Engine Monitoring Unit The EMU-1 digitises analogue engine sensors Benefits • o need to change an N enabling the sharing of engine data existing engine • asy installation E throughout the NMEA 2000® bus. The Actisense EMU-1 is a specialised analogue to NMEA 2000® Gateway which converts data from analogue engine senders into NMEA 2000®, enabling all NMEA 2000® display devices to monitor the connected engine(s) on a vessel. Each EMU-1 can be configured to suit the engine it is working with, offering a flexible solution for multiple engine makes and models. Capable of reading a wide range of engine parameters, the EMU-1 will report how the engine is operating and share the information across the network. each engine has three (or less) gauges that require monitoring. Where dual engines have more than three gauges each to monitor, multiple EMU-1 units are required. The EMU-1 can be used to monitor fluid levels in up to six tanks with the addition of a configurable ‘instance’ for each tank allows the user to identify which tank the data is coming from. The EMU-1 has a PC based configuration tool that allows the settings inside the EMU-1 to be changed to best suit the engine it is working with. The EMU-1 can monitor two engines where • asy to configure to suit the E connected engine • onnect signals from fluid level C gauges (that share a common ground with the engine) to NMEA 2000® Features: nables analogue signals to E be converted to NMEA 2000® messages onvert signals from two C engines (that share a common ground) with a single EMU-1 ix gauge/parameter inputs S Four alarm inputs wo additional auxiliary inputs T ustomised case C wo Tach inputs T ide power compatibility W of 9 to 40 Vdc ulkhead mount, with optional B DIN rail mount kit otal engine hours are logged T by the monitoring of engine Tach (RPM) input Active Research Limited is registered in England, Company number: 3295909.
