This Rolls-Royce Aquapilot AzT US255 CP service manual gives marine engineers, electrical technicians and vessel maintenance crews the complete documentation needed to keep the Aquapilot control system operating correctly. It covers the full system architecture — from the Aquapilot control head (AQP) on the bridge, through the Bridge Interface Unit (BIU), down to the Azimuth Thruster Control Unit (ACU) in the thruster room — including the CANopen fieldbus, CANMAN process blocks, steering feedback, pitch feedback, load control, and thrust direction indication. Because the Aquapilot system integrates steering, pitch and RPM control with the vessel’s autopilot, dynamic positioning and alarm systems, having the correct wiring, tuning and alarm data at hand is essential for safe and efficient operation.

Alarms and Diagnostics

The manual includes a detailed description of alarm points — SLIO unit failures, steering angle sensor failures, pitch feed-back failures, RPM command failures, clutch command failures, supply voltage high/low, circuit breaker trips, load measurement failures, panel failures and more. Each alarm entry identifies where the fault is detected, the operational capability that is affected, and how to clear the alarm. This makes the manual a practical tool for fault-finding on the Aquapilot system, whether the vessel is in port or at sea.

Tuning and Settings

For commissioning and re-calibration, the manual provides detailed tuning instructions for AZT1 and AZT2, covering SLIO units, converters UG1, UG11 and UG15, Aquapilot tuning, autopilot tuning, dimmer tuning, steering control, thrust control, data recorder settings, local control, steering feedback, pitch feedback, PM load curve, PM load measurement, pitch and RPM combinator settings. The tuning tables for PWM-CWMIN, PWM-CWMAX and PWM-CCWMIN/CCWMAX give the technician the exact X-Y pairs needed to restore correct steering speeds after component replacement.

Thrust Direction and RPM Indication

The TDI-21 and TDI-A1 thrust direction indicators are covered in detail — including configuration switch settings, scaling adjustments, error codes (E01, E02, E03), dimmer control, wiring connections and troubleshooting. The manual also covers the TDI-A1 analogue indicator, its R/I converter, F/U converter and SIN-COS potentiometer, plus zero-angle setting for the azimuth thruster feedback transmitter and the pitch angle transmitter.

Maintenance and Storage

For long-term reliability, the manual includes maintenance programmes for the control system and the Aquapilot control lever, general electrical specifications, cabling instructions, storage instructions for the propulsion unit and electric motors, and guidance on product disposal and scrapping. These sections help vessel operators plan service intervals and protect equipment during lay-up or shipyard periods.

Part Lists and Drawings

The final part lists identify the components used in the TDI control stations, thrust direction indicator TDI-21, back-up control panel BCP, azimuth thruster mode panel AMP, azimuth thruster control panel ACP, and the CANopen/HHT connection box X15-1. These lists are useful when ordering replacement parts or verifying delivered equipment.

Why This Manual Matters

The Aquapilot control system is a digital follow-up control system for turning and pitch angle control of the azimuth thruster propeller. When a fault occurs — a steering response failure, a pitch command failure, an overload alarm, or a bus failure — the technician needs the correct alarm description, the correct tuning procedure, and the correct wiring diagram to restore operation safely. Without the proper service documentation, troubleshooting becomes guesswork, and incorrect adjustments can cause loss of control, damage to the thruster, or unsafe vessel handling.

This Rolls-Royce Aquapilot AzT US255 CP Control System Service Manual 514-S433 provides all of that in a single PDF. It is the same document used by Rolls-Royce service engineers when commissioning, tuning and repairing the Aquapilot system on these thrusters. Whether you are maintaining a vessel with AzT US 255 CP thrusters, carrying out a refit, or preparing for a classification survey, this manual gives you the procedures, settings and specifications needed to do the job correctly.
