Dual-mode liquid level control relay with sensitivity adjustment PZ-832 RC F&F

Operation
The relay maintains the level of the controlled liquid within the range of the designated minimum and maximum states. When the liquid level drops to the MIN state (MIN and COM electrodes open), the MIN contact is switched to the 17-16 position (FILLING operation), and the MAX contact remains in the 21-22 position. When the MAX state is reached (MAX and COM electrodes closed), the MIN relay contact is switched to the 17-18 position (DRAINING operation), and the MAX contact is switched to the 21-20 position. Alarm condition: ALMIN (DRY condition) - when the liquid level drops to the ALMIN level (ALMIN and COM electrodes open), the ALMIN contact will be switched to the 12-11 position; ALMAX (overfill condition) - when the ALMAX condition is reached (ALMAX and COM electrodes shorted), the ALMAX relay contact is switched to the 15-14 position. Each of the states, i.e. the corresponding level probe shorted to the COM probe, is indicated by the lighting of the corresponding LED on the relay face. The illumination of the yellow MIN LED indicates the FILL operation state.

Probe connection method
Electrode probe connected by a wire with a conductor diameter of up to 1 mm² and a maximum length of 100 m .

Note:
Terminals 4-5-6-7-8 are separated from the mains.
