Making the correct choice of installation is essential to ensuring adequate safety and good protection against atmospheric
agents. Remember that the control unit contains powered parts and electronic components which by their very nature are
sensitive to ltrations and moisture.
The control unit is supplied in a container which guarantees an IP55 protection rating if adequately installed. Install the
control unit on a permanent surface that is perfectly
adequately protected against impacts and at least 40 cm the
ground.
The cables must enter the control unit from the bottom only; we recommend using wire leads and water-tight connections.
When using tubing that could up with water or if the tubing comes from an underground well, the wires must enter a rst
shunting box placed at the same height as the control unit and then, from there, the wires must be passed into the container
holding the control unit, again entering from the bottom.
This prevents any evaporation of the water in the tubing from forming condensation inside the control unit itself.
1.1 Preliminary checks
Remember that systems for automatic gates and doors must be installed by highly
ed technicians only and in full
compliance with current law.
Before starting installation, check that the mechanical consistency and sturdiness of the gate or door, check that the
mechanical stops are suitable to stop the movement of the gate or door even if the electrical limit switches should fail or
during manual operations.

1.3 Type of installation
These two simple diagrams show only one of the possible applications for this control unit. The risks inherent to the
“MACHINE”
and the user’s requirements must be analyzed in depth in order to establish how many elements need to be
installed. All NOLOGO photocells have a system of synchronism that makes it possible to eliminate interference between
two pairs of photocells (for other details, see the instructions for the photocells).
In the diagram, the pair of photocells
“Photo A”
(considered in this control unit) has no
during opening while it causes
a total inversion during closing.
“Photo A2”
is connected in series to
“Photo A”
.
