Functional Description
The batteries (two 12V or four 6V) are connected in series by bridge cables
The battery charger (CH) is connected to the machine by two connectors (C) (power connection to the batteries)
and C3 (3-way signal connection) The grey cables (terminals 1 and 2 of connector C3) are short-circuited in
battery charger CH when it is not connected to the electrical mains. If this connection is not made, all machine
functions are disabled
If the optional battery charger has not been installed, the relevant bridge must be used on connector C3.
The yellow cable (terminal 3 of connector C3) is the data cable between board EB1 and battery charger CH.
This connection is used to set battery charger charging curves directly on the machine dashboard (see User
Manual) and displays the state of the battery charger when charging, on the 3 battery dashboard LEDS:
Red LED lit = main charging phase
Yellow LED lit = equalization phase (charge completion)
Green LED lit = charging phase successfully completed
