Appendix E. Controller Displays from the Engine ECM
The controller display showing engine information is dependent upon the engine manufacturer and the corresponding Engine
Control Module (ECM). The following list indicates which engine displays are available by the engine manufacturer. This
information is subject to change by the engine manufacturer.
Note:
See the generator set specification sheet for engine model identification.
Some engines do not have an ECM and in some cases the ECM information is not available as a controller display. In these
situations, critical information like oil pressure and coolant temperature are displayed by the controller using independent engine
sensors not used by the ECM.
