35. Start the generator set and apply full load.
36. Measure the load signal at terminals 22 and 23 and record this voltage.
37. Shut the generator set down and reverse the phase “B” wires on the CT
input terminals.
38. Start the engine and apply full load.
39. Measure the load signal voltage between terminals 22 and 23 and record
this voltage.
40. Shut down the generator set.
41. Remove the phase “B” CT wires from the CT input terminals and connect
the wires to the pair of terminals, in the same polarity, that produced the
most positive load signal voltage.
42. Untape and disconnect the Phase “C” CT wires. Connect the phase “C” CT
wires to remaining pair of CT input terminals on the Load Sharing Module.
43. Start the generator set and apply full load.
44. Measure the load signal voltage at terminals 22 and 23 and record this
voltage.
45. Shut the generator set down and reverse the phase “C” wires on the CT
input terminals.
46. Start the engine and apply full load.
47. Measure the load signal voltage between terminals 22 and 23 and record
this voltage.
48. Shut down the generator set.
49. Remove the phase “C” CT wires from the CT input terminals and connect
the wires to the pair of terminals, in the same polarity that produced the
most positive load signal voltage.
50. Label each wire with the designation of the terminal to which it is now
connected. Be sure and remove the original designations to avoid future
confusion.
Load Gain Adjustment
For this procedure, the generator set must be running isochronously, not
paralleled, and with a power factor greater than 0.8.
1. Start the generator set and run at full load.
2. Measure the load signal voltage and adjust the LOAD GAIN potentiometer
for 6 ± 0.1 Vdc.
If the load signal voltage cannot be raised to 6 volts, and the phasing has been
checked and is correct, it will be necessary to use a lower load signal voltage. Set
the full load signal voltages of all generator sets in the system to the same voltage.
