Two-state liquid level control relay, with sensitivity adjustment, with PZ2 probes (3pcs), 2×1P contacts, I=2×16A, 3 modules PZ-829 RC F&F
Purpose
PZ-829 relays are used to detect the presence of electrically conductive liquids at the levels of installed flood probes. They allow to maintain the minimum and maximum states of the controlled liquid within the range set by the user.
Operation
When the liquid level drops to the MIN state (i.e., MIN and COM electrodes open), the MIN contact is switched to the 11-12 position; the MAX contact remains in the 8-9 position. When the MAX state is reached (MAX and COM electrodes closed), the MIN relay contact is switched to the 11-10 position, and the MAX contact is switched to the 8-7 position.
Probe connection method
Electrode probe connected by a wire with a wire diameter of up to 1mm and a maximum length of 100m .
Note:
Terminals 4-5-6 separated from the network.
