Technical data of the CANBus interface card
Maximum current which each channel can generate is 100 mA. Each channel output is protected against short
circuit towards ground and towards voltage supply. Termination resistor is already mounted on the CANBus
interface card but it can be removed, if necessary.
The CANBus interface card pin-out is described at section 5.4.4.
17.3. Wiring of the outgoing actuator cables
Please refer to section 10.2.
17.4. Connection to FPT engines through CANBus interface
Common-rail FPT engines with CANBus interface are equipped from factory with a 6 poles Superseal
connector labelled JD. Standard procedure is to simply connect the throttle CANBus cable to connector JD.
In case the engine doesn’t respond correctly to the command station, typical case is the engine that doesn’t
accelerate regularly, make the following controls:
Operation must be done with the electronic control switched off:
verify with a multimeter that the
impedance between terminals JP4.4 and JP4.5 of the CANBus PCBoards on the actuator is = 60 ohm
or similar (see section 5.4.4.). In case of different values, contact either Flexball or the FPT dealer.
Verify that the setting of the CANBUS CONVERTER MODULE is correct.
The CANBUS
CONVERTER MODULE is part of FPT installation equipment and, depending on the type and on the
age of the FPT motor, it is described by:
1. FPT Norm A0XX for new engines with ECU - EDC7UC31
2. FPT Norm A049 for all the other engines
Refer to one of the two installation schemes reported in the following page and more specifically to the
FPT installation manual to set correctly the CANBUS CONVERTER MODULE.
A wrong setting of dip-switches of the CONVERTER MODULE can cause communication problems
between FPT ECU and Flexball control system.
1. Voltage - CANBUs converter box 5802124646 according to FPT Norm A0XX (new engines)
Micro switch B4, here shown with tag “4”, must
be switched in OFF position in order to allow
CANBus communication between Flexball
Electronic Command System and FPT engine.
