    VarCom Capacitor Controls set the standard for ease of use by providing sophisticated control and monitoring capabilities in an intuitive easy to use package. VarWare Windows™ compatible software extends these capabilities. Please visit our website for the latest information on these and other quality HD Electric Company products. www.HDElectricCompany.com...

  • Page 3: Overview

    OVERVIEW The VarCom 1600 and 2600 Capacitor Controls utilize user selectable functions and parameters to control switched capacitor banks. The VarCom 1600 controls with time, temperature and voltage and the VarCom 2600 add Amps and KVAR control. TIME - The Control will close the capacitor bank when the user selected CLOSE TIME occurs.

  • Page 4: Installation

    INSTALLATION All VarCom Controls are supplied ready for 4 or 6 jaw meter socket mounting or for mounting directly to a pole with a supplied mounting bracket. WARNING: Before plugging the Control into a live meter socket, rotate the main switch out of the AUTO position or remove the front panel fuse, and observe all safety procedures for working with exposed live circuits.

  • Page 5: Fusing

    FUSING All VarCom Controls are supplied with a 15 Amp SLO-BLO® fuse, accessible from the front panel. This fuse protects the capacitor bank switches. If it was removed before installation, the fuse should be reinstalled after installation is complete. An internal fuse that is not field replaceable protects the Control circuitry. All repairs should be referred to the factory.

  • Page 6: Programming For Automatic Operation

    NOTE: Manual operations are counted by the operations counter (close operations only), but manual operations do not count against the preset daily limit set by MAX OPS/DAY. After completing the required manual operations, return the Control to AUTO for automatic operation. The AUTO light confirms Automatic operation. NOTE: Pending manual operations can be canceled by turning the Control to AUTO.

  • Page 7: Setting The Control Mode

    SETTING THE CONTROL MODE The Model 1600 Control can allow voltage and/or temperature to override time settings. The Model 2600 Control can allow voltage to override temperature, time, amp and KVAR settings. Depending on the model, the following Control Modes can be used: Control Display Series 2600 Controls...
  • Page 8 EXAMPLE 1 SEASONAL VARIATION - Two time schedules are used for seasonal variation in the OPEN and CLOSE times and/or override settings (if any). TIME SCHEDULE 1 is a summer schedule with a START DATE of 4/1, a STOP DATE of 9/30, TIME ON at 07:00 and TIME OFF at 18:00 (all time settings are in 24 hour format).
  • Page 9 IMPORTANT! Time with voltage override means that voltage takes precedence. For these SCHEDULE 1 settings, the Control will close the bank at 08:00 only if the line voltage is below the OPEN VOLTS setting less the Adaptive Trip bias voltage. Conversely, the Control will open the bank at 18:00 only if the line voltage is above the CLOSE VOLTS setting plus the Adaptive Trip bias voltage.

  • Page 10: Other Settings

    SCHEDULE 2 is set for VOLT/TIME using the CONTROL MODE setting. This is the winter schedule so the START DATE is 10/l and the STOP DATE is 3/31. The TIME ON is 08:00 and the TIME OFF is 18:00 MON-FRI, SAT, SUN and HOLIDAYS are all set to ACTIVE. Voltage settings are set as needed.

  • Page 11: Kvar Settings

    KVAR SETTINGS KVAR OPEN and KVAR CLOSE determine when the capacitor bank will open and close. The Control will display LD for leading KVAR and LG for lagging KVAR. KVAR CLOSE can only be set lagging and must be at least 20KVAR more than KVAR OPEN. KVAR is measured and averaged over a five minute period to reject momentary transients.

  • Page 12: System Monitoring

    SYSTEM MONITORING Depending on the model, the actual line voltage, ambient temperature or current can be monitored using the MONITOR settings. This can be helpful for setting up and checking Control operation. All parameters are measured and displayed real-time without any time delay or averaging. LINE AMPS is the total current on the line, both real and reactive.

  • Page 13: Neutral Current Monitoring

    NEUTRAL CURRENT MONITORING On units equipped with optional Neutral Current monitoring, the capacitor bank neutral line is monitored. A neutral current sensor is mounted around the capacitor bank neutral lead and is connected to the Control. High neutral current is indicative of unbalanced VAR loading and can be used to trip the capacitor bank off line and keep it off line until the Control is manually reset.

  • Page 14: Led Indicators

    The following information regarding the front panel displays may prove helpful in diagnosing a Control that appears to be functioning improperly. LED INDICATORS AUTO - Indicates the Control is in automatic mode. The Control will open and close the bank only per the programmed settings and the toggle switch is disabled. The display indicates the total number of CLOSE operations.

  • Page 15: Lcd Display

    LCD DISPLAY COMBUSY - The Control is communicating via the communications port. LOW LINE - The supply voltage has dropped below its operating threshold (92V for a 120V unit and 180V for a 240V unit). The Control will go into a standby mode until the voltage recovers and will then perform a power up self-check.

    VarWare PROGRAMMING AND DATA ANALYSIS SOFTWARE Features VarWare® software aids in programming a VarCom Capacitor Control for capacitor bank switching and power system monitoring via a computer. The software includes the following features: • Design capacitor bank control strategies in the office for future uploading to the Control. •...

  • Page 19: Software Installation

    Select File, then Open. If this is the first time for setting up a program, select one of the default programs for the Control model that is to be programmed. For example, select 1600.ws for a VarCom 1600 Control. A previously created file may also be selected. All setup files will have a .ws extension.

  • Page 20: Upload A Setup Program To A Varcom Control

    To print the Active setup file, select File, then Print. To print another setup file, select File, then Open, then Print. Upload a Setup Program to a VarCom Control To upload a setup program to a VarCom Control, follow the precautions shown at the beginning of the software section of this manual (page 18) and connect a computer to the Control.

  • Page 21: View And Graph Downloaded Profile Data

    When all desired options have been selected, select OK to update the Control. Updating Profile options erases any previously stored data in the Control. To download stored data, select Communications, then Profile, then Download profile data. The default file name is the Control ID# selected earlier (a .pro filename extension will be automatically added.) A different filename can also be entered at this time.
