Single Phase Loads on Three Phase Generators: Any
combination
of
single phase and three phase loading
can
be
used at the sametime
as
long
as
the cu rrent
for
any
output
lead does
not
exceed the generator
nameplate rating.
Output
Lead Markings: Leads on revolving field
generators are marked
T1,
P,
etc. Older models with
revolving armature generators had
output
leads
marked
M1, M2,
etc. These identifying marks also
appear on the wiring diagram.
SWITCHBOARD
Awall
mounted switchboard containing ammeters, a
voltmeter, and
circuit
breakers is optional. When
used, the following connections apply:
1.
Connect one ungrounded (hot) generator lead to
the unused terminal on each ammeter.
2.
Connect the generator lead and load wires which
are to
be
grounded to the ground stud on the
switchboard.
3. Connect one ungrounded (hot) load wire to the
unused terminal on each
circuit
breaker.
4. On sets that generate more than one voltage
(example:
120/240), the voltmeter should be
wired to indicate the higher
of
the
two
voltages.
RECONNECTIBlE
GENERATORS
The factory ships all special
order
sets with
in-
struments on the control panels completely wired
for
the voltage code
or
voltage specified on the
customers purchase order. Standard sets
without
instruments are shipped with the
T'-P
or
T'-T'2
output
leads separated in the
output
box. These
single phase and broad range generators are connec-
tible
or
later reconnectible 'to provide any
of
the
output
voltages shown in Figure
9.
Code 3C
or
'S3C Reconnectlble Generators: The
single phase,
60 and 50 Hertz generators have
output
leads
T1,
P, P,
and P available
for
making the single
phase voltage and load connections shown in Figure
9 at the installation site. Grounding procedu
re
should
comply
with local codes.
Code 18R
or
518R Reconnectible Generators: The
three phase, broad range,
60
and 50 Hertz
12
lead
generators have
output
leads
T'
through
T'2
available
for
making several single and three phase voltage
load connections shown in Figure
9.
Grounding
procedure should
comply
with local codes.
When connecting the output leads, be sure to connect lumperW10
on the voltage regulator printed
circuit
board between terminal
Y'
(common) and
Y', Y',

A broad range generator Is capable
of
generating numerous

Indicated by the reconnection diagram.
Code 9X Generators: These special

factory to provide
347/600 VAC.

BATTERY CHARGE RATE 'ADJUSTMENT
One generator wi'nding supplies current
for
the
battery charging circuit. The current flows to diode
CR",
ammeter

to the battery, and to the
ignition-
fuel solenoid control circuits, Figure 10.
