10.1 General The electrical system of the truck is based on the PowerDrive platform. • The main power source is a 24 V DC traction battery. • The travel drive motor is a separate excitation type (SEM) . The travel drive motor is operated by an enclosed transistor regulator relying on pulse width modulation (PWM) technology. The transistor regulator also controls the input and output signals for truck travel and lifting operations. • The lift unit motor is a conventional DC motor without any external field winding connections. Switch-on of the hydraulic unit's electric motor is achieved using a contactor. • The truck also features electric power steering. The power steering servo and the motor have been integrated as one unit directly onto the driving gear mounting plate. • All electric units communicate via a CAN bus with an IC card in the steering unit handle. This card contains a processor and software that controls and monitors truck functions. A set of parameters used to adjust truck functions and characteristics is stored in the card. The card also monitors error conditions that may occur.
