Assembly Of The Emergency Release Lever - DITEC Flash C Manual De Instalación, Manutención Y Utilización

3.7 Assembly of the emergency release lever

The emergency release lever must either be
assembled on the structure itself (using the special
holes in the left column) or on the wall, at an easily
accessible height (Fig. 13).
In the case of assembly on the structure in a different
position, use the measurements indicated in Fig. 14
and position the activation cable in the interspaces
shown in Fig. 13, connecting it to the motor brake (Fig.
15).
Check that the device functions correctly; when the
lever is activated the curtain should be free to rise.
Place the microswitch FS in position, checking that it is
pressed against the release lever (Fig.16).
3.7.1 Adjustment of the counterbalancing
Use the 4 cast-iron elements removed earlier to
achieve optimal calibration in such a way that the
curtain is able to move freely when the release lever is
activated, but without violently hitting the mechanical
end-of-stroke device at the top.
