Quality Standards
ISO 9001-Certified Quality Management System
Acceptance and Initial Inspection
Each Form 6 recloser control is completely assembled, tested, and inspected at the factory. It is carefully calibrated, adjusted and in good condition when accepted by the carrier for shipment.
Upon receipt, inspect the carton for signs of damage. Unpack the control and inspect it thoroughly for damage incurred during shipment. If damage is discovered, file a claim with the carrier immediately.
Handling and Storage
Be careful during handling and storage of the control to minimize the possibility of damage. If the control is to be stored for any length of time prior to installation, provide a clean, dry storage area. If storage is in a humid atmosphere, make provisions to keep the control circuitry energized.
Note: To energize the control, apply AC power to the AC supply
input terminal block located in the lower right hand corner of the back panel of the control. Refer to the Customer Connections for AC Power section in this manual.
Control Battery Storage and Charging
The 24 VDC control battery in the Form 6 recloser control is
fully charged prior to shipment and is ready for use.
IMPORTANT: To maintain sufficient charge to operate the control and prevent battery cell damage, the sealed lead-acid batteries should be charged after no more than three months of storage.
Temperature has an effect on battery life. Sealed lead acid batteries should be stored, fully charged, at room temperature. Never store lead acid batteries at temperatures
exceeding 47°C (117°F), as damage can result in
approximately one month.
The batteries must be tested and charged for 24 hours
following every three months of storage from the last test date. A separate portable charger accessory is available.
Catalog Number KA43ME7001 provides a 120 Volt battery
charger to power individual batteries.
IMPORTANT: Connect the control battery before AC power is connected to the control’s AC supply Input Terminal Block. The battery must be disconnected prior to shipping or storing the control.
Note: When shipped from the factory, the battery source is
disconnected and its output plugs are taped to the cabinet. Connect the battery plugs into the mating connectors to complete the battery circuit.
Control Power
CAUTION: Equipment misoperation. Verify that
the 120/240 VAC selector switch is correctly set
for incoming voltage. Failure to comply may cause
misoperation (unintentional operation) of the control and/
or equipment damage resulting in personal injury. T278.0
CAUTION: Equipment damage Form 6-LS (Loop Scheme). Do not connect 240 VAC to B or Y phases on terminal blocks TB7 or TB8. 240 Volts will damage
internal components and cause control misoperation. T314.0
The Form 6-LS control is powered from 120 VAC. The selector switch on the power supply board must be set to the 115V position.
Battery Replacement and Disposal
The 24 VDC control battery has a life expectancy of four
years. It is recommended that the battery be replaced after four years or if the battery fails a battery test - whichever occurs first.
Note: Battery life is decreased at higher temperatures.
Dispose expired batteries in an environmentally responsible manner. Consult local regulations for proper battery disposal.

Form 6-LS Pole Mount Recloser Control Installation and Operation Instructions
Operation Upon Loss of AC Power
The control is equipped with a 13 Amp-Hour 24 VDC lead
acid battery for operation upon loss of AC power. The control maintains full operation from the battery for a period
of time — 24 hour maximum (20°C)
In the event that the AC power has not returned within the times listed above, the control will disconnect the battery from the circuit.
Note: The control continuously monitors the battery voltage. To
prevent battery damage, the control shuts down automatically upon detection of low battery voltage
(below 22 VDC) for 60 seconds.
Control programming settings and parameters—including event recorder—are stored in non-volatile memory and retained upon loss of control power. The time/date clock will continue to operate for approximately 30 days after loss of control power.
Phase B and Y inputs are the factory default connections for powering the control. If B and Y phases lose AC power,
the red ALARM indicator LED will illuminate, the green CONTROL OK indicator LED will not be illuminated, and the ALARM log on the LCD display will indicate NO AC PRESENT.
IMPORTANT: If the the control shuts down due to low battery voltage before AC power is restored, and the connected energized recloser is CLOSED; it will only TRIP and LOCKOUT via front panel pushbutton command.
A control that has shut down due to low battery voltage before AC power is restored will have a blank LCD
display (no text message shown) and none of the LEDs
will be illuminated.
The control clock may require resetting if the operating power has been disconnected for more than thirty days. Refer to ServiceInformationS280-70-4(ProView4.X.X)or
S280-70-21 (ProView 5.X.X) Form 6 Microprocessor­BasedRecloserControlProgrammingGuide for information
on setting the control clock.
Note: When AC power is present, the control will operate
regardless of back-up battery presence.
Note: In the event of loss of AC control power to the control
(without battery back-up power), the LS control will be
disabled when power is restored to the control:
• In the TIE Mode, once voltage is restored, the LS is
disabled until locally or remotely enabled. This is to ensure that the TIE recloser will not close automatically upon restoration of voltage from one source.
• In the SECTIONALIZING mode, once voltage is
restored, the LS is disabled until locally or remotely enabled. The recloser remains in the same state prior
to the loss of voltage. The SECTIONALIZING unit will
not close automatically. This also prevents any automatic closing when auto reset is enabled.
Note: LS must be enabled via the ProView interface software
Loop Scheme Settings Dialog screen located in the Idea Workbench.
FORM 6-LS RECLOSER
CONTROL DESCRIPTION
Description
The Form 6-LS pole-mount microprocessor-based recloser control includes extensive auto-reconfiguration system protection functionality, including phase, ground, and negative sequence overcurrent protection, over/ underfrequency, and voltage protection, directionality, sensitive ground fault, and sync check.
The control is for application in distribution feeder loop sectionalizing schemes. The Form 6-LS control senses the loss of voltage, and after a predetermined time delay, performs the programmed action to restore service to the affected feeder.
The control can be programmed for either the sectionalizing or tie mode of operation. The sectionalizing mode senses voltage on the source side of a normally closed recloser and is activated upon loss of source-side voltage. The tie mode of operation senses voltage on both sides of a normally open recloser and is activated upon loss of voltage on either side. The tie mode is used for both one­way and two-way tie applications.
Analysis tools include fault locating, event recording, TCC Editor II, Idea Workbench, Data Profiler, and oscillography functions, including oscillography replay.
Metering functions include demand and instantaneous current on a per-phase basis, instantaneous voltage and
power factor on a per-phase basis, and power (real, reactive, apparent) on a per phase or total basis.
Symmetrical components for both voltage and current are displayed along with kilowatt-hours for energy metering. Harmonics from the 2nd to the 15th harmonic are also included.
The front panel LCD display is used to configure the operating settings for the control. It is also used to display metering, counter information, control parameters, reset alarms, and provide diagnostic information.
Control parameters can also be programmed via a personal computer connected to the control through the front panel RS-232 port. Control programming, interrogation, and operations are performed with Form 6 ProView interface software on a personal computer.
ProView interface program software includes additional functions used to create and graphically display Time Current Curves and provides the Idea Workbench for configuring user-selected inputs and outputs, configurable event and alarm data, and selectable communication points for serial communication.
The control operates on 50 and 60 Hz systems.
The control can be configured, by the factory or by the user, for a wide variety of applications. If user requirements change, the control functions can be modified to meet the new requirements.
The control is accessible from both the front and back of
the cabinet (Figure 2).

Theory of Operation
A functional block diagram of the Form 6-LS recloser con­trol is shown in Figure 3. Current sensing is provided by three current transformers located in the recloser and inter­faced to the Form 6 recloser control via the control cable. This cable also supplies Trip, Close, and Recloser status,
and connects to the Recloser Interface (RIF) module to
provide isolation for reliable operation. Voltages for meter­ing are connected to the analog input module through terminal block TB8.
Line current flowing through the recloser is converted by the CPU module to a digital signal suitable for metering and fault current calculations. Data sampling occurs at a rate of
64 times per cycle. The CPU contains a data acquisition
section that uses the acquired samples to compute the fundamental currents and voltage for use in overcurrent, under/overvoltage, and under/overfrequency protection, as well as currents and voltages for metering functions.
S280-70-10
The current for overcurrent protection is calculated on a sub-cycle basis; it includes only the fundamental and DC component.
When the phase or ground current exceeds its pro­grammed minimum-trip value and associated time-cur­rent-curve (TCC) timing, the control initiates the pro­grammed sequence of recloser tripping and reclosing operations via the CPU and RIF modules. If the fault is temporary, the control ceases to command recloser oper­ations after a successful reclose, and the control resets to the start of its operating sequence after a preset time delay. If the fault is permanent, the control performs its complete programmed sequence of reclose commands and locks out with the recloser open. Once locked out, the control must be closed via the operator panel or SCADA communications. This resets the control to the start of the operating sequence.
The following chain of events occurs for an operating
sequence of two trips to lockout (one trip on TCC1, one trip on TCC2):
1. The overcurrent signal is integrated with time on the selected curve for the first trip operation (TCC1) to pro­duce the signal which energizes the trip circuit.
2. Energizing the trip circuit connects the supply to the trip solenoid to open the recloser.
3. Upon opening, the control starts timing on the first reclosing interval-delay time.
4. Upon expiration of this reclosing interval-delay, a clos­ing signal is issued from the control, closing the reclos­er, and selecting the time-current characteristics for the
second trip operation (TCC2).
5. If current remains above the minimum-trip level, the recloser will trip on TCC2 and lockout the recloser.

All of the default status indicators LEDs (except for CONTROL OK, CONTROL POWER, and ALARM) can be
reconfigured via the Idea Workbench. Refer to Service Information S280-70-4 (ProView 4.X.X) or S280-70-21 (ProView 5.X.X) Form 6 Control Programming Guide for
additional information.
The label inserts can be user-customized. Refer to Using Removable Inserts section of this manual for additional information.
CONTROL OK: The green LED indicates the control is operating normally and not in an alarm state.
The CONTROL OK LED will not be illuminated during these
alarms (indicated by the red ALARM LED and displayed in the alarm status log):
• Battery Alarm: This alarm indicates battery voltage is
low or the battery failed an operator-initiated manual test.
• RAM Failure: This alarm indicates a failed RAM memo­ry test.
• ROM Failure: This alarm indicates a failed ROM mem­ory test.
• No AC Present: This alarm indicates AC power was
unavailable for 10 continuous seconds. This alarm resets when AC power is restored.
• Power Supply Malf[unction]: This alarm indicates
internal control operation power was outside of its operating tolerance for more than 20 seconds. This alarm resets when the internal control operation power returns to operation within its normal tolerances.
• RIF Comm Failure: This alarm indicates a loss of communication from the RIF (Recloser Interface) circuit
board to the main CPU circuit board. This alarm resets if communication is re-established.
CONTROL POWER: The green LED indicates there is adequate VTC voltage to trip the recloser. This LED does not indicate the presence of AC or battery power.
CONTROL LOCKOUT: The green LED indicates the control is in a locked out state, i.e. a reclosing sequence is not in progress. This LED does not indicate that the recloser is open.
RECLOSER OPEN: The green LED indicates the recloser is in the open position.
RECLOSER CLOSED: The red LED indicates the recloser is in the closed position.
Note: There are several conditions that will cause the alternate
blinking of the CONTROL LOCKOUT, RECLOSER OPEN, and RECLOSER CLOSED LEDs: Failure to Trip, Failure to Close, Interrupter Malfunction, and 52a/b Disagreement.
The LED blinking pattern for these conditions is the
CONTROL LOCKOUT green LED and RECLOSER CLOSED red LED alternating with the RECLOSER OPEN green LED.
In addition to the above LED blinking pattern, the red
ALARM LED will also be illuminated for these alarms: Failure to Trip, Failure to Close, and Interrupter Malfunction.
A PHASE FAULT, B PHASE FAULT, C PHASE FAULT: The red LEDs indicate A, B, and/or C phase current was either the maximum phase current or within 20% of the maximum when a trip signal was issued.
GROUND FAULT, SENSITIVE GROUND FAULT: The red LEDs indicate that a Ground and/or Sensitive Earth Fault tripping function was asserted at the time the trip signal was asserted.
ALARM: The red LED indicates an alarm has been issued. Review the alarm status and log on the LCD display for the specific alarm.
ABOVE MINIMUM TRIP: The red LED indicates the current exceeds the level set for minimum trip.

S280-70-10
TIE: The red LED indicates the control is in tie mode and will respond to voltage conditions on Source I and/or Source II.
SECTIONALIZER: The red LED indicates the control is in
sectionalizing mode and will respond to voltage conditions on Source I.
Note: When in Sectionalizing mode, the SOURCE II ENABLED
function key is not responding to voltage even though it is illuminated.
LS DISABLED: The red LED indicates the LS accessory is not active. When LS is disabled, the Form 6-LS control will not respond to the LS loss of voltage parameters as set in the ProView interface software Loop Scheme Settings Dialog screen located in the Idea Workbench.
Note: In the event of loss of AC control power to the control
(without battery back-up power), the LS control will be
disabled when power is restored to the control:
• In the TIE Mode, once voltage is restored, the LS is
disabled until locally or remotely enabled. This is to ensure that the TIE recloser will not close automati­cally upon restoration of voltage from one source.
• In the SECTIONALIZING mode, once voltage is
restored, the LS is disabled until locally or remotely enabled. The recloser remains in the same state prior
to the loss of voltage. The SECTIONALIZING unit will
not close automatically. This also prevents any auto­matic closing when auto reset is enabled.
Note: LS must be enabled via the ProView interface software
Loop Scheme Settings Dialog screen located in the Idea Workbench.
A PHASE VOLTAGE, B PHASE VOLTAGE, C PHASE VOLTAGE: These red memory LEDs indicate the appropri-
ate phase(s) that initiated the Loop Scheme functionality.
These LEDs are controlled by the Voltage Controls settings in the Loop Scheme Settings dialog box.
If LS is enabled, at the moment loss of voltage occurs, the LEDs for the phases that lost voltage turn off and the LS option begins timing.
Note: The TIE mode will not initiate any loss of voltage timing if
both sources are lost. If one source is available, while the TIE mode is timing on loss of voltage, and the available source also loses voltage, the TIE will reset the loss of voltage time to its original value.
If voltage is restored before the voltage transfer time delay elapses, the LEDs for the phases with restored voltage illuminate and the LS timer resets.
If voltage is not restored before the Voltage Transfer time delay relay elapses, the LEDs remain off even if voltage returns to a particular phase. This identifies the phase that caused the LS to operate.
Activating the LS RESET one-touch function key resets
the LS function and illuminates these LEDs (if voltage is present).
FREQUENCY TRIP: Indicates the recloser tripped due to
an under or over frequency condition.
VOLTAGE TRIP: Indicates the recloser tripped due to an under or over voltage condition.
X PHASE VOLTAGE, Y PHASE VOLTAGE, Z PHASE VOLTAGE: These red memory LEDs indicate Source II (load) voltage is present on X, Y, or Z phase(s). These LEDs are
controlled by the Voltage Controls settings in the Loop Scheme Settings dialog box.
If LS is enabled, at the moment loss of voltage occurs, the LEDs for the phases that have lost voltage turn off and the LS option begins timing.
Note: The TIE mode will not initiate any loss of voltage timing if
both sources are lost. If one source is available, while the TIE mode is timing on loss of voltage, and the available source also loses voltage, the TIE will reset the loss of voltage time to its original value.
If voltage is restored before the voltage transfer time delay elapses, the LEDs for the phases with restored voltage illuminate and the LS timer resets.
If voltage is not restored before the Voltage Transfer time delay relay elapses, the LEDs remain off even if voltage returns to a particular phase. This identifies the phase that caused the LS to operate.
Activating the LS RESET one-touch function key resets the
LS function and illuminates these LEDs (if voltage is present).
INDICATOR 7, INDICATOR 8: Customizable LEDs that are used with functions programmed through the Idea Workbench. The LED indicators do not have active default values. The LEDs are illuminated when the status config­ured via the Idea Workbench is present.

HOT LINE TAG ON/OFF Toggle Switch and LED Indicator
WARNING: Hazardous voltage. Do not use Hot
Line Tag as a substitute for a visible disconnect. Always establish a visible disconnect prior to performing any work requiring a de-energized line. Failure to comply may cause death, severe personal injury, or equipment damage. T276.0
Hot Line Tag is provided for live-line work applications. All closing operations are disabled when the Hot Line Tag feature is activated.
IMPORTANT: Hot Line Tag activation does not cause the recloser to trip open. It only prevents the recloser

from closing.
CLOSE Pushbutton
IMPORTANT: Hot Line Tag is intended solely for live-line work applications, such as maintenance, repairs or improvements to the distribution system, that occur while the line remains energized.
Hot Line Tag prevents all closing attempts from the control and shifts protection to one trip-to-lockout on the composite curve of the Hot Line Tag definite time and the TCC1 curve (whichever is faster). Hot Line Tag takes precedence over Cold Load Pickup, Non-Reclosing, and Fast Trips Disabled.
Hot Line Tag is activated from either the operator panel toggle switch, serial communications, or a discrete SCADA function. All sources must be off to de-activate Hot Line Tag.
To activate the function from the operator panel, flip toggle switch up to the ON position. See Figure 7. The LED indicator illuminates when the function is active.
The Hot Line Tag function may only be reset by the source which initiates it. For example, if Hot Line Tag is activated at the operator panel, the reset function is only possible at the operator panel, and not via SCADA command.
When pressed, the CLOSE pushbutton (Figure 7) returns
the control to the initial or home sequence position, closing the recloser. The control is ready for the start of a new trip/ close sequence.
Note: The Close Malfunction alarm must be reset before
Closing will be allowed.
Note: Pressing the CLOSE pushbutton from the Lockout
position initiates Cold Load Pickup (CLPU) protection, if
the feature is enabled.
The user does have the ability to block COLD LOAD
PICKUP through the LCD menu or by configuring one of the Option one-touch function keys via the Idea Workbench feature in ProView.
If the recloser is closed, pushing and holding the CLOSE
pushbutton does not activate the Cold Load Pickup feature. See Cold Load Pickup in the Control Features section of this manual.
IMPORTANT: If the CLOSE button is pressed after the Close Circuit Disable fuse is removed, do not reinstall the
fuse until after the ALARM LED illuminates (within approximately five seconds) to indicate CLOSE
MALFUNCTION. Re-installing the Close Circuit Disable fuse prior to the CLOSE MALFUNCTION ALARM indication will cause the control to close the recloser.
IMPORTANT: If the power save feature is enabled
(default), and more than ten minutes elapses since the
last panel operation, all the LEDs, except HOT LINE TAG
(if active), will turn off.
TRIP (Lockout) Pushbutton
The TRIP pushbutton (Figure 7) provides front-panel access to trip (lockout) the recloser. When pressed, the
TRIP pushbutton opens the recloser and locks out the control.
Note: In the event of main microprocessor failure, the trip circuit
10
can operate independent of the main microprocessor.
CLOSE CIRCUIT DISABLE
Close Circuit Disable (Figure 7) is a removable fuse that,
when removed from the front operating panel, disables the close circuit from the control to the recloser. Removing the fuse from the control disables all electrical closing of the recloser and provides a physical disconnect to the recloser closing circuit. As a result, the control cannot perform a close operation. This disconnect overrides all close functions and makes a remote or manual close operation impossible.
Note: When the Close Circuit Disable fuse is removed, the trip
circuit remains active and will trip per the programmed time current curve for a faulted condition.

Figure 8. Form 6-LS control operator panel one-touch function keys.
Red LEDs located on each function key indicate the status of the function, regardless of local or remote activation. For example, if Ground Trip Blocked is activated from a SCADA signal, the red indicator will illuminate even though it was not activated from the operator panel.
Operator panel function key activation or de-activation
requires the operator to first press the CHANGE key to enter the CHANGE mode. A function must then be selected or de-selected within ten seconds to activate or de-activate the function. Once selected, the control returns to normal operation until prompted for another change request. This prevents accidental changing of functions of features.
Note: Only one function can be changed per each CHANGE
mode activation.
GND TRIP BLOCKED
The Ground Trip Blocked function blocks all ground sens­ing in the control for the active profile. This red indicator is illuminated when Ground Trip Block is activated from the
serial port, I/O, the interface software, or locally (via the front panel) causing the control to block all ground sensing.
NON RECLOSING
The Non-reclosing mode disables any automatic reclosing operations. The red indicator is illuminated when the control is operating in a non-reclosing mode. Non-reclosing does not alter the active TCC. Activation is possible from
the SCADA port, I/O, the interface software, or locally (via the front panel).
SUPERVISORY OFF
When the SUPERVISORY OFF red indicator is illuminated,
supervisory commands are blocked. Supervisory functions through the back panel serial communication ports and the discrete I/O are blocked. Serial communications through the front panel RS-232 port remain active independent of
the status of the SUPERVISORY OFF switch. Activation of
this function key is restricted to the operator panel and is accomplished by pressing the CHANGE key and then
pressing the SUPERVISORY OFF key. Operational data
and metering information are available while the control is
in the SUPERVISORY OFF position. The TRIP and CLOSE
pushbuttons and Hot Line Tag are active independent of
the SUPERVISORY OFF function.
LS RESET: When the LS RESET red indicator is illuminated, the LS function has been reset and the control is ready to respond to the next loss of voltage occurrence. Activation
is possible from the SCADA port, I/O or locally (via the front panel). This LED cannot be de-selected. It will only turn off
when an LS action occurs.
SOURCE I ENABLED: When the SOURCE I ENABLED red indicator is illuminated, the control is in LS mode and
responding to voltage conditions on Source I (Source side Phases A, B, and C). Activation/de-activation is possible
from the SCADA port, I/O, the interface software, or locally
(via the front panel).
SOURCE II ENABLED: When the SOURCE II ENABLED red indicator is illuminated, the control is in Tie mode and
responding to voltage conditions on Source II (Load side Phases X, Y, and Z). Activation/de-activation is possible
from the SCADA port, I/O, the interface software, or locally
(via the front panel).
Note: When the control is in Sectionalizing mode, the SOURCE
II ENABLED function key may or may not be illuminated
(depending on the LS Enable SII setting in the Loop Scheme Settings Dialog box). It is not responding to
Source II voltage.
OPTION #1, OPTION #2, AND OPTION #3
The OPTION #1, OPTION #2, and OPTION #3 function keys must be programmed via the ProView Idea Workbench software.
The OPTION LEDs are illuminated when the options configured via the Idea Workbench are selected. Refer to

for additional information.
These OPTION keys provide a momentary signal. For instance, these keys can be programmed to toggle control status, protective functions, or a momentary input pulse.
The OPTION #1, OPTION #2, and OPTION #3 function keys are intentionally not defaulted to any function. The functions are assigned to each OPTION key via the Idea Workbench application.

Form 6-LS Pole Mount Recloser Control Installation and Operation Instructions
Control Features
The Form 6-LS recloser control offers numerous standard features and accessories that allow the user the utmost flexibility applying the recloser control.
Control Security
The Form 6-LS control has multiple customer-programmable security codes to limit control programming and viewing function access to authorized personnel. The front panel
Man-Machine Interface (MMI) includes a user-selected
security code to access the settings. Plus, the ProView interface software has it’s own security levels for multiple­user access.
Refer to ServiceInformationS280-70-4(ProView4.X.X)or
S280-70-21(ProView5.X.X)Form6ControlProgramming Guide for additional information.
Protection Profiles
Four protection profiles capable of fully specifying control operation are standard in the control. Each protection pro­file includes the following as a minimum:
• Overcurrent Protection
• Over/Undervoltage Protection
• Over/Underfrequency Protection
• Directional Protection
• Hot Line Tag Functionality
• Sync Check
• Sensitive Earth Fault Protection
• Sequence Coordination
• Operation Settings
Time Current Curves
Time-current curves are available for numerous functions, including fast and delayed operations for phase, ground, and negative sequence protection. Each time-current is selected from a defined fifty curves which can be further customized by the user. The time-current curves are also selected from a graphical TCC Editor II to visualize any modifications prior to configuring the control.
The time-current curves include the following modifications for phase, ground, and negative sequence protection:
• Time Multiplier with a range of 0.1 to 25 in .1 increments.
• Time Adder with a range of 0 to 30 seconds in .01
second increments.
• Minimum Response Time with a range of 0.01 to 1
seconds in .001 second increments.
• High Current Trip multiplier with a range of 1 to 32
multipliers in increments of 0.1.
• High Current Trip Time Delay with a range of 0.01 to
.150 second in .001 second increments.
• Time Dial Reset co-efficient with a range of .1 to 30
seconds in 1 second increments.
Sequence Coordination
Sequence Coordination eliminates nuisance tripping through trip coordination. It allows the control to step through selected operations in the operating sequence without tripping. The number of Sequence Coordination advances is programmable from one to three operations to provide trip coordination with a downline recloser. This feature is independently selectable for each protection profile.
Cold Load Pickup
The control includes a Cold Load Pickup feature to prevent the control from tripping while energizing non-fault system loads. This feature has independently programmable minimum trip value time-current curve, reclose interval, and number of independent operations to lockout for each protection profile. Cold Load Pickup also includes TCC Multipliers, TCC Adders, Minimum Response Time, Time Dial Reset, and High Current Lockout. Also, direct values, not multiples of minimum trip, are provided for high current lockout.
Fast Trips Disabled
The control includes a Fast Trips Disabled feature to modify protection, so that all trip operations use the programmed TCC2. This feature is independently selectable for each protection profile. All trip operations will time on TCC2. Typically, TCC1 is fast and TCC2 is delayed. So, as an example, the control will change it’s sequence from 2 fast and 2 delayed operations to 2 operations on TCC2 when Fast Trips Disabled is active.
High Current Lockout
The High Current Lockout feature will automatically lockout the control on the selected operation when current exceeds a programmable level. The active trip numbers for the lockout is selectable for phase, ground, and negative sequence. This feature is independently selectable for each protection profile.
Sensitive Ground/Earth Fault Operation
The control has a Sensitive Ground/Earth Fault Trip feature that provides tripping of the recloser after a programmable, definite time for ground currents below normal ground minimum trip levels. The feature has programmable operations to lockout and reclose intervals independent of the ground settings. This feature is independently selectable for each protection profile.
Thermostatically Controlled Heater
The control has a standard 15 Watt thermostatically
controlled heater (ON at 70°F on falling temperature, OFF at 85°F on rising temperature) for humidity control and
voltage input independent. The heater is powered from the power supply board.

S280-70-10
Metering
The control provides instantaneous and/or demand metering with programmable integration intervals for the following functions:
• Real and reactive power for each phase and total,
including directional, on an individual phase basis.
• Demand currents on a per phase basis.
• Instantaneous currents, including ground current.
• Instantaneous voltage on a per phase basis.
• Instantaneous frequency.
• Positive, negative, and zero sequence voltages.
• Instantaneous power factor on a per phase basis.
• Metering settings to include demand interval, and
alarm thresholds for current, single-phase kW, three­phase kW, single-phase kvar, and three-phase kvar.
Event Recorder
The Form 6-LS control contains capabilities to perform Sequence of Events time-stamping for up to 33 standard event types. Factory-defined event types include:
• Overcurrent Protection Trip
• External Trip
• Non-Reclose Trip
• External Close
• Lockout
• Reset
Sixteen additional inputs can be user-defined through the Idea Workbench.
Note: Seven of these additional inputs are already factory-

defined (default) for the Form 6-LS control.
Recloser Duty Monitor
The Form 6 recloser control software is equipped with a Recloser Interrupting Duty Monitor. The Duty Monitor accumulates the summation of I currents on each interrupter. This feature permits programmable entries to preset the duty of an existing recloser. The recloser duty monitor displays interrupting duty in percent of duty used. If the duty cycle monitor exceeds 100%, the recloser should be examined for maintenance.

for all interrupted
Discrete SCADA Communications
The control provides five configurable output status contacts and three configurable input control contacts as standard. Each status contact is configurable using graphical interface software to combine status functionality along with Boolean algebra. Default output status contacts are: Lockout, Recloser Open, Recloser Closed, Ground Trip Block, and Hot Line Tag. One output status contact is
a solid state output (SS1) with a pickup time no longer than
two milliseconds.
The control also provides a minimum of three configurable input control contacts. Each control contact is configurable using a graphical interface software. Contacts accept a
whetting voltage range of 12–250 VDC, 120/240 VAC.
Each digital input is configured for either a momentary, maintained, or maintained with precedence contact. Default input control contacts are: Supervisory Trip and Lockout, Supervisory Close, and Remote Trip and Lockout.
A Discrete Interface Board is also available as an acces­sory to provide an additional eight output status contacts and eight input control contacts. The expansion I/O board is completely user-configurable.
TCC Editor II
Coordination and actual time current modifications are available with a graphic interactive TCC Editor or similar graphical software.
The TCC Editor II includes a complete database of stan-
dard recloser industry time current curves (TCC), both
ANSI and IEC types, along with the ability to customize the TCCs with multipliers, constant time adders, or minimum response time adders. Also, the user is able to derive their own specific TCC through data point entry. Each modified time current curve can be identified with a user-customized name and is selectable for configuring the control. The grid and format for presenting the TCCs has a user-adjustable scale, including the option of presenting multiple TCCs in various user-configured colors.
Oscillography
Oscillography is provided to present current and voltage waveforms, along with protection element and recloser response status changes. Filtered and unfiltered data are provided for viewing.
The recorded values are super-imposed on the protection scheme, and the state or value at any point in the scheme is displayed. The user has the capability to move through the event and watch the response of every function. All analog signals, digital inputs, and contact outputs are monitored. Analog oscillography is displayed at 16 sam­ples per cycle.
Oscillographic data is recorded to analyze multiple events during a permanent fault or other event type. The oscillo­graphic data shows two cycles before the trigger point and
eight cycles after the trigger point (default).
Note: The configuration settings are programmable.
Oscillography automatically initiates trigger points for the following functions:
• Above Minimum Trip for Phase, Ground, and Sensitive
Ground Fault
• Single- and Three-Phase Overvoltage
• Single- and Three-Phase Undervoltage
• Over- and Underfrequency
• Trip Signal Issued
• Close Signal Issued

The Idea Workbench also gives the user the ability to perform logical functions with these variables by using a simple graphical user interface. Refer to ServiceInformation
S280-70-4(ProView4.X.X)orS280-70-21(ProView5.X.X) Form 6 Control Programming Guide for additional
information.
Over/Underfrequency Protection
The control includes two-stage operation for both underfrequency and overfrequency protection. A fixed time delay ranging from 0 to 100 seconds in .001 second increments is available for both over and underfrequency. A frequency restoration function, enabled or disabled by the user, is provided to allow the recloser to automatically close should frequency return to within configured settings for a user-settable time. Over/Underfrequency Protection is included as part of each protection profile.
Over/Undervoltage Protection
The control includes single-phase and three-phase under voltage tripping. The control also includes three-phase overvoltage tripping. Both over and undervoltage functions include a single-phase and three-phase pick-up setting; a single-phase and three-phase time delay setting ranging from 0 to 100 seconds.
Directional
Directional functionality is included to maintain system coordination from multiple sources, as well as circuit reconfiguration for each profile. Directional applies to phase, ground, and negative sequence protection, selected independently. A maximum torque angle has a range of
0–90 degrees.
Data Profiler
A fully-configurable data profiler is available which allows the user to collect information by sampling data at selectable intervals. These time-stamped values can then be viewed to determine weekly load profiles, daily harmonic disturbances or hourly voltage fluctuations. The number of days of information the data profiler can provide depends upon configuration parameters. Refer to ServiceInformation

Algorithm of an Accurate Fault Location for EHV/UHV Transmission Lines: Part I - Fourier Transformation Method", IEEE Trans. on PAS, Vol. PAS- 100, No. 3, March 1981, pp 1316-1323.
Sync Check
Sync Check is a permissive system used to qualify any close signal to the mechanism when enabled via the sync check settings. Sync check allows for closing for any combination of dead/live bus/line, and to perform anticipatory closing for a live bus/live line condition by calculating slip and anticipating the mechanism closing delay. In addition to the anticipatory close calculation, the sync check system performs verification of line and bus voltage magnitudes and frequencies to determine that they are within pre-determined ranges, and that the angular difference between the two systems is also within the pre­determined range. For a live/live close, where there is no slip between the systems, the sync check system allows permissive closing after the two systems are within frequency and voltage limits, and the angular difference between the systems has been within the allowable limits for a pre-determined time.
Sync Check functionality includes the following applications: Hot Line/Hot Bus Closing; Dead Line/Hot Bus Closing; Hot Line/Dead Bus Closing; and Dead Line/Dead Bus Closing.
Sync Check Parameters include the following configurable settings: Voltage Angle; Mechanism Operating Delay; Static Angle Delay; Dead Threshold; Live Threshold; Positive Sequence Dead Threshold; Upper Voltage Limit; Lower Voltage Limit; Lower Frequency Limit; Upper Frequency Limit; and Fail to Close Timer.
Manual Close Delay
Manual Close Delay provides a delay from the time that the manual CLOSE button is pushed to the time the manual close operation is performed.
The delay is programmable from 0 to 60 seconds in 1 second increments. A programmed delay value can be overridden for immediate closing by pressing the CLOSE button a second time.
An active Manual Close Delay can be canceled by pressing the TRIP/LOCKOUT button.
The default setting has the feature disabled (0 seconds). A
countdown on the front panel LCD screen indicates Manual Close Delay is active.

Communication Ports
The Form 6 control has two back panel communication ports and a front panel configuration data port.
The front panel configuration data port is described in the Operating Panel section of this manual.
There is one standard 9-pin RS-232 and one optional
communication port (RS-485, serial fiber, Ethernet wire or fiber or both) on the back operator panel, as well as a stan-
dard IRIG-B port for user time-syncing. See Figure 9.
Communication Protocols
Four communication protocols are available for the Form 6 control:
• Modbus
• DNP3
• 2179
• IEC870-5-101
One communication protocol can be selected for either the back panel RS-232 or the optional communication port.
All four protocols are selected and configured by the user with the ProView Communications Workbench application software.
Ethernet Communications
• ProView over TCP/IP
• DNP3 over TCP/IP
Ethernet connection allows for network application of the Form 6 control for both DNP3 and ProView protocols. In addition, the front panel data port can simultaneously communicate ProView to the PC.
Ethernet configuration is accomplished via ProView inter­face software. Refer to Service Information S280-70-4

Communicating with the Form 6 Control, for Ethernet Configuration information.
When a communication protocol is selected for the option-
al communication boards (serial fiber or the RS-485 serial port), the RS-232 serial port is defaulted to ProView inter-
face software protocol.
DNP3 is factory-defaulted to the RS-232 port.
When a communication protocol is selected for the RS-232
serial port, the optional RS-485 or serial fiber optic board
is not active.
The RS-485 or fiber optic serial ports do not support
ProView interface software protocol.
The user can simultaneously communicate to the Form 6 control using both the front panel data port and the appro-
priate back panel serial communication port (provided the
back panel RS-232 port or the Ethernet optional commu-
nications board is not configured to be ProView protocol).
Control Information
Control information includes firmware identification by cat­alog number and name, date code, and ProView release number. Control information is available through the
Settings menu on the front panel (Figure 4).

Form 6-LS Pole Mount Recloser Control Installation and Operation Instructions
INSTALLATION PROCEDURE
Initial Programming Prior to Installation
CAUTION: Equipment misoperation. Do not
connect this control to an energized recloser until
all control settings have been properly programmed and verified. Refer to the programming information for this control. Failure to comply can result in control and recloser misoperation, equipment damage, and per­sonal injury. G110.3
CAUTION: Equipment Misoperation. Check minimum trip values prior to changing an alternate profile. Failure to do so may cause misoperation of the recloser under load conditions. T280.1
IMPORTANT: Program all protection profiles. Unused alternate profiles should be programmed with the same settings as one of the applicable profiles. Default settings on unused alternate profiles can cause unnecessary outages if they are below normal system requirements.
The control must be programmed with all necessary operating settings, all alternate profiles, and parameters prior to operation with an energized recloser.
Note: Initial programming of the control is the responsibility of a
qualified technician or engineer familiar with control functions and programming parameters required for the specific recloser installation.
The control must be programmed with the Form 6 ProView interface software. Refer to ServiceInformationS280-70-4
(ProView 4.X.X) or S280-70-21 (ProView 5.X.X) Form 6 Microprocessor-Based Recloser Control Programming Guidefor additional information.
Note: The Pole Mounted Control checkbox in the ProView
System Configuration screen must be selected for all Form 6 pole mount controls. This includes both pole and substation applications.
IMPORTANT: Form 6-LS control users must activate the loop scheme default settings in the ProView application software Idea Workbench:
1. Click on LOAD IDEA WB STRUCTURE.
2. Select WBI-Form6-F6Default-LS.sch and click on
Open.
3. Click on READ IDEA WB SETTINGS FROM DISK.
4. Select WBI_Form6_Settings_F6 Default-LS.txt and
click on Open.
5. Enable the LS functionality by selecting the LS
Enable checkbox in the Loop Scheme Settings Dialog box located in the Idea Workbench Optional Loop Scheme Workbench.
Control / Recloser Compatibility
The Form 6-LS recloser control is adaptable to the following Kyle reclosers:
WE*, WVE27, WVE38X, VWE, VWVE27, VWVE38X, VSA12, VSA16, VSA20, VSA12B, VSA20A, VS012, VS016, NOVA15**, and NOVA27**.
* This control is not compatible with Form 1 Type WE reclosers
below s/n 300 and RE reclosers below s/n 400.
** Control-powered NOVA reclosers that are manufactured after
September 2004 require a Voltage Trip/Close (VTC) interface
for tripping and closing. This VTC requirement applies to three­phase control-powered NOVA reclosers with a Type A or a Type D mechanism and Form 5, Form 5 LS/UDP, Form 6, and Form 6 LS controls with the control-powered interface. These reclosers and controls are equipped with 19-pin control cable receptacles. Refer to RECLOSER VTC INTERFACE and CONTROL VTC INTERFACE sections of this manual for additional information.
Reclosers manufactured prior to June 1989 are equipped
with Type A bushing current transformers. These reclosers were designed for use with Form 2, Form 3, and Form 3A controls. Because the Form 6 recloser control is designed for use with reclosers equipped with Type B current­sensing Transformers, reclosers retrofitted with Form 6 recloser controls should be retrofitted with Type B current transformers. All reclosers manufactured since 1989 are
equipped with Type B (1000:1, 1000/500:1, or 2000:1)
sensing CTs.
Reclosers equipped with Type B sensing CTs are compatible with all Cooper Power Systems recloser
controls (Form 2, Form 3, Form 3A, Form 4A, Form 4C, FXA, FXB Form 5, and Form 6 recloser controls), and are
identified with the following label prominently displayed on the recloser sleet hood or the front of the operator cabinet:
NOTICE
RECLOSER IS EQUIPPED WITH TYPE B
SENSING CTs.
RECLOSER DOES NOT HAVE A BATTERY
CHARGER.
The Form 6 recloser control can be used with the old-style Type A CTs; however, the event recorder and duty cycle monitor will have limited accuracy for currents above 5000 Amps.
Retrofit kits with the new Type B sensing CTs are available to upgrade existing families of reclosers for operation with Form 6 recloser controls. For additional information, contact your Cooper Power Systems representative.
For identification, Table 1 lists the serial number breaks between old-style Type A and the new-style Type B sensing CTs. Below this serial number, the recloser is equipped with the Type A CTs.
Note: For reclosers shipped prior to June 1989 and not listed
below, please contact your Cooper Power Systems representative with the recloser type and serial number for verification of type A or B bushing current transformers.

(inches).
A hole and keyway in the control mounting bracket
accommodates a 15.9 mm (5/8”) bolt.
Locking the Control
The handles on the Form 6 control cabinet are able to accept a padlock to prevent unauthorized access. For cabinets with the quarter-turn latch, the top handle has two locking holes provided depending on the diameter of the lock shackle being used. Refer to Figure 10.
• Use the smaller hole for shackle diameters of .177-
295”.
• Use the larger hole for shackle diameters of .295-.394”.
Note: DO NOT use a smaller shackle (.177-.295) in the
larger diameter hole as it will NOT LOCK the cabinet.
Grounding the Control
WARNING: Hazardous voltage. Recloser and
control must be solidly grounded. Follow all locally approved procedures and safety practices when grounding this equipment. Improper grounding can result in contact with high voltage, which will cause death or severe personal injury. G115.1
The control cabinet must be grounded. A grounding connector on the underside of the cabinet will accommodate
No. 14 solid through No. 4 stranded conductors.
Suggested methods for grounding the control and recloser are shown in Figures 11 and 12.
Figure 11 illustrates grounding methods for 4-wire multi-
grounded systems with local supply voltage transformer.
Figure 12 illustrates grounding methods for 4-wire multi-
grounded systems with remote supply voltage transformer.
For effective surge protection, all control and power conductors for the Form 6 control must be routed parallel to a corresponding ground path. For example, the AC power supply for the control should be parallel to and equal in length to the transformer ground path. The control cable should be parallel to and routed close to the recloser ground path.

Form 6-LS Pole Mount Recloser Control Installation and Operation Instructions
Customer Connections for AC Power to Form 6-LS Control
DANGER: Hazardous voltage. Do not connect
potential transformer low-voltage secondaries to the control through cables or other wiring until the unit is installed in the field. Transformer high-voltage primary windings will become live when 120V AC is applied to the control from an alternate source if the transformer secondary is connected. Failure to comply may result in severe personal injury or death. T371.1
WARNING: Hazardous voltage. Before applying
power to the control, confirm that male pins of the input power receptacle are electrically insulated to prevent unintentional contact with 120V AC voltage. Failure to do so may result in severe personal injury or death. T372.0
CAUTION: Equipment damage. Do not drill
connection holes into the top of the cabinet.
Connection holes in the top of the cabinet will allow moisture to seep into the control and damage the components or cause control misoperation. Failure to comply will void the control’s factory warranty. T249.0
power supply accessory is available for communication equipment rated for 13.8 VDC. Refer to Radio Mounting Accessory in the Accessories section of this manual for additional information regarding the radio power supply. Some additional features are as follows:
• Positive LED indicator for power supply presence
• Self-protective fuse (5 amp, 250 VAC)
• 28 VDC whetting voltage for I/O contact inputs
IMPORTANT: Prior to energizing the control, the selector switch must be set as follows:
• For 120 VAC incoming power, the selector switch
must be set to the 115V position.
CAUTION: Equipment misoperation. Verify that
the 120/240 VAC selector switch is correctly set
for incoming voltage. Failure to comply may cause
misoperation (unintentional operation) of the control
and/or equipment damage resulting in personal injury. T278.0

Input power (120 VAC) to the Form 6-LS control is con­nected to Terminal TB8. B phase (H) is connected to TB8-
3. B phase (N) is connected to TB8-4. Y phase (H) is con­nected to TB8-9. Y phase (N) is connected to TB8-10. Refer to Figure 14.
Input power is required:
• To power the control
• To provide voltage and power metering
• To power the thermostatically controlled heater
• For the convenience outlet accessory
IMPORTANT: Delta connections are not used on the Form 6-LS control.
Power Supply / Battery Charger Board
CAUTION: Equipment damage Form 6-LS (Loop
Scheme). Do not connect 240 VAC to B or Y phases on terminal blocks TB7 or TB8. 240 Volts will damage
internal components and cause control misoperation. T314.0
Incoming AC power is routed to the Power Supply / Battery Charger Board. While this board is designed to
accept either 120 VAC or 240 VAC through a selector switch located directly on the board (Figure 13), the Form
6-LS control must be set for 120 VAC incoming power.
The battery charger includes a temperature-compensated design to optimally charge the control battery. The power supply / battery charger board also includes an auxiliary power supply for connection to communication equipment
(radios, modems, etc.). The auxiliary power supply is rated
28 VDC, 65 Watts peak. A separate 28 VDC to 13.8 VDC

Power Supply Board
Terminal Blocks
Two terminal blocks are used for connection to the Form 6-LS control. Both terminal blocks are fit for a #6 screw which can allow a maximum ring size for a #10 AWG for metering.
Terminal Block TB7 provides power to the Form 6-LS control and is directly connected to the power supply circuit board. Terminal Block TB8 is used to connect sensing transformer voltage. The wiring of the transformers should follow the application illustrations per Figure 15 or 16.
Loop Scheme
The Form 6-LS control is equipped with a transfer relay to provide power to the control and power to the recloser if either voltage is present on the source or load side of the recloser. The relay transfers the control power source from
Source I of the control to Source II (load side) upon loss of
source side voltage. This circuitry is rated for 120 VAC
operation only, and is connected to B and Y phases on
TB8 as Source I and Source II respectively. Transfer relay
output contacts connect to TB7. Refer to Figure 14.
Power Connections
The transformer required for power is 1kVA minimum.
Transfer relay connections are shown in Figure 14.

Communication Board Accessories
The Form 6-LS control is equipped with a Communication
Board Accessory (expansion bay) offering versatile support
for modern communication media. Six distinct communi-
cation options (Figure 26) are available, providing two-way,
real time digital communications with a remote terminal unit
(RTU), wireless, telephone modem, Ethernet network, or
other communication devices. The following options are available:
• No auxiliary communication card installed (standard)
• RS485 (isolated) Serial communication card
• Fiber-optic-based Serial Communication Card (ST)
• 10/100 Base-T dual Ethernet communication card (2*RJ-45)
• 100 Base-FX dual Ethernet communication card (2*MT­RJ)
• 10/100 Base-T, 100 Base-FX Ethernet communication card (RJ-45 + MT-RJ)
The expansion bay based Communication Board Accessory concept offers high versatility with respect to communica­tion medium and protocol support. Additional accessories are being continuously developed. Contact your Cooper Power Systems representative for the latest information regarding particular media and communication protocol support.
RS485 Serial Communication Card
The RS485 serial communication card accessory provides
means for establishing asynchronous link-based digital communications with the Form 6-LS control. The Galvanic
isolated (1000V DC) RS485 port uses a single shielded
twisted pair connection and can support 32 devices in multi-drop configuration. Communication speed is con-
trolled through software and can be set at: 1200, 2400, 4800, 9600, 19.2k, 38.4k, 57.6k, and 115kBPS.
Digital communications must be programmed through the Communications Workbench to ensure proper operation of
the RS485 communication card accessory. Refer to
Service Information S280-70-4 (ProView 4.X.X) or S280­70-21 (ProView 5.X.X) Form 6 Microprocessor-Based RecloserControlProgrammingGuidefor additional proto-
col support information.
Fiber-Optic Based Serial Communication Card
The Fiber-Optic based Serial Communication Card offers
means of establishing asynchronous (RS-232 like) digital
communications through multi-mode fiber media. The use of the fiber-optic based serial communication card acces­sory can enhance communication reliability, and provides excellent electrical isolation thus protecting transmitted data from extraneous electrical interference.
An optional fiber-optic-to-RS-232 converter with DB-9
connector (Catalog Number KME6-1875-1) is available for
interfacing between an optical signal and a hard-wired RS-232 signal, when required. This converter is compatible
with loop (ring) and point-to-point (star) configurations.
A pair of industry standard ST type fiber-optic connectors are mounted on the back of the board enabling customer connection to a digital communication system using fiber-
optic cables (customer-supplied).
The fiber-optic link has separate receive (RX) and transmit (TX) ports operating at 820nm. Typical transmission dis-
tance is 2000m with 62.5/125µm multi-mode fiber. Consult your Cooper Power Systems representative for availability of long haul solutions. Link communication speed is con-
trolled through software and can be set at: 1200, 2400, 4800, 9600, 19.2k, and 38.4k. Modbus can also be set at
57.6k.
The fiber-optic accessory must be programmed through the Communications Workbench for the appropriate proto­col. Refer to Service Information S280-70-4 (ProView
4.X.X) or S280-70-21 (ProView 5.X.X) Form 6 Microprocessor-Based Recloser Control Programming Guidefor additional information.
The fiber-optic based serial accessory includes TX and RX indicating LEDs for verifying communications along with an echo / non echo switch for supporting ring / star fiber topologies.
When operated in a ring configuration, the toggle switch must be set in the ECHO position. In this mode, the fiber-
optic card will repeat (pass through) all messages received
on the RX fiber, and will respond to the Master station by first echoing the incoming command and then sending the response. This arrangement is best suited for creation of low cost multi device fiber loops. For reliable communica­tions, the fiber loop system requires that all devices in the loop remain powered at all times, thus enabling unob­structed flow of information throughout the loop.
A more resilient system can be designed by using the fiber-optic ports in a point-to-point or multiple point-to-
point (star) configuration. For this mode, the toggle switch
must be set in the NON-ECHO mode. The Form 6-LS control will respond to the Master station by sending a
response only (total separation of Receive and Transmit fibers). Additional hardware (fiber-optic star coupler) is
required to support the multiple point-to-point device con­figurations.
Ethernet Communication Cards
The Ethernet communication card accessory brings the Ethernet network connectivity to the Form 6-LS recloser control platform. It is highly flexible, offering simultaneous
support for multiple sessions, device management (ProView over TCP/IP) and SCADA communications (DNP3 over TCP/IP).
By natively supporting a set of widely accepted industry standards (TCP/IP, UDP/IP, OSI) the Ethernet communica­tion accessory ensures seamless interoperability with other network devices.

The Ethernet communication card accessory is offered in 3
physical layer configurations (twisted pair and optical-fiber options) as shown in Table 10.
TABLE 10 Ethernet Communication Card Configurations
Card Output Communication Type Configurations Connectors Speed
1 10/100 Base-T 2 * RJ-45 10 / 100MBps (auto switching)

100 Base-FX and 100MBps
4 100 Base-FX, 2 * LC 100MBps (single-mode fiber) (full duplex)
Maximum link length is determined by the use of the particular physical layer implementation, and can be further constrained by the actual network configuration. In case of
the 100Base-FX MT-RJ connector based implementation,
maximum link length in excess of 2000m can be achieved with 62.5/125µm multi mode fiber. The fiber-optic link uses 1300nm wavelength, and can easily be interfaced to other
100Base-FX solutions (ST connector patch cord solution).
The Ethernet communication accessory card (Figure 26) is
equipped with two physical ports configured to act as primary and standby LAN connections. Availability of the backup communication port enables creation of highly redundant Ethernet networks thus increasing the overall system reliability.
Note: Under normal network conditions, all communications
will be channeled through the primary port (#1, Figure
26), with the standby port either logically disabled, or
configured for fast automatic throw-over in case of the primary Ethernet link failure. Refer to ServiceInformation

3. To power down the Form 6 control, unplug the battery
(disconnect the black/red battery connector).
4. Perform a battery charging cycle. Refer to Battery Charging in the Battery Test and Charging Procedures section of these instructions.
IMPORTANT: While the Form 6 control is powered in this manner, the control battery is being continuously discharged. When the battery voltage drops to 22V DC, the control will automatically power down.
If the battery is left in a discharged condition, the
battery(s) will sustain permanent irreversible damage.
Therefore, a battery charging cycle should always be
performed after this procedure to bring the battery(s)
back up to full charge.

Closing the Recloser During Testing
Electrical Closing – Solenoid-Operated Reclosers
Line voltage is required for automatic recloser operation during testing of reclosers equipped with a closing solenoid
(except for reclosers equipped with the low voltage closing accessory).
WARNING: Hazardous voltage. Interconnect
source leads X and Y and ground solidly to the
recloser tank (Figure 34). Do not connect lead Z to any
other phase or mechanical ground. Dangerous voltages to
ground exist on the phase connected to lead Z. Solidly
ground all equipment. Failure to comply can result in severe personal injury and/or equipment damage. T224.1
For on-line testing, bypass the recloser, open the load­side disconnects and keep the source-side disconnects closed. This will remove the recloser from service, but will
keep line voltage supplied to the closing solenoid (Figure
32).
WARNING: Hazardous voltage. The switchgear
(apparatus and control) and high-voltage trans­former must be in a test cage or similar protected area to prevent accidental contact with the high-voltage parts.
Solidly ground all equipment. Failure to comply can result in death, severe personal injury, and equipment damage. T221.5
For shop testing, the closing solenoid voltage is supplied by back-feeding a transformer with a low-side rating equal
to the voltage rating of an available power source, and a high-side rating equal to the voltage rating of the recloser (Figure 34). A 75 kVA transformer of the proper voltage rat­ing with an impedance drop of approximately 3% is satis­factory. The AC source must have a comparable imped­ance drop.
A test circuit for these solenoid-closed reclosers is shown in Figure 33. The following equipment is required for the recommended shop testing setup:
Note: Solenoid-closed reclosers equipped with a 120- or 240-
VAC low-voltage closing coil accessory can be tested as shown in Figure 35.
• Variable Autotransformer T1, 230 Volts, 20 Amps.
• Low-Voltage transformer T2 to simulate fault conditions.
Ratio and size will depend upon the maximum current
to be used. The recloser presents a low impedance to the transformer, so secondary voltage must be only high enough to force the required current through the secondary of the transformer and the recloser.
Note: An alternative method of providing the necessary
current through the transformer is shown in Figure
33.
• High-Voltage T3 to operate the closing solenoid.
The closing coil requirement is approximately 200 kVA
during the two-to-three cycle closing operation. The solenoid coil operating voltage must be maintained at the recloser bushings during the interval the closing coil is energized. This procedure is not used on reclosers equipped with the low-voltage closing accessory.
• Ammeter with a rating based on the level of test cur­rent.
• Current-actuated timer.

Low Voltage Closing Solenoid / NOVA Reclosers
WARNING: Hazardous voltage. Solidly ground
all equipment. Failure to comply can result in
death, severe personal injury, and equipment damage. T223.2
High-voltage is not required for reclosers utilizing a motor­operated closing mechanism, low voltage closing, or NOVA recloser. For information on energizing the recloser, refer to the appropriate recloser installation manual. Low
voltage supply can use either 120 or 240 VAC for input
power. Check the name plate on the recloser to verify the correct closing power requirements.
Figure 35 shows a test circuit for motor-operated, low­voltage solenoid-closing, and NOVA reclosers. Since these reclosers require only a low voltage source for closing, high-voltage transformer T3 and its protective cage is eliminated. All other equipment is the same as the test
equipment shown in Figure 34.

Manual Closing – Solenoid-Operated Reclosers
WARNING: Explosion Hazard. Excessive
Contact Arcing. Do not use the manual closing tool to close an oil-insulated energized recloser. Closing an energized oil-insulated recloser with a manual clos­ing tool can cause excessive contact arcing, rapid build-up of gas within the equipment, and possible explosion which can cause death, severe personal injury, and equipment damage. T203.2
If high-voltage for operating the closing solenoid is not available, manual closing can be substituted for electrical closing. However, not all control settings can be checked since manual closing is not synchronized with the closing coil control circuit in the control.
Follow these steps to manually close the recloser:
1. Remove the closing tool port cover and gasket from the side of the recloser head casting.
Figure 35. Suggested test circuit for motor-operated, solenoid­closing reclosers with low-voltage closing.
CAUTION: Equipment damage. Do not turn the manu­al closing tool more than one-quarter turn clockwise. Forcing the tool beyond the mechanism stop may shear the pin on the closing shaft of the recloser. T222.0
2. Insert the tee-handled tool (available as an accessory) into the port, engaging the pin on the closing shaft
(Figure 36).
3. Close the recloser by placing the yellow operating
handle (located under the sleethood) into the up or
CLOSED position and turning the closing tool one­quarter turn clockwise.
4. After each trip operation, about 1/2 second elapses while the closing solenoid plunger is moving upward to reset the main toggle latch.
5. After the main toggle latch resets, the recloser can be closed again by operating the manual closing tool.
6. Replace the gasket and port cover on the recloser head after testing has been completed.
