To check the function of the Valve Air Pressure Regulator and Digital Gauge:
1. Locate the Valve Air Pressure Regulator inside the front cabinet of the dispensing system
(Figure 4-9).
2. Verify the LED display screen on the front panel is illuminated.
If the LED is not working, check electrical connections. If still not working, contact
Asymtek Technical Support.
3. Initialize the gauge as specified in
4. After the digital gauge has been initialized, shut off air pressure by turning the Valve Air
Pressure Regulator counterclockwise. Make sure the gauge settles at 0 psi.
5. Increase air pressure to 90 psi (621 kPa) by turning the Valve Air Pressure Regulator
clockwise.
Valve air pressure may vary depending on dispensing valve used.
6. Monitor the gauge display to make sure that the 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.
If the gauge is not working properly, contact Asymtek Technical Support.
To check the function of the Fluid Air Pressure Regulator and Digital Gauge:
1. Locate the Fluid Air Pressure Regulator inside the front cabinet of the dispensing system
(Figure 4-9).
2. Verify the LED display screen on the front panel is illuminated.
If the LED is not working, check electrical connections. If still not working, contact
Asymtek Technical Support.
3. Initialize the gauge as specified in
4. After the Fluid Digital Gauge has been initialized, shut off air pressure by turning the Fluid
Air Pressure Regulator counterclockwise. Make sure the gauge settles at 0 psi.
5. Increase air pressure to 30 to 40 psi (206 to 275 kPa) by turning the Fluid Air Pressure
Regulator clockwise.
6. Monitor the gauge display to make sure that the 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.
If the gauge is not working properly, contact Asymtek Technical Support.
