2.12.1IntroductionWelcome to the RLP40 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.RMP40 forms part of Renishaw's family of new generation radio transmission probes, It is ideally suited to large machining centres, where line-of-sight between probe and receiver is difficult to achieve or where Z travel is limited.RLP40 complies with FCC regulations and operates in the 2.4 GHz band. It delivers interference-free transmission through the use of FHSS (Frequency Hopping Spread Spectrum). This allows many systems to operate in the same machine shop without risk of cross-interference.All RLP40 settings are configured using ‘Trigger Logic’. This technique enables the user to review and subsequently change probe settings by deflecting the stylus whilst observing the LED display.Configurable settings are:• Radio on / Radio off• Radio on / Timer off• Spin on / Spin off• Spin on / Timer off• Filter on / Filter off• Multiple probe mode on / multiple probe mode offGetting startedThree multicolour LEDs provide visual indication of selected probe settings.For example:• Switch-on and switch-off methods• Probe status - triggered or seated• Battery conditionBatteries are inserted or removed as shown (see ‘RLP40 batteries’ for further information). On insertion of batteries, the LEDs will begin to flash (see ‘Reviewing current probe settings’ for further information).System interfaceThe RMI integrated interface/receiver is used to communicate between the RLP40 probe and the machine control.RLP40 basics
RLP40 installation guide2.2RLP40 basicsTrigger Logic™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) is then used 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.Modes of operationThe RLP40 probe can be in one of three modes:Standby mode: where the probe is awaiting a switch on signal.Operational mode: activated by one of the switch on methods described on this page. In this mode the RLP40 is ready for use.Configuration mode: where Trigger Logic™ may be used to configure the following probe settings.Configurable settingsSwitch on/switch off methodsThe following switch on/switch off options are user-configurable.1. Radio on/Radio off2. Radio on/Timer off3. Spin on/Spin off4. Spin on/Timer offEnhanced trigger filterProbes 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 RLP40 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.
2.3RLP40 basicsRLP40 switch on methodSwitch on options are configurableRLP40 switch off methodSwitch off options are configurableSwitch on timeRadio onRadio switch on is commanded by machine input.Radio offRadio switch off is commanded by machine input. A timer automatically switches the probe off 90 minutes after the last trigger if it is not turned off by machine input.Timer off (timeout)Timeout will occur 12, 33 or 134 seconds (user configurable) after the last probe trigger or reseat.1 second maximum Note: This assumes a good radio communication link. In a poor RF environment this may rise to a maximum of 3 seconds.Spin onSpin at 500 rev/min for 1 second minimum (6 seconds maximum).Spin offSpin at 500 rev/min for 1 second minimum (6 seconds maximum). A timer automatically switches the probe off 90 minutes after the last trigger if it is not spun.Timer off (timeout)Timeout will occur 12, 33 or 134 seconds (user configurable) after the last probe trigger or reseat.2 seconds maximum. Note: The 2 seconds starts from the moment the spindle reaches 500 rev/min.NOTE: After being switched on, the RLP40 must be on for 1 second minimum (the RLP40 must be spun down before it can be spun off again) before being switched off.
RLP40 installation guide2.4RLP40 basicsMultiple probe modeThe RLP40 can be configured, using Trigger Logic™, to allow multiple radio probes to be used with a single RMI.NOTES: The 'radio on' switch on method cannot be used in multiple probe mode. Multiple probe mode will not appear as an option if the 'radio on' option has been selected. RLP40 probes which are set to 'multiple probe mode on' can coexist alongside any number of RLP40 probes set to 'mode off'.To allow multiple radio probes to work in close proximity, and with a single RMI, 16 choices of 'mode on' colours are available, each representing a different machine tool installation. The colour choices available are as shown on page 4.2. All probes operating with a single RMI must be set to the same 'mode on' colour choice; any multiple probes located on adjacent machines must all be set to an alternative 'mode on' colour choice.Only one probe per 'mode on' colour choice needs to be partnered with the RMI as, by configuring multiple probes to a single 'mode on' colour choice, all probes using this 'mode on' colour choice will have the same identity. The probe to be partnered is partnered after selecting the 'multiple probe mode' setting and choosing the 'mode on' option. See 'Changing the probe settings' in Section 4, "Trigger Logic™".There is no limit to the number of probes that can be used with a single RMI so long as they all have the same 'mode on' colour choice.All RLP40 probes are factory set to 'mode off'.The addition of any further probe(s) into a single probe installation will require that all probes are reconfigured to the same 'mode on' colour choice and that one of the probes is then repartnered with the RMI.The addition of any further probe(s), or replacements, into a multi-probe installation can be achieved simply through the reconfiguration of the probe to the same 'mode on' colour choice.Acquisition modeSystem set-up is achieved using Trigger Logic™ and powering on the RMI.Partnering is only required during initial system set-up. Further partnering is only required if either the RLP40 or RMI is changed.Partnering will not be lost by reconfiguration of probe settings or when changing batteries, except where multiple probe mode is selected.Partnering can take place anywhere within the operating envelope.

This allows easy installation, either inside or outside the machine enclosure.Coolant and swarf residue accumulating on the RLP40 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 either the RMI cover or the probe glass window with your hand, as this will affect the performance.Some reduction in range may result when operating in temperatures of 0 °C to 5 °C (32 °F to 41 °F) and 50 °C to 60 °C (122 °F to 140 °F).

RLP40 has a built-in hibernate mode (battery saving mode) that saves battery life when the RMI is unpowered in radio-on (radio-off or time-off) configurations. The RLP40 goes into hibernate mode 30 seconds after the RMI is unpowered (or the RLP40 is out of range). When in hibernate mode, the RLP40 checks for a powered RMI every 30 seconds. If found, the RLP40 goes from hibernate mode to stand-by mode, ready for radio-on.Performance envelopeThe RLP40 and RMI must be within each other's performance envelope as shown below. The performance envelope shows line-of-sight performance, however radio transmission does not require this providing a reflected path (of less than 15 m (49.2 ft)) is available.

3.7System installationStylus trigger force adjustmentSpring force within the probe causes the stylus to sit in a unique position and return to this position following each stylus deflection.Stylus trigger force is set by Renishaw. The user should only adjust trigger force in special circumstances e.g. where there is excessive machine vibration or insufficient force to support the stylus weight.To adjust the trigger force, turn the adjusting screw anticlockwise (as shown) to reduce the force (more sensitive); eventually it reaches a stop. Turn the adjusting screw clockwise (as shown) to increase the force (less sensitive). If the internal screw becomes disengaged, remove any pressure on the stylus and turn the key anticlockwise to re-engage the thread.Trigger forces in the XY plane vary around the stylus and depend on trigger direction.Stylus trigger force adjustment and use of styli other than test stylus types may cause probe repeatability to differ from the calibration certificate results.Factory settingXY low force 0.4 N / 40 gf (1.4 ozf)XY high force 0.8 N / 80 gf (2.8 ozf)Z 5.3 N / 530 gf (18.7 ozf)Maximum settingXY low force 0.8 N / 80 gf (2.8 ozf)XY high force 1.6 N / 160 gf (5.6 ozf)Z 10.0 N / 1000 gf (36.3 ozf)Minimum settingXY low force 0.3 N / 30 gf (1.1 ozf)XY high force 0.6 N / 60 gf (2.1 ozf)Z 4.0 N 400 gf (14.1 ozf)2 mm AFReduceforceIncreaseforce
RLP40 installation guide3.8System installationCalibrating the RLP40Why calibrate a probe?A spindle probe is just one component of the measurement system which communicates with the machine tool. Each part of the system can introduce a constant difference between the position that the stylus touches and the position that is reported to the machine. If the probe is not calibrated, this difference will appear as an inaccuracy in the measurement. Calibration of the probe allows the probing software to compensate for this difference.During normal use, the difference between the touch position and the reported position does not change, but it is important that the probe is calibrated in the following circumstances:• when a probe system is to be used for the first time;• when a new stylus is fitted to the probe;• when it is suspected that the stylus has become distorted or that the probe has been crashed;• at regular intervals to compensate for mechanical changes of your machine tool;• if repeatability of relocation of the probe shank in the machine spindle is poor. In this case, the probe may need to be recalibrated each time it is selected.It is good practice to set the tip of the stylus on-centre, because this reduces the effect of any variation in spindle and tool orientation (see page 3.6). A small amount of run-out is acceptable, and can be compensated for as part of the normal calibration process.Three different operations are to be used when calibrating a probe. They are:• calibrating either in a bored hole or on a turned diameter of known size;• calibrating either in a ring gauge or on a datum sphere;• calibrating the probe length.Calibrating in a bored hole or on a turned diameterCalibrating a probe, either in a bored hole or on a turned diameter of known size, automatically stores offset values between actual and theoretical stylus ball position and also the electronic ball radius of the stylus of the stylus being used. The stored values are then used automatically in the measuring cycles. Measured values are compensated by these offsets so that positional and size measurements relative to spindle centre line are accurate. Calibrating in a ring gauge or on a datum sphereCalibrating a probe either in a ring gauge or on a datum sphere with a known diameter automatically stores one or more value for the radius of the stylus ball. The stored values are then used automatically by the measuring cycles to give the true size of the feature. The values are also used to give true positions of single surface features.NOTE: The stored radius values are based on the true electronic trigger points. These values are different from the physical sizes.Calibrating the probe lengthCalibrating a probe on a known reference surface automatically stores the position of the stylus ball (probe length or geometry offset) relative to either a turret or workpiece reference face.

Once acquisition has been successful, the RLP40 will revert to ‘Acquisition mode off’.NOTE: Further probes used require the same multiple probe mode setting, but do not need to be partnered with the RMI.Cease triggering here, unless the multiple probe mode is required in which case deflect stylus > 4 secondsNOTE: If no changes are made in multiple probe mode, then deflecting the stylus for more than 4 seconds will return the probe settings to ‘To change switch-on method’NOTE: To partner a RLP40 with a RMI, please see RLP40 - RMI partnership.Acquisition modeoffAcquisition modeMultiple probe mode (omitted for radio-on) (See ‘Multiple probe mode settings’ to view all 16 choices)Mode off Mode onReturn to “Change switch-on method”Acquisition modeonMachine 1 Machine 2 Machine 16Acquisition mode offAcquisition modeAcquisition mode onNew settings complete
RLP40 installation guide4.6Trigger Logic™RLP40 – RMI partnershipSystem set-up is achieved using Trigger Logic™ and powering the RMI. Partnering is only required during initial system set-up. Further partnering is only required if either the RLP40 or RMI is changed, or a system is reconfigured for multiple probes (multiple probe mode).Partnering will not be lost by reconfiguring the probe settings or when changing batteries, except where multiple probe mode is selected. Partnering can take place anywhere within the operating envelope.In configuration mode, configure the probe settings as required until you reach the "Acquisition mode" menu. Select "Acquisition mode off".Deflect the stylus to select 'Acquisition mode on'. Ensure this is done within 10 seconds of the RMI signal LED flashing green.SIGNAL LEDRMI in acquisition mode33The probe is in stand-by and the system is ready for use.3XNew partner RMP acquiredSIGNAL LED> 20 sAcquisition mode offAcquisition modeAcquisition mode on NOTE: Once in ‘Acquisition mode off’, ensure the next two steps are completed within 20 seconds.Switch on the RMI< 4 sX3
4.7Trigger Logic™Operating modeNOTE: 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 page 4.1).4. Again, the batteries discharge and the probe ceases to function.5. Again, the batteries recover sufficiently to provide the probe with power, and the sequence is repeated.LED colour Probe status Graphic hintFlashing green Probe seated in operating mode Flashing red Probe triggered in operating mode Flashing green and blue Probe seated in operating mode – low battery Flashing red and blue Probe triggered in operating mode – low battery Constant red Battery deadFlashing red orFlashing red and green orSequence when batteries are insertedUnsuitable battery LEDs flashing greenLEDs flashing redLEDs flashing redX/Y ZProbe status LEDs

5.1MaintenanceCleaning the probeWipe the window of the probe with a clean cloth to remove machining residue. This should be done on a regular basis to maintain optimum transmission.MaintenanceYou may undertake the maintenance routines described in these instructions.Further dismantling and repair of Renishaw 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.
RLP40 installation guide5.2MaintenanceChanging the batteries12! CAUTIONS: Do not leave exhausted batteries in probe. When changing batteries, do not allow coolant or debris to enter the battery compartment. When changing batteries, check that the battery polarity is correct. Take care to avoid damaging the battery cassette gasket. Only use specified batteries (page 5.3).NOTES: After removing the old batteries, wait more than 5 seconds before inserting the new 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 cassette gasket and 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. CAUTIONS: Please dispose of exhausted batteries in accordance with local regulations. Never dispose of batteries in a fire.!

RLP40 installation guide5.4MaintenanceRLP40 eyelidThe RLP40 is fitted with a metal eyelid that protects the internal components of the probe from hot chip and coolant environment. Dirt may accumulate in the cavity underneath the metal eyelid seal. To remove this dirt, once a month, remove the front cap (using a coin or flat blade screwdriver) and then remove all of the residue with a low-pressure jet of coolant. A1324Do not use a sharp tool or a degreasing agent. The cleaning interval may be extended or reduced, depending on the rate dirt accumulates. If the inner diaphragm is damaged, return the probe to your supplier for repair.Re-assembling the probeDO NOT use the probe with the cap removed. Check that the probe is firmly secured in its mounting.Apply coin or flat blade screwdriver to both sides to sequentially lever front cap from probe body
