2. Fit the port coil triad to the port end of the mounting bar where the machined flats give the bar
an octagonal cross section. Locate the coil assembly so that the mounting bar engages in the
lateral groove at the bottom of the centre support block. There are arrows on the coil identifica-
tion label to show the forward direction of the coil triad.
3. Use a clamping block to secure the bottom of the port coil triad to the mounting bar. Use a
6mm hexagonal key to tighten the four M8 bolts
lightly
. Do not tighten these bolts fully until you
have installed the complete coil array and you have set the coil separation distance.
4. Follow the same procedure and fit the starboard coil triad to the starboard end of the mounting
bar.
5. The design of the mounting bar allows you to adjust the distance between the coil triads while
maintaining their alignment.
Slide the two coil triads on the mounting bar until they are at the desired separation distance (between
1m and 1.76m). Make certain the coils are equally spaced about the ROV centre line. Tighten all the
securing bolts of both clamping blocks evenly.
Do not over tighten these bolts.
