Control Air Supply
1. General
The compressed air necessary for the air spring air (exhaust valves) and the turning
gear interlock comes from the control air board supply. The air must be clean and dry
to prevent blockages in the control units.
If the control air board supply system becomes defective, a decreased quantity of
compressed air will come from the starting air system.
The shut-off valves, pressure reducing valve, filters etc. that are necessary to supply
air to the different units are shown in the control air supply unit A (see Fig. 2 and
Fig. 3).
The numeric titles used to identify the parts of the equipment in the illustrations are
the same as those in the Control Diagram 4003−2.
