Fantuzzi FDC 25 K7: what is the LMS Plus system?
According to its manual, LMS Plus is the control system of FDC machines such as the FDC 25 K7, FDC 25 J7 and FDC 18 K6, built on a multiple CAN bus network that links units each dedicated to one function, as recorded at HIT SRL. The same manual states that its single display is not needed for the machine to work, as logged by the HIT SRL technical desk. It lists signal testing, operator management by badge, boom and spreader control, speed control integrated with transmission and engine, a malfunction black box for sensor faults, overloads and bypass use, and an operative black box for the containers moved, as recorded by the HIT SRL technical desk.

Fantuzzi FDC 25 K: which functions are on the LMS Plus joystick?
On FDC machines with LMS Plus the joystick is hydraulic with electrical buttons, according to the LMS Plus documentation, as logged by the HIT SRL technical desk. The same documentation gives twistlock lock and unlock and side shift on the FDC 18 K, 20 K and 25 J, with spreader rotation added on the FDC 25 K, as recorded at HIT SRL. The layout is that of the LMS Plus FDC V5.x operator manual, as recorded by the HIT SRL technical desk.

Fantuzzi FDC 25 J7: how are LMS Plus V72 calibrations made?
According to the LMS Plus V72 service manual, calibrations are made only from the LMS Plus display with an external keyboard, the HIT SRL technical desk notes. The menu sets the spreader configuration, the 20-40 foot timeout and the weight system, and covers load, transmission, engine, pedal and fuel calibration, speed parameters, counters and the exchange of calibrations and capacity charts with a PC, as set out in the HIT SRL technical cards. This is the procedure of that manual for the FDC 25 J7, as recorded by the HIT SRL technical desk.

Fantuzzi FDC: what is the Advanced Powertronic System?
According to its manual, the Advanced Powertronic System V5.x is a control system produced from 2003 for machines with electronic engines and mechanical or electronic transmissions, as recorded at HIT SRL. The same manual has it receive pedal, speed-selector and accelerator signals and drive the transmission, by direct valve activation or a secondary CAN line, and the engine over CAN (SAE J1939); the primary CAN line serves the Eco-CAN display, as logged by the HIT SRL technical desk. The manual lists it for the FDC 25K with spreader, the FDC 280 with forks, the FDC 320 and 420 with forks or spreader and the FDC 450 with spreader, as recorded by the HIT SRL technical desk.

Fantuzzi FDC 550 G5: what does the Digicontrol system consist of?
Digicontrol, according to the Digicontrol documentation for the FDC 550 G5, is a multiple CAN bus network with PLCORE units in cab, truck and spreader, an emergency CAN gateway, a secondary CAN for J1939 engine control units and a colour display that the machine can work without, as HIT SRL's technical desk reads it. The manual describes it as the system of the high-end Fantuzzi stackers, the HIT SRL technical desk notes. Its display, in the 2007 operator manual, shows speed, actual and desired gear, mast angle and length, fuel level, coolant temperature and alarms, and during handling the spreader status, container weight, maximum weight and residual lift capacity, as recorded by the HIT SRL technical desk.
