How the Besam SW300/SW150 works

The swing door operator Besam SW300/SW150 uses a DC motor and a gear-reduction system to
drive an arm system which opens the door. Closing power is provided by a motor and a closing spring
(not for Besam SW150). A highly sophisticated electronic control unit uses a motor encoder and a
microprocessor to control the door's movement.
To activate the operator you can use a manual activator (elbow switch) or an automatic activator
(radar device). It is also possible – where local standards allow – to activate the operator by just
pushing the door, if Push & Go is selected.
After the door has been activated it will open and stay open for a specified Hold Open Time (HOT).
When the HOT has elapsed the door will close.
The Besam SW300/SW150 can be set in three or four different modes, depending on programme
selector type, see table below.
In fully manual use (or in case of a power failure) the Besam SW300 acts as a normal door closer.
The Besam SW150 has no spring and if open at power failure, door will not close.
