The RMI is designed to be mounted within the machine's working envelope. Alternatively, power may be supplied from a Renishaw PSU3 power supply unit. Power supply The RMI can draw its supply from the CNC machine 12 V to 30 V d.c. supply and presents a Input voltage ripple The input voltage ripple shall not cause the voltage to fall below 12 V, or rise above 30 V.

Status is continuously updated and indication is provided for START, LOW BATTERY, PROBE STATUS, ERROR, SIGNAL STRENGTH LED LIGHT SIGNALS 1. LOW BATTERY Red Battery is low. Green M code start/stop in progress. Yellow Battery low & M code start/stop in progress. Off Battery is O.K. (and no M code start/stop in progress). 2. PROBE STATUS Red Probe triggered or unknown status. Green Probe is seated. KEEP THE FRONT COVER CLEAN RMI visual diagnostics Notes. 3. ERROR Red Error, other outputs may be incorrect. Off No Error. 4. SIGNAL Green Full signal strength. Yellow Medium signal strength. Red Low signal strength, radio link may fail. Off No signal detected. Green/off Flashing: RMI is acquisition mode, and can acquire a partner RMP. Red/yellow Flashing: RMI has (just) acquired a new partner RMP. 1. The probe status LED will always be illuminated when power is present. There is no ‘power present’ LED. 2. All the indicators report the status of the partner RMP. If there is no partner in range, or the partner is off then the probe status and error LEDs will be red and the other LEDs will be off. 3. When the RMI is powered it will enter the acquire partner mode which will be indicated by the flashing green signal LED. After a short time (~12 secs) it will switch to its normal mode listening for its partner. 4. The conditions shown by the low battery, probe status and error LEDs are the same as those present on the electrical signal outputs. 8 RMI outputs RMI outputs There are four outputs: Probe status 1 (SSR) Probe status 2a (driven skip 5 V isolated) Probe status 2b (driven at power supply Error (SSR) Low battery (SSR) voltage) SSR 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 the SSR outputs, but may trip the electronic over current circuits. All outputs can be individually inverted by using switches 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. Driven outputs: Sourcing - Up to 50 mA protected. Sinking - Up to 50 mA unprotected, but overload will still be indicated by LEDs. RMI outputs RMI outputs CAUTION: Power supply voltage Do not exceed 30 V between the black wire and the screen wire (grey/black), or the red wire and screen wire (grey/black), or the red and black wires (power supply), as this could result 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 protection for the RMI and cable Screen connection A good connection should be made to machine ground (star point). Output stage circuit Output stage supplies (+ve, –ve) should not be switched on and off to enable/disable them as 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. 10 RMI output waveforms RMI OUTPUTS SSR / driven output (switch position) PROBE STATUS 1 (LEVEL) Normally closed PROBE STATUS 1 (PULSED) Normally closed PROBE STATUS 2 (LEVEL) PROBE Probe switch on Power off SSR open SSR closed SSR open SSR closed Output high Output low Normally low PROBE STATUS 2 (PULSED) Normally low Output high Output low Seated Seated Triggered Probe trigger Probe reseat Error Probe e.g. Error Low switch low signal clear battery off RMI output waveforms RMI output waveforms 11 (outputs can be inverted by switches) PROBE RMI OUTPUTS ERROR Normally closed LOW BATTERY Normally closed Probe Seated Power switch on off Seated Triggered Probe trigger Probe reseat Error Probe e.g. Error Low switch low signal clear battery off SSR open SSR closed SSR open SSR closed SIGNAL DELAYS 1.

To fit a ferrule, insert the prepared core into ferrule, until the end is flush with the end of the ferrule as shown below. Then crimp with pliers. The RMI standard cable is 15 m (49.2 ft) long, longer cables are avaible (see page 25). Core end flush with ferrule Ferrule Core Crimp Cable specification: Ø7.5 mm (0.29 in), 13 core screened cable, each core 18 x 0.1 mm. NOTE: Maximum total cable length is 50 m (164 ft) at 24V 16 RMI cable sealing and fitting flexible conduit RMI cable sealing Coolant and dirt are prevented from entering the RMI by the cable sealing gland. The RMI cable is protected against physical damage by fitting flexible conduit if required. Fitting flexible conduit Recommended flexible conduit is Anamet sealtite HFX (5/16 in) polyeurethane). 1. Cable Slide nut B and plastic olive onto conduit. 2. Screw conduit termination piece into end of conduit. Flexible conduit Adaptor A Conduit termination piece Plastic olive Nut B 3. Fit conduit to adaptor A and tighten nut B. CAUTION: Failure to adequately protect the cable can result in system failure due to either cable 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 between A and B. RMP-RMI partnership 17 System setup/establishing RMP-RMI partnership. Set up is done by using the RMP trigger logic and powering on the RMI at a particular time during the process. 1. 2. 5. Trigger the probe (min 0.1 sec, max 2 sec). 6. When the partnership is established the RMI signal LED will flash red and yellow. Use trigger logic to set RMP turn on/ off modes as desired. 7. Use trigger logic to access RMP acquisition mode (turquoise/light blue flashes 2 short and 1 long). Allow ~10 seconds for both RMP and RMI to timeout, all RMP LEDs off, RMI signal LED off. The system is then ready for use. 8. Note: If the RMP flashes 2 turquoise short followed by 1 red long it is still trying to partner an RMI. WARNING: When holding the RMP do NOT wrap a hand, or anything else, around the glass window. 3. Power on the RMI. 4. Wait until RMI signal led flashes green. Note: When the RMP and RMI become partners the RMI records the RMP serial number. It is not possible for an RMI to be partners with more than one RMP. It is possible for an RMP 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. 18 Installation with inspection and tool setting probe Installation with inspection and tooletting probe On 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 utilised to drive an external relay and effectively select which probe is to be monitored : CONTROL RELAY Probe status from RMI PROBE INPUT Probe status from tool setter M CODE Remote external audible autoput 19 Remote external audible output The pulsed output can be utilized to operate an external remote audible indicator. Wiring configurations are shown below. The audible indicator must comply with the output transistor specification i.e. 50 mA peak 30 V peak Pulse duration is 40 ms ±1 ms. Option 1.

Removing and refitting the RMI cover 21 RMI cover Fitting the RMI cover It is not necessary to remove the RMI from the machine, when adjusting the switches or installing new parts. For torque settings please see page 24. 1. Before fitting the cover, check for any damage to screws or scratch marks which could prevent sealing. Removing the RMI cover 2. Ensure that the 'O' ring seating on the RMI body is clean, and there are no scratch marks which could prevent complete sealing. 1. Clean RMI to ensure no debris enters unit. 2. Unscrew the three captive cover screws evenly (2 mm key). 3. When removing cover DO NOT twist or rotate by hand. Ensure that the cover, antenna contacts and 'O' ring are clean. 4.
