5.9 Calibrating the E/P Controllers

If the dispensing system is configured with the optional electronic pressure control utility, follow the

procedure below to calibrate the E/P controllers. During the calibration process, you will ensure that the

Fluidmove pressure set point and Fluidmove pressure reading matches the external pressure gauge

reading.

 NOTE This procedure assumes that the dispensing system is ON and Fluidmove is running.

Tools and Materials Needed:

• External Pressure Gauge

• Quick Disconnect Fitting

To calibrate the Fluidmove set point with the external gauge reading:

1. In the Fluidmove Main Window, select

Configuration > Setup Runtime Preferences >

Local Machine Offsets

.

 The Local Machine Offsets window opens.

2. Select the Air Pressure tab (Figure 5-15).

 This tab displays the Set Point, Set Point Offset, Reading Offset and Reading for

cooling, valve, and fluid pressure. The value in the “Reading” column is the same as the

value in the Current Pressure window (Figure 5-17) accessed by pressing [Ctrl + P] on

the dispensing system keyboard.

Figure 5-15 Local Machine Offsets - Air Pressure Tab

3. To establish air pressure set points, click on the numbers in blue, enter the desired values

and press enter. Click on

OK.

 It is best to calibrate valve air pressure with the same pressure setting that will be used

in the dispensing program. It is not necessary for cooling and fluid pressure adjustment.

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).

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 Adjusting the Air Pressure

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.
