Deep Sea Electronics PLC The Model 501K-1 is a Manual Engine Control Module, which has been designed to manually control the engine via a key switch on t front panel.The module is used to start and stop 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 three position key switch mounted on the front panel with STOP(O), RUN(I) and START(II)positions.In the‘O’position the DC supply is removed from the module and the run relay and alarm output are de-energised.If the switch is turned to the‘I’position 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.If the switch is moved to the‘II position and held against the spring return, a positive supply is applied to the relevant output terminal and on to the starter motor.Once the engine has started the switch should be released and allowed to return to the‘I’position. Operation of any of the following alarms; Low Oil Pressure, High Engine Temperature, Auxiliary Shutdown, Overspeed (Optional), will cause the run relay to de-energise.This will remove the fuel/ignition supply from the engine and bring it to rest.The alarm output will be activated giving a positive DC output. Each alarm channel has it’s own LED indicator and once activated no further alarm conditions will be accepted.?The alarm output and relevant LED will remain active until the unit is reset by turning the switch to the‘O position.Dimensions: 72 X 72 X 118.5 (Excluding Key-switch) 

Deep Sea Electronics PLC The Model 520 is an Automatic Engine Control Module 

designed to automatically start and stop the engine. It will indicate the operational status and fault conditions, automatically shut down the engine and indicate the engine failure by a flashing LED on the front panel. Other simultaneous faults are indicated by steady LED.Selected operational sequences, timers and alarms can be altered by the customer by using a PC and the 808 interface and software. This also provides the operator with ‘real-time’ diagnostic facilities to monitor the operation of the system either locally or remotely. Remote PC-controlled engine starting and stopping is also featured.Operation of the module is via a three position rotary switch (key-switch option available) mounted on the front panel with STOP, AUTO and MANUAL positions. This allows the module to function with normally open or normally closed switches. Four fully configurable auxiliary inputs are provided to give protection expansion. These can be selected to be indication, warning or shutdown inputs either immediate or held off during start up.
