Additional information

These instructions cannot cover all details or vari ations in the equipment, procedures, or process described, nor provide directions for meeting every possible contin gency during installation, operation, or maintenance. When additional information is desired to satisfy a problem not cov ered sufficiently for the user’s purpose, contact your Eaton representative.

Product informationThe Form 7 recloser control includes hardware features including modular, flexible and scalable hardware operated with an 800 MHz quad-core processor, 1GB RAM, and 4GB flash storage. The control’s modular layout affords the ability to easily insert hardware as new applications arise and requirements change.

The Form 7 control’s powerful Workbench NXG is a highly intuitive graphical user interface that simplifies training and operator familiarity. Workbench NXG logic is fully transparent with powerful logic tools available to customize control functions or create powerful, unique applications.

The control includes an array of integrated security tools for the user to prevent local intrusion or unauthorized operation. These security tools include Role-Based Access Control (RBAC), signed firmware, a user audit log, and an optional door alarm accessory that provides feedback when the door is closed, opened, or if the switch is disconnected. Transport Layer Security (TLS) encryption tools can be utilized to establish a secure, private communications channel or SCADA traffic and remote connection to ProView NXG.

As ordered, the control is powered from either 120 or 240 Vac.

ANSI standardsEaton Cooper Power Series reclosers are designed and tested in accordance with the following ANSI standards: C37.60 and C37.85 and ANSI Guide C37.61.

Quality standardsAll Form 7 controls are manufactured in ISO 9001 certified production facilities.

Acceptance and initial inspectionEach Form 7 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 storageBe 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.

ote: N To energize the control, supply AC power to input terminal block TB7. This terminal block is mounted on the lower left of the back panel.

Control battery

The 24 Vdc Form 7 recloser control battery is fully charged prior to shipment and is ready for use.

The control is shipped with the battery not installed.

Remove the battery from the Control before transporting the Control. Do not transport a Form 7 control with the battery inside the control enclosure.

The battery shall be installed only after the control has been mounted.

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 affects battery life. Store sealed lead acid batteries fully charged and at room temperature. Never store lead acid batteries at temperatures exceeding 117 °F (47 °C). Storing the battery for any time above 117 °F (47 °C) can result in approximately one month of shortened life.

After three months of storage (from the previous test date), test and then charge the batteries for 24 hours. Catalog Number KA43ME7001 is a 120-Volt battery charger used to provide an external source of charge for the control’s 24 Vdc battery (two 12 Vdc batteries).

2 INSTALLATION AND OPERATION INSTRUCTIONS MN280095EN February 2022


IMPORTANT: Connect the control battery before AC power is connected to the control’s AC supply Input Terminal Block. The battery must be disconnected and removed prior to shipping. The battery must be disconnected prior to storing the control. See Figure 13.

ote: N When shipped from the factory, the battery will be in the same carton as the control. The battery leads will be taped to the battery casing. Connect the battery plugs into the mating connectors to complete the battery circuit.

Dispose expired batteries in an environmentally responsible manner. Consult local regulations for proper battery disposal.

FORM 7 CONTROL DESCRIPTION

DescriptionThe Form 7 control is designed for use with NOVA NX-T reclosers to provide protection, metering, and automation of distribution feeders in substation and line applications. The control operates the individual reclosers representing phases A, B, and C.

ote: N The phase sequence positions (phase A, B, and C) are independent of each other.

The Form 7 recloser control includes extensive system protection functionality including:

Phase, ground, and negative sequence overcurrent protection

Over/under frequency and voltage protection

Directionality

Sync check

Analysis tools are provided to empower the user’s ability to respond to events occurring on their system. These tools include fault locating, event recording, Workbench NXG, and oscillography.

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.

Use the front panel LCD display to:

Configure the operating settings for the control

Display metering, counter information, control parameters, and alarms

Provide diagnostic information

With Form 7 NXG interface software, you can perform control programming, interrogation, and operations. Install the software on a personal computer and connect it to the control’s front panel through the USB or Ethernet port.

The NXG interface program software includes additional functions used to create and graphically display Time Current Curves, and provides the Workbench NXG for configuring user-selected inputs and outputs, configurable event and alarm data, and selectable communication points for serial and Ethernet 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.

Theory of operationA functional block diagram of the Form 7 control is shown in Figure 1. Current sensing is provided by three current transformers located in the recloser and interfaced to the Form 7 control through the control cable. The control cable also supplies the Form 7 with the trip and close signals, the recloser status, and provides a connection to the Recloser Interface (RIF) module that provides isolation and reliable operation. Voltages for metering are connected to the voltage data acquisition (DAQ) module through connectors P251 and P252. If PT (potential transformer) sensing is being used, the signals are first routed through the PT sensing board and connected at TB8.

Line current flowing through the recloser is measured by the integrated current transformers and then converted by the DAQ module to a digital signal suitable for metering and fault current calculations. Data sampling occurs at a rate of 128 samples/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. 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.



Figure 1. Form 7 recloser control operational flow diagram

Phase operation

The Form 7 control uses three modes of operation that are configured through the ProView NXG user interface software or LCD Front Panel.

In Three-Phase Trip, Three-Phase Lockout (ganged) mode, all three phases will simultaneously trip and close due to a protection event or user command.

In Single-Phase Trip, Three-Phase Lockout mode, all three phases will trip and lockout when one of the phases sequences to lockout. While the phases will operate independently within their sequence the protection parameter programming is shared between all three.

In Single-Phase Trip, Single-Phase Lockout mode, each phase independently sequences to lockout. The protection parameters are still shared between the phases in Single-Phase Trip, Single-Phase Lockout mode.

The yellow handles on the triple single recloser can be manually operated to open and lockout a phase. If the device is in the following modes and any handle is pulled, all three phases will open and lockout:

Three-Phase Trip, Three-Phase Lockout mode

Single-Phase Trip, Three-Phase Lockout mode

If the device is in Single-Phase Trip, Single-Phase Lockout mode, only the phase whose handle is pulled will trip and lockout.

The NOVA NX-T recloser’s mechanical blocking feature prohibits the phase to be closed with its handle pulled down. The open signal to trip and lockout the device is sent from the Form 7 control.

WARNINGHAZARDOUS VOLTAGE. DO NOT RELY ON THE OPEN POSITION OF THE YELLOW OPERATING HANDLE; IT DOES NOT ENSURE THAT THE LINE HAS BEEN DE-ENERGIZED. ALWAYS ESTABLISH A VISIBLE DISCONNECT. FAILURE TO FOLLOW PROPER SAFETY PRACTICES CAN RESULT IN CONTACT WITH HIGH VOLTAGE, WHICH WILL CAUSE DEATH OR SEVERE PERSONAL INJURY.

IMPORTANT: Pushing the yellow operating handle to the CLOSE position will not close the recloser. All close operations are initiated by the Form 7 control.

Ground operation

Ground overcurrent operation will mirror phase overcurrent operation when the device is in Three-Phase Trip, Three-Phase Lockout mode.

In Single-Phase Trip, Three-Phase Lockout and Single-Phase Trip, Single-Phase Lockout modes, ground tripping is only active when all three phases are closed. Ground tripping is disabled during the reclose interval of any one phase.

For faults above the ground minimum trip value, and below the phase minimum trip value, all three phases trip on ground and advance to the next sequence position.

For faults above the phase and ground minimum trip value, the control trips on the phase(s) above phase minimum trip, operating on the phase or ground TCC, whichever is faster.Only tripped phases advance in sequence and are counted as phase operations.

Phase/ground sequencing

Phase and ground share the same sequence position. As the position sequence advances, the phase and ground TCCs advance together to maintain proper coordination with upline and downline devices. This is applicable for temporary and permanent faults including faults on multiple phases.

Front panelThe Form 7 control front panel is illustrated in Figure 2. Use the LCD screen and keypad for programming the control and viewing its status. The right portion of the panel is used for operating the control and recloser.

If no key is pressed within fifteen minutes, the Power Save feature turns off the backlit LCD display and most LEDs (except Hot Line Tag).

ote: N Enable or disable the Power Save feature through the ProView NXG interface software. The default setting is “enabled.”

HOT LINE TAG ON/OFF

The Form 7 control default configuration is with a membrane pushbutton for TRIP, CLOSE, and Hot Line Tag. Optional mechanical pushbuttons for TRIP and CLOSE and a toggle switch for Hot Line Tag are available. See Figure 4 and Figure 5.

WARNINGHAZARDOUS 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.

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.

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.

Figure 4. Membrane TRIP (Lockout) and CLOSE buttons, and Hot Line Tag button and indicator LEDs

Figure 5. Mechanical TRIP (Lockout) pushbutton; CLOSE pushbutton; Hot Line Tag switch and Hot Line Tag red indicator LEDs

IMPORTANT: If the Front Panel Inactivity Time Delay is enabled (default) and Hot Line Tag is active, the Hot Line Tag LED will not turn off when the inactivity timer is reached.

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 Hot Line Tag function from the operator panel, either press the membrane button or flip the optional toggle switch up to the ON position. The LED indicator illuminates when the function is active.

Default configuration for the Hot Line Tag function permits it to only be reset by the source that 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. If Hot Line Tag is set remotely the HLT LEDs will continually flash and will not be able to be reset from the operator panel. The flashing indicates to the user that HLT was set by a remote source, and this source can be seen through the Front Panel HLT menu. This functionality can be configured further in Proview NXG. Refer to the Form 7 Programming Guide for additional information.

TRIP (Lockout) pushbutton

The TRIP button provides front-panel access to trip (lockout) the recloser. When pressed, the TRIP pushbutton opens the recloser and locks out the control. Options for the button include a membrane button or a mechanical pushbutton. See Figure 4 and Figure 5.

CLOSE pushbutton

When pressed, the CLOSE button returns the control to the initial or home sequence position, closing the recloser. The control is then ready for the start of a new trip/close sequence. The close operation can be delayed by a user configurable time (see Manual close delay on page 10). Options for the button include a mechanical pushbutton or a membrane button (see Figure 4 and Figure 5).

ote: N A Close Malfunction alarm must be reset before Closing will be allowed.

ote: N Pressing the CLOSE button 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 Workbench NXG feature in ProView NXG.

If the recloser is closed, pushing and holding the CLOSE button does not activate the Cold Load Pickup feature. See Cold load pickup on page 8 in the Features section of this manual.

Function keys and LEDs

Function keys provide quick access to frequently operated Form 7 control features (Figure 6). Each key has a red LED that indicates 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.

Figure 6. Form 7 control operator panel one-touch function keys

GND TRIP BLOCKED: The Ground Trip Blocked function blocks all ground protection in the control for the active profile. This red LED lights when Ground Trip Block is activated from the serial port, Ethernet communications, I/O, the interface software, or locally from the front panel.

NON RECLOSE: The control is operating in a non-reclosing mode when the NON RECLOSE red indicator is illuminated. Non-reclosing mode disables any automatic reclosing operations.

Non-reclosing does not alter the active TCC. Activation is possible from the serial port, Ethernet communications, I/O, the interface software, or locally from the front panel.

SUPERVISORY OFF: When the SUPERVISORY OFF red indicator is illuminated, supervisory commands are blocked. Supervisory functions through the serial and Ethernet communications ports and the discrete I/O are blocked. Proview NXG communications through the Ethernet port remain active independent of the status of the SUPERVISORY OFF switch. Activation of this function key is restricted to locally from the front panel. 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.

A PHASE SELECT, B PHASE SELECT, C PHASE SELECT: The Form 7 control, when in Single-Phase Trip/Single-Phase Lockout mode, has phase selection keys available for the user to indicate which phase(s) of the triple-single recloser will operate when the manual TRIP (LOCKOUT) and CLOSE pushbuttons on the Form 7 operator panel are pressed. When the TRIP or CLOSE buttons are pressed, only the phase(s) that are selected (LED on) will trip or close.

OPTION 1–9: The OPTION function keys must be programmed using the ProView NXG software. These options do not have active default values. OPTION LEDs are illuminated when the options configured via the Workbench NXG are selected. Refer to the Form 7 Programming Guide 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.

ALT PROFILE SELECT: Displays the ALT PROFILE SELECT menu.

PUSH BUTTONS LOCKED: To lock all pushbuttons except TRIP, CLOSE, and HOT LINE TAG, press and hold PUSH BUTTONS LOCKED for 4 seconds. To unlock, press and hold PUSH BUTTONS LOCKED for 4 seconds.

FeaturesThe following control features and accessories are standard on the Form 7 recloser control.

Control security

To limit the programming and viewing to authorized personnel, the control provides more than 10 user-configurable password and username combinations.

Time current curves (TCC)

Time-current curves are available for numerous functions, including fast and delayed operations for phase, ground, and negative sequence protection. Each time-current curve is selected from 51 curves (includes IEC, IEEE, and SEL curves) which can be further customized by the user.

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 0.001 increments.

Time Adder with a range of 0 to 30 seconds in 0.001 second increments.

Minimum Response Time with a range of 0.01 to 1 seconds in 0.001 second increments.

High Current Trip multiplier with a range of 1 to 32 multipliers in increments of 0.001.

High Current Trip Time Delay with a range of 0.01 to 0.150 second in 0.001 second increments.

Time Dial Reset coefficient with a range of 0.000001 to 30 seconds in 0.000001 second increments.

Sequence coordination

Sequence Coordination eliminates nuisance tripping due to miscoordination with downstream devices. It allows the control to step through selected operations in the operating sequence without tripping. The control will step forward in the operating sequence when it detects a down-line device has operated. The number of Sequence Coordination advances is programmable from one to three operations and 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.

High current lockout

The high current lockout (HCL) feature automatically places the control in lockout when the current exceeds a programmed threshold on phase, ground, or negative sequence. On each of the protection profiles, the value for High Current Lockout can be set for operation one, two, or three. The control is placed in lockout if the current exceeds the programmed value during the present operation.

Thermostatically controlled heater

The control has a standard 100 Watt thermostatically controlled heater (ON 70 °F, OFF 85 °F) for humidity control and is voltage input independent. The heater is powered by 120/240 Vac from the power supply board.

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 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, three-phase kW, single-phase kvar, and three-phase kvar.



Event recorder

The Form 7 control can perform Sequence of Events timestamping. This includes both factory and user defined Sequence of Events. Program user-defined user defined Sequence of Events (inputs) through the Workbench NXG.

There are currently over 160 factory defined event types including:

Overcurrent Protection Trip

External Trip

Non-Reclose Trip

External Close

Lockout

Sequence Reset

The Event Recorder saves the last 1500 events and the last 50 events are viewable from the Form 7 LCD. Refer to the Form 7 Programming Guide for additional information.

Discrete SCADA communications

The control provides two output status contacts and two input control contacts as standard.

By default, the output and input contacts are not configured. Use the Proview NXG Workbench to program these contacts to perform specific operations.

Each control contact input is explicitly configurable (no default configuration) using the Proview NXG Workbench. Contacts accept a whetting voltage range of 12 – 250 Vdc, 120/240 Vac. Each digital input can be configured as a momentary, maintained, or maintained with precedence contact within ProView NXG Workbench.

Removable inserts

Removable inserts are included with the control to allow customization for specific protection requirements. Inserts are available for the status LEDs, and the operator panel function keys. The removable inserts are designed for use without adhesives, label makers, or temporary labels. Refer to the Change removable inserts section in this manual for more information.

Workbench NXG

The Workbench NXG provides access to various inputs, intermediate variables, and internal Form 7 alarms, status, and targets to allow user customization of the Form 7 recloser control to meet specific and unique applications. The Workbench NXG also gives the user the ability to perform logical functions with these variables by using a simple graphical user interface. Use of the Workbench NXG is not a requirement for operation.

Refer to the Form 7 Programming Guide for additional Workbench NXG information.

Over/under frequency protection

Six levels of frequency protection are included with the control. Each level is configurable as either overfrequency or underfrequency. Overfrequency and underfrequency are included as part of each protection profile.

A frequency protection restoration function can be enabled by the user. This function allows the recloser to automatically close if the frequency returns to within the user-configured frequency band during the user-specified time.

Over/under voltage protection

The Form 7 control provides the following voltage protection features:

Under-voltage (27) for single-phase and three-phase with capability of single-phase operation

Over-voltage (59) for single-phase and three-phase

Negative Sequence Over-voltage (59Q)

Zero Sequence Over-voltage (59N)

A voltage protection restoration function can be enabled by the user. This function allows the recloser to automatically close if the voltage returns to within the user-configured voltage band during the user-specified time.

Directional

Directional functionality is included to maintain system coordination from multiple sources, as well as circuit re-configuration for each profile. Directional applies to phase, ground, and negative sequence protection, selected independently. The maximum torque angle has a range of –90 to +90 degrees.

Fault location

The Form 7 control includes a fault location feature that estimates the distance to a fault. This feature uses the reactance method of fault location. This method considers the ratio of the difference between the measured reactance and the source impedance relative to the reactance of the entire line and estimates the distance to the fault.

Sync check

The Form 7 control includes sync check functionality. Sync check enables permissive close supervision based on the user configured 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 predetermined ranges

Checks that the angular differences between the two systems is also within the predetermined range



Sync check parameters include the following configurable settings:

Voltage angle

Mechanism operating delay

Static angle delay

Dead threshold

Live threshold

Upper voltage limit

Lower voltage limit

Upper frequency limit

Lower frequency limit

Fail-to-close timer

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. The data recorded is placed in a data table that can be exported to an external CSV file for further review (outside of ProView NXG).

Refer to the Form 7 Control Programming Guide for additional information.

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.

Abbreviated sequence (79AS)

Abbreviated Sequence (79AS) is a function that can be enabled by the user to advance the start of the reclosing sequence to a later position, as selected by the user. Abbreviated Sequence (79AS) must be enabled and unblocked for the sequence position to be advanced.

Abbreviated Sequence applies to any overcurrent protection function that relies on the reclosing (79) sequence position to determine operation settings such as TCC curves, number of shots to lockout, etc.

Switch-onto-Fault (SOTF)

The “Switch-onto-Fault” (SOTF) feature is a setting that allows the control to differentiate between close protection between re-energizing large loads (CLPU) and re-energizing when a fault is still present on the line.

Switch mode

Switch Mode is an additional targeting element within the Form 7 control, which allows the configuration of a separate pickup value (for Phase and Ground) that will set the control’s fault targets when pickup is exceeded.

An inrush blocking feature is available which allows a temporarily increased pickup level for phase current and blocking of ground targeting entirely for a specified time after recloser closure.

The Switch Mode element shall run in parallel with all other protection functionality programmed into the Form 7 control.

Sectionalizer mode

Sectionalizer Mode allows the recloser to operate as a sectionalizer. The Form 7 control can be programmed to count faults interrupted by an upstream recloser, and then isolate a fault section downstream from the Form 7 control’s location when the number of programmed fault interruption counts to lockout is reached.

The Form 7 control provides two independent sectionalizer elements (element 1, element 2) that count the non-directional/directional/dual directional faults, in coordination with other recloser elements, in the Form 7 control and the distribution system.



Breaker failure

Breaker failure protection is provided as a failsafe means of detecting if the connected recloser was not able to clear the fault it was intended to trip on. A breaker failure signal is generated by the Form 7 control if it sends a trip command, but sees the recloser remain closed.

The breaker failure signal can be mapped to an output contact I/O for a local backup breaker or recloser to clear the fault in the event the connected recloser is unable to clear the fault.

Non-volatile mode controls

The Form 7 control provides Non-Volatile Mode Controls (NVMC) to block and unblock various protection elements and control functions at run-time. Configuration options are provided to tailor NVMC operation to specific applications, including configurable profile dependence. The default NVMC logic allows only those elements and functions that have been enabled and configured in the active protection profile to be unblocked or blocked by user commands, SCADA commands, or Workbench logic. The NVMC logic stores block/unblock status for each protection profile by default, but can be configured to use a single block/unblock status across all profiles for specific control modes, if desired.

Communications

Communication ports

On the CPU board, the standard Form 7 control has the following standard ports (see Figure 7):

9-pin RS-232 port

USB 2.0 ports (3): Two ports are type A and serve as USB host ports. The other port is type B and serves as a USB device port. One host port and one device port are brought out to the inner swing panel for easier access. USB 2.0 host and device ports

Ground the control

WARNINGHAZARDOUS 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

Solidly ground the recloser and control. Ground the control by grounding the control cabinet. A grounding connector on the underside of the cabinet accommodates No. 14 solid through No. 4 stranded conductors. Refer to Figure 9, Bottom View, for ground lug location.

Suggested methods for grounding the control and recloser are shown in Figure 10, Figure 11, and Figure 12.

Figure 10 illustrates grounding methods for 3-wire ungrounded and 4-wire multi-grounded systems with local supply voltage transformer.

Figure 11 illustrates grounding methods for 3-wire ungrounded and 4-wire multi-grounded systems with remote supply voltage transformer.

Figure 12 illustrates grounding on a 3-wire uni-grounded system.

For effective surge protection, route all Form 7 control and power conductors 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.

Grounding with a local supply voltage transformer; 4-wire multi-grounded, 3-wire ungrounded, or impedance-grounded

Installation of a Form 7 control and NOVA NX-T system must include the following:

Protection of the recloser bushings and the supplying transformer with lightning arresters

Grounding of all recloser head(s) and tank(s)

Grounding of the transformer tank

Grounding of the control cabinet

Grounding of the SCADA equipment

IMPORTANT: All external inputs to the Form 7 control must be routed within 8 inches of their corresponding ground. During a surge, a potential of approximately 1.5 kV per foot can develop in the conductors. Differences between conductor and ground path lengths can add additional stress to the control components in the event of a power surge.

4-Wire multi-grounded systems

IMPORTANT:In pole-mounted applications, a ground connection must be made between the recloser, transformer, recloser control, and SCADA equipment for proper protection of the equipment. The pole ground must be sized per local utility practices to minimize the impedance between the recloser and the control.

3-Wire ungrounded and impedance grounded systems

The use of a grounding mat may be required depending upon the local safety regulations defining the permissible step and touch potential levels. Consult local regulations for proper grounding procedures

Grounding with a remote supply voltage transformer; 4-wire multi-grounded, 3-wire ungrounded, or impedance-grounded

Installation of a Form 7 control and NOVA NX-T system with a remote supply voltage transformer must include the following:








Figure 10. Recommended grounding for control installed on 4-wire multi-grounded, 3-wire ungrounded, or impedance-grounded systems with local supply voltage

IMPORTANT: In pole-mounted applications, a ground connection must be made between the recloser, transformer, recloser control, and SCADA equipment for proper protection of the equipment.

Input power to the Form 7 recloser control can be connected to an optional fuse at the terminal block. Incoming power connects to terminal block TB7. Transformer voltages used for metering will connect to terminal block TB8 (and are fused at the terminal block).

For single-phase 120 Vac or 240 Vac voltage supply, connect to TB7 as shown in Figure 16. For three-phase voltage supply, connect to TB8 as show in Figure 17. For 240-Volt, 3-wire transformer connection refer to Figure 20.

Input power provides:

Power to the Form 7 recloser control

Voltage and power metering

Power to the thermostatically controlled heater

Power to the convenience accessory outlet

Power supply (battery charger)

Incoming AC power is routed to the power supply. The power supply is configured at the factory based on the customer order and accepts either 120 Vac or 240 Vac (see Figure 14). The power supply’s battery charger is temperature-compensated to optimally charge the control battery. The power supply also includes an auxiliary power supply for connection to communication equipment (radios, modems, and so on). This auxiliary power supply is rated at 40 W continuous, 75 W peak. The 13.5 Vdc output between TB9 pin 4 (+) and pin 5 (–) on the power supply is rated for maximum continuous output of 17.25 W at 13.5 Vdc. Use shielded wire whenever making connections to the auxiliary power supply. Additional features include:

Positive LED indicator for power supply presence

Use of factory configured 120 Vac or 240 Vac for multiple transformer connections

Self-protective fuses (5 A, 250 Vac): FU1 and FU2

Whetting voltage (28 Vdc) for I/O contact inputs. Refer to Figure 23, TB9, Pin 1 (+) and Pin 2 (–)

Battery test and charging proceduresThere are different battery test and charging procedures for an installed battery versus an uninstalled battery (one that has been removed from the control).

Installed battery test

Follow the procedure below to perform a battery test in the Form 7 control. The values in the test procedures are based on testing at 77 ºF (25 ºC).

This procedure checks the condition of the Form 7 control battery using the Battery Test function on the BATTERY MENU (no external current/voltage meter is necessary for testing):

Alarm Conditionsote: N During a manual battery test a 5 Ω, 55-watt resistor is

placed across the battery terminals for approximately 5 seconds. The Form 7 control measures the battery voltage, if the voltage drops below 22.8 Vdc for one full second, the ALARM LED (battery alarm) is illuminated.

ote: N When the Form 7 control is disconnected from AC power and the control battery drops below 23.5 Vdc for 60 seconds, the ALARM LED will illuminate. If the battery voltage continues to decay and drops below 22 Vdc, the Form 7 control will shut down.

ote: N The battery test is blocked for 30 seconds upon power up of the control.

ote: N AC power can be either connected or disconnected for battery test.

ote: N If the battery voltage drops below 19 V, the battery must be charged by the external battery charger KA43ME7001.

Return the control to service


After the required work is completed, disconnect the control from the test set and follow this procedure to return the control to service:

1. While still in the service shop, appropriate personnel must verify that all control settings are correct.

2. Reconnect the ground cable to the control.

IMPORTANT: Equipment misoperation. Disconnect all control power sources prior to disconnecting or reconnecting the control cable from the control. Failure to comply can result in recloser misoperation at the time of disconnection or reconnection of the control cable to the control.

IMPORTANT: Prior to reconnecting the control cable, verify the control was removed from service in the exact order specified in the Remove the control from service section of this manual.

3. Control cable properly connected and supported.

4. Plug in the control battery.

ote: N The Form 7 recloser control will not power up until AC power is applied.

5. Apply AC power to the control.

6. Disable GND TRIP BLOCKED.

7. Verify the control clock is set to the current time after AC power has been reapplied.

ote: N The control clock may require resetting if the operating power has been disconnected for more than thirty days. Refer to the Form 7 Programming Guide for information on setting the control clock.

OPERATION

Modes of operationThe control has three modes of operation:

Three-phase trip and three-phase lockout (ganged)

Single-phase trip and three-phase lockout

Single-phase trip and single-phase lockout

Configure the mode of operation through the ProView user interface software. With the exception of the trip, operation is similar for the Three-Phase Trip and Three-Phase Lockout (ganged) and the Single-Phase Trip and Three-Phase Lockout.

Three-Phase Lockout

If the control is in Three-Phase Trip and Three-Phase Lockout (ganged) mode or Single-Phase Trip and Three-Phase Lockout mode, all three phases are permanently selected and the A PHASE SELECT, B PHASE SELECT, and C PHASE SELECT LEDs light. When one phase is opened with the yellow operating handle, all three phases open and lockout. The OPEN and LOCKOUT indicator LEDs light (on the control panel). With the yellow operating handle of the appropriate phase in the CLOSE position, press the CLOSE pushbutton on the control operator panel. All three phases close and the CLOSED LED lights.

Single-Phase Lockout

When in Single-Phase Trip and Single-Phase Lockout mode, any combination of phases can be selected and the respective PHASE SELECT LED lights. Each selected phase must be closed individually. When the selected phase is opened with the yellow operating handle, only that phase opens and locks out. The LOCKOUT, OPEN, and CLOSED indicator LEDs blink (on the control panel). The default text message on the LCD displays the mode of the triple-single configuration and the status of each phase. With the yellow operating handle of the selected phase in the CLOSE position, press the CLOSE pushbutton on the control panel. The phase closes and the CLOSED LED lights.



IMPORTANT: If the Front Panel Inactivity Time Delay is enabled (default), and more than fifteen minutes has elapsed since the last panel operation, all the LEDs except HOT LINE TAG (if active), Alarm, Control OK, AC power, Battery, and recloser status will turn off. Verify the phase or phases you want activated are selected prior to pressing the TRIP or CLOSE button.

Operation upon loss of AC powerThe 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 at 68 °F (20 °C). If AC power has not returned during this period, the control disconnects the battery from the circuit.

ote: N 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.

IMPORTANT: 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 the Form 7 Programming Guide for information on setting the control clock.

Maintaining battery charge (loss of AC power)

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.

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 is a 120-Volt battery charger used to provide an external source of charge for the control’s 24 Vdc battery (two 12 Vdc 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 and removed prior to shipping. The battery must be disconnected prior to storing the control. See Figure 13.

These communication cards can be installed in expansion bay 4, 5, 6 or 7. However, Ethernet fiber communication cards (single-mode or multi-mode) can only be installed in expansion bay 4 or expansion bay 5 only. There are no install bay limitations for the other available communication cards.

To install a communication card, the Form 7 control must be powered down. Remove the bay cover (secured with two screws) for the desired expansion bay (4, 5, 6 or 7) and insert the communication card into the bay using the internal guide rails. Afterward, power on the Form 7 control, and either enable the desired expansion bay through the HMI, or via ProView NXG. Refer to the Form 7 Cybersecurity and Communications Guide for further details on how to configure specific communication settings.

See Figure 33 for additional communication card options available.



Figure 33. Additional Form 7 serial and Ethernet communication options

Auxiliary contact I/OAvailable as an accessory, an optional auxiliary contact I/O card can be installed in auxiliary bay 1, 2, or 3. These auxiliary bays are vertical full bay slots, designated from left to right, and are located to the right of the voltage sensing bay. Up to three auxiliary contact I/O cards can be installed in the Form 7 module (either at factory or via a field service kit).

Each auxiliary contact I/O card has four contact inputs, four contact outputs, and one solid-state output contact.

An overlay is displayed on the faceplate of each auxiliary contact I/O card for easier contact I/O identification. By default, each contact input and output is unassigned, and can be configured using ProView NXG software. When in an enabled bay, each auxiliary contact I/O status is shown via the Form 7’s human-machine interface (HMI), ProView NXG software, or via SCADA.

To install an auxiliary contact I/O card, the Form 7 must be powered down. Remove the bay cover (secured with two screws) for the desired auxiliary bay (1, 2, or 3) and insert the auxiliary contact I/O card into the bay using the internal guide rails. Afterward, power on the Form 7 control, and enable the desired auxiliary bay through the HMI, or via ProView NXG.

Refer to the Form 7 Programming Guide for further details bay enablement and how to configure native and auxiliary contact I/Os using ProView NXG Workbench. See Figure 38 for shielding and surge protection wiring for supervisory and remote cables for auxiliary contact I/O.

See Figure 34 for example of two auxiliary contact I/O cards (with terminal block removed from top card), and Figure 35 for auxiliary contact I/O faceplate labeling.

Loop scheme accessoryThe Form 7 control includes a Loop Scheme (LS) feature for use in distribution feeder loop sectionalizing schemes in feeder applications to improve distribution system continuity through load-transfer and loop-sectionalizing schemes.

When the Form 7 control senses a loss of voltage, the control shall perform the programmed LS action to restore service to the affected feeder. The loss of voltage sensing can be accomplished via customer-supplied potential transformers or via recloser’s voltage sensors (internal and integral).

The control will perform its programmed LS functions after a programmable time delay when loss of voltage occurs. The control can be programmed for either sectionalizing or tie mode of operation.

The Form 7 control can change the protection scheme upon an LS action. Each protection profile (up to eight profiles) can be configured differently, and LS programming can be easily accomplished for sectionalizing or tie applications via

the Form 7 front panel HMI or through the Loop Scheme settings dialog window within ProView NXG.

When ordered from the factory, the control shall have LS inserts and LS test switches installed at the factory, in addition to default Loop Scheme settings file applied to the control.

See Figure 36 for Form 7 control’s front panel with LS inserts installed.

Figure 36. Form 7 front panel with LS inserts

See Figure 39 through Figure 44 for reference Loop Scheme wiring diagrams.

Incoming power receptaclesThe Incoming Power Receptacle allows the user to plug the power cable into the control thereby eliminating the need for hardwiring. Various options are available based upon the input power voltage and phase sensing requirements. Table 6 includes the available input receptacles for the control.

Figure 37. Form 7 recloser control input receptacle locations

Cable locking sleevesTo prevent detachment of the control cable from the control cabinet by unauthorized personnel, a cable-locking sleeve is available to enclose the cable plug. The plug is passed through the sleeve and the sleeve is then fastened from inside the control cabinet. There is no access to the cable receptacle without opening the locked cabinet door and detaching the sleeve.

Stainless steel cabinetA cabinet constructed from AISI 304 stainless steel is available as an accessory.

120 Vac GFI duplex outletThe GFI Duplex Outlet is provided in controls powered by 120 Vac. This convenience outlet is rated for 15 A and is accessible through the front door in the control cabinet. The 120 Vac GFI Duplex Outlet is used for many applications such as power for the MET Tester, auxiliary measurement equipment, and supplemental lighting. This accessory is standard for the Form 7 control when configured for 120 Vac input applications.

Internal voltage sensing and load side sensingInternal voltage sensors, located on the source side of the recloser, and load side voltage sensors (located on the load side of the recloser), indicate voltage magnitude within an accuracy 2% or better and a phase degree accuracy within 1.5 degrees (includes sensor, cable, and control).

Refer to Service Information MN280087EN NOVA NX-T Recloser Installation and Operation Instructions.



Radio mounting accessoryThe radio mounting accessory is powered from a voltage regulated power supply factory-calibrated with an output of 13.5 Vdc.

The output is 13.5 Vdc between TB9 pin 4 (+) and pin 5 (–) on the power supply. The output is rated for maximum continuous output of 17.25 W at 13.5 Vdc.

ote: N This output cannot be field-calibrated.

The radio will continue to operate during the loss of AC power if power is supplied from the battery. The power supply is designed to provide up to 75 Watts (peak). Refer to Table 7 for list of communications hardware accessories that can be ordered with the Form 7 control.

Contact your Eaton representative for any additional voltage requirements.

The control CPU board provides one standard 9-pin RS-232 port, one RJ45 port, two USB host ports, one USB device port, and a standard IRIG B port for user time syncing. See Figure 7.
