If suction flow changes, the vacuum will also be changed. Normally this relationship is expressed in ejector standard operating use. In graph, Pmax is maximum vacuum and Qmax is maximum suction flow. The values are specified according to catalogue use. Changes in vacuum are expressed in the below order. 1. When ejector suction port is covered and made airtight, suction flow becomes zero and vacuum is at maximum value (Pmax). 2. When suction port is opened gradually, air can flow through, (air leakage), suction flow increases, but vacuum decreases. (condition P1 and Q1) 3. When suction port is opened further and fully opened, suction flow moves to maximum value (Qmax), but vacuum is near zero (atmospheric ). As described above, the vacuum changes when the suction flow changes. In other words, when there is no leakage from the vacuum port, the vacuum can reach its maximum, but as the amount of leakage increases, the vacuum decreases. When the amount of leakage and the maximum suction fl ow become equal, the vacuum becomes almost zero. In the case when ventilative or leaky workpiece should be adsorbed, take note that vacuum will not rise. 6

Variable throttle 3 port valve filter generation and vacuum release are controlled by supply valve and release valve. A gauge is installed to visually check the vacuum during adsorption. The suction filter should be mounted to the location where the collected dust should not fl ow back due to release of air. (When using the 3 port valve, seal the R port of the release valve.) Ex. 5 upply/release valve (5 port valve with 3-position) + Variable throttle 5 port valve with 3-position closed centre ilencer Variable throttle Check valve Pressure switch (for vacuum) P # filter 3 port valve is used to generate and stop the vacuum (vacuum release is performed simultaneously).

Ex. 3 upply valve (3 port valve) + Variable throttle + filter + ilencer 5 port valve with 3-position closed centre is used to control the vacuum generation and release. A check valve is installed to the vacuum port to prevent vacuum from being reduced when the supply valve is OFF. A switch is installed in the vacuum circuit to detect. A suction filter should be mounted to the position where the duct collected by release air can be fl ushed by released air. The vacuum may leak depending on the check valve used. If a breathable workpiece is used, vacuum is reduced rapidly. ufficient verification is required before use. 3 port valve ilencer Variable throttle filter Power failure is prevented by changing the valve piping of Ex.2 and applying vacuum generation N.O. specifi cation.

For Equipment Precautions, refer to Handling Precautions for MC Products and the Operation Manual on the MC website, 1. oad to the ejector body The body material is resin, therefore do not apply load to the port after mounting. Prevent the operation which generates moment, as it may cause performance reduction or damage to the body. 2. tandard bracket It is possible to mount and remove the standard bracket, which is included with this product (option without bracket can be selected). Do not excessively expand or bend the bracket as it may break. The appropriate tightening torque for the standard bracket is shown below. For M3:.315 ±.3 N m For M4:.76 ±.8 N m Mounting screw Mounting Mounting of standard bracket (ZH18/2D A) and adjustment of vacuum (V) port 1) The standard bracket of ZH18/2D A can be mounted either by using mounting holes 1 or 2 (Fig.3). 2) When mounting the product through mounting hole 1, mount the bracket to the installation position first (Fig.3). 3) To mount the product to the bracket, push it down while directing the narrow rib and E mark on the adapter upward and the wider rib to the side (Fig.4). Hold the adapter when rotating the vacuum (V) port for adjustment. 4) To remove the body from the bracket, unclip the fingers (2 pcs.) on one side outside and pull the ejector up while rotating the adapter. If the ejector is pulled up without unclipping the fingers, it may damage the bracket (Fig.5, 6). If an increased holding force is required, please contact your MC sales representative. Bracket for ZH18/2D A Mounting screw Mounting of standard bracket (ZH5 to 1D A) and adjustment of vacuum (V) port 1) Align the recess of the bracket and protrusion of the adapter.

14 eries ZH pecific Product Precautions 2 Be sure to read this before handling. Refer to the back cover for afety Instructions. For Equipment Precautions, refer to Handling Precautions for MC Products and the Operation Manual on the MC website, t pacer Mounting Precautions for mounting with body mounting holes If models listed below are intended to be mounted on a plane surface through the body mounting holes, the outside diameter of the screw-in stud will interfere with the mounting surface. Therefore, use a spacer with a thickness 1 or above.

If the of the supply valve is insufficient, it may lead to vacuum failure. The selected supply valve should at least have the C factor shown in the table below. Minimum C Factor of a upply Valve Model C[dm 3 /(s bar)] ZH5 A.12 ZH7 A.23 ZH1 A.47 ZH13 A.8 ZH15 A 1.6 ZH18 A 1.53 ZH2 A Mounting of air equipment If particles are sucked through the vacuum (V) port during workpiece adsorption, the vacuum performance might be reduced due to adhesion of particles to air passage of the product or clogging of the exhaust passage (silencer). It is recommended to install an air suction filter (ZFA, ZFB, ZFC series) in the middle of the piping on the vacuum side to prevent performance reduction. If air containing moisture is sucked, vacuum performance might also be reduced due to the same reason. In this case, install a drain separator for vacuum (AMJ series). Piping 1. Piping diameter The piping diameter for each port should be the standard size of One-touch fitting. If the piping diameter is reduced, it may lead to insufficient flow of supply air, reduction of suction flow and reduction in the vacuum. 2. Exhaust port piping If there is any piping or silencer connected to the exhaust port, keep the back at 5 kpa or less. Increased back may lead to reduction of suction flow and delay in the transport cycle time. If a silencer is connected, the specified vacuum performance is reduced by 1 % or less. 3. One-touch fittings Refer to the one-touch fittings catalogue for more details about their piping and mounting precautions. 4. Piping to the female thread type When mounting a fitting to the screw-in stud (female thread), hold the width across flats with an appropriate size wrench. If the load is applied to the resin body directly, it may damage the body. 13 upply 1. Quality of supply air The compressed air supplied to the product should be cleaned in order to achive the following impurity content recommendation based on the grade of compressed air quality 2.4.3, and of IO8573-1: 21 (JI B8392-1: 212) If impurity enters the product, vacuum performance might be reduced due to deterioration of air passage and clogging of exhaust system.

15 eries ZH pecific Product Precautions 3 Be sure to read this before handling. Refer to the back cover for afety Instructions. For Equipment Precautions, refer to Handling Precautions for MC Products and the Operation Manual on the MC website, 1. Intermittent noise during vacuum generation When the ejector standard supply is close to the that generates peak vacuum, vacuum may become unstable due to fluid vibration. If there is any operation failure or the intermittent noise needs to be reduced, increase or decrease the supply. Avoid the supply range where the vacuum becomes unstable. 2. Temperature reduction and vapour condensation during vacuum generation When the ejector generates vacuum, compressed air expands adiabatically after passing through the nozzle. The temperature around the nozzle is reduced, so condensation might be generated on the product surface (the condensation dew point may vary depending on the temperature and relative humidity of the operating environment). 1. Exhaust air Ejector Characteristics When Ejector Operates If solid substances are sucked in through the vacuum (V) port, they will be discharged from the exhaust port with high speed, if the exhaust (EXH.) port is opened. Therefore, do not look into the exhaust port and direct the exhaust port toward a person when the ejector is operating. 2. Exhaust noise Models with large nozzle diameter generate a large exhaust noise if the exhaust (EXH.) port is opened. Install a piping or silencer to the exhaust port to reduce the exhaust noise. 14
