CHARLY OPERATING INSTRUCTIONS

7. Exhaustive discharge protection

The vehicle's battery can be damaged when it is discharged completely. The exhaustive
discharge protection system integrated into the electronic circuit will switch the motor OFF when
the charge is low.
CAUTION
A sudden failure of the motor may cause disturbances in road
traffic.
Make certain that the battery always has a sufficient charge.
CHARLY has an exhaustive discharge protection for the batteries. The electronic circuit will
switch the motor power supply OFF whenever the battery voltage falls below a defined value.
CHARLY stops.
Charge the batteries immediately!
You cannot drive on. LEDs 1 and 2 will continue flashing for up to 5 minutes after the master
switch is OFF.
Attention! The exhaustive discharge protection can also switch the system OFF in the event of
a short voltage cut-off between battery and vehicle. Insert a new 35 A fuse in this case. If this
does not help, ask the dealer to correct the fault.

8. Automatic shutdown

The motor control switches the motor power supply OFF after about 5 minutes when CHARLY
is parked without turning the master switch OFF.
Horn and lights are still operational.
Before driving on, turn the master switch OFF and ON again.

9. Overload protection

Motor output is reduced by half to protect the electrical installation when CHARLY is
overloaded (e.g., by driving up long gradients). Full output is available again after waiting a
sufficient time to allow the electronics box to cool down.
