Threshold switch KRS-E08 HRP-The threshold switch is used for switching units, pumps, fans, burners, electric heaters, etc. An analogue control signal of 0 ... 10 V DC can be used for control. As soon as the input voltage reaches the switching threshold in "Auto" operating mode, the relay switches on.-If the input voltage falls below the switch-off threshold, the relay switches off again. A manual operating level with feedback is integrated for servicing. The module can be controlled in two ways, which can be set using the integrated three-stage switch (Auto, 0, 1). The switch-on threshold and the hysteresis can each be set using a rotary control. 1. Switch position "1": The output relay is controlled via terminals A1 and A2. 2. Switch position "0": The relay is in the idle position (11-12 bridged) 3. switch position "Auto": The output relay is controlled via the voltage at input YR. The operating voltage must be
