Trip Reset
When false, the faults are latched permanently and the healthy output remains inactive after
changing the start input (C3) Off/On. The trip reset must then be set to true for the faults to be reset
and the healthy output to go active (high) when C3 goes low. this feature can be used in
applications where you want to reset the faults under your own control, rather than automatically
with the start/run command.
Range: 0 : False
