Installation and Operation - EuroValve

1 Installationand OperationEL Series Electric actuator VALVE AUTOMATION El electric actuators are the most advancedactuators of their type on the market today, thisachievement is due to many years of improvementand development. Basic actuators provide all thefeatures normally required for modern plantautomation and a wide range of control options areavailable to tailor actuators to individual basic Operation of El-o- matic valve actuators isthe same for all sizes. Models EL20 through EL2500feature a disengageable manual override.

2 Torqueswitches are standard on models EL100 - EL2500. A double reduction worm/worm gear system is utilizedon models EL20 to EL150. The EL200 through EL2500utilize an extra spur gear reduction on the motor shaft.

3 ELECTRICAL WIRINGThe control circuitry feeding the actuator must not allowpower to be supplied to both open and close motorwindings at the same instance in time. For example,when power is applied to the open terminal, the close terminal must be isolated from the power supplyand vice versa. Failure to do so will result in the several actuators are controlled from a commoncontrol switch, which has only a type electricalcontact on it, then the result can be that the actuatorswill run in different example: An open/stop/close switch with contacts on it controls three actuators.

4 Whenthe switch is turned to the open control position, allthree actuators will start to run open. If any one of thethree actuators reaches its open position before theother two it can receive power via the common and the other actuators close motor winding,resulting in that actuator running several actuators are required to be controlled inparallel with one 3-position switch, that switch musthave separate contacts for each actuator :1. Use wire with proper gauge and insulation. (followstandards prescribed by the relevant electricalcode) 2.

5 actuator chassis must be correctly Use appropriate conduit or cable glands for weatherproof or explosion proof applications. 4. Follow the wiring diagram to ensure properconnection of power and control voltage to theactuator. 5. Make all splices or connections using the correctpin connector or terminal strip. 6. Always connect anti condensation heater. STORAGEW arehouse Storage1. Actuators should be stored in a clean, drywarehouse free from excessive vibration and rapidtemperature change. 2. Actuators should not be stored on any floor In areas of high humidity the actuator should have apacket of desiccant placed in the motorcompartment.

6 (this will absorb excessive moisture) On Site Storage1. Actuators should be stored in a clean, dry locationfree from excessive vibration and rapid temperaturechange. 2. Ensure all actuator covers are in place and If power is not available, place a packet of desiccantin the motor compartment. (replace cover andsecurely fasten) 4. Replace plastic conduit plugs with appropriate pipeplugs. Failure to follow proper storage guidelines will voidwarranty. DO1. Keep motor compartment clean and dry. 2. When applicable connect the compartment heater.

7 (not fitted on EL20) 3. Check unit wiring and ensure it coincides with theproper wiring diagram. 4. Power supply should be free from excessive voltagetransients (spikes).5. Control lines should be shielded properly. 6. CAUTION: Shut off incoming power beforeinstalling or repairing any electrical device. 7. Check motor nameplate to be certain that theactuator voltage is the same as your incomingvoltage. 8. Schedule a periodic maintenance check of all El-O- matic actuators to prolong life and ensure properperformance. (we suggest check for correctopening and closing once a month) 9.

8 Set open and close limit switches manually, inaccordance with instructions. (see page 19) 10. Be sure and lubricate unit during reassembly. (seeLUBRICATION) 11. Check limit switch setting prior to motor Operation ifthe actuator has been repaired or disassembled. DON CAUTION: Do not attempt to install or repair anyelectric device without shutting off incoming power. 2. Do not operate valve without first setting limitswitches and checking direction of motor rotation. 3. Release torque before disassembling gear traincomponents or the actuator from the Do not adjust torque switch settings.

9 (these arefactory set and need no adjustment) 5. Do not use a cheater or extension bar on thehandwheel. (this could result in damage to the valveassembly or cause physical injury) 6. Do not alternately start and stop motor to seat orun-seat a valve. If properly sized, the runningtorque of the actuator should seat the valve innormal Operation . Installation3 LUBRICATION El-O- matic utilizes a totally sealed and permanentlylubricated gear case. The actuator can be mounted inany position. It is not unusual to find a very smallamount of lubricant weeping around shaft seals.

10 Thissituation can occur during long periods of storage. Thislubrication will not affect Operation and should simply bewiped up with a clean cloth. Once equipment hasbegun operating, this weeping should disappear. The actuator gearbox is filled with FINA CERAN M (MO S2). This standard lubricant has been provenextremely reliable. Should the gearbox bedisassembled, repack with EP370 or any good qualitymineral based gear DROPPING POINT: > 300 : Calcium :NLGI Class and QTY. 24 ScrewSteel 31 Terminal Block 41 Marking Tag 52 ScrewSteel 61 CoverSteel 71 Capacitor 81O-Ring 91 HousingAluminium 101 Limitswitch CamAluminium 111 Motor Support PlateSteel 121 Drive Sleeve BearingSteel 131 PinSteel 141 SpringSteel 151O-RingBuna 161 Top Bearing Steel 174 ScrewSteel 1811 LockwasherSteel 191 Limitswitch CamAluminium 207 Hex NutSteel 211 Terminal BracketSteel 222 BlindstopBronze 234 ScrewSteel 249 Lock WasherSteel 255 ScrewSteel 265 Isolation Plate 274 Micro Switch 282 ScrewSteel 292 Lock WasherSteel 301 Limitswitch
