Driving up slopes and down inclines with activated rollback delay.
You can drive up and down slopes as usual whereby the motors move the e-motion wheels according to the power stage selected and the
preprogrammed power assistance. The automatic rollback delay kicks in when the wheel electronics senses the wheel rolling back against
the original direction of travel. This means that the wheels are slowed down by braking for 5 seconds thus being prevented from rolling
back. This is followed by two short signal tones and the brake function is gradually cancelled. The wheel run free after 5 seconds.
Safe travel on a slope (with activated hill-holder) depends on the total weight (=weight of the person in the wheelchair, the wheelchair,
both e-motion wheels and any other accessories), as well as the charge level of the battery. The following table shows which slopes can be
travelled safely with only a minimally charged battery.
Total weight Slope that is safe to travel
115 kg 14%
140 kg 11,50%
170 kg 9%
Activating / deactivating the rollback delay
To activate the rollback delay, push the following buttons on the remote control:
button 1 [23] (for activation in power stage 1), or
•
button 2 [22] (for activation in power stage 2). •
Push the buttons longer than 3 seconds. Activation is confirmed with a long signal tone.
If you want to switch off the rollback delay, push (depending on the selected power stage) button 1 or 2 again longer than 3 seconds.
Deactivation is confirmed with a long signal sound.
Alternatively, you can also switch off the e-motion wheels. The rollback delay is deactivated if the e-motion is switched off and on again.
Safety instructions
In case of especially steep slopes and/or very heavy wheelchair drivers, the rollback delay might not be able to prevent a slow rolling
•
back of the wheelchair.
The rollback delay is not a parking brake but only delays the wheelchair from rolling back for only a few seconds. Therefore, secure your
•
wheelchair with the parking brakes to stop on a slope.
Use the rollback delay only with sufficient battery capacity (if at least 2 LEDs are still on)!
•
The rollback delay must be reactivated each time after the e-motion wheels have been switched off •
Failure to follow these instructions can cause damage or personal injury. •
7. Automatic self switch-off
To save energy, time periods have been assigned to the e-motion wheels and the remote control after which they are switch off automati-
cally.
7.1 Automatic wheel self switch-off
The value preset at the factory for the automatic self switch off is 30 minutes.
This value can be changed with the optional remote control. With regards to this topic, please contact your specialist dealer.
7.2 Remote control (optional) self switch-off
The value preset at the factory for the automatic self switch off of the remote control display is 5 minutes. This value can be changed by
corresponding programming of the remote control. With regards to this topic, please contact your specialist dealer.
If the remote control does not find any wheel (for example, because the remote communication could not be established), it always
switches off after 5 seconds. This value cannot be changed.
8. Fuse replacement
As any electric or electronic device, your e-motion is equipped with fuse protection. The fuse responds in case of a defect and thereby pro-
tects the electronic components from lasting and expensive damages.
The fuse of the e-motion wheel is located in the electronic system inside the wheel hub. A possibly required fuse replacement, together
with a complete diagnosis of the entire electronic system may only be carried out by the authorized specialist dealer.
