4. Connect the external pressure gauge to the desired connection

(valve, fluid, or cooling) on the dispensing system bulkhead

(Figure 5-16) using a quick disconnect fitting.

 For the valve pressure reading, insert the external pressure

gauge hose into the black Valve 1 Off connection on the

bulkhead. If there is no reading, connect the hose to the

blue Valve 1 ON connection.

 You should now have a reading at the digital gauge.

5. Compare the external gauge pressure reading to the set point

displayed on the Air Pressure tab (Figure 5-15).

Figure 5-16 Dispensing

System Bulkhead

6. If the pressure reading on the external pressure gauge does not match the software set

point, click on the value in the "Set Point Offset" column and enter the difference between

the actual output (reading on the external gauge) and the set point on the Air Pressure tab.

Click on

Apply. A positive value will increase the output, and negative value will lower

the output. For example, if the gauge reading is 80.2 and the software set point is 80.0,

enter -0.2 in the “Set Point Offset” column. The external gauge output should now be 80.0.

 After the set point has been calibrated, it is necessary to calibrate the external pressure

gauge to the software reading.

To calibrate the Fluidmove current pressure reading to the external gauge reading:

1. Press [Ctrl + P] on the dispensing system keyboard to open the Current Pressure window

(Figure 5-17).

 The current pressure is the same as the pressure shown in the “Reading” column on the

Air Pressure tab in the Local Machine Offsets window (Figure 5-15).

Figure 5-17 Current Pressure Window

2. If the reading on the external gauge does not match the current pressure reading in the

software, click on the value in the “Reading Offset” column (Figure 5-15) and enter the

difference between the actual output (reading on the digital gauge) and the reading on the

Air Pressure tab. Click on

Apply.

 A positive value will increase the reading, and negative value will lower the reading.

For example, if the gauge reading is 80.0 and the software reading is 75.0, enter 5.0 in

the Reading Offset column. The software reading will change to 80.0.

3. When all applicable outputs have been calibrated, click

OK in the Local Machine Offsets

Window. The values are now set and the E/P controllers are calibrated.

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).

5.10.1 Air Regulators and Gauges

Air pressure is set manually at the regulator or in the Fluidmove software if the E/P (electronically controlled

pneumatic) regulators option is installed.

Refer to the Fluidmove User Guide or Fluidmove Online Help for

instructions on using the E/P option.

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.
