The following diagram depicts all the required connections to
implement an entire system fault group. An external Panic
Switch is included in the diagram to define the
interconnections for an operator commanded shutdown. In
this application, the Panic Switch shall allow all interconnected
modules to follow the function of the switch. Since no fault has
been reported, the user may use this feature to command all
power modules off.
An external Interlock Switch is shown connected to the
Remote Inhibit pins of the Controller module to prevent turning
on power module outputs until conditions are safe. Finally, the
Discrete Fault Indicator (DFI) and Power On (PWR ON) output
signals of the Controller are shown illuminating indicators in
the user space.
