7 Controls System

7.1 Electronics Protection System

The scooter electronics is fitted with an overload protection.
If the drive is severely overloaded over a long period of time
(for example, when driving up a steep hill) and especially
when the ambient temperature is high, the electronic system
could overheat. In this case the scooter performance is
gradually reduced until it comes to a halt. The status display
shows a corresponding error code (refer toError Codes And
Diagnostic Codes). By switching the power supply off and
back on again, the error code is cleared and the electronics
is switched back on. It can however take up to five minutes
until the electronics has cooled down enough for the drive
to restore full performance again.
If the drive is stalled by an insurmountable obstacle, for
example, a curb or similar which is too high, and the
driver attempts driving for more than 20 seconds against
this obstacle, the electronics automatically switches off to
prevent the motors from being damaged. The status display
shows a corresponding error code (refer to Error Codes And
Diagnostic Codes). By switching off and back on again, the
error code is cleared and the electronics is switched back on.

7.1.1 The main fuse

The entire electrical system is protected against overload
by two main fuses. The main fuses are mounted on the
positive battery cables.
38
A defective main fuse may be replaced only after
checking the entire electrical system. A specialized
Invacare provider must perform the replacement.
You can find information on the fuse type in 12
Technical Data, page 56.

7.2 Batteries

Power is supplied by two 12 V batteries. The batteries are
maintenance-free and only need regular charging.
In the following, you find information on how to charge,
handle, transport, store, maintain, and use batteries.

7.2.1 General Information on Charging

New batteries should always be fully charged once before
their first use. New batteries will be at their full capacity
after having run through approx. 10 - 20 charging cycles
(break-in period). This break-in period is necessary to
fully activate the battery for maximum performance and
longevity. Thus, range and running time of your mobility
device could initially increase with use.
Gel/AGM lead acid batteries do not have a memory effect
as NiCd batteries.

7.2.2 General Instructions on Charging

Follow the instructions listed below to ensure safe use and
longevity of the batteries:
• Charge 18 hours prior to initial usage.
