12.2 Skwirrel II inhibits.
The following inhibits are installed in the Skwirrel II system:
1. Charge inhibit (bridge inside the charger plug)(message in the display)
This inhibit is activated if the charger is connected. It blocks the driving.
2. Flip over joystick module inhibit. (mercury switch inside the JSM module)
This inhibit will be activated as soon as the desktop JSM module is flipped over.
It blocks the driving.
3. Brake release Inhibit (switch in drive motor) (error message on display)
As soon as the brakes are mechanically released, the driving will be blocked.
4. Seat tilt inhibit (switch on the seat frame)
(only if powered seat function is mounted)
When the seat tilt is active (tilted) is not possible to move the seat elevator to the ground.
5. Powered seat elevator going up inhibit (potentiometer inside actuator)
Because the seat elevator is made out of two units: one for lifting the seat upwards and one for the
seat moving down to the ground, there are also two separate inhibits. Each actuator has its own
inhibit. If the seat elevator for going up is active, the seat elevator going to the ground is blocked
and vice versa.
Both inhibits also have influence on het driving speed. When the seat is not in its normal driving
position, the drive speed will be reduced. When the seat is close to the ground the driving is even
blocked.
6. Seat elevator to the ground. (Potentiometer inside actuator). This inhibit will block the seat tilt
function when de elevator is moved down to the fround.
7. The end position inhibit of the seat actuator. Both seat elevator actuators have build in
potentiometers which detect the end stop of the actuators. These end stop inhibits can
also be used to make the elevator stop on a required position. For instance a child is not
allowed to down to the ground completely because he or she cannot stretch the legs.
8. inhibit speed kit (switch on rear axle)
(if speed kit is mounted)
If the speed kit is not activated the speed of the wheelchair is reduced to 50%. If the speed kit is
active and the actuator has moved to it active position the inhibit switch is pushed and the maximum
speed is released.
Beside these inhibits the actuators are additionally protected against overload by a current limit
system. These current limits are also programmed in the software settings.
NOTE:
The inhibit settings are programmed in the OEM area of the wheelchair software. These settings can
only be changed by special authorized persons who know all the ins and outs of the wheelchair
programming. Please contact Huka B.V. for further information.
