D00619EN - v0 SWING OPERATOR - INSTALLATION MANUAL
5.6 Spring Adjustment
The strength of the spring should be adjusted according to the leaf width, and taking into account standard EN 1154 within
the range EN 4 to EN 6.
The adjustment range can be seen in the graph curve in Fig. 18, depending on the weight and width of the swing leaf,
and regardless of the type of arm installed. When adjusting the spring, take into account loads due to wind, excessive
pressure and other environmental conditions that tend to open a door on their own. Adjust the strength of the spring
tightening the screw (Fig. 8, Part A) such that it tenses the spring until the plate ends (Fig. 8 part B) are in the category
corresponding to the installation type (identified EN class).
Fig. 18.
WARNING: Taking into account that the spring is a component that accumulates a great deal of energy when fully
compressed, it is imperative to replace the spring and all components that operate with it exclusively with ORIGINAL
spare parts. It is convenient that a qualified technician performs scheduled maintenance tasks. For maintenance
information, refer to chapter 8 of this manual.
5.7 Selecting Breaking Level without Power
Adjust the breaking level such that it suits the closing speed and dimensions/weight of the leaf (Fig. 16). Check operation by
opening the door manually and closing it with the spring when there is no power.
Fig. 19.
5.8 Testing Operations
Before making the electrical connection, clean any traces of dust or debris and test the following items:
•
The operator is correctly mounted on the wall.
•
All the screws are tight.
•
Check the wiring and ensure there are no wires near moving parts.
•
The arm is correctly attached to the leaf.
•
The heads are correctly placed and fixed at the base.
