Control System DSE3110

All MPMC series genset have a control cubicle (the deepsea controller DSE3110 as standard) mounted on a isolated support, which has the following features:
1.Electronic digital control module with monitoring/control facility and warning indicators;
2.Automatic shutdown protection;
3.Emergency stop button (lock-down type);
4.AC output circuit breaker with over-current protection;
5.DC circuit control switch.
The control module gives digital readouts of:
1. Generator voltage;
2. Output frequency;
3. Engine speed;
4. Battery voltage;
5. Engine hours run.
Note:
1. The engine coolant temperature used temperature meter display;
2. The engine oil pressure used oil pressure meter display;
3. Generator current used current meter display and used change switch for each phase displayed separately
The control module has indicators for failure information:
1. Overspeed/underspeed,
2. Emergency stop
3. Low oil pressure;
4. High water temperature
5. Failure to start
6. Battery charger failure
Automatic shutdown occurs under:
1. Low engine oil pressure;
2. High engine water temperature;
3. Overspeed/underspeed;
Failure to start after three attempts.
The controller option:
