Abstract: The invention concerns a method and a system for ensuring the operation of the safety circuit of an elevator or escalator, said safety circuit containing safety contacts ( 10, 12, 14 ) connected in series with a contactor ( 16 ). In the method, the largest bypass current coming to the contactor in a fault situation is defined, a testing device ( 202 ) is connected in series with the safety circuit, said testing device containing at least one resistor ( 26 ), which is used to produce a desired test current that is larger than the largest bypass current, and the neutral point ( 18 ) of the safety circuit is shifted if the contactor ( 16 ) remains energized by the aforesaid test current.

Abstract: Un método para garantizar el funcionamiento de un circuito de seguridad de un ascensor o de una escalera mecánica, cuyo circuito de seguridad contiene contactos de seguridad (10,12,14) y una placa de vigilancia (106), estando los contactos de seguridad (10,12,14) conectados en serie con un contactor (16), estando el contactor (16) y la placa de vigilancia (106) conectados a un punto neutro común (18), caracterizado porque el método comprende los pasos de: definir la corriente de derivación más alta que llega al contactor (16) en una situación de fallo; conectar un dispositivo de comprobación (202) en serie con el circuito de seguridad, conteniendo dicho dispositivo de comprobación al menos una resistencia (26) que se utiliza para generar una corriente de prueba deseada que es mayor que la corriente de derivación más alta; y desplazar el punto neutro (18) del circuito de seguridad si el contactor (16) sigue activado por la antes mencionada corriente de prueba.
