a) Equipment located in the Engine Room
VOYAGER Panel: This panel is the main control unit for the system and resides in an industry standard electrical enclosure, which is normally mounted in the ECR. There are two inputs and three outputs required for this unit
i) Mains electrical input (100-240V AC).
ii) A multi-core lead input from the sensors and tachometer on the turbocharger.
iv) A relay output for connection to UMS alarm system.
v) Ethernet communications output to the ships network mailbox, and for data backup.
vi) A multi core lead output for connection to the D+ satellite unit
b) Equipment located on the machinery
Sensors: The sensors are mounted externally and non-intrusively on the machines by means of adapter blocks. These adapter blocks are attached at suitable positions in the same plane as the bearings to ensure an adequate transmission path for the vibration signals. The leads from the sensors are then connected to local junction boxes and a multi-core twisted pair cable transmits the vibration signals to the main VOYAGER unit in the engine control room.
