MIL-DTL-38195D
4.4.1.2.8 Braking systems test. The dead-man system shall be tested on relatively level ground to demonstrate
that the brakes will be properly applied upon release of the draw bar. The parking brake shall be tested to
demonstrate that it will hold the generator set on a 6 percent grade (see 3.17; 4.2; 4.5.1; and Table V Test 29).
4.4.1.2.9 Rated load test. Rated loads shall be as follows:
a. Bleed Air As corrected for sea level and 59° F; 147 +5/-0 pounds per minute and 48 ± 2 psi
@ 385° F minimum.
AC 60 kW @ 0.8 PF, 3 Phase, 4 wire, 120/208 volts ± 1 percent (steady state), 400 Hz ±
b.
0.25%.
DC 200 amperes @ 28 ± 1.5 volts; at no time shall output voltage exceed 29.5 volts.
c.
4.4.1.2.10 Battery charger test. The battery charging circuit shall be checked for proper operation. Charging rate
shall he at least 15 amperes when observed immediately following engine start-up (see 3.9.1.1.1; 4.2; and 4.5.1).
4.4.1.2.11 Remote control circuit test. Using the remote control receptacle (J34) mounted externally on the front
of the set enclosure, it shall be demonstrated that the "bleed-air" system can be controlled remotely. A test circuit
(see Figure 1) shall be connected to J34 receptacle and the set operated as follows (see 3.11.5; 4.2; and 4.5.1):
a.
Verify that the MASTER switch (S5) and BLEED AIR switch (S10) on the generator set
instrument panel are in the OFF position.
b.
Verify that all switches on the remote control test panel (see Figure 1) are in the OFF position.
c.
Connect remote test circuit (see Figure 1) into receptacle J34.
d.
Place remote MASTER switch (S5R) in the "ON" position, remote battery power indicator
(DS2R) should light.
e.
Close momentary remote TURBINE START switch (S7R); cranking cycle should be initiated;
cranking cycle indicator (DS3R) should light and remain lighted until turbine accelerates to
starter trip-out speed (35%); turbine should accelerate through 95 percent speed and remote
READY-TO-LOAD indicator (DSICR) should light.
f.
Place AC CONTACTOR switch (S3) on set panel in the momentary RESET position.
g.
Place remote BLEED AIR switch (S10R) in the ON position: bleed air solenoid valves should
actuate to permit flow of bleed air through the flexible duct.
h.
Place remote BLEED AIR switch (S10R) in the OFF position; air solenoid valves should close
and stop flow of bleed air in duct.
i.
Place remote MASTER switch (S5R) in the OFF position; READY-TO-LOAD indicator light
should go out as turbine rolls to a stop.
j.
Repeat steps "d" through "i" two more times.
4.5 Test schedules. The test schedules shall be as shown in Table V. Non-conformance to the applicable
requirement paragraph shown in Column E of the schedules shall constitute failure of this test and rejection of the
generator, the generator with excitation system, or the set, as applicable. The Government reserves the right to reject
the equipment for not meeting any requirement herein, even though not performing a test directly related to the
specific requirement. The requirements in Section 3 shall apply to another test.
