On Deflecting the joystick North will result in Reverse drive.
Off Deflecting the joystick North will result in Forward drive.
4.4 Steer Correct
This parameter compensates for any mismatching of motors to ensure that the wheelchair drives directly forward when the
controller’s joystick is being pushed directly forward.
It is normally set to zero but may be varied from -9 to +9 in increments of 1. If the chair is veering to the left, you should increase
the setting. If the chair veers to the right, decrease the setting.
4.5 Switch Bleep Volume
Switch Bleep Volume sets the volume of the audible feedback given whenever a button on the newVSI is operated.
Adjustable between 0 and 10 in steps of 1.
The higher the value, the louder the audible feedback. When set to 0 there will be no audible feedback.
4.6 Speed Adjustment while Driving
This parameter sets whether the newVSI’s speed/profile buttons are active while the wheelchair is being driven. The parameter
can be set to on or off.
On Means the buttons are active while the wheelchair is being driven, so the user can make maximum speed
setting adjustments (or select a different drive profile) while actually moving.
Off Means the buttons are not active while the wheelchair is being driven, so the joystick must be released and
the wheelchair at rest before maximum speed setting adjustments (or different drive profile selections) can
be made.
4.7 Service Timer
The service timer function is used to set the number of hours that need to elapse before the controller notifies the user that a new
service is required.
The service timer can be programmed between 0hrs (off) and 10000 hours.
When the service timer is active the 5 LEDs in the battery gauge will flash 100ms on, 1 second off, for the first 20 seconds after the
controller is switched On. The service reminder is reset by incrementing the Service Timer in the PC Programmer.
5 Battery Parameters
5.1 Cable Resistance
This parameter should be set to the total value of the electrical resistance of wires between the batteries and the newVSI body.
This parameter ensures the TruCharge battery gauge gives an accurate reading under all driving conditions.
Adjustable between 0 and 255 mOhms in steps of 1 mOhms.
The value should take into account the electrical resistance in both the positive and negative connections.
The battery wires in the newVSI cable have a typical electrical resistance of 4.6mOhms/metre. Therefore, if the newVSI has a 1.2m
cable, the Cable Resistance setting must be at least:
(1.2 x 4.6mOhms) x 2 = 11 mOhms.
To this value you must also add the resistance of the wheelchair wiring between the batteries and the newVSI connectors.
