Component Description For Starter-Alternator - GF15.40-P-2103FG

Model 213 with engine 264 

up to model year 2021 

with code B01 (48V technology) 

Shown on engine 264 

Location 

The starter-alternator is located at the side on the engine.

Tasks 

The starter-alternator contains a power electronics part via which the operating mode is set. Internal actuation of the power electronics determines how much electrical energy the starter-alternator generates or consumes.

The starter-alternator has the following further tasks:

• Reading in of sensors and signals 
• Evaluation of input factors 
• Sending signals 

Reading in of sensors and signals 

The input factors are read in via the following connections:

• Direct line 
• Hybrid CAN (CAN L) 

Direct line 

The circuit 30c signal (crash signal) is read in via a direct line.

Hybrid CAN 

Among others, the starter-alternator reads in the following signals via the hybrid CAN:

• Permissible current and voltage limits
• Mode

Evaluation of input factors 

The integrated microprocessor evaluates the input factors read in.

Sending signals 

Among others, the starter-alternator transmits the following signals via the hybrid CAN:

• Alternator utilization

The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
