24 RC10-10 Series 31 | BODAS Controller
Safety instructions
Notes on transport and storage
▶ If it is dropped, the controller must not be used any
longer as invisible damage could have a negative impact
on reliability.
▶ Control units must be stored with a mean relative
humidity of 60% and at a temperature between -10 °C
and +30 °C. Storage temperatures between -20 °C and
+40 °C are briefly permissible, for up to 100 hours.
▶ After a storage time of more than 5 years, the controller
must be examined by the manufacturer.
Notes on wiring and circuitry
▶ The electronics and the power outputs of a controller
must be fed from the same power source.
▶ When wiring the output stages, the maximum cumulative
output current for each output stage group should be
noted. The cumulative output current means a
permanent, simultaneous actuation of the output stages.
▶ Lines to the speed sensors shall be as short as possible
and shielded. The shielding must be connected to the
electronics on one side or to the machine or vehicle
ground via a low-resistance connection.
▶ The product may only be wired when it is de-energized.
▶ Lines to the electronics must not be routed close to
other power-conducting lines in the machine or vehicle.
▶ The wiring harness should be fixated mechanically in the
area in which the controller is installed (spacing < 150
mm). The wiring harness should be fixated so that
in-phase excitation with the controller occurs (e.g. at
the controller bolting point).
▶ If possible, lines should be routed in the vehicle interior.
If the lines are routed outside the vehicle, make sure
that they are securely fixed.
▶ Lines must not be kinked or twisted, must not rub
against edges and must not be routed through sharp-
edged ducts without protection.
▶ Lines are to be routed with sufficient spacing to hot or
moving vehicle parts.
▶ PWM outputs must not be linked or bridged.
▶ PMW outputs with current measurement (OUT_1 to
OUT_4 and OUT_19 to OUT_24) must not be used to
power bulbs.
▶ The sensor supplies can be „pulled up“ by an external
connection, e.g. the application of a higher voltage,
because they operate only as a voltage source but not as
a voltage sink. Pulling up a sensor supply may result in
unexpected malfunctions and damage of the controller
in lasting operation.
▶ The „high side“ outputs may not be externally connected
to battery.
▶ If the stop function is used in an application, the
contacts 9 and 18 (HW_INH_1, HW_INH_2) of the
controller must be connected to the stop switch in the
vehicle. For a dual channel switch off function the
contact 20 (SW_INH) has to be connected to the stop
switch, too. Refer to the connection diagram.
Note on proportional and switching solenoids and other
wired inductive consumers
▶ The proportional solenoids must not be wired with
free-wheeling diodes.
▶ Switching solenoids at the outputs of the control unit do
not need to be connected to free-wheeling diodes.
▶ The electronics may only be tested with the proportional
solenoids connected.
▶ Other inductive loads that are in the system but not
connected to the controller must be connected to free-
wheeling diodes. This applies to relays (e.g. for
de-energizing the controller) that have the same supply
as the controller, too.
Intended use
▶ The controller is designed for use in mobile working
machines provided no limitations / restrictions are made
to certain application areas in this data sheet.
▶ Operation of the controller must generally occur within
the operating ranges specified and released in this data
sheet, particularly with regard to voltage, current,
temperature, vibration, shock and other described
environmental influences.
▶ Use outside of the specified and released boundary
conditions may result in danger to life and/or cause
damage to components which could result in
consequential damage to the mobile working machine.
Improper use
▶ Any use of the controller other than that described in
chapter „Intended use“ is considered to be improper.
▶ Use in explosive areas is not permissible.
▶ Damage resulting from improper use and/or from
unauthorized interference in the component not
described in this data sheet render all warranty and
liability claims void with respect to the manufacturer.
