OMI
The OMI is an optical transmitter/receiver/interface, which conveys and processes signals between an inspection probe and the CNC machine control
The OMI is an alternative to the OMM receiver + MI 12 interface arrangement

OMI STATUS LEDs
Visual indication of system status is provided by LEDs.
1. LED (Yellow) - START signal status.
Flashes when start signal is transmitted to probe.
2. LED (Red) - Low battery life.
Flashes on and off when probe battery voltage falls below a set level.
3. LED (red, green) - Probe status.
Lit when OMI is powered.
Green - Probe seated.
Red - Probe triggered or an error has occured.
4. LED (red) - Error.
Lit when error condition exists.
e.g. optical beam obstructed/probe out of optical range/probe switched off/battery exhausted.
5. LED (red, yellow, green).
Signal strength received.
Red - No signal, or signal too weak.
Yellow - Marginal signal, system may/maynot operate.
Green Good signal, system will operate correctly.
6. LED (clear x 3 banks).
Transmit control signals to the probe.
7. Sealing gland .
8. Conduit.
9. Cable.

OMI OPTIMUM POSITION SETTING
To assist finding the optimum position for the OMI during system installation, signal strength received is indicated on the red/yellow/green LED (item 5).
WARNING
If two systems are operating in close proximity, take care to ensure that signals transmitted from the OMP on one machine, are not received by the OMI on the other machine, and vice versa. The OMI may have to be shielded from direct light sources.
