Automatic Fan Control AFC
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.
