CONTROL GOVERNOR BYPASS BUTTON
What pressure does the Control Governor open and release BP pressure - removing power from Master Controller?
310-340 kPa
What pressure does the Control Governor close and restore pressure to the BP - restoring power to the Master Controller?
400-430 kPa
What is BP pressure when BCH is in FULL SERVICE Reduction?
380-410 kPa
What pressure does BP need to be at to set TRIP?
0 kPa
When BP is fully charged (550 kPa) what pressure is Main Res. at?
585 - 725 kPa
When you do TRIP functionality test and you strike the TRIP, what pressure do you want to observe the BP pressure gauges reduce to?
150 kPa
What is BP pressure when BCH is at MINIMUM REDUCTION?
500 kPa
What is BC pressure when BCH is in EMERGENCY?
275 kPa
Once coupled what has to be observed at start of Continuity test (with 2 drivers)
Attaching driver:
Confirm Park Brakes applied
Place BCH to Step 7
Observe BC pressure at approx 250 kPa
Assisting driver:
Observe BC pressure at approx 250 kPa
How long does assisting driver open Van Area EC for to test continuity?
15 seconds
What does assisting driver want to see BP pressure drop to when they open Van Area EC?
Below 300 kPa
After 15 seconds, the assisting driver closes the Van Area EC … what do they want to see BP pressure increase to?
minimum of 425 kPa
How long does the assisting driver give the BP pressure to increase?
40 seconds
What does BP pressure need to be to divide?
Less than 250
What position does reverser have to be in to divide?
Neutral
What does anti-neutralisation device do?
Stops us running in neutral over 8kmh
How long will door chimes for if obstructed?
60 seconds
What positions of reverser do you not have to hold the hand pilot valve down
Off and neutral
Why will the Door Close Button Flash (FDCL)?
Door System Faults
Control CB tripped in rear cab
Auxiliary CB tripped in any cab
PLC CB tripped in any trailing car
Rear Motor tail lights turned off
Coupler senses it is still coupled
Second BVICS opened
Open circuit in Train Cable
Why does the Low Pressure flag pop up?
If Main Res. air falls below 500kPa
BVICS closed
EP Brake CB (top left) tripped
- this isolates EP and Rheo brake
EP MR Isolate Cock turned vertical (closed)
- Isolates flow of MR air to flag and it rises
Attaching - What does assisting driver check from the platform - without entering the pit?
Coupling mouthpieces in place and good condition
MR and BP cocks are open
Couplers are aligned
If viewable … electrical coupling cocks are in coupling position
Why does the Motor Alternator overspeed?
Control CB trips???
