Procedure

  1. 1. If normal “Utility” source voltage is indicated but
  2. retranster does not occur, go to Test 14.
  3. 2. If normal “Utility” source voltage is available but
  4. generator starts in automatic mode, go to Test 5.
  5. 3. If “Utility” voltage is NOT indicated, find cause of
  6. problem and correct.
  7. Test 14- Check Voltage at Terminals
  8. Al/A2
  9. 1. See Test 1 on Page 5.4-1. Campiete Steps 1 through
  10. 7 of that test. The generator should crank and start.
  11. Transfer to the “Standby” power supply should occur.
  12. 2. Camplete Step 8 of Test 1. Retransferback to "Utility"
  13. should occur, followed by generator shutdown.
  14. 3. If retransfer does NOT occur, use an AC voltmeter
  15. (or a VOM) to check for correct “Utility” source voltage
  16. at terminals A1/A2. .
  17. RESULTS:
  18. 1. If “Utility” source voltage is NOT indicated, go to Test
  19. 4
  20. 2. if voltage reading is good but retransfer does NOT

Tools required

  • 4. Check voltage across monitor socket terminal 8 and
  • Figure 12. 3-Phase Power Monitor and Socket
  • 3. Check line-to-line voltage across monitor socket
