Special functions of relays
A special function is normally assigned indirectly. If e. g. a generator “type 2“ has
been set in the “PARGEN“ (3+6) menu, the relay K1 is automatically assigned switch-
ing on the ignition, K2 is assigned the grid contactor of the generator and K5 the
cranking of the generator.
The special functions of the individual relays are in turn activated by setting the re-
spective parameters (701 to 708) to “AUTO“. Only the special function “Operating
state indicator“ can be directly selected with these parameters.
