Question
Which Controller model is best for simple liquid-level detection without pump control?
Answer
Floatless Level Controller 61F-GP-N is suitable.
Prepare the same number of 61F-GP-N Controllers as the number of liquid-level detection points.
Connections:
Note:
The power supply phases (terminals 3 to 9) can be matched to use the same ground for the common Electrode (the longest Electrode, terminal 4).
Principles of Operation:
・Terminals 6 and 7, and terminals 10 and 11 on the lower -limit 61F-GP-N are shorted when the water level reaches E3 (indicator ON).
・Terminals 6 and 7, and terminals 10 and 11 on the intermediate 61F-GP-N are shorted when the water level reaches E2 (indicator ON).
・Terminals 6 and 7, and terminals 10 and 11 on the upper-limit 61F-GP-N are shorted when the water level reaches E1 (indicator ON).
