Restrictions on Use
The load short-circuit protection function only protects internal circuits for a short period.
As shown in the figure above, the load short-circuit protection of this NX Unit is automatically
released when the Tj equals to Tr.
Therefore, unless the cause of short-circuit is removed, ON/OFF operations are repeated in the out-
put.
If the short-circuit is not corrected, output elements deteriorate. If any external load is short-circuited,
immediately turn OFF the applicable output and remove the cause of the short-circuit.
