WHEEL SLIP CONDITION:
While starting train, when rail conditions are
exceptionally poor, any occasional flash of the light indicates normal wheel
slip control. Automatic sanding may also occur. Do not reduce throttle setting
unless severe lurching threatens to break train.
WHEEL SLIP CONDITION ON OTHER LOCOMOTIVE:
If another
Locomotive is in tandem, connected by MU jumper to this Locomotive,
detects any condition that causes it to light its WHEEL SLIP indicator, it
energizes the train line that lights the WHEEL SLIP indicator on this
Locomotive.
WHEEL OVER SPEED CONDITION:
The indicator light flashes ON and
OFF to indicate wheel (Traction Motor) over speed, which can be caused by
excessive track speed or by simultaneous slipping of all Locomotive wheels.
4.
FLASHER LAMP LIGHT:
This indicator flashes ON/OFF when either
outside Flasher light (at cab end or long hood end) is flashing or the
outside Flasher lamps are connected through Lights Circuit Breaker.
So the Lights CB is necessary to switch ON for Flasher Lights
operation.
5.
PCS OPEN LIGHT:
The Air Brake system trips Locomotive control
system Pneumatic Control Relay (PCR), whenever it initiates a safety
control or Emergency Air Brake application. When PCR trips, it
switches ON the PCS OPEN light and Locomotive control system
Do not, under any circumstances, tow a Locomotive having
sliding/Locked Wheels or move such a Locomotive in tandem.
