NOTE If the fluid pressure does register on the digital gauge, you must manually
enable the fluid pressure output by selecting
Tools>Dispenser from the
Fluidmove Main Window and toggling the Valve 1 Fluid Air (V1_Fluid_Air)
(Figure 5-18).

5.10.2 Adjusting the Tooling Air Pressure
The tooling air pressure regulates air supplied to the stop pins and lift tables. The regulator receives air
from the main air regulator located on the back of the dispensing system.
To adjust the tooling air pressure (Figure 5-19):
1. Locate the tooling air pressure regulator adjustment knob in the front cabinet.
2. Rotate the adjustment knob counterclockwise until the gauge registers 0 psi.
3. Rotate the adjustment knob clockwise until the associated gauge registers the air pressure
value (kPa or psi) required by your dispensing application.
For accurate pressure adjustment, lower the pressure below the desired level and then
increase to the desired pressure.
NOTE Pressure settings depend on the fluid being dispensed and dispensing valve
being used. Refer to the applicable dispensing valve manual for additional
information.
4. Monitor the tooling pressure gauge to make sure that pressure builds at a steady rate. A drop
in air pressure can indicate an air leak.
If there is an air leak, identify the source, shut off the facility air, and fix the leak before
proceeding.

5.10.3 Adjusting the Cooling/Coaxial, Valve, and Fluid Air Pressure
To adjust the cooling/coaxial, valve, and fluid air pressure (Figure 5-20):
1. Locate the desired air pressure regulator adjustment knobs in the front cabinet.
2. Rotate the adjustment knob counterclockwise until the gauge registers 0 psi.
3. Rotate the adjustment knob clockwise until the associated gauge registers the air pressure
value (kPa or psi) required by your dispensing application.
For accurate pressure adjustment, lower the pressure below the desired level and then
increase to the desired pressure.
NOTE Pressure settings depend on the fluid being dispensed and dispensing valve
being used. Refer to the applicable dispensing valve manual for additional
information.
4. Monitor the pressure gauge to make sure that pressure builds at a steady rate. A drop in air
pressure can indicate an air leak.
