Direct-installation type DIN rail type Vacuum switch with visibility improved display, and one with analog output with reasonable price are selectable. There are 2 kinds in vacuum switch with display. One is 2 switch output and the other is analog output type. Connector wire is adopted which makes wiring layout easy. 189 VH VS VU VUM VY VB Max. 10 mounting units in a manifold type. Standard nozzle bore: 05(ø0.5mm), 07(v0.7mm) and 10(ø10mm). Copper alloy free and Low level ozone proof types are available in. No copper alloy on airflow path. HMBR material for seal rubber. Krytox grease is a measure against low ozone concentration and dry air. VM VC VRL VG VK VJ Piping Example Blow-off solenoid valve This valve ensures releasing a work-piece from a vacuum pad securely. Blow-off air is supplied during the power supply to the valve is ON. Suction solenoid valve This valve is to generate vacuum Vacuum switch with display suction. Vacuum level is easily adjusted by checking display. 2 types are available; One is 2 switch output and the other is analog output type. Besides, vacuum switch with analog output only which is reasonably priced is available. Turn the release needle to the right (clockwise) to reduce blow-off air and to the left (counterclockwise) to increase.

Detailed Safety Instructions Before using PISCO products, be sure to read Safety Instructions and Safety Instruction Manual on page 5-9 and Common Safety Instructions for Vacuum Series on page 7-9. Warning 1. The compressed air is dangerous if mishandled. It is recommended that a person having enough knowledge and experience carry out the assembling or maintenance of a machine or a device using pneumatic equipments. 2. At maintenance check of the product, shut electrical power supply and the air supply, and make sure to vent the residual pressure in the air circuit in advance. When installing or removing of a unit to/from a manifold, make sure to shut off air supply and to exhaust the residual pressure in the air circuit first.. The product is not explosive-proof. Do not use it in the environments containing flammable or explosive gases or liquid. Please avoid using in conditions that pressure of 0.1MPa or higher is continuously supplied to vacuum circuit.. The coil in a pilot solenoid valve generates heat under the following 1 to conditions. The heat may cause dropping life cycle, malfunctions, getting burnt or damaging peripheral machines. Contact us when the power is applied to the vacuum generator under the following conditions: 1 The power is continuously ON for over 2 hours. 2 High-cycle operation. Even when intermittent running of the generator is carried out, the total operation time per day is longer than non-operation time. 5. When the electricity is applied to valves continuously for a long time, the coils generate heat. It may cause dropping life cycle, malfunctions, getting burnt or damaging peripheral machines. EXTERNAL GENERATOR CONTROLLER PAD ACCESSORIES 21 Caution 1. The product shall be used within the operating pressure range. Otherwise, there are risks of damage or deformation. 2. Regarding double-solenoid types ( D- ), the switchover valve (main valve) is placed in neutral after the supply of pilot air has been suspended (the same is true when the valve is being operated for the first time after shipment). When resuming the supply of pilot air, be sure to send a signal to the pilot valve, or conduct switchover operations manually as required.. The increase of of manifold station may cause troubles such as performance drop by a shortage of air supply and insufficient capability to exhaust, and exhaust air leak to the vacuum port. Allowable station numbers of simultaneous operation differs by nozzle size, vacuum performance, and other conditions. Please contact us for details.. Although the exhaust of the model with a manifold type is silencer vent by each individual unit, the exhaust air of operating unit or blow-off air flows into the vacuum port of non-operating unit. If such exhaust air causes the problem, please contact PISCO. VQ VZ VN
ME SW S2 Vacuum Generator Series Vacuum Generator GENERATOR Safety Rules for Use Vacuum Switch with display (1) Pressure Setting Method 1 Turn on the power (Make sure the correct wiring and apply DC power to the vacuum switch). 2-1 Set the indicator switch at Pressure Setting Mode (ME S1 / S2 and SW) 2-2 (Vacuum switch with analog output) Fully turn the hysteresis setting trimmer (HYS) in the counterclockwise direction in order to minimize the hysteresis adjustment in advance. Adjust the pressure adjusting trimmer (S1 / S2 and SW) with a flathead screwdriver to set at the desired value. Set the indicator switch at ME and apply pressure and check the actual operation. (Vacuum switch with 2 switch output) Switch output 1 (S1): Red turns ON at the pressure with more than the setting. Switch output 2 (S2): Green turns ON at the pressure with more than the setting. (Vacuum switch with analog output) Switch output (SW): Red turns ON at the pressure with more than the setting. 217 VH VS VU (2) Differential response setting 1 Differential response setting can be adjusted by the hysteresis setting trimmer (HYS). 2 Differential response setting range is regulated within about 0-15% of the set value. Differential response setting becomes large when the trimmer is turned in the clockwise direction. Confirmation of Hysteresis Gradually increase and decrease the supply pressure around the set pressure value and read the value by a vacuum gauge when operation indicator lamp turns ON/OFF. The difference in the displayed values is taken as differential response. Hysteresis adjustment is useful for the following cases: I ncrease differential response when pressure pulsates with output repeatedly showing small on/off movements. When an allowable range is to be set for the lowering of pressure.

Safety Instructions for Vacuum Switch with display 1 Do not use the vacuum switch in the environment or gasses containing corrosive substance. It may cause a sensor trouble. 2 Wiring or ways by which noise or other disturbance is caused may cause a sensor trouble. Since the sensors are not explosive-proof, do not use them in an inflammable or explosive gas, fluid or atmosphere. Since the sensors are not drip / dust proof, do not use them in locations where they may be exposed to water or oil drops or dust. 5 Do not use the sensor in an atmosphere exceeding the range of application temperature or causing heat as sensor malfunction may result. Make sure to turn off the power before wiring. Check the wire colors, and do not short-circuit output terminals, power supply terminals and COM terminals when wiring. Short-circuits may cause a sensor trouble. 7 Do not give an excessive tensile strength and bending on a lead wire. Otherwise, breaking wire or damage on connector may be caused. 8 Instant application of pressure about 0.5MPa does not affect the sensor performance, but do not keep applying 0.2MPa or more constantly during blow-off air supply. It may be a cause of damaging the sensor. 9 When adjusting pressure and differential response, use a flathead screwdriver (accessory). Do not apply an excessive force on the trimmer and slowly turn it within its rotation limits. Otherwise, there is a risk of damaging the trimmer and the circuit board. 10Supply a stable DC power to the product. 11 Add a surge absorption circuit to relays or solenoid valves, etc. which are to be connected with output terminal and source terminal. Do not apply a current exceeding 80mA. 12 Ground the FG terminal when using a unit power source such as switching current. 1 Output terminals (lead wire color: black and gray) and other terminals should not be short-circuited. 1 Avoid strong external impacts and excessive fore to on the sensor body.

How to attach / detach and clean the nozzle and diffuser Pull out the diffuser with a pair of long-nose pliers after removing the cover and the diffuser retainer. Use a cushion material such as a sponge to cover the nozzle port to prevent the nozzle from jumping out. Apply the air to the vacuum generator (*5)and the nozzle comes out by the air pressure. Take out the cushion material and then take out the nozzle. Remove any foreign substance from nozzle, inside of diffuser by air blowing or wiping(*). Combine the nozzle with the diffuser and push them back into the body with the attention not to drop the nozzle. Place the diffuser retainer on the diffuser and tighten the cover with 0.2-0.25Nm of the tightening torque. For installation of the silencer element, refer to the section "How to replace the silencer elements."
