Additional Fitting Hints
1.
The Powerpack is normally fitted between the two horizontal tubes of the wheelchair frame. If this is not
possible, it can be fitted between vertical or diagonal tubes.
2.
The angle that the Powerpack is mounted at is important in terms of performance. To check that the
Powerpack is mounted at the correct angle, measure from the bottom of the crossbar housing to the
ground (to do this the Powerpack should be fitted to the wheelchair and on even terrain). Ideally, this
distance should be between 12.5 to 16.5 cm (5 to 6.5 inches approximately). If this distance is less than
12.5 cm, the front of the Powerpack is too low. This is most likely to occur on wheelchairs with very small
wheels or a particularly low frame. If the distance is greater than 16.5 cm, the front of the Powerpack is
too high. In either case, TGA have a range of adaptations to facilitate the optimum positioning of the
Powerpack on your wheelchair. The above is only a guide and the distances are approximations. If you
are in any doubt, please contact TGA.
Controls
1.
ON/OFF LIGHT & BATTERY CONDITION INDICATOR - At the top of the handlebar control you will see a
small light (Fig 5A). This is a multi-function light and will come on when the ON/OFF key (Fig 5D) is
switched to on indicating the machine is ready for use. In addition it has another function which is to
indicate the state of charge of the battery. When you switch on you will notice the light go through a
sequence of colours, starting at red through amber to green, indicating the battery is fully charged.
Providing the battery is fully charged the green will stay on until the battery charge condition drops to a
level that will change the light to amber, indicating that the battery should soon be recharged. At the final
stage of the light sequence the amber will change to red indicating the battery has a very low charge and
should be recharged at the very earliest opportunity. The third function of the light is to provide a fault
code indication. This will operate if the Powerpack has a fault or is overloaded. The machine will cutout
and the light with flash a certain sequence. To re-set, switch off, wait a few seconds and switch on again.
If the fault has not cleared, contact your dealer or TGA.
2.
PRESET SPEED CONTROL - Immediately under the light is a small round control which is the Preset Speed
Control (Fig 5B). This will control the maximum speed of the Powerpack by turning in a clockwise direction
to increase speed and anticlockwise to reduce speed, particularly useful when going around shops or other
confined spaces where a high level of control is needed.
3.
SPEED CONTROL LEVER - Whilst the Preset Speed Control will limit the top speed of the Powerpack, the
speed control lever will progressively control the speed up to the preset limit (Fig 5C). The more you push
the lever down with your thumb the quicker you will go. An alternative use for the lever is to preset your
top speed with the preset control, then use the lever as a button simply by pressing from top to bottom in
one movement. The electronics will still provide a smooth take off.
4.
ON/OFF KEY - Situated under the speed lever this is simply an ON/OFF switch with removable key (Fig 5D).
The key will be in a vertical position for off. Turn clockwise for on. Never leave switched on when not in
use or with someone sitting in an unattended chair. When leaving the chair always take the key with you.
5.
DIRECTION SWITCH - Fitted on the left hand side of the hand control on powerpacks with the reverse
upgrade. (Fig 5F). The direction switch controls the direction that the powerpack will operate (forward and
reverse). With the ignition key switched off simply press the direction switch forward to operate the
powerpack forward, and in the reverse position to operate the powerpack backwards. N.b if using the hand
control on the left hand handlebar the direction switch can be removed and rotated so that it is facing
inwards.
