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.
Check horizontality using a Spirit level.
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.
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).
