Mx2+ Control Mode - Permobil SmartDrive MX2+ User Manual

It should be noted that the button must be pressed and held for longer than (1) second before it is registered as a button hold,
at which point the drive unit motor will start to drive . If it is released before this amount of time has lapsed, it will be registered
as a button press only and deactivate the power assist [if driving] or cycle power assist OFF from the SwitchControl [put it in
the standby state] .
While driving, steering is still done by pinching on the handrims of the wheelchair . If the speed seems to increase at a rate or
can get to a speed the is faster than you feel comfortable, change the Acceleration and Wired Max Speed to values that are
just right for you and your wheelchair skills . These settings can be changed in the "Settings" section of the SmartDrive MX2+
app on the PushTracker E3 .
Changing the SwitchControl Mode, the Wired Max Speed and / or Acceleration without the PushTracker E3 will require the use
of the PushTracker mobile (smartphone) app on a phone / device .

MX2+ Control Mode

[if used with PushTracker E3]
MX2+ is the default control mode for power assist when used with the PushTracker / E3 [see the separate PushTracker / E3
User's Manual provided for details on changing modes] . This amazing operation allows you to push around as much as you
want, and then quickly and easily get the power that you need for all situations . Operation of this mode is ideal for weaker
pushers as it allows for motor activation at the tap of the wrist . Additionally, this and all control modes can also always be used
with SpeedControl / SwitchControl .
To activate power assist to drive in this mode, with the power assist ON and wirelessly connected, performing a DOUBLE tap by
the PushTracker / E3 worn arm will begin the motor . This will begin driving the wheelchair forward at the Acceleration rate set
in the PushTracker / E3 [see PushTracker / E3 User's Manual] . While the speed is ramping up, performing another SINGLE tap
will hold the current speed . So the SmartDrive will continue to drive, or coast, at the speed that is reached when the SINGLE
tap is performed . This is called setting your coast speed . The power assist will continue to drive at this coast speed until a
DOUBLE tap is performed / sensed or the power assist is turned OFF .
While this mode is able to start driving you from rest, it also can be activated if you are already moving where it will quickly
catch up to your speed and begin to accelerate from there . This means that you are able to give your wheelchair a quick push
to get going, then DOUBLE tapping the PushTracker / E3 will immediately activate the SmartDrive to start ramping from the
speed that you were able to reach from the push, until a SINGLE tap is performed to cruise or another DOUBLE tap is done to
deactivate the motor .
This all might sound complicated, but it is actually very simple . Any DOUBLE tap will either activate and start ramping up the
motor speed or deactivate it [if already driving], and a SINGLE tap while the motor is driving will set your coast speed [latch
your current speed] .
Steering is still done by pinching on the handrims of the wheelchair . The motor will be able to ramp up its speed at the
Acceleration set in the PushTracker / E3, all the way up to the Max Speed that is also set in the PushTracker / E3 [see the
separate PushTracker / E3 User's Manual for changing these] . So if the speed seems to increase at a rate or can get to a speed
the is faster than you feel comfortable, change the Acceleration and Max Speeds to values that are just right for you and your
wheelchair skills .
As always, quickly pressing and releasing the SpeedControl dial / SwitchControl button [even in standby] will deactivate the
motor [if driving] . Another less preferred option is pressing the Power Assist button on the PushTracker / E3 which will also
deactivate the driving and turn power assist OFF .
If you are coasting [motor is already driving at a set speed from a SINGLE tap] and you wish to increase coast speed, there are
a couple ways to do this . If you are able to perform a push to get going at the desired faster coast speed, then performing a
SINGLE tap will cause the motor to latch and set the coast speed to your current speed . The second way that doesn't involve
a push is to perform a DOUBLE tap to first deactivate the motor, then wait at least one (1) second to perform another DOUBLE
tap to start the motor to ramp its speed again .
WARNINGS:
If any malfunctions or activation / deactivation / acceleration issues are experienced with the SmartDrive, cease use of
-
the device and contact Customer Support for assistance.
Any time the motor is already driving and a SINGLE tap is performed, the coast speed will be set to your current
-
speed. If you are going down a decline, causing you to descend at a speed faster than the set coast speed [motor is
free-wheeling], a SINGLE tap will set the coast speed to your current faster speed. Consider switching the power assist
OFF [via SpeedControl, SwitchControl and PushTracker/ E3] before descending down a slope to prevent this.
- The acceleration of the SmartDrive could possibly cause the wheelchair to tip over backwards, causing injury. It is
recommended that the user lean slightly forward to prevent this tipping and to set the Acceleration to a rate that
doesn't make this possible.
