Disposal of waste electrical and
electronic equipment (WEEE)
The use of this symbol on Renishaw
products and/or accompanying
documentation indicates that the product
should not be mixed with general
household waste upon disposal. It is the
responsibility of the end user to dispose
of this product at a designated collection
point for waste electrical and electronic
equipment (WEEE) to enable reuse or
recycling. Correct disposal of this product
will help to save valuable resources and
prevent potential negative effects on
the environment. For more information,
contact your local waste disposal service
or Renishaw distributor.
Intended use
The HPGA system is a motorised
high-precision tool setting solution
predominantly intended for use on
3-axis CNC grinding machines and CNC
lathes for workpiece inspection, tool
measurement and broken tool detection.

Safety
Information to the user
In all applications involving the use of
machine tools, eye protection and safety
footwear is recommended.
Remove power before performing any
maintenance operations.
The expected method of providing an
emergency stop for Renishaw products is
to remove power.
Information to the machine supplier /
installer
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
literature, and to ensure that adequate
guards and safety interlocks are provided.
If the probe system fails, the probe signal
may falsely indicate a probe seated
condition. Do not rely on probe signals to
halt the movement of the machine.
The high-precision generic arm (HPGA)
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 TSI 3, TSI 3-C or HSI
disconnected.
CAUTION: HPGA and TSI 3 / TSI 3-C /
HSI are intended for exclusive use as
part of the HPGA system. Any attempts
to integrate with other arms or interfaces
could result in unexpected behaviour and/
or product damage.
Information to the equipment installer
All Renishaw equipment is designed to
comply with the relevant UK, 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 specied by the manufacturer, the
protection provided by the equipment may
be impaired.

安全须知
用户须知
在所有涉及使用机床的应用中，建议
采取保护眼睛的措施，并应穿着安全靴。
在执行任何维护操作之前，请先断开
电源。
雷尼绍产品的建议急停方法是断开电
源。
机床供应商/安装商须知
机床制造商有责任确保用户了解操作
过程中存在的任何危险，包括雷尼绍产品
说明书中所述的危险，并应确保提供充分
的防护装置和安全联动装置。
如果测头系统发生故障，则可能误发
测头已复位的信号。切勿单凭测头信号即
停止机床运动。
高精度通用对刀臂 (HPGA) 系统必须
由具备资质的人员在遵守相关安全措施的
前提下进行安装。在开始工作之前，须确
保机床的电源已关闭，处于安全状态，并
且TSI 3、TSI 3-C或HSI的电源已断开。
小心：HPGA和TSI 3 / TSI 3-C / HSI仅可作
为HPGA系统的一部分进行使用，如果试图
将其与其他对刀臂或接口进行集成，将可能
导致意外操作及/或产品损坏。
设备安装商须知
雷尼绍所有设备的设计均符合相关的
UK、EU和FCC监管要求。为使产品按照这
些法规正常运行，设备安装商有责任确保
遵守以下指导原则：
• 任何接口的安装位置必须远离任何潜
在的电噪声源（例如变压器、伺服系
统驱动装置）。
• 所有0伏/接地连接都应当连接到机床接
地终端上（“接地终端”是所有设备
地线和屏蔽电缆的单点回路）。这一
点非常重要，不遵守此规定会导致接
地点之间存在电位差。
• 所有屏蔽装置都必须按照使用说明书
中所述进行连接。
• 电缆线路不得与电机电源电缆等高电
流源并行或靠近高速数据传输线。
• 电缆长度应始终保持最短。
设备操作
如果设备的使用方式与制造商要求的
方式不符，则设备提供的保护功能可能会
减弱。
