressure to 0. See F

7. Use vacuum transfer air pressure regulator (E) to adjust vacuum transfer air pressure setting to 40-100 psi (280-690 kPa, 2.8-6.9 bar). Recommended setting is 60 psi (414 kPa, 4.1 bar). See

. 1 on page 8.

Initial Startup and Prime

NOTE: All setup procedures must be completed prior to initial startup. See Setup on page 14.

26 3A2347T

Operation

FIG. 1 on page 8.

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

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 21 for instructions.

9. Press to enable the heaters and pump.

12. With the guns 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 gun.

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

a. Adjust pump pressure to between 20-100 psi

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

b. Use separate gun controller to repeatedly open

and close each gun while inspecting the dispense pattern.

c. Repeat until desired dispense pattern is

achieved.

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.

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 21 for instructions.

11. Use separate gun controller to open the guns 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.

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 cap.

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 phillips head screws then remove the funnel cap from the funnel.

3A2347T 27

3. Fill the funnel with adhesive pellets.

ti21154a

FIG. 19

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

5. When finished dispensing for the day, dispense into a waste container until the material level is down to the smallest diameter section of the funnel then continue purging material through the valve for an additional 75 pump strokes.

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

Automatic Refill

The system uses automatic refill by default. If the automatic refill system is malfunctioning and cannot immediately be fixed, Manual Refill can be used.

To use automatic refill:

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

2. Verify shaker and tube are connected to the system. See Attach Components on page 14.

3. Verify shaker inlet (K) is at the bottom of the adhesive pellets container that is filled with hot melt adhesive pellets. See F

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

4. If not already set, use vacuum transfer air pressure regulator (E) to adjust vacuum transfer air pressure setting to 40-100 psi (280-690 kPa, 2.8-6.9 bar). Recommended setting is 60 psi (414 kPa, 4.1 bar). See F

. 1 on page 8.

NOTE: The system will automatically transfer the pellets to the system as necessary.

. 1 on page 8.

NOTE: Pump strokes can be monitored on the Maintenance screen, or by counting pump changeovers. To count pump changeovers, listen to the air motor exhaust pulses; two exhaust pulses equals one pump cycle (two strokes).
