Contents of this documentation
The AFC30 is a fan control especially designed to cool engines of mobile machines.
The AFC30 controls a single hydrostatic fan drive (either a variable pump with a fixed
motor or a fixed pump with a pressure-relief valve mounted on a fixed motor).
This document describes how to install, configure, and commission the AFC30 fan
control. The configuration and the commissioning of the fan control are performed
by setting values for various parameters in the fan control software. This so-called
parameterization is performed using the BODAS-service software.
Before you parameterize the AFC30 fan control, it is important to understand which
parameters can be set, how they relate to each other, how the values are processed,
etc. This document therefore contains an overview of the basic concepts of the fan
control and the general workflow for using the control. It also describes the features
of BODAS-service which are required to perform the commissioning.
For general information about BODAS-service, please refer to the Online Help, which

4 Product description
The AFC30 is a fan control especially designed to cool combustion engines.
The AFC30 fan control contains various features to improve the energy and fuel
consumption, noise emission, and exhaust values compared to conventional fan drive
controls.
The AFC30 controls a single hydrostatic fan drive (either a variable pump with a fixed
motor or a fixed pump with a pressure-relief valve mounted on a fixed motor).
4.1
Hydraulic configurations
The AFC30 fan control can be used as part of one of the following setups:
•• A variable displacement pump with a fixed displacement motor
•• A fixed displacement pump and a fixed displacement motor with a pressure-relief
valve
For a more detailed list of components, refer to the datasheet (95362).
The fan speed is defined by setting the system pressure, either at the pump
controller or on the pressure-relief valve. The required pressure is calculated by the
software according to the measured temperatures, retarder values, etc. The two
hydraulic concepts are illustrated in the following schematics:

16/108
Product description
Fan control
The software then controls the fan drive at the highest requested power. Using time
ramps you can configure how quickly the fan responds to a change in the requested
power.
Further inputs and
outputs
The fan power can also be influenced by a retarder signal. The retarder is typically
used to slow down a vehicle by generating hydraulic friction on the drive train.
The AFC30 fan control has a single digital output. The temperature input signal used
to control this digital output can be selected. An error lamp and operational lamp are
available as well.
Other features
The AFC30 also contains the following features:
•• Fan speed:The actual speed of the fan can be read by using a DSM sensor, HDD1,
DSA1 series 12 sensor, or inductive sensor
•• Fan speed limitation: This avoids torque peaks on the diesel side
•• Shut down management: Allows the fan to be stopped smoothly
•• CAN diagnostic
For more information on each of these features and how they relate to each other,
see chapter 5 “Basic concepts” on page 21.

5 Basic concepts
Before you start to parameterize the AFC30 fan control, it is important to understand
which parameters can be set, how the various parameters relate to each other, how
their values are processed, etc.
This chapter provides an overview of the basic concepts which you should
understand before planning or setting parameters.
For information about the range of values permitted for each parameter, the default
value, etc. see chapter 7 “Parameters” on page 59.
5.1
Temperature curves
The AFC30 fan control can monitor the following temperatures:
•• Engine intake manifold temperature (1.1.x by default)
•• Engine charge air coolant outlet temperature (1.2.x by default)
•• Hydraulic retarder oil temperature (1.3.x by default)
•• Engine coolant temperature (1.4.x by default)
•• Engine oil temperature (1.5.x by default)
•• Transmission oil temperature (1.6.x by default)
•• Ambient air temperature (1.7.1-2)
•• Input from fluid TSF temperature sensor (2.1.1-4)
•• Input from air TSA temperature sensor (2.1.1-4)
•• Input from Bosch NTC-fluid sensor with negative characteristic sensor (2.1.1-4)
•• Input from Bosch NTC-air sensor with negative characteristic sensor (2.1.1-4)
•• Freely configurable fluid temperature sensor (2.1.1-4)
•• Freely configurable air temperature sensor (2.1.1-4)
•• Analog voltage temperature sensor (2.1.5-6)
•• Freely configurable J1939 CAN-bus message (1.1.1 – 1.6.1)
Up to six temperatures can be monitored in total (up to six from the CAN bus, up to
four from resistive sensors, and up to two from analog sensors).
You can specify which of the temperatures are monitored and thus which
temperatures influence the fan power.
Three points have to be parameterized for each selected temperature (except for
ambient temperature). These points are used to calculate the requested fan power
for that temperature.
The fan is operated at the highest power requested by any of the selected
temperatures and the retarder. For more information about the retarder, see section
5.3 “Retarder” on page 26.
For more information about the fan control, see section 5.4 “Fan power” on page
29. The ambient air temperature (3.7.1) does not influence the fan power directly.
Instead it influences the fan power requested by the input temperatures. For more
information, see section 5.2 “Ambient air temperature” on page 24.

Thresholds
The temperature curve is defined by the following thresholds:
•• Minimum temperature, Tmin:
Temperature at which the fan starts to operate.
Under Tmin, the fan power remains at 0 %.
•• Maximum temperature, Tmax:
Temperature at which the fan operates at maximum power.
Above Tmax, the fan power remains at 100 %.
•• Over-temperature, Tover:
•• If the temperature reaches this value, an error occurs:
––The error lamp flashes
––An error message is displayed in BODAS-service
For more information, see section 9.3 “Error codes and messages” on page 91.
The fan power increases linearly between Tmin and Tmax.
During the commissioning or the configuration of the AFC30 fan control, you specify
the Tmin, Tmax, and Tover temperature thresholds of each selected temperature input.
Ramp times
A ramp time is available for each temperature to define the maximum temperature
gradient.The rising and falling ramps are independent of each other.
For more information, see section 5.15 “Time ramps” on page 45.
Debouncing times
To avoid the influence of rapid temperature increases on the fan drive system (e.g.
due to EGR), the fan power request can be debounced by a calibratable time tdly.
The fan power request has to be > 0% for time tdly to activate the fan (or disable the
Stop Function).

Ambient air temperature
The ambient air temperature (3.7.1) does not influence the fan power directly.
Instead it influences the fan power request by the source temperature.
The thresholds of the curve associated with the charge air temperature (see section
5.1 “Temperature curves” on page 21) are increased when the ambient air
temperature exceeds a pre-defined temperature.
You can configure the following parameters for the ambient air temperature:
•• Start temperature, Tstart (3.7.2)
Temperature at which ambient air temperature starts influencing charge air curve
•• Stop temperature, Tstop (3.7.3)
Temperature at which ambient air temperature stops influencing charge air curve
•• Increase ramp (3.7.4)
Gradient at which the temperature increases
•• Decrease ramp (3.7.5)
Gradient at which the temperature decreases
For each increase of 1 °C in the ambient air temperature between the start and stop
temperature, the thresholds of the charge air curve also increase by 1 °C. This is the
same as shifting the charge air curve right by 1 °C.

Basic concepts

When the ambient air temperature exceeds Tstop (3.7.3), the shifting stays
constant. For example, if Tstop = 40 °C, the curve shift is the same at an ambient air
temperature of 40 °C or 45 °C.
You can also specify how quickly the temperature increases (3.7.4) and how quickly
the temperature decreases (3.7.5). For more information about ramp times, see
section 5.15 “Time ramps” on page 45.
Example
Notice! The ambient dependency in the ASrun version works only if the input
AmbTDpdEna_s Pin 35 (IN_4) – is enabled meaning:
▶▶ Wired and active with the high potential when configured as - Normal (High
active) 2.2.4 Amb T Dpd Ena - Type
▶▶ Wired or not wired and active with the low potential when configured as Inverted
(Low active) 2.2.4 Amb T Dpd Ena - Type
Requirement: The fan should operate when the charge air temperature exceeds
30 °C (e.g. parameter 3.1.2 = Tmin = 30 °C).
Problem: During the summer, the ambient temperature can reach 35 °C. Due to the
high ambient temperature, the charge air temperature will never stay under 30 °C.
Therefore, the fan will always be on without achieving the desired cooling effect, i.e.
some energy is wasted.
Solution: The fan power requested by the charge air temperature has to be
dependent on the ambient air temperature.
Configuration of the solution:
•• Ambient air temperature dependency (3.7.1) = ON
•• Tstart (3.7.2) = 25 °C
Results:
•• For ambient air temperatures < 25 °C, the fan starts when the source (e.g. charge
air) temperature = 30 °C.
•• For ambient air temperatures ≥ 25 °C, the source temperature at which the fan
starts raises by 1 °C for each degree increase in the ambient air temperature (same
consequences for source temperature at which the fan operates at maximum
power).
Therefore, at an ambient air temperature of 35 °C, the fan will only start when the
source temperature is 40 °C.

Retarder
The retarder creates a hydraulic resistance against the motion of the motor. This is
useful as it helps the vehicle to slow down. However, when the retarder is used, the
oil that creates the hydraulic resistance becomes warm and therefore the fan has to
be operated.
Parameter 4.3.1 enables the function which reads the retarder value and computes
the fan power required to cool the retarder.
The retarder is turned on and off by the driver of the vehicle using a lever. The fan
starts to cool the oil as soon as the retarder is turned on (i.e. it does not wait for the
oil to become warm, it starts to cool immediately).
Nevertheless, the retarder signal is ignored if any of the following conditions are
true:
•• If the first temperature source is enabled (4.3.3) and is below a threshold (4.3.4).
•• If the second temperature source is enabled (4.3.5) and is below a threshold
(4.3.6).
•• The retarder signal is read from the CAN bus (4.3.1) and an ERC1 error (timeout or
invalid message) is present.
The retarder value can be read from the following sources:
•• Digital input (4.3.1 = Rtdr Dig Inp)
•• CAN bus signal (4.3.1 = CAN ERC1)

The values from the CAN bus are always negative; the larger the negative value is, the
higher the fan power.

If one temperature signal requests a power of 50 % and the other a power of 80 %,

Time ramps
You can apply a rising (5.1.4) and/or falling (5.1.5) time ramp to the fan signal to
ensure smooth operation. The time ramps do not have to be identical. For more
information about time ramps, see section 5.15 “Time ramps” on page 45.
Curve logic
For safety reasons, the valve that controls the fan is typically configured so that it
delivers maximum oil flow to the hydraulic motor when it receives zero current. This
ensures that the fan operates at maximum power if a cable breaks. For such valves,
negative logic (5.1.3) is used.
RE 95362-01-B/09.2018, AFC30, Bosch Rexroth AG
30/108
Basic concepts
Example of negative logic:
•• Requested fan power = 100 %
The current = Imin so that it delivers maximum oil flow. This results in maximum fan
speed.
•• Requested fan power = 0 %
The current = Imax so that it delivers minimum oil flow. This results in minimum fan
speed.

You can specify the minimum (5.1.1) and maximum (5.1.2) current sent to the
solenoid.
You can also specify whether the current sent to the solenoid goes to zero or stays
at the minimum value when the fan power request is 0 % (for positive configuration)
or 100 % (for negative configuration) (5.1.7). When this parameter is set to on, the
current will hold at the minimum value, and when set to off the current will go to
0 mA.

External digital fan power request
The fan power can also be influenced by a digital input (2.5.1). This digital input has
an associated set point (2.5.2) which is included in the calculation of the fan power
when the digital input is active. The fan speed limitation described in the previous
section always has priority over the external digital fan power request regardless of
the mode.
Modes
The digital external fan power request can be set to one of the following modes:
•• Off
In this mode, activating the digital input has no effect on the calculation of the fan
power request.
•• Minimum value
In this mode, the fan power request does not fall below the set point value when
the digital input is active.
The following figure shows an example when the set point value is 30 % and the fan
power request from the temperature inputs is 0 %:

Standstill
The fan can be set to standstill if a stop valve is installed and no fan power is
requested from any source. Up to 2 temperature paths (4.6.1, 4.6.4) can be used to
determine if the fan should be stopped. If both are set to off, the standstill function
is disabled.
The output for the stop valve can be configured as either a high active output or a
low active output (5.2.2).

Basic concepts
Thresholds
If the first temperature source drops below T1low (4.6.2) and stays below this
temperature for a settable time (4.5.1) and the second temperature source drops
below T2low (4.6.5) and stays below this temperature for a settable time (4.5.7), the
fan is switched to standstill mode:
1. The requested fan power is 0%
2. The delay time (4.6.8) is passed or the fan speed is below a defined and
measured fan speed (4.6.7)
3. Then the stop valve is energised.
The fan is stopped until the first temperature source goes above T1high (4.6.3) for
a settable time (4.5.6) or the second temperature source goes above T2high (4.6.6)
for a settable time (4.5.8). If one of these temperatures is reached for the specified
time the fan operates normally (i.e. the stop valve is deactivated and RC controls the
fan behavior).

Digital output
One of the temperature signals (4.5.1) can be used to control a digital output. You
can specify an upper (4.5.3) and lower (4.5.2) temperature threshold.
The following states are possible:
•• If the value of the selected temperature is above the upper temperature then the
output is active.
•• If the value of the selected temperature is below the lower temperature then the
output is inactive.
This leads to a hysteresis curve: the output only changes after passing through the
range between the two thresholds.

5.10 Fan speed
The fan rotation frequency can be read using the following sensors (2.3.1):
•• DSM sensor
•• HDD1 / DSA1 series 12 sensor
•• Inductive sensor
All the sensors work by counting the number of teeth on a rotating shaft. Therefore
you must specify the number of teeth (2.3.2) to calculate the fan rotation speed from
the frequency.
RE 95362-01-B/09.2018, AFC30, Bosch Rexroth AG
38/108
Basic concepts
The fan rotation direction can also be read for certain sensors. For a DSM sensor the
direction is evaluated in the software based on the pulse lengths. For a HDD1 / DSA
series 12 sensor, the direction is read using a calibratable digital input (2.3.3). For
an inductive sensor the direction is not determined.
You can also configure that the actual fan speed is sent to the CAN bus to enable it
to be read by other ECUs (5.3.4).

5.11 Low Current Control
The fan control can operate under open-loop control when the current drops below a
settable current (5.8.5) for more accurate control at low desired currents. Once the
desired current is above the threshold current plus the settable hysteresis (5.8.6),
closed-loop control will once again resume control of the fan.
Thresholds
In order for the open-loop control to work properly, two measurement points must
be used to determine the slope of the current. When the desired current reaches
the high current point (5.8.1), the desired current will freeze at this value for a
specified time period (5.8.3). Fan operation will continue normally until the desired
fan current reaches the low current point (5.8.2). At this point the desired current
will once again freeze for the same specified time period (5.8.3). A scaling factor
can be set which offsets the slope at very low currents for better accuracy.
For the low current control to work properly, the high current point (5.8.1)
must be greater than the low current point (5.8.2). To achieve the most reliable
measurements, the pause time (5.8.3) should not be set less than 0.25 second. For
optimal results the threshold current (5.8.5) should be set to 120 mA.

5.12 Reversing
The fan direction can be reversed for both fixed and variable pump systems that have
a reversing valve. This is useful in dusty conditions for cleaning dirt from the radiator
to allow for more efficient cooling. The oil flow to the fan motor is first stopped and
then the flow direction is reversed by either a 4/3-directional valve (variant 1) or a
4/2-directional valve in combination with a fan standstill valve (variant 2).
Procedure
The following is the procedure for reversing the direction of rotation in a variable
pump system. In fixed pump systems, this function operates in an analogous manner
with the aid of a bypass valve (pressure-relief valve) instead of the pump control
valve. For a fixed pump system only variant 2 can be used.
1. Normal state: Fan delivers power as requested
2. Standby state - step 1: The variable pump is throttled via the time or speed ramp
to the minimum pressure
3. Standby state – step 2: The speed of the fan decreases until it is less than the
maximum speed in standby (4.8.1) and/or the time in standby (4.7.5) is reached.
4. Standstill state – step 1: The fan standstill is activated as follows:
––Variant 1: Reversing valve switches to the H-position
––Variant 2: Standstill valve is activated
5. Standstill state – step 2: The speed of the fan drops until it is less than the
maximum speed in standstill (4.8.2) and/or the time in standstill (4.7.6) is
reached.
6. Standby reverse state: The fan standstill is deactivated as follows and rotation in
the reverse direction is initiated:
––Variant 1: Reversing valve switches to the cross position
––Variant 2: Reversing valve switches to the cross position, the standstill valve is
subsequently deactivated.
7. Standby reverse state: The minimum system pressure will accelerate the fan
until it reaches the minimum speed in standby (4.8.3) and/or the time in standby
(4.7.5) is reached.
8. Normal reverse state: The pump flow control is ramped up to the desired fan
power level in reversing (4.8.8). The fan system will stay in this state for the
specified amount of time (4.8.4).
9. The above procedure is reversed to bring the fan back into normal operating
mode.
Activation modes
The reversing function can be turned off or can be activated using 4 different modes
(4.7.1):
•• Off:
In this mode, reversing will not be activated.
•• Periodic with activation with the digital input:
In this mode, reversing is activated periodically based on the interval time (4.7.3).
Reversing is also activated for one cycle when the digital input is active.

Basic concepts
Control Modes
Once the reversing function is activated, the different states (standby, standstill,
reverse standby, reversing) are transitioned using one of the following four modes
(4.7.4):
1. Speed sensor:
In this mode, the states are transitioned using fan speed only. This is only
possible when a frequency sensor is used for the rotational speed of the fan. The
parameters should be set up as follows:
––“Max speed in standby“ (4.8.1) as a threshold to leave standby/reverse standby
state towards standstill state
––“Max speed in standstill“ (4.8.2) as a threshold to leave standstill state towards
reverse standby/standby
––“Min speed in standby“ (4.8.3) as a threshold to leave standby state towards
normal operation/ reversing
The following figure shows an example of transitioning between the different states
using the fan speed as the basis:
Fig. 23: Example of reversing using speed-based transitions
A debounce time (4.8.6) can also be used for the fan speed. This sets the
consecutive time interval the fan speed must fulfill the speed condition before
transitioning to the next state. If the speed condition is not fulfilled, the interval
timer resets. This is useful for noisy signals from the speed sensor.
Bosch Rexroth AG, AFC30, RE 95362-01-B/09.2018
Basic concepts
43/108
2. Time delay:
In this mode, the states are transitioned using time delays only. This should be
used if a frequency sensor is not available for the fan speed. A timer is used to
determine how long to spend in standby (4.7.5), how long to spend in standstill
(4.7.6), and when to resume normal operation (4.7.7), which is the time from
standstill to normal operation.
3. Speed sensor or time delay:
In this mode, the states are transitioned using the fan speed feedback from a
frequency sensor or time delays, depending on which event happens first. This
is useful in case an error occurs with the fan speed sensor so the reversing
operation will still complete based on the time delays.
4. Speed sensor and time delay:
In this mode, the states are transitioned using the fan speed feedback from
a frequency sensor and time delays. This is useful for fans with large inertias
where, if the time delay is not long enough and the fan transitions states while
the fan is still rotating at a high speed, could cause damage to the system and
injury to the operator.

If the analog sensor suffers an error, the value 0xFE will be written to the bus.
Fan speed
It is possible to write the desired and actual fan speed to the CAN bus (5.3.4).
If the actual fan speed is written to the CAN bus and no sensor signal is available
(2.3.1) the value 0xFFFF is transmitted.
If the actual fan speed is written to the CAN bus and the sensor has an error, the
value 0xFEFF is transmitted.

Diagnostic messages
If an error is detected, the customer can identify it without the Rexroth Diagnosis
Tool by any J1939 conform Diagnosis-Tool (5.3.3). If enabled (5.3.3), messages DM1
and DM2 are sent.
•• DM1 is transmitted every 1 second
•• DM2 is sent only for request
•• DM2 consists of all errors that are saved in BODAS-service memory.
•• Errors are not sent by a DM2 message if the BODAS-service memory has been
deleted.
For details, see section 9.2 “J1939 diagnostic message“ on page 90

It’s possible to send additional proprietary messages (5.3.5 – 5.3.7). These contain
information about the Automatic Fan Control including:

helps to ensure that the fan operates smoothly as it prevents the fan speed from
fluctuating excessively.

Fig. 32: Checking the parameters for errors
When you have finished setting the parameters, BODAS-service automatically checks
whether the parameter values are suitable, for example whether the maximum
temperature is higher than the minimum temperature, whether two sensors are
assigned to the same pin, etc.
You should check the errors and rectify them before continuing. A full list of error
codes and their meanings can be found in chapter 9 “Troubleshooting”.
1. Click the Error messages menu in the left panel.
A list of active errors and saved errors is displayed in the right panel.
2. For each active error, look up the error code in chapter 11 “Alphabetical index” on
page 105 and follow the advice to rectify the fault.
The error is automatically removed from the list once it has been rectified.
3. Once all errors have been rectified, continue with the parameterization or save
your parameterization.
For more information about errors that occur during operation, see chapter
9 “Troubleshooting” on page 89.

6.10 Commissioning example
Requirements
A coach company in Spain has purchased a new AFC30 fan control for their buses.
They have the following requirements:
•• The charge air temperature, ambient air temperature, and hydraulic temperature
should be measured.
•• The charge air temperature should be read from the CAN bus. The fan should turn
on at 45 °C, have maximum power at 60 °C and above, and report an error at 70 °C
and above. It should have a ramp time of 25 s.
•• The ambient air temperature should be read from a resistive sensor via pin 18. It
should influence the charge air thresholds between ambient air temperatures of
25 °C and 60 °C.
•• The hydraulic temperature should be read from a resistive sensor via pin 6. The fan
should turn on at 60 °C, have maximum power at 70 °C and above, and report an
error at 90 °C and above. It should have a ramp time of 50 s.
•• A retarder is available and the values of the retarder should be read from the
CAN bus. Three different retarder values should be considered with a linear
interpolation for the values in between:
––Retarder value -110 % = 100 % fan power
––Retarder value -80 % = 85 % fan power
––Retarder value -50 % = 40 % fan power
•• The retarder should only be active at ambient air temperatures above 25 °C.
•• The solenoid that controls the fan is configured so that it delivers maximum power
to the fan when it receives zero current (safety feature for wire breaks). The
minimum current sent to the solenoid should be 0 mA and the maximum 600 mA.
•• The actual fan speed and the desired fan speed should be sent to the CAN bus so
they can be read by other ECUs.
•• The ambient air temperature should be monitored and used to control the digital
output. The output should be on above 30 °C and off below 20 °C.

Introduction
CAN Signals
CAN (Controller Area Network) bus allows communications among microcontrollers
and devices. A CAN bus is typically connected to sensors, actuators, and other
control devices. The data sent from one device to another are segmented into frames
(messages) before transmission. A message consists primarily of an identifier (ID),
and up to 8 bytes of data. The figure below shows the overall structure of a CAN
message:
Structure of a
CAN message
Fig. 35: Structure of a CAN Message
According to protocol J1939, every message contains a 29-bit CAN ID, which
includes information regarding the priority of the message, and an up-to 8 bytes of
Protocol Data Unit (PDU), which contains the actual data to be transmitted.
Furthermore, a CAN ID is divided into three segments:
•• 3 bits of Priority,
•• 18 bits of Parameter Group Number (PGN),
•• 8 bits of source address (SA).
The PGN is further divided into:
•• Extended Data Page,
•• Data Page,
•• PDU Format,
•• PDU Specific.
The figure below shows the detailed structure of a CAN ID:
Fig. 36: Structure of a CAN ID
Bosch Rexroth AG, AFC30, RE 95362-01-B/09.2018
Signal reference
Structure of a PDU
83/108
The PDU contains the actual data to be transmitted in the message. Each signal has
its pre-allocated space (either 1 byte or 2 bytes) in the PDU.
The following picture shows the PDU format:
Fig. 37: Structure of a PDU
CAN input signals
The following signals can be read from the CAN bus as J1939 CAN information:
1. Configurable CAN signals (temperatures and power)
2. Defined CAN signals (engine speed, ambient temperature and retarder torque).
Example
In this example, the temperature parameters need to be configured in the BODASservice software. Specifically, the user needs to define the following details
regarding a specific parameter in BODAS-service according to protocol J1939-71.
•• Number of bytes in the PDU
•• Start position in the PDU
•• PDU Format (in decimal)
•• PDU Specific (in decimal)
•• Source address

Signal reference
To calibrate Engine Oil Temperature (SPN 175) in message ET1:
1. Search for ‘SPN 175’ in the protocol J1939-71
2. User should be able to find the information shown in the protocol J1939-71, as
shown in Table 36.
––Copy the PGN specified at the end.
3. Search for the PGN number specified (i.e. PGN 65262) in the protocol J1939-71
4. User should be able to find the information shown in the protocol J1939-71, as
shown in Table 37.
5. Extract information needed for BODAS-Service:
––Number of bytes in the PDU: 2
––Start position in the PDU: 3 (‘3-4’ as given in the protocol)
––PDU Format (in decimal): 254
––PDU Specific (in decimal): 238
––Source address: application specific (i.e. not included in the protocol)

The following signals can be sent to the CAN bus as J1939 CAN messages. This
enables the values to be read directly from the CAN bus, e.g. by a PC or by another
ECU.
Calibrate the source address of the RC with ASrun-AFC30 (5.3.1). The messages
are only sent to the CAN bus if the parameter (5.3.5 – 5.3.7) to enable the
corresponding proprietary CAN message is set to ON.

Some CAN output signals are sent with an offset, e.g. the value 0 is sent for a
temperature of -40 °C.
It is important to take the offset into account if reading data directly from the
controller, or if another ECU reads data from the controller.

9 Troubleshooting
This chapter describes how to detect and rectify faults with the AFC30 fan control.
If the system detects a fault, the following occurs:
•• The fan works with maximum speed, if the hydraulic control shows a negative
characteristic (no current at output = max. oil flow).
This is to ensure that motor does not overheat even if the exact temperature
cannot be read
•• The error lamp flashes with an appropriate error code.
The sequence with which the error lamp flashes provides information about what
fault has occurred
For more information about the sequence of flashes, see section 9.1 “Error lamp”
on page 89.
•• The faults are logged in the control unit.
They can be read using BODAS-service
For more information about the error messages, see section 9.3 “Error codes and
messages” on page 91.
•• DM1 and DM2 messages can be used to identify faults.
For more information about the SPN/FMI, see section 9.2 “J1939 diagnostic
message” on page 90.
9.1
Error lamp
The error lamp is used to indicate that a fault has occurred. When a fault occurs,
the lamp flashes with short or long pulses of light followed by a delay. The sequence
of long and short pulses is referred to as an error code. If more than one error is
present, then the error codes are indicated in sequence in a continuous loop. Only
errors that are currently present are indicated.
When the fan control is turned on, the error lamp lights for two seconds to indicate
that it is functioning correctly.
Sequence of flashes
The following rules define how the error lamp flashes:
•• Each error code consists of a sequence of long and short pulses
•• A long pulse lasts 1000 ms
•• A short pulse lasts 500 ms
•• Long pulses always preceded short pulses
•• There is a delay of 500 ms between two pulses
•• There is a delay of 2 s between two error codes
Once you have identified an error code, look up its meaning in section 9.3 “Error
codes and messages” on page 91.

Example
The following diagram shows an example of the error lamp. Each square represents
500 ms. The red rectangles represent the error lamp being on:
Control

code 13
Time
[500 ms]
Fig. 39: Error lamp example
•• 2000 ms pulse when fan control turned on to indicate error lamp operating
correctly
•• Two long pulses, one short pulse
= Blink code 21
•• One long pulse, three short pulses
= Blink code 13
•• The cycle of error codes repeats continuously until they are solved
9.2
J1939 diagnostic message
If one or more errors are active, a DM1 message is sent every second. This function
can be activated by (5.3.3).
For details regarding the contained J1939 Fault Lamps information, see section 9.3
“Error codes and messages” on page 91.
You can use SPN and the FMI listed in section 9.3 “Error codes and messages” on
page 91 to identify the cause of the fault(s).
The following applies for diagnostic messages:
•• DM1 requests are ignored
•• A DM2 message request is required to send details of passive faults
•• DM11 messages are ignored
Note: The SPNs and FMIs in the AFC30 specific DM1 message are not compliant with
the J1939.

Short, low-resistance connection from a case screw to the vehicle ground.
Separate ground connection to battery (chassis possible).
3) Separate fuse protection for sensors supplied from UBat, and solenoids switched to ground. Fuse
configuration specific to application (in particular current needed and line cross section).
4) CAN bus: 120 Ω termination resistor and twisted line necessary.
5) Constant voltage sources can be used as sensor supply or
switching voltage for switches/push-buttons.
6) The power line to consumers wired to ground must be fused, see 3).
7) Can be adjusted to the actual current consumption of the consumers and must
be adjusted to the permissible load of the lines and pins.
8) Independent ground connection of the current source to the battery, controller ground possible.
9) Can be used as switching inputs.
10) Alternatively, can be used as input.
11) If deactivated during operation, data will not be saved in the
non-volatile memory and there will be no after run.
12) First deactivation channel: deactivation with level < 3.1 V;
activation with level > 7.9 V.
When deactivated, the main switch for the power supply to the high-side output stages is
opened by the hardware and the low-side output stages are deactivated.
13) Second deactivation channel: deactivation with level >1.3 V; activation with level > 7.9 V.
14) Terminal 31 (ground supply) and sensor ground are joined at a star point in the controller and
are connected to the housing.
15) Optional, normally connected to UBat / VB
16) Not protected against short circuit to ground and UBat.
e) Inputs/outputs and corresponding functions are calibrateable in ”Expert View“ of BODAS-service. Login with password is required.
