INFO
The values in menu 7050 set the cos phi. This is not the PF value displayed in the display. Cos phi and PF are only equal if
it is a true sinusoidal wave.

2.4.8 Warm up ramp
Warm up ramp is a function that limits the power output until a pre-configured condition has been met, like, for example, the engine
has reached operating temperature which will greatly reduce stress on the engine.

The warm up ramp activation is enabled and the input is configured via Warm up type (parameter 2961). The activation of the warm
up ramp input limits the available power of the genset to the percentage level configured in Power ramp up (parameter 2612).
If the type is configured as M-Logic, the input must go low before warm up ramp is deactivated. If the type is configured as a multi-
input or an EIC temperature input, the deactivation occurs when the temperature is above the threshold configured in Warm up
thresh. (parameter 2962).
INFO
When warm up ramp is activated, the standard function Power ramp up is replaced, which means that the load/steps and
the timer are disabled.
2.4.9 Peak shaving
Auto mode description
The genset will start at a pre-defined mains import level and run at a fixed minimum load, for example 10 %. When the mains import
increases above the maximum mains import set point, the genset will supply the extra load in order to maintain the mains import at
the maximum import level.
When the load drops below the maximum mains import set point, the genset will run at minimum load again. When the mains import
and the generator load decrease below the stop set point, the genset will cool down and stop.
