DYNAMIC DL CONTROLLER
When the ON/OFF button is pressed, a bleep tone can
be heard from the controller and the battery charge
indicator will light up confirming that power is switched on
and the wheelchair is ready to move.
The Speed Control Knob on the rear of the Controller
enables you to reduce the maximum speed at which the
wheelchair can travel when the joystick is fully deflected
in any direction. The more you turn this knob
anticlockwise, the lower will be the maximum speed, no
matter how far you push or pull the joystick.
The Battery Charge Indicator (Fig. 2) lights up when the
ON/OFF button is pressed into ON. It gives you updated
information as to how much charge approximately is left
in the batteries, so that you can estimate how much
further you can drive before you have to recharge the
batteries. The reading will drop while the wheelchair is
being driven, and increase after the wheelchair has been
at a standstill for a few seconds. This is quite normal, and
it is best to check the indicator while the wheelchair is
stationary.
The battery charge indicator also informs you of any fault
condition when one or several of its lamps begin to flash.
Display flashing slowly: the wheelchairs moves slowly,
but with sluggish response and reduced speed indicates
the batteries are discharged below the critical level or possible controller or motor fault.
Display flashing rapidly: (twice per second) and the wheelchair not moving also indicates the batteries
are discharged below the critical level or a possible controller fault.
In both cases it is advisable to check and re-charge the batteries, if the fault indication persists, contact
the authorised INVACARE dealer.
On the rear face of the controller you find the Battery Charging Socket. Underneath is a special socket for
the connection of Programming Instruments if and when the response characteristics of the wheelchair
(acceleration, deceleration, damping etc.) are to be further adjusted to your needs (Consult your
authorised INVACARE dealer).
