ROLLS-ROYCE CE05-00 Steering Gear Control Module

ROLLS-ROYCE CE05-00 Steering Gear Control Module

Electronic unit (one per unit)

The electronic unit is designed for bulkhead mounting and should be mounted in the instrument room or

nearby the bridge. (Note! Electronic unit must not under any circumstances be removed from the

electronic cabinet and mounted into any console separately). Cable access is through a coverplate

that can be removed for fitting of cable glands. Location of the unit should be selected due emphasis on

service access.

The electronic unit contains the following: - Power supply - Application CPUs (Main and backup) including flash memory -

 CAN fieldbus - Ethernet communication with control panels   - I/O cards (DI, DO, AI, AO, serial line interfaces)

 - Circuitry monitoring w/alarm output - Indication circuitry - Cable termination

Power Supply requirement:

Main supply

Back-up supply

Power consumption:

: 230 VAC (+/- 15%) 50/60 Hz

: 24 VDC (+20% - 17%) (Battery back-up)

: Typical 100 - 200 watt

The Remote Control System is designed to accomplish prevailing rules of DNV, ABS, LRS, BV, GL and

RINA.

Distributed IO cabinet (one per unit)

The unit is designed for bulkhead mounting and should be located in the thruster room. Cable access is

through a cover plate that can be removed for fitting of cable glands. Location of the unit should be

selected with due to emphasis on service access.

The IO cabinet contains the following: - I/O to/from external connections. - Power supply - CAN field bus - Cable termination - Actuator interface Pitch

Interface to drive motor starter

The following signals are given to the drive motor starter: - Zero Pitch Signal.

A potential free relay contact for interlock start of thruster motor.

The contact is closed at zero pitch position. - Start motor.

Impulse push button for start of motor (normally open - closes for start) - Stop motor.

Impulse push button for stop of motor (normally closed - opens for stop)  - Emergency stop motor.

Impulse push button for emergency stop of motor.( normally closed – opens for stop)  - Servo pump running.

Potential free relay contact from servo pump starter, opens when servo pump stops.

The following signals are required from the drive motor starter to the control system: - Running signal

A potential free relay closing contact when the motor is running and ready for thruster operation.

Indication light on the START push button on Main Bridge Panel. - Overload signal (high temp. in windings). A potential free relay contact from the thermal relay for

overload indication in control panels.    - Drive motor current signal.

4-20mA signal from the drive motor starter.

The load control continuously monitors the power output from the drive motor and the propeller pitch

is automatically adjusted in response to the load changes detected.

DP Interface

The remote control is provided with interface for an ICON DP system.

Communication is via Ethernet.

(Other DP system will be interfaced through hardwired signals)

Signals required from the DP system: - Closing contact (potential free) to engage the DP mode. (From selector switch). - Request for control. - Pitch control signal

Signals available to the DP system: - Remote control is ready for DP - Remote control acknowledge of DP mode. - Pitch feedback signal - Power reduced signal
