    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.

    Abstract: Un método para modernizar la función de elevación de un ascensor, en el caso de un ascensor provisto de cables de elevación (4), caracterizado porque, en conexión con la modernización, se incrementa la relación de suspensión de la cabina del ascensor y porque la suspensión (1) de los cables es provista de al menos dos poleas desviadoras (7, 12), alrededor de las cuales se monta el cable de elevación (4) para que corra de tal manera que, en la dirección de desplazamiento del cable de elevación (4), la primera polea desviadora (7) esté entre unas poleas desviadoras (6) y (8) conectadas al contrapeso (3) y, en la dirección de desplazamiento del cable de elevación (4), la segunda polea desviadora (12) este entre unas poleas desviadoras (11) y (13) conectadas a la cabina (2) del ascensor.
