The AFC digital electronic fan control is a BODAS system solution for the easily adjustable control of hydrostatic fan drives. The BODAS RC controller controls one or two fan drives as a function of up to four temperature values and up to four digital inputs. The temperature values are recorded via sensors or via the CAN bus with the SAE J1939 protocol. Compared to standard solutions, the AFC considerably reduces energy requirements, noise emissions, fuel consumption and exhaust values. The control behavior can be influenced via the switch signals.

The integrated reversing function is used to reverse the direction of rotation of the fan motor for a short, adjustable period of time. This can be used in the case of very dusty ambient air to blow the cooler clear and restore optimal cooling performance. The cold-running phase of the combustion engine is reduced considerably by the standstill function. This further reduces fuel consumption and emissions.

The AFC fan control is perfectly matched to the Rexroth A10VO variable pump with ED electrohydraulic pressure control and one fixed motor. It is equipped with a fail-safe function which brings the fan motor to full speed in the event of faults, thereby safely preventing overheating of the combustion engine.

Diagnostics and parameterization of the system can be easily performed on site with the BODAS-service PC software.
