7.11 Manual operation
In the event of a power interruption, the door can be operated manually with a handle mounted
straight onto the back of the motor.
Either a semi-automatic or a fully-automatic 'operation in the event of a power interruption', can be
provided.
7.12 Control box
DYNACO doors are equipped with a control box containing a frequency inverter that controls the
motor, a magneto-thermal isolation switch (protection of the control box, inverter and motor), a
transformer supplying 24 VAC to door the accessories, an adjustable timing relay for closing and a
terminal strip for connections.
The front of the control box has a lockable main switch, a pushbutton for opening the door, and an
emergency stop button.
Standard power supply: 200 to 240 VAC., single phase; frequency: 50 – 60 Hz.
7.13 Operational safety
Because the door does not contain any rigid or semi-rigid elements, nobody will be injured through
direct contact.
DYNACO doors are equipped with:
A proximity detector: an infrared photoelectric cell, situated at approximately 20 mm from the
centreline of the door, to detect the presence of pedestrians or vehicles and if detected, to open the
door immediately and keep it open until their presence is no longer registered.
Wireless DYNACO detector: a wireless obstruction detection system comprising a transmitter and
receiver. When the sensor touches an obstacle, it sends a signal to the receiver, which immediately
opens the door.
7.14 Maintenance
Always follow the safety instructions contained in the manual before carrying
out any maintenance on the door.
To ensure that the door will always perform satisfactorily, the following points must be checked
regularly.
• The frame (distortion caused by a collision)
• Guides: distortion that may reduce the effectiveness of the retaining straps on the sides and the
effective self-fixing ability of the door.
