FCC Information to user (USA only)
47 CFR Section 15.19
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, including interference that may cause
undesired operation.
47 CFR 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.
47 CFR 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
the user will be required to correct the interference at his own expense.

Safety
Information to the user
In all applications involving the use of machine tools or CMMs, eye protection is recommended.
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 fails, the probe signal may falsely indicate a probe seated condition. 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Vdc/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 specified by the manufacturer, the protection provided by the
equipment may be impaired.

2.1
Introduction
HSI-C is an interface unit that is intended for use with the RENGAGE™ MP250 and standard probes
used on CNC machine tools and cutter grinding machines. The interface unit is required to convert the
signals from the probe into voltage-free solid-state relay (SSR) outputs for transmission to the CNC
machine controller. The maximum SSR output operating current is 50 mA.
Typically installed within the CNC machine controller cabinet, and located away from sources
of interference such as transformers and motor controls, the HSI-C can draw its power from the
machine’s nominal +12 Vdc to +30 Vdc supply. Where such a supply is not available, the HSI-C can be
powered using any +12 Vdc to +30 Vdc (minimum 0.5 A) power supply. The machine’s supply should
be appropriately current limited to 10 A maximum.
The supply is protected by a 140 mA self-resetting fuse (its nominal current, when connected to an
inspection probe, is either 40 mA@12 Vdc or 23mA@24 Vdc). To reset the fuse, remove the power
then identify and rectify the cause of the fault.
The HSI-C enables the user to select a suitable level of immunity to false triggering for the connected
probe, caused by machine vibrations or accelerations. The HSI-C can also respond to a config
override input that switches the probe to the highest level of immunity to false triggering when either
manoeuvring to a measure position at high speed, or when measuring with ‘heavy’ styli at high speed.
