Target group

For better readability only the masculine form of pronouns is used in these documents. Nev-
ertheless, these instructions also apply for feminine specialists.
These instructions are intended for the qualified and authorized fitter, start-up engineer and
operator of the automatic door.
Before installing and commissioning a swing door operator, read the manuals and in particu-
lar all safety instructions.
1.2.3

Storage of the manual

After the installation of the system, the instructions should be stored in an accessible and dry
place.

Description of the equipment

The record DFA 127 (Full Power) is a compact, self-monitoring, microprocessor-controlled
swing door operator (abbreviated to DFA). With its many special and additional functions, it
is suitable for a very wide application spectrum. The path of every door movement is con-
trolled 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 Norm EN 1154). Safety is also additionally increased by the use of
a redundant force limitation.
1.3.1

Low energy drive (Low Energy)

In the parameterisation of the Low Energy door type, the DFA acts as an automatic low en-
ergy operator. The opening and closing speeds are limited and the operator is more sensi-
tive in case of a collision. The closing action takes place using spring force and reduced ki-
netic energy. To prevent unintentional or malicious modifications to the program, user ac-
cess to the parameters is blocked.
The set values for the permitted speeds are indicated in EN 16005. They are calculated de-
pending on the weight of the door leaf and the width of the door.
1.4

Types of arms, including accessories

The power transmission from the motorisation unit to the door leaf is carried out by a set of
arms. Depending on the installation situation, the optimal solution can be selected from two
different types of arms (standard or slide arm). Standard arms are available in different
lengths for various lintel depths. By using optional extension pieces, so-called adaptors, dif-
ferent lintel heights can be compensated.
