Safety
Information for the user
In all applications involving the use of machine
tools or CMMs, eye protection is recommended.
Refer to the machine supplier’s operating
instructions.
The LP2 system must be installed by a
competent person, observing relevant safety
precautions. Before starting work, ensure that the
machine tool is in a safe condition with the power
switched OFF and the power supply to the HSI/
MI 8-4 is disconnected.
Information for the machine supplier
It is the machine supplier’s responsibility to
ensure that the user is made aware of any
hazards involved in operation, including those
mentioned in Renishaw product documentation,
and to ensure that adequate guards and safety
interlocks are provided.
Under certain circumstances the probe signal
may falsely indicate a probe seated condition.
Do not rely on probe signals to stop a machine’s
movement.

1-6 Introduction
Introduction
The LP2 is a compact and versatile probe for
applications on CNC lathes and machining
centres. A wide range of styli and accessories is
available to provide custom installations.
Principal applications
Horizontal lathes
Small enough to fit on a turret for part measuring,
tool setting and broken tool detection when
mounted in a suitable position.
Machining centre applications
Set-up and part measuring when spindle
mounted. Tool setting and broken tool detection
when table mounted.
Signal transmission systems
• Hard-wired – a range of hard-wired probe
sockets is available for inspection and tool
setting applications. For machining centres
with manual tool change the LP2 will fit the
MA2 probe holder.
• Optical or radio – for lathes and machining
centres. Easy installation, particularly in
retrofit applications because there is no
need for the prepared passageways required
for hard-wired transmission cables. LP2
can be used with OMP40M, OMP60M,
RMP40M, RMP60M.
Interface Unit
A hard-wired installation with LP2 may use the
HSI interface, see the HSI interface installation
guide (Renishaw part no. H-5500-8554), or the
MI 8-4 interface, see the MI 8-4 Installation and
user’s guide (Renishaw part no. H-2000-5008).
The FS1i and FS2i probe sockets with integral
interface may also be used, see the FS1i and
FS2i probe sockets data sheet (Renishaw part
no. H-2000-2073).
