Voltage must arrive upstream from the
fuses (terminal board).
Checkelectricalefciencyandcheckfor
shorts that trigger such protections.
Check closing of the flywheel guard.
Checktheefciencyofthedevice;replace
it if damaged.
It must be turned to position 1 or 2.
Ensure that it is off and that its contacts
are unbroken.
Check mechanical efciency; replace if
damaged.
Check that thermal relay protecting band
motor is correctly cennected.
Check that the supply voltage is the same
as the line voltage and that it gives a value
of 24 V at output.
Check fuse efciency and ensure there
are no short circuits causing the protection
to trip.
Checkoperationand/orefciency;replace
if broken.
Check that phases are present at both
input and output; ensure that it is not
blocked, that it closes when fed, that it
doesnotcauseshortcircuits;otherwise
change it.
Check that it is not burnt and that it turns
freely.
It may be rewound or changed.

NOISE TESTS
In accordance with point 1.7.4.f of the Machines Directive EEC 98/37
2 measurements with the machine operating unloaded.
- The microphone was been located close to the operator's head, at medium height.
- The weighted equivalent continuous acoustic pressure level was 68,1 dB (A).
- The maximum level of the WEIGHTED instantaneous acoustic pressure C was always less than 130 dB.
NOTE: with the machine operating, the noise level will vary according to the different materials being processed. The user must there-
fore assess the intensity and if necessary provide the operators with the necessary personal protection, as required by Law 277/1991.
