siemans Flashcards
what happens when you stable a siemans?
no saloon lights at all no marker lights, doors will lock. so when stabling on the mainline it is important to be i contact with TC and preferable under protection of home signals, at a platform and not activating a level crossing
what does the general fault light flashing indicate?
there is a fault in the sub-system on the train. it will also illuminate for maintenance requirements
if general fault light is flashing and you acknowledge can it flash again
yes if there’s another fault, keep pressing the button
what does the 1st unit or 2nd unit fault lights tell us
which unit the fault is on, you could have traction systems if it was on the motor you are in
what are the three possible causes for critical defect?
critical fail in the pneumatic friction brake system
complete loss of auxiliary power 2 sivs
defective wheel slip unit affecting the operation of the sanders
what can you inspect if you have a critical defect indicator?
friction brake and monitoring (all cars of affected unit)
static inverter monitoring (trailer)
what does a maintenance fault light tell you?
that unit is due for a service
safe operation of the train should not be affected
maintenance fault light examples
single siv out
isolated/defective door
brake is not released
one HVAC defective
PA system is defective
CCTV defective
a compressor fault
traction system is defective or requires maintenance
fault with sanders that’s not due to to wheel slip unit
what can you do to simulate a motors all out situation or dive the train while asking for less power
trip one of the TCU CBs
what does the reduced performance light indicate
one or more motor cars are failing to deliver traction power (a TCU is not functioning),
the TCU will automatically ok so late the traction motors, no action required by driver. traction system light will illuminate if it is you lead motor
what should you do to try and reset a reduced performance light in a slip/slide event
MC to 0 for 2 seconds, progressively resume powering (ask for less)
another cab active light
buzzer will sound if you are attempting to be a second active cab. If you can’t deactivate a cab trip cab train manned in that cab
CCTV screen failure
normal in centre motors
inspect CCTV central Control
DCDC inverter PA PI display
failure of PID
check DCDC inverter PA PI display
check Passenger Information Display
DRRS faults / reset
deactivate cab
trip and reset DTRS CB
activate cab
enter TDN/ radio test
TMM
DTRS isolate
deactivate the cab
trip the CB out
reactivate cab
place portable in cradle
PA failure during prep
check the PA system CB (dma)
check DCDC inverter PA PI display
stable, must be longer than 2 minutes
if during running use DTRS and book
one panto fails to raise
both high voltage and panto up will illuminate
inspect pantograph control in local driving cab
inspect panto motor in affected driving cab
try and raise from another cab
raise manually
all pantos fail to raise
it could be a problem with the circuit or lack of battery 82 volts check panto control CB
check if will raise from another motor
try a stable wait 1 minute trip panto motor
raise lead manually with crank handle clockwise until you feel pressure
observe it has raised
panto up button
reset the CB
TMM
panto fail to lower when train stabled
inspect Train Stable HSCB & Light Control CB in local cab
inspect Shutdown Delay in TRAILER car
trip TCU cb incase the train thinks it’s in motion
TMM
panto fail to lower when panto down button pressed
inspect panto motor
leave it in a siding as is- better for fitters
trip reset and panto down again
isolating a panto
key off
stable
trip panto motor
lower manually if required
key on
panto up
visually inspect it has remained lowered
TMM
lose both SIVS
no air con
emergency light only
battery charger stops charging
half drivers cab fluros
no air compressor
(BATHG -the T is TCU)
how can you manually start a SIV
stable
trip panto motor
raise local panto with crank handle
go to SIV A side underframe use tri-key to open small rectangle box and press self excite, hold until you hear a click
trip it back in
activate cab
push panto up
TMM
panto fails to lower when train stable is pressed
inspect Train Stable HSCB& light control- reset or trip and reset
inspect shutdown delay- same
TRIP the TCU it may not recognise the train has 0 speed which prevents a stable
to isolate a panto
stable
trip that panto motor
reactive and panto up while that remains a tripped out
when a panto is isolate which fault lights will you see
both line voltage and panto up
if panto up is illuminated- there is a panto down
door circuit breakers in a dm car
door control
closed and locked loop
1-4
door circuit breakers in a t car
door control t car
doors 1-4
respond to flashing door close light at a platform
normal procedure from cab
trip and reset door control train lines
try close
