2 Before use

Risk of injuries and damage

• Do NOT install, maintain or use this product unless you have read and fully understood all

instructions in this manual and all relevant manuals regarding the wheelchair equipped with

this product.

• Do not try to open or disassemble the console in any case - there are no user-serviceable parts

inside.

• In case of doubts or questions, do not hesitate to contact your local specialist dealer, your care

provider, or your technical adviser to help you with this.

2.1 General safety instructions

Keep the following general warnings in mind during use:

• The operating consoles have been tested for electromagnetic compatibility on typical,

representative vehicles and comply with the appropriate EMC standards:

EN 12184: 2014, ISO7176-21: 2009.

• Nevertheless, sources of electromagnetic field may influence the driving performance of your

wheelchair, like the fields of mobile phones, power generators or high-power energy sources.

On the other hand, the electronics of your wheelchair can affect other electronic appliances

too, like alarm systems of shops and automatic doors. We therefore advise you to check your

operating console / wheelchair regularly for damage and wear, since these may enlarge the

interference.

• Be aware that the surface of the operating console may get very hot due to solar radiation or

heating devices. Be careful when touching.

• Make sure that the controller does not become colder or hotter than the allowed minimum

and maximum temperature, see the wheelchair user manual.

• Before switching the wheelchair on, be aware of your environment/situation. Adjust your

speed accordingly before driving off. We advise you to use the slowest speed setting to drive

indoors. For outdoor driving you can adjust the speed to a suitable speed at which you feel

comfortable and safe.

• Do not touch the connector pins. If you touch the pins, they can become dirty, or they can be

damaged by electrostatic discharge.

• If the wheelchair has not been fitted with a hand guard for the operating console, be aware

that your hand will not be protected from crushing, for example while manoeuvring towards a

table.

• The XLR connector on the controller is to be used exclusively for the intended purpose of

charging the battery. The warranty will lapse if any unauthorized device is connected to this

port.

• Make sure that the battery charger that is used with the vehicle has a drive-inhibited function

that is correctly connected for use with the controller. This drive-inhibited feature is intended

to prevent the chair from driving while the battery is being charged. If you are not sure, ask

your dealer.

• Immediately turn the controller off and consult your service agent if the vehicle:

o is damaged;

o does not behave the same every time;

o does not respond normally, the way you expect it to;

WARNING

Vermeiren is responsible for software updates/repairs. For adaptations in the software,

contact Vermeiren, see our website http://www.vermeiren.com/

4 Operating console functions

The operating console enables you to control all driving components as well as the motors to

adjust your body position. For your own safety, and to prevent that the wheelchair gets damaged,

movements are monitored by the electronics. This may result in block of movement, speed

decrease or complete stop.

4.1 Switching ON / OFF

Put the joystick in the neutral (central) position before pressing the ON/OFF button.

If the console is switched on with the joystick out of the neutral position, the wheelchair will

not drive. Release the joystick (return to neutral) within 5 seconds to unlock the drive. If the

joystick is not released within 5 seconds, the fault turns into a Module fault which is

indicated by the red blinking LED in the ON/OFF button. The wheelchair will not drive. To

clear the Module fault, release the joystick and switch the operating console OFF and then

ON again.

• To switch the operating console ON, press the ON/OFF button once.

The start screen is displayed for a few seconds, after which the

operating screen appears. The LED (status indicator) in the ON/OFF

button goes on. When it turns green, the operating console is ready

for operation. When the LED starts blinking in red, there is a failure,

see §4.2 and §5.

• To switch the operating console OFF when it is ON: press the button

once.

The operating console will power down and the status indicator goes

out.

Switching ON/OFF

4.1.1 Emergency stop

If you need to stop a driving or body-positioning movement quickly, press the ON/OFF button to

perform an EMERGENCY STOP. The wheelchair will come to a halt quickly.

4.1.2 Sleep mode

The operating console will go into sleep mode after a period of inactivity (default 5 minutes).

When the system sleeps, it is partially turned off to reduce energy consumption.

To reactivate the operating console, press a button or move the joystick.

4.2 Failures and blocks

When the operating console is powered and a failure

appears, the indicator of the ON/OFF button starts blinking

in red, see picture. The number of blinks indicates the fault

code. For a few seconds, a triangle with fault code (A) is

displayed. The ON/OFF button will keep blinking.

In case of a failure, one or all functions of the operating

console are blocked. This is indicated by the “forbidden”-

symbol and the yellow warning bars (B).

Failure indication and drive inhibited

The status is indicated by a small symbol (C) in the top corner of each screen.
