Relay control MAX and MIN statues set by user of controlled fluid. After the liquid level decreases to MIN (i.e. electrodes MIN and COM spaced), the MIN joint is switched to position 17-16 (FILLING), whereas the MAX joint remains in position 21-22. On the other hand, when the MAX liquid level is reached (MAX and COM electrodes shorted), the relay's MIN joint will be switched to position 17-18 (EMPTYING), whereas the MAX into position 21-20. Emergency state: ALmin (dry running) - after the liquid level decreases to ALmin (i.e. electrodes MIN and COM spaced), the ALmin joint is switched to position 12-11; ALmax (overflow) after level is reached Almax (ALmax and COM electrodes shorted), the relay's Almax joint will be switched to position 15-14. .
The electrode probe is connected by means of a cable with wire diameter up to 1mm and maximum length of 100 m.
Joints 4-5-6 -7-8 galvanic separated.
