xtrap Flashcards
how do you conserve battery?
neutral/key off- headlights off
saloon lights emergency
close cab doors to turn step light off
cab light off if daylight
what does major fault light and 2nd major fault light indicate
MCB tripped on the train
what does a minor fault light indicate
circuit breaker tripped in the electrical box
how long will the battery last
60 minutes
what kpa does the low pressure in MR light illuminate
650
safety loops opens at 580
low pressure on BP
light illuminates 430
safety loops opens 300
traction fault light?
this car light
speed input fault light
tacho cable, you only need 1 to work,
can check it by
Door button
Uncouple
Speedo won’t work
Trip reset
(vicers, safety loop)
parking brake applied
you can’t operate the spring park brake on the xtrap, this means main res is low or there are sticking spring park brakes
24v converter fault
1 or more 110 to 24vdc have failed
1 per car /3 per unit, need 1 for 24vdc to work
circuit breakers left hand side of door 2
BCU
panto 1
panto 2
aux 1
aux 2
tachy
safety loop circuit breakers
23Q2
23Q1
(also of note panto command)
when would you use the air conditioner control switch in the a side CB cabinet
incase of fire in the saloon
safety loop supply switch
in the a side CB cabinet, use for being rescued
if the panto won’t go up and above 90 volts
check buttons are not latched
try panto command in the A side then check the saloon circuit breakers.
try from another cab if still won’t go inspect saloon circuits breakers and the three way switch is in the automatic position
what fault can’t you fix with a train stable?
DTRS
how long do you wait after a stable?
5 seconds
how long will emergency saloon lights stay after a stable?
15 minutes
if there’s no voltage on the meter after you can visual and key in and on
the batteries are flat, isolates or a fuse gs blown, go for a walk and check the switch- look but no touch
if there are volts but and the panto won’t go up?
isloated or fuse blow.
can you can you manually raise/lower the panto
lower but not raise
make sure the train is stables before you open the panel
the three positions of the three way switch are:
auto
manual raising
lower and isolating
where is the manual raise and three way switch
right had side of door 4 trailer car under the panto
isolating a pantograph
stable the train
observe it us lowered
go to trailer and put three way switch or manual lower and isolate (manually lower with crank if necessary)
activate lead cab to raise other pantograph
report
when coasting under an overhead obstruction
always do a panto test first
use mode 1 on the EMS holding brake inhibit until clear of the section
if you have another can active light
the safety loop cannot close
make a cab to cab call
inspect each can for a cleaners key and activate the cab and see if the light extinguishes
once you find the defective can deactivate it it, this should help if not perform a train stable
if this doesn’t work the train can only be driven from the active cab you will need a competent employee
things to check if you can’t close the safety loop
110vdc check can fluro
trip lowered and set
master controller not in emergency
hand or foot is set
VICERS has not been activated
EMS position 2 (BP pressure in rescue)
main res above 580
another can active no illuminated( lamps test)
circuit breakers 23Q1 23Q2
——other cabs: check emergency stop button and all other trips are raised
if you can’t reset the safety loop after coupling it may be a fault with the coupler
you can use the bypass for any reason except not having 110- won’t work and no main res
when travelling on the safety loop bypass
you must hold the switch against the spring
there are no emergency brakes only letting go of the switch
you do not have to press the auto vigilance bypass
things that don’t work when you isolate the safety loop bypass
emergency position of the master controller
emergency stop button
hand foot pilot bypass
trip
BP and MR pressure switch
Auto Vigilance Bypass Switch
does not need to be held
is protected by a copper seal
auto vigilance bypass button will flash every 30 seconds for 10 seconds
(hand foot trip)
to isolate VICERS
use the key switch when:
fault light remains illuminated
safety loop is bypassed
auto vigilance is bypassed
abnormal operation of VICERS
i will VICERS operate on battery power if loss of overhead
yes
battery charger fault
is seen by fault light, perform train stable and book if rectified
train out of service if not rectified
if the battery charger fails
only emergency light available
if you lose one SIV
lose 1 HVAC per car
lose 1 air compressor
check circuit breakers left hand side of door 2 in trailer car
perform a train stable
if you lose 2 SIVS
BATH
battery charger ( emergency lights)
air compressors both
traction cooling fans both- (and traction)
HVACs all
position of the door isolation motor switches
1 motor release
2 motor isolate
3 normal
4 motor lock and close
to isolate a door with the mechanical switch
from position 3 normal to position 1 motor release, manually close doors then position 4 motor lock close
FWN both ends
1 door per car per side
where is the door loop bypass switch
A side cabinet
how do you know if you got a DER
flashing blue close light
door emergency handle activated fault light
flashing red ANSW button
DDU beeps
how do you reset a DER
tri key
where is the door motor isolation switch
left hand side above each door
traction faults
TCU will try to fix you will get 1 or more traction equip fault light (train lined)
traction fault light (this car light)
if time permits perform train stable
if this fails use the traction isolate switch in the affected car (may have to go for a walk to find the traction failt light)
if you have isolated the traction switch what lights will you see
the traction fault light will remain illuminated in the affected car
1 or more traction equipment should extinguish
Tacho speed input fault
DUSTvs
door button won’t work saloon doors can’t release
uncouple button won’t work
trip can’t reset
speedo won’t work
VICERS won’t reset
safety loop won’t close if BP can’t charge in train rescue
if time permits perform train stable
24v convert fault light
you only need one set for the train to run
check your seat to check you have at least one set
headlights and marker lights are also on this system
DTRS faults
press x button if that won’t work
stable and trip and reset the circuit breaker
activate cab
check TDN enters do radio test
if it doesn’t work deactivate the cab trip the CB and and reactivate, use the hand held in the cradle
PA faults
when you stable to recite you need to wait an extra 4 minutes, so 6 minutes stable
can you use the safety loop bypass if safety loop won’t close because of low main res?
no
can you isolate the safety loop if the it won’t close because of low BP
yes
if you have a bunch of fault lights check your one or more panto lowered fault light
it’s below your high voltage presence light
if someone tries to activate another can while your is activated what lights will you see?
circuit breaker lights major major 2nd and minor
VIGILANCE fault light
speed 0kmh
master controller coast
press button
if won’t reset then bypass key switch
if 2 HAVCs fault lights illuminate
2 SIVs out
battery charger fault light
other indications may be voltmeter not showing charge
emergency lights only
service brake fault light (during prep)
place master controller into full service
EMS switch to 1
release brake then immediately reapply
if service brake fault light and 1 or more brake equipment failt light don’t extinguish after full service application and release in EMS1
(during a prep)
turn safety loop bypass to test for 10 seconds
perform a stable
book
one or more brake applied/ wheel slide
sticking brakes
can only be fixed by isolating the bogie
drain the valve first
service brake fault light plus wheels slide light means it’s in
a trailing car 2/5
park brake applied light
never wanna see this we can’t switch them on or off
check isloating cocks and air leaks
if in service and train moves normally just book
if it’s sticking park brakes, manually release (aux res must be drained)
FWN
what happens if the compressor governor isolating cock is turned to isolate
it will leave the compressors in the state they were in
compressors not running?
stable
if MR between 580 and 750 drive normally and monitor
trip fails to lower
TEC RTA
check trip cock active
open if closed
if still won’t lower keep it raiser and drive on the secondary
trip fails to raise (trailing)
RTA
isolate trip cock active in aux panel
keep it raised by any means necessary
trip fails to reset
check other fault lights
manually reset the trip with the spring button
check the cock on the panel if it won’t lower and set drive on the secondary
whistle not sounding
hit the lever
check the cocks in a side equipment cabinet and aux panel
if whistle sounds continuously
depending on high/low tone isolate the high/low VICERS isolating cocks
if this doesn’t work use the cock in the six panel
