Data Sheet
10.5.1 Fault and Error Propagation
Z-series POL converters protect outputs by triggering either a fault or an error depending on the severity
of the problem (see POL converter datasheets). Fault propagation between POL converters belonging
to the same group is a programmable function of POL converters. The DPM allows propagating faults
and errors between groups of POL converters and, in case of an error, to a DC/DC front-end and an
optional crowbar. The propagation delay for fault/error propagations is less than 10μs.
To enable fault and error propagation, the respective bits needs to be checked in the GUI Fault and
Error Propagation window shown in Figure 16. Note that cross propagation of faults/errors (means fault
in Group X propagates to Y and vice versa) should be avoided.
Figure 16. Fault and Error Propagation Window.
The fault propagation from POL converters to the auxiliary devices can be disabled by checking the bit
in the Auxiliary Device Fault Management window as shown in Figure 17. It is not possible to propagate
a fault from an Auxiliary Device to POL converters.
