PG DRIVES TECHNOLOGY NEWVSI TECHNICAL MANUAL – PROGRAMMING
SK80151-1 35
1 Introduction
This chapter gives an overview of the programmable parameters within the newVSI controller. The newVSI can be programmed
with a PP1a handheld programmer, a DTT handheld programmer or a PG Drives Technology PC Programmer.
This chapter does not give details of how to make adjustments, for these details please refer to the relevant documentation for
the programmer you are using.
Programming should only be conducted by healthcare professionals with in-depth knowledge of
PGDT controllers. Incorrect programming could result in an unsafe set-up of a wheelchair for a
user. PGDT accept no responsibility for losses of any kind if the programming of the controller is
altered from the factory pre-set values.
1.1 Handheld Programmers
The PP1a and DDT are hand-held units which can be plugged into your controller to alter the controller’s programming. Your
wheelchair distributor or service agent or wheelchair manufacturer will be able to program your controller for you.
The PP1a and the DTT handheld programmers are intended to give dealers and therapist access to the programmable
parameters which can be used to adjust the wheelchair to an individual user. These parameters are:
Acceleration Sleep Timer
Deceleration Joystick Throw
Turn Acceleration Invert Joystick
Turn Deceleration Steer Correct
Forward Speed Bleep Volume
Reverse Speed Reverse Alarm
Turning Speed Speed Adjust
Torque Profiles
Tremor Damping
Power
The PP1a and DTT can also be used to read the System Log and Read Timers. For details of how to use the PP1a and DTT with the
newVSI, read the appropriate user guide before you use it.
1.2 PC Programmer
There are three versions of the PC Programmer – one for dealers and therapist which gives the same access level as the PP1a
handheld programmer, one for wheelchair OEMs which gives access to all standard newVSI controller parameters and one for
use by OEM’s on their production lines. These are known as Dealer, OEM and Manufacturing respectively.
For details of how to use these software packages with the newVSI, refer to the documentation supplied with the software.
1.3 Safety Fences
Limits (or fences) can be applied to some dealer accessible programmable parameters. These limits are known as safety fences
and are programmed by PGDT when the controller is manufactured. The purpose of these fences is to prevent the wheelchair
being programmed to be too fast, or too severe in its acceleration or deceleration. The parameters which can have fences
applied to them are:
Forward Speed
Reverse Speed
Turning Speed
