Output behaviour if overload/short circuit
occurs the FC30/FC34
Transistor outputs A0.2 to A0.7 are indepen-
dently protected against short circuits and
overloads.
If short circuit or overload current is applied,
the switching transistor heats up. The over-
heating fuse switches the output concerned
off, meaning that the switching transistor can
cool down again. Subsequently the output con-
cerned is reactivated. If overload current is still
present after reactivation, the process starts
again from the beginning.
The process cycle time depends on the magni-
tude of the load. If there is only a minimal
overload, the cycle time can be up to several
minutes, and if there is a major overload this
time may be less than 1 second.
