SV 150/250: Relay control of DISCHARGING SV 160/260: Relay control of CHARGING Example 1 The diagram shows the level control connected as max. and min. control, i.e. registration of 2 levels during charging (discharging). The relay releases (operates) when the max. sensor is in contact with the substance, provided that the min. sensor is immersed. The relay operates (releases) when the min. sensor is no longer in contact with the substance. of 1 level during charging (discharging). The relay releases (operates) when the sensor is in contact with the substance.
