Configuring Load-Dependent Start/Stop Isolated Operation
Additional assumptions are valid for isolated operation (IOP), i.e. in case of an emergency operation:
• A reserve power of 80 kW on the busbar shall be maintained, i.e. at least 2 generators are available in iso-
lated operation for redundancy because no supporting mains are present.
• A hysteresis of 20 kW is required to avoid frequent starts and stops.
• The delay for adding another generator shall be 10 seconds.
• The delay for adding another generator shall be reduced to 3 seconds if a generator at the busbar is operating
above its rated load (accelerated start of the next generator).
• The delay for removing a generator from the busbar shall be 180 seconds.
From the main screen on the unit select Parameter -> Configuration -> Application config. -> Automatic run con-
fig. -> Load dependent start/stop -> Isolated operation and configure the following parameters:
ID Parameter Value Comment
5760 IOP Reserve power 80 kW The reserve power in isolated operation is 80 kW
5761 IOP Hysteresis 20 kW The reserve power hysteresis in isolated operation is 20 kW
5764 IOP Add on delay 10 s The add on delay in isolated operation is 10 seconds
5765 IOP Add on delay at rated load 3 s The add on delay at rated load in isolated operation is 3 seconds
5766 IOP Add off delay 180 s The add off delay in isolated operation is 180 seconds

Configuring Load-Dependent Start/Stop Mains Parallel Operation
Additional assumptions are valid for mains parallel operation (MOP):
• The first generator is only started if it is able to operate at a minimum load of 40 kW.
• A hysteresis of 20 kW is required to avoid frequent starts and stops.
• A reserve power of 10 kW on the busbar shall be maintained, i.e. at least 10 kW of generator capacity are
available for short load peaks. Higher load peaks are supported by the mains.
• The delay for adding another generator shall be 30 seconds.
• The delay for adding another generator shall be reduced to 10 seconds if a generator at the busbar is operat-
ing above its rated load (accelerated start of the next generator).
• The delay for removing a generator from the busbar shall be 60 seconds.
From the main screen on the unit select Parameter -> Configuration -> Application config. -> Automatic run con-
fig. -> Load dependent start/stop -> Mains parallel operation and configure the following parameters:
ID Parameter Value Comment
5767 MOP Minimum load 40 kW The minimum load in mains parallel operation is 40 kW
5769 MOP Hysteresis 20 kW The reserve power hysteresis in mains parallel operation is 20 kW
5768 MOP Reserve power 10 kW The reserve power in mains parallel operation is 10 kW
5772 MOP Add on delay 30 s The add on delay in mains parallel operation is 20 seconds
5773 MOP Add on delay at rated load 10 s The add on delay at rated load in mains parallel operation is 10 seconds
5774 MOP Add off delay 60 s The add off delay in mains parallel operation is 60 seconds
