3.1.10 Deep discharge indicator
Fig. 7
Deep discharge
indicator
The machine is equipped with a deep
discharge indicator to prevent deep dis-
charge of the batteries. The deep dis-
charge indicator is integrated in the
electronics.
Battery charging state indicator
During operation, the electronics of the
machine indicate the discharge status
of the batteries via one red LED
(Fig. 7/1) and three green LEDs
(Fig. 7/2).
If all three green LEDs light up, the bat-
teries are fully charged. With increasing
discharge, the LEDs extinguish one af-
ter the other from right to left. When the
last green LED has extinguished, the
red LED starts flashing (advance warn-
ing of imminent shut-off). After a period
of time, the red LED lights up perma-
nently and signals “battery empty” as
the battery status. Shortly afterwards,
the drive motor is automatically
switched off to protect the battery from
deep discharge.
The machine can only be restarted with
a charged battery.
