DSE 5xxx Configuration Software ManualFunctionMains Load InhibitPanel LockRemote resetDescriptionThis input is used to prevent the 5220/5320 from loading themains supply. If the mains supply is already on load activatingthis input will cause the module to unload the mains supply.Removing the input will allow the mains to be loaded again.NOTE:-This input only operates to control the mainsswitching device if the 5220/5320 load switching logicis attempting to load the mains. It will not control themains switching device when the generator is on load.This input is used to provide security to the installation. If thePanel lock input is active, the module will not respond tooperation of the Mode select or start buttons. This allows themodule to be placed into a specific mode (such as Auto) andthen secured. The operation of the module is not affected andthe operator will still be able to view the various instrumentationpages etc. (Front panel configuration access is barred whilesystem lock is active).This input can be used to reset the module’s alarm condition,providing that the fault condition is no longer active. Themodule’s operating mode is unchanged.For instance if the module is in AUTO mode with an alarmpresent, and the fault condition itself has been cleared, thenactivating remote reset will reset the alarm, leaving the modulein AUTO mode.WARNING!: If the module is in auto mode and aremote start input is present (or in the case of5220/5320, mains is not available), the engine willrestart following a remote reset commandRemote Start on loadRemote Start off loadSimulate Mains availableIf this input is active, the 52xx/53xx will operate thus:- To usethis function the 52xx/53xx should be placed in the AUTOmode. The module will perform the start sequence as describedearlier in this manual.If this input is active operation wil be similar to the ‘RemoteStart on load’ function except that the generator wil not beinstructed to take the load. This function can be used where anengine only run is required e.g. for exercise.This function is provided to over-ride the 5220/5320 module’sinternal monitoring function. If this input is active the modulewill not respond to the state of incoming AC mains supply unlessthe monitored AC mains supply is out of limits AND this input isinactive. This can be used to control the operation of thegenerator during a mains failure by allowing generator operationonly if equipment operation requires the genset to runNOTE:- The supplied configuration file 5310NFPA.mcf/5320NFPA.mcf containssetup information for the expansion outputs, designed to operate the 549 NFPA110annunciator module in conjunction with the P130 input expansion module.For further information on the P130 and P549 modules, please see the DSE manualentitled P130 input expansion module/P549 remote annunciator Operators Manual.26DSE 5xxx Configuration software ISSUE 2 02/07/04 AM
