727 – AL L1 Delta T-NT Intercooler
Cause
Corrective action
The differential temperature at
sensors B26 and B90 has violated
limit value 1. The LT coolant inlet
temperature is too high in relation
to the ambient air temperature.
1. Check cooler (plant side) for contamination.
2. Check operation of fan (plant side).
3. Contact Service.
