Screens Details
1. SCREENS
The Driver display has pre-defined dedicated screens in order to monitor real time process variables pertaining to a particular section or sub-system of the locomotive. However, such screens are meant for online monitoring by technical staff whenever required. The locomotive driver, however, needs to view the default screen only most of the times. The screens have been designed to take care of the specification requirement. The details of the screens are explained below.


2. SUB-SYSTEM STATUS
In the sub-system status menu, the names of the sub-systems are listed. To navigate to default screen, press "HOME". To navigate to list of screens, press . The isolated sub-system will be shown in red.


3. HIGH VOLTAGE CIRCUIT
In the high voltage circuit screen, Harmonic Filter status and Hotel Load status are additionally provided. Other variables are already available in the default screen. Hotel Load facility is available only in WAP7 & WAP5 class of locomotives.


4. I/O SIGNALS
The physical input/output signals, both analog and digital, can be viewed using this multi-level screen. In this screen, the description of the signal, name used in FUPLA and the location of the signals and the actual value can be viewed (channel+slot+connector+pin number eg: 12/EA05 : means channel-12, E slot, A connector, pin-5). These screens will be quite useful for troubleshooting.


5. TRACTION CONVERTER
In traction converter screen, converter related parameters are displayed. The screen is split into two columns, one for each traction converter. The process variables displayed include pre-charge & input contactor status, oil pressure & temperatures, input power & ventilation level. Other displayed parameters are already available on default screen.


6. AUXILIARY CONVERTER
The Auxiliary Converter screen provides very vital process variable display about the BUR, which will help in easy trouble shooting. The variables include Auxiliary winding voltage, Total current in the auxiliary winding, dc link voltage & dc link current of each BUR, output voltage and output frequency. Please note that there is no direct signal available for the output voltage whereas the displayed value is calculated from dc link voltage and output frequency considering constant v/f relation. The screen also provides the status of BUR grouping contactors.


7. TRACTION MOTOR
The traction motor screen is also vertically split into two columns, one for 3 motors belonging to one bogie. The relevant process variables like input contactor status, dc link voltage, ventilation level, converter input power, wheel slip status, speed of each traction motor reported from speed sensor and temperature of each traction motor reported by the temperature sensor are displayed.


8. AUXILIARY SYSTEM
The auxiliary system screen essentially displays the status of various auxiliary machines, as to whether these are OFF or ON. It also indicates the BUR status and BUR input volatge. The auxiliary machines considered are Compressors (1,2), Oil Cooling Blowers (1,2), Oil Pump Converter (1,2), Oil Pump Transformer (1,2), Traction Motor Blower (1,2) & Machine Room Blower (1,2).


9. BRAKING SYSTEM
The braking system screen displays the process variables related to braking, which include locomotive speed, master controller position (traction/braking region), BE demand and BE Actual, Pneumatic Brake Effort demand (when regeneration fails), regenerated power & energy as well as status of compressor.


10. ENERGY MONITORING
The screen for energy monitoring displays the energy consumed and regenerated. The cumulative value is the one taken from the NVRAM of DIA computer, which is available on MVB. The trip energy is calculated by the driver display itself from the time of switching ON. This value is not saved in any memory and will vanish once the locomotive is OFF. Trip energy can be used for comparison of driver performance under identical conditions of operation.
The regeneration ratio (energy regenerated/energy consumed) is calculated by the driver display and displayed. This factor also provides a measure of the efficiency of regeneration and is a good comparison tool.


11. TEMPERATURES
The temperature screen provides various temperatures recorded by sensors and the same can be compared with the converter input power. The temperatures of transformer oil, traction converter oil and traction motors are displayed alongwith converter input power for each bogie.


12. PRESSURES
This screen shows the pressure variables. It include Transformer oil pressure, converter oil pressure, MR pressure, BP pressure and status of BC1 & BC2.
