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

automatically start and stop the engine.

It will indiCAT-parts-partse the operational status and fault conditions, automatically shut down the engine and indiCAT-parts-partse

the engine failure by a flashing LED on the front panel.

Other simultaneous faults are indiCAT-parts-partsed 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.

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 indiCAT-parts-partsion, warning or shutdown inputs either immediate or held off during start up.
