SEQUENCE CONNECTOR ASSEMBLY

摘要

A sequence connector used during the testing of a control package attached to a transit car. The connector includes a display which indicates power modes in the control package which are requested by a master controller in the cab of the transit car. By comparing the power mode indicated by the connector with the functioning of the control package, the operation of the control package may be tested. The connector includes a lock-out device which prevents the transit car from being powered if the connector is inadvertently left attached to the control package.
