Electrical
or Mechanical problems – identify & rectify.
Mechanical Defects
Check LR%
value in Power Data or Excitation / HP screen, if it is less than 100 %, it is
Mechanical Problem (Engine).
Check Fuel
Return Sight glass for any Air bubbles / water
Check Fuel
Filter condition gauge / bypass sight glass
Ensure Fuel
level in tank
Check Air
box inspection cover, De-compression plugs and BAP Pipeline for any leakages
Water
temperature is high – Trouble shoot
Electrical Defects
If LR % is
100, but HP is less, it is Electrical Problem
Check both
Truck - Tor. Ref. & Feedback values
Only
single truck output - Recycle TCCs & try
If still
not rectified, disable Truck & enable after working some time
Truck / TM
is Disabled – check the remark & enable it if no remark.
Radar
defects – Ensure Radar face is clear without any obstruction
Check for
any Radar failure messages – If so, remove Radar Coupler & try
TCC
temperature is high – check TCC blower breaker, reset if tripped, disable TCC
for some time & enable later.
TM
temperature is high – ensure both trucks giving power, if not, recycle TCCs /
enable truck
C/stand
problems / Governor problems – change the control stand & try / contact
shed.
TM Speed
sensor defects – Isolate / Remove sensor & try
LCC
problems - recycle computer control breaker, GFB.
Note:
·
In lower loco speeds, i.e. Less than 25 KMPH, engine
HP will be less even though TH is in 8th notch
·
In converted P4 locos with 6 TMs, 8th
notch HP is set at lesser value
·
If trailing loco shutdown on run while working MU,
leading loco’s TCC/TM temperature may increase & HP will reduce - Ensure
rear loco is working
