WARNING
Before acknowledging the short-circuit diagnosis, remedy the respective error and validate
your safety function. To do this, proceed as described in chapter "
Fault Diagnostics
(Page

Always Shutdown due to
violation of upper or
lower temperature limit

case
Check load wiring, check ambient
temperature, check whether permissible
output current is exceeded for the
ambient temperature. Once the fault has
been eliminated, the module must be
removed and inserted or the power
switched off and on.
