4RMIThe RMI is a combined radio tranceiver andmachine interface.The RMI is designed to be mounted withinthe machine's working envelope.Power supplyThe RMI can draw its supply from the CNCmachine 12 V to 30 V d.c. supply and presents aRMIpeak load of up to 250 mA during turn on(typically 100 mA from 24 V).Alternatively, power may be supplied froma Renishaw PSU3 power supply unit.Input voltage rippleThe input voltage ripple shall not cause thevoltage to fall below 12 V, or rise above 30 V.RMI46 (1.81)97 (3.82)46 (1.81)45 (1.77)44 (1.73)50 (1.97)74 (2.91)17.5 (0.69)dimensions mm (in)45°4 holes M5 x 13deep on 80 p.c.d.To use a flush rearexit a 25 (1.0) holeis required forconnector

7RMI visual diagnostics3. ERRORRed Error, other outputs maybe incorrect.Off No Error.4. SIGNALGreen Full signal strength.Yellow Medium signal strength.Red Low signal strength, radiolink may fail.Off No signal detected.Green/off Flashing: RMI is acquisitionmode, and can acquire apartner RMP.Red/yellow Flashing: RMI has (just)acquired a new partner RMP.Notes.1. The probe status LED will always beilluminated when power is present.There is no ‘power present’ LED.2. All the indicators report the status of thepartner RMP. If there is no partner in range,or the partner is off then the probe statusand error LEDs will be red and the otherLEDs will be off.3. When the RMI is powered it will enter theacquire partner mode which will be indicatedby the flashing green signal LED.After a short time (~12 secs) it will switch toits normal mode listening for its partner.4. The conditions shown by the low battery,probe status and error LEDs are the sameas those present on the electrical signaloutputs.
8RMI outputsThere are four outputs:Probe status 1 (SSR)Probe status 2a (driven skip 5 V isolated)Probe status 2b (driven at power supplyvoltage)Error (SSR)Low battery (SSR)All outputs can be individually inverted by usingswitches SW1 and SW2 - see pages 16 and 17.Switching time = Less than 10 µs (low to high)Switching time = Less than 10 µs (high to low)If overload occurs, remove source or problem,turn off power supply and the unit will reset itself..RMI outputsSSR outputs:DC ‘ON’ resistance 60 ohms max.Up to 50 mA protected.Switching time = Less than 10 µs (low to high)Switching time = Less than 10 µs (high to low)Power supply reversal will not damage theSSR outputs, but may trip the electronicover current circuits.Driven outputs:Sourcing - Up to 50 mA protected.Sinking - Up to 50 mA unprotected, butoverload will still be indicated byLEDs.
9RMI outputsCAUTION:Power supply voltageDo not exceed 30 V between the black wire and the screen wire (grey/black), or the redwire and screen wire (grey/black), or the red and black wires (power supply), as this couldresult in permanent damage to the RMI and/or the customer power supply.The use of in-line fuses at the machine cabinet end is recommended to provide protectionfor the RMI and cableScreen connectionA good connection should be made to machine ground (star point).Output stage circuitOutput stage supplies (+ve, –ve) should not be switched on and off to enable/disable themas this can cause the over current protection to switch off the output completely.Ensure that outputs from the RMI do not exceed specified current ratings.!RMI outputs!!

15Core end flushwith ferruleCoreFerruleCrimpCable terminationA ferrule should be crimped onto each cablecore for more positive connection at the terminalbox. To fit a ferrule, insert the prepared core intoferrule, until the end is flush with the end of theferrule as shown below. Then crimp with pliers.NOTE:Maximum total cable length is 50 m (164 ft) at 24VStandard cableThe RMI standard cable is 15 m (49.2 ft) long,longer cables are avaible (see page 25).Cable specification:Ø7.5 mm (0.29 in), 13 core screened cable,each core 18 x 0.1 mm.RMI cableRMI cable
16 RMI cable sealing and fitting flexible conduitFitting flexible conduitCableFlexibleconduitAdaptor AConduit terminationpiecePlastic oliveNut BCAUTION: Failure to adequately protect the cable can result in system failure due to eithercable damage or coolant ingress through cores into the RMI.Failure due to inadequate cable protection will invalidate the warranty.When tightening or loosening nut B onto conduit ensure that torque is only applied betweenA and B.Coolant and dirt are prevented from entering theRMI by the cable sealing gland. The RMI cableis protected against physical damage by fittingflexible conduit if required.RMI cable sealing!Recommended flexible conduit is Anametsealtite HFX (5/16 in) polyeurethane).1. Slide nut B and plastic olive onto conduit.2. Screw conduit termination piece into end ofconduit.3. Fit conduit to adaptor A and tighten nut B.
17Set up is done by using the RMP trigger logicand powering on the RMI at a particular timeduring the process.1. Use trigger logic to set RMP turn on/ offmodes as desired.2. Use trigger logic to access RMP acquisitionmode (turquoise/light blue flashes 2 shortand 1 long).System setup/establishing RMP-RMI partnership.RMP-RMI partnership3. Power on the RMI.4. Wait until RMI signal led flashes green.WARNING:When holding the RMP do NOT wrap ahand, or anything else, around the glasswindow.!5. Trigger the probe (min 0.1 sec, max 2 sec).6. When the partnership is established theRMI signal LED will flash red and yellow.7. Allow ~10 seconds for both RMP and RMIto timeout, all RMP LEDs off, RMI signalLED off. The system is then ready for use.8. Note: If the RMP flashes 2 turquoise shortfollowed by 1 red long it is still trying topartner an RMI.Note:When the RMP and RMI become partners theRMI records the RMP serial number. It is notpossible for an RMI to be partners with more thanone RMP.It is possible for an RMP to be partners with morethan one RMI, but the system will notwork correctly if more than one partner RMI ispowered on at any one time.
18On machines where the RMI is to be integrated with a tool setting probe input,and only one probe input is provided on the control, an M code can be utilisedto drive an external relay and effectively select which probe is to be monitored :CONTROLPROBE INPUTM CODEInstallation with inspection and tooletting probeProbe statusfrom tool setterProbe statusfrom RMIRELAYInstallation with inspection and tool setting probe

21Fitting the RMI cover1. Before fitting the cover, check for anydamage to screws or scratch marks whichcould prevent sealing.2. Ensure that the 'O' ring seating on the RMIbody is clean, and there are no scratchmarks which could prevent completesealing.3 Ensure that the cover, antenna contactsand 'O' ring are clean.4. Place cover complete with 'O' ringonto the RMI body.Note :The 'O' ring should be lubricated withsilicone grease to prevent nicking.Do not get any grease on the antennacontacts.5. Tighten each captive screw a few turns ata time, to pull the cover down evenly.Screw torque is 1.4 Nm (1.03 lbf.ft).It is not necessary to remove the RMI fromthe machine, when adjusting the switches orinstalling new parts. For torque settings pleasesee page 24.Removing the RMI cover1. Clean RMI to ensure no debris enters unit.2. Unscrew the three captive cover screwsevenly (2 mm key).3.
