1 Pressure Gauge Feature The compact-size pressure gauges can be installed in small spaces. With the built-in tube fitting type, tube connection is the only necessary step before pressure indication.

3 Pneumatic Vacuum Switch To enhance visibility, an ED display is used for the vacuum switch. ED displays are used for set-up pressure and impression pressure. Two types of vacuum switch equipped with two-point output and analog output are provided. The application determining which should be used. In respect to wiring, a connector system has been chosen for ease of layout. Three pipe connection methods are offered: one-touch, M5 metric female screw, and direct connection. The application will determine which method is the most appropriate. Output detection accuracy is enhanced by the use of electronic switches. NPN opencollector output PNP opencollector output With 2-point output switch With analog output switch efore using the PISO device, be sure to read the "Safety Instructions", "ommon Safety Instructions for Products isted in This Manual" on page to and "ommon Safety Instructions for ontrol Series" on page 59 and "ommon Safety Instructions for ED Digital Pressure Sensors, Digital Pressur Sensors & Pressure Sensors" on page The cable can be connected to or disconnected from the connector. ut avoid connection and disconnection unless it is absolutely necessary, for it will put burdens on the cable or the board. 1. Although performance will not be affected even when pressure of around 0.5MPa (72.5psi) is applied, avoid continued application of pressure greater than 0.2MPa (29psi) during vacuum breaking. Prolonged application of such pressure may possibly cause damage to the sensors. 2. To set pressure and differential response, turn trimmer slightly with a screw driver within the prescribed range of rotation. Trying to adjust trimmer rotation by applying excessive force may possibly damage to the trimmer and base board. 3. As for power, use a stable direct current. 4. Insert a surge voltage absorption circuit in relays connected to output terminals and power source terminals (relays, electromagnetic valves, etc.). Do not use an electric current exceeding 0mA. 5. Ground the FG terminal when unit power souces, such as a switching power source unit, are used.. Do not short-circuit output terminals (black with a gray lead wire) and other terminals. 7. Avoid strong impacts and excessive force to the sensor body.. To install the sensor, use the specially prepared M2.5 screw. Tighten it to the recommended torque. 9. Fluid used must be kept in a pristine state. VUS21-4 VUS21 - VUS21 - VUS21 -F 79 VUS21 -M5

4 Sensor Heads, Separate display type Pressure sensor and Vacuum switch Small-sized 24.5-mm pressure sensors (width: 10mm height, 10mm total length). "Union," "Nipple," and "Male screw" are prepared. Use of an analog output type and indicator (SED30-series) has made a separate display system possible. Our small-sized pressure sensors can handle "positive pressure," "negative pressure" and "ompound pressure". oncerning output, a total of six different specifications are prepared. Standard cable length is 3m. A large 31.4mm square size indicator is used, realizing a high level of visibility with its large-sized ED display. All settings can be made using just three push buttons. For indication units, you can choose from among 11 different types. Two different kinds of output methods are offered - analog output and switch output. Four (4) different kinds of installation stays are available depending on installation form. - for installation in the rear, on a flat surface, panel-buried, and for protection of display components.

Insert surge-absorbing circuits into relays, valves, etc. Do not arbitrarily use these units at currents that exceed rated levels. 3. When using unit power sources, such as switching power sources, be sure to ground their FG terminals. 4. Take the utmost care to avoid short-circuitting the output terminal with other terminals. 5. Do not apply excessive loads to pressure sensors. Subjecting them to excessive loads can damage them.. Do not wire nozzles and other components in a way that will impress them with noises, etc. Do not use them in any arbitrary manner, either. Doing so can cause malfunctions. 7. When conducting pressure adjustments for units fitted with switch output sensors, use small screwdrivers (included). Do not apply excessive force to these screwdrivers, and turn them slowly. Applying excessive force may damage the units.. Our indicator (SED-30) is not constructed to be drip- or dust-proof. As such, do not use indicators that have been exposed to water or oil and/or dust. 9. For the SED-30 indicator s sensor heads, use either a VUS 11 A. or an SEU 11 A type head. Using different specifications with these sensor heads will not achieve the required level of accuracy. 10. Do not pull or bend vacuum switch lead wires excessively. Doing so may result in lead wires being snapped off and connector components broken.
