TM 9-6115-604-34NAVFAC P-8-633-34Figure 10-12. Power Factor Transducer PFR, On Equipment Test Setup(4)Using AMMETER switch S114 and AC AMPERES meter Ml02, verify an indication of 127 to 133 amperesfor each phase of generator GI output.(a) Proper AC AMPERES indications mean watt transducer WMT is receiving correct current input from current transformers CT1 2, CT11, and CT1 0. If indications are OK, proceed with step (5), below.(b) If the AC AMPERES indication is out of the specified range, then there is some other element in circuit with watt transducer WMT that is causing the problem, and this test is over. Test and troubleshoot as required.(5)Open upper cabinet B door.(6)Using an AC voltmeter with insulated leads, check voltage between watt transducer WMT terminals 4 and12A and between WMT terminals 5 and 6. Verify that voltage is 119 to 121 V ac across each terminalpair.(a) Proper voltage indication means watt transducer WMT is receiving correct ac voltage inputs from transformers T104 and T105. If indications are satisfactory, proceed with step (7), below.(b) If ac voltage inputs are out of range, then there is some other element in circuit with watt transducer WMT that is causing the problem, and this test is over. Test and troubleshoot as required.(7)Shut down the generator set in accordance with the Operator and Organizational Maintenance Manual.10-24
