This manual provides system overview, safety guidelines, installation steps, configuration, maintenance, fault analysis and technical data for the ABB…
The ABB TVOC-2 arc flash monitoring system quickly detects arc faults using an optical sensor and can trigger circuit‑breaker trip within milliseconds. It consists of an arc flash monitor, optical sensor, optional current‑sensing unit, HMI, DIP switches and various connectors.
The installation and maintenance manual covers system introduction, safety requirements, functional description, step‑by‑step installation, configuration, maintenance procedures, fault analysis, HMI operation, technical data, dimensions and ordering information. This manual is written in Chinese.

The TVOC‑2 is designed and certified according to IEC 61508 SIL 2, IEC/EN 60947‑1, IEC/EN 60947‑5‑1, IEC/EN 61010‑1, IEC 61000‑6‑2, IEC 61000‑6‑4, IEC 61326‑1, IEC 61326‑3‑1 and IEC TS 61000‑6‑5.
The power must be completely disconnected before any connection or work is performed to avoid lethal electric shock.
DIP switches activate the current‑sensing unit (CSU), enable auto‑reset and distribute the trip contacts; changing them can alter system behavior.
Because light intensity can decrease over time, a manual diagnostic test is recommended at least once a year.
