Derate limit
( 6260 P
nom
derate):
This is the lowest derate level.
Derate characteristic
It can be selected whether the characteristic of the derating should be proportional or inverse
proportional. The drawing above shows the inverse characteristic.
The proportional characteristic is illustrated below.
The gen-set is derated when the control value is lower than the set point (in the example above
the control value is an mA signal).
The derate characteristic is selected in
6260 Pnom derate
.
Setting OFF: Inverse characteristic
Setting ON: Proportional characteristic
