Impulse logic
The figure below shows an example for the control logic of the 3KC3 transfer switching equipment in the case of impulse logic:
The 3KC3 transfer switching equipment is switched to a position by an impulse and remains in this position until a new impulse occurs:
-
A switching command must be active for longer than 60 ms for the transfer switching equipment to switch.
-
The switching command to position I and the switching command to position II have a higher priority than the switching command to position 0. If the switching command to position I is issued at the same time as the switching command to position II, the transfer switching equipment remains in the current position, as the switching command is ignored.
-
To select impulse logic, inputs 313-317 (switch position 0) must not be continuously closed.
The following accessories can be used to activate impulse logic:
![]() 3 x pushbuttons, 3SU1000-0AB10-0AA0, and 3 x holders, 3SU1500-0AA10-0AA0
|
![]() 3 x contact blocks with one contact element, 3SU1400-1AA10-1LA0
|
NOTE
Contact blocks with gold-plated internal contacts must be used.
