NOTE
Polarity of signal between J9-8 and J9-11 must be correct. Check wiring polarity at
current transformer in output box prior to test.
(9)
Start generator set, paragraph 2.11.1.
NOTE
Polarity of signal between P9-8 and P9-11 must be correct. Check wiring polarity at
current transformer in output box prior to test. Refer to Schematic FO-1.
(10) Connect multimeter leads to P24-5 and P9-8. At full load, reading should be approximately 4 VAC.
At no load, the reading should be approximately 0 VAC. If either of these readings are different,
replace backplane module (20).
(11) Disconnect multimeter leads from P24-5 and P9-8.
(12) Shut down generator set, paragraph 2.11.2.
(13) Install DCS control box top panel, paragraph 4.7.2.
