description An electronic test node (1) for a safety chain (22) in a passenger conveyor system comprises an electrical connection (2) for an associated safety switch (4). A processor (6) is configured to monitor a signal carried by the electrical connection (2) so as to detect whether the associated safety switch (4) is open or closed. The electronic test node (1) further comprises a test switch (8) connected in series with the electrical connection (2), wherein the processor (6) is configured to run a test by selectively opening the test switch (8) and monitoring for a change in the signal carried by the electrical connection (2). 一种用于乘客运输设备系统中的安全链(22)的电子测试节点(1)包括用于相关联的安全开关(4)的电连接(2)。处理器(6)被配置成监测所述电连接(2)携带的信号以便检测所述相关联的安全开关(4)是断开还是闭合。所述电子测试节点(1)进一步包括与所述电连接(2)串联连接的测试开关(8),其中所述处理器(6)被配置成通过选择性地断开所述测试开关(8)并监测所述电连接(2)携带的信号中的变化来运行测试。
