If you know that the controller or other crucial components require repair.
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.
It is the responsibility of the chair manufacturer to ensure that the wheelchair complies with
appropriate National and International E.M.C legislation. PGDT accepts no liability for losses of
any kind arising from failure to comply with this condition.
The wheelchair user must comply with all wheelchair safety warnings. PGDT accepts no liability for losses of any kind arising from
failure to comply with this condition.
7 Safety Checks
The electronic circuits in your controller have been designed to be extremely safe and reliable. The on-board microcomputer
carries out safety checks at up to 100 times per second. To supplement this safety monitoring you should carry out the following
periodic checks.
If the controller fails any of these checks, do not use the wheelchair and contact your service agent.
7.1 Daily Checks
Joystick: With the controller switched off, check that the joystick is not bent or damaged and that it returns to the
center when you push and release it. If there is a problem do not continue with the safety checks and
contact your service agent.
7.2 Weekly Checks
Solenoid (parking) brake: This test should be carried out on a level floor with at least one meter clear space around the
wheelchair.
•
Switch on the controller.
•
Check that the battery gauge remains on, or flashes slowly, after one second.
•
Push the joystick slowly forwards until you hear the parking brakes operate. The chair may start to move.
•
Immediately release the joystick. You must be able to hear each parking brake operate within a few seconds.
•
Repeat the test a further three times, pushing the joystick slowly backwards, left and right.
