The outputs are protected against:
Polarity reversal (24 V DC)
D
Short−circuit
D
Overload.

In all these cases, the LED error indicator lights. In case of a short−circuit
or overload the respective output is deactivated. After 2 ms the output is
reactivated. If the short−circuit is still present, the output is deactivated
again after 40 ms. This process is repeated after 2 ms.
The following table shows that the simultaneity factor when driving the
outputs is dependent on ambient temperature and on the use of a fan
unit.
