摘要:
A system for controlling an elevator comprises a car door operation control system (10) for controlling movement of at least one car door (12), the car door operating control system (10) including an incremental encoder configured to provide a signal indicative of a travel distance of the car door (12) to the car door operating control system (10), and an elevator car control system (50) configured to obtain a primary Car Door Closed Signal from a car door safety switch of an elevator safety control system, said elevator car control system (50) configured to obtain a secondary Car Door Closed Signal (DFCM) independent of the primary Car Door Closed Signal based on the travel distance signal provided by the car door operation control system (10).
摘要:
A device (100) and method (300) for automatically adjusting safety control parameters of a conveyor (10, 10a) are disclosed. The safety device (100) may include various sensors (102, 102a, 104, 104a, 106, 106a, 108, 108a) and a safety control module (200, 200a). The safety control module (200, 200a) may be preprogrammed with a learn- run method (300) configured to learn operational and mechanical characteristics of a conveyor (10, 10a), validate the operational characteristics of the conveyor (10, 10a) based on predefined nominal specifications, and determine a safety function with calibrated safety control parameters by which to monitor conveyor operation.

摘要:
Automatic door systems (10, 10a) and methods capable of determining proper functionality thereof are provided. The door systems (10, 10a) are provided with a healthcheck module (22, 22a) which automatically determines functionality of the door system (10, 10a) by initially monitoring a first output signal provided by a first sensor (19, 19a) and a second output signal provided by a second sensor (18, 18a). More specifically, the healthcheck module (22, 22a) correlates the first output signal with the second output signal and operates one or more doors (12, 12a) of a door system (10, 10a) according to the correlation. The healthcheck module (22, 22a) then monitors the second output signal provided by the second sensor (18, 18a) to determine the ability of the one or more doors (12, 12a) to close, and determines functionality of the door system (10, 10a) accordingly.
