6 Functions
This chapter describes how to adjust parameter settings for some of the functions of the
remote control system.
Please be aware of that the described adjustments are already carried out by qualified
Rolls-Royce personnel at the commissioning and the sea trial period, and normally not
need to be changed. However, if transmitters or other devices are replaced it may be
necessary to re-adjust the current device.
6.1 Levers
When a lever has been replaced the operator device has to be re-calibrated. When
calibrating a lever the current thruster should not be running. All calibration is done
using the CDP tool described in the previous chapter. Calibration must be done for both
the Normal controller and the corresponding Backup controller.
There are at the most three lever functions available for calibration, depending on the
functions available for the current thruster. This is Pitch control, Rpm control and
Azimuth control. If the thruster have both Pitch and Rpm control but is operated only
through a common Pitch/Rpm lever, calibration of the Rpm control lever will not be
necessary. The thruster is then operating through combinator curves and the only
calibration necessary is calibration of the Pitch control lever.
6.1.1 Pitch Control Lever
A Pitch control lever has three adjustments available; Astern, Neutral and Ahead
position, with respective range adjustments.
