10 – SS T-Coolant Charge-Air Cooler
Cause
Corrective action
The coolant temperature in the
charge-air cooler at sensor B26
has exceeded limit value 2.
Coolant temperature in charge-
air cooler too high.
1. Reduce power.
2. Check whether alarm 23 is pending.
3. Check cooler (plant side) for contamination.
4. Check operation of fan (plant side).
5. Contact Service.
15 – LO P-Lube Oil
Cause
Corrective action
The lube oil pressure at sensor
B5.1 has undershot limit value
1. The lube oil pressure is too
low.
1. Check engine oil level (→ Page 129).
2. Contact Service.
16 – SS P-Lube Oil
Cause
Corrective action
The lube oil pressure at sensor
B5.1 has undershot limit value
2. The lube oil pressure is too
low.
1. Check engine oil level (→ Page 129).
2. Contact Service.
23 – LO Coolant Level
Cause
Corrective action
Coolant level at switch F33 is
too low.
1. Check engine coolant level (→ Page 138).
2. Check relief bore of charge-air coolant pump (→ Page 154).
3. Visually check coolant circuit for leaks.
4. Contact Service.
25 – HI P-Diff. Lube Oil
Cause
Corrective action
The differential oil pressure at
sensors B5.1 and B5.3 has
exceeded limit value 1. The
differential oil pressure is too
high.
1. Replace engine oil filter (→ Page 134).
2. Contact Service.
26 – SS P-Diff. Lube Oil
Cause
Corrective action
The differential oil pressure at
sensors B5.1 and B5.3 has
exceeded limit value 2. The
differential oil pressure is too
high.
1. Replace engine oil filter (→ Page 134).
2. Contact Service.
