FCC
Information to users (FCC section 15.105)
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated
in a commercial environment. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case
you will be required to correct the interference at your own expense.
Information to the user (FCC section 15.21)
The user is cautioned that any changes or modifications not expressly approved by
Renishaw plc or authorised representative could void the user’s authority to operate the
equipment.
Special accessories (FCC section 15.27)
The user is also cautioned that any peripheral device installed with this equipment
such as a computer, must be connected with a high-quality shielded cable to insure
compliance with FCC limits.
TÜV
This equipment has been independently certified by TÜV Product Services in
accordance with OSHA (US) and SCC (Canada) requirements to the standards
UL61010-1 Second Edition and CAN/CSA-C22-2 No. 61010-1 Second Edition.

Safety
Electrical requirement
If this product is not used in its intended manner, any protection provided may be
impaired.
The PI 4-2 is powered from the a.c. mains supply via an IEC 320 connector. The
electrical ratings of the unit are as follows:
100-240 V ac +10%, -15% 47 - 66 Hz 10 W
This equipment must be connected to a protective earth conductor via a three core
mains (line) cable. The mains plug shall be inserted only into a socket outlet provided
with a protective earth contact. The protective earth contact shall not be negated by the
use of an extension cable without protective conductor.
WARNING: Any interruption of the protective conductor may make the
equipment dangerous. Make sure that the grounding requirements are strictly
observed.
Environmental requirements
The following environmental conditions comply with (or exceed) BS EN 61010-1:1993:
Indoor use only
IP30 (no protection against water)
Altitude
Up to 2000 m
Operating temperature
0 °C to +50 °C
Storage temperature
-10 °C to +70 °C
Relative humidity
80% maximum for temperatures up to +31 °C
Linear decreases to 50% at +40 °C
Transient voltages
Installation category II
Pollution degree
2
The PI 4-2 is isolated from AC power by disconnection of the IEC mains connector on
the rear panel. If any additional means of isolation is required, it must be specified and
fitted by the machine manufacturer or the installer of the product. The isolator must
be sited within easy reach of the CMM operator and comply with IEC61010 and any
applicable national wiring regulations for the country of installation.

Care of equipment
Renishaw probes and associated systems are precision tools used for obtaining precise
measurements and must therefore be treated with care.
Changes to Renishaw products
Renishaw plc reserves the right to improve, change or modify its hardware or software
without incurring any obligations to make changes to Renishaw equipment previously
sold.
Warranty
Renishaw plc warrants its equipment provided that it is installed exactly as defined in
associated Renishaw documentation.
Consent must be obtained from Renishaw if non-Renishaw equipment (e.g. interfaces
and/or cabling) is used or substituted. Failure to comply with this will invalidate the
Renishaw warranty.
Claims under warranty must be made from authorised services centres only, which may
be advised by the supplier or distributor.

Introduction and general description
1 Introduction and general description
The function of a probe interface is to manage the probe to ensure that it produces
repeatable and reliable results over a long service life. This is achieved by careful
control of the probe current, trigger threshold and signal conditioning. A probe interface
also controls the head PROBE STATUS LED and provides clean output signals.
The PI 4-2 is a basic probe interface for use with Renishaw’s conventional touch-trigger
probes (TP1, TP20, TP6, MH20i etc.). It is suitable for use on both manual and direct
computer control (DCC) co-ordinate measuring machines (CMMs).
The PI 4-2 has been introduced as a replacement for the PI 4, PI 9 and PI 12 interfaces
and conforms to the relevant CE directives in force at the time of issue. It is housed
in the modern Renishaw enclosure compatible with the latest PHC10-2 and other
controller/interfaces.
The PI 4-2 interface has both solid state relay (SSR) and Renishaw product interconnection system (PICS) output options. It will also support the remote inhibit hand
control unit (HC-2).
