Q

if you have another can active light

A

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

tri key

42
Q

where is the door motor isolation switch

A

left hand side above each door

43
Q

traction faults

A

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
Q

if you have isolated the traction switch what lights will you see

A

the traction fault light will remain illuminated in the affected car
1 or more traction equipment should extinguish

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
