NOTICE

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

When software is updated on the DM, the software is then automatically updated on all connected GCA com ponents. A status screen is shown while the software is updating to indicate the progress. When the status bar is complete, press to continue.

The DM will display an error message when initialization is complete. This error occurs because the machine has not been calibrated. Press to acknowledge the error and continue with the setup procedure.

When the main electrical power is turned on, the splash screen will be displayed until communication and initial ization is complete.

Setup

1. Purge Material Lines.

d. Open the base (A) main air slider valve.

To avoid personal injury or machine damage, adjust all air regulators counter-clockwise prior to turning the main air on.

a. Load material.

Ram: Perform the “Change Drums” procedure in the Air-Powered Ram manual.

Pressure Pot: Perform “Filling the Tank” pro cedure in the 5-, 10-, and 15-Gallon Pressure

Tanks manual. An agitator is recommended for urethane applications utilizing a pressure pot.

Set the agitator to 25-50 rpm.

b.

Calibration Check Assembly Only: Close the calibration check assembly.

e. Set the base (A) air motor regulators to 10 psi

(70 kPa, 0.7 bar).

To avoid personal injury or machine damage, do not exceed 25 psi on the base (A) material until a steady flow of material has been established.

c. Close the base (A) air motor slider valve.

f. Set the fluid regulator adjustment to 40 psi

(280 kPa, 2.8 bar).

36 g. Place the base (A) hose end into a waste con tainer.

h. Activate on the DM.

l. Deactivate on the DM.

Setup i. Open the base (A) air motor slider valve.

m. Close the base (A) air motor slider valve.

j. Increase the base (A) air motor regulator as required to have material flow out of the hose.

n. Repeat steps a through m for the catalyst (B)

hose. Refer to

Integrated Air Controls , page 19, for visual clarity.

NOTE: Activate on the DM when prompted and all slider valves refer to the catalyst (B) air controls.

k. Dispense the material into the waste container until the base (A) material hose is purged and free of air.

cator.

MD2:

a. Connect both base (A) and catalyst (B) material hoses to the dispense applicator.

b. Activate both and on the DM.

Ultra-lite:

a. Connect the base (A) hose to the base (A) inlet fitting.

b. Connect the catalyst (B) hose to the catalyst (B) inlet fitting.

c. Open the catalyst (B) ball valve and dispense material into a waste container until the dis pense valve has been purged and is free of air.

d. Activate on the DM.

c. Open the catalyst (B) ball valve and dispense material into a waste container until the dis pense valve has been purged and is free of air.

d. Close the catalyst (B) ball valve and dispense material into a waste container until only base (A) is present.

bly.

a. Open the base (A) and catalyst (B) air motor slider valves.

Setup c. Place a waste container underneath the cali bration check assembly.

d. Remove the JIC caps from the calibration check assembly.

e. Open the calibration check assembly.

b. Activate both and on the DM.

3A2894U 39

Setup f. Dispense the material into the waste container until both the base (A) and catalyst (B) material lines have been purged and are free of air.

g. Close the calibration check assembly.

4. Calibrate the machine.

Perform the following procedure during initial setup of the machine, if the flow meters were replaced, or if the machine needs to be recalibrated.

a. Engage the trigger lock.

b. Open the base (A) and catalyst (B) air motor slider valves.

h. Clean the nozzles of the calibration check assembly and install the JIC caps.

i. Activate on the DM.

c. Set the base (A) and catalyst (B) air motor regu lators.

MD2 or Ultra-lite with flexible hose:

70 psi (480 kPa, 4.8 bar).

Ultra-lite with Tri-core :

85 psi (586 kPa, 5.9 bar)

40 3A2894U

d. Set the fluid regulator adjustment to 40 psi

(280 kPa, 2.8 bar).

Setup g. Activate to signal the machine of the fol lowing calibration shot.

h.

MD2: Install the calibration nozzle onto the dis pense applicator.

e. Place two separate containers on two separate scales and zero the scales. These containers

will be used in step j.

NOTE: Weight units of the scales are to be set as grams.

f. Navigate to setup Screen 2 .

NOTE: Screen 2 is already shown if this procedure is performed during the initial setup of the machine.

Screen 2 - Recalibration i. Disengage the trigger lock.

Screen 2 - Initial Calibration

Setup j. Dispense the chemicals into two separate con tainers.

MD2: Chemical will be dispensed through the applicator.

Ultra-lite: Chemical will be dispensed through the calibration check assembly.

l. Weigh both containers separately and input the values of both chemicals into setup Screen 2 .

NOTE: To change a value in a desired field, perform the following.

• Press or desired field to be changed.

to highlight the

• Press to activate the desired field or to activate/deactivate an option.

• Press or to change the value of the selected field.

• Press to set the value.

NOTE: Weight units are in grams.

k. Continue to dispense the chemical into the containers until both status bars are complete.

NOTE: If the light tower is installed, a green light will be illuminated when the status bars are complete.

m. Press to signal the machine that the cali bration procedure is complete. The machine will automatically calculate the K factor of both materials.

n. Engage the trigger lock.

o.

MD2: Remove the calibration nozzle and install a static mixer on the dispense valve.

p. Navigate to the

Home

screen.

5. Set the Display Module (DM).

Perform the following tasks to fully setup the DM. Refer
