Can you explain the wiring for combining 61F-G Floatless Level Controllers with an upper-limit float switch and a lower-limit float switch in order to control upper and lower limits?


Connect the upper-limit float switch (SPST-NO output) between the E1 and E3 terminals of 61F-G, and connect the lower-limit float switch (SPST-NO output) between the E2 and E3 terminals of 61F-G.


However, because only about 1 mA flows between 61F electrodes at 8 VAC, be sure to use microload contacts.

Applicable model: 61F-G
