• The 7000 features a low pressure alarm
system. An output signal, in the form of a
solid-state switch, closes when pressure
drops below 60 psi (4.1 bar). This closure
can be used to operate an audible alarm,
shut-off switch or other device. Maximum
load is 250mA from 5 to 24 VDC. In
addition, when the air pressure is low,
the display will flash between “air” and
“pressure” indicating that pressure has
dropped below minimum. (See page 4
for instructions on deactivating or reactivating the alarm.)
• An End-of-Cycle signal, also in the form of
a solid-state switch, closes upon completion of the dispense cycle. Maximum load
is 250mA from 5 to 24 VDC source (not
included).
• The 7000 can be initiated using a 5 to 24
VDC signal.
• The 7000 can also be initiated with a
contact closure such as a mechanical
relay or optional foot pedal (order separately #2015A).

13 / Troubleshooting
There is an “AIR”message.
No power.
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 0800 585733.
In Asia, +86 (21) 5854 2345.
Trouble Possible cause and correction
The low level air alarm is active. Raise the
input pressure to 70 psi (4.8 bar) on the
display. Press
RUN / SETUP
button to reset.
Air pressure has momentarily dropped
below 60 psi (4.1 bar). Increase input air
pressure to 70 psi (4.8 bar). If already at
70 psi (4.8 bar), check to make sure that
other devices such as air cylinders are not
causing a pressure drop in the ValveMate
7000 input air line.
Check the input power fuse. If the fuse
has failed, 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 be open. See internal diagram
on page 15 and replace fuse if necessary.
Response delay in pneumatic circuit does
not allow the valve to open when time is set
at or below 0.010 seconds. Increase time.
Check to make sure unit is not in
STEADY
mode. The timer is very reliable. Any failure
is total, so no inconsistency is possible.
End-of-Cycle Feedback
Circuit or low pressure alarm
is not functioning.
Does not dispense below
0.010 second time setting.
1. Voltage Initiate Circuit
The ValveMate 7000 may be initiated with a 5 to 24 VDC
signal. The signal can be momentary (no less than 0.008
seconds) or maintained. A new cycle will begin once
power is removed and then applied again. Refer to the
schematic for proper installation.
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 the completion of
the dispense cycle.
Upon closure, power from an external source is allowed
to pass through the circuit to operate a 5 to 24 VDC 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. Low Pressure Alarm Circuit
The ValveMate features a low pressure alarm output that
activates whenever pressure drops below the minimum
valve operating pressure of 60 psi (4.1 bar).
Function and circuitry is identical to the feedback circuit
described in #2.
See page 4 for deactivate/reactivate procedure.
4. Mechanical Contact Circuit
The ValveMate can be initiated via the closure of mechanical
contacts such as a relay or switch. Closure of the contacts
can be momentary (no less than 0.008 seconds) or
maintained. A new cycle will begin once the contacts
are opened and then closed again. Refer to the
schematic for proper installation.
Note: For applications using more than one 7000,
see pages 16 and 17 for connection instructions.

16 / Connecting More than One 7000
Connecting More than One 7000
Follow these instructions and diagrams
when the Voltage Initiate or End-ofCycle Feedback features are used in
a multiple 7000 installation.
1. Voltage Initiate Circuit
To start the dispense cycle for multiple 7000’s at the same time, connect
the Voltage Initiate Circuit, the Contact
Closure Initiate and the Low Pressure
Alarm Circuits in parallel as illustrated.
Note:
The amperage consumption for the
Voltage Initiate Circuit will increase with each
ValveMate 7000 that is connected. The initiate power supply should be sized accordingly.
Example: First 7000 consumes
15.0mA at 24 volts. Second one will
consume another 15.0mA; now total
is 30.0mA. Third one will consume
another 15.0 making the total 45.0mA
and so on.
17 / Connecting More than One 7000
2. End-of-cycle Feedback Circuit
This circuit will ensure that the Endof-Cycle will come from the last 7000
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 7000 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 & 4 must not exceed 30.0 VDC.
Example: The load to be operated
through the Feedback Circuit is 12
VDC. Four 7000’s are to be used.
4 X 2.0 = 8.0 VDC drop. Power
supply should provide (12.0 + 8.0)
or 20.0 VDC to ensure that 12.0 VDC
is available to run the load.
Stack mounting two or more ValveMate 7000’s.
Use the dimensions in the illustration to make up
mounting bracket from flat stock.
2. Series circuit for End-of-Cycle
