SAFETY
Information for the User
For instructions regarding the safe cleaning of
Renishaw products, refer to the MAINTENANCE
section of the relevant product documentation.
Replace blown fuses with new components of
the same type. Refer to the SAFETY section of
the relevant product documentation.
Remove power before performing any maintenance
operations.
Refer to the machine supplier's operating
instructions.
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 machine
movement.
FCC DECLARATION (USA)
FCC 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 harmfull interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation.
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.
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.
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.

MI 5 INTERFACE UNIT
CNC machine tools using a Renishaw probe system for tool setting or workpiece set-up and inspection
require an interface unit, to convert probe signals into an acceptable form for the CNC machine control.
The MI 5 interface unit is part of probe systems using hard wired or inductive signal transmission.

MI 5 FUNCTION
SAFETY
Remote Audible Indicator or LED
If the MI 5 is installed where it not be easily seen,
outputs are provided for a remote audible indicator
or LED, to be positioned near the machine operator
(see wiring diagram page 1-4).
Audible Indicator
A tone is emitted each time the probe
changes state.
(From stylus at rest to stylus deflected
or stylus deflected to stylus at rest).
Probe Status LED
(Light Emitting Diode)
Lit when probe is at rest or interface is inhibited.
Unlit indicates probe stylus is deflected or power is off.
Only qualified persons should adjust
switches or replace fuses.
Remove mains supply from units
before removing covers.
1-2
The MI 5 interface processes signals from Renishaw
probes and converts the signals into voltage free
Solid State Relay (SSR) output, for transmission to
the CNC machine control, which stores work offsets
and responds to probe inputs.
The probe status LED is lit when the probe stylus
is seated (at rest), or the interface is inhibited.
When the probe stylus deflects on making contact
with a surface, a signal is generated causing the
MI 5 output relays to change state, the LED to
switches off and the audible indicator emits a 'bleep'.
As the probe moves clear of the contact surface,
the audible indicator emits a second 'bleep', and
the LED lights up, indicating that the probe stylus
has reseated, and the probe is available for the next
contact in the probing routine.

MI 5 INSTALLATION
Power Supply
The MI 5 can draw its power from the CNC
machine 24V nominal DC supply. Its input voltage
range is 18V DC to 30V DC and it presents load of
up to 200mA. Alternatively it can be powered from
a Renishaw PSU3 Power Supply Unit.
Note : Incorrect polarity of the DC supply
will blow fuse FS1.
Inhibit/Enable Function - two probes
When the machine has two probes, the CNC
control must be able to identify which probe
is in use. e.g. Hard wired tool setting probe or
inspection probe with inductive transmission.
The MI 5 has inputs for two probes. To enable
both systems to be used safely, the MI 5 also
contains a pair of remote inhibit inputs, which
allows the control to select the probe to be used.
Single Hard Wired Tool Setting Probe Operation
See probe input linking on terminals 18 and 19 (page 1-4).
Single Inductive Inspection Probe Operation
See probe input linking on terminals 21 and 22 (page 1-4).
Simultaneous - two probes
Tool Setting and Inspection Probe Operation
When one probe is inhibited it is held in a 'probe at rest'
state so that the other probe output will not be masked.
This can be automatically controlled by an M code
(miscellaneous function) from the CNC machine control.
To activate the inhibit function, a voltage of 18 to 30V
DC should be applied across the input terminals
(ensure correct polarity). The inhibit function consumes
a nominal 7mA when activated.
Take care to avoid potential sources of interference, such as three phase transformers and motor controllers.

TO ENSURE OPERATOR SAFETY
It is recommended that a fail safe
SPINDLE ROTATION INHIBIT
is built into the machine
installation.
The example shows the probe
cable plugged into the probe
socket, preventing spindle
rotation.
When the probe cable (dotted
lines) is plugged into the remote
socket, spindle rotation is
enabled.

LP2 HARD WIRED INSPECTION SYSTEM
SAFETY
The probe should not be rotated (spun) by the machine spindle with the cable connected. If this
is allowed, then serious injury could occur to persons nearby due to flying cable or entanglement.

OUTPUT SIGNAL
The output signal from the interface
must be compatible with machine
control.
The two output devices are identical
and have the following specification:
Solid State Relay (SSR)
Normally Closed (N/C).
or
Normally Open (N/O).
(Teledyne 640-1 or equivalent).
Maximum current ±40mA peak.
Maximum voltage ±50V peak.
SSR OUTPUT A
Can be configured for
Probe Status N/O or Probe Status N/C.
(see Wiring diagram page 1-4).
SSR OUTPUT B
Can be configured for either
Skip N/O or Skip N/C.
or
Probe Status N/O or Probe Status N/C.
(see Wiring diagram page 1-4).
OCT and TTL style outputs can
be emulated using the SSR's.
OCT and TTL circuits are shown
on page 1-6.

Note: Change of state debounce time is 17,5mS ±5,5mS.
Skip pulse length is 32,5mS ±12,5mS.
Debounce time is the time delay after the MI 5
has responded to probe a trigger, before it can
be used again.
