Emergency Run

General notes
244
The emergency power operation is possible only in
application mode
If the LogicsManager outputs 'Stop request in AUTO'
or 'Inhibit emergency run' are TRUE, an emergency
power operation may be prevented or interrupted from
an external source.
Prerequisites
The emergency power function can only be acti‐
–
vated for synchronous generators with parameter
2802 Ä p.
Emergency power is carried out in operating mode
–
AUTOMATIC regardless of the status of the Logi‐
csManager output 'Start request in AUTO' (Logi‐
csManager).
The display indicates "Emergency run" during emergency power
operation.
The following principles are observed in case of an emergency
power operation:
If an emergency power operation is initiated, the engine is
n
started automatically, unless the start sequence is interrupted
via an alarm or prevented via the LogicsManager or the oper‐
ating mode is changed.
The GCB can be closed regardless of the engine delay time if
n
the generator frequency and voltage are within the configured
operating limits (
Voltage / Frequency" on page 107 ) if the parameter "Undelay
close GCB" (parameter
ingly (default setting).
If the mains return during an emergency power operation (GCB
n
is closed), the mains settling time (parameter
must expire before the load is transferred from the generator to
mains operation.
Activation of emergency power
If the mains are not within the configured frequency
and voltage operating limits (Ä Chapter 4.4.2.1 "Mains
Operating Voltage / Frequency" on page 136) for at
least the time configured in the parameter "Mains fail
delay time" (parameter
power operation is activated.
MCB malfunction
An emergency power operation will be performed, if
the control is not able to close or recluse the MCB and
the alarm "Fail to close MCB" occurs.
