(b)
Check the transformer output voltage by setting the voltage wafer
selector switch to 115VAC (-115 B), and the voltmeter should read
115 V.
Test AC generator No. 2 and the transformer proceeding in the
simiiarway.
(c)
Test the induction-type pressure gauges installed on the center
control pedestal when powered by the standby transformer .QlI1M.
With the TRANSF .QlI1M MAIN - STBY (TPAHC<l>. .QlI1M. OCHOBH -
3AnACH) selector switch set to STBY (3AnACH), the induction-
type pressure gauges indicate pressure.
(d)
Check the serviceability of the rectifiers:
Switch the generators NN1&2 on by setting the generator NN1&2
switches to ON position.
Set the selector switch, located on the DC switch panel situated on
the RH side panel of the electric switch panel, to RECT BUS posi-
tion.
Check the DC electrical system voltage by setting alternately the
RECTIFIERS
1,11,111
switches, located on the DC switch panel, to ON
position; the voltmeter, located on the switch panel of the electric
switch panel, should indicate 27-29 V.
Switch the BY-6 rectifiers NN1,2,3 on
Set the selector switch to BATT BUS position: the voltmeter should
indicate 27-29V
Note: If the voltmeter indicates 24 V, the BAn annunciator is on
and the ammeters indicate the discharge current (the pointer
is to the right from "0"), this means that the rectifier bus is not
connected to the battery bus (.QMP-200.Q failure).
Note. Test the AC generators with the ground AC power source dis-
connected, since the AC generators will not cut in with the
ground AC power source connected.
(17) If icing is anticipated in the next flight the Captain should order the Flight
Engineer to test the anti-icing systems as instructed in Section 7.
(18) If the anticipated flight does not involve fulfillment of extremely urgent
task, after testing the engine, order the Flight Engineer to switch off all
the electrical loads except for the power plant instruments, turn the throt-
tle control twist grip fully to the left, cool down the engines at idle for 1 to
2 min in summer and 2 to 3 min in winter. Prior to shut down the engines
pull the control stick about 1/3 travel. After the engines are cooled down,
order the Flight Engineer to shut down the engines.
3.9, Engine shutdown
3.9.1. Flight Engineer
(1) Switch off all the electric loads except for those required for operation of
the engines and its monitoring upon the Captain's order before he sets
idle power.
(2) Switch off the rectifiers, set the nO-500A INV selector switch to MAN
(PY4HOE), switch off the AC generators and report to the Captain.
(3) After cooling down the engines at idle shut them down by setting the fuel
