OLP40 basics
Introduction
Welcome to the OLP40 job set-up and inspection
probe.At only 40 mm diameter, this compact
probe sets industry standards for functionality,
reliability and robustness in the harshest of
machine tool environments.
The OLP40 is ideal for small to medium lathe and
turning centres including the growing range of
HSK machines.
• The OLP40 can use either modulated or
legacy transmission modes.
• full compatibility with Renishaw's industry
proven optical transmission systems.
• 360° optical 'switch on' facility allows probe
to be switched on and off in any position.
Optical transmission method
The OLP40 can be operated in either modulated
or legacy mode.
Modulated mode
Certain forms of light interference can cause
false triggers or mimic a start signal and falsely
activate the probe.These effects are much
reduced when modulated transmission is
selected.
When set to modulated mode, the probe will
only function with one of the following modulated
receivers: OMI-2, OMI-2H, OMI-2C, OMI-2T or
the OSI with OMM-2 system.
Modulated transmission is capable of providing
multiple coded start signals.The OMI-2H, OMI-2T
and the OSI with OMM-2 system allows the use
of multiple probes with one interface.The OMI-
2H and OMI-2T interface enables a twin probe
installation and the OSI with OMM-2 multiple
probe interface system enables up to three
probes to be installed.
Legacy mode
When set to legacy mode, the probe will only
function with an OMI or OMM/MI12.

OLP40 installation guide
2.2
OLP40 basics
Trigger Logic™
All OLP40 settings are configured using the
Trigger Logic™ technique.
Trigger Logic™ (see Section 4 - Trigger Logic™)
is a method that allows the user to view and
select all available mode settings in order to
customise a probe to suit a specific application.
Trigger Logic™ is activated by battery insertion
and subsequent stylus deflection. A sequence
of stylus deflection (triggering) to systematically
lead the user through the available choices to
allow selection of the required mode options.
Current probe settings can be reviewed by
simply removing the batteries for a minimum of
5 seconds, and then replacing them to activate
the Trigger Logic™ review sequence.

2.3
OLP40 basics
Modes of operation
The OLP40 can be in one of three modes:
Standby mode:where the probe is awaiting a
switch on signal:
Operational mode: where the probe has been
activated:
Configuration mode: where Trigger Logic™ may
be used to configure probe settings.
NOTE:
To ensure probe battery life, ensure that the probe does not remain active in the tool changer when
optical on/time out option is selected by observing the LEDs.
Probe switch on Probe switch off
Optical switch on
(When commanded by an
'M' code or machine
output).
Optical off
(When commanded by an 'M' code or machine output).
A timer automatically switches the probe off after 90 minutes from
the last trigger if not turned off by an 'M' code or machine output.
Note:
This method is required when operating a twin probe system
with an OMI-2T or when operating multiple probes with the OSI
with OMM-2 in multiple probe mode.
After being switched on, the OLP40 must be on for 1 second
minimum before being switched off.
Timer off (time out)
Time out will occur (12, 33 or 134 seconds) after the last probe
trigger or reseat.
Optical switch on
(When commanded by
Auto start).
Timer off (time out)
Time out will occur (12, 33 or 134 seconds) after the last probe
trigger or reseat.

Optical switch off
See table page 2.3
Enhanced trigger filter
Probes subjected to high levels of vibration or
shock loads may output signals without having
contacted any surface.The Enhanced trigger filter
improves the probes resistance to these effects.
When the filter is enabled, a constant 10 ms delay
is introduced to the probe output.
The OLP40 is factory set to trigger filter off.
NOTE:
It may be necessary to reduce the probe
approach speed to allow for the increased stylus
overtravel during the extended time delay.
Transmission method/probe
identification
Legacy start filter off/on
If false start problems are experienced in
Legacy mode, activate the Legacy start filter
on option.This introduces a 1 second delay
to the probe switch on time and improves the
probes resistance to false starts caused by light
interference.
Modulated Probe 1/Probe 2
To operate a twin probe system, one probe
needs to be set to Probe 1 start and the other
set to Probe 2 start, these settings are user
configurable.
For most applications the inspection probe
should be set to Probe 1 start. However where
the application uses two inspection probes the
secondary inspection probe is set to Probe 2.
Optical power
Where the separation between the OLP40 and
the receiver is small (no more than 2 metres), the
low optical power setting may be selected, see
pages 3.2/3.3/3.5 and 4.3.This setting will reduce
the optical transmission range and extend battery
life.
The OLP40 is factory set to standard optical
power.

The stylus trigger force is the
force exerted on the component
when the probe triggers.
However, the maximum force
applied to the component will
occur after the trigger point and
will be greater than the trigger
force.The magnitude depends
on a number of factors affecting
probe overtravel including
measuring speed and machine
deceleration.If the forces applied
to the component are critical,
contact Renishaw for further
information.
