描述

OH1和OH3實質(zhì)為同一信號，是CPU隨機檢測的，OH1(檢測底板部位)與OH3(檢測主板部位)模擬信號串聯(lián)在一起后再送給CPU，而CPU隨機報其中任一故障。出現(xiàn)“OH1”報警時，首先應(yīng)檢查環(huán)境溫度是否過高，冷卻風(fēng)扇是否工作正常，其次是檢查散熱片是否堵塞(食品加工和紡織場合會出現(xiàn)此類報警)。若在恒壓供水場合且采用模擬量給定時，一般在使用800Ω電位器時容易出現(xiàn)此故障給定電位器的容量不能過小，不能小于1kΩ;電位器的活動端接錯也會出現(xiàn)此報警。若大容量變頻器(30G11以上)的220V風(fēng)扇不轉(zhuǎn)時，肯定會出現(xiàn)過熱報警，此時可檢查電源板上的保險管FUS2(600V，2A)是否損壞。

產(chǎn)品廣泛應(yīng)用于：電力、石油、礦井提升、港口、供熱、燃氣、供水、污水處理、冶金、造紙、紡織、化工、水利等現(xiàn)代化工業(yè)領(lǐng)域！
