Model 501NK-1 Engine Protection Module
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.
