Troubleshooting | Contents
Description
The system controller must receive an
"end of charge" feedback signal from the
charger, prior to the Fire order for flashlamp
discharge. If not, a PSU charge error
interlock occurs.
The "end of charge" feedback indicates the
PFN capacitor has charged to the desired
voltage.
This interlock indicates that the Pulse
Forming Network (PFN) capacitor voltage
actual value exceeds the programmed
voltage by 5% or more.
The flashlamp simmer current is constantly
monitored. If the simmer current fails to
establish or "blows out", then this interlock
is activated.
