3
Not used
4
Motor not connected or false contact on the motor
circuit. It happens for example if the motor brushes
are not touching properly on the armature or if there
are loose cables.
Check the connections of the motor, its
functionality and integrity.
5
Fault inside the controller or mass on the engine.
There may be a negative dispersion on
the motor circuit; as alternative, it is
necessary to check the regulator.
6
Fault potentiometer; it is displayed when there is no
negative potentiometer. This signal indicates that the
voltage read by the system is higher than that
provided for the speed command and it occurs, for
example, if there is no connection to the negative of
the speed command
Check the wiring of the potentiometer
and the integrity of it.
7
Temperature of the power circuit is too high; it occurs
when the temperature of the mosfets is over 75 ° C +/-
5 ° C, that is, if the machine has worked in overload
conditions, for example on high slopes for long period
or at ambient temperatures above 40 ° C. It may
happen even in case of damage to the motor
windings, which causes an abnormal current
absorption.
Wait for the temperature to fall down.
8
Segnala che si sta tentando di avviare la macchina
quando questa (o il motore) è già in movimento.
Engine already rotating when starting. It indicates that
somebody is trying to start the machine when this (or
the engine) is already working.
Stop the vehicle first and then repeat.
9
Anomaly to the microcontroller software or hardware
problem. It occurs in case of failure to circuits for
measuring the current and the load.
Try to turn off the vehicle. If the error
still appears check the controller.
