25
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
26
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
27
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
28
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
29
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
30
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)
31
to isolate VICERS
use the key switch when: fault light remains illuminated safety loop is bypassed auto vigilance is bypassed abnormal operation of VICERS
32
i will VICERS operate on battery power if loss of overhead
yes
33
battery charger fault
is seen by fault light, perform train stable and book if rectified train out of service if not rectified
34
if the battery charger fails
only emergency light available
35
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
36
if you lose 2 SIVS
BATH battery charger ( emergency lights) air compressors both traction cooling fans both- (and traction) HVACs all
37
position of the door isolation motor switches
1 motor release 2 motor isolate 3 normal 4 motor lock and close
38
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
39
where is the door loop bypass switch
A side cabinet
40
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
41
how do you reset a DER
tri key
42
where is the door motor isolation switch
left hand side above each door
43
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)
44
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
45
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
46
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
47
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
48
PA faults
when you stable to recite you need to wait an extra 4 minutes, so 6 minutes stable
49
can you use the safety loop bypass if safety loop won’t close because of low main res?
no
50
can you isolate the safety loop if the it won’t close because of low BP
yes
51
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
52
if someone tries to activate another can while your is activated what lights will you see?
circuit breaker lights major major 2nd and minor
53
VIGILANCE fault light
speed 0kmh master controller coast press button if won’t reset then bypass key switch
54
if 2 HAVCs fault lights illuminate
2 SIVs out
55
battery charger fault light
other indications may be voltmeter not showing charge emergency lights only
56
service brake fault light (during prep)
place master controller into full service EMS switch to 1 release brake then immediately reapply
57
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
58
one or more brake applied/ wheel slide
sticking brakes can only be fixed by isolating the bogie drain the valve first
59
service brake fault light plus wheels slide light means it’s in
a trailing car 2/5
60
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
61
what happens if the compressor governor isolating cock is turned to isolate
it will leave the compressors in the state they were in
62
compressors not running?
stable if MR between 580 and 750 drive normally and monitor
63
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
64
trip fails to raise (trailing)
RTA isolate trip cock active in aux panel keep it raised by any means necessary
65
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
66
whistle not sounding
hit the lever check the cocks in a side equipment cabinet and aux panel
67
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
68
electrical rescue max combined units is 3- cars 9
normal speed position 2 both trains safety loop supply switch in all motor cabs of the disabled if flat batteries or no charge
69
xtra pushing xtra non electrical
40km assisting 4, disabled 1 observe low BP pressure fault light then charge the brake pipe in full service with pilot set, coast continuity full emergency on whole unit service on disabled/lead unit only disabled/lead has no holding brake beware of rolling assisting has reverser in forward pilot set provide power as required and vigilance
70
xtrap pulling xtrap non electrical
reduced speed ems 3 disabled ems 4 assisting observe low BP pressure fault light charge brake pipe continuity emergency on full unit, service assisting/lead only disabled is in forward hand set and vigilance
71
xtrap pulling xtrap LOW BATTERY coupled electrically
low key like if one unit had lost 2 sivs on a 6 car speed 15 ems 2 both units continuity- assisting should trip 23q1 23q2 and reset when other consist hits ESB both drivers have emergency, assisting has service brake only one key/cab active
