Global defines for fault-monitor related parameters.

This section is used to define power supply fault object timing settings. The fault monitor is continuously monitoring declared data objects at the high-priority task frequency defined by MAIN_EXECUTION_PERIOD. Based on this known interval, filtering delays for fault trip and fault recovery events to allow users to adjust the fault detection sensitivity.

Fault Trip Event Delay
This setting defines for how long a fault condition has to be continuously active before the effective fault trip status/event will be triggered.
Fault Recovery Event Delay
This setting defines for how long a fault condition has to be continuously cleared before the effective fault recovery status/event will be triggered.
Restart Cycle Limit In case of a persistent fault condition (e.g continuous short circuit or unstable feedback loop) the fault monitor will limit the number of restart attempts specified by FAULT_RESTART_CYCLES. When this threshold is exceeded, the power supply will latch in save state (off) and a CPU or power cycle is required to start-up the power supply again. under voltage lock out trip delay in [sec]
