7.2 Fault messages in genset control system log
Possible engine responses to yellow alarm:
Warning, power limitation/reduction, speed limitation, engine stop
Possible engine responses to red alarm:
Engine stop, power limitation/reduction, speed limitation, warning
Procedure following an automatic safety shutdown (→ Page 52)
112222 – HI T-Exhaust Mean
Yellow alarm. Initiated by EMU.
Cause
Corrective action
Weighted average of all cylinder
exhaust gas temperatures is too
high.
1. Check emission values (→ Page 57).
2. Check ignition timing (→ Page 186).
3. Check valve drive (exhaust valves do not close).
112223 – HIHI T-Exhaust Mean
Red alarm. Initiated by EMU.
Cause
Corrective action
Weighted average of all cylinder
exhaust gas temperatures is too
high.
1. Check emission values (→ Page 57).
2. Check ignition timing (→ Page 186).
3. Check valve drive (exhaust valves do not close).
112301 – HI T-Exhaust A1
Yellow alarm. Initiated by EMU.
Cause
Corrective action
Exhaust gas temperature of this
cylinder is too high in comparison
with weighted average.
1. Check emission values (→ Page 57).
2. Check ignition timing (→ Page 186).
3. Check valve drive (exhaust valves do not close).
112302 – HI T-Exhaust A2
Yellow alarm. Initiated by EMU.
Cause
Corrective action
Exhaust gas temperature of this
cylinder is too high in comparison
with weighted average.
1. Check emission values (→ Page 57).
2. Check ignition timing (→ Page 186).
3. Check valve drive (exhaust valves do not close).
112303 – HI T-Exhaust A3
Yellow alarm. Initiated by EMU.
Cause
Corrective action
Exhaust gas temperature of this
cylinder is too high in comparison
with weighted average.
1. Check emission values (→ Page 57).
2. Check ignition timing (→ Page 186).
3. Check valve drive (exhaust valves do not close).
