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.
RMI outputs 9 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.
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.
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).

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.
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.
Remote external audible output Remote external audible output Any output (set to pulsed) can be utilised to operate an external remote audible indicator. Wiring configurations are shown below. The audible indicator must comply with the output transistor specification. i.e. up to 50 mA. up to 30 V. Red RMI Option 1. Turquoise Turquoise / Black SSR output 0 V Black +ve –ve RMI Option 2. Using 5 V output Option 3.
20 RMI cable RMI cable Cable termination Standard cable A ferrule should be crimped onto each cable core for more positive connection at the terminal box. The RMI standard cable is 15 m (49.2 ft) long, longer cables are available - see Parts list. Cable specification: Ø7,5 mm (0.29 in), 13 core screened cable, each core 18 x 0,1 mm.
RMI cable sealing and fitting flexible conduit RMI cable sealing 21 Fitting flexible conduit Coolant and dirt are prevented from entering the RMI by the cable sealing gland. The cable can be protected against physical damage by fitting flexible conduit if required. Recommended flexible conduit is AnametTM Sealtite HFX (5/16 in) polyurethane. A conduit kit is available - see Parts list.
22 RMI cover RMI cover Replacing 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 see Screw torque values. 1. Before replacing 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.
