Abstract
An elevator () includes remote elevator monitoring equipment () connected by a communication linkage () to a central elevator monitoring and control station (). Main, drive, and door controllers (-) are interconnected (-) with the monitor lines. Power-on-reset (POR) of controllers may be caused internally or by remotely-operable power relays (-) which interrupt power to the controllers. Maintenance personnel at the remote station () may order a POR through the communication linkage. In another embodiment, the remote elevator monitor () determines presence of a malfunction which a POR may cure and causes a POR internally or by a power relay. In another embodiment, the controller () includes, in its program routines, elevator diagnostics () which can recognize an elevator malfunction which a POR may cure, and either cause the relay to interrupt power for an interval or cause an internal POR.
