UNIC C1

Product Description

The Unic C1 automation system is an embedded engine management system used for Diesel 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. The UNIC C1 architecture has a completely hardwired signal interface with external systems., , 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:, ESM-20 Engine Safety Module. Handles fundamental engine safety, and is the interface to the shutdown devices., MCM-11 Main Control Module. Handles all strategic control functions (such as start/stop sequencing and speed/load control) of the engine., PDM-10 Power Distribution Module handles fusing, power distribution, earth fault monitoring and EMC filtration in the system. It provides two fully redundant supplies to all modules., , See UNIC C1 System Description Wartsila Auxpac 20 documentation for more info on tuning parameters, troubleshooting, and for installing software into the system.
