Invacare® TDX® SP2 Series
7 Controls System
7.1 Controls Protection System
The wheelchair controls system is equipped 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 controls system
could overheat. In this case, the wheelchair performance is
gradually reduced until it stops. The status display shows a
corresponding error code (refer to the user manual for your
remote). By switching the power supply off and back on
again, the error code is cleared and the controls system is
switched back on. It can however take up to five minutes
until the controls system 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 controls system automatically switches off to
prevent the motors from being damaged. The status display
shows a corresponding error code (refer to the user manual
of your remote). By switching off and back on again, the
error code is cleared and the controls system is switched
back on.
A defective main fuse may be replaced only after
checking the entire controls system. A specialized
Invacare provider must perform the replacement.
You can find information on the fuse type in
.
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 approximately 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
like 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.
•
We recommend charging the batteries daily after every
discharge even after partly discharge, as well as each
night over night. Depending on the level of discharge,
it can take up to 12 hours until the batteries are fully
charged again.
•
When the battery indicator reaches the red LED range,
charge the batteries for at least 16 hours, even if the
display reads that the charge is complete.
•
Try to provide a 24 hour charge once a week to make
sure that both batteries are fully charged.
