BMS Fault

What does 106 mean?

A critical fault has been detected by the Battery Management System (BMS), indicating a severe issue with the battery or its management. This fault disables all motion functions.

• Critical fault detected by the BMS, potentially related to battery cells, temperature, or communication failure.
• Internal failure within the BMS module.
• Serious battery voltage, current, or temperature condition.

Click steps to track your progress.

1. 1

   Measure the battery voltage at the terminals of the BMS unit to confirm it is within the specified operating range.

2. 2

   Inspect all wiring and connectors between the battery, the BMS module, and the main elevator control board for loose connections, corrosion, or physical damage.

3. 3

   Verify the input supply voltage to the BMS charging circuit or the dedicated battery charger to ensure proper power delivery for battery maintenance.

4. 4

   Check the BMS diagnostic indicators or the elevator control panel's fault log for any specific sub-codes or additional information related to the BMS fault.
