The SCADA 3000 includes circuitry to monitor numerous internal system parameters to
make sure that the unit is functioning properly. Some circuits are tested on power-up while
others are monitored on a continuous basis. Whenever a monitored function goes beyond its
specified limits the Fault light is lit and a description of the problem is logged in the SCADA
3000’s Event Logger. Faults can also be viewed on the LCD display. On the Keypad, select
MENU>DATA POINTS>DIAGNOSTICS>SYSTEM FAULTS. Realtime diagnostic informa-
tion can be viewed by selecting Diagnostics from the main menu and then clicking on Processors
or Motherboard. These will display system parameters monitored within the SCADA 3000 Main
Unit. The two screens shown below:

In the event of abnormal behavior, several RESET options can be performed on the unit's
microprocessors. Within the Control processor group box is a Reset button which will issue a
hardware reset to the control processor when clicked. This reset will not destroy program-
ming. At the bottom of the Processor’s Diagnostic screen are two additional reset options.
The button labeled Hardware Reset will reset both the Communications and Control proces-
sor. This type of reset will not destroy programming; however, it will drop your connection if
done while online using the modem. The Full Factory Reset will destroy all programming and
restore the unit to factory default settings (new out-of-box). Do not click this button unless you
are absolutely sure you have all programming backed up, including: SCADA 3000 unit program-
ming, Ladder program, C-Program, DataLogger downloaded, and the Event log downloaded.
