The fan must not be used without first
reading and understanding the user manual
and becoming completely familiar with the
controls.
4.1 conTrol DEvIcES
This chapter gives instructions on the control devices with
which the electrical control panel must be fitted, which
shall be done at the installation stage.
The electrical circuit of the fan must generally be fitted
with the devices indicated in section
‘Connection to the
electrical system’
.

Switching on and starting up
Before starting the machine:
•
check that all the guards for the hazardous areas are
in their correct positions;
•
check that all the electrical safety components are
in place and check their effectiveness by activating
them;
•
check the presence of the electricity supply.
To start the fan, go through the following procedure:
•
turn the isolator switch to position On;
•
press the fan starter button.
normal stopping
In the event of necessity the fan can be stopped by
operating the relative control device (stop), which shall
be installed on the electrical panel.
Activating this control must cause the fan blade to stop
rotating, but does not cause isolation of the power
supply: the fan can be started again by pressing the start
button.
In the event that the fan does not need to be used for an
extended period of time, the following stop procedure
must be used:
•
operate the stop button;
•
operate the emergency stop button;
•
open the main isolator switch (position ‘0’) on the
electrical panel and attach a padlock to the actuator.
Interrupting the electricity supply, equivalent
to isolating by the operator with the main
switch, causes complete fan shutdown:
restoring the electricity supply will not cause any
movement in the machine.
Emergency stop
Operating the main emergency stop button causes the
fan to stop moving.
The function is controlled by a red mushroom type button
on a yellow background, provided with mechanical
locking and release by turning.
resetting after stopping
1. Resetting after normal stopping
After normal stopping the operating cycle must be
reset by following the procedure described in section
‘Control devices
’.

!
The metal sheet used for constructing the
fan housing and shutter blades have a
minimum Z200 galvanization surface
treatment (equivalent of 14μm on each side) which
corresponds to a corrosion resistance in salty mist
of 140h. Whenever it is intended to use the fans
in ambients characterized by the presence of
particularily agressive agents (ammonia, clavolanic
acid, etc.) the user, before installing the fan at the
installation site must verify that the environmental
conditions are compatible with the intended use of
the materials that compose the fan.
!
Do not operate the fan with the safety
protections removed: safety meshes can
be removed only with specific tools by
qualified technicians when the fan reaches a
complete standstill. The fixing sytems of the safety
protections are not interchangeable with other
devices. Therefore, if for maintenance reasons the
user damages or loses any component, this must
be definetely ordered from the manufacturer as
spare parts and it cannot just be replaced with
other components, even similar, not supplied
by the constructor itself. In this particular event
the manufacturer refuses all responsibility on
consequent damages caused to things and people
and considers any kind of warranty lost.
