控制开关动作反向或不动作
Switch reverse action or no action |
检查接线,接点是否接反
View on wiring to see if exists wrong wiring |
控制开关有液流时动作,但无液流时不能回复Switch acts when liquid flows but does not reset when no liquid flows |
在垂直管道上,确保液流向上及外壳箭头指向向上Ensure liquid upwards and arrow on enclosure upwards on the vertical line |
流量增加时开关不动作
When flow increasing, switch does not act |
