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 potentiometers and other non-essential items can be helpful in the troubleshooting process. Adjustments, options, and an operational test are included in the paragraphs after the table. Preliminary Setup To prevent damage to the regulator, ensure that the regulator has been installed and connected in accordance with the installation procedures before proceeding with the system start-up. Adjust STB with no load applied. b. Check stability of governor system. c. Troubleshoot. 5. Check regulation under normal operating conditions. Poor regulation a. Check that prime mover is up to speed. b. Check that voltmeter is connected at the same point as the regulator sensing. c. Use an average sensing voltmeter (not a RMS sensing). d. Troubleshoot. 6. Reduce generator frequency. Generator output should decrease from this point. Generator output voltage does not decrease at desired frequency a. Check that all wiring is in accordance with the installation procedures b. Adjust UF control. Table 5: System startup Page 14 15 Adjustments For location of the adjustments referenced in the following paragraphs, refer to Figure 1.

Manual voltage controller models MVC-300 (if exciter field current does not exceed 7 amps) or the MVC-112 are suitable for use with the either the K65-12B or the K125-10B. Operational Test To operationally test any K65-12B or the K125-10B, perform the following steps: a. Connect the voltage regulator as shown by Figure 7, and apply 120 Vac. b. Adjust the 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 regulator operating while connected to the generator. Page 17 18 Figure 7: Operational test setup Page 18 19 Maintenance Preventive Maintenance Inspect the voltage regulator periodically to ensure that it is clean and free from accumulations of dust and moisture. Be sure that all connections are clean and tight. Troubleshooting In case of failure or defective operation of the unit, Table 6 is provided to aid in the determination of the cause and the possible solution.

Field Flashing (only for units with no PMG) When 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 the generator residual voltage is less than 6 Vac for the K65-12B or 12 Vac for the K125-10B at terminals 26 and 28, shut down the prime mover and proceed with the following steps: (1) With the prime mover at rest, apply a DC source (ungrounded), of not more than 24 Vdc, to terminals F1 (positive) and F2 (negative) in series with a limiting resistor. Use 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 approximately 10 seconds before removing the DC source. (3) If voltage build-up does not occur after performing steps (1) and (2), verify the polarity of the DC source used in steps (1) and (2) and reperform. Caution: Do not fl ash the fi eld with the generator in motion. The regulator may be damaged. Page 15 16 Stability (STB) adjustment Use an oscilloscope or other voltage-recording device 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 STB control in the clockwise (CW) direction will slow re sponse time. (2) Rotation of the 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. Voltage (VLT ADJ) adjustment (1) Installation of a jumper across terminals 4 and 7 allows the internal VLT ADJ adjustment to vary the generator nominal voltage over the operating range.

(2) Remove the jumper between terminals 4 and 7 and connect a 10k ohm external voltage adjust potentiometer across terminals 6 and 7 to allow operation of the external voltage adjust potentiometer. The internal voltage adjustment should be set fully CW for proper operation of the external adjustment. Caution: The factory calibration (FAC CAL) adjustment is intended for use by factory technicians only. The factory voltage adjust range calibration adjustment can be used if the factory calibration has been disturbed. Factory voltage adjust range calibration adjustment With the voltage regulator operating on a generator, adjust the calibration potentiometer fully ccw and the voltage adjust potentiometer fully CW. Adjust the voltage adjust CCW and verify the generator voltage is less than 90 Vac. The unit is calibrated and the calibration potentiometer can be sealed. Parallel droop (DRP) compensation Variable parallel droop compensation levels can be obtained by adjusting the droop potentiometer. CW rotation increases the amount of droop for a given condition. Options The K65-12B and the K125-10B may be equipped with the following options to enhance operational characteristics. Characteristics of these options are defined in the following paragraphs: Remote voltage adjust Connect a 10k ohm potentiometer from terminals 6 to 7, remove the jumper from terminal 4 to 7 and adjust the internal voltage adjust potentiometer fully clockwise to allow operation of a remote voltage adjust. Page 16 17 Excitation disable This option provides for disabling of the excitation system by removal of power from the voltage regulator. Manual voltage control This option provides a manual back-up channel for manually controlling the generator output during generator start-up and commissioning or in the unlikely event that the voltage regulator should fail.

Call us: 011 749 3086 Three phase or single phase sensing is standard. It boasts a compact package size with a moisture proof assembly and is mechanically very rugged like most of the Caterpillar products. It has a fast reaction time and adjustable frequency allowing variations from 45 Hertz to 65 Hertz. The VR6 AVR comes with a wide range of accessories. There is a series boost that is able to sustain the generator output at 300 rated current for a minimum of 10 seconds. A remote voltage adjust controls voltage levels with a 10 Ohm, 1 watt remotely mounted rheostat. There is a manual voltage control in case of a regulator failure. The stability adjustment allows the quickest response time to block loading while still maintaining steady state stability. Chat via Whatsapp The VR6 has been made for use with self Excited and Permanent Magnet Excited generators. This compact unit is a feedback control system that measures the output voltage of the generator. It compares the output voltage to a set point and sends a signal to adjust the excitation of the generator if any difference is found. As the excitation current in the field winding of the generator increases its terminal voltage will increase. The AVR will control current by using power electronic devices. The modern AVR uses solid state devices as opposed to the older electromechanical systems and are generally far superior in both operating efficiency and durability.
