2 Immobilizing the Wheelchair
2.1 Prevention of Unauthorized Use
TÜV requires that the wheelchair must have a means of preventing unauthorized
use. This can be implemented electronically using the button and joystick sequence
detailed in Chapter 1 section 3.2. This method of locking has been chosen to prevent
problems arising from lost keys.
Alternatively, an external switch which interrupts the battery or solenoid brake circuit,
or provides a drive inhibit, can be fitted.
2.2 Charger Interlock
ISO 7176-14 requires you to provide a means of preventing the use of the wheelchair
while the batteries are being charged. The charger socket and on-board charger
connection fitted to the PG Drives Technology VR2 control systems include an inhibit
facility. Refer to section 9 for details.
Contact PG Drives Technology if you need advice.
The chair manufacturer is responsible for providing a means
of preventing the use of the wheelchair while the batteries
are being charged. PGDT accepts no liability for losses of
any kind arising from failure to comply with this condition.
