6.2 Fault messages in genset control system log
112222 – HI T-Exhaust Mean
Yellow alarm. Initiated by EMU.
Cause
Corrective action
Weighted average of all individual
exhaust gas temperatures is too
high.
1. Check emission values (→ Page 46).
2. Check ignition timing (→ Page 175).
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 individual
exhaust gas temperatures is too
high.
1. Check emission values (→ Page 46).
2. Check ignition timing (→ Page 175).
3. Check valve drive (exhaust valves do not close).
112301 – HI T-Exhaust A1
Yellow alarm. Initiated by EMU.
Cause
Corrective action
Individual exhaust gas
temperature of this cylinder is too
high in comparison with weighted
average.
1. Check emission values (→ Page 46).
2. Check ignition timing (→ Page 175).
3. Check valve drive (exhaust valves do not close).
112302 – HI T-Exhaust A2
Yellow alarm. Initiated by EMU.
Cause
Corrective action
Individual exhaust gas
temperature of this cylinder is too
high in comparison with weighted
average.
1. Check emission values (→ Page 46).
2. Check ignition timing (→ Page 175).
3. Check valve drive (exhaust valves do not close).
112303 – HI T-Exhaust A3
Yellow alarm. Initiated by EMU.
Cause
Corrective action
Individual exhaust gas
temperature of this cylinder is too
high in comparison with weighted
average.
1. Check emission values (→ Page 46).
2. Check ignition timing (→ Page 175).
3. Check valve drive (exhaust valves do not close).
