Adjustments for Stand-alone Generators
Remove jumper wire "ST4" and turn the remote adjustment potentiometer to the center position.
Connect an analog voltmeter that is calibrated for 100 VDC on terminal "E+" and terminal "E-".
Connect a voltmeter that is calibrated for 300 VAC to 500 VAC or 1000 VAC to the output terminals of the generator.
Make sure that the "ST3" jumper wire is positioned on the desired frequency.
Turn potentiometer "P2" to a full counterclockwise position.
Turn the potentiometer "P4" to a full clockwise position.
Turn stability potentiometer "P3" counterclockwise to about 1/3 of the total rotation for the potentiometer.
Start the engine and set the engine speed to a frequency of 48 Hz for 50 Hz or 58 Hz for 60 Hz.
Adjust the output voltage to the correct value with potentiometer "P2". This voltage should be the rated voltage UN for single operation or UN plus 2% to 4% for parallel operation with a current transformer. Adjust potentiometer "P3" in both directions while you observe the voltage between "E+" and "E-". The voltage between "E+" and "E-" should be approximately 10 VDC. The best response times are obtained at the limit of the instability. Try cutting or replacing the jumper wire "ST2" if no stable position can be obtained.
Check the operation of the Load Adjustment Module (LAM). "ST5" must be jumpered. The LAM can be adjusted to 15% or 25% voltage dip by moving the "ST10" jumper wire.
Turn potentiometer "P4" slowly counterclockwise until there is a significant voltage drop. The voltage drop should be approximately 15%.
Vary the frequency around 48 Hz or 58 Hz according to the operating frequency. Check the change in the voltage that was previously observed.
Readjust the speed of the unit to the rated no-load value. Adjustments for Generators in Parallel Operation
Note: Make sure that the speed droop is identical for all of the engines before adjustments are made to the generator.
Preset the unit for parallel operation by connecting the current transformer to "S1" and "S2" of the connector "J2". Set quadrature droop potentiometer "P1" to the center position. Apply the rated load. The voltage should drop by 2% to 3%. Switch the positions of the two incoming secondary wires of the current transformer if the voltage increases.
The no-load voltages should be identical for all the generators that are intended to be run in parallel. Connect the generators in parallel. Try to obtain a 0 kW power exchange by adjusting the speed of the generator. Try to minimize the circulating currents between generators by altering the voltage setting with potentiometer "P2" or "Rhe" on one of the generators. Note: Do not change the voltage settings after this step.
Apply the available load. The setting is correct only if a reactive load is available. Equalize the kilowatts or divide the rated power of the units proportionally by altering the speed. Alter the quadrature droop potentiometer "P1" in order to equalize the currents or divide the currents. R448 Adjustment for Maximum Excitation
