| Measuring principle | An alternating voltage exists between the probes in an empty tank. As soon as the conductive liquid in the tank creates a connection between the ground probe and, for example, the maximum probe, a measurable current flows and the device switches. With level limit detection, the device switches back as soon as the liquid clears the maximum probe. With two-point control, the device does not switch back until the max and min probe is cleared. Using alternating voltage prevents corrosion of the probes and electrolytic destruction of the product. The material used for the tank walls is not important for measurement because the system is designed as a closed potential-free circuit between the probes and the electronics. There is absolutely no danger if the probes are touched during operation. |

| Input signal | probes covered - A measurable current is flowing between the probes. probes uncovered - There is no measurable current flowing between the probes. |
| Signal on alarm | output N1 (FEW58): output signal with damaged sensor < 1 mA |
| Fail-safe mode | Selecting the correct fail-safe mode ensures that the relay/the output always runs in quiescent current fail-safe. output E5 (FEW52): - maximum fail-safe: The output signal is < 1 mA if the switch point is exceeded (probe covered), a fault occurs or the power supply fails. - minimum fail-safe: The output signal is < 1 mA if the switch point is undershot (probe uncovered), a fault occurs or the power supply fails. Output WA (FEW54): - maximum fail-safe: The relay de-energises when the switch point is exceeded (probe covered), a fault occurs or the power supply fails. - minimum fail-safe: The relay de-energizes when the switch point is undershot (probe uncovered), a fault occurs or the power supply fails. output N1 (FEW58): - maximum fail-safe: The output voltage is 0 V if the switch point is exceeded (probe covered), a fault occurs or the power supply fails. - minimum fail-safe: The output voltage is 0 V if the switch point is undershot (probe uncovered), a fault occurs or the power supply fails. |
| Lead monitoring | For probes without an electronic insert, an additional printed circuit board must be installed in the housing, which enables cable monitoring. It is always switched or connected between rod/rope 1 and 2. Note! When using switching units (transmitters) that do not support cable monitoring, these must be removed. |
