Abstract
A safety control device (1) for a people conveyor (101) includes a first safety control channel (2) configured to output a first safety control signal in response to one or more input signals (10, 12, 14). A second safety control channel (4) is configured to output a second safety control signal in response to one or more input signals (10, 12, 14). An override control channel (6) is configured to monitor a health of the first and second safety control channels (2, 4) and determine whether a fault has occurred in either of the first or second safety control channels (2, 4). The override control channel (6) is configured to override the first or second safety control signal in response to a determination that a fault has occurred in the corresponding safety control channel (2, 4). The override prevents activation of one or more safety systems.
