RMI visual diagnostics RMI visual diagnostics A visual indication of system status is provided by LEDs. Status is continuously updated and indication is provided for START, LOW BATTERY, PROBE STATUS, ERROR, SIGNAL STRENGTH LED LIGHT SIGNALS 1. LOW BATTERY / START Red Battery is low. Green M code start/stop in progress. Yellow Battery low and M code start/stop in progress. Off Battery is OK (and no M code start/stop in progress). KEEP THE FRONT COVER CLEAN 2. PROBE STATUS Red Probe triggered or unknown status. Green Probe is seated. Note All LEDs flashing indicates wiring fault or output over-current 8 RMI visual diagnostics Notes. 3. ERROR Red Error, other outputs may be incorrect. Off No Error. 4. SIGNAL Green Excellent communications. Yellow Good communications. Red Poor communications, radio link may fail. Off No signal detected. Green/off Flashing: RMI is in 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/light. 2. All the indicators report the status of the partner RMP60. 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 (no change in outputs). 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. RMI outputs RMI outputs There are five outputs: Probe status 1 (SSR) Probe status 2a (5 V isolated driven skip) Probe status 2b (driven at power supply voltage) Error (SSR) Low battery (SSR) Probe status 2a (5 V isolated driven skip): Load current Output voltages Sourcing Sinking = 50 mA max. = 4.2 V min at 10 mA. = 2.2 V min at 50 mA. = 0.4 V max at 10 mA. = 1.3 V max at 50 mA. All outputs can be inverted by using switches SW1 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 page 10 RMI outputs Probe status 2b (driven at power supply voltage): Load current 50 mA max. Output voltages Sourcing (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 will start flashing red when an output overload has occurred. All outputs will be switched off. If this occurs, turn off the power supply and remove the source of the problem. Turning on the power supply will reset the RMI. RMI outputs RMI outputs CAUTION: Power supply voltage Do not exceed 30 V between the black wire and the screen wire (green/yellow), or the red wire and screen wire (green/yellow), 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. 11 12 RMI output waveforms RMI output waveforms (outputs can be inverted by switches - see section ‘Switches SW1, SW2 and Start Input’) PROBE RMI SSR / driven outputs Probe switch on Power off PROBE STATUS 1 (LEVEL) SSR open Normally open SSR closed PROBE STATUS 1 (PULSED) SSR open Normally open SSR closed ERROR SSR open Normally closed SSR closed Seated Seated Triggered Probe trigger Probe reseat Error Probe e.g. Error Low switch low signal clear battery off RMI output waveforms 13 PROBE RMI SSR / driven outputs LOW BATTERY Normally open Probe Seated switch on Power off Error Probe e.g. Error Low switch low signal clear battery off SSR closed Output high Normally low Output low Normally low Probe reseat SSR open PROBE STATUS 2a/2b (LEVEL) PROBE STATUS 2a/2b (PULSED) Seated Triggered Probe trigger Output high Output low SIGNAL DELAYS 1.

If a negative supply is used then the negative output must be fused. RMP60-RMI partnership 17 RMP60-RMI partnership System setup is achieved using trigger logic and powering on the RMI. Trigger logic is a method that allows user configuration of the options available in the RMP60. Trigger logic uses a sequence of RMP60 triggering and battery insertion followed by further RMP60 triggering. This leads the user through a series of choices allowing selection of the required options. Reviewing of choices can be made by battery insertion alone. See RMP60 user’s guide for full details of reviewing probe settings. To partner an RMP60 and RMI Partnering is only required during initial system set-up. Further partnering is only required if either the RMP60 or RMI is changed. Partnering cannot be lost by reconfiguration of probe settings or when changing batteries. Partnering can take place anywhere within the operating envelope. 1. Use trigger logic to access RMP60 configuration 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 not releasing stylus. This allows time to get the RMI ready for partnering. 6. Power on RMI. 7. Watch the RMI signal LED; after a couple of seconds the LED will repeatedly flash on and off green. This is the start of a 10 second interval in which the RMI is in acquisition mode. 8. Release RMP60 stylus and trigger a couple of times. This causes the RMP60 to go into (and out of) acquisition mode. continued on next page 18 9. RMP60-RMI partnership The RMI signal LED will change to repeatedly flashing red and yellow (for the remainder of the 10 second interval) indicating a successful partnering. 10. Leave RMP60 for 20 seconds to go into standby. 11. System is ready to use. Note To check that turn on and off settings have not accidentally been changed insert batteries to review current probe settings. Note When holding the RMP60 do NOT wrap a hand, or anything else, around the glass window. Note When the RMP60 and RMI become partners the RMI records the RMP60 serial number. It is not possible for an RMI to be partnered with more than one standard RMP60. It is possible for an RMP60 to be partnered with more than one RMI, but the system will not function correctly.
