570 – L1 AI CAN Max Retarded Timing
Yellow alarm.
Associated parameter 2.1200.931
Cause
Corrective action
The cylinder set to maximum
retarded timing due to knocking
has violated the first limit value.
1. Check emissions.
2. Check ignition timing (→ Page 154).
3. Check combustion chamber.
4. Check gas quality if feasible (methane number).
571 – L2 AI CAN Max Retarded Timing
Yellow alarm. Power reduction.
Associated parameter 2.1200.932
Cause
Corrective action
The cylinder set to maximum
retarded timing due to knocking
has violated the second limit
value. Power reduction is initiated.
1. Check emissions.
2. Check ignition timing (→ Page 154).
3. Check combustion chamber.
4. Check gas quality if feasible (methane number).
572 – L3 AI CAN Max Retarded Timing
Red alarm. engine shutdown.
Associated parameter 2.1200.933
Cause
Corrective action
The cylinder set to maximum
retarded timing due to knocking
has violated the third limit value.
1. Check emissions.
2. Check ignition timing (→ Page 154).
3. Check combustion chamber.
4. Check gas quality if feasible (methane number).
583 – AL Circuit Breaker Closed
Red alarm. engine shutdown.
Associated parameter 2.0451.115
Cause
Corrective action

open when engine stops. Engine
is motoring.
1. Check generator load switch.
2. Disconnect generator switch manually.
3. Open mains circuit breaker if applicable.
4. Do not actuate manual emergency off if possible.
617 – LO Actual Value Hu
Yellow alarm.
Associated parameter 2.1210.006
Cause
Corrective action
Fuel calorific value has undershot
the first limit value
u
Check gas quality if feasible.
