INFO
This parameter delays the communication of the new available power to the display unit, CustomLogic, Modbus and other
external components. The controllers in the system immediately know how much power is available and can perform load
sharing immediately once a new genset connects.
Configure the parameter under
Configure > Parameters > Local power management > Delays > P delay after genset connects
.

Delay
0 to 30 s
0 s
The delay is not active for the first genset that connects to a busbar.
7.2.2 Power reservation
The power reservation inputs and parameters are used in the PMS available power calculation for the section. If these inputs and/or
parameters are changed, the changes are broadcast to the rest of the section and also saved in the other controllers in the section.
INFO
Do not specify too much available power. The load-dependent start parameters ensure that the section normally has some
available power.
Secured mode
and
Reserved power
each provide additional available power. Therefore
Secured mode
and
Reserved power
are not normally used simultaneously.
Secured mode
In
Secured mode
, the power management system (PMS) reduces the PMS power available by the nominal power of the largest
connected genset:
Available power = Nominal power - Consumed power - Nominal power of the largest connected genset
You can configure digital inputs so that the operator can easily change secured mode. Configure these inputs under
Configure >
Input/output
.
Function
I/O
Type
Details
Power management > Activate secured
mode
Digital input Pulse
Secured mode is activated in the section when this input is
activated.
Power management > Deactivate secured
mode
Digital input Pulse
Secured mode is deactivated in the section when this input is
activated.
INFO
If there have been conflicting secured mode digital input pulses in a section, then the most recent input is used.
Secured mode digital output
Optional: If you want the controller to activate a digital output when secured mode is activated, then assign the function to a digital
output under
Configure > Input/output
. Select a hardware module with a digital output, then select the output to configure.

For
Reserved power
, the PMS reduces the PMS power available by the reserved power

:
Available power = Nominal power - Consumed power - Reserved power
