Maximum positive deviation of one cylinder temperature from the average at the PminCylDifEval load. Alarm 
can be activated depending on Block type (set in GenConfig ->Software configuration->Analog inputs) – all 
the time or after some time after start (depends on RunOnlyBlkDelX time). 
Step:     1 °C 
Range:    ± 32000 °C 
Max-CylDifPmin    [ °C ]  
Max-CylDifPmin  = Maximum negative Cylinder temperature Difference at minimal gen-set Power level. 
Maximum negative deviation of one cylinder temperature from the average at the PminCylDifEval. load. 
Alarm can be activated depending on Block type (set in GenConfig ->Software configuration->Analog inputs) 
– all the time or after some time after start (depends on RunOnlyBlkDelX time). 
Step:     1 °C 
Range:    ± 32000 °C
 
Max+CylDifPnom     [ °C ] 
Max-CylDifPnom  = Maximum positive Cylinder temperature Difference at nominal gen-set Power level. 
Maximum positive deviation of one cylinder temperature from the average at the Nomin power. Alarm can be 
activated depending on Block type (set in GenConfig ->Software configuration->Analog inputs) – all the time 
or after some time after start (depends on RunOnlyBlkDelX time).
 
Step:     1 °C 
Range:    ± 32000 °C 
 
 
 
 
Max-CylDifPnom     [ °C ]  
Max-CylDifPnom  = Maximum negative Cylinder temperature Difference at nominal gen-set Power level. 
Maximum negative deviation of one cylinder temperature from the average at the Nomin power. Alarm can 
be activated depending on Block type (set in GenConfig ->Software configuration->Analog inputs) – all the 
time or after some time after start (depends on RunOnlyBlkDelX time).

PminCylDifEval      [ kW – MW* ] 
Minimum gen-set Power for Cylinder temperature Difference evaluation. The protection is not evaluated, if 
the gen-set power is lower than this limit. 
Step:   0,1 kW / 1 kW / 0,01 MW* 
Range:   0,0 kW –  Nominal power* 
*Note:
 
The actual setpoint units and range depend on setting of the Power format (see GenConfig manual). 
CylDifEvalDel       [ s ] 
Cylinder temperature Difference Evaluation Delay. 
Step:     1s 
Range:   0 – 600 s 
Cylinder temperature deviation protection type: warning
