Thermal---magnetic circuit breaker
: this device incorporates two power fail-
ure protection systems. In fact, in the event of a power failure, it disconnects
all the electrical components, causing the machine to shut down immediately
and prevents it from automatically starting up again when power is restored.
The device also resets the thermal relay fitted to protect against current over-
loads.
3.
Head casing safety switch
: to access the cutting zone it is necessary to open
the front door, pressing the relevant button on the control console. This de-
vice cannot be removed and has timed opening; therefore, it can only be
opened 5 or 10 seconds after the processing cycle has stopped.
4.
Feeder casing safety switch
: to access the cutting material feeder, it is necess-
ary to open the casing, with a safety limit switch that stops all machine oper-
ations that must be reset to continue processing.

Noise level of the machine
Noise can cause hearing damage and represents one the problems faced by many
countries who adopt their own standards. In accordance with the
EEC MA-
CHINES DIRECTIVE 2006/42/CE
, we are listing the standards that specify noise
levels for machine tools. This chapter also reports the noise levels produced by
the
TIGER 370 CNC---MR
during its various operating phases and the methods
used for measuring these levels. The Italian standard governing this aspect is
D.M.n.277/91 drawn from EEC Directives 80/1107, 82/605, 83/477, 86/188, 88/642,
UNI EN ISO 4871 (1998).
Noise level measurement
Noise levels are measured using an instrument known as an Integrator noise---
meter which registers the equivalent continuous acoustic pressure level at the
work station. The damage caused by noise depends on three parameters: level,
frequency and duration. The equivalent level concept Leq combines the three
parameters and supplies just one indication. The Leq is based on the principle of
equal energy, and represents the continuous stationary level containing the same
amount of energy, expressed in dBA, as that actually fluctuating over the same
period of time. This calculation is made automatically by the integrator noise---
meter. The measurements are taken every 60 seconds, in order to obtain a
stabilised value. The reading stays on the display for a sufficient time to enable a
reading to be taken by the operator.Measurements are taken by holding the
instrument at approximately 1 metre from the machine at a height of 1.60 metres
above the platform at the operator’s work station. Two measurements are taken:
the first while the machine operates without cutting anything, the second while
cutting in manual mode.
