temperature. If the ambient temperature increases to a level where the cooling water coolers
decrease in cooling capacity, it will be necessary to reduce the power of the gen-set.
If the gen-set is not derated, alarms and shutdown events will very likely occur.
Input selection
The derate function can be configured to one of the following inputs:
Engine interface
selection Input
M1 M2
Analogue input 100 X X
PT100 input 106 X
PT100 input 109 X
VDO input 105 X
VDO input 106 X
Select the needed input in
6260 P
nom
derate
.
Derate parameters
The parameters that define the derate characteristics are the following:
Start derate point (
6260 P
nom
derate
):
This is the setting where the derating must start. The setting can be in mA (max. 20mA) or
in centigrades ºC (max 200ºC).
Slope (
6260 P
nom
derate
):
Adjust the derating speed. The adjustment is in percent per unit, i.e. if the 4…20mA input is
used (analogue 100), then the derating will be in %/mA, and if the PT100/VDO input is
used, then the derating will be in %/C.
The derate function is typically used when cooling problems are expected.
Refer to the type label for information about engine interface selection.
Be aware that the 4…20mA input can be configured with different minimum
and maximum settings. In this case the settings ‘start derate point’ and
‘slope’ use these new settings.
