or the inputs to the color change valves before priming the pump and filling the entire system.

1.

If using an electrostatic gun, shut off the electrostatics before filling the lines.

2.

Adjust the main air pressure. To ensure proper operation, set the main air pressure as close to

100 psi (0.7 MPa, 7.0 bar) as possible. Do not use less than 85 psi (0.6 MPa, 6.0 bar).

3.

If this is the first time starting up the system, or if lines may contain air, purge as instructed under

Flush the System, page 20

. The equipment was tested with lightweight oil, which should be flushed out to avoid contaminating your material.

4.

If on the ADM to bring up the Pump Power pop-up screen and, using the softkeys, turn on power to a specific Mix Unit or both. Make sure that the system is in Standby mode.

5.

Verify that the recipes and the flush sequences are programmed correctly by checking the

Recipe Screen, page 75

, and the

Flush Screen, page 78

.

6.

Enable the manual override on System Screen 1.

Select the desired color to load. Press the Prime

Pump key . The color will load the pump through the color stack and out the outlet stack dump valve.

9.

Press the Fill Line key to run color out to the remote mix manifold. The pump will run until you press the Stop key to stop the pump.

have color change valves and only a single material.

If a pump is filled with a material when the system is powered down, this will allow the user to change the pump’s contents, without flushing the pump, the next time power is restored.

1.

Enable the manual override on

System Screen 1, page 67

2.

Go to the

Fill Screen, page 64

3.

Press the Pre-Fill Pump key . The pump will change from material 61 to the proper color or catalyst.

To spray in a multiple color system, also see

Multiple Color Systems, page 97

.

, for further screen information, if needed.

1.

Command a Mix Unit to Mix. The system will load the correct mixed material volume.

Fill if the recipe is not currently loaded into the system. The Mix Fill volume calculation includes the remote mix manifold volume and the mixed material hose volume. The mixed material hose volume is determined by the gun hose length and diameter entered in

System Screen 3, page 69

, and the remote-to-mix hose length and diameter also entered in

System Screen 3, page 69 .

2.

Adjust the flow rate by changing the target pressure (in Pressure Mode) or the target flow rate (in Flow Mode) on the Spray Screen or through the PLC. The fluid flow rate shown on the

Spray screen is the combined total of component

A and B out of the spray device.

3.

Turn on atomizing air to the spray device. Check the spray pattern as instructed in your spray device manual.

Do not allow a fluid supply tank to run empty.

This can damage the pumps and lead to the proportioning of fluid and air that meets the ratio and tolerance settings of the equipment. This can further result in spraying uncatalyzed or poorly catalyzed material.

To purge one color and fill with a new color, see

Color Change, page 97

.

To avoid fire and explosion, always ground equipment and waste container. To avoid static sparking and injury from splashing, always flush at the lowest possible pressure.

There are times when you only want to purge the remote mix manifold and the spray device, such as:

• end of potlife

• breaks in spraying that exceed the potlife

• overnight shutdown or end of shift

• before servicing the remote mix manifold, hose or gun.

1.

Command the Mix Unit to Standby.

2.

If you are using a high pressure spray device or an electrostatic gun, shut off the atomizing air.

3.

To reduce the risk fire and explosion, shut off electrostatics before flushing the gun.

If using an electrostatic gun, shut off the electrostatics before flushing the gun.

4.

Command the Mix Unit to Purge A,

Purge B, or Recipe Purge. (See

Purge Mode Sequence, page 41

.) Trigger the spray device into a grounded metal pail until the purge sequence is complete. When done purging, the Mix Unit automatically switches to

Standby mode, signalling the spray device to stop spraying.

of solvent after purging.

To avoid fire and explosion, always ground equipment and waste container. To avoid static sparking and injury from splashing, always flush at the lowest possible pressure.

Follow this procedure before:

• the first time material is loaded into the equipment

• servicing

• shutting down equipment for an extended period of time

• putting equipment into storage

1.

Relieve the pressure.

See

Pressure Relief Procedure, page 18 .

2.

Disconnect the color and catalyst supply lines from the pump inlet manifolds, and connect regulated solvent supply lines.

3.

Set the solvent supply pressure regulator at the lowest pressure possible. Generally a setting of 25–50 psi (0.18–0.35 MPa, 1.8–3.5 bar) is sufficient.

4.

Enable manual override on

System Screen 1, page 67

5.

On the ADM, go to the Fill screen for Mix Unit

#1. Set the Material to Color (A). Press .

The system will pump solvent through pump A all the way to the gun.

6.

Hold a metal part of the spray device firmly to a grounded metal pail. Trigger the spray device until clean solvent dispenses.

7.

On the ADM, go to the Fill screen for Mix Unit

#1. Set the Material to Catalyst (B). Press

The system will pump solvent through pump B all the way to the gun.

Relieve the pressure.

See

Pressure Relief Procedure, page 18 .

2.

Attach regulated solvent supply lines as follows: color side, do not disconnect the color supply line from the inlet manifold of Pump A. Instead, connect a regulated solvent supply line to the designated solvent valve on the color valve manifold. On the catalyst side, disconnect the catalyst supply line from the inlet manifold of Pump B, and connect a regulated solvent supply line.

Connect regulated solvent supply lines to the designated solvent valves on the color and catalyst valve manifolds. Do not connect solvent supply lines directly to the inlet manifolds of the pumps.

3.

Set the solvent supply pressure regulator at the lowest pressure possible. Generally a setting of 25–50 psi (0.18–0.35 MPa, 1.8–3.5 bar) is sufficient.

4.

On the ADM, go to the Fill screen for Mix Unit

#1. Select Color (A). Enter the color number in the box to the right.

5.

Select the Flush Line box.

6.

If the solvent is not already loaded, press the

Prime softkey . The Mix Unit will prime solvent into the selected pump and out the outlet dump valve.

7.

Press the Fill softkey . The Mix Unit will flush the selected Color (A) line with the solvent until the user presses Stop .
