used either to reinstate an off-line generator or
to take a malfunctioning generator off line.
Momentary positioning of the GEN switch to
TRIP opens the GLC and generator field cir-
cuit. With a generator off line due to TRIP se-
lection or because of operation of any of the
GCU protection devices, holding the GEN
switch to CLOSE for five seconds may rein-
state the generator. The generator comes back
on line, provided no fault exists, when the
switch is released.
Ammeters
A dual ammeter is provided (see Figure 2-
17). The left ammeter indicates No. 1 gener-
ator load or No. 1 battery charge rate; the
other indicates No. 2 generator load or No. 2
battery charge rate. A BATT pushbutton and
a 0-40 pushbutton are also fitted.
With generators on line, each ammeter nor-
mally indicates the load on the associated gen-
erator in the range of from 0-450 amperes.
Readings should be approximately equal if
the equalizing circuit is functioning correctly.
The maximum permissible discrepancy be-
tween readings is 40amperes.
When the BATT button is pressed, the charge
rates of No. 1 and No. 2 batteries are indicated.
If the battery charge rate cannot be read eas-
ily on the full instrument scale, the 0-40 switch
should also be pressed. With both buttons
pressed, the value of the graduations on both
ammeters is divided by 10, and the ammeter
scales represent a range from 0-40 amperes.
This facility may only be used when the charg-
ing rate is less than 40 amperes. (Immediately
after an internal start, the charging rate may
be as high as 150 amperes.)
A red segment is marked on each instrument
dial to cover the range above 400 amperes; the
300-400 ampere range is marked in orange.
Voltmeter
A voltmeter (Figure 2-13) indicates the volt-
age of the installed batteries or the voltage on
bus bars PS2, PE, or PS1 when an adjacent six-
position selector switch is set appropriately.
The positions are labeled “B1-B2-PS1-PE-
PS2-AUX 3-4.”
APU
Either of two types of APUs may be installed
(Figure 2-18). Both perform the same functions,
which are to provide a supply of DC electrical
power and bleed air for air conditioning on the
ground. The two manufacturers are Garrett/AiRe-
search and Solar. While control configuration
