    • Downloading new control software into the IntelliCap control • Troubleshooting installation problems The IntelliCap control reports voltage, current, and phase-related data in units of volts, amps, kvars, kW, and kVA. The rated accuracy of these measurements (±0.3% of full scale) is based on the combined accuracy of all control components, exclusive of the sensor and sensor cable, but including all sensor conditioning components.

    The control automatically switches the bank using a variety of control strategies: Temperature, Timeclock, Voltage Only, Time-Biased Voltage, Time-Biased Temperature, Automatic Online, or Automatic Offline. The IntelliCap with Var control has two additional control strategies: Current and Var. The control switches the bank based on a prioritized set of conditions. From highest to lowest priority, these are: Five-minute reclose delay—After opening the bank, the control will not close it for...
  • Page 10 IntelliCap Control Operation Timeclock Control Mode When Automatic mode is enabled and the control is configured for Timeclock mode, the control switches the bank based on a time schedule. Two different time schedules can be configured, and the control uses the following logic to determine when to switch the bank: (a) The control checks to see whether the present time is in one of the scheduled On periods.
  • Page 11 IntelliCap Control Operation (c) If voltage remains continuously above the High-Voltage Override setpoint for the duration of the Over-Voltage Override-Time timer, the control switches the bank out. If voltage remains continuously below the Low-Voltage Override setpoint for the duration of the Under-Voltage Override-Time timer, the control switches the bank in.

    High-Low button on the Data Logging Menu screen. See Figure 6. Screens can be selected to show historical information for each day of the last month. Figure 7 shows the menu for the IntelliCap with Var control. The menu for the standard IntelliCap control only contains data for the options it supports.

  • Page 16: Sensor Profiles

    Viewing Data Logging Daily High and Low Data The Daily High and Low screens show the highest and lowest values for voltage, temperature, current, power factor, kvar, or kW for a 24-hour period (12 midnight to 12 midnight). The high/low data for today and for each of the preceding 31 days is available. To display a Daily High and Low screen, click on the Data Logging button.
  • Page 17 If the correct location for the present sample is after the end of the log, the process is the same as for a new data logging interval. When an IntelliCap control is returned from the field, generate all necessary reports as soon as possible. This minimizes the amount of lost data.

  • Page 18: Switching Level Data

    Estimated Value setpoint on the Setup>General screen. When the Bank Voltage Change + Margin: Automatic Calculation mode is enabled, the control uses the delta values shown on this screen in the calculation. See Setup Instructions 1022-530, “S&C IntelliCap ® Automatic Capacitor Control: Setup” for more details.

  • Page 19: Event Logs

    Viewing Data Logging View the kvar Levels During Switching For the IntelliCap with Var control, every time the bank switches in or out (manually or automatically), the control records the kvar levels before and after switching. These values are shown on the Data Logging: kvar Levels During Switching screen.

  • Page 20: Data Graphing

    Viewing Data Logging Date and Time This is the date and time when the switching operation occurred. Request Type This is the type of request (manual, voltage override, etc.) that caused the bank to switch. View the Power Outages Log The Data Logging: Power Outages screen shows the date and time of the last 15 power cycles.
  • Page 21 Viewing Data Logging The amount of data in the sensor profile graphs depends on the configured data logging interval. See the “View the Sensor Profile Screens” section on page 16 for more details. Follow these steps to display sensor profiles: Click on the Data Graphing button.

  • Page 22: Generating Reports

    Generating Reports The IntelliCap control report feature will transfer most of the control settings and stored data to a PC as a CSV (comma-separated value) file. The report can be stored as a permanent record and used in spreadsheets or other program types. Follow these steps to generate a report: Connect a PC to the IntelliCap control and start the IntelliLink software.

  • Page 23: Saving And Logging A Setup Configuration

    Saving and Loading a Setup Configuration When several IntelliCap controls use a similar setup configuration, the configuration from one control can be saved and loaded into other controls. Only the setpoints that are different for each control need to be configured.
