6. COMMISSIONING
WARNING
The fan must not be used without first reading and understanding the
user manual and becoming completely familiar with the controls.
6.1 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
5.3.
6.2 Instructions for 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.
WARNING
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.
