17
Q

Left hand console panel

What is the compressor contactor switch?

A

Turns on and off the operation of the Air compressor on the motor car (local)

18
Q

Left hand console panel

What is the Brake pipe test switch and bell button?

A

Activates a brake pipe reduction to test the operation of the brake. (Used in conjunction with the bell button when switch is On

19
Q

Left hand console panel

What is the traction equipment reset button?

A

This button is used to reset the traction system when traction motors fail to power or the Rheo brake fails to operate. If this doesn’t reset the defect, you will need to isolate the fault.

20
Q

What is apart of the primary safety apparatus?

A

T - Trip
E - Emergency application valve
C - Control governor
H - Hand and foot pilot valve
A - Anti neutralisation device
V - VICERS activation valve

21
Q

When running on the secondary circuit, how often will the control governed bypass button flash and how long do you have to push it?

A

The bypass button will flash every 30secs, if it is not pressed, an emergency application of the brakes will occur after 10 secs

22
Q

What does the local fault light indicate on the Comeng?

What does the line switch fault light indicate on the Comeng?

A

There is a fault within the power supply to the traction motors or line breaker case

24
Q

What does the Rheo brake fault light indicate on the Comeng?

A

A fault with the Rheo brake system

25
Q

What does the MA fault light indicate on the Comeng?

A
