Description and operation
The open/close control is only activated with the vehicle moving, via the instrument panel push button.
If the vehicle is provided with a centralized closing system, door opening can be activated even with the vehicle stationary. In
this case, opening and closing must be limited to prevent discharging the vehicle battery.
Opening with the instrument panel push button
The operator controls automatic door opening by actuating the instrument panel push button.
Pressing the push button sends an electrical impulse required for mechanical electro magnetic induced lock release.
At release end, the lock on travel end warning loses the signal and starts the motor reduction gear that makes the door panel
rotate open and given visual warning of door open, with a warning light on the instrument panel.
Opening end is with the Complete Opening micro switch.
During door opening, a cam located on the lower part of the hinge and solidal with motor reduction gear rotation lowers the
access step to its use position.
Closing with the instrument panel push button
The operator controls automatic door closing by actuating the instrument panel push button.
Pressing the push button sends an electrical impulse to the motor reduction gear that completes its closing travel.
During closing a double obstacle detection system operating on motor ammeter measurement and adjustable via a timer on the
center is activated, another one is located on the compressed air sensitive edge of the two door compartment uprights.
Near door close a position reading sent to the tachometer on the door control motor disenables the ammeter controlled
sensitive edge to enable otherwise impossible door closing.
The compressed air sensitive edge is activated until receipt of door closed micro switch signal, which activates a signal switching
all center functions off.
When closing, the door enables rotation of the mobile step to its rest position with a return spring.
If the vehicle moves with the door open, its closing can be controlled with the push button even at speeds over 5 Km/h, in which
case the buzzer remains active (inclusive of the door open warning light) until complete door closing.
Opening/closing with the remote control
The open/close control extends to all vehicle doors including the rotating sliding one.
Movement inversion
After door open/close push button actuation, in whatever position it may be, actuating the push button generates its controlled
movement inversion.
Obstacle detection system
The system features motor ammeter control capable of detecting peaks of voltage and of the compressed air sensitive edge
located on the front and back of the door compartment, for obstacle detection.
If an obstacle counters door panel movement during closing, over 150N force of compressed air transducer activation opens it.
If an obstacle counters door panel movement during opening, over 150N force of compressed air transducer activation closes it.
Since the door is equipped with the anti-squash function, reading the nearly closed door status signal generated by the motor
encoder automatically cats out this function to enable complete door closing.

The door can be opened in case of system failure or power
down by using the emergency lever from the inside of the lock
close to the door panel from the outside.
In case of emergency operation, automatic door opening or
closing is disenabled until the system is restarted manually.
The outside emergency lock is provided with a key that can
be used to secure the vehicle (Figure 325).
An internal buzzer is actuated if the starter switch is actuated
in the service position with external opening emergency
locked with the key.
Diagnosis
The system reports a failure when the failure warning light
goes on.
This failure can be due to the following causes:
- Closing does not occur a maximum of ~20 sec after
actuation
- Possible causes:
Door open micro switch warning failed.
Electrical cabling cut.
- Over voltage when opening or closing
- Possible causes:
Motor short circuit
- Door opening/closing travel abnormal.
- Possible causes:
Motor encoder signals not recognized.
- Door does not open.
- Possible causes:
Tachometer signal detective or down.
