ABSTRACT:
An elevator (49) includes remote elevator monitoring equipment (50) (REM) connected by a communication linkage (52) to a central elevator monitoring and control station (51). Main, drive, and door controllers (56-58) are interconnected (5961) with the REM. Power-on-reset (POR) of controllers is caused internally (150) or by remotely-operable relays (63-65). An elevator expert at the remote station may order a POR (108), disable components (120), try various fixes (124), and/or order maintenance (115, 135) with instructions. In another embodiment, the controller (56a, 56b) includes elevator diagnostics (150) which can recognize an elevator malfunction and either cause a relay (63) to interrupt power for an interval or cause a reboot.
