Vehicle Structure The Volvo B9TL is a chassis prepared for bodybuilding of double-decked city buses. The chassis is low floor type. It is available in a choice of four wheelba- ses: 5150, 5300, 5910 and 7220 mm. Driver’s seat and Station Volvo dashboard available or instruments only supplied. Dashboard fully compatible with BEA2, two satellites on the right and the left side. Adjustable steering wheel, both height and tilt. Self canceling turn indicators. Dashboard, center: speedometer, rev coun- ter, AIC display, fuel gauge, coolant temperature, brakes, turbo and oil pressure, indicators, indicator lamps. Dashboard, left: emergency switch, tachograph, audio control panel (option). Dashboard, right: radio, climate control unit. Steering wheel, left satellite: control buttons, Light Control Panel. Steering wheel, right satellite: gearbox selector, doorbrake knob, switches and warning lamps. Instruments, behind engine: selector switch for front or rear operation, starting, charging lamp, mechanical stop, oil gauge. These con- trols enable the engine to be run and controlled from the tail of the vehicle during service work. Optional .............................................Tachograph Optional .......................................... Data logging Optional ................ External temperature meter Optional .......................Radio/phone switches ........................................... in steering wheel Electrical system The electrical system is a 24-volt system, where the chassis and engine frame are used as a ground. The battery’s negative terminal is connected to the chassis via the battery disconnector. There are three alternator ca- pacities available. 2nd generation Bus Electrical Architecture (BEA2) with electronic databus system Mul- tiplex 2 for data transmission, bus systems control, monitoring and coordination of all devices installed on the bus. Multiplex 2 also provides diagnostic information for driver and workshop. BEA2 features electronic control of the Engine Management System, transmission and suspension. For testing, callibrating and programming of the control units can be used a PC based software package VCADS- Pro. External lighting functions integrated in chassis Multiplex. They are activated by new Light Control Panel and controlled by Light Control Module. The system is equipped with three main switches: engine shut off, fuel shut off and electrical shut off. Tachograph system is available, analog or digital.
