10.14 Stopping Engines
There are six ways to Stop the Engine:
1. On the Engine Control Panel, set the Isolation switch in
START/STOP/ISOLATE, then press the EMERGENCY FUEL CUT
OFF & ENGINE STOP push button switch (this switch is also known
by its electrical reference designator, EFCO/STOP). Since Control
system reaction time after pressing the EFCO/STOP push button is
very quick, the push button need not be held in until the Engine stops.
2. Press one of the Emergency Fuel Cut Off (EFCO) push buttons. One
is located near each Fuel filler, on the side of the Locomotive Under
frame. These push buttons operate in the same manner as the
Engine Control panel EFCO/STOP push button and need not be held
in nor reset.
3. Pull the Lay shaft (injector rack manual control lever) outward,
towards the right side of the Locomotive and hold it there until the
Engine stops completely. The lay shaft overrides the engine
governor, forcing the fuel injector racks into the "No Fuel" setting.
4. Close the Low water detector test cock (lever horizontal). After some
Engine coolant leaks down, the low water detector trips, oil dumps
from the Governor low oil shutdown device and the Governor stops
the Engine.
5. To simultaneously stop all On-line Engines in a multiple-unit tandem
from the cab of the lead unit, press the Red STOP section of the MU
STOP switch on the right side of the No.2 Control Console. (The
switch remains in stop until the green RUN switch section is pressed).
6. Pull out Low Oil shutdown plunger on the side of the Engine
Governor.
