Notes.
1) The screens of the sensor's emitter, receiver and cleaner cables must be enclosed in yellow/green sleeving and
connected to the earth (groud) stud fitted to the transmitter case closest to the cable's entry point – see Fig A.1.
2) Dual input versions – connect each sensor to the correct input terminals (A or B) as indicated on the sensor's
cables.
3) Use the three-hole cable gland provided with the sensor for the sensor cables.
4) Fit a link between C3 and C5. This stops a false Cleaner Fail messages occuring, as the 7320 system cleaner
module does not generate the Cleaner Acknowledge signal used in the AV400 for the Cleaner Fail Diagnostic.
5) Remove the existing tag from the green wire and fit an eyelet tag. Connect the green wire (Cable 2) to the AV400
Transmitter earth (ground) stud.
