Take safety measures (e.g. mounting protective covers) when there is a danger of fingersbeing caught in a gripper or workpieces causing damage, etc.3. There is a danger of workpieces dropping if there is a decrease in gripping force due to adrop in circuit pressure caused by a power failure or trouble with the air source. It is necessary to take measures such as drop prevention so that injury and damage to machinery or equipment can be prevented.4. If the product is used for a purpose other than the transportation of a workpiece such aspositioning or clamping, please consult SMC.! Caution1. Finite orbit type guide is used in the actuator finger part. By using this, when there areinertial force which cause by movements or rotation to the actuator, steel ball will move to one side and this will cause a large resistance degrade the accuracy. When there are inertial force which cause by movements or rotation to the actuator, operate the finger to full stroke.2-2 Selection ! Warning1. The gripping point should be set within the limited range.When the gripping point distance becomes large, the gripper attachment applies anexcessively large load to the gripper sliding section, and causes adverse affects on the life of the gripper. Refer to the catalog for details.2. Attachments should be designed to be as light and short as possible(1) A long or heavy attachment increases the inertia force required to open or close thefingers. This may cause unsteady movement of fingers and have an adverse affect on the life of the gripper.(2) Design the attachment to be as short and light as possible even if the gripping point iswithin the limited range. Refer to the catalogue for details.L HHHL L ○ "L" and "H" are appropriate × "L" is too long × "H" is too long GrippingpointGripping point Gripping pointL Grippingpoint(3) Select a larger size gripper or used two or more grippers for handling a long and/or largeworkpiece.3.Provide a run off space in the attachment when using with a small or thin workpiece. If a runoff space is not provided, gripping becomes unsteady, and it may lead to gripping failure or slippage.4.Select a model that provides a gripping force with margin in relation to the workpiece weight. Incorrect selection may lead to dropping of the workpiece or othre troubles. Refer to the model selection criteria of each series for the effective gripping force and the workpiece mass.5. Do not use the product in applications where excessive external force or impact force is applied.This can result in failure. Please consult with SMC if necessary.6.Select a model having a sufficient working finger opening/closing width. < In case of insufficient width >(1) Gripping becomes unsteady due to variations in opening/closing width or workpiecediameter.(2) When using an auto switch, the detection may not be reliable. Refer to the Auto SwitchHysteresis section and set the stroke including the hysteresis length for reliable switch function. When using the water resistant 2-color indicator auto switch, the gripper stroke may be limited by the setting of the indicator color during detection.2-3. Installation ! Warning1. Install and operate the product only after reading the Operation Manual carefully andunderstanding its contents. Also, keep the manual where it can be referred to as necessary.2. Allow sufficient space for maintenance and inspection.3. Do not scratch or dent the air gripper by dropping or bumping it when mounting.Slight deformation can cause inaccuracies or a malfunction.4.

Tighten the screw within the specified torque range when mounting the air gripper.Tightening with a torque above the limit can cause malfunction, while insufficient tightening can cause slippage and dropping.How to Mount Air Gripper Axial mounting (Body tapped)Lateral mounting (Body tapped)Lateral mounting (Body through-hole)Refer to the catalogue for the dimension of the positioning pin.Attachment Use the holes on the bodyend surface for positioning.! Caution1. To mount the attachment to the finger, make sure not to apply undue strain on the finger.Any damage to the gripper may cause malfunction and reduce the accuracy. 2. Avoid external force to the finger.Fingers may be damaged by a continual lateral or impact load. Provide clearance toImpact load × No clearance C l e a r a n c eC l e a r a n c e○ Small clearance Impact load C l e a r a n c eInvert Impact load× No clearanceC l e a r a n c e○ Small clearance C l e a r a n c e3. Adjust the gripping point so that an excessive force will not be applied to the fingers wheninserting a workpiece.Confirm that the gripper can operate without receiving any shock by testing it in manual operation mode or by low speed operation.4. Control the opening/closing speed with the speed controller to avoid excessive high speedoperation.If the finger opening/closing speed is greater than necessary, impact forces on the fingers and other parts will increase. This can cause a loss of repeatability when gripping a workpiece and have an adverse effect on the life of the gripper unit. It may be difficult to adjust the speed using meter-out control depending on the piping condition. In this case, adjust the speed using meter-in control or with dual speed controllers.5. When elbow piping fittings are used, they may interfere each other or part of the airgripper, limiting the range for piping entry. Please use long elbow union: KQ2W or extension fitting to avoid this situation. Refer to the catalog for details.Impact load × Not aligned ○Aligned2-4Air supply! Warning1. Please contact SMC when using the product in applications other than with compressed air.2. Compressed air containing a large amount of condensate can cause malfunction ofpneumatic equipment. An air dryer or water separator should be installed upstream from filters.3. If condensate in the drain bowl is not emptied on a regular basis, the condensate willoverflow enter the compressed air lines. This will cause a malfunction of pneumaticequipment. If the drain bowl is difficult to check and remove, the installation of a drain bowl with an auto drain option is recommended.4. Use clean air.Do not use compressed air that contains chemicals, synthetic oils including organic solvents, salt or corrosive gases, etc., as it can cause damage or malfunction of equipment.Refer to "SMC Air Preparation System" for further details on compressed air quality.! Caution1. When extremely dry air is used as the fluid, degradation of the lubrication propertiesinside the equipment may occur, resulting in reduced reliability (or reduced service life)of the equipment. Please consult with SMC.2. Install air filters.Install an air filter at the upstream side of valve. A filtration degree of 5μm or less should be selected.3. Install an aftercooler, air dryer or drain catch before the filter and take appropriatemeasures.Compressed air that contains excessive foreign material may cause malfunction ofvalves and other pneumatic equipment.Therefore, take appropriate measures to ensure air quality, such as by providing anaftercooler, air dryer or water separator.4. Use the product within the specified fluid and ambient temperature range.If the fluid temperature is 5o C or less, the moisture in the circuit could freeze, causingdamage to the seals and leading to equipment malfunction. Therefore, take appropriate measures to prevent freezing.Refer to "SMC Air Preparation System" for further details on compressed air quality.2-5 Piping! Caution1. Refer to the Fittings and Tubing Precautions (Best Pneumatics) for handling one touchfittings.2.

This would cause spool(⑤) to rise upward. As the spool(⑤) rises, the air pressure will be supplied to the actuator(⑩). As the actuator's inner pressure increases, the actuator stem(⑫) will move. The movement will be transferred to cam(⑭) and pulls the span spring(⑮). The span spring(⑮)'s force will be balanced with torque motor(①), and this would cause to move flapper(②) to the normal position and reduce the gap between the nozzle(③). As the air pressure exhaustion level decreases through the nozzle(③), the pressure level in upper spool(⑤) increases again. The spool(⑤) would come back to the normal position and block the seat(⑦) which would lead to block the supply air from the actuator(⑩). When the actuator(⑩) stops the movement, the positioner would come back to the normal position. <Figure 1>Suffix SymbolYT-1000L series follows suffix symbols as follows.YT-1000L════════════════════════════════Motion Type S :LinearD :Double════════════════════════════════Explosion Proof m :Ex dm IIB T5C :Ex dm IIC T5:Ex ia IIB T6in :Non-Explosion════════════════════════════════Feedback Lever 1 :10 ~ 40mm:30∼ 70mm23 :60 ∼ 100mm4 : 100 ∼ 150mm════════════════════════════════Orifice 1 : Ø1Ø22:3 : None════════════════════════════════Connection Type 1 :PT2 :NPT════════════════════════════════Ambient Temperature S :-20 ~ 70℃H :-20 ~ 120℃L :-40 ~ 70℃════════════════════════════════* For special specification, please contact our sales department.Specification* Tested under ambient temperature of 20℃, absolute pressure of 760mmHg, and humidity of 65%.Please contact us for more detailed specification.* 1: For 1/2 Split Control, it can be applied by adjusting zero and span.*2: For inquiry regarding strokes under 10mm or above 150mm, please contact YTC.* 3: YT-1000L has different types of explosion proof certificates.

AfterTROUBLESHOOTING▶ Positioner does not respond to the input signal.(1)Check supply pressure level. The lever must be at least 1.4 kgf/cm2. Forspring-return type of actuator, the supply pressure level has to be larger than the spring's specification.(2)Check if input signal is properly supplied to the positioner. The signal should be4~20mA DC.(3)Check if zero point or span point is properly set.(4)Check if the positioner's nozzle has been blocked. Also, check if the pressure issupplied to the positioner and the pressure is being exhausted through the nozzle.If the nozzle has been block by any substances, please send the product forrepair.(5)Check if feedback lever has been installed properly.▶ The pressure of OUT1 reaches exhausting pressure level and does not come back down.(1)Check A/M Switch. If the switch has been damaged, replace the switch or pilotrelay valve.(2)Check for a gap or damages between the nozzle and the flapper. If damaged,please send the product to YTC for repair.▶ The pressure is exhausted only by A/M Switch.(1)Check if the positioner's nozzle has been blocked. Also, check if the pressure issupplied to the positioner and the pressure is being exhausted through the nozzle.If the nozzle has been blocked by any substances, please send the product toYTC for repair.▶ Hunting occurs.(1)Check if safety spring has been displaced. (Next to Pilot relay valve)(2)Check if the size of actuator is too small. If so, insert an orifice in order toreduce the pressure flow rate.(3)Check if there is any friction between the valve and the actuator. If so, increaseactuator's size or reduce the friction level.▶ Actuator only operates by On/Off.(1)Check actuator and positioner's acting type. Air pressure exhausts fromYT-1000L's OUT1 port as input signal level increases. Therefore, it is standard to connect to OUT1 port when single actuator is used. Make sure the spanadjustment is properly set according to the valve system.▶ Linearity is too low.(1)Check if positioner is properly positioned. Especially check if the feedback lever isparallel to the ground at 50% point.(2)Check if zero and span point have been properly adjusted. If either one of valuesis being adjusted, another one must be re-adjusted as well.(3)Check if supply air pressure level is stable from the regulator. If the level isunstable, the rgulator must be replaced.▶ Hysteresis is too low.(1)In case of double acting actuator, check if seat adjustment has been properlyperformed. Please contact YTC for any further inquiries regarding the seatadjustment.(2)Backlash can occur when the feedback lever and lever spring are loosen. Toavoid backlashing, please adjust the lever spring.(3)Check if the connection bar to the feedback lever is tightly fastened.Young Tech Co., LtdAddress:#662-8 Pungmu-Dong, Gimpo-City, Kyunggi-Do, South KoreaTelephone: +82-31-986-8545Fax: +82-31-986-2683Website: http://www.ytc.krUser Manual and other information on the documents are subjected to change without any notice.
