Loading Material into PrecisionFlo Module
The PrecisionFlo module compensates for tempera-
ture, flow, or pressure fluctuations, but if you change
hardware on the dispensing system or change types of
material, reconfigure the PrecisionFlo module’s soft-
ware. Before you can configure the software for your
application, you must load material into the supply
system.
NOTE: Some of the software settings are password
protected. To obtain the password, contact your Graco
service representative.

Material Loading Procedure
WARNING
COMPONENT RUPTURE HAZARD
Never exceed the maximum air or fluid
working pressure rating of the lowest
rated component in the system. Over-
pressurization can cause component
rupture and serious bodily injury.
To help reduce the risk of injury or
equipment damage, do not pressurize
the system until you have verified the
system is ready and it is safe to do so.
To reduce risk of injury or damage to
equipment, make sure all material hose
connections are secure.
NOTE: Read this procedure before powering up the
module.
1.
Make sure you have installed and made all the
proper connections to and from the PrecisionFlo
control assembly enclosure.
2.
Turn ON electrical power to the control assembly.
3.
Set pressure sensor characteristics:
h.
Set scale factor for pressure sensors (page 19).
i.
Set sensor pressure limits using the proce-
dures beginning on page 20.
4.
Set nominal values for Kp and Kd. You need to
adjust Kp and Kd so the system can begin dis-
pensing material. For more information, see
page 21.
5.
Turn on fluid supply pressure to the module.
6.
Place the dispense device over a waste container.
7.
Disconnect the flow meter from the control assem-
bly.
8.
Calibrate the PrecisionFlo module in pressure
mode at 1500 psi so you can dispense fluid in
step 9. See page 21 for more information.
9.
Use the pendant to place the module in MANUAL
mode and set it for 80% of full output. For more
information about manual mode, see page 22.
10. Manually dispense fluid until clean, air-free fluid
flows from the dispense device.
11. To configure the software, go to the Configuring
the PrecisionFlo Module section on page 23.
