l
In the case of an emergency while the vehicle is driving, press the On/Off button or
turn the key switch to perform an emergency stop and turn the controller off.
l
If there is a risk of collision with a person or object in close proximity, use the speed
dial to reduce the speed of the scooter.
l
If operators of the vehicle are left with limited or no mobility for any reason (for
example, because the vehicle loses electric power or breaks down), it is important
that they can still call for assistance from wherever they may be.
l
Go downhill slowly. When the vehicle drives downhill, the motors act as a dynamo
and generate energy. The controller sends the generated energy from the motor to
the battery. This charges the battery. However, if the battery is fully charged, it
cannot accept the generated energy any more. When this happens, there is a risk of
damage to the battery or an explosion. To prevent this risk, the controller forces the
vehicle to slow down until the battery can accept more energy. After this, it allows
the vehicle to speed up again. The result of this will be sudden speed changes of the
vehicle. To prevent these speed changes with fully charged batteries, turn on the
lights (if fitted) and decrease the speed of the vehicle when going downhill.
l
Operation of a vehicle on steep slopes can be dangerous. Before you drive up or
down a slope, make sure that the slope does not exceed the capability of the vehicle.
l
Make sure that the controller does not become colder or hotter than the minimum
and maximum temperatures specified in this manual.
l
Most electronic equipment is influenced by Radio Frequency Interference (RFI). Be
careful when portable communications equipment is used in the area around such
equipment. Dynamic Controls has made every effort to make sure that RFI does not
change the behaviour of the controller, but very strong signals can still cause a
problem. The vehicle manufacturer has the responsibility to make sure that the
vehicle is tested according to local EMC regulations.
l
The battery charger socket is to be used exclusively for the intended purpose.
Warranty will be voided if any unauthorised device is connected to this port.
l
When a scooter is driven uphill the controller will indicate a thermal fault if either the
controller or the motor becomes very hot. In this situation the controller will reduce
the available motor current to protect the controller and motor. It is possible with
this reduced performance, that the controller is unable to provide sufficient power to
the motor to hold the scooter on the slope and so as a safety precaution, the
controller may force the scooter to a stop with the park brake applied when the user
is attempting to continue driving. If the scooter operator observes this thermal fault
indication (same indication as Stall timeout or Overcurrent fault) the recommended
response is to immediately stop driving by releasing the throttle to neutral, then to
wait for at least 30 seconds before attempting to continue driving.
The following safety information shall also be provided to all scooter operators:
l
instructions on the interpretation of the battery gauge;
l
any special environmental storage conditions;
l
the causes of electromagnetic interference and possible effects on the scooter.
