3.8. EMERGENCY BUTTON

This is a safety device which allows the user to stop the machine in an emergency situation. It
consists of 2 magnetic sensors fixed to the machine display, which form a NC contact when the
emergency stop device is correctly positioned on the control panel during exercise.
If a user is in difficulty and press the emergency device from the control panel or pull the emergency
rope, the NC contact is opened then the CPU/ARM board shows the message:
LED display: "PRESSA KEY"
VISIO display: "TOUCH THE SCREEN"
Moreover the CPU/ARM board sends a signal to the Drive which cuts off the power supply to the
tread belt motor, halting the machine.

3.9. BELT MOTOR

An asynchronous three-phase motor which, by means of a pulley and poly-v belt, turns the driving
roller of the tread belt. Is equipped with a normally-closed thermal cut-out which opens when the
temperature exceeds a preset threshold, in order to safeguard the integrity of the motor. The thermal
signal reaches the driver as a NC external input signal. When this contact opens, the driver
generates an alarm.
It is equipped with a high inertia flywheel, to permit more gradual deceleration of the tread belt in
the event of a power outage or emergency stop.
ATTENTION: dangerous voltages are present at the motor and flywheel.
The tread belt motor power see at the paragraph: 2.5. "Technical specification".

3.10. ELEVATION MOTOR

This is a linear actuator equipped with 24 Vdc motor, integral reduction gear and a rod that is
pushed backward and forward by the motor. This rod acts upon a frame connected to the front
wheels of the machine: when the rod moves so does the frame, thereby lowering raising the
machine.
The actuator has a built-in Hall effect sensor which acts as an encoder, generating pulses when the
motor moves. This furnishes a feedback signal on the motor movements, which is used for tracking
the position of the rod and hence the elevation of the machine.

3.11. LIMIT SWITCH

This is a NC microswitch which defines the zero-reference position for the elevation mechanism:
the switch is positioned so that it is pressed by the machine during the reset procedure, thereby
defining the reference position.
