Initiate Connection

The 7040 can be operated by
applying a 5 to 24 VDC pulse to
terminal pins 1 and 2, or providing
contact closure across pins 5 and

7. Alternatively, a foot pedal may

be ordered (#2015A) and plugged
into the connector located on the
rear panel.

➃

Air Input Connection

1. Connect the controller to plant air
by first installing the five micron
filter regulator (#2000F755) to
the plant air supply.

2. Install the air tee with barb fit­ting (#1116 supplied with EFD
tank reservoirs) in the output of
the filter regulator, and install the
black hose with coupling to the
barb fitting. The quick-connect
on the air tee is used to provide
air pressure to the air pressure
regulator on EFD tank reser­voirs. This connection will be
made during valve installation.

3. Remove the cap plug from the air
input of the controller and attach
the input air hose coupling onto
the controller air-input fitting.

4. Set the pressure at the filter
regulator to 70 psi (4.8 bar).

7 / Adjusting the Spray

Adjusting the Spray

1. Turn the nozzle air pressure on the
controller to zero. Using the nee­dle stroke control knob ➀ on the
781S valve, set the fluid flow rate
to one or two drops per second.
Check flow rate by actuating the
controller in the time override
mode. Make valve stroke adjust­ments when the controller is off.

2. Set the nozzle air pressure on the
controller to 10 psi (0.7 bar) and
actuate the controller. The valve
will produce a fine spray.

3. To change fluid flow, use the
needle stroke control knob ➀,
and/or tank air pressure.

Note: Avoid tight stroke settings with high

tank pressure.

4. To change nozzle air, use the nozzle
air pressure regulator ➁. Higher
pressures will provide finer spray.

To Make Timed Deposits

1. Return to the time control by press­ing the time override button ➂. The
display should show the time setting.

2. Adjust the deposit time to 0.5 sec­onds by using the time set ➃ and
decimal ➄ buttons.

3. Press the cycle button ➅. The con­troller will open the valve for 0.5 sec­onds. Adjust time and test deposits
until desired output is obtained.

Note: Optimal results will be obtained

with the proper combination of time
setting, needle stroke control knob,
and reservoir and nozzle air pressure.

8 / Programming Nozzle Air Delay

Nozzle air delay is the time the nozzle air continues to
spray after the fluid is turned off. When spot marking
with low viscosity fluids, the delay can be reduced to
prevent blowing out the center of the mark. The delay
can be increased with high viscosity fluids and greases
to provide a spreading out effect.

1. Turn the power switch off.

2. Press and hold the time override button while
turning power switch on.

3. The display will read “SEL” (select). Release the
time override button.

4. Press either the up or down time set buttons once
and release. The current nozzle air-delay setting will
be displayed. (The delay is preset to 0.24 seconds
for all new controllers.)

5. Press the up or down time set button again to pro­gram the new nozzle air delay. (Available range is

0.00 to 2.50 seconds.)

6. To exit the nozzle air-delay program mode, momen­tarily press the time override button. The spray time
setting will be displayed.

Note: The controller will not operate while in the nozzle air

delay program mode.

If trouble cannot be corrected, or if you need further assistance,

please call us

.
In the US, call 800-556-3484. In the UK, phone [phone].
In Asia, [phone].

Trouble Possible cause and correction

Be sure that there is power at the wall
receptacle. Check the input power fuse.
If the fuse has blown, check the voltage
value in the fuse cartridge window. Be
sure that it matches the input voltage.

Ensure that the external voltage to the
circuit is between 5 and 24 VDC and that
the load does not exceed 250mA. If the
circuit has been overloaded, the fuse may
have blown. Replace fuse, if necessary.

Response delay in pneumatic circuit does
not allow the valve to open when time is
at or below 0.015 seconds. Increase time.

Valve operating pressure lower than 60 psi
(4.1 bar) can cause inconsistent output.
Make sure pressure is set at 70 psi (4.8 bar).

Check controller and reservoir air pres­sure readings to be sure air pressure is
not varying.

Air bubbles in the material can cause
inconsistency. For best results, remove all
air bubbles.

Check to be sure time override mode is off.

I/O Connection
The 9-pin D connector
and internal circuitry pro­vide external initiate and
end-of-cycle feedback
signal. The pin connec­tions are shown below.

Input/Output Connections

1. Voltage Initiate Circuit

The controller may be initiated with
a 5 to 24 VDC signal across pins
1 and 2. The signal can be momen­tary (no less than 0.02 seconds) or
maintained. A new cycle will begin
once power is removed and then
applied again.

2. End-of-Cycle Feedback Circuit

Upon completion of a dispense
cycle, an open collector circuit
closes and remains closed until the
next dispense cycle. This circuit
can be utilized to signal back to a
host computer, start another device
in sequence or other operations
that need to be tied into comple­tion of the dispense cycle.

Upon closure, power from an exter­nal 5 to 24 VDC source is allowed
to pass through the circuit to oper­ate a load. The load illustrated is a
relay, but this could be any device
that will operate within the 5 to 24
volt range. Power consumption of
the load must not exceed 250mA.

3. Mechanical Contact Initiate

The controller can be initiated via
the closure of mechanical con­tacts such as a relay or switch
using pins 5 and 7. Closure of
the contacts can be momentary
(no less than 0.02 seconds) or
maintained. A new cycle will
begin once the contacts are
opened and then closed again.

Note: For applications using more than

one 7040, see page 15 for connection
instructions.

1. Parallel circuit diagram for Voltage Initiate.

1. Voltage Initiate Circuit

To start the dispense cycle for multi­ple 7040 controllers at the same time,
connect the voltage initiate circuit in
parallel as illustrated.

Note: The amperage consumption for the

voltage initiate circuit will increase
with each controller that is connected.
The initiate power supply should be
sized accordingly.

2. End-of-Cycle Feedback Circuit

This circuit will ensure that the end­of-cycle signal will come from the last
7040 to complete a dispense cycle.
Connect in series as illustrated.

Note: There will be a maximum voltage

drop of 2.0 VDC through the feed­back circuit with each 7040 that is
added to the series. The input power
should be adjusted for this drop to
ensure that the required voltage is
available to operate the load.
Maximum input voltage to terminals
3 and 4 must not exceed 30.0 VDC.
