Table 8.5: 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
switching 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.
If a relay has been assigned both a battery state-dependent control and
a special function, only the special function is performed!
The relays are controlled by the Sunny Island in regular operation only. If
the Sunny Island is switched into standby mode, the AC voltage is miss-
ing or an error state occurs, all relays are dropped out after a short pe-
