Event message:
High Flammable Gas Concentration
Explanation:
The system has detected that the concentration of flammable gases (e.g., hydrogen, methane) in the vicinity of the system exceeds the safety limit and therefore there is a danger of explosion. The system immediately entered an error state and automatically activated the exhaust fan for forced ventilation to reduce the concentration and ensure safety.
Corrective measures:
The system automatically activated the ventilation system. Do not switch the device off immediately and do not restart it. Protective clothing must be worn when entering the site, the source of the flammable gas leak must be located, and immediate action must be taken.
Continue ventilation and ensure that the concentration of flammable gas remains constantly below the safety alarm threshold. We recommend that this is checked with a portable gas detector.
After ensuring that the leak has been eliminated and the environment is safe, you must manually perform the Clear Error operation in the interface of the battery pack control system to return the system to normal operation.
