FEATURES ●
●
Modulation transmission for improved rejection of optical interference. Compatible with Renishaw machine probes that use modulated transmission.
●
Toughened glass window.
●
Sealed to IPX8 for machine tool environment.
●
Internal range selection: Reception (RX) 50% or 100% Transmission (TX) 50% or 100% Both factory set to 100%

User configurable inputs: Machine start Machine control M code command (level / pulsed). Auto start Start signal at one second intervals. User configurable outputs: Probe status 1.
SSR. N/O / N/C (level / pulsed).
Probe status 2a.
5 V isolated driven skip (level / pulsed).
Probe status 2b.
Driven at power supply voltage (level / pulsed).
Error SSR.
N/O / N/C.
Low battery SSR. N/O / N/C. OMI-2 OPTIMUM POSITION SETTING To assist finding the optimum position for the OMI-2 during system installation, signal condition 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-2 on the other machine, and vice versa. The OMI-2 may have to be shielded from direct light sources.
Visual indication of system status is provided by LEDs. 1. LED (Yellow) - START signal status. Lit when a start signal is transmitted to the probe. 2. LED (Red) - Low battery life. Lit when probe battery voltage falls below a set level. 3. LED (red, green) - Probe status. Lit when OMI-2 is powered. Green - Probe seated. Red - Probe triggered or an error has occurred. 4. LED (red, blue, violet, yellow) - Error. Indicates transmission error condition e.g. optical beam obstructed / probe out of optical range / probe switched off / battery exhausted. Red
- Signal from probe has either failed or has stopped.
Blue
- A second modulated signal is being received.
Yellow
- Interference or weak probe signal is being received.
Violet
- Interference or a weak probe signal has caused the trigger instant to be delayed.
5. LED (red, yellow, green) - Signal condition. Signal condition received from probe. Red - There is no signal from probe. Yellow - Signal received from probe is either too weak or interference is present. Green - The condition of signal received from probe is good. 6. Sealing gland. 7. Conduit. 8. Cable.

Cable installation ●
Install OMI-2 with cable exiting from lower side for good coolant run off.
●
Cable entry to the OMI-2 is sealed with a gland.
●
Cable protection against physical damage should be provided by flexible conduit.
●
Route the cable away from potential sources of electro magnetic interference.
●
Maintain screen through cable joins.
●
Cable specification Polyurethane Ø7.5 (Ø0.29) 13 core screened cable, each core 18 x 0.1 Standard lengths 8 m (26 ft) or 15 m (49 ft).
