Validity

Column

Explanation

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

Fault

Event of type »Fault« The genset is shut down immediately.

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

Fault SC

Event of type »Fault SC« The genset is stopped by controlled shutdown. Refer to »Function »Function Fault Fault SC« on page 5.

Alarm

Event of type »Alarm«. »Alarm «. The alarm is recorded as a note in the operation log.

Alarm RP

Event of type »Alarm »A larm RP« The permitted power is reduced by 20%, based on the maximum power. The alarm is recorded in the operation log. Refer to »Function »Function Alarm Alarm RP« on page 5.

Notes 1.2.1

Function Fault SC

ower

Load run

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

set permitted p a r a m e t e r i s e d r a m p

When a »Fault SC« appears the admissible power is immediately set to the current actual power. Thus a further increase of the power is prevented. After expiration of the delay time (e.g. 5 minutes) the admissible power is reduced to 0.0 %. The set power follows the admissible power to a parameterisable 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 deselected. Note

If all faults of type »Fault SC« can be acknowledge in the operation log during the shut down process, the power is increased again to the externally demanded power and the load run is continued.

Shutdown

5 minutes Fault SC

Figure 1: 1.2.2

Time

Controlled shutdown of the genset with a »Fault SC« Function Alarm RP

»Alarm RP« events are logged as »Alarm« in the operation log. Additionally, the permitted power is reduced by 20%, based on the maximum power. The power reduction is marked in the operation log by the alarm »Power reduction to safe power«.

Idle mode

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