An elevator ( 9 ) includes remote elevator monitoring equipment ( 10 ) connected by a communication linkage ( 12 ) to a central elevator monitoring and control station ( 11 ). Main, drive, and door controllers ( 16 - 18 ) are interconnected ( 19 - 21 ) with the monitor lines. Power-on-reset (POR) of controllers may be caused internally or by remotely-operable power relays ( 23 - 25 ) which interrupt power to the controllers. Maintenance personnel at the remote station ( 11 ) may order a POR through the communication linkage. In another embodiment, the remote elevator monitor ( 10 ) 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 ( 16 a) includes, in its program routines, elevator diagnostics ( 50 ) 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.
