Rosenbauer Chassis
Electrical Control System
V-MUX
What is it?
• The Weldon V-MUX is a central control system utilized by the
new Rosenbauer engines to manage and control the electrical
system on the apparatus and provide a centralized place for
the operator to activate and deactivate most of the electrical
components on the apparatus.
• The screen is located adjacent to the driver’s seat and will
sometimes also be referred to as the Vista Display.
• Most of the normal chassis operations can be found on one of
several screens displayed on the V-MUX.

High Idle
Operational Note:
• Chassis is equipped with an auto high idle feature
that will become enabled when system voltage
drops below 12.5 volts. It will automatically
disable when system voltage obtains 13.0 volts.

depressing and holding the service brake pedal or
by release of the park brake.
High idle system (auto or manual) will only operate
when the apparatus is in neutral and the parking
brake is set.

Traffic advisor control
Operational Note
• When the traffic advisor control head is in the off
position, the light bar on the rear of the apparatus
will come on in the warning or random pattern
when the E-master is activated on the V-MUX.
• In order for the operator to select a light pattern,
the operator must manually activate the controller
by selecting either high or low light intensity and
then select a flash pattern. Once the rocker is
switched to either high or low the light bar will
remain on independent of the E-master until the
controller is switched off.
