6.8.3.3 Fluid Pressure Regulator and Gauge

The Fluid Pressure Regulator controls the pressure of the fluid reservoir for the SC-205 Non-Circulating

Film Coater and the SC-200 Slim Swirl Applicator. For the SC-105HS High Speed Film Coater, this

regulator controls the pilot pressure to the pilot operated fluid regulator on the rear of the dispensing

system. For more details on how the air is used for fluid pump operation and recommended pressure

setting, refer to the manual for your specific fluid pump.

To adjust the fluid pressure:

1. Verify the Reservoir Air Pressure Pneumatic Switch (

Figure 6-9) is in the ON (l) position.

2. Locate the Fluid Pressure Regulator adjustment knob underneath the left side of the

front hood.

3. Unlock the knob by pulling it downward.

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

increase to the desired pressure.

4. Rotate the Fluid Pressure Regulator adjustment knob counterclockwise until the Fluid

Pressure Gauge registers 0 psi.

5. Rotate the knob clockwise until the Fluid Pressure Gauge registers 60 psi (413 kPa).

6. Monitor the Fluid Pressure Gauge to make sure that pressure builds at a steady rate. Watch

for dropping pressure indicating an air leak.

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

before proceeding.

7. Lock the knob by pushing it upward.
