INSTALLING THE OPERATOR


Horizontality of the operator
O
The operator must work horizontally: to do
this, the supports must be positioned with a
height difference of 19 mm.

Assembly positions and dimensions

For the correct operation of the operator, it is
essential that the supports are positioned respecting
the dimensions calculated, with regards to the gate
and its rotation axis.
O
IT IS VERY IMPORTANT TO RESPECT THE
DIMENSIONS: If the dimensions are not
respected exactly, the piston rod will not make
the whole travel, meaning the mechanical slow
down system will not work.

The dimensions are selected using either the table or
the attached chart. The table indicates some specific
cases, whilst the chart shows all the possible cases.
The assembly dimensions depend on the opening angle
of the gate and the following factors:
• Type of operator chosen: short (Piston rod travel =
265mm) or long (Piston rod travel = 400mm)
• Opening of the gate inward or outward.
Hence there are four different cases, as explained below
(each case is represented by way of its corresponding
diagram, table and chart).
