153231 – HI Knock Integrator B1
Yellow alarm. Initiated by SAM.
Cause
Corrective action
Readjustment of ignition timing
beyond a limit value because
knocking was detected in this
cylinder.
1. Check emission values.
2. Check ignition timing (→ Page 154).
3. Check combustion chamber.
4. Check gas quality if feasible (methane number).
153232 – HI Knock Integrator B2
Yellow alarm. Initiated by SAM.
Cause
Corrective action
Readjustment of ignition timing
beyond a limit value because
knocking was detected in this
cylinder.
1. Check emission values.
2. Check ignition timing (→ Page 154).
3. Check combustion chamber.
4. Check gas quality if feasible (methane number).
153233 – HI Knock Integrator B3
Yellow alarm. Initiated by SAM.
Cause
Corrective action
Readjustment of ignition timing
beyond a limit value because
knocking was detected in this
cylinder.
1. Check emission values.
2. Check ignition timing (→ Page 154).
