Description The Kongsberg Maritime Watch Bridge Unit LCD Version (WBU/ LCD), is a unit required to run an unmanned engine room. Its main functions are to indicate engine room alarms on the bridge, to indicate and accept the transfer of machine watch responsibility to and from the bridge. For alarm presentation, the WBU/ LCD is equipped with a Liquid Crystal Display in addition to 4 group-alarm lamps. Each WBU/LCD is capable of displaying 4 lines by 40 characters. The information displayed is arranged into selectable pages: Alarm Summary,

Points Summary and Date & Time. The system will automatically switch to Alarm Summary at an alarm event. The alarms can be grouped according to the customer’s specification. A separate section of the panel is used for selecting and accepting the machinery watch responsibility (Bridge, ECR, On-duty Engineer) and for direct calling of the duty engineer on watch. The WBU communicates with the main computer unit in the K-Chief alarm system using a high speed communication network (CAN). A redundant solution with automatic changeover to another main computer unit in case of failure can be provided.Functions • Alarm group indicators. • Repeat alarm indicator. • Indicating and accepting the transfer of machine watch responsibility to/from the bridge.
