Name Details
DEIF network The DEIF network is used for asymmetric P load sharing.
GOV control The controller must control the genset governor for active power load sharing.
Control types
For controllers under power management system control (that is, in AUTO or SEMI mode), if enabled, the power management
system uses asymmetric P load sharing to share the load between the connected equipment. The shared load may be the total
system load. However, if a connected controller is under switchboard control, or if the SHAFT generator controller is supplying a
base load, then the shared load is the remaining load.
If a controller is under switchboard control, then that controller does not control its load, and therefore it cannot participate in load
sharing.
Input
If required, assign input functions under Configure > Input/output. Select the hardware module, then select the input to configure.

is Enabled and Source is External, then the controller uses this
analogue input as the set point for asymmetric P load sharing.

Digital input Pulse
When this input is activated, the controller changes the parameter
value under Configure > Parameters > Local power management
> Asymmetric load sharing > P configuration > Enable to Not
enabled.
Parameters
Configure the following parameters under Configure > Parameters > Local power management > Asymmetric load sharing > P
configuration.
These parameters only apply to the selected GENSET controller. Other GENSET controllers can have different parameters.
Parameter
Range Default Notes
Enable
• Enabled
• Not enabled
Not enabled
• Enabled: Asymmetric P load sharing is active for the GENSET controller. The
power management system runs the genset(s) with asymmetric P load sharing
enabled at their set points while the remaining genset(s) supply a load that is
between the asymmetric P load sharing Minimum and Maximum. If more than
one genset has asymmetric P load sharing enabled, then the genset with the
highest priority also has the highest asymmetric P load sharing priority.
• Not enabled: The GENSET controller shares the load equally with the other
GENSET controllers. If other GENSET controllers have asymmetric P load
sharing enabled, then the GENSET controller without asymmetric P load
sharing shares the load equally with the other gensets without asymmetric P
load sharing.

Parameter
The controller only uses these parameters when asymmetric P load sharing is
enabled.
