Control Software
S&C control operation is software-driven. IntelliCap controls include factory-installed
control software. IntelliLink Setup Software must be installed on the computer used with
the control.
The control software manages minute-by-minute functioning of the IntelliCap control.
It continually monitors:
• Voltage on the feeder
• The position of faceplate switches
• Ambient air temperature at the control
• The control clock and calendar
• Software setpoint values
• Various other setpoints and data values
Based on this information, the control software decides how to respond to a change in
voltage, a faceplate command, and other conditions. The control software, setpoint values,
and historical data are stored in non-volatile memory that will survive a power interruption.
