Description
The C3+ can remotely control and monitor a diesel engine via the Murphy PowerCore® TEC-10 engine controller as explained in this Technical Note. The installation of the Murphy TEC-10 is not detailed in this article, this should be carried out by a qualified technician. This article focuses on the interface between the C3+ and TEC-10 Controller. Observant will provide support ONLY for the configuration of the C3+.
Remote control capability should not replace local on/off control or any other fail-safe hardware. An Emergency Stop button and appropriate power disconnects should always be in place at the same location as the Engine.
