    摘要: A device and method for detecting a misaligned or missing step of a conveyor are disclosed. The missing step detector includes various sensors for detecting the drive speed of the conveyor and for detecting the presence of pallets or steps. The sensor output signals are correlated to determine fixed values characteristic of the specific conveyor in question. Using the fixed values as reference, the missing step detector is able to effectively monitor the conveyor for misaligned or missing steps independent of conveyor speed and time.

    摘要: An elevator control system includes a control power supply, a computing core in communication with the control power supply, a communication power supply in communication with the computing core, and a sleep monitor in communication with the control power supply, the computing core, and the communication power supply. The sleep monitor is disposed to selectively turn on/off the control power supply and the computing core, and the sleep monitor is disposed to selectively change an operating state of the communication power supply to a low voltage state.

    摘要: An exemplary safety circuit includes a plurality of contacts that are configured to establish a conductive path across the contacts when the contacts are in electrically conductive contact with each other. The contacts selectively interrupt the conductive path across them when the contacts are separated. A controller selectively introduces a voltage pulse across the contacts at a voltage level that is effective to overcome an electrical resistance of any contamination on at least one of the contacts. The controller introduces the voltage pulse at least when the contacts are expected to be in contact to establish the conductive path.
