2.1 - ACTIVATION OF CONTROLS
The controls must be validated by a 'Enable Switch' system to activate the different
movements.
The 'Enable Switch' system depends on the machine configuration and will consist of one of
the following :
• Joystick handle.
• Pedal.
• Validation button.
2.2 - ON-BOARD ELECTRONICS
The machines are equipped with a specific calculator configured for the machine's
functionalities.
Poor knowledge of the characteristics and operation of the machine can lead the operator to think that a
normal safety operation is a malfunction.
Do not interchange the calculator between machines to avoid losing the machine’s parameters, settings
and calibrations.
