6. Design and Function Description
6.1 Design
The sliding door operator ASSA ABLOY SL300 works electromechanically. The system components including the motor, control unit, transmission, optional battery, and electromechanical locking device are all assembled in a support beam.
The motor and gear box transmit movement to the door leaves by means of a tooth belt. The door leaf is fitted to a door adapter/carriage wheel fitting and hangs on a sliding track. Movement of the bottom of the door leaf is controlled by the floor guides.
6.2 Function
Opening
When an OPENING IMPULSE is received by the control unit, the motor starts and transmits movement to the door leaves, which move to the open position.
Closing
The closing starts when no OPENING IMPULSE is received and the HOLD OPEN TIME has run out.
6.3 Safety Functions Integrated in the Operator
To permit safe passage between closing doors, the doors immediately reverse if an obstruction is detected, then resume their interrupted movement at low speed to check whether the obstruction has disappeared or not.
If an obstruction is detected while the door is opening, the doors immediately stop and then close after a time delay.
6.4 Microprocessor for Precise Control
The microprocessor has a routine for self-monitoring, which detects any interference or faulty signals in door operation. If an input signal does not correspond to the preprogramming, the microprocessor automatically takes necessary actions to ensure safe door operation.
6.5 Power Failure
The ASSA ABLOY SL300 can be equipped with a battery unit that automatically opens the doors in the event of a power failure. The operator is not allowed to be used in an escape route.
