♦ 2.1.1 HOURMETER
This indicates the time the engine-generator has
operated, in hours and tenths of hours. Use
the hourmeter to ensure that the periodic mainte­
nance tasks for your generator are completed on a
timely basis.
♦ 2.1.2 START/STOP SWITCH
To crank and start the engine, hold this switch in the
START position. Release the switch when the engine
starts. To stop an operating engine, press emd hold
the switch in the STOP position until the engine shuts
off. The switch center position is the RUN position.
♦ 2.1.3 FUSE
The 14 amp fuse protects the engine’s DC control cir­
cuit against electrical overload. If the fuse element
has melted open due to overloading, the engine can­
not be cranked. If you must replace the fuse, use only
an identical replacement (SFE-14).
A
-------- ik CAUTION ik-------------------
If a fuse element melts, you should find the
cause of the overload before replacing the fuse.
The line (main) breaker protects the generator’s AC
output circuit against overload and provides a
method of turning OFF the generator’s 120/240-volt
AC output to the vehicle circuits. The QUIETPACT™
75D has two 35-amp breakers.
NOTE:
Refer to Section 1.4, “Generator AC Connection
System,” (Page 5). Individual installations will
differ. If an overload occurs, the dual breakers
will open the ungrounded(hot) stator leads (11
and 44). When the generator has been connected
for 120 volts only, the line breakers will operate
independently
on the ungrounded (hot) stator
leads (11 and 33).
♦ 2.1.5 PREHEAT SWITCH_______________________
The diesel engine is equipped with glow plugs, one
for
each cylinder. When you press the preheat
switch, the glow plugs heat the engine combustion
chamber
for quicker starts when the engine is
cold. Pressing the preheat switch also operates the
fuel pump.
2.2 OPTIONAL REMOTE START/STOP
This generator is equipped with a plug-in connector
which can be interfaced with an optional remote
panel provided inside the vehicle. This option allows
you to start and stop the generator conveniently from
within the vehicle. Refer to Part II - Installation
Instructions, Section 2.8 for details on the remote
start/stop option.
23 BEFORE STARTING THE ENGINE
NOTE:
Instructions and information in this manual
assume the generator has been properly
installed, connected, serviced, tested and
adjusted by a qualified installation technician or
installation contractor.
♦ 2.3.1 INSTALLATION___________________________
Generator installation must have been properly
completed so it complies with all applicable codes,
standards
and regulations and with the manufac­
turer's recommendations.
