ALARM #53
UnclassifiedElectrical
What This Code Means
Differential switch has been activated; Operating mode has shut down; System has shut down; 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 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
- •One of the phases has been disabled
- •Very high ambient temperature (above 30°C)
- •Very high inverter power (approaching inverter limits)
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
- 13Discharge the batteries a little until the alarm is resolved
- 14Perform a maintenance charge to balance the internal battery cells
- 15Check the condition of the machine
- 16Verify with the operator who pressed the emergency mushroom before resetting
- 17Rearm the emergency mushroom
- 18Check all wiring
- 19Check the tightening torque of the terminals
- 20Check the installation feeding the EHR
