Control System——Deep Sea 6120 Controller

① Power switch

② Power indicator

③ Run button

④ LCD display

⑤ Emergency stop button

It is a self-starting control module at mains failure and is suitable for controlling a single genset. It provides advanced engine testing and protection functions. This module includes an LCD backlit display that clearly displays the engine running status. The module also includes 7-channel input and 6-channel output. Program can be set through the panel and PC software suite.


Deepsea 6120 controller provides such parameters as generator frequency, idling/overspeed, generator voltage, generator current, engine oil pressure, engine water temperature, flexible fuel level, running hour, battery voltage, start/stop failure, emergency stop, failure to meet operating voltage/frequency, charging failure, magnetic sensor signal loss, low battery voltage, three-phase mains voltage and mains frequency.


Protective functions:

◆ High water temperature

◆ Low oil pressure

◆ High/low voltage
