S-DRIVE – OPERATION PG DRIVES TECHNOLOGY
SK76745/10
Depending on the scooter model, the throttle configuration may be one of three types - wig-wag, single-ended or Unipolar.
3.3.1 Wig-wag Throttle
In this configuration, both the speed and the direction of the scooter are controlled by the throttle. To drive forwards, push the
throttle in one direction: to drive in reverse, push the throttle in the other direction.
3.3.2 Single-ended Throttle
In this configuration, just the speed of the scooter is controlled by the throttle. When the throttle is pushed - depending on the
position of the reverse switch (refer to section 3.4) - the scooter will drive in either the forward or reverse direction.
3.3.3 Unipolar Throttle
In this configuration, just the speed of the scooter is controlled by the throttle. When the throttle is moved, in either direction, -
depending on the position of the reverse switch (refer to section 3.4) - the scooter will drive in either the forward or reverse
direction.
3.4 Reverse Switch
This switch will be fitted to the scooter if the throttle configuration is single-ended or Unipolar (refer to sections 3.3.2 & 3.3.3). The
switch is used to change between forward and reverse drive.
3.5 Speed Limiting Potentiometer
This control sets the maximum speed of the scooter. Turn the knob clockwise to increase the maximum speed setting or anti-
clockwise to decrease the maximum speed setting.
3.6 Slow/Fast Switch
This switch selects the driving mode - either slow or fast - of the scooter. You can use this switch to limit the scooter’s driving
behavior in environments where that may be desirable or necessary, e.g. if you are driving indoors or on the sidewalk.
3.7 Audible Alarm
This provides an audible warning when the scooter is being driven in the reverse direction. The alarm may also be used to signal
other conditions, such as scooter in freewheel mode.
4 Getting Ready to Drive
Check that the speed limiting control is turned to a position which suits you.
Operate the on/off switch. Either:
A TruCharge type status indicator will blink and remain on after half a second.
A single bulb (or LED) type status indicator will blink and remain on after half a second.
During the first half-second after the scooter is switched on, the controller is performing important safety checks within itself and
the rest of the scooter’s electrical system. Therefore, if you push the throttle during this time, you will not be able to drive until you
have returned the throttle to the rest position and switched the controller Off and On again.
If the scooter has a single-ended throttle, use the reverse switch to select the direction you want to drive and then push the
throttle to control the speed. If the scooter has a wig-wag throttle, push the throttle in the direction you want to drive.
If you do not push the throttle as you switch the scooter on and the status indicator flashes rapidly, then there may be a trip. Refer
to section 8 for details.
