Regulator damage may result.CAUTIONThe factory calibration (FAC CAL)adjustment is intended for use by factory technicians only. The following procedure can be used if the factory calibration has been disturbed.Table 2. Internal AdjustmentsAdjust. Adjustment.Description DRP Voltage Droop Adjust FAC CAL FAC CAL is a factory voltageadjust range calibration. No customer adjustment is required.VLT ADJ Multi-Turn Voltage Adjust UF Underfrequency Knee Adjust STB Stability Adjust OPERATION GeneralTable 3 provides system start-up procedures for the AVC63-12 and AVC125-10 Voltage Reg-ulators. Symptoms of problems occurring during start-up that arise from incorrect regulator adjustment and certain generator system problems that resemble faulty regulation are included together with possible solutions. Simplifying the system by eliminating components, such as remote adjust poten-tiometers and other non-essential items can be helpful in the troubleshooting process. Ad-justments, options, and an operational test are included in the paragraphs after the table.Preliminary Set-UpTo prevent damage to the regulator, ensure that the regulator has been installed and connected in accordance with the paragraphs in Instal-lation and Connections before proceeding with the system start-up. System Start-UpRefer to Table 3 for system start-up.ADJUSTMENTS Field FlashingWhen the regulator is operated with the generator for the first time, the polarity of the residual magnetism may not be correct or of sufficient magnitude. If generator residual voltage is less than 6 Vac for the AVC63-12 or 12 Vac for the AVC125-10 at terminals 26,28and/or 30 shut down the prime mover and proceed with the following steps:1.With the prime mover at rest, apply a dcsource (ungrounded), of not more than 24Vdc, to terminals F1 (positive) and F2(negative) in series with a limiting e one (1) ohm of resistance for each volt from the dc power source with a power rating of least one (1) watt per ohm.EXAMPLE: If using a 24 Vdc source, use a 24-ohm, 24-watt resistor.2.Allow the field to be flashed for approx-imately ten seconds before removing the dc source.3.If voltage build-up does not occur afterperforming steps (1) and (2), verify the polarity of the dc source used in steps (1)and (2) and re-perform.Frequency Roll-Off (UF Knee) Adjustment The underfrequency knee (roll-off) is typically set below the nominal system frequencies.When the generators speed falls below the knee set point of the regulator, generatorvoltage is reduce proportional to the speed of the machine. To adjust the underfrequency knee, follow the steps below:(1)Adjust the generator frequency for nominal frequency (50, 60, or 400 Hz).(2)Adjust the underfrequency potentiometer (UF) CCW.(3)Adjust the Voltage Adjust potentiometer for nominal generator voltage.(4)Adjust the underfrequency potentiometer (UF) CW until the voltage begins to decrease.(5)Adjust the underfrequency potentiometer (UF) CCW until the voltage just returns to the value set in Step 3.(6)The underfrequency knee is now set just below the nominal operating frequency. Further rotation in the CCW direction will lower the knee frequency set point at which underfrequency compensation begins.(7)Connecting a jumper from terminal 8 to terminal 6a will provide an underfrequency slope of 1 P.U. V/Hz. No connection to terminal 8 will result in an underfrequency slope of 2 P.U. V/Hz. The slope can also be selected on the 400Hz models. However, the actual V/Hz curve is approximately 1 P.U. or 2 P.U.depending if the terminal 8 is jumpered to 6a or not.Stability (STB) AdjustmentAn oscilloscope or other voltage-recording device should be used if an optimal stability setting is desired. Adjust the stability setting with the generator at no load. Good response can be obtained with the following procedure.(1)Rotation of the front panel STB control in the clockwise (CW) direction will slow response time.(2)Rotation of the front panel STB control in the counter-clockwise (CCW) direction will speed response time. If rotated too far CCW,the generator voltage may oscillate (hunt).(3)Rotate the front panel STB control CCW until the system just begins to oscillate and then rotate CW just past the point where oscillation occurred. Apply various amounts of loads to determine proper stability performance.Voltage (VLT ADJ) Adjustment(1)Installation of a jumper across terminals 4and 7 allows the internal (front panel) VLT ADJ adjustment to vary the generator nominal voltage over the operating range.(2)Remove the jumper between terminals 4and 7 and connect a 10k ohm external voltage adjust potentiometer across terminals 6a and 7to allow operation of the external voltage adjust potentiometer. The internal voltage adjustment should be set fully CW for proper operation of the external adjustment. It should be noted, as the external potentiometer resistance in-creases, generator voltage also increases.Factory Calibration (FAC CAL) Adjustment(1)With the voltage regulator operating on a generator, adjust the calibration potentiometerfully CCW and the external voltage adjust potentiometer fully CW. Adjust the FAC CAL potentiometer CW until the generator voltage reaches the desired maximum voltage setting.The unit is calibrated and the calibration potentiometer can be sealed. Parallel Droop CompensationVariable parallel droop compensation levels can be obtained by adjusting the droop poten-tiometer. CW rotation increases the amount of droop for a given condition.Line Drop CompensationWhen the sensing input CT connections are swapped to provide LDC, the droop adjustment becomes the LDC adjustment.OPTIONSThe AVC63-12 and AVC125-10 may be equipped with the following options to enhance operational characteristics. Characteristics of these options are defined in the following para-graphs.Remote Voltage AdjustConnect a 10 k ohm, 2 watt potentiometer from terminals 6a to 7, remove the jumper from terminal 4 to 7 and adjust the internal voltage adjust potentiometer fully CW to allow operation of a remote voltage adjust.Inrush Current Reduction ModuleAn ICRM-15 (Inrush Current Reduction Module) is required when energizing the AVC63-12 and AVC125-10 from a source that is already at the regulators input power ratings.This module minimizes the amount of inrush current that could be seen when power is applied.Excitation DisableThis option provides for disabling of the excitation system by removal of power from the voltage regulator. A switch removing voltage from terminals 26, 28 and/or 30 will remove power.Excitation LimiterThis EL200 option provides an initial fast acting limit of the field current at a pre-selected level.Once the field current has changed to the selected level, the output provides a signal to the regulator to change the excitation.Var/PF ControlThis option allows the AVC63-12 and the AVC125-10 to regulate the var and power factor while the generator is connected to an infinite or utility bus. The var/PF option (Model Number SCP250G-50 for 50-hertz operation or SCP250G-60 for 60-hertz operation) supplies a dc signal into the AVC63-12 and AVC125-10terminals 2 and 3 to regulate the SCP250 var or power factor setting. (See Figure 7 for inter-connection diagram.)Current Boost SystemWith this CBS212 option, if the generator output voltage drops below the preset operation point due to a short or large motor starting, the current boost function detects the voltage drop.The function then provides full current boost to the generator exciter until the voltage returns to a level just above the operation point.Manual Voltage ControlThis option provides a manual back-upchannel for manually controlling the generator output during generator start-up and commissioning orin the unlikely event that the voltage regulator should fail. Manual voltage controller model MVC-112 is suitable for use with either the AVC63-12 or the AVC125-10 voltage regulator.Table 3.

System Start-Up (Continued)6.Reduce generator frequency. Generator output should decrease from this point.If the generator output voltage does not decrease at desired frequency:a.Check that all the wiring is inaccordance with the connection diagrams provided in these instructions.b.Adjust FREQ control.OPERATIONAL TESTThis test is designed to test all eight models of the AVC63-12 and AVC125-10. See Table 4for appropriate testing voltages and frequencies.To operationally test any AVC63-12 or AVC125-10, perform the following steps.a.Connect the voltage regulator as shown by Figure 9 and apply appropriate voltages.b.Adjust the front panel VLT ADJ control fully counterclockwise (CCW).RESULT: Observe that the lamp is OFF.c.Adjust the front panel VLT ADJ control clockwise (CW).RESULT : Observe that the lamp is now ON.d.Adjust the front panel VLT ADJ control until the lamp just goes out.Regulator operation is satisfactory if the above results are obtained. Stability, however, must be tested with the generator and regulator in operation.MAINTENANCEPreventive MaintenanceA periodic inspection should be made of the voltage regulator to ensure that it is clean and free from accumulations of dust and moisture. Be sure that all connections are clean and tight.TroubleshootingIn case of failure/defective operation of the unit, simplifying the system by eliminating com-ponents, such as remote adjustpotentiometers and other non-essential items can be helpful in the troubleshooting process.Table 4.

Install an air dryer if water condensation could havea detrimental effect on the application.WARNINGThese products are intended for use in industrialcompressed air systems only. Do not use these productswhere pressures and temperatures can exceed those listedunder Technical Data.Polycarbonate plastic bowls can be damaged andpossibly burst if exposed to such substances as certainsolvents, strong alkalies, compressor oils containing ester-based additives or synthetic oils. Fumes of thesesubstances in contact with the polycarbonate bowl,externally or internally, can also result in damage. Cleanwith warm water only.Use metal bowl in applications where a plastic bowlmight be exposed to substances that are incompatible withpolycarbonate.If outlet pressure in excess of the filter/regulatorpressure setting could cause downstream equipment torupture or malfunction, install a pressure relief devicedownstream of the filter/regulator. The relief pressure andflow capacity of the relief device must satisfy systemrequirements.The accuracy of the indication of pressure gauges canchange, both during shipment (despite care in packaging)and during the service life. If a pressure gauge is to beused with these products and if inaccurate indications maybe hazardous to personnel or property, the gauge should becalibrated before initial installation and at regular intervalsduring use.Before using these products with fluids other than air,for non industrial applications, or for life-support systemsconsult Norgren.。
