The Model 9106 (DDM) front panel shown in Figure 3-3 contains a FAULT indicator and four output test points.
The FAULT illuminates when one or more of the four outputs fail. The FAULT indication is latched until cleared
by “FAULT RESET” switch on the front panel of the FSU. The output test points allow monitoring of selected
outputs from the front panel.
