General block mode description
When the block mode is selected, the unit is locked for certain actions. This means that it cannot
start the gen-set or perform any breaker operations.
To change the running mode from the display, the user will be asked for a password, before the
change can be made. It is not possible to select ‘block mode’, when running feedback is
present.
Short time parallel is ignored in test mode.
Test mode cannot be used, if the gen-set is in island operation (gen-set mode
selected to island mode).
It is not possible to open and close the generator breaker or the mains breaker
in manual mode.
It is necessary to configure the digital inputs through the PC utility software to
use the manual commands. The number of configurable digital inputs is option

MAN mode cannot be selected, when AUTO mode is selected. To go from AUTO
to MAN it is necessary to go to SEMI-AUTO to make MAN available.
