Request Information
The Model 501NK-1 is an Engine Protection Module, which has been designed to control the engine via an externally fitted switch provided by the OEM. The module is used to protect the engine, indicating fault conditions; automatically shutting down the engine and indicating the engine failure by LED giving true first up fault annunciation.

Operation of the module is via a terminal providing a ‘RUN' input, which also powers the module. The OEM must provide suitable arrangements for starter operation externally, such as a push-button or keys-witch position. If the ‘Run' input is de-energised the DC supply is removed from the module and the run relay and alarm output are de-energised. If the ‘Run' input is energised, the module is powered up and the run relay is energised, activating the engine fuel/ignition system and the protection hold-off timer is initiated. The external starter circuit should then be operated. Once the engine has started the external starter circuit should be de-energised.
