ELECTRICAL CONTROL

CABINETS

As mentioned in Chapter 1, MAS 696 AC AC Traction System comprises of
four Cabinets, viz. ECC#1, ECC#2, ECC#3 and TCC. The three Electrical
Control Cabinets are explained in detail in the following sections:

5.1 ECC#1

The Electrical Control Cabinet, as shown in Fig. 5.1, is located in the drivers
cab. It houses equipments that controls and supplies power to the
Locomotive.

The various internal equipments (not driver
accessible) included in ECC#1 are:

1. Main Control Panel (Relays, Resistors

etc.)

2.  Locomotive Control Computer MLC 691
3.  ADB 1, 2, 3, 4 and FDB
4.  Four Braking contactors (B1, B2, B3, B4)
5.  Silicon Control Rectifier (SCR) Assembly

High voltage and current are present within this cabinet. Do
NOT open a cabinet door except to access the Circuit Breaker
panels.
