Pneumatic Regulators and Gauges
Perform the following procedures to check the function of the Pneumatic Regulators and Gauges.
To check function of Main Air Pressure Regulator and Gauge:
1. Locate the Main Air Pressure Regulator at the rear of the dispensing system. See Figure 5-5.
2. Unlock the Regulator Knob by pulling it upward and increase the air pressure to 80 psi
(551 kPa) by turning the knob clockwise.
3. Monitor the Main Air Pressure Gauge to make sure that pressure builds at a steady rate.
Listen for any air leaks as the pressure builds.
> If there is an air leak, identify the source, shut off the facility air, and fix the leak
before proceeding.
4. Bleed the air pressure to 0 psi by turning the Regulator Knob counterclockwise. Verify the
Main Air Pressure Gauge settles at 0 psi.
5. Turn the Regulator Knob clockwise to increase the air pressure to 80 psi (551 kPa). Lock the
knob by pushing it downward.
To check function of Valve and Tooling Air Pressure Regulators and Gauges:
1. Locate the Valve and Tooling Air Pressure Regulators and Gauges inside the Front Cabinet
of the dispensing system. See Figure 5-5.
2. Bleed air pressure until the Gauges read 0 psi. Make sure both Gauges settle at 0 psi.
3. One Regulator at a time, increase air pressure to the following settings:
Valve Air: 70 psi (482 kPa)
Tooling Air: 40 psi (275 kPa)
4. Monitor the Gauges to make sure that pressures build at a steady rate. Listen for any air leaks
as the pressure builds.
> If there is an air leak, identify the source, shut off the facility air, and fix the leak before
proceeding.
To check function of Fluid Air Pressure Regulators and Digital Gauges:
1. Locate the Valve 1 Fluid Air Pressure Regulator and Gauge inside the Front Cabinet of the
dispensing system. See Figure 5-5.
2. Verify the LED display screen on the Gauge is illuminated.
> If the LED is not working, check electrical connections. If still not working, contact
Asymtek Technical Support.
3. Perform Valve 1 Digital Gauge initialization as specified in the Calibration and Adjustment
section of this manual.
