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

When this input is activated, the controller changes the parameter
value under Configure > Parameters > Local power management

enabled.
Parameters
Configure the following parameters under Configure > Parameters > Local power management > Asymmetric load sharing > Q
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 Q load sharing is active for the GENSET controller. The
power management system runs the genset(s) with asymmetric Q load sharing
enabled at their set points while the remaining genset(s) supply a load that is
between the asymmetric Q load sharing Minimum and Maximum. If more than
one genset has asymmetric Q load sharing enabled, then the genset with the
highest priority also has the highest asymmetric Q load sharing priority.
• Not enabled: The GENSET controller shares the load equally with the other
GENSET controllers. If other GENSET controllers have asymmetric Q load
sharing enabled, then the GENSET controller without asymmetric Q load
sharing shares the load equally with the other gensets without asymmetric Q
load sharing.

Parameter
The controller only uses these parameters when asymmetric Q load sharing is
enabled.
• Parameter: The controller uses the Set point parameter as the set point for
asymmetric Q load sharing.
• External: The controller uses the analogue input with Local power
management > Asymmetric load sharing > Q set point [%] as the set point for
asymmetric Q load sharing.
• External -> Off: This is used if the asymmetric Q load sharing set point from
an analogue input fails. That is, when the input for Local power management >
Asymmetric load sharing > Q set point [%] is outside the configured scale. If
the external set point fails, then the controller turns off asymmetric Q load
sharing.
• External -> Parameter: This is used if the asymmetric Q load sharing set point
from an analogue input fails. That is, when the input for Local power
management > Asymmetric load sharing > Q set point [%] is outside the
configured scale. If the external set point fails, then the controller ignores the
