Final Setup Checklist

 Air pressure to solenoid pack is set to 5.5bar (80psi).

 Nozzle air pressure regulator is set to 1.02bar

(10psi).

 Solenoids and I/O are wired correctly.

 Spray valves and ﬂuid reservoir are properly

connected.

 Spray valves are set up and installed in accordance

with the spray valve installation guide.

 Turn power on. Conﬁrm indicator lamps and display

is lit.

NOTE: The ValveMate 8040 is not equipped with an

ON / Off switch and remains in ON condition as long as

input power supply voltage is maintained.

ValveMate 8040 Controller

Set tank pressure. For low viscosity, low pressures and

high viscosity, higher pressure.

Using the MODE button on the ValveMate controller,

place the controller in the PURGE mode. In

PURGE mode only, channels ···· and ····

can be selected independently without nozzle air

pressure.

Using the SEL button, press to sequence as follows:

Place a container under the spray valve and press the

CYCLE button to open the spray valve and ﬂow

material until all air is purged from the system. Adjust

the tank pressure, or valve stroke knob to set a ﬂow

rate that is not too low or too high. A goal starting point

for a ﬁne spray is one drop of ﬂuid per second. For

heavier spray, increase the drop rate just below where

the ﬂow becomes a steady stream. Adjust ﬂow using a

combination of tank pressure and valve needle stroke.

Testing the Spray Valves

Set nozzle air pressure regulator to 0.7bar (10psi).

Using the PURGE mode again, actuate the spray

valves and observe the spray sequence: ····

Press SEL: Channels

Press SEL: All channels are now active.

Press mode and place controller in SETUP mode.

Using the UP / DOWN buttons, set a spray time

of 0.05 seconds for all valves.

Press the CYCLE button to initiate a spray cycle.

Increase or decrease the time or tank pressure to arrive

at the desired deposit size. The primary control of

deposit size is the valve open time. Final time setting

may be different for each valve as this is the way we

compensate for minor variations in tubing length or

tolerance stack up.

The system is now ready to be initiated by the machine

controls when the machine is started.
