Load test. No longer resistors grid submerged in water bath needed to perform
this test.
EMD EM-2000 Microprocessor. EMD offers retrofit kit for older locomotives, too.
Siemens SIBAS-16 Microprocessor. With introduction of SD70ACe, EMD terminated
contract with Siemens and Mitsubishi became partner. All functions of SIBAS-16
were relegated to EM-2000 microprocessor. This way, EMD ensured that it is not
going the ALCO way. ALCO manufactured early locos for GE and procured electrical
components from GE, even after GE started manufacturing her own locos.
The warning "Danger" has a real meaning. GTO Traction Control Cabinet
(TCC) is housed inside. New models with IGBT have only one cabinet and require
less cooling. That creates free space for additional equipment such as Head End
Power (HEP) module, if added in future.
The Traction Control Cabinet (TCC) contains the traction inverter with control computer and is the three-phase AC
power supply for the traction motors of one locomotive truck.
