Model 1600 & 2600

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.

The Control will open the capacitor bank when the user selected OPEN TIME occurs. Both

settings are subject to the weekend settings.

OLTAGE - The Control will close the capacitor bank when the sensed line voltage drops

below the user selected CLOSE VOLTS setting. The Control will open the capacitor bank

when the sensed line voltage rises above the user selected OPEN VOLTS setting.

TIME WITH OLTAGE O ERRIDE - The Control will function according to the time mode,

except the time mode operating conditions will be overridden by voltage conditions

according to the volt mode function.

TEMPERATURE - For Summer Schedule (defined by CLOSE TEMP greater than OPEN TEMP

setting) - the Control will close the capacitor bank when the sensed ambient temperature

rises above the user selected CLOSE TEMP setting. The Control will open the capacitor bank

when the sensed ambient temperature drops below the user selected OPEN TEMP setting.

For Winter Schedule (defined by OPEN TEMP greater than CLOSE TEMP setting) - the Control

will close the capacitor bank when the sensed ambient temperature drops below the user

selected CLOSE TEMP setting. The Control will open the capacitor bank when the sensed

ambient temperature rises above the user selected OPEN TEMP setting.

TIME WITH TEMPERATURE O ERRIDE - The Control will function according to the time

mode, except the time mode operating conditions will be overridden by temperature

conditions according to the temp mode function.

TEMPERATURE WITH OLTAGE O ERRIDE - The Control will function according to the

temp mode, except the temp mode operating conditions will be overridden by voltage

conditions according to the volt mode function.

TIME WITH OLTAGE AND TEMPERATURE O ERRIDE - The Control will function according

to the time mode, except the time mode operating conditions will be overridden by

temperature conditions according to the temp mode function and/or by voltage conditions

according to the volt mode function. Voltage will override both time and temperature.

AMPS - The control will close the capacitor bank when the line amps drop below the user

selected Amps setting. The control will open the capacitor bank when the line amps rise

above the user selected Amps setting.

AMPS WITH OLTAGE O ERRIDE - The Control will function according to the Amps

settings, except the Amps setting operating conditions will be overridden by voltage

conditions according to the volt mode function.

K AR - The Control will close the capacitor bank when the line KVAR rises above the user

selected KVAR setting. The Control will open the capacitor bank when the line KVAR drops

below the user selected KVAR setting.

K AR WITH OLTAGE O ERRIDE - The Control will function according to the KVAR

settings, except the KVAR setting operating conditions will be overridden by voltage

conditions according to the volt mode function.

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.

Failure to comply can result in death, personal injury or equipment damage.

INSTALLING INTO A RINGED BASE

Align the terminals on the back of the Control and press firmly into the meter socket.

Use the supplied ring to complete the installation. Attach a ground wire to the external

ground lug. Seal or lock the ring only after the entire system has been verified.

INSTALLING POLE MOUNTED CONTROLS

Pole Mounted Controls are mounted with the included pole bracket and user supplied

mounting straps or lag screws. After the Control is attached to the pole, attach a ground

wire to the external ground lug.

WIRING INSTALLATION:

Use the following wiring diagram

for installing a VarCom control:

Note that the line current sensor connections

are polarity sensitive. A control indication of

reverse power flow can often be corrected by

reversing the black and white leads from the

line current sensor from those shown

in this diagram.

CURRENT SENSOR

The VarCom 2600 Control is supplied ready

to operate with Lindsey™ CVMI or Fisher

Pierce™ 1301 overhead current sensors,

which can be purchased separately. The

sensor output must be 600A: 10V. If the

current sensor is connected to a phase

different than the Control supply voltage,

refer to the software section of this

manual (beginning on pg 18)

to make phase adjustments.

Voltage sensing for the Control is pre-wired

to use the supply voltage, typically 120 or 240V.

Please consult the factory for other configurations.

FUSIN

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.

MANUAL OPERATION

All VarCom Controls can be used to operate

the connected capacitor bank switches

manually. To manually CLOSE or OPEN

the capacitor bank using the Control

front panel rocker switch:

1) Switch the Control out of the AUTO

mode, verify that the red lamp is off,

and select TIME DELAY. Using the

ADJUST knob, select the desired time

delay, in seconds, from 3 to 600. This

will delay both manual and automatic

operations by the time selected. The

OPERATION PENDIN light flashes

before every open or close operation

during the time delay period.

2) Use the MANUAL rocker switch to OPEN

or CLOSE the capacitor bank switches.

The OPERATION PENDIN light will flash

for the duration of the selected TIME

DELAY. When the output is energized, the

CLOSE or OPEN light will flash. Then, the

output will de-energize and the

light will remain on.

The capacit r bank cann t perf rm a

cl se perati n less than 5 minutes after

a trip perati n t all w time f r the

capacit rs t discharge. If a CLOSE

perati n is attempted during this

5 minute time peri d, the C ntr l will

display 5MIN DLY and the C ntr l

will n t cl se the bank.

Series 1600 Controls

Series 2600 Controls

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. Similarly, pending automatic operations can be canceled by switching out

of AUTO to any other switch position.

PRO RAMMIN FOR

AUTOMATIC OPERATION

Programming and set-up information

for VarCom Controls.

Settings Common to all Models

AUTO is the normal automatic operating

mode for the Control. The display shows

the operations counter, which cannot

be reset. The operations counter counts

all CLOSE operations.

TIME DELAY sets the time delay, in seconds,

for both manual and automatic operations.

The delay can be set from 3 to 600 seconds

in 3 second increments using the ADJUST

switch. The OPERATION PENDIN light

flashes before every open or close operation

during the entire time delay period.

MAX OP’S/DAY sets the maximum number of

automatic capacitor bank CLOSE operations

per rolling 24-hour period. This can be set

from 2 to 24 operations using the ADJUST

switch. This setting overrides all other time,

temperature, current or voltage settings. If the

daily operations limit is reached, the display

will alternately show the operations counter

and OP LIMIT while the Control is in AUTO

mode. When MAX OPS is reached, the last

operation will be an OPEN. Manual

operations do not count against the

limit set by MAX OPS/DAY.

KVAR KVAR

KVAR with voltage override KVAR/VOLT

SCHEDULE SETTIN S

Four independent time schedules are available - SCHEDULE 1 through SCHEDULE 4.

Each time schedule allows one OPEN and one CLOSE operation per day. The schedules

can be used to set multiple OPEN and CLOSE operations for each day or they can be

used for seasonal changes to the schedule, e.g. different OPEN and CLOSE times for

summer and winter.

For each schedule selected, week days MON-FRI, weekend days SAT and SUN, and

HOLIDAYS can be selected to be ACTIVE or OFF. ACTIVE days will follow the TIME ON

and TIME OFF settings as well as any temperature or voltage override settings. OFF

days will cause the capacitor bank to remain open.

The six standard holidays are New Years Day, Memorial Day, July 4th, Labor Day,

Thanksgiving Day and Christmas Day. The VarCom Controls allow a maximum of ten

holidays to be programmed.

Series 2600 Controls

EXAMPLE 1 - SEASONAL ARIATION - 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). TIME SCHEDULE 2 is a

winter schedule with a START DATE of 10/1, a STOP DATE of 3/31, TIME ON at 08:00 and

TIME OFF at 16:00. For each time schedule, the days of the week, TIME ON, TIME OFF

and override settings (if any) can be set independently.

In this example, each schedule is ACTIVE for all days of the week and holidays and sched-

ules 3 and 4 are not used. The CONTROL MODE is set for TIME, so voltage and temperature

settings are not used.

To disable a time schedule, set the start date the same as the stop date. To make a

schedule run year round, set the start date for 01/01 and the stop date for 12/31. In

case of a conflict between time schedules, SCHEDULE 1 takes priority over SCHEDULE

2, SCHEDULE 2 over SCHEDULE 3, etc. In case of a conflict between temperature and

voltage settings, voltage takes priority. To make a time schedule active for 24 hours,

set TIME ON the same as TIME OFF.

EXAMPLE 2 - TIME WITH OLTAGE O ERRIDE - Two time schedules are used for

year-round time and voltage control. SCHEDULE 1 is a weekday schedule for time with

voltage override. Set the CONTROL MODE for VOLT/TIME (time with voltage override).

The TIME ON is 08:00 and the TIME OFF is 18:00. Set MON-FRI to ACTIVE and set SAT,

SUN and HOLIDAYS to OFF. The START DATE is 1/1 and the STOP DATE is 12/31.

The Control will anticipate voltage changes caused by opening and closing the capacitor

bank. This may cause scheduled open or close operations to be deferred or delayed.

See the Voltage Settings section (pg 10) for more information about Adaptive Trip.

Example 2

Example 1

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. If the Control does not close the bank at the TIME ON

setting or open the bank at the TIME OFF setting due to voltage conditions, it will open or

close the bank later if the line voltage changes. The Control will also close the bank before

the scheduled time of 08:00 if the line voltage drops below the CLOSE VOLTS setting.

SCHEDULE 2 is a weekend schedule for voltage control only. Set the CONTROL MODE for

VOLT (voltage control). For 24-hour control, set the TIME ON and TIME OFF to the same

time. Set MON-FRI to OFF and SAT, SUN and HOLIDAYS to ACTIVE. Set the START DATE to

1/1 and the STOP DATE to 12/31. The Control will change from a weekday to a weekend

schedule at midnight.

If 24-hour voltage control is not desired, the TIME ON and TIME OFF settings can be set

as needed. The Control will close the bank at TIME ON only if the line voltage is below the

OPEN VOLTS setting less the Adaptive Trip bias voltage. The Control will open the bank at

TIME OFF independent of voltage.

EXAMPLE 3 - TIME WITH TEMPERATURE AND OLTAGE O ERRIDE - Two time

schedules are used for seasonal variations in temperature and voltage override settings.

SCHEDULE 1 is set for TEMP/TIME (time with temperature override) using the CONTROL

MODE setting. This is a daily summer schedule so the START DATE is 4/1 and the STOP

DATE is 9/30. The TIME ON is 08:00 and the TIME OFF is 18:00. The OPEN TEMP is 60°F

and the CLOSE TEMP is 80°F. MON-FRI SAT, SUN and HOLIDAYS are all set to ACTIVE.

IMPORTANT! Time with temperature override means that temperature takes precedence.

For these SCHEDULE 1 settings, the Control will close the bank at 08:00 only if the

temperature is above the OPEN TEMP setting of 60°F. Conversely, the Control will

open the bank at 18:00 only if the temperature is below the CLOSE TEMP setting of

80°F. If the Control does not close the bank at the TIME ON setting or open the bank

at the TIME OFF setting due to temperature conditions, it will open or close the bank

when the temperature changes. The Control will also close the bank before the

scheduled time of 08:00 if the temperature increases above the CLOSE TEMP setting.

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.

OTHER SETTIN S

Besides the four independent time schedules, there are three other time settings

to be entered. DAYLIGHT SAVINGS can be set to ACTIVE or OFF. Selecting ACTIVE

automatically adjusts the internal clock and all time settings for daylight savings

time in the spring and fall. Selecting OFF causes the Control to ignore daylight

savings time changes.

SET TIME and SET DATE are used only for initial set-up of the Control, or after

the back up duration has been exceeded. The time is entered in 24 hr. format

and manually adjusted in 5-minute increments. The date is entered as mm-dd-yy.

[The first day in the year 2000 will be displayed as 1/1/00]. Reference the VarWare

software for setting the date and time.

Voltage Settings

OPEN VOLTS must be at least 3 volts above CLOSE VOLTS and cannot be set to any

voltage difference less than 3 volts. The control voltage is measured and averaged

over a 5-minute period to reject momentary spikes or sags. The Control will not

respond to short-term voltage changes such as those caused by a sudden line

voltage change or adjusting the control voltage with a variable transformer.

Voltage Controls also incorporate Adaptive Trip; the Controls are sensitive to the

voltage rise caused by closing the capacitor bank. The voltage rise caused by closing

the capacitor bank is averaged over the last 4 close operations and is used to anticipate

the voltage change for the next close or open operation. This voltage change is used

as a bias, and if the next close operation would cause the Control voltage to be above

the open voltage set-point, the close operation is not performed until the voltage

falls below the open voltage set point less the bias voltage. Similarly, if the next open

operation would cause the Control voltage to be below the close voltage set point,

the operation is not performed until the voltage rises above the close voltage set

point plus the bias voltage. The initial factory default bias setting is 2 volts.

Temperature Settings

OPEN TEMP cannot be set closer than 5°F above or below CLOSE TEMP. OPEN TEMP

can be either higher or lower than CLOSE TEMP for summer or winter peaking loads.

Temperature is measured and averaged over a 30 minute period so the Control will

better respond to temperature sensitive VAR loading. The Control will not respond

to short-term temperature changes such as those caused by spraying cold water on

the temperature sensor.
