OSITIONING OF THE FRONT FIXATION
Depending on the type of the gate (wood, iron, aluminium) the front
fixation can be welded or screwed (Fig. 6).
Mount the front fixation so that it guarantees the perfectly
horizontal position of the operator (Fig. 7).
N.B.: Ensure that when the door is fully open and fully closed the
rod is not at the end of its stroke, but is at least 15mm from
the end of its stroke on each side.
Fix the IDRO and try several times to open and to close the gate,
controlling that the cover does not touch the moving gate, otherwise
you have to readjust the ancorage on the gate.
In the case you have a wall parallel with the open gate, you must
provide a niche in which to place the operator.

LECTRICAL SAFETY DEVICES
In addition to compliance to all mechanical safety regulations, gates
with leaf length exceeding 1.8 m must be fitted with two pairs of
photocells capable of interrupting gate movement.
The photocells must be installed at a height of 40 - 60 cm between the
gate posts on the outside of the structure.
The other two photocells must be installed at the same height as the
previous ones on the ends of the gate leafs to form a barrier between
the leafs when open.
Gate movement must be indicated by a flashing unit placed near the
gate.
Use the T2 (for one or two single-phase motors) electronic control unit.
For connections and technical data of accessories refer to the
appropriate booklets.
