How the Ditec DAB305 works
The swing door operator Ditec DAB305 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. 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 Ditec DAB305 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 Ditec DAB305 acts as a normal door closer.
