一級開關(guān)信號用于報警，如果將此信號與跑調(diào)整裝置相接，即可實現(xiàn)不停機狀態(tài)下的跑偏自動調(diào)整。 
二級開關(guān)信號用于停機，將此信號接至控制線路中，即可實現(xiàn)重度跑偏狀態(tài)下的自動停機。
當(dāng)故障排除后，膠帶離開立輥正常運轉(zhuǎn)時，立輥可自動復(fù)位。 
為了適應(yīng)戶外條件下長期使用，本產(chǎn)品均采用整體密封，內(nèi)部金屬零件進行鍍鋅純化處理，外部零件除殼體外均做多層光亮鍍鉻，殼體為鑄鋁/不銹鋼制造，表面采用靜電噴涂技術(shù)處理，適宜在惡劣環(huán)境下使用。

適用范圍

雙向拉繩開關(guān)和兩級跑偏開關(guān)用于常規(guī)皮帶輸送機：地下、索道支撐皮帶輸送機：輪船裝卸系統(tǒng)；堆垛/取料輸送機；傾斜和梭式輸送機；起重機、挖掘機，起重臂限位：裙邊給料機/輸送機：重型極限開關(guān)檢測膠帶的跑偏量，是實現(xiàn)膠帶機控制的自動報警和停機的保護裝置。
