3.1
Overview
These instructions are intended for the operator of the automatic swing door drive (hereinafter
referred to as DFA). By operator we mean the person responsible for the technical maintenance of
this door system.
This manual explains how to use the DFA. It forms the basis for proper function.
These instructions are to be read by the operator of the door before commissioning and the safety
instructions are to be observed!
It is recommended to keep these instructions handy near the automatic door.
3.1.1
Description of the equipment
The DFA is a compact, self-monitoring, microprocessor-controlled swing door operator. With its many
special and additional functions, it is suitable for a very wide application spectrum. The path of every
door movement is controlled by the microprocessor, which evaluates the current door position, the
door speed and the final position at every instant and precisely calculates the optimum motion. This
makes the familiar end-stops, jerky braking actions, creep speeds etc. unnecessary. Depending on
the door width, the corresponding spring range must be selected in the range of EN 4 to EN 6
(according to European standard EN 1154). Safety is also additionally increased by the use of a
redundant force limitation.
3.1.2
Low energy drive (Low Energy)
Parameterization makes it possible to use the operator as a low-energy operator.
The door is closed with reduced spring force. The opening and closing speeds can be adjusted to a
limited extent and the operator reacts more sensitively in the event of a collision. To prevent
accidental or improper changes to the programming, access to the parameters is restricted for users.
Only qualified personnel may carry out the parameterization of the operator.
The setting values for the permissible speeds are shown in EN 16005. They are calculated as a
function of the door leaf weight and door width.
