Functional Description (continues)
The information on the assets and the movement of the car alarms are the only ones that use the CAN-BUS
The drive system is fitted with an anti-overturning system based on the lateral acceleration signal from
an accelerometer on the Main Machine Controller (EB1) In the event this lateral acceleration value is
excessively high, the analogue maximum speed signal supplied by the Main Machine Controller to the drive
system board is reduced in proportion to the measured acceleration (the voltage value of the speed signal
depends also to the speed setting buttons
and varies tipically from 1 to 5 V)
Only on LPG/DIESEL version
The relay (ES8) is activated by the output of the auxiliary bridge rectifier D1, only when the engine is
running
The drive system, therefore, like the sweeping system, can only be activated with the engine running
