SAR 331 SA GDS
NOISE TESTS
In accordance with point 1.7.4.f of the Machines Directive EEC 89/392
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 66,1 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.
FAULT PROBABLE CAUSE REMEDY
12.2 - Electrical components diagnosis
Check: - phases
- cables
- socket
- plug
Voltage must arrive upstream from the fuses
(terminal board).
It must be turned to ON position.
Check electrical efficiency. Check power line
connections and relative terminals.
Check electrical efficiency and check for
shorts that trigger these protections on the
power side of the circuit.
Check closing of the flywheel guard. Check
the efficiency of the device; replace it if dam-
aged.
Make sure to have tightened the blade with
the relevant handwheel and to have actuated
the microswitch.
Ensure that it is off and that its contacts are
unbroken.
Check mechanical efficiency; replace if dam-
aged.
Check that thermal relay protecting main
motor is correctly connected.
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 efficiency and ensure there are
no short circuits causing the protection on
the control side of the circuit.
After having raised the saw frame, check
that the microswitch is not engaged and if
necessary check operating efficiency.
Check that phases are present at both in-
put 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.
