WDG4/WDP4 Locos MR2 Pressure is low with PCS open indication

WDG4/WDP4 Locos

MR2 Pressure is low with PCS open indication

Probable Reasons:

  1. Ensure M R1 pressure.
  2. MR2 – Auto blow down valve blowing continuously.
  3. Leakage in BP Pipe.
  4. Leakage in BC Pipe.
  5. Leakage in BC Eq. Pipe.
  6. Compressor Defect.

Action to be taken by LP:

  1. Trouble shoot and create.
  2. Close to shut off position (manual position – spindle inside).
  3. Check and arrest the leakage.
  4. Check and arrest the leakage, if unsuccessful isolate the truck by closing Brake Cylinder COC.
  5. Ensure BC Eq. Cocks are closed.
  6. Check oil level or unusual sound.

WDG4/WDP4 Locos Dead Loco Movement

WDG4/WDP4 Locos Dead Loco Movement Shut down the Engine as per procedure and attach with the working loco. If equalizer pipes are connected work the loco without any change. If BP pipe only connected the following procedure to be carried out. Drain MR1 and MR2 completely, then close the drain cocks. At any one end open BC Equaliser and M R Equaliser COC. Connect BP Pipe and open BP Angle cocks. Open Dead Engine cock (in CCB 1.5) or Turn Dead Engine knob in 'Dead In' position (in CCB 2.0) located in the nose compartment. Ensure M R pressure is builds to 1.8 kg/cm2 in the dead loco. Destruct the BP and ascertained loco brake is getting applied in the dead loco and BC Pressure is building up to 1.8 kg/cm2.. Create BP Pressure to 5.2 kg/ cm2. and ascertained loco brake is getting released. Ensure air is leaking through the dead loco BC Equaliser pipe during application and releasing of brakes. If not the BC Equaliser COC Position is to be ascertained for proper pos
