Operating envelope
Surfaces within the machine may increase the
signal transmission range.
Coolant and swarf residue accumulating on the
RMP60 and RMI may have a detrimental effect
on transmission performance. Wipe clean as
often as is necessary to maintain unrestricted
transmission.
When operating, do not touch with your hand,
either the RMI cover or the probe glass window,
as this will change the performance.
Operation in extremes of temperature will result
in some reduction in range.
RMI position
To assist finding the optimum position of the RMI
during system installation, a signal strength
indication LED is available on the RMI interface.
RMI signal strength is displayed on an RMI
multi-coloured LED.

The RMP60 probe can be in one of three modes:
1. Stand-by mode - The RMP60 is waiting for
a switch-on signal .
2. Operating mode - Activated by one of the
switch on methods described on this page.
In this mode and the RMP60 is now ready
for use.
3. Configuration mode - The trigger-logic
configuration method allows a number of
RMP60 set-up options to be configured by
triggering the RMP60, including the switch-off
options described on page 25.
Modes of operation
Modes of operation
RMP60 switch-on
RMP60 power on/off
Switch-on options are configurable
- see page 13.
Three switching methods can be used.
1. Radio start
Radio switch-on is commanded by
M code.
2. Spin start
Spin at 650 rev/min for 1 sec minimum
(maximum 6 sec)
3. Shank switch
Note:
RMP60 will be turned on after 1 sec in all
modes.

11
Modes of operation
RMP60 switch-off
Switch-off options are programmable
Three switching methods can be used.
1. Radio stop
Radio switch off is commanded by a
M code.
(Only applies when radio turn on is
selected).
A timer automatically switches the probe off
after 90 min from last trigger if not turned off
by M-code.
2. Timer off (time out)
(Only applies when radio on/spin on
mode is selected).
The RMP60 will time out (12, 33 or
134 sec) after the last probe trigger or
reseat.
3. Spin stop
(Only applies when spin on mode is
selected).
A timer switch automatically swiches
the probe off after 90 min from last
trigger off, if not spun off.
4. Shank switch
(Only applies when shank on mode is
selected).
Note:
After being turned on, the RMP60 must be
on for a minimum of 1 sec (7 sec for spin
off) before being turned off.

Setup is done by using the RMP60 trigger logic
and powering on the RMI at a particular time
during the process.
Trigger logic is a method that allows user
configuration of the options available in the
RMP60. Trigger logic uses a sequence of
RMP60 triggering and battery insertion
followed by further RMP60 triggering.
This leads the user through a series of choices
allowing selection of the required options.
Reviewing of choices made can be made by
battery insertion alone. See pages 12 and 13 for
full details of reviewing probe settings and
configuration using trigger logic.
1. Use trigger logic to set RMP60 turn on/ off
modes as desired.
2. Use trigger logic to access RMP60
acquisition mode (light blue flashes, 2 short
1 long).
System setup/establishing RMP60-RMI partnership.
RMP60-RMI partnership
3. Power on the RMI.
4. Wait until RMI signal led flashes green.
5. Trigger the probe (min 0.1 sec max 2 sec)
RMP60 will flash 2 x turquoise short,
followed by 1 red long and repeat until
acquistion occurs.
6. RMI pattern will change to red & yellow
flashing when it acquires the RMP.
7. Allow ~10 seconds for both RMP60 and
RMI to timeout all RMP60 LEDs off and RMI
signal LED off. The system is then ready for
use.
Warning
When holding the RMP60 do NOT wrap
a hand, or anything else, around the
glass window.

Note.
When the RMP60 and RMI become partners the
RMI records the RMP60 serial number. It is not
possible for an RMI to be partners with more
than one RMP60.
It is possible for an RMP60 to be partners with
more than one RMI, but the system will not
work correctly if more than one partner RMI is
powered on at any one time.

RMP60 batteries
Replacing batteries
Only use specified batteries.
Clean and dry RMP60 with a cloth or paper towel
before removing battery cover. Where the
RMP60 has been exposed to coolant, it is
recommended that the area around the battery
cover is cleaned.
To access the RMP60 batteries, remove the
battery cover by rotating the securing screw
30° anticlockwise and withdraw battery cassette.
Take care to avoid damaging the cover gasket.
When inserting the batteries, ensure they are
loaded as shown (see next page).
If one or more batteries are incorrectly loaded
the probe will not respond.
RMP60 batteries
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 cover gasket and mating
surfaces are clean and free from damage, before
reassembly.

18
DO NOT leave exhausted batteries in probe
DO NOT allow coolant or debris to enter the
battery compartment
DO check for correct battery polarity
RMP60 batteries
Please dispose of exhausted batteries
in accordance with local regulations.
Do not dispose of batteries in fire.
