If you have any doubts about the suitability of a particular motor type or you need advice on measuring motor impedance,
contact PGDT.
The chair manufacturer is responsible for ensuring that the controller is matched to the motor
resistance. Failure to do this may result in poor control characteristics, which in extreme
instances can make a chair uncontrollable and potentially unsafe. PGDT accepts no liability for
losses of any kind arising from failure to comply with this condition.
The chair manufacturer is responsible for always ensuring that any replacement motors or
gearboxes are fully compatible with the originals that the controller was designed to match.
Failure to do this may result in poor control characteristics, which in extreme instances can make
a chair uncontrollable and potentially unsafe. PGDT accepts no liability for losses of any kind
arising from failure to comply with this condition.
Users must not move a controller from one chair type to install it on a different chair type.
controllers with different part numbers may have both hardware and software differences to
ensure that they are compatible with the electrical and dynamic characteristics of their specific
target vehicles. The characteristics of one type of controller may not be compatible with a
different, unauthorized chair. Failure to observe this warning could result in an unsafe set-up for
the wheelchair user and may create a fire hazard depending on the motors, wiring, connectors
and circuit breakers installed on the unauthorized chair. PGDT accepts no liability for losses of
any kind arising from failure to comply with this condition.
6 Batteries
The controller is designed for operation with 24 V lead acid batteries. The batteries may be wet or gel electrolyte types.
Contact PGDT for advice on battery selection.
7 Battery Charging
All newVSI controllers have a battery charging socket mounted on their front face for connection to an off-board charger.
While the battery is being charged the newVSI’s TruCharge display will continuously ripple or step upwards.
The maximum permissible charging current is 12A rms. Only chargers fitted with Neutrik NC3MX plugs should be connected into
the newVSI controller. The pin connections of the socket are as below.
Pin Connection
1 Battery Positive
2 Battery Negative
3 Inhibit
To prevent the wheelchair from driving while the charger is connected, pin 3 must be linked to pin 2 inside the charger’s plug.
Do not exceed the maximum charging current of 12 A rms. Always use an off-board charger fitted
with a Neutrik NC3MX plug. Failure to observe these conditions could result in poor contact
resistance in the charger connector resulting in overheating of the charger plugs. This presents a
potential burn hazard for the user. PGDT accepts no liability for losses of any kind arising from
failure to comply with this condition.
