The installation and operation manual of JK type static overflow alarm controller is suitable for flammable and explosive oil depots and gas stations, as well as liquid benzene, hydrocarbon sealed vehicles and other chemical products packaging systems.
The JK static electricity overflow alarm controller is designed for oil‑storage, fueling stations and chemical filling systems to ensure proper grounding and prevent liquid overflow. The device features explosion‑proof construction, sound‑light alarms, and relay outputs for integration with third‑party control systems.
The guide covers preparation before use, detailed installation steps, wiring diagrams, system maintenance, fault analysis, technical specifications, spare‑part lists and ordering information. It also includes safety precautions and explosion‑proof certification details. This manual is written in Chinese.
