7.1.6 Section power management
For each controller, you can configure parameters for the section power management rules. You can use up to eight sets of power
management rules.
By default, all controllers use
Power management rules 1
. When the power management rules are changed for one controller, then
all the controllers in the section automatically use the same power management rules.
You can use CustomLogic to assign a set of power management rules to a controller, based on the operating conditions.
Alternatively, you can configure a digital input to activate a specific set of power management rules.
Inputs and outputs
Assign the input and output functions under
Configure > Input/output
. Select the hardware module, then select the input/output to
configure.

management rule
Digital
input
Continuous
When this input is activated, the controller uses the same power
management rules as the other controllers in the section are using. When
activated, this input overrides any set of power management rules
required by the controller's CustomLogic or a digital input.
Power management >
Activate power management
rule #, where # is 1 to 8
Digital
input
Continuous
The controller starts using the specified set of power management rules
when this input is activated. As a result, the other controllers in the
section also start using the specified set of power management rules.
You can create a power management rule conflict in the section if this
input function is active in two controllers for two different sets of power
management rules at the same time. A conflict activates the
Different
power management rules activated
alarm, and forces all the controllers in
the section to switchboard control.
Power management >
Power management rule #
active, where # is 1 to 8
Digital
output
Continuous
The controller activates this relay when the controller is using the
specified set of power management rules.
Parameters
The parameters are configured under
Configure > Parameters > Power management rules > Configuration #
, where # is 1 to 8.
More information
The descriptions for the power management rules parameters are included in various topics in this chapter.
Power management rules within a section
All controllers in a section must use the same power management rules at the same time. If different power management rules are
assigned to two or more controllers in the section, then the controllers activate the
Different power management rules activated
alarm.
Bus tie breaker example
Two sections may each use their own set of power management rules when the bus tie breaker between them is open.
The sections must use the same set of power management rules when the bus tie breaker is closed.
Power management rules when splitting a section
The power management system (PMS) uses the section's power management rules when splitting a section. The PMS does not try
to anticipate what the power management rules will be after the split.
