Invacare® Esprit Action® 4 NG

6 Controls system

6.1 Controls protection system

The wheelchair controls system 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 controls system
could overheat. In this case, the wheelchair performance is
gradually reduced until it comes to a halt. The status display
shows a corresponding error code (refer to Control unit and
Quick assistance on system failure chapters, ALBER esprit
user manual). 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 Control unit and
Quick assistance on system failure chapters, ALBER esprit
user manual). By switching off and back on again, the error
code is cleared and the controls system is switched back on.
