Never operate the Allegro Bus if there is an electrical short present, as an electrical short may deliver an
electrical shock to anyone coming in contact with the exterior of the unit. If you should feel even the slightest
of electrical shock, immediately disconnect the unit from the 120 VAC power source and locate the electrical
fault (i.e., typically, it is a break in the grounding circuit).
Do not reconnect the 120 VAC power until after that electrical fault is fixed—the grounding circuit must be
continuous from the frame to the distribution panel, to the power cord, and to the earth ground so that
electrical-shock protection is realized.
12-Volt DC (12 VDC) Receptacles
Your Allegro Bus Motor Home is equipped with a 12 VDC receptacle conveniently located on the dashboard
or bulkhead. This 12 VDC receptacle can be used for providing power to various items, such
as cellular phones or personal computers or portable communications equipment.
This receptacle is usually found on the bulkhead or on the dashboard (i.e., the connector in
Figure 7-12) in front of the passenger’s seat so that it is conveniently available to be used by
the personnel in the cockpit area.
Multiplex System
Your motor home features a 12 VDC multiplex system (Figure 7-13). This system allows the ability to control
circuits from multiple locations in the coach. Each switch allows you to
turn a circuit on or off with individual button presses and provides an
indicator light to tell you the status of the circuit (i.e. whether it is on or
off). Many of the circuits are also dimmable by simply holding the button
to dim up or down.
Additional features of the multiplex system include the following:
•
Master Feature (
this is only on the control panel located at the
entrance door
)—this allows you to turn all lighting circuits on or
off with the press of a single button that is labeled “Light Master.” Pressing the Light Master “off”
switch will turn off all the interior lights within the coach. Momentarily pressing the Light Master “on”
switch will turn on the same circuits that were on when Light Master “off” was pressed. Light Master
“off” remembers which lights were on when the switch was pressed and will turn those same lights
back on when the Light Master “on” is momentarily pressed. Holding the Light Master “on” switch
will turn on all interior light circuits.
•
Switch Panel Back Lighting—all of the switches are backlit to make the labels easy to read. If you desire
to turn the panel lights off, a switch is conveniently located at the center of the coach labeled “Panel
Lights” which allows you to turn the back lighting On, Off, or Dim.
•
Status LED Indicator—a green LED beside each switch indicates whether the load is on or off. In
some cases, certain switches such as Awnings, Compartment Locks, and Generator do not have a
status indicator at the switch.
