Personal brake test
(Emergency, Step 3, 2, 1, hill start, emergency plungers)
253
Before you couple up, why do you have to make sure that the batteries are switched on on the dead unit?
Because if they are not then the electrical connection box would not come forward and you would not be able to couple up with the unit
254
If you are trying to uncouple and the electrical connection box doesn't retract, why do you need a second person?
One person presses the uncouple button..... whilst at the same time.....
The other person touches the coupling sensor with something metallic (I.e. T Key)

By operating the FDS Isolation Switch in the 350/3 Unit
256
If you press IC on the PIS, how do you know when the Guard has picked up the phone?

Which vehicle houses the batteries?
PTS
(The batteries power up the TMS, Auxiliary Compressor to allow you to raise the pantograph after 10 minutes, driving cab controls)
264
Why do you have 2 Auxiliary Convertor Units? What happens if one of the ACUs fail?
ACU 1 provides electrical power to things like: Main Compressor, TCU fans, ACU fans, Main Transformer fans, Brake Resistor fans, Air conditioning
ACU 2 provides electrical power to things like: (Sean Penn was LaTe going to BeD.......) Safety Systems, PIS, Lighting circuits, TMS, BCU, Door circuits
In the event of one ACU failing, all of the above will receive power from the working ACU but some systems will shut down automatically to avoid overload I.e. air con and lighting
265
How many TCUs are there on a single Unit?
2 (1 on both DMS)
266
What is the main function of the Traction Convertor Unit?
To supply power to the traction motors as demanded by the PBC
267
What are the 2 main safety circuits?
Emergency Brake Loop
Door Loop
268
Who is the only person that can operate the Parking Brake Isolating Cock?
Rolling Stock Technician
269
If you operated the Compressor Governor Isolation Cock on the DMS (compressor governor failure), the compressor will run continuously..... what do you have to check?
Safety valve is still venting the air (@ 11.3 bar)
270
What are the three isolation cocks on the BCU?
BIC
Parking Brake (can only be applied by a Rolling Stock Technician)
BUIC
271
What vehicles are ASIC on (if there is a leak of the air suspension), and what do you have to do if operated?
DMS 1 and DMS 2
Also operate the Air Suspension Vent Cock because the system does not self-vent itself
272
If you have to BUIC, when would you access it internally instead of externally?
If you're in a tunnel, or anywhere where access to the external BUIC is difficult (I.e. station platform)
273
What is the main function of the Auxiliary Compressor? (Starts automatically when you put the batteries on, key in and Neutral) How long does it take to charge before you can raise the Pantograph?
To charge the pantograph air system to enable you to raise the pantograph if the Unit has been shut down
......
Takes 10 minutes to charge (look for the FIP "Aux Low Pressure" light to go out) and only then can you raise the pantograph
274
Why do you need to make sure the Acknowledge Configuration box is ticked on the TMS?
Because if it isn't then:
UDS will not work
PIS will not work in any Units running in multiple
Brake Test fails in prep
275
What are the 3 main components that feed information to the CCU?
Traction Convertor Unit
Auxiliary Convertor Unit
Brake Convertor Unit
276
How does information travel to the CCU from the TCU, ACU and BCU?
Via Multi Vehicle Bust jumper cables
277
How long can it take for power to return after a Neutral Section?
Up to 20 seconds
278
How would you visually be aware of the ADD activating?
VCB light comes on
Line Light goes out
(physically, you would also lose power)
279
Before you raise the Pantograph (batteries on and Auxiliaries Low Pressure light goes out....), what do you first have to select (immediately after batteries on)?
AC Power
280
When looking at the outside of the DMS, what is the thing that looks like a fan?
Brake Resistors and Cooling Fan
281
Each vehicle has HVAC.... where is it?
On the roof
282
Apart from the HVAC, what is the only external component you find on the TC vehicle?
BCU
283
What is the big red cable called next to the Main Transformer on the PTS?
High Tension Cable
