the output switch's ability to conduct current (through an
internal dummy load). If current is conducted, the fault is in
the load. If no current is conducted, the fault is in the output
switch circuit. Healthy outputs commanded to be on but not
wired to an external load will always cause an open load
condition to be displayed.
Front Panel
Figure 2 shows the physical features of the AC Guarded
output modules. The front panel contains an active and fault
status indicator, a diagnostic message display, as well as
status indicators and fuses for each output circuit.
Active/Fault Status Indicator
These green and red LEDs indicate the overall health of the
module and its field circuits. During normal operation, the
green ACTIVE indicator flashes at the controller’s scan rate.
If a module fault occurs the red FAULT indicator turns on
and the green ACTIVE indicator turns off.
Output Status Indicators
The output status indicators are yellow LEDs, located on the
field side of the output circuit, in parallel with the load. These
indicators are on when the load is energized.
