ALARM #55
UnclassifiedSensors
What This Code Means
The mode of operation at that moment will be shut down immediately; Installation is supplied with a power higher than that which has been configured; Differential switch has been activated; Operating mode has shut down; System has shut down; Inverters heat up internally; Decrease in performance; Operating mode change due to communication failure; Maximum contracted power exceeded; An error occurred in one of the inverters; System shutdown
Possible Causes
- •Maximum contracted power has been exceeded when the calendar is enabled and configured
- •Inadequate EHR input and output wiring
- •Loose wiring terminals
- •Improper ground connection
- •State of Charge (SoC) of the battery is too low
- •Communication not working properly
- •Problem in the internal core (either the Cerbo GX or the eCORE)
- •Maximum power contracted in the EHR output has been exceeded
- •Very high ambient temperature (above 30°C)
- •Very high inverter power (approaching inverter limits)
- •Communication failure
- •The maximum contracted power has been exceeded
- •Maintenance disconnector is damaged
- •Inverter is damaged
- •Inverter has stopped working
Suggested Actions
- 1Configure the calendar (refer to Calendar section)
- 2Check that the EHR’s input and output wiring is adequate and that all terminals are well threaded
- 3Check that the ground is connected as indicated in the manual and that the terminals are well threaded
- 4Reset the differential by clicking on 'reset' to reset the magnetothermal output
- 5Perform an optimal load
- 6Perform a maintenance load
- 7Perform an external load as indicated in the manual
- 8Run the operating mode again
- 9Check the RJ45 connectors inserted between the Cerbo GX and the CCLAN
- 10Perform a system shutdown without disconnecting the batteries as detailed in the manual
- 11Restart the system
- 12Decrease the load in the installation
- 13Restart the desired functionality
- 14Deal with the warning when it appears in order to prevent the temperature alarm from occurring as per the help functions shown on the screen
- 15Refer to the manual to perform a system shutdown (do not turn the batteries off)
- 16Check that the communication between the inverters is correct
- 17Check that the RJ45 connectors are in good condition and tight
- 18Check the position of the inverter disconnector causing the error
- 19Turn the batteries off and replace the disconnector to ensure the disconnector is in the correct position
- 20Restart the equipment
