1 ariety of modularized units enable selections of integrated type ejector units suitable for the application. K eries Nozzle diameter: ø0.5, ø0.7, ø1.0, ø1.2 ZM Q G Y H U B C K KM J JM X XM Features acuum switches with displays and inexpensive easy-to-use mechanical vacuum switches are available. acuum switches with displays are used for 2- or 1-point switch output + analog output, enabling selections suiting use. Modules and a wide range of combinations enable you to choose the optimum module for your work purpose. The solenoid valve or air timer vacuum break valve can be used. A switching valve ensures that short-time vacuum break air blow and break air can be fine-tuned. For nozzles 05 (ø0.5mm), 07 (ø0.7mm), (ø1.0mm), 12 (ø1.2mm) are available as standard. pecifications Descriptions Working fluid K Compressed air Working pressure range Ma 0.25 to 0.7 Ambient temperature range 5 to 50 Lubrication Ejector characteristics Model no.

This abnormal noise is because characteristics are unstable and increases with instability. This may adversely affect the sensor, etc. Reset supply pressure. (Example1: When the H vacuum ejector operates with a base pressure of 0.5 Ma, an abnormal noise sounds when supply pressure drops to 0.43Ma due to a pressure drop.

21 K eries afety precautions Refer to Intro 13 for the general precautions of the vacuum system components. CAUTION The cartridge joint, timer cylinder, and element can be removed for maintenance by pulling out the set pin. Check that the set pin is securely inserted after parts are installed. ZM Q G Y H U B C K KM J JM X XM Do not remove the gripper at the main unit connection. Removing and reattaching it too often may weaken the connection and damage the main unit. The working temperature range of the vacuum ejector unit K is 5 to 50. Do not use this ejector at other temperature condition. Compressed air contains a lot of drainage (water, oxidized oil, tar, and substance) that may adversely affect the K's performance. Dehumidify air with After Cooler or Dryer and improve air quality. Do not use a lubricator. Rust, etc., in piping can result in operation faults. Install a 5μm or smaller filter before the supply port. Avoid using this vacuum ejector unit in environments with corrosive gas or flammable gas. Do not use this unit for fluids. Avoid suck dust, salt, iron chips, and etc. Do not operate the vacuum release solenoid valve when generating a vacuum. recautions for using the manifold Increasing the number of manifold stations may adversely affect performance or cause problems due to the causes below. Consult with CKD for details. 1. Drop in vacuum performance due to insufficient air supply. Countermeasure: 1 Check the air supply capacity, etc. 2 Keep piping as short as possible. 3 Increase joint size. 4 If using single-end supply, supply from both ends of the manifold. 2. Drop in exhaust port capacity causing vacuum performance to drop or exhaust air to be discharged from another station's vacuum port. The number of manifold stations depends on nozzle size and vacuum performance, etc. Check with a CKD sales Office. Cause When using a silencer (open air), insufficient silencer capacity causes exhaust resistance to increase and performance to drop. Countermeasure: 1 If using a single-end silencer, change to double-end silencer. 2 rovide separate exhaust for each station. (Custom made) 3 Avoid exhaust at walls. 4 Reduce the number of stations. Cause When using a common exhaust, performance drops when piping resistance is large. Countermeasure: 1 If using a single-end exhaust, change to double-end exhaust. 2 Keep piping as short as possible. 3 Increase exhaust joint size. 4 rovide separate exhaust for each station. (Custom made) 5 Reduce the number of stations. 5 When unit combination G, J, or L is selected, methods not moving all units simultaneously will cause the ejector exhaust in the moving ejector to flow into the unit s vacuum port. This can cause problems with exhaust, so contact CKD.

(vacuum switch with analog output) witch output (W): The operation ( red) turns on when set pressure is exceeded. (2) etting hysteresis 1 Hysteresis is adjusted using the hysteresis setting trimmer (HY) 2 Hysteresis is adjusted from 0 to 15% of the setting. Hysteresis increases when the trimmer is turned to CW. 3 Checking hysteresis et the display change switch to pressure display mode (ME) and gradually increase and decrease pressure near the set pressure. Read values at which the operation indicator turned on and off. The difference in displayed values is hysteresis. 4 Example of hysteresis adjustment If pressure has a pulse and output is thin and intermittent, use large hysteresis.

23 K eries How to use 2. recautions for vacuum switch with display ZM Q G Y H U B C K KM J JM X XM 1 Do not use this vacuum switch in fluids or in an atmosphere with corrosive substances. The switch could be damaged. 2 Do not use wiring or applications that may cause noise (surge), etc., to be applied. The switch could be damaged. 3 Do not use this vacuum switch in an atmosphere containing fluids or flammable or explosive gasses. This device is not explosionproof, so faults may occur. 4 Do not use this vacuum switch where it may be exposed to water, oil, or dust. This device is not drip-proof, so faults may occur. 5 Do not use this vacuum switch for applications that generate heat exceeding the working temperature. The switch could be damaged. 6 Turn power off before wiring. Check the lead wire color during wiring, and check that the output terminal, power terminal, and COM terminal are not short-circuited. The switch may fail if these terminals are short-circuited. 7 Do not apply excessive tension or bend the connector cable excessively. Wires and connector section may break. Check that pressure exceeding 0.2 Ma is not constantly applied during a vacuum release. Constant application of this pressure may damage the switch. 9 When setting pressure or hysteresis, use a small screwdriver, and gently turn the trimmer within its rotation range. Do not force it. The trimmer or CB may be damaged if excessive force is applied during adjustment. Use stabilized DC power. 11 Insert a surge voltage absorption circuit in the relay or solenoid valve, etc., connected to the output terminal or power terminal. Avoid uses in which current exceeds 0mA. 12 Ground the FG terminal when using unit power, such as switching power. 13 Do not short-circuit the output terminal (black or gray lead) with other terminals. 14 Do not apply excessive external impact or force to the switch. 3. Mechanical vacuum switch The vacuum ejector K vacuum switch uses a connector leads. Refer to the following drawing and wire. To adjust pressure, twist off the cover with a screwdriver, etc., and adjust with the setting screw. The set vacuum degree increases when the screw is turn to the right (CW). The adjustment screw is fixed with a lock nut. Loosen the lock nut before adjusting the screw. After adjustment, fix the adjustment screw with the fingers, etc., and tighten the lock nut. When removing the cover, hold it lightly so it does not pop off. * If the switch fails, contact a CKD ales Office.

Keep vacuum piping as short as possible when using the vacuum ejector K with the vacuum switch. If vacuum piping is too long, piping resistance increases when vacuum is generated. The vacuum at the sensor may be high even when no suction exists. This may cause switch faults. If piping must be long, install a discrete sensor, such as a pad, near the end of piping. 60

24 How to use K eries How to use 5. How to adjust the vacuum break valve acuum break air (solenoid valve type vacuum release valve, air timer type vacuum release valve) Turning the vacuum release air adjustment needle to right (CW) decreases the release air flow and turning it to left (CCW) increases it. Break time for air timer type vacuum break valve To adjust break time for the air timer type vacuum break valve, turn the vacuum break time adjustment needle. When turned right (CW), the break time will increase, and when turned left (CCW), it decreases. 6. Fixing method Flow large Break time short Flow small acuum break air flow control needle Break time long acuum break time adjusting needle Fix the vacuum ejector K with M3 screws using the fixing holes on the resin body.
