Information to the equipment installer

All Renishaw equipment is designed to comply

Before you begin

with the relevant EC 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 1.5

position away from any potential sources
of electrical noise, i.e. power transformers,
servo drives etc;

• all 0 V/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, i.e. motor power supply
cables etc, 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.

Probe modes
The OMP60 probe can be in one of three modes:

Operational mode – When activated by one of

the switch‑on methods, the probe is switched on

Note 1 Performance specification is tested at a standard test velocity of 480 mm/min (18.9 in/min) with ceramic

Note 2 Trigger force, which is critical in some applications, is the force exerted on the component by the stylus
when the probe triggers.
The maximum force applied will occur after the trigger point, i.e. overtravel. The force value depends on
related variables, including measuring speed and machine deceleration.

Stylus trigger force is set by Renishaw. The user

should only adjust the trigger force in special

machine vibration or insufficient force to support
the stylus weight.

To adjust the trigger force, turn the adjusting

screw anticlockwise to reduce the force (more

Sequence when batteries are inserted

NOTE: Due to the nature of Lithium Thionyl

Chloride batteries, if a ‘low battery’ LED sequence
is ignored or overlooked, then it is possible for the
following sequence of events to occur:

1. When the probe is active, the batteries

discharge until battery power becomes too low
for the probe to operate correctly.
2. The probe stops functioning, but then
reactivates as the batteries recover sufficiently
to provide the probe with power.
3. The probe begins to run through the LED
review sequence (see ‘Reviewing the current
probe settings’ in Section 4 – “Trigger
Logic™”).
4. Again, the batteries discharge and the probe
ceases to function.
5. Again, the batteries recover sufficiently

equipment is a highly specialised operation,
which must be carried out at authorised Renishaw
Service Centres.

Equipment requiring repair, overhaul or attention

under warranty should be returned to your
supplier.

CAUTION: The OMP60 has a glass window,
handle with care if broken to avoid injury.

Changing the batteries

1 ! CAUTIONS:
Maintenance

Do not leave dead batteries in the probe.

When changing batteries, do not allow coolant or

debris to enter the battery compartment.

When changing batteries, check that the battery

5.2
polarity is correct.

Take care to avoid damaging the battery cassette

gasket.

Only use specified batteries.

2 ! CAUTION: Please dispose of dead batteries

in accordance with local regulations. Never
dispose of batteries in a fire.
3 NOTES:

After removing the old batteries, wait more than 5

seconds before inserting the new batteries.

Maintenance
Do not mix new and used batteries or battery
types, as this will result in reduced life and
damage to the batteries.

Always ensure that the cassette gasket and

5.3
mating surfaces are clean and free from dirt
before reassembly.

If dead batteries are inadvertently inserted into

the probe, the LEDs will remain a constant red.

Maintenance

1 Nm (0.74 lbf.ft)
The probe mechanism is protected from coolant
and debris by two diaphragms. These provide Cover
adequate protection under normal working
conditions.
5.4 Outer
You should periodically check the outer diaphragm diaphragm
for signs of damage. If this is evident, replace the
outer diaphragm. Inner
diaphragm
Do not remove the inner diaphragm. If it is
damaged, return the probe to your supplier for
repair.

Outer diaphragm inspection

1. Remove the stylus.

2. Undo the three M3 front cover screws and

remove the front cover.

3. Inspect the outer diaphragm for damage.

4. To remove the outer diaphragm, grip by the

outer edge and pull off.

Inner diaphragm inspection

Inspect the inner diaphragm for damage. If it is

damaged, return the probe to your supplier. DO
NOT REMOVE THE INNER DIAPHRAGM AS
YOUR WARRANTY WILL BE INVALIDATED.

Outer diaphragm replacement

1 Fit the new diaphragm over the centre.

2. Locate the outer edge of the diaphragm

to rest on the outer edge of the inner
diaphragm.

3. Refit the front cover and M3 screws.

4. Refit the stylus and recalibrate the probe.
