The wiring of the sensing head cable is color coded, see section 5.4.3
5.4 Wiring, Terminal
You need to connect the power supply and possibly the signal input/output wires. Use only cable with
outside diameter from 4 to 6 mm (0.16 to 0.24 in), wire size: 0.14 to 0.75 mm² (AWG 19 to 26).
The cable must include shielded wires. It should not be used as a strain relief!

Questions and answers
I am currently installing 4 modules, each with 2 of the Raytek MI3 units. 7 of the units arrived with the normal display (Bottom Unit in photo), but 1 has only a full white block in the display. Is this indicative of a failed unit, or would this require external adjustments. These units always work when received, so I am unfamiliar with the required troubleshooting.
