(1) Place T-R current limiting switch in OFF position. Thk will eliminate the
soft start feature of the T-R, but will prevent AC voltage from dropping low
enough to trip the AC load contactar.
(2) Line-drop compensation on the T-R must be REDUCED or turned.DOWN
completely to prevent opening of the AC load contactor by an overvoltage
condition.
Readjust T-R line-drop compensation so that AC voltage (as
indicated by the generator set voltmeter) does not exceed 118-V AC when
the DC toad is 500 Amperes.
If higher DC voltage is needed, adjust T-K
line-drop compensation as required. Observe AC voltage while making
this adjustment to be certain that it does not go TOO H IGH with DC load.
(3) During simultaneous, continuous operation, foods on either circuit are
limited mly by the capacities of their respective circuits, however, the
combined loads should not exceed the rated capacity of the generator set
(90 WA cf 72 W).
0. Simultaneous 35-V DC a 112-V DC and 115-V AC Power Delivery
Since no ither of these T-Rs have line-drop compensation capabilify, no special
adjustment to the T-R will be required.
Combined loads shculd not exceed the
rated capacity of the generator set (90 KVA OT 72 Kw).

24 Volt DC Power Supply
.
This power supply is furnished with generator set 5359&q; U NLY. .It is to be
used ONLY on aircraft which require a 24 volt DC signal standing on power receptacle
pin E as a condition for receiving 115 volt AC, 400 Hz ground power.
To operate the power supply, position the power supply switch (42, Fig. 1) to UP
position BEFORE closing load contactor for nonal pChrJer delivery.
CAUTION: DO NOT USE THIS POWER SUPPLY ON F-4 OR F-15 AIRCRAFT.
ETISE, DAMAGE TO AIRCRAFT ON-BCJARD EQUIPMENT
WILL RESULT.
