1.1 Validity

This list of limit values is only valid for gas engines disbributed by MWMequipped with the TEM-Evo-System. It is only suitable for the engine type ind-cated on the front page.

The list of limit values is valid for the following software release until a new listof limit values will be published.

2.50.04 CPU-P

1.2 Design of the List of Limit values

1.2.1 Function Fault SC

Load run

During load run (mains parallel mode) a fault of the type Fault SC causes thecontrolled shutdown of the genset.

When a Fault SC appears the admissible power is immediately set to thecurrent actuall power. Thus a further increase of the power is prevented.

After expiration of the delay time (e.g. 5 minutes) the admissible power is re-

duced to 0.0 %. The set power follows the admissible power to a parameteris-able ramp.

Setting of the delay timet:Parameter 10033 Delay time fault SC

Specification of the ramp for the set power:Parameter 23007 Power control set ramp controlled shutdown

In case that the value of the actual power is below 10 %, the genset is dese-

lected.Note

If all faults of type Fault SC can be acknowledge in the operation log duringthe shut down process, the power is increased again to the externally demand-ed power and the load run is continued.

Idle

If the genset is not operated in load run, every fault of type Fault SC causesthe immediate shutdown of the genset. With a pending Fault SC a start ofthe genset or the idling operation are impossible.

Figure 1: Controlled shutdown of the genset with Fault SC

1.2.2 Function Alarm (LR)

Events of type Alarm (LR) are intered in the operation log as an alarm. Ad-ditionallz, the admissible power is restricted to maximally 80 %. The power re-duction is marked in the operation log by the alarm Power reduction to safepower.
