Function I/O Type Details
power management system (PMS) reserves 100 % of the power
required for the heavy consumer at the busbar.

Required if Variable is selected for Feedback type .
For example, this can be connected to a power transducer with a 4 to
20 mA output, and configured so that 4 to 20 mA corresponds to 0 to
100 % of the heavy consumer nominal load. if the heavy consumer
nominal load is 500 kW, but the heavy consumer is only using 200
kW, the power transducer output is 4 mA + (200 kW / 500 kW × 16
mA) = 10.4 mA.
Alternatively, the analogue input may be configured for another type of
input, or another input range.
*Note: By default [Heavy consumer #] is HC #, where # represents the System ID . [Heavy consumer #] can be replaced with the
Controller label entered in the single line diagram for the heavy consumer.

Load [%]*
Analogue
output
0 to 100 % of the heavy

load
The controller outputs the actual heavy consumer load, as
a percentage of the heavy consumer nominal load. For this
to work, you must configure an analogue input with
[Heavy
consumer #] > Feedback .

Load [kW]*
Analogue
output
0 kW to 9 GW
The controller outputs the actual heavy consumer load. For
this to work, you must configure an analogue input with
[Heavy consumer #] > Feedback .
*Note: By default [Heavy consumer #] is HC #, where # represents the System ID . [Heavy consumer #] can be replaced with the
Controller label entered in the single line diagram for the heavy consumer.
Parameters
The parameters are only visible in the controller to which the heavy consumer is assigned. By default [Heavy consumer #] is HC #,
where # represents the
System ID . [Heavy consumer #] can be replaced with the Controller label entered in the single line diagram
for the heavy consumer.
Configure these parameters under Configure > Parameters > Heavy consumers > [Heavy consumer #] > Nominal settings ,
where # is 1 to 4.

Parameter Range Default Comment
Initial load 100 to 500 % 125 %
The available power required in the system (as a percentage of the heavy consumer
nominal load) for the PMS to activate the heavy consumer acknowledge.
Use this parameter to allow a high connection current.
Nominal load 0 kVA to 1 GVA 100 kVA The heavy consumer nominal load.
Power factor 0.6 to 1.0 0.9 The heavy consumer power factor.
Configure this parameter under Configure > Parameters > Heavy consumers > [Heavy consumer #] > Acknowledge , where # is
1 to 4.
