UNIC (5 Series)

Product Description

The Unic (5-series) automation system is an embedded engine management system used for Gas and Dual Fuel Engines on vessels with ACC or ACCU Class Notation. , , The UNIC system is handling all tasks related to start/stop management, engine safety, fuel management and speed/load control, as well as charge air, cooling, and combustion, and the system utilizes modern bus technologies for safe transmission of sensor- and other signals., , The system has a modular design, and some parts and functions in the UNIC configuration are optional depending on application. , , UNIC is a modular system, which consists of the following major parts:, LDU-30 - Local Display Unit: , Contains push buttons for local engine control, and a graphical display for local reading of the most important engine parameters. All sensors on the engine are connected to the UNIC system, and the information from these is , displayed on the LDU (all sensor data, but also other information such as engine modes, possible failures and an event log)., COM-10 - Communication module, ESM-20 Engine Safety Module:, Handles fundamental engine safety, and is the interface to the shutdown devices., CCM-30 Cylinder Control Module., Handles all the injection and combustion monitoring, and cylinderwise inlet valve timing control., IOM-10 Input/output Module:, Handles measurements and controls distributedly on the engine where the sensors/devices are located. The number of modules varies according to cylinder number, engine type and application., , Please see engine installation specific documentation for more info on tuning parameters, troubleshooting, and for installing software into the system.,
