GENERAL INFORMATION
The SW1 is a three-way pneumatic solenoid valve
activated by a 24 VDC or VAC electric signal. The
miniature valve is light weight, energy ecient, and
capable of continuous duty. The LED indicates
power to the valve. The valve is equipped with two
plastic barbs and one metal barb, all of which accept
5/32" OD polyethylene or PVC tubing. A jumper
shunt is mounted in series with the incoming power
to allow local OFF override.
MOUNTING INSTRUCTIONS
The interface device may be mounted in any position.
If circuit board slides out of snap track, a non-conduc-
tive“stop”may be required. Use only ngers to remove
board from snap track. Slide out of snap track or push
against side of snap track and lift that side of the circuit
board to remove. Hold the valve in one hand when
installing tubing to prevent stress on board. Do not
ex board or use tools.
WIRING INSTRUCTIONS
PRECAUTIONS
• Remove power before wiring. Never connect
or disconnect wiring with power applied.
• When using a shielded cable, ground the
shield only at the controller end. Grounding
both ends can cause a ground loop.
• It is recommended you use an isolated UL-listed class 2 transformer when powering the unit
with 24 VAC. Failure to wire the devices with the correct polarity when sharing transformers may
result in damage to any device powered by the shared transformer.
• If the 24 VDC or 24VAC power is shared with devices that have coils such as relays, solenoids, or
other inductors, each coil must have an MOV, DC/AC Transorb, Transient Voltage Suppressor (ACI
Part: 142583), or diode placed across the coil or inductor. The cathode, or banded side of the DC
Transorb or diode, connects to the positive side of the power supply. Without these snubbers,
coils produce very large voltage spikes when de-energizing that can cause malfunction or
destruction of electronic circuits.
• All wiring must comply with all local and National Electric Codes.
Make electrical connections as follows:
1. Connect signal to either of the signal (SIG) terminals.
2. Connect the Common of the electrical signal to the terminal marked COM.
Apply signal to SIG and COM terminals. The unit may be warm to the touch when signal is applied for a
sustained period of time.

With the jumper in the AUTO position and signal applied, LED should be ON and SW1 will allow air to ow
from Common to N.C. port.
With jumper in the OFF position or when signal is removed, the LED should be o and air should ow
between the Common and N.O. port.

WARRANTY
The Interface Series are covered by ACI’s Two (2) Year Limited Warranty, which is located in the front of ACI’S
SENSORS & TRANSMITTERS CATALOG or can be found on ACI’s website: www.workaci.com.
W.E.E.E. DIRECTIVE
At the end of their useful life the packaging and product should be disposed of via a suitable recycling
centre. Do not dispose of with household waste. Do not burn.
