Pin 415: Manual return transfer
This command prevents automatic return transfer of source II to source I. In other words,
even if source I is available again, the 3KC8 transfer switching equipment remains in switch
position II and must be switched back manually. The command becomes active when
contacts 415 and 417 are closed.
If the contact is opened, the transfer switching equipment changes to switch position I after
expiry of the set delay times (higher priority due to network/generator application) when
source I is available again.
Pin 416: Inhibition of automatic mode
This command inhibits the automatic mode of the electronic module without activating
another operating mode. In this way, the 3KC8 transfer switching equipment can be
operated only in manual operation (using the handle) or in remote mode (using inputs 313-
317 on the motor operator).
Pin 417: Common control terminal of inputs 413-416
Pin 417 is used as the common control terminal for inputs 413-416.
