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 cylinder
exhaust gas temperatures is too
high.
1. Check emission values (→ Page 47).
2. Check ignition timing (→ Page 176).
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 47).
2. Check ignition timing (→ Page 176).
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 47).
2. Check ignition timing (→ Page 176).
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 47).
2. Check ignition timing (→ Page 176).
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 47).
2. Check ignition timing (→ Page 176).
3. Check valve drive (exhaust valves do not close).
112304 – HI T-Exhaust A4
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 47).
2. Check ignition timing (→ Page 176).
3. Check valve drive (exhaust valves do not close).
