FEATURES
B. In places or on surfaces where a loss of wheel grip could be hazardous, for example on
wet grassy slopes.
C. If the controller of other crucial components are known to require repair. In the event of
the wheelchair moving in an unexpected way RELEASE THE JOYSTICK. This action
will stop the wheelchair under any circumstances.
2. Although the VR2 control system is designed and manufactured to be extremely reliable
and each unit is rigorously tested, a system malfunction is always a possibility (however
with a small probability). Under some conditions the system may detect a malfunction, the
controller will (for safety reasons) stop the chair instantaneously. If the physical impairments
of the user are such that a sudden braking action could result in a fall from the chair, it is
imperative that a restraining device such as a seat belt be purchased and installed with the
chair. Restraining devices should be used at all times when the wheelchair is in motion.
DRIVE MOTORS
Note: The motors are equipped with an internal parking brake.
The PEV incorporates two 4-pole 24 VDC, high torque motors with automatic braking and
manual release. The brakes engage within two seconds of the joystick being placed in the
neutral position. The brakes will release immediately when the joystick is moved in any
direction.
When the power on the wheelchair is turned off (the controller turned off), the electric lock
brakes can be released manually by moving the release lever on the front of the chair. When
lever is in this position the chair is able to move freely without the use of the motors.
As a
safety precaution, the wheelchair will not operate when the brake is being held in the
manual release position.
ELECTRIC WHEEL LOCK RELEASE
Move the lever to the left (when facing) to
disengage and right (when facing) to engage.
