Alphatronic 3000 Propulsion Control System

Product Description

The Alphatronic 3000 propulsion control system is used for remote control of a ship’s propulsion line. A two-stroke low speed engine directly connected to the propeller shaft line or a four–stroke medium speed engine is connected to a fixed pitch propeller (FPP) or controllable pitch propeller (CPP) through a reduction gearbox, with optional clutch control for the main engine clutch, power take–off (PTO) clutch to a shaft generator (SG) and the power take–in (PTI) clutch for a pony motor to start up the SG in PTI
mode (optional) used for electrical take-home power. The Alphatronic 3000 is operated by means of setpoint levers and colour graphic touch panels.
The Alphatronic 3000 is operated as an independent stand–alone system, with all information and internal alarms displayed on the graphic operator panels.
When the Alphatronic 3000 is delivered together with a MAN four–stroke engine, the PCS is interfaced with the units fitted on the engine. These units ensure local control, engine monitoring and engine safety functions.
Local control and monitoring of the propeller and possibly the gear box, is carried out from the system called Local Propulsion Control System (LPCS). For certain MAN engines, the LPCS will share the Local Operator Panel (LOP) with the engine. From the LOP, also the order telegraph can be operated.
The Alphatronic 3000 can, depending in the actual plant, provide control of:
? Main engine start/stop
? Main engine setpoint (combinator, constant rpm and separate)
? Main engine load control (load control limitations)
? Main engine load reduction (rpm and/ or load reduction)
? Combinator control from single lever in ECR and on the bridge
? Controllable pitch propeller (CPP) setpoint system (combinator curves)
? Control transfer (bridge/ECR setpoint selection)
? Propulsion mode selection (combinator, constant rpm and separate)
? Bridge wing control with wing panels and electric shaft on setpoint levers
? Alarm announcement and indication
The Alphatronic 3000 can be extended with the following options:
? Clutch control (ME, PTO and PTI (engage/ disengage)
? Propeller shaft speed measurement and indication
? Interface to PTO connected shaft generator (SG waiting station)
? Alternative propulsion (PTI mode)
? El motor operating with stopped (ME)
? Power boost (ME + PTI simultaneously)
? Speed Pilot integrated in the system
? Manoeuvring order printer integrated in the system
The remote control system constitutes the following parts:
a) Alphatronic 3000 PCU. Main cabinet with process computer and I/O modules
b) Propulsion control panels for remote control of the propulsion machinery via graphic colour touch screens
c) Setpoint levers with electric shaft ensuring bumpless transfer, also to/from ECR
d) Communication telegraph system
e) Emergency stop panels
f) External interfaces to connected systems
A combination of b), c), d) and e) will form a control station for centre bridge, bridge wings, aft bridge or ECR.
