GENERAL DESCRIPTION●EA321 is a two phase sensed Automatic VoltageRegulator and forms part of the excitation system for a brush-less generator. Excitation power is derived from a three-phase permanent magnet generator (PMG), to isolate the AVR control circuits from the effects of nonlinear loads and to reduce radio frequency interference on the generator terminals. Sustained generator short circuit current is another feature of the PMG system. ●The AVR senses the voltage in the maingenerator winding and controls the power fed to the exciter stator and hence the main rotor to maintain the generator output voltage within the specified limits, compensating for load, speed, temperature and power factor of the generator. ●Soft start circuitry is included to provide a smoothcontrolled build up of generator output voltage.●A frequency measuring circuit continuallymonitors the shaft speed of the generator and provides under-speed protection of the excitation system by reducing the generator output voltage proportionally with speed below a pre-settable threshold. A further enhancement of this feature is an adjustable volt per Hertz slope to improve engine recovery time on turbo charged engines.Soft start circuitry is included to provide a smooth controlled build up of generator output voltage. ●Uncontrolled excitation is limited to a safe periodby internal shutdown of the AVR output device.This condition remains latched until the generator has stopped.●Provision is made for the connection of a remotevoltage trimmer, allowing the user fine control of the generator’s output.●An analogue input is provided allowingconnection to a controller or other external devices with compatible output. ●The AVR has the facility for droop CT connection,to allow parallel running with other similarly equipped generators.NOTE :1. Derate linearly from 3.7A at 50 °C to2.7A at 70 °C.2. The stated voltage regulation may not bemaintained in the presence of certain transmitted radio signals. Any change in regulation will fall within the limits in criteria B of S.EN.61000-6-2 : 2001.3. After 10 minutes.4. Applies to Mod status E onwards. Generatorde-rate may apply. Check with factory. Factory set, semi-sealed, jumper selectable.5. Any device connected to the analogue input mustbe fully looting (galvanically isolated from ground), with an insulation strength of 500V ac.6. Non condensing.3. SUMMARY OF AVR CONTROLSCONTROL FUNCTION DIRECTIONVOLT To adjust generator output voltage Clockwise increases output voltage STABILITY To prevent voltage hunting Clockwise increase the damping effect UFRO To set the UFRO knee point Clockwise reduces the knee point frequency DROOP To set the generator droop to 5% at 0pf Clockwise increases the droopTRIM To optimize analogue input sensitivity Clockwise increases the gain or sensitivity EXC To set the over excitation cut off level Clockwise increase the cut off levelDIP To set the frequency related voltage dip Clockwise increases the voltage dip DWELL To set the HZ related recovery time Clockwise increases the recovery timeI LIMIT To set the stator current limit Clockwise increases the current limit OVER V To set the over voltage trip level Clockwise increases the trip levelRAMP To set the no load voltage RAMP up time Clockwise increases the voltage ramp time RMS To set 3 phase RMS detected4. ADJUSTMENT OF AVR CONTROLS 4.1 Voltage AdjustmentThe generator output voltage is set at the factory, but can be altered by careful adjustment of the VOLT control on the AVR board, or by the external hand trimmer if fitted.Terminals 1 and 2 on the AVR will be fitted with a shorting link if no hand trimmer is required.WARNINGDo not increase the voltage above the rated generator voltage. If in doubt, refer to the rating plate mounted on the generator case. Do not ground any of the hand trimmer terminals, as these could be above earth potential. Failure to observe this could cause equipment damage.If a replacement AVR has been fitted or re-setting of the VOLT adjustment is required, proceed as follows :1. Before running generator, turn the VOLT controlfully anti-clockwise.2. Turn remote VOLT trimmer (if fitted) to midwayposition.3. Turn STABILITY control to midway position.4. Connect a suitable voltmeter (0~300V ac) acrossline to neutral of the generator.5. Start generator set, and run on no load atnominal frequency e.g. 50~53Hz or 60~63Hz. 6. If the red Light Emitting Diode (LED) isilluminated, refer to the Under Frequency Roll Off (UFRO) adjustment..7. Carefully turn VOLT control clockwise until ratedvoltage is reached.8. If instability is present at rated voltage, refer tostability adjustment, then re-adjust voltage if necessary.9. Voltage adjustment is now completed.4.2 Stability Adjustment●The AVR includes stability or damping circuit toprovide good steady state and transient performance of the generator.●A jumper link selector is provided to optimize theresponse of the stability circuit to various size generators.●The link should be positioned as shown in thediagram according to the KW rating of the generator. The correct setting of the Stability adjustment can be found by running the generator at no load and slowly turning the stability control anti-clockwise until the generator voltage starts to become unstable. The optimum or critically damped position is slightly clockwise from this point (i.e. where the machine volt are stable but close to the unstable region).4.3 Under Frequency Roll Off (UFRO)AdjustmentThe AVR incorporates an under-speed protection circuit which gives a VOLT / Hz characteristic when the generator speed falls below a presentable threshold known as the “knee” point. The red Light Emitting Diode (LED) gives indication that the UFRO circuit is operating.The UFRO adjustment is preset and sealed and only requires the selection of 50 or 60Hz and 4 pole or 6 pole, using the jumper link as shown in the diagram. For optimum setting, the LED should illuminate as the frequency falls just below nominal, i.e. 47Hz on a 50Hz system or 57Hz on a 60Hz system.4.4 DROOP AdjustmentGenerators intended for parallel operation are fitted with a quadrature droop C.T. which provides a power factor dependent signal for the AVR. The C.T. is connected to S1, S2 on the AVR, (see generator wiring diagram for details). The DROOP adjustment is normally preset in the works to give 5% voltage droop at full load zero power factors. Clockwise increases the amount of C.T. signal injected into the AVR and increases the droop with lagging power factor (cos Ø). With the control fully anti-clockwise there is no droop.4.5 Trim Adjustment●An analogue input (A1 A2) is provided to connectto the controller or other devices. It is designed to accept dc signals up to ±5 VOLT.●The dc signal applied to this input adds to theAVR sensing circuit. A1 is connected to the AVR0 VOLT. Positive on A2 increases excitation.Negative on A2 decreases excitation.●The TRIM control allows the user to adjust thesensitivity of the input. With TRIM fully anti-clockwise the externally applied signal has no effect. Clockwise it has maximum effect.●Normal setting is fully clockwise when used witha controller.WARNINGAny devices connected to this input must be fully floating and galvanically isolated from ground, with an insulation capability of 500V ac. Failure to observe this could result in equipment damage.4.6 Er Excitation (EXC) AdjustmentThis adjustment is set and sealed in the works and should not be tampered with. An over excitation condition is indicated by the illumination of the red LED which also indicates under-speed running and over-volt.The generator must be stopped to reset an over-excitation trip.4.7 DIP AdjustmentThis feature is mostly used when the generator is coupled to turbo charged engines with limited block load acceptance. The feature works by increasing the V/Hz slope to give greater voltage roll off in proportion to speed.With the DIP control fully anti-clockwise, the generator voltage will follow the normal V/Hz line as the speed falls below nominal. Turning the DIP control clockwise provides greater voltage roll off aiding engine recovery.4.8 DWELLThis feature is mostly used when the generator is coupled to turbo charged engines with limited block load acceptance. The feature works by introducing a delay between speed recovery and voltage recovery and allows a greater DIP setting without instability. With the DWELL control fully anti-clockwise, the generator voltage will follow the V/Hz line. Turning the DWELL control clockwise increase the delay time between speed recovery and voltage recovery. 4.9 Current Limit (I LIMIT) AdjustmentThis feature is mostly used to limit short circuit current or to provide a current limit on motor starting. To use this feature, current limit CT’s of the correct ratio need to be connected to the AVR S1 S2 terminals. There is an internal time limit of 10 seconds. Consult the factory before using this feature.4.10 Over Voltage (OVER V) Adjustment This adjustment is set and sealed in the works and should not be tampered with. An over voltage condition is indicated by the illumination of the red LED which also indicates under-speed running and over-excitation. The generator must be stopped to reset an over-voltage trip.4.11 RAMPThe AVR includes a soft start or voltage ramp-up circuit to control the rate of voltage build up, when the generator runs up to speed. This is normally pre-set and sealed to give a voltage ramp-up time of approximately 3 seconds. If required, this can be adjusted between the limits defined in the specification.5. FITTING AND OPERATING ( Refer to generator wiring diagram for connectiondetails )Figure 1Outline Drawing UNIT : mmATTENTION1. Leave sufficient space for the highoutput resistor to dissipate heat.Install the AVR with an up right position where the high output resistor is above heat sink.2. AVR can be mounted directly on theengine, genset, switchgear, control panel, or any position that will not affects operation. For dimension reference, please see Figure 1.3. All voltage readings are to be takenwith an average-reading voltmeter Meggers and high-potential test equipment must not be used. Use of such equipment could damage the AVR.※Use only original supplied spare protection fuse for fuse replacement.※Please accept our sincere apology if any modification in performance, specification or appearance is made without prior notice.。

SX460AUTOMATIC VOLTAGEREGULATOR (AVR)SPECIFICATION,INSTALLATION AND ADJUSTMENTSGeneral descriptionTechnical specificationSX460is a half-wave phase-controlled thyristor typeAutomatic Voltage Regulator (AVR)and forms part of the excitation system for a brush-less generator.INPUTVoltage Jumper selectable 95-132V ac or 190-264V acIn addition to regulating the generator voltage,the AVR circuitry includes under-speed and sensing loss protection features.Excitation power is derived directly from the generator terminals.Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of Frequency PhaseOUTPUTVoltage CurrentResistance50-60Hz nominal 1max 90V dc at 207V ac input continuous 4A dcIntermittent 6A for 10secs 15ohms minimumthe AVR.The AVR is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/-1.0%.REGULATION+/-1.0%(see note 1)THERMAL DRIFT0.05%per deg.C change in AVR ambient (note 2)In addition to being powered from the main stator,the AVR also derives a sample voltage from the output windings for voltage control purposes.In response to this samplevoltage,the AVR controls the power fed to the exciter field,TYPICAL SYSTEM RESPONSEAVR responseFiled current to 90%Machine Volts to 97%20ms 80ms 300msand hence the main field,to maintain the machine output voltage within the specified limits,compensating for load,speed,temperature and power factor of the generator.A frequency measuring circuit continually monitors the generator output and provides output under-speedprotection of the excitation system,by reducing the output voltage proportionally with speed below a pre-settable threshold.A manual adjustment is provided for factory setting of the under frequency roll off point,(UFRO).This can easily be changed to 50or 60Hz in the field by push-on link selection.EXTERNAL VOLTAGE

mayapply.Check with factory.Factory set,semi-sealed,jumper selectable Non condensing.DESIGN DETAILThe main functions of the AVR are:Potential Divider and Rectifier takes a proportion of the generator output voltage and attenuates it.This input chain of resistors includes the range potentiometer and hand trimmer which adjust the generator voltage.Arectifier converts the a.c.into d.c.for further processing.The Amplifier (Amp)compares the sensing voltage to the Reference Voltage and amplifies the difference (error)to provide a controlling signal for the power devices.The Ramp Generator and Level Detector and Driver infinitely control the conduction period of the Power ControlDevices and hence provides the excitation system with the required power to maintain the generator voltage within specified limits.A The Stability Circuit provides adjustable negative ac feedback to ensure good steady state and transient performance of the control system.The Synchronising circuit is used to keep the Ramp Generator and Low Hz Detector locked to the generator waveform period.The Low Pass Filter prevents distorted waveforms affecting the operation of the AVR.Power Control Devices vary the amount of exciter field current in response to the error signal produced by the Amplifier.Suppression components are included to prevent sub cycle voltage spikes damaging the AVR components and also to reduce the amount of conducted noise on the generator terminals.The Power Supply The Low Hz Detector measures the period of each electrical cycle and causes the reference voltage to be reduced approximately linearly with speed below a presettable threshold.Light Emitting Diode gives indication of underspeed running.ADJUSTMENT OF AVR CONTROLSVOLTAGE ADJUSTMENTThe generator output voltage is set at the factory,but can be altered by careful adjustment of the VOLTS control on the AVR board,or by the external hand trimmer if fitted.Terminals 1and 2on the AVR will be fitted with a shorting link if no hand trimmer is required.Terminals 3and 4are linked only for special low voltage applications.CAUTION Do not increase the voltage above the rated generator voltage.If in doubt,refer to the rating plate mounted on the generator case.CAUTION Do not ground any of the hand trimmerterminals as these could be above earth potential.Failure to observe this could cause equipment damage.If a replacement AVR has been fitted or re-setting of the VOLTS adjustment is required,proceed as follows:CAUTION1.Before running generator,turn the VOLTS control fully anti-clockwise.2.Turn remote volts trimmer (if fitted)to midway position.3.Turn STABILITY control to midway position.4.Connect a suitable voltmeter (0-300V ac)across line to neutral of the generator.5.Start generator set,and run on no load at nominal frequency e.g.50-53Hz or 60-63Hz.6.If the red Light Emitting Diode (LED)is illuminated,refer to the Under Frequency Roll Off (UFRO)adjustment.7.Carefully turn VOLTS control clockwise until rated voltage is reached.8.If instability is present at rated voltage,refer tostability adjustment,then re-adjust voltage if necessary.9.Voltage adjustment is now completed.FITTING AND OPERATINGSTABILITY ADJUSTMENTThe AVR includes a stability or damping circuit toprovide good steady state and transient performance of the generator.The correct setting can be found by running the generator at no load and slowly turning the stabilitycontrol anti-clockwise until the generator voltage starts to become unstable.The optimum or critically damped position is slightly clockwise from this point (i.e.where the machine volts are stable but close to the unstable region).UNDER FREQUENCY ROLL OFF (UFRO)ADJUSTMENTThe AVR incorporates an underspeed protection circuit which gives a volts/Hz characteristic when the generator speed falls below a presettable threshold known as the "knee"point.The red Light Emitting Diode (LED)gives indication that the UFRO circuit is operating.The UFRO adjustment is preset and sealed and only requires the selection of 50/60Hz using the jumper link.For optimum setting,the LED should illuminate as the frequency falls just below nominal,i.e.47Hz on a 50Hz system or 57Hz on a 60Hz system.。
