Generator Controller Unit 501K Auto Start Control Pannel DSE501K Diesel Brushless Electronic Board Genset Part Replace

Electronic Engine ControlController 501K,The Model501K-1 is a Manual Engine Control Module,Key Start Module: 501K, 701...Control Modules are provided as follows:1) Key Start Module: 501K, 701, 702;2) Auto StartModule: 5110, 5210;3) Auto/ AMF Start Module: 5120, 5220, 704The Model 501K-1 is a Manual Engine Control Module, which hasbeen designed to manually control the engine via a key switch on The frontpanel. The module is used to start and stop the engine, indicating faultconditions; automatically shutting down the engine and indicating the enginefailure by LED giving true first up fault annunciation. Operation ofthe module is via a three position key switch mounted on the front panel withSTOP(O), RUN(I) and START(II) positions. In the 'O' position the supply isremoved from the module and the run relay and alarm output are de-energised. Ifthe switch is turned to the 'I' position the module is powered up and the runrelay is energised, activating the engine fuel/ignition system and theprotection hold-off timer is initiated. If the switch is moved to the 'II'position and held against the spring , a positive supply is applied to therelevant output terminal and on to the starter motor. Once the engine hasstarted the switch should be released and allowed to to the 'I' position.Operation of any of the following alarms; Low Oil Pressure, High EngineTemperature, Auxiliary Shutdown, Overspeed (Optional), will cause the run relayto de-energise.This will remove the fuel/ignition supply from he engine andbring it to rest. The alarm output will be activated giving a positive output.Each alarm channel has it's own LED indicator and onceactivated no further alarm conditions will be accepted. The alarm output andrelevant LED will remain active until the unit is reset by turning the switch tothe 'O' position.Overspeed Protection (Optional) is achieved by thefitment of an additional PCB in the module. This provides integral overspeedprotection derived from either the generator HZ output or the engine magneticpick-up (specified on ordering). The overspeed circuit monitorsthe engine speed and will shut down the engine immediately if a pre-set speedlevel is exceeded. This trip level is adjustable from 90% to 130% of fullrated speed and is suitable of both 50Hz or 60Hz systems.During enginecranking and for a short time afterwards the protection hold-off timer is activeand the relevant alarms inputs are inhibited. This enables the engine to startand achieve normal running conditions. Once the timer has expired the inputsare enabled providing normal protection from the module.Charge Failurewarning is also provided by monitoring the WL terminal on the charge alternator.This operates on a similar principal to the warning lamp fitted in a motorvehicle, should the output fail the charge fail LED will illuminate. The modulewill also provide the alternator excitation current via this connection.2) SPECIFICATION:A. Supply----9~33V continuous.B. Alternator Input Range----15~305V AC RMSC.
