34. Remove the phase B CT wires from the terminals they are connected to and
connect them to the remaining pair of CT input terminals on the Load
Sharing Module.
35. Start the engine and apply full load.
36. Measure the load signal voltage between terminals 22 and 23 and record
this voltage.
37. Shut the generator set down and reverse the phase B CT 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
these phase B CT wires to the pair of CT input terminals, in the same
polarity, that produced the most positive load signal voltage.
42. Untape and disconnect the wires from phase C CT. Connect these two
wires to the remaining pair of CT input terminals.
43. Start the engine and apply full load.
44. Measure the load signal voltage between terminals 22 and 23 and record
this voltage.
45. Shut the generator set down and reverse the phase C CT 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. Connect the phase C CT wires to the same pair of CT input terminals that
they are connected to, but in the polarity that produced the most positive
load signal voltage.
50. Label each wire with the designation of the terminal that it is now connected
to.
Load Gain Adjustment
For this procedure, the generator set must be running isochronously, not
paralleled, and with a power factor of unity (1.0 ±0.1).
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 ±0.1 Vdc.
