The NWGC130 package is designed to control an on-car generator that also has the capacity to feed power to the HEP trainline system. It is designed for generator car use only. It can only power the trainline for the HEP system, and is not designed to also directly feed the circuit breaker panel inside the car.
An Adobe Acrobat version of the brochure for this product is also available in our PDF Files area.
Note: The system shown here is only one example. Several variations have been developed for different generator sizes, voltages, and manufacturers.
Features of the NWGC130:
- Components labeled to permit easy maintenance
- Generator Engine Controls:
- Generator Breaker for turning on and off general engine electrical system. May be used as emergency shut-down of engine
- Engine Control switch for selecting "Start / Run" or "Delay Off / Cool Down". When set to the "Start / Run" position, the engine preheat system will automatically start and run for a brief period of time. After the engine preheat stage is completed, the engine will automatically start up and run. In the "Delay Off / Cool Down" position, the engine will automatically run at idle speed for a period of time before automatically shutting down.
- Generator Engine Indicators:
- Hour Meter
- 12 Volt Engine Alternator Meter
- Coolant Water Temperature
- Oil Pressure
- Engine Preheat Indicator
- Engine Started Indicator
- Engine Alternator Indicator
- Engine Overcrank Indicator - Indicates that an attempt to start the engine was made, but due to an engine or fuel related problem it would not start
- Generator will automatically shut down when any of the following fault indicators are lit:
- Low Oil Level - Time Delay Controlled to Prevent Engine from shutting down due to sloshing caused by train motion
- Low Coolant Level - Time Delay Controlled to Prevent Engine from shutting down due to sloshing caused by train motion
- Low Oil Pressure - Time Delay Controlled to Prevent Engine from shutting down due to sloshing caused by train motion
- High Water Temperature
- Engine Overspeed
- Generator Output:
- 0-600 volt AC Voltmeter
- 0-200 ampere AC Ampmeter
- Optional Frequency Meter
- These meters are connected to a meter switch that allows for individual measurement of the voltage and current that the generator is feeding to each of the three phases. Meter switch may also be set to "off" to indicate any induction-caused problems with the meter reading.
- HEP and HEP Feed:
- HEP "Feed Off", "Loop Test", and "Feed On" switch
- "Trainline Loop Complete" Indicator light
- The HEP Feed switch is normally left in the "Feed Off" position. If it is desired to feed the HEP trainline with the on-car generator, the switch is turned to the "Loop Test" position. If the control loop is complete between all the cars (that is, all of the car to car power cables are connected properly), the "Trainline Loop Complete" indicator will light. The switch may then be turned to "Feed On", which will feed power from the generator to the other cars on the train.
The generator control package shown here does not have automatic start and switching of the generator power. An alternative Northwest Rail Electric Generator Control, the NWGC-500 package, is designed for situations where the generator is used as a back-up power source, and selection between multiple sources of power is needed.
