Communications Protocol
If the switch control is connected to a SCADA communication system, this is the commu-
nications protocol that is loaded in the control. If no communications protocol is present,
this field displays a
None message.
Application
If the switch control is programmed for any active control functions or application-specific
features, such as event-driven data logging or custom features, these features are listed
in this field.
Sensor Conditioning Module
This is the version of the S&C Sensor Conditioning module presently installed in the switch
control. This information helps S&C staff troubleshoot switch control problems.
Operation Counter (If applicable)
This is the number of completed close operations performed on the line switch. The switch
control only counts operations that begin with a SCADA or faceplate close command,
while the switch is in a valid open position, and end with a closed signal from the switch’s
status circuits. The switch control filters out excess control signals or intermittent digital
input state changes.
Control Power-Fail History: …Off: …On:
This is a chronological listing of switch control power loss, when both ac and battery
power are lost. The log can hold information about 9 power losses, and 9 power returns.
Once the log is full, each new event over-writes the oldest event in the log. To find the
most recent power-on or power-off event, look for the message with a timestamp that is
older than the time for the message above it.
The TROUBLESHOOTING: Switch Operations screen (Figure 8) shows a chronological
listing of switch actions. Each time the line switch opens or closes, a message is entered
in this log.
To display the TROUBLESHOOTING: Switch Operations screen:
