Figure 3-1. Temporary CT Connections3. Disconnect the phase "B" CT wires from terminals 6 and 7 and connect these two wires together. Use a small screw and nut and tape the connection.4. Disconnect the phase "C" CT wires from terminals 8 and 9 and connect these two wires together. Use a small screw and nut and tape the connection.5. Connect the two wires from the phase "A" CT to phase "A" input terminals 4 and 5.
- START-UPBe prepared to make an emergency shutdown when starting the engine, turbine, or other type of prime mover, to protect against runaway or overspeed with possible personal injury, loss of life, or property damage.
6. Start the engine and apply full load.7. Measure the load signal voltage between terminals 22 and 23 and record this voltage.8. Shut the generator set down and reverse the phase "A" wires on terminals 4 and 5.9. Start the engine and apply full load.10. Measure the load signal voltage between terminals 22 and 23 and record this voltage.11. Shut the generator set down.12. Remove the phase "A" CT wires from terminals 4 and 5 and connect the phase "A" CT wires to phase "B" input terminals 6 and 7.13. Start the engine and apply full load.14. Measure the load signal voltage between terminals 22 and 23 and record this voltage.15. Shut the generator set down and reverse the phase "A" CT wires on terminals 6 and 7.16. Start the engine and apply full load.17. Measure the load signal voltage between terminals 22 and 23 and record this voltage.18. Shut the generator set down.19. Remove the phase "A" CT wires from terminals 6 and 7 and connect the phase "A" CT wires to phase "C" input terminals 8 and 9.20. Start the engine and apply full load.21. Measure the load signal voltage between terminals 22 and 23 and record this voltage.22. Shut the generator set down and reverse the phase "A" wires on terminals 8 and 9.23. Start the engine and apply full load.24. Measure the load signal voltage between terminals 22 and 23 and record this voltage.25. Shut down the generator set.26. Remove the phase "A" CT wires from terminals 8 and 9 and connect the wires to the pair of terminals, in the same polarity, that produced the most positive load signal voltage.27. Untape and disconnect the Phase "B" CT wires. Connect the phase "B" CT wires to one pair of the two of the two remaining CT input terminals on the Load Sharing Module.28. Start the generator set and apply full load.29. Measure the load signal voltage at terminals 22 and 23 and record this voltage.30. Shut the generator set down and reverse the phase "B" wires on the CT input terminals.31. Start the engine and apply full load.32. Measure the load signal voltage between terminals 22 and 23 and record this voltage.33. Shut down the generator set.34. Remove the phase "B" CT wires from the terminals they are connected to and connect them to the
