7. COMMISSIONING
The fan must not be used without first reading
and understanding the user manual and
becoming completely familiar with the controls.
Storage. All the components and spare parts
MUST be stored in dry and clean environment.
Cleaning the fan. We recommend to avoid to
use water for washing fans since the electric
motors and the bearings of the central hub and
centrifugal system support might get damaged by water
infiltration. In case there is an unbreakable need to use
water for cleaning the fans, the electric motor, the central
hub and the centrifugal weight mechanism have to be
adequately protected by water sprays.
If ununusual oscillating movement is observed,
immediately stop using the celling fan and
contact the manufacturer, its service agent or
suitably qualified persons.
Make sure the fan is disconnected from the
mains before removing the safety devices.
7.1 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.
At the fitting stage, the installer must set up a control panel
complying with the requirements of standard IEC EN 60439-
1 and arrange the wiring of the fan in accordance with the
instructions in standards IEC EN 60204-1 and IEC 60364.
The electrical circuit of the fan must generally be fitted with
the devices indicated in section 'Connection to the
electrical system'.
7.2 Instructions for machine use
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
instantaneous interruption of the power supply to the
electric motor which makes the rotor turn (uncontrolled
shutdown category 0 according to IEC EN 60204-1).
Resetting after stopping
Resetting after normal stopping
After normal stopping the operating cycle must be reset by
following the procedure described in section 'Control
devices'.
Resetting after emergency stop
After an emergency stop, the operating cycle must be reset
by following the procedure described below:
•
reset the actuator by which the emergency stop
command was given (by turning the relative mushroom
button);
•
for an exact reset sequence, refer to the instructions
given in in section 'Control devices'.
