2.1IntroductionThe RTS is a tool setter with radio transmission suitable for use on small to large machining centres, or where line-of-sight between probe and receiver is difficult to achieve.The RTS forms part of Renishaw’s family of new generation radio transmission probes. It has been designed to comply with worldwide standards 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 RTS 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 indication.Getting startedA multicolour LED provides visual indication of selected probe states:• trigger filter setting;• tool setter status - triggered or seated;• battery condition.Batteries are inserted or removed as shown in Section 5, "Maintenance" page 5.2.On insertion of the batteries, the LED will begin to flash (see Section 4, "Trigger Logic™" page 4.1). System interfaceThe RMI and RMI-Q are combined antenna, interface and receiver units used to communicate between the RTS and the machine controller.Trigger Logic™All RTS 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 uses 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.Modes of operationThe RTS can be in one of three modes:Standby mode: where the RTS is awaiting a switch-on signal.Operational mode: activated by the switch-on method described on the next page, the RTS is ready for use.Configuration mode: where Trigger Logic™ may be used to configure the following probe settings.RTS basics
RTS installation guide2.2RTS basicsConfigurable settingsEnhanced trigger filterProbes subjected to high levels of vibration or shock loads may trigger without having been contacted. The enhanced trigger filter improves the probe’s resistance to these effects.When the filter is enabled, a constant nominal 6.7 ms delay is introduced to the probe output.It may be necessary to reduce the approach speed to allow for the increased stylus overtravel during the extended time delay. The RTS is factory set to Enhanced trigger filter off.Acquisition modeSystem set-up is achieved using Trigger Logic™ and powering on the RMI or RMI-Q.Partnering is only required during initial system set-up. Further partnering is only required if either the RTS or RMI/RMI-Q is changed.Partnering will not be lost by reconfiguration of probe settings or when changing batteries.Partnering can take place anywhere within the operating envelope.Switch-onWhen the RTS is used with an RMI the turn-on time is 1.0 second. When the RTS is used with an RMI-Q the turn-on time can be configured, in the RMI-Q, to either 0.5 seconds or 1.0 second. For best battery life, select 1.0 second turn-on time.A timer automatically switches the probe off 90 minutes after the last trigger if not turned off by an M code.NOTE: After being switched on, the RTS must be on for 1.0 second minimum before being switched off.
2.3RTS basicsOperation Recommended rotating tool feed ratesCutters should be rotated in reverse to the cutting direction. Renishaw tool setting software calculates speeds and feeds automatically using the following information.First touch – machine spindle rev/min Rev/min for the first move against the probe stylus:Diameters below 24 mm, 800 rev/min is used.Diameters from 24 mm to 127 mm, rev/min is calculated using a surface speed of 60 m/min (197 ft/min).Diameters above 127 mm, 150 rev/min is used.First touch – machine feed rateThe feedrate (f) is calculated as follows:f = 0.16 × rev/min f units mm/min (diameter set)f = 0.12 × rev/min f units mm/min (length set)Second touch – machine feed rate800 rev/min, 4 mm/min (0.16 in/min) feedrate.The tool is driven in the machine Z axis for tool length measurements and broken tool detection.Rotating tools are set in the machine’s X and Y axes for tool radius offsets.Screw adjusters allow the stylus to be aligned with the machine’s axes.Software routinesSoftware routines for tool setting are available from Renishaw for various machine controllers and are described in data sheet H-2000-2289.In addition, data sheet H-2000-2298 lists available Renishaw software programs. Both data sheets can be downloaded from www.renishaw.com/inspectionplus.Achievable set-up tolerancesThe tolerances to which tools can be set depend upon the flatness and parallelism of the stylus tip setting. A value of 5 µm (0.0002 in) front to back and side to side is easily achievable over the flat portion of the stylus tip, and 5 µm (0.0002 in) parallelism is easily achievable with the axes of a square tip stylus. This setting accuracy is sufficient for the majority of tool setting applications.StylusZX/YRotate tool in reverse direction for diameter settingXY

3.3System installationPerformance envelope when using the RTS with an RMI/RMI-QRTS - RMI/RMI-Q positioningThe probe system should be positioned so that the optimum range can be achieved over the full travel of the machine's axes. Always face the front cover of the RMI/RMI-Q in the general direction of the machining area and the tool magazine, ensuring both are within the performance envelope shown below. To assist in finding the optimum position of the RMI/RMI-Q, the signal quality is displayed on an RMI/RMI-Q signal LED. Ensure that the signal LED indicates a green or yellow (good) signal strength when the RTS is operating or in stand-by mode (see following note regarding 'hibernate mode').NOTE: RMI/RMI-Q installation with RTS. RTS has a built-in hibernate mode (battery saving mode) that saves battery life when the RMI/RMI-Q is unpowered. The RTS goes into hibernate mode 30 seconds after the RMI/RMI-Q is unpowered (or the RTS is out of range). When in hibernate mode, the RTS checks for a powered RMI/RMI-Q every 30 seconds. If found, the RTS goes from hibernate mode to stand-by mode, ready for an M code. If the RTS goes out of range, for example if the RTS is fitted to a pallet which is removed from the machine, once the RTS is back in range the system will automatically re-synchronise within 30 seconds (worst case). Allowance must be made within the machine controller program for this.Performance envelopeThe RTS and RMI/RMI-Q 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.0°15°15°75°75°60°60°45°45°30°30°10 (33)10 (33)15 (49)15 (49)5 (16)5 (16)RTS SIDE VIEW0°15°75°60°45°30°30°45°60° 75°10 (33)15 (49)5 (16)5 (16)10 (33)15 (49)15°RMI/RMI-Q RTS TOP VIEW5 (16)10 (33)15 (49)75°60°45°30°15° 0° 15°30°30°45°60°75°90° 90°75°60°45°15°45°60°75°0°15°30°Range metres (feet) OPERATING AND SWITCH ON/OFF

This protects the probe mechanism from damage in the event of excessive stylus overtravel or a collision.Captive linkIn the event of the break stem breaking, the captive link ties the stylus to the probe, which prevents the stylus falling into the machine.NOTE: Always hold the support bar in position to counteract twisting forces and avoid over-stressing the stylus break stem.
3.5System installationInstalling the batteriesNOTES: See Section 5, "Maintenance" for a list of suitable battery types. If dead batteries are inadvertently inserted into the probe, the LED will remain a constant red (for details, see Section 4, "Trigger Logic™" page 4.4). Ensure the product is clean and dry before inserting batteries. Do not allow coolant or debris to enter the battery compartment. When inserting batteries, check that the battery polarity is correct. After inserting the batteries, the LED will display the current probe settings (for details, see Section 4, "Trigger Logic™" page 4.1).123

3.13System installationCalibrating the RTSWhy calibrate a probe?A 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 you calibrate your probe 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 crashed;• at regular intervals to compensate for mechanical changes of your machine tool.When your probe is assembled and mounted on the machine table, it is necessary to align the stylus faces with the machine axes to avoid probing errors when setting tools. It is worth taking care with this operation – you should try to get the faces aligned to within 0.010 mm (0.0004 in) for normal use. This is achieved by manually adjusting the stylus with the adjusting screws provided, and using a suitable instrument such as a DTI clock mounted in the machine spindle.When the probe has been correctly set up on the machine, it is time to calibrate the probe. Calibration cycles are available from Renishaw for this task. The purpose is to establish the probe stylus measuring face trigger point values under normal measuring conditions.Calibration should be run at the same speed as probing.The calibration values are stored in macro variables for computation of the tool size during tool setting cycles.Values obtained are axis trigger positions (in machine co-ordinates). Any errors due to machine and probe triggering characteristics are automatically calibrated out in this way. These values are the electronic trigger positions under dynamic operating conditions, and not necessarily the true physical stylus face positions.NOTE: Poor repeatability of probe trigger point values indicates that either the probe/stylus assembly is loose or a machine/probe fault exists. Further investigation is required.

4.3Trigger Logic™RTS – RMI/RMI-Q partnershipSystem set-up is achieved using Trigger Logic™ and powering on the RMI/RMI-Q. Partnering is only required during initial system set-up. Further partnering is only required if either the RTS or RMI/RMI-Q is changed.Partnering will not be lost by reconfiguring the probe settings or when changing batteries. 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, which defaults to "Acquisition mode off".Deflect the stylus to select 'Acquisition mode on'. Ensure this is done within 10 seconds of the RMI/RMI-Q signal LED flashing green.SIGNAL LEDRMI/RMI-Q in acquisition mode33The probe is in stand-by and the system is ready for use.New partner RMP acquiredSIGNAL LED> 20 sAcquisition mode offAcquisition modeAcquisition mode onSwitch on the RMI/RMI-QNOTE: Once in ‘Acquisition mode off’, ensure the next two steps are completed within 20 seconds.< 4 s

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 re-activates 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 repeats itself.
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.Cleaning the probeWipe window of probe with a clean cloth to remove machining residue. This should be done on a regular basis to maintain optimum transmission.5.1Maintenance
RTS installation guide5.2Maintenance CAUTIONS: Do not leave exhausted batteries in the probe. When changing batteries, do not allow coolant or debris to enter the battery compartment. Ensure product is clean and dry before inserting batteries. When changing batteries, check that the battery polarity is correct. Take care to avoid damaging the battery compartment gasket. Only use specified batteries (page 5.3). Please dispose of exhausted batteries in accordance with local regulations. Never dispose of batteries in a fire. Further battery safety information is available on page 1.5.Changing the batteries1243!NOTES: 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 gasket and mating surfaces are clean and free from dirt before reassembly. After removing old batteries wait more than 5 seconds before inserting new batteries. If dead batteries are inadvertently inserted into the probe then the LEDs will remain a constant red.

RTS installation guide5.4MaintenanceRoutine maintenanceThe probe is a precision tool and must be handled with care.Ensure the probe is firmly secured to its mounting.The probe requires minimal maintenance as it is designed to operate as a permanent fixture on CNC machining centres, where it is subject to a hot chip and coolant environment.1. Do not allow excessive waste material to build up around the probe.2 Swarf accumulating on the transmission window will have a detrimental effect on transmission performance, see page 5.1. 3. Keep all electrical connections clean.4. The probe mechanism is protected by an outer metal eyelid seal and an inner flexible diaphragm seal. Approximately once a month, inspect the probe inner diaphragm seal, see page 5.5. If it is pierced or damaged please contact Renishaw.The service interval may be extended or reduced depending on experience. SpringFront coverO ringInner diaphragm sealMetal eyelid sealProbe module
5.5MaintenanceInspecting the inner diaphragm seal1. Remove the stylus/break stem assembly using the 5 mm AF spanner.2. Use a 24 mm or 15/16 in spanner to remove the probe’s front cover. This will expose the metal eyelid seal, spring and the inner diaphragm seal. Remove the metal eyelid and spring.

Wash inside the probe, using clean coolant. (DO NOT use sharp objects to clean out debris).4. Inspect the diaphragm seal for signs of piercing or damage. In the event of damage, return the probe to your supplier for repair, as coolant entering the probe mechanism could cause the probe to fail.5. Refit the spring and metal eyelid (the spring’s largest diameter is against the metal eyelid).6. Refit the remaining components.
