058 – SS P-Coolant
Red alarm. Engine shutdown.
Associated parameter 2.0101.922
Cause
Coolant pressure after engine too
low (limit value 2). Insufficient
volume flow, static pressure too
low.
063 – HI P-Crankcase
Yellow alarm.
Associated parameter 2.0106.931
Cause
Crankcase pressure too high (limit
value 1). Restrictor valve in
crankcase breather is closed too
far, air filter is faulty, oil separator
is clogged, piston rings are seized,
other damage to crank drive.
064 – SS P-Crankcase
Red alarm. Engine shutdown.
Associated parameter 2.0106.932
Cause
Crankcase pressure too high (limit
value 2). Restrictor valve in
crankcase breather is closed too
far, air filter is faulty, oil separator
is clogged, piston rings are seized,
other damage to crank drive.
067 – HI T-Coolant
Yellow alarm. Power reduction.
Associated parameter 2.0120.931
Cause
Coolant temperature after engine
too high (limit value 1). Engine
coolant pump failure, volumetric
flow too low, air in engine coolant
circuit.
Corrective action
u Check engine coolant circuit (pressure and flow).
Corrective action
1. Check crank drive:
• Bar engine (→ Page 163).
• Endoscope combustion chambers from bottom dead center to
top dead center.
2. Check air filter for contamination, replace if contamination is
visible (→ Page 186).
3. Check setting of blow-by restrictor valve.
4. Check oil separator condition, replace as necessary (→ Page 165).
