AS PER CLW SPECIFICATION NO. CLW/ES/3/0057

FIRE DETECTION EQUIPMENTS FOR ELECTRIC LOCOMOTIVES

The Optical Sensor System in FDU is based on the principle where smoke scatters light. An infrared LED transmits intensive light pulses into the scattering chambers. The receiving element is screened off from direct IR light so that some of it reaches the receiver whose signal is evaluated by the electronics after three positively evaluated pulses, an alarm should be transmitted to the control Unit. If the detector is contaminated and the air is clean no signal is available at the receiver. If the air contains smoke, the receiver identifies signal that is transmitted to electronics.

RADAR ASSEMBLY/LOCOMOTIVE SPEED SENSOR

EQUIVALENT TO EMD PART NO. 40081692

RADAR ASSEMBLY/LOCOMOTIVE SPEED SENSOR

This Doppler K-band Radar measures the absolute ground speed that can be reliably used as the reference vehicle speed. By comparing the Doppler speed with each rotating axle speed, the slip/slide can be found out for each axle, this method is used on the GT46MAC or GT46PAC (WDG4/WDP4 locomotives). Radar Unit includes a signal-processing algorithm (Discrete Fourier Transforms) that determines the strength of return signal from a target. If the signal is strong enough, the output is turned on and the sensor is said to be “locked” (Good data) because different targets reflect different amounts of the radar energy back to the sensor (Like tracks, stones, wood, sand, etc), the sensor will lock at different distances from the target depending on such factors as target size, material and orientation. In general, large targets reflect more energy and the sensor will be able to distinguish them at a greater distance.

CONTACTOR STARTING (ST)

ELIXIR PART NO. EE/STC/2018/237

CONTACTOR STARTING (ST)

The engine starting contactor is a 2000A model. It is located in Electrical Control Cabinet (ECC2) cabinet. The movable main contacts and auxiliary interlocks are connected to a metallic plunger that moves in a vertical path through the center of the operating coil. When the coil is energized, this plunger is attracted upward; the main contacts close, and the auxiliary interlocks change position according to the design of the different model contactors. When the operating coil is de-energized, the return spring forces the plunger downward opening the main contacts and returning the auxiliary interlocks to their normal positions.
