4. Disconnect the phase C CT wires from terminals 8 and 9. Connect and tape
these two wires together as in Step 3.
5. Connect the two wires from the phase A CT to the phase A input terminals 4
and 5.
6. Start the prime mover, apply full load, and monitor the load sensor output.
Start a list and record this value.
7. Unload the system and reverse the phase A CT wires on terminals 4 and 5.*
8. Apply full load, monitor the load sensor, and record this value.
9. Unload the system, remove phase A CT wires from terminals 4 and 5, and
connect them to phase B input terminals 6 and 7.*
10. Apply full load, monitor the load sensor, and record this value.
11. Unload the system and reverse the phase A CT wires on terminals 6 and 7.*
12. Apply full load, monitor the load signal, and record this value.
13. Unload the system, remove phase A CT wires from terminals 6 and 7, and
connect them to phase C input terminals 8 and 9.*
14. Apply full load, monitor the load sensor, and record this value.
15. Unload the system and reverse the phase A CT wires on terminals 8 and 9.*
16. Apply full load, measure the load signal, and record this reading.
17. Unload the system and compare the six readings taken.*
18. Remove the phase A CT wires from terminal 8 and 9 and connect the phase
A wires to the pair of terminals that produced the highest positive load value
and in the polarity that produced the highest positive load value.
19. Untape and disconnect the phase B CT wires. Connect the phase B CT wires
to one pair of the two remaining pairs of CT input terminals on the load
sensor.
20. Apply full load and measure the load signal. Start a new list and record this
reading.
21. Unload the system, and reverse the phase B CT wires on the same
terminals.*
22. Apply full load, measure the load signal, and record this reading.
23. Unload the system, remove phase B CT wires, and connect them to the other
pair of terminals.*
24. Apply full load, measure the load signal, and record this reading.
25. Unload the system and reverse phase B CT wires on the same terminals.*
26. Apply full load and measure the load signal. Record this reading, and
compare the four readings on the list.
27. Unload the system. Remove the phase B CT wires and connect them to the
pair of CT input terminals that produced the highest positive load signal
reading and with the polarity that produced the highest positive load signal
reading.*
28. Untape and disconnect the phase C CT wires. Connect these two wires to
the remaining pair of CT input terminals.
29. Apply full load, measure the load signal, and record this reading.
30. Unload the system and reverse the phase C CT wires on the same
terminals.*
31. Apply full load, measure the load signal, and record this reading.
32. Unload and shut down the system. Compare the two readings.*
33. Connect the phase C CT wires to the same pair of CT input terminals, but in
the polarity that produced the highest positive load signal reading.
34. Re-label each wire with the phase designation of the terminal that it is now
connected to.
35. Remove the burden resistors and terminal block.
