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: Channel  only is active  is off.

Press SEL: Channels

···· only are active.

Press SEL: Channel

 only is active  is off.

Press SEL: Channels

···· only are active.

Press SEL: Channels

 and  only.

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.

Part Numbers

NOTES:

• Power cords are ordered separately.

• Solenoids are ordered separately based on the number of valves in the system. Each solenoid kit includes the

prewired 6-pin connector and housing, a 3.6 m (12 ft) cable cordset, an input air hose, and push-in ﬁttings.

Troubleshooting

Problem Possible Cause and Correction

LED is blinking “ALr”

and

will not accept initiate signal.

Air pressure to the solenoid pack has

dropped below 4.1bar (60psi) or if low level

ﬂoat switch is used, tank level is low. Raise

the input pressure to 4.8bar (70psi) or reﬁll

the tank. Press CYCLE

button to reset.

If problem persists, make sure devices such

as air cylinders are not causing a pressure

drop in the ValveMate 8040 solenoid pack

input air line. If no ALARM switch is being

used, the ALARM IN + / - terminals must have

a jumper installed to disable ALARM feature.

Unit is not responding to the

initiate signal.

Check to make sure the unit is not in a mode

other than RUN

. Response delay in

pneumatic circuit does not allow the valve to

open when time is set at or below 0.010

seconds. Increase time. Initiate signal may

have a low level of leakage. The signal must

break clean before the next signal is initiated.

Timer is inoperative. Check to make sure the unit is not in the

steady mode. The timer is very reliable. Any

failure is total so no inconsistency is possible.

Flashing

on LED display.

Short on the OUT TO SOLENOID circuit.

Check solenoid wiring connections.
