ALARM #1
What This Code Means
Battery state of charge (SoC) is low (less than 20%); Equipment has been turned off; Master phase has been deactivated; Immediate system shutdown; Machine shuts down suddenly; System loses communication with one of the inverters (L1, L2, or L3); Immediate shutdown occurs; System issues an alarm; Operating mode shuts down; Alarm runs continuously; High inverter temperature warning occurs; Output overload warning occurs; System shuts the operating mode down; Error LEDs are on (red); Battery error persists after restarting; Battery state of charge is low (30%, 25%, or 21%); Operating mode will shut down when battery charge reaches 20%; The equipment has shut down; One of the devices assumed the master state; Firmware incompatibility; Equipment shutdown; Operating mode change due to communication failure; Maximum contracted power exceeded; An error occurred in one of the inverters
Possible Causes
- •Battery energy is depleted
- •Emergency mushroom is pressed
- •Unsafe condition (such as a very high overload)
- •System security reasons
- •Repeated shutdown of the equipment
- •False contacts in the DC distribution of the inverter (due to the battery switch or incorrect tightening torques on the terminals)
- •Poor connection of communication cables between the inverters and the L1 inverter to the Cerbo GX (due to a worn or broken RJ45 connector)
- •Inverter is defective and has stopped working due to internal causes
- •One of the phases has been turned off
- •One of the inverters turned off during its operation
- •Erroneous synchronization between the inverters
- •Failure of real-time communications
- •High inverter temperature
- •Output overload
- •BMS of the batteries detects that a battery cell has a voltage lower than acceptable
- •Defective battery
- •Deterioration of battery cells
- •Problem in communication in battery modules
- •Low battery state of charge
- •One of the phases has been disabled
Suggested Actions
- 1Prompt loading (charging) of the batteries
- 2Perform battery maintenance
- 3Disengage the emergency mushroom
- 4Reset the system
- 5Refer to the on-screen help
- 6See 7.Warning and Alarms
- 7Perform a complete restart of the EHR equipment
- 8Refer to the steps indicated in the on-screen help
- 9See 5. Starting up the EHR plant
- 10Deal with the warning by referring to the on-screen help
- 11Refer to 7.Warning and Alarms
- 12Check that the batteries are working properly
- 13Identify which battery is defective
- 14Turn the batteries off and restart the equipment
- 15Charge the battery as soon as possible
- 16Refer to the manual to perform a system shutdown (do not turn the batteries off)
- 17Check that the communication between the inverters is correct
- 18Check that the RJ45 connectors are in good condition and tight
- 19Check the position of the inverter disconnector causing the error
- 20Turn the batteries off and replace the disconnector to ensure the disconnector is in the correct position
