MI16 REAR PANEL CONNECTIONS Connections to the CNC machine control, the power supply and RMM antennae are located on the MI16 rear panel.
MI16 AUDIO DIAGNOSTICS An audio facility, with adjustable volume, is provided on the MI16 Interface to permit the identification of interference sources. With the RMP3 inactive no tone should be audible; only background noise. In either condition the sound should be observed and any unusual sounds noted. In the event of functional disturbances that suggest radio interference, the audio facility should be used: Set the audio volume to maximum, using the buttons on the front panel of the MI16.

Operation outside the temperatures specified for operational use (5°C to 50°C / 41°F to 158°F ) may result in some reduction in transmission range. The maximum recommended distance between the OM16 and RMP3 is 3 metres.

MODES OF OPERATION The RMP3 transmission module can be switched on and off by a number of different methods: All options are selectable on the MI16 interface, and programmed into the RMP3 from the MI16 - see page 26. When a particular option has been selected, all other options are disabled. A standard RMP3 allows any of the options to be selected except the shank switch method, which requires a dedicated shank.
MODE AND CHANNEL SELECTION is carried out on the MI16 and transferred to the RMP3 by a short range optical link. The MI16 Interface and probe/RMP3 transmission module are factory set to Channel 1. The following procedure must be followed to set or change the transmission channel. To program the RMP3 it is necessary to bring the RMP3 close to the front panel of the MI16 Interface. This should be catered for when selecting the MI16 Interface mounting and positioning.
RADIO FREQUENCY and CHANNEL SEPARATION The frequency range is divided into separate channels, each channel having a typical bandwidth of 25kHz, to permit many systems to operate in close proximity without the danger of interference. The operating channel is programmed by push buttons on the MI16. Channel No Frequency MHz Channel No Frequency MHz 1 224.500 21 225.000 2 224.525 22 225.025 3 224.550 23 225.050 4 224.575 24 225.075 5 224.600 25 225.100 6 224.625 26 225.
PROGRAMMING THE RMP3 TRANSMISSION MODULE 1. To enter the RMP3 programming mode, remove the probe battery cover and battery for a period of 10 seconds minimum. 2. Replace the battery cover and battery. A double green flash from the RMP3 STATUS LED indicates the RMP3 is in programming mode. The mode is active for one minute, after which the RMP3 returns to standby status. 3. To program the RMP3 (or check its current programming configuration) align the RMP3 programming LED with those 6.
MAINTENANCE STYLUS SPRING PRESSURE ADJUSTMENT Gauging force Locknut 7mm AF Stop Adjusting screw Stylus 2.5mm AF 2.0mm AF Align contact pins before connecting probe head. DO NOT rotate probe head when located in radio module Spring pressure within the probe causes the stylus to sit in one unique position, and return to this position following each stylus deflection. Stylus pressure is set by Renishaw. The user should only adjust spring pressure in special circumstances e.g.
DIAPHRAGM INSPECTION and REPLACEMENT PROBE DIAPHRAGMS The probe mechanism is protected from coolant and debris by two diaphragms, these provide adequate protection under normal working conditions. The user should periodically check the outer diaphragm, for signs of damage and coolant leakage. If this is evident replace the outer diaphragm. The outer diaphragm is resistant to coolant and oils.
