4.6 - Adjustment procedure

WARNING: the following procedure must be carried out by qualified personnel.
WARNING: presence of moving mechanical parts. Pay extreme attention when operating on the BTR propeller if con-
nected to power.
• Ensure that all electrical connections have been properly carried out.
• Remove the cover from the board box (fig.17).
Limit switch adjustments must be made in "manual mode".
• Holding down both buttons on the board (fig. 18), connect power to the RTC R1 electron-
ic control board until the (green) POWER LED begins flashing rapidly (fig. 18 / part. A).
Then release both buttons.
• It is now possible to electrically control the actuator by means of the UP and DOWN but-
tons.
• Press the DOWN button till the actuator can be hooked again to the lever (section 4.4 -
fig. 15 part A).
• By pressing the DOWN button, the thruster opens till the activation of the limit switch
and the STATUS LED becomes green (fig.18 part B).
If the limit switch isn't in the correct position (fig. 19A), it can be adjusted (see section 4.7).

WARNING: make sure that the constant-velocity joint is
straight, at an angle between -5° and +5° (Fig. 19B).
• By pressing the UP button, it is now possible to check the clos-
ing of the lid; once the limit switch is reached the STATUS LED
becomes red: if this closing is not enough, adjust the limit switch
(see section 4.7).
F
The thruster is already adjusted at the factory, so it
shouldn't need any closing adjustment.
