Abstract
A diagnostic display system for indicating the status of elevator system operating conditions develops signals representing each operating condition and detects when a car is delayed in responding to a request for service. Signals representing each operating condition are stored when a delayed car response is detected so that the status of the operating conditions as they were at the time of delayed car response can be displayed at a later time.
