Using an adjustable frequency drive with a soft starter bypassToday’s most complete drive packages oftencombine several different solutions together inorder to provide the most reliable and robust sys-tem available. This application paper will discussthe advantages of using a drive with a soft starterbuilt into the bypass.Contactors, soft starters, and drives aredifferent devices that can be used to control amotor. A contactor simply connects the motordirectly across the AC line. A motor connectedto the AC line will accelerate very quickly to fullspeed and draw a large amount of current duringacceleration. A soft starter is a device used toslowly ramp up a motor to full speed, and/orslowly ramp down the motor to a stop. Reducingboth current draw and the mechanical strain onthe system are big advantages of using a softstarter in place of a contactor. Many large pumpsand fans require at least a 30-second ramp timeto prevent mechanical damage to the system.Soft starters are more common on larger horse-power systems. An adjustable frequency drivenot only has the ramping ability of a soft starter,but also allows the speed to be varied, whileoffering more flexibility and features.Enclosed adjustable frequency drives ofteninclude a bypass when used in applications thatcan not afford downtime. A bypass configurationconsists of three contactors: one contactordisconnects the drive from AC power, anotherdisconnects the motor from the drive, and thelast contactor connects the motor directly to theAC line. See Figure 1 on the next page for atypical three-contactor bypass configuration.A bypass provides peace of mind guaranteeingthat the system will continue to run, even in theevent of a drive failure. However, many designersoverlook the possibility of adding a soft starterinto the bypass. A soft starter can be added inline with the bypass contactor that connects themotor directly across the line. See Figure 2 on thenext page for a typical three-contactor bypasswith an integral soft starter.If an application is using an adjustable frequencydrive because a contactor is not acceptable, thena contactor-only bypass should not be acceptableeither. Adding a soft starter to the bypass allowsthe motor to be ramped up to full speed, thusreducing the mechanical and electrical stress onthe system.The best overall motor control package starts witha drive to provide the greatest amount of control,flexibility, and protection. Adding a bypass withan integral soft starter provides a backup systemto run the motor should the drive fail. Large drivesystems should have soft starters in the bypass,otherwise the application risks negatively affect-ing the power system, damaged bearings, or bentshafts once the bypass is engaged.Eaton Corporation Electrical Sector 1111 Superior Ave.Cleveland, OH 44114United States877-ETN-CARE (877-386-2273)© 2009 Eaton Corporation All Rights Reserved Printed in USAPublication No. AP03902004E / Z9003August 2009PowerChain Management is a registered trademark of Eaton Corporation.

Series WE04 2-Piece Flanged Stainless Steel Ball ValveSpecifications - Installation and Operating InstructionsBulletin V-WE04The SERIES WE04 incorporates a full port 2-piece flanged SS ball valve for great flow rates with minimal pressure drop. The valve features a blowout proof stem for added safety, reinforced PTFE seats and seals for longer life, and a 316 SS (ASTM CF8M) ball for better performance. Actuators are direct mounted creating a compact assembly for tight spaces. Limit switches are able to be mounted directly to the valves allowing for remote position indication.The Series WE04 can be configured with either a pneumatic or electric actuator. Electric actuators are available in weatherproof or explosion-proof, a variety of supply voltages, and two-position or modulating control. Two-position actuators use the supply voltage to drive the valve open or closed, while the modulating actuator accepts a 4 to 20 mA input for valve positioning. Actuators feature thermal overload protection and permanently lubricated gear train.The pneumatic double acting actuator uses an air supply to drive the valve open and closed. The actuator has two supply ports, with one driving the valve open, and the other driving the valve closed. Spring return pneumatic actuators use the air supply to open the valve, and internally loaded springs return the valve to the closed position. Also available is the SN solenoid valve to electrically switch the air supply pressure between the air supply ports for opening and closing the valve. Actuators are constructed of anodized and epoxy coated aluminum for years of corrosion freeservice.WE04-DHD00WE04-DTD01-AWE04-DDA02-NN09WE04-CTI01-ABy DwyerVALVE BILL OF MATERIALSVALVE DIMENSIONAL DRAWINGAUTOMATED VALVE DRAWINGSW/ PNEUMATIC ACTUATORW/ ELECTRIC ACTUATORW/ EXPLOSION-PROOF ELECTRIC ACTUATORPNEUMATIC ACTUATORNote: For optimal operation, pneumatic actuators should be run with a supply of clean, lubricated air.Spring Return Actuator OperationAir to PORT 2 (the left hand port) causes the actuator to turn counterclockwise (CCW). Loss of air to PORT 2 causes air to exhaust and the actuator turns clockwise (CW). This is the FAIL CLOSE operation.Double Acting Actuators OperationAir to PORT 2 (the left hand port) causes the actuator to turn counterclockwise (CCW). Air to PORT 1 (the right hand port) causes the actuator to turn clockwise (CW).Pneumatic Actuator MaintenanceRoutine maintenance of pneumatic actuator:• Keep the air supply dry and clean• Keep the actuator surface clean and free from dust• Periodic checks should be done to make sure all fittings are tight• Pneumatic actuators are supplied with lubrication to last the entire life span of the actuator under normal operating conditions.The outer surface of the pneumatic actuator should be clean to avoid friction or corrosion. All fittings and connections should be tight to prevent leaks during operation. Check the bolts mounting the valve to the actuator to make sure they have not come loose during shipping or installation. Make sure the valve and actuator are not rubbing or jamming against other components during operation. The actuator should be inspected annually to make sure all fittings and bolts are tight and nothing has come loose during operation.Disassembling Pneumatic ActuatorsBefore beginning disassembly, ensure that the air supply to the actuator has been disconnected, all accessories have beenremoved, and that the actuator has been disassembled from the valve.1. Loosen the end cap fasteners (23) with a wrench (size varies depending on actuator model). On the spring return actuator, alternate 3 to 5 turns on each fastener until the springs are completely decompressed. Use caution when removing the cap since the springs are under load until the fasteners are fully extended.2. Remove the pinion snap ring (13) with a lock ring tool. The indicator (12) may now be removed.3. Turn the pinion shaft (2) counter clockwise until the pistons are at the full end of travel. Disengage the pistons (15) from the pinion. (Note: Low pressure air--3 to 5 psi MAXIMUM--might be required to force the pistons completely from the body.) Note the position of the pistons before removing them from the actuator body.4. Remove the pinion through the bottom of the actuator. The actuator is now completely disassembled.Be sure the actuator surfaces are free of debris and scratches before reassembling.1. Apply a light film of grease to all O-rings and the pinion before replacing.2. Put the pinion (2) back through the actuator with the flats of the pinion shaft running parallel with the body.3. When reassembling the actuator, make sure that the piston racks are square to the actuator body and returned to their original orientation. (Note: The normal operation of all spring return pneumatic actuators is FAIL CLOSED. To change the orientation to FAIL OPEN, rotate the racks 180º to create a reverse operation.4. When replacing springs in a spring return actuator, ensure that the springs are replaced in their identical position in the end cap from which they were removed. (Note: In some circumstances, you might want to change the standard 80 pound spring set to fit your application and available air pressure.5. Seal the end caps with a petroleum lubricant and bolt to actuator body.6. Check the seal of the actuator by covering seal areas (pinion, end caps) with soapy water and using low pressure air to the actuator to ensure that no bubbles are produced.Pneumatic Actuators Bill of MaterialsReassembling Pneumatic ActuatorsELECTRIC ACTUATORSElectric Installation1. Operate valve manually and place in the open position.2. Remove any mechanical stops the valve might have. (DO NOT REMOVE ANY PARTS NECESSARY FOR THE PROPER OPERATION OF THE VALVE, SUCH AS THE PACKING GLAND, PACKING NUT, ETC.)3. Ensure that the actuator output shaft and valve stem are aligned properly. If they are not, operate the valve manually until they are correct.4. Remove actuator cover.5. Bring power to the actuator. CAUTION: Make sure power is OFF at the main box.6. Wire the actuator per the diagram attached to the inside of the cover. Special actuators (those with positioner boards, etc.) will have diagrams enclosed inside the cover.7. Securely tighten bolts used to mount the actuator to a mounting bracket or directly to the valve mounting pad if it is ISO5211 compliant.8. Cycle the unit several times and check the open and closed positions of the valve. Cams are pre-adjusted at the factory; due to the variety of valve designs and types however, slight adjustments might be required.9. Replace cover and tighten screws.To Set The Open Position1. Cycle the valve to the open position by applying power to terminals. The top cam and switch control this position. In the open position, the set screw in the top cam will be accessible.2. If the valve is not open completely:A. Slightly loosen the set screw on the top cam.B. Rotate the cam clockwise (CW) by hand until the switch makes contact. Contact is made when a slight click can be heard. By making incremental CW movements of the top cam, the valve can be positioned precisely in the desired position.C. When the top cam is set, tighten the set screw securely.3. If the valve opens too far:A. Apply power to terminals. This will begin to rotate valve CW. When valve is fully open and in the exact position desired, remove power from actuator.B. Loosen the set screw in the top cam.C. Rotate the top cam counterclockwise (CCW) until the switch arm drops off the round portion of the cam onto the flat section. A slight click can be heard as the switch changes state.D. Continue applying power to terminals until valve is in the desired position.To Set The Closed Position1. Apply power to terminals to move the valve toward the closed position. The bottom cam and switch control the closed position. In the closed position, the set screw in the bottom cam will be accessible.2. If the valve is not closed completely:A. Slightly loosen the set screw on the bottom cam.B. Rotate the cam counterclockwise (CCW) by hand until the switch makes contact. Contact is made when a slight click can be heard. By making incremental CCW movements of the bottom cam, the valve can be positioned precisely in the desired position.C. When the top cam is set, tighten the set screw securely.3. If the valve closes too far:A. Apply power to terminals. This will begin to rotate valve CCW. When valve is fully closed and in the exact position desired, remove power from actuator.B. Loosen the set screw in the top cam.C. Rotate the top cam clockwise (CW) until the switch arm drops off the round portion of the cam onto the flat section. A slight click can be heard as the switch is no longer making contact with the round part of the cam.D. Continue applying power to terminals until valve is in the desired position.Electric Actuators Wiring Diagram: ACT-TI & ACT-MIWiring Diagrams forTI01-A to TI05-A: 110 VAC, TI01-B to TI05-B: 220 VAC, TI01-C to TI05-C: 24 VACHOTALVE ALVEWiring Diagrams for TI01-D to TI05-D: 24 VDCOPERATION:POWER TO 1 & 2 FOR CCW ROTATION POWER TO 3 & 4 FOR CW ROTATION TERMINALS 5 & 6 FOR FIELD LIGHT INDICATION CONNECTIONSW.#1 SW.#2SWITCH #1 OPEN SWITCH SWITCH #2 CLOSE SWITCHWiring Diagrams forMI01-A to MI05-A: 110 VAC, MI01-B to MI05-B: 220 VAC, MI01-C to MI05-C: 24 VACSW. 1, CLOSESW. 2, OPEN .SW. 3, CLOSE SW. 4, OPEN Wiring Diagrams forMI01-D to MI05-D: 24 VDCSW. 1, CLOSESW. 2, OPEN .SW. 3, CLOSE SW. 4, OPENElectric Actuators Wiring Diagram: ACT-TD & ACT-MDWiring Diagrams forTD01-A to TD03-A: 110 VAC, TD01-B to TD03-B: 220 VAC,TD01-C to TD03-C: 24 VACWiring Diagrams forTD01-D to TD03-D: 24 VDCWiring Diagrams forMD01-A to MD03-A: 110 VAC, MD01-B to MD03-B: 220 VAC,MD01-C to MD03-C: 24 VACNote: To speed up installation of the control wires to the ACT-MDXX modulating actuator, it is recommended to remove the control module from the actuator. The control module can be removed by removing the two mounting screws on the left and right of the control module. Install the control wires to the correct terminal points and then reinstall the control module.Electric Actuator MaintenanceOnce the actuator has been properly installed, it requires no maintenance. The gear train has been lubricated and in most cases will never be opened. Duty Cycle Definition“Duty Cycle” means the starting frequency.Formula: Running Time ÷ (Running Time + Rest Time) x 100% = duty cycle –> Rest Time = Running Time x (1 - duty cycle) ÷ duty cycleFor example: The running time is 15 seconds30% duty cycle 15 x [(1 - 30%) / 30%] = 35 –> The rest time will be 35 seconds 75% duty cycle 15 x [(1 - 75%) / 75%] = 5 –> The rest time will be 5 seconds If the duty cycle is higher, the rest time will be shortened, which means the starting frequency will be higher.Thermal OverloadAll actuators are equipped with thermal overload protection to guard the motor against damage due to overheating.Mechanical OverloadAll actuators are designed to withstand stall conditions. It is not recommended to subject the unit to repeated stall conditions.Explosion-Proof Electric Actuators1. DO NOT under any circumstances remove the cover of the actuator while in a hazardous location. Removal of the coverwhile in a hazardous location could cause ignition of hazardous atmospheres.2. DO NOT under any circumstances use an explosion-proof electric actuator in a hazardous location that does not meet the specifications for which the actuator was designed.3. Always verify that all electrical circuits are de-energized before opening the ac -tuator.4. Always mount and cycle test the actuator on the valve in a non-hazardous loca -tion.5. When removing the cover, care must be taken not to scratch, scar of deform the flame path of the cover and base of the actuator, since this will negate the NEMA rating of the enclosure.6. When replacing the cover, take care that the gasket is in place to assure proper clearance after the cover is secured.7. All electrical connections must be in accordance with the specifications for which the unit is being used.8. Should the unit ever require maintenance, remove from the hazardous location before attempting to work on the unit.If the actuator is in a critical application, it is advisable to have a standby unit in stock.Electric Actuators Performance Rating MAINTENANCE/REPAIRUpon final installation of the Series WE, only routine maintenance is required. The Series WE is not field serviceable and should be returned if repair is needed. Field repair should not be attempted and may void warranty.WARRANTY/RETURNRefer to “Terms and Conditions of Sale” in our catalog and on our website.

Depending on your product (number of LEDs, installed firmware, etc.) and in case the product settings have been modified with the AppBlaster tool, the information below might differ from your product configuration when in operation. In particular, the color and sequence of the LEDs on your product might be different.5.1OPERATING MODEIn order to start operating TWN4 MultiTech 2 LEGIC, it simply has to be connected directly to a host device.5.2POWER UPOnce TWN4 MultiTech 2 LEGIC is connected to the host device, it detects the type of communications cable (e.g. USB or RS-232), with which it is connected to the host.In case of RS-232:• A version string is sent via RS-232 to the host device.• A 5 V external power supply is required and must meet the following conditions:o PS2 classified power source according to IEC 62368-1o Short-circuit current < 8 A5.3ENUMERATIONThis is only applicable for the USB version: Once the device has been powered up, it is waiting for completion of the enumeration by the USB host. As long as the device is not enumerated, it is entering a minimum power consumption mode, where both LEDs are turned off.5.4INITIALIZATIONAfter powering up and enumeration (in USB mode), the device is turning on the built-in transponder reader logic. The green LED is turned on permanently. Some RFID readers need some kind of initialization, which is performed in this step. After successful initialization, the device sounds a short sequence, which consists of a lower tone followed by a higher tone.5.5NORMAL OPERATIONAs soon as the reader has completed the initialization, it is entering normal operation. During normal operation, the reader is searching for a transponder continuously.5.6DETECTION OF A TRANSPONDERIf a transponder is detected by the reader, following actions are performed:•Send the ID to the host. By default, the USB device sends by emulating keystrokes of a keyboard. An RS-232 device sends the ASCII code of an ID.•Sound a beep.•Turn off the green LED.•Blink the red LED for two seconds.•Turn on the green LED.Within the two seconds timeout, where the red LED is blinking, the transponder, which just has been recognized will not be accepted again. This prevents the reader from sending identical IDs more than one time to the host.If during the two seconds timeout of the red LED a different transponder is detected, the complete sequence restarts immediately. 5.7SUSPEND MODEThe USB version of the reader supports the USB suspend mode. If the USB host is signaling suspend via the USB bus, the reader is turning off most of its power consuming peripherals. During this operation mode, no detection of transponders is possible and all LEDs are turned off. Once the host is resuming to normal operation mode, this is also signaled via the USB bus. Therefore, the reader will resume to normal operation too.6COMPLIANCE STATEMENTS6.1EUHereby, ELATEC GmbH declares that TWN4 MultiTech 2 LEGIC is in compliance with Directive 2014/53/EU.
