4-12 Power-up and Testing

To check the function of the Conveyor Air Regulator and Gauge:

1. Locate the Conveyor Air Regulator adjustment knob inside the rear cover of the coating

system (Figure 4-9).

2. With the Main Air Pressure ON, check the gauge reading. It should read 40 psi (± 5 psi).

3. If the Conveyor Air Regulator needs adjustment, loosen the jam nut to unlock the regulator.

4. Rotate the regulator counterclockwise until the Conveyor Air Gauge registers 0 psi.

5. Rotate it clockwise until the Conveyor Air Gauge registers 40 psi (276 kPa).

6. When the desired air pressure is set, tighten the jam nut on the Conveyor Air Regulator.

To check the function of the Electronics/Pressure Regulator and Gauge

Electro pneumatic regulators control the pilot pressure to the fluid regulator. Pressure is adjusted and

monitored through the ECXP software. See 5.10.3 Fluid Pressure Regulator and Gauge.

 NOTE If your coating system is equipped with two fluid systems, there will be two

Electronics/Pressure Regulator and Gauge sets.

4-14 Power-up and Testing

To check the function of the Reservoir Pressure Regulator and Gauge:

1. Locate the Reservoir Pressure Regulator adjustment knob inside the front cabinet.

2. Unlock the knob by pulling it outward.

3. Rotate the Reservoir Pressure Regulator adjustment knob counterclockwise until the

Reservoir Pressure Gauge registers 0 psi.

4. Rotate the knob clockwise until the Reservoir Pressure Gauge registers 60 psi (413 kPa).

TIP For accurate pressure adjustment, lower the pressure below the desired level and then

increase to the desired pressure.

 If there is an air leak, identify the source, shut off the facility air, and fix the leak before

proceeding.

5. Lock the knob by pushing it inward.
