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).
