Abstract: The invention relates to an elevator having a safety controller (10) to which several safety switch arrangements (20-28) are connected, which safety controller is configured to cause the stop of the elevator motor (14) and the activation of the motor brakes (16), in the safety controller (10) a comparator (32) is provided for the determination of the status of the safety chain, which comparator is connected with a memory (34) for storing at least one resistor reference value, which comparator is configured to output a safety chain status signal in dependence of comparison of a measured resistance value with the resistor reference value. Each of said safety switch arrangements comprises at least one first resistor (38) and a safety switch (36) which are connected in series, the value of the first resistor (38) is different in at least some safety switch arrangements (20-28), preferably in all safety switch arrangements, and each safety switch arrangement (20-28) comprises at least a second resistor (40) connected in parallel with the safety switch (36), which second resistor has a higher value than the first resistor (38). The invention allows the detection of a short circuit as well as of the opening of a safety switch arrangement.
