PG DRIVES TECHNOLOGY NEWVSI TECHNICAL MANUAL – WARNING SUMMARY
SK80151-1 59
1 Introduction
This section summarizes all of the very important warnings that appear throughout the text of this manual. Do not install, maintain
or operate the newVSI controller without reading, understanding and observing the following warnings. Failure to observe these
warnings could result in UNSAFE CONDITIONS for the user of a wheelchair or affect the reliability of the controller. PG Drives
Technology accepts no liability for losses of any kind arising from failure to comply with any of the conditions in the warnings listed
below. Failure to observe these warnings will invalidate the newVSI warranty.
The wheelchair manufacturer may wish to use this section as a checklist, to ensure the risk areas identified below have been
addressed within their own wheelchair designs and associated documentation.
2 Warnings
2.1 Cleaning
Do not operate the controller if the vehicle behaves erratically, or shows abnormal signs of
heating, sparks or smoke. Turn the controller off at once and consult a local service agent. PGDT
accepts no liability for losses of any kind arising from failure to comply with this condition.
Chapter 1 Section 2.3.
2.2 Heat Shield
On no account should the wheelchair be operated if the heat shield is damaged or removed. PGDT
accepts no liability for losses of any kind arising from failure to comply with this condition.
Chapter 1 Section 2.4.
2.3 Precautions for Use
In the event of the wheelchair moving in an unexpected way RELEASE THE JOYSTICK. This action
will remove drive and power to the electro-magnetic brakes. Chapter 1 Section 6.
2.4 Hazards
Although the newVSI controller is designed to be extremely reliable and each unit is rigorously
tested during manufacture, the possibility of a system malfunction always exists (however small
the probability). Under some conditions of system malfunction the controller must (for safety
reasons) stop the chair instantaneously. If there is any possibility of the user falling out of the
chair as a result of a sudden braking action, it is imperative that a restraining device such as a
seat belt is supplied with the wheelchair and that it is in use at all times when the wheelchair is
in motion. PGDT accept no liability for losses of any kind arising from the unexpected stopping of
the wheelchair, or from the improper use of the wheelchair or controller.
Do not operate the controller if the chair behaves erratically, or shows abnormal signs of heating,
sparks or smoke. Turn the controller off at once and consult your service agent. PGDT accepts no
liability for losses of any kind arising from failure to comply with this condition.
Electronic equipment can be affected by Electro Magnetic Interference (EMI). Such interference
may be generated by radio stations, TV stations, other radio transmitters and cellular phones. If
the chair exhibits erratic behavior due to EMI, turn the controller off immediately and consult your
service agent. PGDT accepts no liability for losses of any kind arising from failure to comply with
this condition.
