Explain the electricity supply…..
25,000 volts - Collected by the PANTOGRAPH located in the PMLW vehicle - Current travels via the LINE CIRCUIT BREAKER located in the HIGH VOLTAGE BOX - Current goes into the MAIN TRANSFORMER where the AC is converted into DC - This output from the Transformer is then sent to the 2 LMA Propulsion Modules - The power is then distributed to the TRACTION MOTORS via the Motor Converter Modules and to the AUXILIARY SYSTEMS via the Auxiliary Converter Modules
The Line Circuit Breaker is located in the High Voltage Box on the roof next to the Pantograph. Its purpose is to connect or disconnect the High Voltage system to/from the electricity supply. When would the LCB open? (7)
ADD operated
Pantograph has gone overheight
Neutral Section
Fault on traction equipment requires disconnection from OLE
Pan Down command has been given by the driver in an active cab
Stabled mode is selected by the driver
Line voltage is either too high (27,500 V) or too low (17,500 V)
At what high and low OLE voltages would the LCB (Line Circuit Breaker) open at?
High = 27,500 volts
Low = 17,500 volts
What does TCMS stand for?
Train Control and Monitoring System
On the TCMS screen you will get a picture of the Pantograph, it will either be in a raised position or a lowered position. If it’s raised and everything is ok the picture is blue and through a Neutral Section the picture is yellow. If the Pantograph is in a lowered position and you are on the move, what should your actions be?
Press Pan Down and stop immediately
(Yellow picture = Overheight operated……. Orange picture = ADD operated)
Compressed air raises the Pantograph. However, at start up, if the air pressure is below 5.8 bar, what is used to raise the Pantograph?

How do you raise the Pantograph?
Press “Auxiliaries On” to energise the cab
Wait for the Pan button to flash
Press and release the Pan button
Confirm Pantograph is raised by looking at the TCMS symbols (blue symbol in the raised position)
If you press Pan Down from an active cab, what will this do?
First it trips the LCB (Line Circuit Breaker) and then lowers the pantograph
What are your actions if the ADD is operated…. how will you know about it?
Pan down - stop immediately - contact the signaller - acknowledge the TCMS alert
(you will know because the orange lowered pantograph symbol will appear on the TCMS)
How do you isolate the ADD?
Via the TCMS (under Power and Brake)
What are your actions if the overheight control has operated…. how will you know about it?

How is Sensitive Door Edge (SDE) Anti-Drag Function different to Door Obstacle Detection?
It can recognise smaller, trapped items that still allow doors to close
(STATIC detection and DYNAMIC detection (EBA within 300 metres of doors closing at a station))
What are the two types of anti-drag detection?
Static detection - Unable to get interlock and you receive TCMS message
Dynamic detection - Detected whilst the train is in motion LESS THAN 300 METRES FROM THE PLATFORM, you will get….. EBA, door interlock goes out, BIL lights on affected vehicle, TCMS error message, CCTV images of the problem
How do you reset an EBA caused by the dynamic detection of the Sensitive Door Edge (SDE) Anti-Drag Function?
Either by:
Mechanically locking/unlocking the affected door using the out of service lock
Or by
Opening and closing cycle of the doors (only possible if the train is still fully accommodated at the platform)
If you have received an EBA caused by the dynamic detection of the Sensitive Door Edge (SDE) Anti-Drag Function, what MUST you do before moving the train?
(EBA if detected within 300 metres of leaving a station)
