Safety
Information for the user
In all applications involving the use of machine tools or
CMMs, eye protection is recommended.
Remove power before performing any maintenance
operations.
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 machine movement.
The expected method of providing an emergency stop for
Renishaw products is to remove power.
Information for the machine supplier/installer
The automatic probe cover (APC) 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 or HSI-C
disconnected.

安全须知
用户须知
在所有涉及使用机床或坐标测量机 (CMM) 的应用中，建
议采取保护眼睛的措施。
在执行任何维护作业之前，请先断开电源。
机床制造商有责任确保用户了解操作中存在的任何危险
（包括雷尼绍产品文件中提到的危险），并应确保提供充
分的防护装置和安全联锁装置。
在某些情况下，有误发测头已复位状态信号的可能。切勿
单凭测头信号来停止机床运动。
紧急关闭雷尼绍产品的方法是断开电源。

Warnings
The following residual risks of this device need to be
managed to an acceptable level by the integrator:
• Sound pressure level: this device emits noise as
an essential part of its operation and has been
measured at 76dB(A).
• Pinch point: when this device operates there is a
pinching hazard between the stylus cube and the
cover
• Care must be taken when installing or cleaning the
product inside the machine tool to ensure sharp
objects are avoided.
• Ejection of debris: when “air bleed” is activated
debris (including metal particles) can be ejected from
the cover
• Installation of this pneumatically powered device
presents foreseeable pneumatic and mechanical
hazards so should only be installed by a competent
person.
• The sound pressure level, pinch point and “air bleed”
hazards identified above will need to be managed
during maintenance of the machine or this device.

机床供应商/安装商须知
自动测针保护罩 (APC) 系统必须由有资质的人员在遵守
相关安全措施的前提下进行安装。在开始工作之前，须确
保机床电源关闭，处于安全状态，并且HSI或HSI-C的电
源已断开。
警告
集成商必须将该设备的以下残余风险控制在可接受范围
内：
••声压级：该设备运行时的一个基本特点是发出噪声，
噪声值为76 dB(A)。
••注意卷夹：当设备运行时，在方形测针和保护罩之间
存在夹伤危险。
••在机床内安装或清洁该产品时，必须谨慎操作以确保
避开尖锐物体。
••碎屑弹出：当吹气系统启动时，可能会有碎屑（包括
金属颗粒）从保护罩内弹出。
••该气动设备的安装操作存在可预见的气动和机械危
险，因此必须由有资质的人员进行安装。
••对机床或该设备进行维护时，必须对上述声压级、卷
夹和吹气系统可能存在的危险进行管控。

Introduction
The automatic probe cover (APC) is a tool setting
probe that features a pneumatically-operated
protection cover for lathes and multi-tasking
machines. The APC is designed to protect
the stylus when it is mounted in a hazardous
environment on a machine tool.
The APC is typically used when the probe is
mounted in a harsh environment; for example,
where exposed to large pieces of ying swarf, or
long strands of swarf wrapping around the stylus
that can damage the probe when pulled away.
The pneumatically-operated cover will protect
the probe’s stylus and allow it to operate in this
hazardous environment.

APC probe family
The APC family of tool setting probes currently
consists of:
•APCA air extension and air retraction
•APCS air extension and spring retraction
The term APC used throughout this installation
and user’s guide refers to both versions.
Features
The APC features an “air bleed” function. “Air
bleed” is where air ows through the APC
mechanism at a constant rate over the stylus cube
when the APC cover is extended or retracted to
help prevent build up of contamination on the
stylus cube.
The APC also features an air blast port.
The customer can supply, t and control an air
blast pipe to suit their requirements. For example
this could be used for cleaning the stylus or
cutting tool before measuring.
NOTE: A retract conrm sensor provides the
machine controller with a signal to indicate that
the APC cover is retracted.

Interface unit
HSI interface unit HSI-C interface unit
Introduction
An HSI or HSI-C interface unit is required to
convert the signals from the APC unit into
voltage-free solid-state relay (SSR) outputs for
transmission to the CNC machine controller, which
responds to the probe inputs.
WARNING: Before installing the interface unit,
ensure that the machine is safe to work on. Switch
off machine power when working in the control
cabinet.
In addition to the features of the HSI, the HSI-C
enables the user to select a suitable level of
immunity to false triggering (caused by machine
vibrations or accelerations) for the connected
APC unit. The HSI-C can also respond to a
conguration override input that switches the
probe to the highest level of immunity to false
triggering when manoeuvring to a measure
position at high speed.

4
The interface unit should be installed in the CNC
controller cabinet. Where possible, locate the unit
away from potential sources of interference such
as transformers and motor controllers.
Installing the interface unit
Install and congure the interface unit as
described in the HSI hard-wired system
interface installation guide (Renishaw part no.
H-5500-8554), or the HSI-C hard-wired system
interface – congurable installation guide
(Renishaw part no. H-6527-8501).
