Set
The nominal value of engine rpm. Low-
1500 high rpm limits are defined by reference
to this value.
When secondary frequency is selected,
this is the nominal value of engine rpm.
1800
Low-high rpm limits are defined by
reference to this value.
When tertiary frequency is selected, this
is the nominal value of engine rpm.
1800
Low-high rpm limits are defined by
reference to this value.
If the engine rpm goes under this limit
R-10% when feeding the load, this will generate
a GENSET LOW RPM warning.
If the engine rpm goes under this limit
when feeding the load, this will generate
R-15%
a GENSET LOW RPM shutdown alarm
and the engine will stop.
If the engine rpm goes over this limit
when feeding the load, this will generate
a GENSET HIGH RPM warning.
If the engine rpm goes over this limit
when feeding the load, this will generate
a GENSET HIGH RPM shutdown alarm
and the engine will stop.
If the engine rpm goes outside of the
3 limits during this timer, an engine speed
fault will occur.
If the engine rpm goes over the "High
RPM Shutdown Limit" by this quantity,
HRSL
this will generate immediately a GENSET
+10%
HIGH RPM shutdown alarm and the
engine will stop.
0: speed signal existency not checked
1: If the speed signal is lost, it will
0 generate a Speed Signal Lost fault
condition. The action taken upon fault
condition is programmable.
0: shutdown alarm
0 1: loaddump alarm
2: warning
If the speed signal is lost during this
0 timer, a Speed Signal Lost fault will
occur.
If the charge alternator voltage goes
6.0 under this limit, a charge alternator
voltage warning will occur.
If the charge alternator voltage goes
under this limit, a charge alternator
4.0
voltage shutdown will occur and the
engine will stop.
