How the ASSA ABLOY SW200 works

The swing door operator ASSA ABLOY SW200 uses a DC motor which is connected to the output

shaft by a combination of a bevel gear and spur gears. The arm system that is connected to the

output shaft opens the door in a wall mounted application.

There is also an adjustable spring mechanism connected to the output shaft. During opening of

the door, the clock spring is tensioned by the rotation of the output shaft. During the closing cycle,

the accumulated spring force is acting in the closing direction. The spring force can be adjusted so

there is appropriate force to close the door when it is operated manually or in case of a power

failure.

5.1

When an activation signal is received by the control unit, the door is opened at the installer-adjusted

opening speed. Before the door is fully open at back check, it slows automatically to low speed.

The motor stops when the selected door opening angle has been reached. The open position is

held by the motor.

If the door is obstructed while opening, it will either stall or stop which can be selected with a DIP-

switch (SOS). Stop on stall is always active in program selector Mode Off.

• Continue on stall - the door will continue to try to open during the hold open time.

• Stop on stall - the door will, even if hold open time has not expired, close after 2 seconds.

5.2

When the hold open time has elapsed, the operator will close the door automatically, using spring

force and motor. The door will slow to low speed at latch check before it reaches the fully closed

position. The door is kept closed by spring power or combined with extended closing torque by

the motor.
