General Motors SD and GP locomotives. The system is designed to sense the state of the MU
control lines, operator controls and various feedback and sensing devices, and provide power and
dynamic braking as required in order to maintain a pre-set speed. The display unit of this system
shows self-diagnostics, alarm data, operation of speed control and setup parameters. Locomotive
speed is monitored by the use of 120 pulse-per-revolution rotary sensors. The ECU also monitors
and regulates main generator output current and voltage.
The applicable subheading for the QES 1000 Locomotive Excitation System will be
9032.89.6085, Harmonized Tariff Schedule of the United States (HTS), which provides for other
automatic regulating or controlling instruments and apparatus, other. The rate of duty will be 3.6
