5 AC 800F Functional Description
5-2
All indicators and operating elements of the AC 800F CPU are located on the front
panel of the power supply module.
The operating system controls the colors of
the Failure, Run/Stop and Prim/Sec LEDs.
Refer to Section 5.3 for details.
The Reset switch is recessed to avoid
unwanted actuation by accident. It can only
be pressed by using a "tool" like a ball pen or
similar. No tool is required for actuating the
Toggle switch and the Run/Stop switch. The
Toggle switch is used to toggle between the
Primary and the Secondary in redundancy
mode.
The appropriate power supply and the 9-pin
Sub-D connector for the diagnostic interface
(see Sections 4.1.5 and 5.4) are located in
the lower part of the front panel.
