Front Panel
Figure 3 shows the physical features of the isolated Guarded
output module. The front panel of the module contains a
module active and fault status indicator, a shutdown
indicator, as well as output fuses, output status indicators and
blown fuse indicators for the output circuits.
Active/Fault Status Indicators
These green and red LEDs indicate the overall health of the
module and output circuits. During normal operation, the
green ACTIVE indicator flashes at the controller's scan rate.
If a module fault is detected, the red FAULT indicator turns
on and the green ACTIVE indicator turns off.
