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.
Main features
CONFIGURABLE INPUTS
Configurable inputs are available for:
*Low Oil Pressure
*High Engine Temperature
*Remote Start.
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.
ALARM CHANNELS
Multiple alarm channels are provided to monitor the following:
*Under/Overspeed
*Charge Fail
*Emergency Stop
*Low oil pressure
*High engine temperature
*Fail to Start
*Fail to stop
*Loss of speed sensing
*Programmable inputs as selected
First up alarm is indicated by a flashing LED. Subsequent simultaneous alarms are displayed by a steady LED.
