The following icons, faults, descriptions and solutions will help to identify shutdown alarm icons for Commodore Water-Cooled Diesel Generators using the Deep Sea 4620 Controller
Icon | Fault | Description | Solution |
Fail To Start |
The engine has failed to start after the configured number of start attempts |
-Does it have enough fuel? -is there any present fault codes preventing the generator from starting? |
|
Low Oil Pressure |
The module detects that the engine oil pressure has fallen below the low oil pressure pre-alarm setting level after the Safety On timer has expired |
-Does the generator need a service? -Is there enough oil in the genrator? -Is the sensor plugged in properly? |
|
Engine High Temperature |
The module detects that the engine coolant temperature has exceeded the high engine temperature pre-alarm setting level after the Safety On timer has expired |
-Is the coolant level correct? -Is the radiator cap on properly? -Is the engine fan operating properly |
|
Under Speed |
The engine speed has fallen below the under speed pre alarm setting |
-Is the generator getting enough fuel? |
|
Over Speed |
The engine speed has risen above the over speed pre alarm setting |
-Is the engine rpm set correctly? | |
Charge Failure | The auxiliary charge alternator voltage is low as measured from the W/L terminal |
-Is the 12v alternator belt fitted correctly/not worn -is the battery in good condition and not drawing too much power from the 12v alternator? |
|
Low Fuel Level | The level detected by the fuel level sensor is below the low fuel level pre-set alarm setting | -Is there enough fuel in the tank? | |
High Fuel Level | The level detected by the fuel level sensor is above the high fuel level pre-set alarm setting | -Has the fuel tank been overfilled? | |
Generator Under Voltage | The generator output voltage has fallen below the pre-set alarm setting. after the Safety On timer has expired |
-Has the voltage regulator been set correctly? -Is the generator getting enough fuel? -Has the generator rpm been set correctly? |
|
Generator Over Voltage | The generator output voltage has risen above the pre-set alarm setting |
-Has the voltage regulator been set correctly? -Has the generator rpm been set correctly? |
|
Generator Under Frequency | The generator output frequency has fallen below the pre-set prealarm setting after the Safety On timer has expired. |
-Has the voltage regulator been set correctly? -Is the generator getting enough fuel? -Has the generator rpm been set correctly? |
|
Generator Over Frequency | The generator output frequency has risen above the pre-set prealarm setting. |
-Has the voltage regulator been set correctly? -Has the generator rpm been set correctly? |
|
Delayed Over Current | The measured current has risen above the configured trip level for a configured duration. | - Decrease your energy usage as you're currently right at the threshold of the generators capacity | |
kW Overload | The measured kW has risen above the configured trip level for a configured duration | - Decrease your energy usage | |
Emergency Stop | The emergency stop button has been depressed. This failsafe (normally closed to emergency stop) input and immediately stops the set should the signal be removed. |
-Has the emergency stop button been released? -If the button has been realeased is it still displaying on the screen? if it is then the switch is faulty |
|
Oil Sender Open Circuit | The oil pressure sensor has been detected as being open circuit | -Is the wiring to the sensor shorting out/have a break in the wire somewhere? | |
Oil Filter Maintenance Alarm | Maintenance due for oil filter. |
-Has the generator been serviced regulary/ on time? |
|
Air Filter Maintenance Alarm | Maintenance due for air filter | -Has the generator been serviced regulary/ on time? | |
Fuel Filter Maintenance Alarm | Maintenance due for fuel filter | -Has the generator been serviced regulary/ on time? |
