THEORY OF OPERATION - CONTINUED
The operators cab is a sound and weather insulated unit that provides the operator with the systems to control and mon-
itor both standard automotive functions and container handling functions. The following components or systems are also con-
tained within the cab:
Adjustable steering column and adjustable suspension seat.
Heater, air conditioning, and filtered ventilation system.
Portable fire extinguisher and rifle mount.
AIR CONDITIONING SYSTEM
The air conditioning system unit is part of the heater and is mounted at the front of cab. It is a single unit consisting of a
heater core, air conditioning evaporator coil, blower motor, control valves, and air ducts.
The system is turned on by the air conditioning control switch on the instrument panel in the cab. The two-speed blower
switch controls flow rate.
An even cab temperature is maintained by controlling the refrigerant flow through the evaporator coil, by the air condi-
tioner temperature control switch.
The RT 240 is equipped with several electronic modules, all connected using CAN-BUS technology. The modules can
be diagnosed using the IETM and OEM testing equipment. They assist in the operation of major systems such as engine, trans-
mission shifting, steering mode and wheel position, the safe working load control, and many related functions that require data
input to operate correctly for the intended uses of the RT 240.
