详细说明：韩国银河NA系列norma电动执行器操作维护手册pdf,韩国银河NA系列norma电动执行器操作维护手册 OONOAH General △ CAUTION Before Handling the actuator, please read instruction manual and be well aware how toto do NA Series actuator is a engineered products which has been designed for usage of automation of 90 rotary valve or same operating principle equipment. Internal provisions like as self-locking which prevent reverse action from valve, Manual Override, and mechanical torque switches(except for NAO6&09)which protect actuator from overload Space heater for anti-condensation provide optimum condition for actuator operation Enclosure Al alloy enclosure is treated by Hard-anodized and powder coated Therefore it can be used under severe corrosive atmosphere All enclosures are designed to provide iP67grade ingress protection with explosion proof structure and to provide best performance under any circumstances Performance and applicable range 13 model of na06.09.15.19.28.38.50.60.80.100.150.200.250 provide various torque 6Kg. m- 250Kg. m and these are suitable for operation of 50A-600A of butterfly valve, 40A-400A of Ball valve, and other g0 rotary equipment like as Damper OONOAH General Lubrication and convenient installation for any direction NA Series actuator has double worm gearing and the mechanism is fully filled with grease There is no leak of lubricant because housing is totally enclosed structure Therefore installation for any direction is possible on the purpose Inspection, Measurement and test The performance and quality of NA Series actuators are certified by factory through out the leak, torque test and other necessary measurement after assembly and 100% certified product only delivered to customer Temperature, Humidity and Altitude NA Series actuators are designed suitable for following condition User should note these conditions when you select actuator Ambient Temperature -10°C-55C Max. Temp. of fluid 80°C Relative humidity :RH90% Altitude Lower than 1000m OONOAH Commissioning 1. Please check if the supplied actuator is suitable one for your application 2. Please check Model, Mounting base, Electrical specification and options comparing to your specification for puschasing (Can check these on the name plate mounted on actuator) For your information, EMIcO recommend Na series actuator for your Butterfly /Ball valve as follows. Model Butterfly Valve Ball valve(2-way) Ball valve(3-way) NAo6 80A 40A NA09 100A 50A 40A NA15 125A 65A 50A NA19 150A 80A 65A NA28 200A 100A 80A NA38 250A 100A NA50 125A NA60 300A 150A 125A NA80 350A 150A NA100 200A NA150 4004450A NA200 500A 250A 200A NA250 600A 300A 250A o Above table shows suitable size of actuator for valves which work under 10Kg/Cm of operating pressure If you need more information, please consult with factory or regional representative 3. Because Electric wiring diagram, test report and instruction manual are supplied together with actuator, please check if these are supplied or not 4. Please check tool and screw set for installation △ Caution 1. When you handle actuator which is not completely installed, please make sure that power should not be supplied into the actuator OONOAH Commissioning 2. If limit switches are not set yet, please make sure that actuator should not be fully open or close Actuator should be stored at dry and clean place if it is not immediately installed after delivery The place should There should be no severe vibration and temperature change in the place. If it is high humidity, power should be supplied at least every two week in order to operate the heater to prevent condensation Also, please do not remove the plug which mounted into actuator cable entry until wiring is ready in the field E CAUtIon △ If trouble due to inappropriate storage and place, EMICO can not guaranty the performance and quality OONOAH Commissioning Please be careful not to operate actuator to fully close or fully open until the direction of actuator is not confirmed(Especially 3 phase electricity) Also if limit switches are not completely set yet, it can be a major cause of damage of valve and actuator (Limit switches are already set when delivery, limit switches can be set again in the field if necessary) It is very simple to operate actuator by manual or electrical as follows Manual operation If you want to operate actuator by manual, pull the lever ( toward handwheel), so that clutch is to be engaged with handwheel If it is engaged, then you can operate actuator to any direction by manual Direction Indication of Open and Close is marked on the handwheel and handle cover and in general, to turn clockwise is close and counter clockwise is open Electrical operation After completion of wiring, you can operate actuator by switch in the Local panel If electricity is supplied, actuator automatically returns from manual to electrical operation mod If lever lean toward opposite side of handwheel, you can acknowledge it as electrical operating mode OONOAH Indication The Indication of valve position is done by indicator which is shown through the window of actuator top cover CLOSE CLOSE 卫mz Tm 彐s15 Open Close Indicator is designed same as shape of disc of butterfly valve and user can easily acknowledge the valve position from a distance OONOAH Electrical wiring Taking off Top cover By using the L-wrench, unscrew the screw of top cover and take off the top cover from assembly Electrical wiring Wiring should be done as per the wiring diagram which is provided together with actuator. Especially electricity (voltage, phase and hertz should be confirmed comparing to the details on nameplate △ Eh Warning Relays for power supply should not be connected to more than two actuators Grounding, Heater and internal wiring 1. Grounding lug in actuator and outside of actuator should done Connect the grounding wire to the position of the following mark 2. Wiring to heater should be done 3. Please make sure that wiring to terminal block should be tightly done 4. When wiring to terminal block, there should be some gap between the wires in order to prevent electric shortage due to the interference between the wires 3Phase(220V, 380V or 440V or others)electric power Danger △ NEVER connect phase conductors( L1, L2, L3)or neutral conductor(N) to the protective earth terminal marked pe OONOAH Electrical wiring Because there is no way to identify each phase among 3 phase,user should confirm the actuator correct rotating direction Otherwise, it can be a major problem of motor burning In order to check correct rotating direction for start up, followings should be done Make valve disc 45 position by using manual handwheel of actuator 2. Push the Close or Open switch for approx. 3seconds, check the rotating direction of valve disc 3. f direction of valve disc is reverse, immediately stop the actuator and check the wiring again Then change 2 wires each other among 3 wires(UVW) Single phase (110v or 220V)Power When wiring, please be careful not to supply power to open and close terminal simultaneously. This is a major cause of motor burning and after service at free of charge is impossible A caution Without confirmation rotating direction of 3 phase, actuator ca be operated in reverse direction. In this case, limit switches can not function and therefore Jamming of gearing or motor burning can occur. This is not a trouble which free after service is applicable. others after wiring After completion of wiring, make internal wires well arranged by using cable tie etc and remove substance in the actuator if any in order to avoid any trouble due to the substance After completion of all wiring and arrangement in internal, put the top cover on the housing and fasten the 4 retaining screws
