051 – HI T-Lube Oil
Yellow alarm.
Associated parameter 2.0125.931
Cause
Engine oil temperature after oil
heat exchanger too high (limit
value 1). Oil heat exchanger
contaminated, coolant
temperature is too high.
Insufficient oil volume flow rate.
052 – SS T-Lube Oil
Red alarm. Engine stop.
Associated parameter 2.0125.932
Cause
Engine oil temperature after oil
heat exchanger too high (limit
value 2). Oil heat exchanger
contaminated, coolant
temperature is too high.
Insufficient oil volume flow rate.
053 – HI T-Intake Air
Yellow alarm.
Associated parameter 2.0123.931
Cause
Intake air temperature too high
(limit value 1).
054 – HIHI T-Intake Air
Yellow alarm.
Associated parameter 2.0123.932
Cause
Intake air temperature too high
(limit value 2).
057 – LO P-Coolant
Yellow alarm.
Associated parameter 2.0101.921
Cause
Coolant pressure after engine
too low (limit value 1). Flow too
low, static pressure too low.
