Safety
Information to the user
In all applications involving the use of machine tools or CMMs, eye
protection is recommended.
Information for the machine supplier/installer
It is the machine supplier’s responsibility to ensure that the user is
made aware of any hazards involved during operation, including
those mentioned in Renishaw product literature, and to ensure that
adequate guards and safety interlocks are provided.
Under certain circumstances, the probe signal may falsely
indicate beam not blocked. Do not rely on probe signals to halt the
movement of the machine.
Information to the equipment installer
All Renishaw equipment is designed to comply with the relevant
EU and FCC regulatory requirements. It is the responsibility of
the equipment installer to ensure that the following guidelines are
adhered to, in order for the product to function in accordance with
these regulations:
• any interface MUST be installed in a position away from any
potential sources of electrical noise (for example, power
transformers, servo drives);
• all 0 V/ground connections should be connected to the machine
“star point” (the “star point” is a single point return for all
equipment ground and screen cables). This is very important
and failure to adhere to this can cause a potential difference
between grounds;
• all screens must be connected as outlined in the user
instructions;
• cables must not be routed alongside high current sources (for
example, motor power supply cables),or be near high-speed
data lines;
• cable lengths should always be kept to a minimum.
Equipment operation
If this equipment is used in a manner not specied by the
manufacturer, the protection provided by the equipment may be
impaired.
Warnings
Use of controls or adjustments or performance of procedures other
than those specied within this publication may result in hazardous
radiation exposure.
Switch off the power supply before carrying out maintenance on
the NC4 system.
When using the NC4 system, basic safety precautions must
always be followed to reduce the risk of re, electric shock and
personal injury, including the following:
• Read all instructions before operating this product.
• The device must only be installed and used by competent,
trained personnel.
• Use eye protection to protect against mechanical hazards,
coolant and swarf.
• Avoid inhalation of coolant vapour from the machine tool.
• Do not block the air exiting from the transmitter, receiver or air
blast apertures.
• The sound power emitted by the air blast equipment can
range from 70.3 dB at 3.0 bar (43.51 psi) to 78.2dB at 6.0 bar
(87.02psi). It is the responsibility of the integrator to ensure a
suitable noise assessment is performed when the equipment
is put into use.
• Prevent direct exposure of the eyes to the laser beam.
Ensure that the beam is not reected into the eyes via any
reective surface.
