2.18 Programming – Introduction
Programming should only be conducted by healthcare
professionals with in-depth knowledge of PGDT control
systems. Incorrect programming could result in an unsafe

responsibility for losses of any kind if the programming of
the control system is altered from the factory pre-set values.
Chapter 3 section 1.
2.19 Safety Fences
PGDT accepts no liability for losses of any kind if the chair
manufacturer does not specify appropriate safety fence
values for a particular wheelchair application. Chapter 3
section 1.4.
2.20 Brake Fault Detect
This parameter should only ever be set to off if there are
no electrical brakes fitted to the wheelchair. Chapter 3 section
7.9.
2.21 Current Limits
The values in the table, VR2 Current Management, should
never be exceeded. Doing so will invalidate the warranty
and affect the long term reliability of the control system.
Chapter 3 section 8.1.
2.22 Motor Compensation
Never exceed the 70% relationship described above.
The chair manufacturer is responsible for ensuring that the
control system is matched to the motor resistance. Failure
to do this may result in poor control characteristics, which

any kind arising from failure to comply with this condition.
The chair manufacturer is responsible for always ensuring
