7. om water moisture or oil Away from flammable substances Secure and have no risk of falling FREE FROM MUCH VIBRATION As much as possible do not install it in the generator housing if the generator vibrates too much d Avoid direct contact of the circuit board with any metal part of the generator Reg 6 has a mounting prop installed on it which isolates the circuit board Do not remove it during installation Summit Systems REGMASTER AVR Limited e Avoid overloading the generating set as overloading can damage any AVR f Avoid erratic engine speed adjustment as this can damage any AVR B WIRING DIAGRAM AND INSTALLATION STEPS STAB Stability Adjustment Knob VOLT Voltage Adjustment Knob N Neutral L Live X Positive Exciter XX Negative Exciter INSTALLATION TOOLS i Functional Digital or Analog Multimeter ii Frequency meter or Tachometer for measuring engine speed iii Precision screw drivers for voltage and stability adjustment iv A generator technician should own a complete toolbox INSTALLATION STEPS 1 Make sure that the generator set is intact That is to say that the set starts and runs smoothly and the speed governor is working fine ii Use a digital multimeter digital meters are more precise and accurate than analog meters set at 200 Q resistance to measure the resistance of the exciter coil X and XX winding terminals
8. ut voltage frequency is okay POSSIBLE FAULT CAUSES REMEDY No power output in generator Connecting cables to AVR terminals are detached The generator circuit breaker tripped off Flying diodes in Check and confirm AVR connections Use battery to excite the generator If there is still no output voltage check the flying diodes exciter and field coils of the alternator If battery excitation produces an output AVR is faulty or is not properly connected generator alternator are faulty The AVR is faulty The alternator coils are faulty Check connections again or repair replace the AVR Summit tem Seen REGMASTER AVR Limited Power output Generator engine speed is Increase speed of generator engine frequency of low below 1500 RPM until the desired 50 Hz frequency is generator is low Frequency of generator reached Some sensitive equipment below 50 Hz output can only be such as split system air conditioners changed or altered by color photograph printers and varying the engine processing machines photocopiers speed UPS equipment computers and modern instruments are frequency sensitive If the voltage is full and frequency is low such equipment may not function Increase the generator speed to increase the frequency of the output If frequency is to be 50 Hz at full load ensure that the no load frequency is up to 51 or 52 Hz so that
9. y continue to adjust generator terminal voltage using the VOLT knob until the desired voltage 220 240 volts Phase to Neutral or 380 415 volts Phase to Phase is reached Make sure you use a multimeter during this adjustment because the generator panel meter can deceive you with a wrong reading if it is faulty If power flickers or is unstable slightly reduce the voltage and gradually increase the stability using the STAB knob until power becomes stable Then adjust and set the voltage BATTERY EXCITATION OR FLASHING Summit Systems REGMASTER AVR Limited After installing Reg 6 if the AVR does not build up voltage it could be that the generator field winding has lost the residual magnetism required to produce the necessary initial voltage for the AVR to build up and regulate voltage This problem can be solved by using battery excitation There are two ways to do it Battery excitation with AVR disconnected Completely disconnect REG 6 from the generator and connect a 12 or 24 volts battery depending on the battery the generator uses to the exciter terminals Connect X of generator exciter to the positive of the battery and the XX of generator exciter to the negative of the battery Start the generator and make sure that the generator terminal voltage has built up from the battery With the battery still connected VERY IMPORTANT stop the generator Then disconnect the battery from
