5 – HI T-Charge Air
Cause
Corrective action
The charge-air temperature
measured at sensor B9.2 has
violated limit value 1. The charge-
air temperature is too high.
1. Reduce power.
2. Check whether alarms 9 and 10 are signaled.
3. Contact Service.
6 – SS T-Charge Air
Cause
Corrective action
The charge-air temperature
measured at sensor B9.2 has
violated limit value 2. The charge-
air temperature is too high.
1. Reduce power.
2. Check whether alarms 9 and 10 are signaled.
3. Contact Service.
9 – HI T-Coolant Intercooler
Cause
Corrective action
The charge-air cooler coolant
temperature measured at sensor
B26.has violated limit value 1. The
charge-air cooler coolant
temperature is too high.
1. Reduce power.
2. Check whether alarm 23 is signaled.
3. Check cooler for dirt (plant).
4. Check fan operation (plant).
5. Contact Service.
10 – SS T-Coolant Intercooler
Cause
Corrective action
The charge-air cooler coolant
temperature measured at sensor
B26.has violated limit value 2. The
charge-air cooler coolant
temperature is too high.
1. Reduce power.
2. Check whether alarm 23 is signaled.
3. Check cooler for dirt (plant).
4. Check fan operation (plant).
5. Contact Service.
15 – LO P-Lube Oil
Cause
Corrective action
The lube oil pressure measured at
sensor B5.1 has violated limit
value 1. The lube oil pressure is
too low.
1. Check engine oil level (→ Page 132).
2. Contact Service.
