ALARM #52
UnclassifiedCooling
What This Code Means
Differential switch has been activated; Operating mode has shut down; System has shut down; Excessive discharge of the battery; Error LEDs are on (red); System temperature below desired level; System stopped via emergency mushroom; The differential switch has been activated; Internal battery cells are unbalanced; Active alarm (e.g., Low charges); Emergency mushroom is pressed; Differential switch of the running EHR equipment trips; Magnetothermal output tripped; Operating mode shuts down for safety reasons; Equipment shutdown; Inverters heat up internally; Decrease in performance
Possible Causes
- •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
- •Battery is defective
- •One or more cells of the batteries are defective
- •Heaters inactive
- •The emergency mushroom has been pressed
- •Inadequate input and output wiring
- •Terminals not well threaded
- •Battery cells are out of balance
- •Pressing of the emergency mushroom (potentially due to a safety condition)
- •Current drift at the output
- •Current drift in the installation feeding the EHR
- •State of charge (SoC) of the batteries has decreased by 20% during operation
- •Primary power supply cannot be activated remotely
- •Primary power supply is supplying the installation at its maximum power, preventing battery charging
Suggested Actions
- 1Check that the EHR’s input and output wiring is adequate and that all terminals are well threaded
- 2Check that the ground is connected as indicated in the manual and that the terminals are well threaded
- 3Reset the differential by clicking on 'reset' to reset the magnetothermal output
- 4Perform an optimal load
- 5Perform a maintenance load
- 6Perform an external load as indicated in the manual
- 7Run the operating mode again
- 8Check the RJ45 connectors inserted between the Cerbo GX and the CCLAN
- 9Perform a system shutdown without disconnecting the batteries as detailed in the manual
- 10Restart the system
- 11Decrease the load in the installation
- 12Restart the desired functionality
- 13Perform a system shutdown according to the manual (do not turn the batteries off)
- 14Check that the batteries are working properly
- 15Check to see if the error LEDs are on (red) and identify the defective elements
- 16Check that the communication between the BMS of the batteries and the Cerbo GX is correct
- 17Check that the RJ45 connectors connected between the battery modules are in good condition and tightly tightened
- 18Turn the batteries off and restart the equipment
- 19Charge the batteries by applying an operating mode and performing a maintenance charge
- 20Replace faulty modules if the error persists
