Automation Components, Inc.2305 Pleasant View Road | Middleton, WI 53562Phone: 1-888-967-5224 | Website: workaci.comPage 1Version: 4.0I0000592GENERAL INFORMATIONThe SW1 is a three-way pneumatic solenoid valveactivated by a 24 VDC or VAC electric signal. Theminiature valve is light weight, energy efficient, andcapable of continuous duty. The LED indicatespower to the valve. The valve is equipped with twoplastic barbs and one metal barb, all of which accept5/32" OD polyethylene or PVC tubing. A jumpershunt is mounted in series with the incoming powerto allow local OFF override.MOUNTING INSTRUCTIONSThe 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 fingers to removeboard from snap track. Slide out of snap track or pushagainst side of snap track and lift that side of the circuitboard to remove. Hold the valve in one hand wheninstalling tubing to prevent stress on board. Do notflex board or use tools.WIRING INSTRUCTIONSPRECAUTIONS• Remove power before wiring. Never connector disconnect wiring with power applied.• When using a shielded cable, ground theshield only at the controller end. Groundingboth ends can cause a ground loop.• It is recommended you use an isolated UL-listed class 2 transformer when powering the unitwith 24 VAC. Failure to wire the devices with the correct polarity when sharing transformers mayresult 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, orother inductors, each coil must have an MOV, DC/AC Transorb, Transient Voltage Suppressor (ACIPart: 142583), or diode placed across the coil or inductor. The cathode, or banded side of the DCTransorb 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 ordestruction 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 asustained period of time.FIGURE 1: DIMENSIONSINTERFACE SERIESInstallation & Operation InstructionsSW1 Phone: 1-888-967-5224Website: workaci.com1.67”(42.54mm)3.25”(82.55mm)1.80” (45.72mm)3.25”(82.55mm).70”(17.78mm) |
