Functions
• Display unit push-buttons
◦ Change control mode (AUTO & SEMI)
◦ Push-button functions also possible using inputs, PICUS, and/or Modbus
◦ Intuitive, one-touch sequences using the display unit for genset start & stop, and breaker
open & close in SEMI mode
8.2 GENSET controller principles
8.2.1 Configuring a GENSET controller
Configure each GENSET controller in the single-line diagram, using PICUS.
To add a GENSET controller to the single-line diagram:
1. In PICUS, under Configure > Single-line, drag the GENSET icon to the right place on the single-line
diagram.
2. Select the GENSET controller on the single-line diagram, and make sure that its Controller ID is
correct.
3. Broadcast the changes to all the controllers in the system.
• If needed you can override the controller ready status.
8.2.2 GENSET controller nominal settings
The controller nominal settings are used in a number of key functions. For example, many protection settings are based on a
percentage of the nominal settings.
Generator nominal settings
Configure these nominal settings under Configure > Parameters > [Source] > Nominal settings > Nominal settings #, where # is
1 to 4.
Table 8.1
Controller nominal settings
Nominal setting Range Default Notes
Voltage (V) 10 V to 160 kV 400 V The phase-to-phase* nominal AC voltage for the genset.
Current (I) 1 A to 9 kA 867 A
The maximum current flow in one phase (that is, L1, L2 or L3) from the genset
during normal operation.
Frequency (f) 48 to 62 Hz 50 Hz
The system nominal frequency, typically either 50 Hz or 60 Hz. All the
controllers in the system should have the same nominal frequency.
Power (P) 1 kW to 0.9 GW 480 kW The nominal active power may be on the genset nameplate.
Apparent power (S) 1 kVA to 1 GVA 530 kVA The nominal apparent power should be on the genset or generator nameplate.
Power factor (PF) 0.6 to 1 0.9 The power factor should be on the genset or generator nameplate.
*Note: In a single-phase set up the nominal AC voltage is phase-to-neutral.
Configure this under Configure > Parameters > Generator > Nominal settings > Nominal settings # > Calculation method,
where # is 1 to 4:
