12-8. ELECTRICAL ACCESSORIES INSPECTION.
a.
Check all cable and harness assemblies for secure fastening and protection against chafing and vibration.
b.
Ensure that all cable and harness connectors are firmly secured in their proper place.
c.
Check Annunciator Alarm System.
(1)
Press the ANNUNCIATOR TEST pushbutton Si5 located below the annunciator panel. The alarm
shall sound, and all annunciator lamps shall light. Releasing the test button shall silence the alarm,
and turn off the lamps.
(2)
If the alarm fails to sound, or all lamps do not light, repair the system in accordance with Chapter 10.
SECTION IV. OPERATIONAL TEST
12-9. GENERAL
a.
The tests described in this section require generator set operation and provide verification of generator set
performance characteristics.
NOTE
All tests shall be conducted with the 2400/4160 volt connections, unless otherwise specified.
b.
Unless otherwise specified, all test instrumentation will be certified accurate and maintained in accordance
with MIL-STD-705. Figure 12-3 shows the test instrumentation hookup to be used for individual
instruments.
c.
Temperatures will be measured by thermocouples and properly calibrated meters. Barometric pressures
will be measured by a mercurial barometer corrected for temperature, vapor pressure, and altitude.
Aneroid barometers shall not be used.
d.
Generator set operation shall be in accordance with the Operator and Organizational Maintenance Manual.
e.
All test results shall be logged on the appropriate form as required.
CAUTION
Before performing any of the operating tests listed In Figure 12-3, ensure that the generator
set Is serviced with the correct fuel, oil, and coolant as listed on the data plate.
f.
Perfom the operating tests as indicated in Table 12-3.
12-10. MALFUNCTION INDICATOR AND INSTRUMENTS.
a.
The malfunction indicator system is electrically isolated and independent of the protection system. Testing of
the indicators can be accomplished at the same time that the protective devices are tested in tests 11,
12,13,14,15,16, 17, 19, 20, and of Table 12-3.
b.
In the event that one of the indicator circuits does not work, verify that the lamp is functional by operating the
ANNUNCIATOR TEST push-button S15 located on the generator panel (see paragraph 12-8, step c).
c. During the full load stabilization periods of the following test procedures, record the readings of both the test
meters, and the generator set Meters for the highest and lowest readings obtained. At the conclusion of the
test, calculate the accuracy of the generator set instruments using the following formula:
SET
TEST
ACCURACY=
METER METER X 100
SET METER
FULL SCALE VALUE
The above procedure shall be repeated for measurements on the remote control module.
