del. Protection is indicated by message Vb LX over (X = number of corresponding phase) or Vb
LX under. When Basic settings:FixVoltProtSel is adjusted to PHASE-PHASE then this
protection is evaluated based on voltage between phases and it is indicated by “Vb LXY over”
or “Vb LXY under” (where XY are number of corresponding phases)
Bus Over and Under Frequency: This protection limits are given by setpoints Bus protect:Bus >f,
Bus protect: Bus <f. Delay for over and under frequency is given by the setpoint Bus
protect:Bus f del. Protection is indicated by message “fbus fm over” or “fbus fm under”.
8.1.6 User configurable protections
Controller provides vast possibilies for user configurable protections. There are several protections

archive.
Mains Current Unbalance: This protection is by default configured as Mains protect with indication
“Mains I unbal”. For more information on this protection see the Protections tab in default
archive.
Bus Voltage Unbalance: This protection is by default configured as HistoryRecOnly with indication
“Bus V unbal”. For more information on this protection see the Protections tab in default archive.
Battery Over and Under Voltage: There are two protections configured by default as Warnings with
indication “Batt volt”. For more information on this protection see the Protections tab in default
archive.
8.1.6.2 Configuration of User configurable protections in GenConfig
It is possible to configure protections on Binary Input, Analog Input or any value that is available in the
controller.
8.1.6.2.1 Binary Input protection configuration
Open I/O tab in GenCofig and adjust parameters that are described below.
Enable/Disable protection for this input
Name of the binary input is also
used as the name of the protection
Type of protection
Toggle normally closed/normally open
Defines when the protection is active
Defines protection delay
8.1.6.2.2 Analog Input protection configuration
Open I/O tab in GenCofig and adjust parameters that are described below.
