Positioning the thruster - Checkpoints before moulding
Appendix 3.
- Assemble the upper part temporary to the lower part. Check that the
upper part is oriented correct in relation to the lower part (fig 1). Use
approx 6 bolts/nuts evenly distributed.
Do not use seal/sealant at this stage.
- Connect 12 or 24 DC temporarely (refer to the label on actuators for
correct voltage) to the two short 6 mm2 cables on the terminals on the
controller. Set switch no. 4 on the DIP-switch marked “SETTINGS” to
ON during the whole installation procedure. Press “DOWN” to run the
retract mechanism down so that the hatch can be temporary attatched.
Adjust the hatch onto the 4 bolts using the nuts, and check the fit to
the hull by adjusting the position of the unit at the same time as “UP”
and “DOWN” keys are operated. The hatch should have a close fit
along all 4 sides.
- Check that the hatch opens fully without touching the hull. If the
hatch is obstructed by the hull, rotate the unit by lifting it in the aft end
keeping the reference height in front - until the hatch clears the hull.
Do not rotate the unit more than neccesary, 2-3 degrees of rotation
should be sufficient in most cases. The closed position of the hatch
will be alterered automatic by the load sense function when the unit
is lifted in the aft end and the hatch must be angled to fit, turn the the
rear bolts holding the hatch out to compensate.
Before the chamfered sides of the hull and hatch is sealed and filled,
the hatch might protude to far into the hull. This is correct and will
ensure that the hatch is functioning as end stop for the retract mecha-
nism
If the hatch is not closing properly due to the actuators reaching their
end stop, a wedge must be used in each corner between the lower
part and the hull to increase the height so that the hatch is pressed
into the hull opening.

NB! Retract is factory calibrated.
Calibration is only required if 150000 controller is replaced
or position sensor is been loose or replaced.
