8RMI visual diagnostics3. ERRORRed Error, other outputs maybe incorrect.Off No Error.4. SIGNALGreen Excellent communications.Yellow Good communications.Red Poor communications,radio link may fail.Off No signal detected.Green/off Flashing: RMI is inacquisition mode, and canacquire a partner 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/light.2. All the indicators report the status of thepartner RMP60. If there is no partner inrange, or the partner is off then the probestatus and error LEDs will be red and theother LEDs will be off.3. When the RMI is powered it will enter theacquire partner mode which will be indicatedby the flashing green signal LED (no changein outputs). After a short time (~12 secs) itwill switch to its normal mode listening forits partner.4. The conditions shown by the low battery,probe status and error LEDs are the sameas those present on the electrical signaloutputs.
9RMI outputsRMI outputsThere are five outputs:Probe status 1 (SSR)Probe status 2a (5 V isolated driven skip)Probe status 2b (driven at power supplyvoltage)Error (SSR)Low battery (SSR)All outputs can be inverted by using switchesSW1 and SW2 - see section Switches SW1,SW2 and start input.Probe status 1, Error, Low battery (SSR):‘On’ resistance = 50 ohms max.Load voltage = 40 V max.Load current = 100 mA max.continued on next pageProbe status 2a (5 V isolated driven skip):Load current = 50 mA max.Output voltagesSourcing = 4.2 V min at 10 mA.= 2.2 V min at 50 mA.Sinking = 0.4 V max at 10 mA.= 1.3 V max at 50 mA.
10Probe status 2b (driven at power supply voltage):Load current = 50 mA max.Output voltagesSourcing (Voltage supply - Output voltage)= 2.6 V max at 10 mA.= 3.5 V max at 50 mA. Sinking = 2.0 V max at 10 mA.= 2.9 V max at 50 mA.The Low Battery, Probe Status, and Error LEDs willstart flashing red when an output overload has occurred.All outputs will be switched off. If this occurs, turn off thepower supply and remove the source of the problem.Turning on the power supply will reset the RMI.RMI outputs
11RMI outputsCAUTION:Power supply voltageDo not exceed 30 V between the black wire and the screen wire (green/yellow), or thered wire and screen wire (green/yellow), or the red and black wires (power supply), asthis 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 provideprotection for the RMI and cable.Screen 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/disablethem 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.!RMI outputs!!

17RMP60-RMI partnershipcontinued on next pageSystem setup is achieved using trigger logicand powering on the RMI.Trigger logic is a method that allows userconfiguration of the options available in theRMP60. Trigger logic uses a sequence ofRMP60 triggering and battery insertionfollowed by further RMP60 triggering.This leads the user through a series of choicesallowing selection of the required options.Reviewing of choices can be made by batteryinsertion alone. See RMP60 user’s guide forfull details of reviewing probe settings.To partner an RMP60 and RMIPartnering is only required during initial systemset-up. Further partnering is only required ifeither the RMP60 or RMI is changed.Partnering cannot be lost by reconfigurationof probe settings or when changing batteries.Partnering can take place anywhere withinthe operating envelope.RMP60-RMI partnership1. Use trigger logic to access RMP60configuration mode.2. Configure turn on method (if not configured).3. Configure turn off method (if not configured).4. Enter acquisition mode by deflecting stylus.5. Remain in acquisition mode off by notreleasing stylus. This allows time to get theRMI ready for partnering.6. Power on RMI.7. Watch the RMI signal LED; after a coupleof seconds the LED will repeatedly flashon and off green. This is the start of a10 second interval in which the RMIis in acquisition mode.8. Release RMP60 stylus and trigger acouple of times. This causes the RMP60to go into (and out of) acquisition mode.
18 RMP60-RMI partnership9. The RMI signal LED will change torepeatedly flashing red and yellow(for the remainder of the 10 secondinterval) indicating a successfulpartnering.10. Leave RMP60 for 20 seconds to go intostandby.11. System is ready to use.NoteTo check that turn on and off settings have notaccidentally been changed insert batteries toreview current probe settings.NoteWhen holding the RMP60 do NOT wrap a hand,or anything else, around the glass window.NoteWhen the RMP60 and RMI become partnersthe RMI records the RMP60 serial number.It is not possible for an RMI to be partneredwith more than one standard RMP60.It is possible for an RMP60 to be partneredwith more than one RMI, but the system willnot function correctly.

The cablecan be protected against physical damage byfitting flexible conduit if required.Recommended flexible conduit is AnametTMSealtite HFX (5/16 in) polyurethane.A conduit kit is available - see Parts list.RMI cable sealing Fitting flexible conduit1. 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.!Flexibleconduit
22Replacing the RMI cover1. Before replacing the cover, check for anydamage to screws or scratch markswhich could 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 seeScrew torque values.Removing the RMI cover1. Clean RMI to ensure no debris enters unit.2. Unscrew the three cover screws evenly(T10 torx key). Do not remove screwsfrom cover.3. When removing cover, do not twist orrotate by hand.RMI coverRMI cover
