Time dependent start/stop
The purpose of the time dependent start/stop function is to be able to start and stop the gen-set
automatically at specific times each weekday or certain weekdays. Auto mode must be activated
for this function. Up to 8 commands can be used for either start or stop. The settings are set up
through the PC utility software. Each command can be set for the following time periods:
•
Individual days (MO, TU, WE, TH, FR, SA, SU)
•
MO, TU, WE, TH
•
MO, TU, WE, TH, FR
•
MO, TU, WE, TH, FR, SA, SU
•
SA, SU
Derate gen-set
The purpose of the derate function is to be able to reduce the maximum output power of the
gen-set, if specific conditions require this. An example of such a condition is the ambient
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:
Input
Engine interface
selection
Analogue input 100 X
VDO input 105 X
VDO input 106 X
Select the needed input in 6260
Pnom 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.
It is necessary to use the PC utility s
oftware when setting up the time dependent
start/stop function.
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 co
nfigured with different minimum
and maximum settings. In this case the settings ‘start derate point’ and
‘slope’ use these new settings.
