1.2 UR OVERVIEW 1 GETTING STARTED

1.2UR OVERVIEW 1.2.1 INTRODUCTION TO THE UR

Historically, substation protection, control, and metering functions were performed with electromechanical e quipment. This first generation of equipment was gradually replaced by analog electronic equipment, most of which emulated the singlefunction approach of their electromechanical precursors. Both of th ese technologi es required expensive cabling a nd auxiliary equipment to produce functioning systems.

Recently, digital electronic equipment has begun to provide protectio n, control, and metering functions. Initially, this equipment was either single function or had very limited multi-function capability, and did not significantly reduce the cabling and auxiliary equipment required. However, recent digital relays have become quite multi-functional, reducing cabling and auxiliaries significantly. These devices also transfer data to central control facilities and Human Machine Interfaces using electronic communications. The functions performed by these pro ducts have become so broad that many users now prefer the term IED (Intelligent Electronic Device).

It is obvious to station designers that the amount of cabling and auxiliary equipment installed in stations can be even further reduced, to 20% to 70% of the levels common in 1990, to achieve large cost r eductions. This requires placing eve n more functions within the IEDs.

Users of power equipment are also interested in reducing cost by improving power quality and pe rsonnel productivity, and as always, in increasing system reliability and efficiency. These objectives are realized through software which is used to perform functions at both the station and supervisory levels. The use of these systems is growing rapidly.

High speed communications are required to meet the data tr ansfer rates required by moder n automatic control and monitoring systems. In the near future, very high speed communications will be required to perform protection signaling with a performance target response time for a command signal between two IEDs, from transmission to reception, of less than 3 milliseconds. This has been established by the IEC 61850 standard.

IEDs with the capabilities outlined above will also provide significantly more power system data than is presently available, enhance operations and maintenance, and permit the use of adaptive system configuration for protection and control systems. This new generation of equipment must also be easily incorporated into automation systems, at both the station and enterprise levels. The GE Multilin Universal Relay (UR) has been developed to meet these goals.

1.2.2 HARDWARE ARCHITECTURE

a) UR BASIC DESIGN

The UR is a digital-based device containing a central processing unit (CPU) that handles multiple types of input and output signals. The UR can communicate over a local area network (LAN ) with an operator interface, a programming device, or another UR device.

Figure 1–2: UR CONCEPT BLOCK DIAGRAM

The CPU module contains firmware that provides protection elements in the form of logic algorithms, as well a s programmable logic gates, timers, and latches for control features.

Input elements accept a variety of analog or digital signals from the field. The UR isolates an d converts these signals into logic signals used by the relay.

Output elements convert and isolate the logic signals generated by the relay into digital or analog signals that can be used to control field devices.

b) UR SIGNAL TYPES

The contact inpu t s and output s are digital signals associated with connections to hard-wired contacts. Both ‘wet’ and ‘dry’ contacts are supported.

The vi rtual inputs and outputs are digital signals associated with UR-series internal logic signals. Virtual inputs include signals generated by the local user interface. The virtual outputs are outputs of FlexLogic™ equation s used to customize the device. Virtual outputs can also serve as virtual inputs to FlexLogic™ equations.

The analog inputs and outputs are signals that are associated with transducers, such as Resistance Temperature Detec- tors (RTDs).

The CT and VT inputs refer to analog current transformer and voltage transformer signals used to monitor AC power lines. The UR-series relays support 1 A and 5 A CTs.

The remote inputs and outputs provide a means of sharing digi tal point state information between remote UR-series devices. The remote outputs interface to the remote inputs of other UR-series devices. Remote outputs are FlexLogic™ operands inserted into IEC 61850 GSSE and GOOSE messages.

The direct inputs and outputs provide a means of sharing digital point states between a number of UR-series IEDs over a dedicated fiber (single or multimode), RS422, or G.703 interface. No switching equipment is required as the IEDs are connected directly in a ring or redundant (dual) ring configuration. This featu re is optimized for speed and intended for pilotaided schemes, distributed logic applications, or the extension of the input/output capabilities of a single relay chassis.

c) UR SCAN OPERATION

The UR-series devices operate in a cyclic scan fashion. The dev ice reads the inputs into an input status table, solves the

logic program (FlexLogic™ equation), and then sets each output to the appropriate state in an output status table. Any resulting task execution is priority interrupt-driven.

Figure 1–3: UR-SERIES SCAN OPERATION

1.2.3 SOFTWARE ARCHITECTURE

The firmware (software embedded in the relay) is designed in functional modules wh ich can be installed in any relay as required. This is achieved with object-oriented design and programming (OOD/OOP) techniques.

Object-oriented techniques involve the use of objects and classes. An object is defined as “a logical entity that contains both data and code that manipulates that data”. A class is the generalized form of similar objects. By using this concept, one can create a protection class with the protection elements as objects of the class, such as time overcurrent, instantaneous overcurrent, current differential, undervoltage, overvoltage, underfrequency, and distance. These objects represent completely self-contained software modules. The same object-class concept can be used for metering, input/output control, hmi, communications, or any functional entity in the system.

Employing OOD/OOP in the software architecture of the C70 achieves the same features as th e hardware architecture: modularity, scalability, and flexibility. The application software for any UR-series device (for example, feeder protection, transformer protection, distance protection) is constructed by co mb in i ng o b j ects from the various functionality classes. Th i s results in a common look and feel across the entire family of UR-series platform-based applications.

1.2.4 IMPORTANT CONCEPTS

As described above, the architecture of the UR-series relays differ from previous devices. To achieve a general understanding of this device, some sections of Chapter 5 are quite helpful. The most important functions of the relay are contained in “elements”. A description of the UR-series elements can be found in the Introduction to elements section in chapter 5. Examples of simple elements, and some of the organization of this manual, can be found in the Control elements section of chapter 5. An explanation of the use of inputs from CT s and VTs is in the Introduction to AC sources section in chapter 5. A description of how digital signals are used and routed within the relay is contained in the Introduction to FlexLogic™ section in chapter 5.

1.5.7 COMMISSIONING

The C70 requires a minimum amount of maintenance when it is commissioned into service. Since the C70 is a microprocessor-based relay, its characteristics do not change over time. As such, no further functional tests are required.

Furthermore, the C70 performs a number of continual self-tests and takes the necessary action in case of any major errors (see the Relay Self-tests section in chapter 7 for details). However, it is recommended that C70 maintenance be scheduled with other system maintenance. This maintenance may involve the in-service, out-of-service, or unscheduled maintenance.

In-service maintenance:

1. Visual verification of the analog values integrity such as voltage and current (in comparison to other devices on the cor-

responding system).

2. Visual verification of active alarms, relay display messages, and LED indications.

3. LED test.

4. Visual inspection for any damage, corrosion, dust, or loose wires.

5. Event recorder file download with further events analysis. Out-of-service maintenance:

1. Check wiring connections for firmness.

2. Analog values (currents, voltages, RTDs, analog inputs) injection test and metering accuracy verification. Calibrated

test equipment is required.

3. Protection elements setting verification (analog values injection or visual verification of setting file entries against relay

settings schedule).

4. Contact inputs and outputs verification. This test can be conducted by direct change of state forcing or as part of the

system functional testing.

5. Visual inspection for any damage, corrosion, or dust.

6. Event recorder file download with further events analysis.

7. LED Test and pushbutton continuity check. Unscheduled maintenance such as during a disturbance causing system interruption:

1. View the event recorder and oscillography or fault report for correct operation of inputs, outputs, and elements. If it is concluded that the relay or one of its modules is of concern, contact GE Multilin for prompt service.

2 PRODUCT DESCRIPTION 2.1 INTRODUCTION

2 PRODUCT DESCRIPTION 2.1INTRODUCTION 2.1.1 OVERVIEW

The C70 Capacitor Bank Protection and Control System is a UR-series microprocessor-based relay for protection and control of small, medium, and large three-phase capacitor banks. The relay can be ordered with up to three CT/VT modules, allowing for flexible application to variety of bank configurations.

The key protection functions are designed to cover grounded and ungrounded, single and parallel banks. Sensitive protection functions support compensation for both external (system) unbalance and inherent unba lance of the capacitor bank itself. Both voltage and current-based balance protection functions are available. Algorithms are developed to automatically select compensation settings after repairs or other alternations of the bank.

The relay supports variety of bank configurations through flexible configurations of its AC inputs, installed voltage and current transformers, and resulting protection techniques.

The relay incorporates an automatic voltage regulator (AVR) responding to either voltage, reactive power, or power factor. A separate timer function initiates controls on a pre-defined time /date basis. These on-off type controls are meant to automatically close or open the associated breaker. A supervisory function is provided to program the local/remote, auto/manual functionality, temporary inhibit closing after tripping, and other auxiliary functions such as operation counters.

A capacitor control element provides remote/local and auto/manual control regulation, trip/close interlocking, and seal-in. A user-programmable time delay inhibits closing until after the bank discharges itself to a safe level.

Up to six contact input/output modules can be ordered. The relay can also equipped with a serial 64/128 kbps direct input/ output module for fast and reliable peer-to-peer communication with other UR-series IEDs.

The C70 metering functions include true RMS and phasors for currents and voltages, current and voltage harmonics and THD, symmetrical components, frequency, power, power factor.

Diagnostic features include an event recorder capable of storing 1024 time-tagged events, oscillography capable of storing up to 64 records with programmable trigger, content and sampling rate, and data logger acquisition of up to 16 channels, with programmable content and sampling rate. The internal clock us ed for time-tagging can be synch ronized with an IRIGB signal or via the SNTP protocol over the Ethernet port. This preci se time stamping allows the sequence o f events to be determined throughout the system. Events can also be programmed (via FlexLogic™) to trigger oscillography data capture which may be set to record the measured parameters before and after the event for viewing on a personal computer. These tools significantly reduce troubleshooting time and simplify report generation in the event of a system fault.

A faceplate RS232 port may be used to connect to a PC for the programming of settings and the monitoring of actual values. A variety of communications modules are available. Two rear RS485 ports allow independent access by operating and engineering staff. All serial ports use the Modbus with baud rates up to 115.2 kbps. The RS232 port has a fixed baud rate of 19.2 kbps. Optional communications modules include a 10/100Base-T or 10Base-F Ethernet interface which can b e used to provide fast, reliable communications in noisy environments. Another option provides two 10BaseF fiber optic ports for redundancy . The Ethernet port supports IEC 61850, Modbus The IEC 60870-5-104 protocol is supported on the Ethernet port. DNP 3.0 and IEC 6087 0-5-104 cann ot be enabled at the same time.

The C70 IEDs use flash memory technology which allows field upgradi ng as new fea tures are added. The follow ing single line diagram illustrates the relay functionality using ANSI (American National Standards Institute) device numbers.

ETHERNET SWITCH FIBER OPTIC PORTS

Maximum fiber segment length calculation: The maximum fiber segment length between two adjacent

switches or between a switch and a device is calculated as follows. First, calculate the optical power budget (OPB) of each device using the manufacturer’s data sheets.

where OPB = optical power budget, P

= receiver sensitivity.

and P

The worst case optical power budget (OPB lated by taking the lower of the two calculated power budgets, subtracting 1 dB for LED aging, and then subtracting the total insertion loss. The total insertion loss is calculated by multiplying the number of connectors in each single fiber path by 0.5 dB. For example, with a single fiber cable between the two devices, there will be a minimum of two connections in either transmit or receive fiber paths for a total insertion loss of 1db for either direction:

The worst-case optical power budget between two type 2T or 2S modules using a single fiber cable is:

To calculate the maximum fiber length, divide the worst-case optical power budget by the cable attenuation per unit distance specified in the manufacturer data sheets. For example, typical attenuation for 62.5/125 μm glass fiber optic cable is approximately 2.8 dB per km. In our example, this would result in the following maximum fiber length:

a) HORIZONTAL UNITS

The C70 Capacitor Bank Protection and Control System is available as a 19-i nch rack hori zontal mount unit with a removable faceplate. The faceplate can be specified as either standard or enhanced at the time of ord ering . The e nhanced faceplate contains additional user-programmable pushbuttons and LED indicators.

The modular design allows the relay to be easily upgraded or repaired by a qualified service person . The faceplate is hinged to allow easy access to the removable modules, and is itself removable to allow mounting on doors with limited rear depth. There is also a removable dust cover that fits over the faceplate, which must be removed when attempting to access the keypad or RS232 communications port.

The case dimensions are shown below, along with panel cutout details for panel mounting. When planning the location of your panel cutout, ensure that provision is made for the faceplate to swing open without interference to or from adjacent equipment.

The relay must be mounted such that the faceplate sits semi-flush with the panel or switchgear door, allowing the operator access to the keypad and the RS232 communications port. The relay is secured to the panel with the use of four screws supplied with the relay.

3.1.2 MODULE WITHDRAWAL AND INSERTION

Module withdrawal and insertion may only be performed when control power has been removed from the unit. Inserting an incorrect module type into a slot may result in personal injury, damage to the unit or connected equipment, or undesired operation!

Proper electrostatic discharge protection (for example, a static strap) must be used when coming in contact with modules while the relay is energized!

The relay, being modular in design, allows for the withdrawal and insertion of modules. Modules must only be replaced with like modules in their original factory configured slots.

The enhanced faceplate can be opened to the left, once the thumb screw has been removed, as sho wn below. This allows for easy accessibility of the modules for withdrawal. The new wide-angle hinge assembly in the enhanced front panel opens completely and allows easy access to all modules in the C70.

The standard faceplate can be opened to the left, once the sliding latch on the right side has been pushed up, as shown below. This allows for easy accessibility of the modules for withdrawal.

Figure 3–9: UR MODULE WITHDRAWAL AND INSERTION (STANDARD FACEPLATE)

To properly remove a module, the ejector/inserter clips, located at the top and bottom of each module, must be pull ed simultaneously. Before performing this action, control power must be removed from the relay. Record the original location of the module to ensure that the same or replacement module is inserted into the correct slot. Modules with current input provide automatic shorting of external CT circuits.

To properly insert a module, ensure that the correct module typ e is inserted into the correct slot position. The ejector/ inserter clips located at the top and at the bottom of each module must be in the disengaged position as the modu le is smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips simultaneously. When the clips have locked into position, the module will be fully inserted.

All CPU modules except the 9E are equipped with 10/100Base-T or 100Base-F Etherne t connectors. These connectors must be individually disconnected from the module before it can be removed from the chassis.

3.1.3 REAR TERMINAL LAYOUT

Do not touch any rear terminals while the relay is energized!

The relay follows a convention with respect to terminal number assign ments which are three characters long assigned in order by module slot position, row number, and column letter. Two-slot wide modules take their slot designation from the first slot position (nearest to CPU module) which is indicated by an arrow marker on the terminal block. See the following figure for an example of rear terminal assignments.

Filter networks and transient protection clamps are used in the hardware to prevent damage caused b y high peak voltage transients, radio frequency interference (RFI), and electromagnetic i nterference (EMI). These protective components can be damaged by application of the ANSI/IEEE C37.90 specified test voltage for a period longer than the specified one minute.

3.2.3 CONTROL POWER

CONTROL POWER SUPPLIED TO THE RELAY MUST BE CONNECTED TO THE MA TCHING POWER SUPPLY RANGE OF THE RELAY. IF THE VOLTAGE IS APPLIED TO THE WRONG TERMINALS, DAMAGE MAY OCCUR!

The C70 relay, like almost all electronic relays, contains electrolytic capacitors. These capacitors are well known to be subject to deterioration over ti me if voltage is not applied periodically. Deterioration can be avoided by powering the relays up once a year.

The power supply module can be ordered for two possible voltage ranges, wi th or without a re dundant po wer op tion. Each range has a dedicated input connection for proper operation. The ranges are as shown below (see the Technical specifica- tions section of chapter 2 for additional details):

• Low (LO) range: 24 to 48 V (DC only) nominal.

• High (HI) range: 125 to 250 V nominal. The power supply module provides power to the relay and supplies power for dry contact input connections. The power supply module provides 48 V DC power for dry contact input connections and a critical failure relay (see the

Typical wiring diagram earlier). The critical failure relay is a form-C devic e that will be energized once control power is applied and the relay has successfully booted up with no critical self-test failu res. If on-going self-test diagnostic checks detect a critical failure (see the Self-test errors section in chapter 7) or control power is lost, the relay will de-energize.

For high reliability systems, the C70 has a redundant option in which two C70 power supplies are pla ced in parallel on the bus. If one of the power supplies become faulted, the second power supply will assume the full load of the relay without any interruptions. Each power supply has a green LED on the front of the module to indicate it is functional. The critical fail relay of the module will also indicate a faulted power supply.

3.2.4 CT/VT MODULES

A CT/VT module may have voltage inputs on channels 1 through 4 inclusive, or channels 5 through 8 inclusive. Channels 1 and 5 are intended for connection to phase A, and are labeled as such in the relay. Likewise, channels 2 and 6 are intended for connection to phase B, and channels 3 and 7 are intended for connection to phase C.

Channels 4 and 8 are intended for connection to a single-phase source. For voltage inputs, these channel are labelled as auxiliary voltage (VX). For current inputs, these channels are intended for connection to a CT between system neu tral and ground, and are labelled as ground current (IG).

Verify that the connection made to the relay nominal current of 1 A or 5 A matches the secon dar y r ating of the connected CTs. Unmatched CTs may result in equipment damage or inadequate protection.

CT/VT modules may be ordered with a standard ground current input that is the same as the phase current input. Each AC current input has an isolating transformer and an automatic shorting me chanism that shorts the input when the mo dule is withdrawn from the chassis. There are no internal ground connections on the current inputs. Current transformers with 1 to 50000 A primaries and 1 A or 5 A secondaries may be used.

The above modules are available with enhanced diagnostics. These modules can automatically detect CT/VT hardware failure and take the relay out of service.

CT connections for both ABC and ACB phase rotations are identical as shown in the Typical wiring diagram. The exact placement of a zero-sequence core balance CT to detect ground fault current is shown below. Twisted-pair

cabling on the zero-sequence CT is recommended.

3.2.5 PROCESS BUS MODULES

The C70 can be ordered with a process b us interface module. This module is designed to interface with the GE Multilin HardFiber system, allowing bi-directional IEC 61850 fiber optic communications with up to eight HardFiber merging units, known as Bricks. The HardFiber system has been designed to integrate seamlessly with the existing UR-series applications, including protection functions, FlexLogic™, metering, and communications.

The IEC 61850 process bus system offers the following benefits.

• Drastically reduces labor associated with design, installation, and testing of protecti on and control applications using the C70 by reducing the number of individual copper terminations.

• Integrates seamlessly with existing C70 applications, since the IEC 61850 process bus interface module replaces the traditional CT/VT modules.

• Communicates using open standard IEC 61850 messaging.

For additional details on the HardFiber system, refer to GE publication GEK-113500: HardFiber System Instruction Manual.

3.2.6 CONTACT INPUTS AND OUTPUTS

Every contact input/output module has 24 terminal connections. They a re arranged as three terminals per row, with eight rows in total. A given row of three terminals may be used for the outputs of one relay. For example, for form-C relay outputs, the terminals connect to the normally open (NO), normally closed (NC), and common contacts of the relay. For a form-A output, there are options of using current or voltage detection for feature supervision, depending on the modu le ordered. The terminal configuration for contact inputs is different for the two applications.

The contact inputs are grouped with a common return. The C70 has two versions of grouping: four inputs per common return and two inputs per common return. When a contact input/output module is ordered, four inputs per common is used. The four inputs per common allows for high-density inputs in combination with outputs, with a compromise of four inputs sharing one common. If the inputs must be isolated per row, then two inputs per common return should be selected (4D module).

The tables and diagrams on the following pages illustrate the module type s (6A, etc.) and contact arrangements that may be ordered for the relay. Since an entire row is used for a single contact output, the name is assigned using the module slot position and row number. However, since there are two contact inputs per row, these names are assigned by module slot position, row number, and column position.

Some form-A / solid-state relay outputs include circuits to monitor the DC voltage across the output contact when it is open, and the DC current through the output contact when it is closed. Each of the monitors contains a level detector wh ose ou tput is set to logic “On = 1” when the current in the circuit is above the threshold setting. The voltage monitor is set to “On = 1” when the current is above about 1 to 2.5 mA, and the current monitor is set to “On = 1” when the current exceeds about 80 to 100 mA. The voltage monitor is intended to check the health of the overall trip circuit, and th e current monitor can be used to seal-in the output contact until an external contact has interrupted current flow.

Block diagrams are shown below for form-A and solid-state relay outputs with optional voltage monitor, optional current monitor, and with no monitoring. The actual values shown for contact output 1 are the same for all contact outputs.

Figure 3–16: FORM-A AND SOLID-STATE CONTACT OUTPUTS WITH VOLTAGE AND CURRENT MONITORING

The operation of voltage and current monitors is reflected with the co rresponding FlexLo gic™ operands (CONT OP # VON,

CONT OP # VOFF, and CONT OP # ION) which can be used in protection, control, and alarm logic. The typical appl ication of

the voltage monitor is breaker trip circuit integrity monitoring; a typical application of the curren t monitor is seal-in of the control command.

Refer to the Digital elements section of chapter 5 for an example of how form-A and solid-state relay contacts can be applied for breaker trip circuit integrity monitoring.

Relay contacts must be considered unsafe to touch when the unit is energized! If the relay contacts need to be used for low voltage accessible applications, it is the customer’s responsibility to ensure proper insulation levels!

USE OF FORM-A AND SOLID-STATE RELAY OUTPUTS IN HIGH IMPEDANCE CIRCUITS

For form-A and solid-state relay output contacts internally equipped with a voltage measuring cIrcuit across the contact, the circuit has an impedance that can cause a problem when used in conjunction with external high input impedance monitoring equipment such as modern relay test set trigger circuits. These monitoring circuits may continue to read the form-A contact as being closed after it has closed and subsequently opened, w hen measured as an impedance.

The solution to this problem is to use the voltage measuring trigger input of the relay test set, and connect the formA contact through a voltage-dropping resistor to a DC voltage source. If the 48 V DC output of the power supply is used as a source, a 500 Ω, 10 W resisto r is appropriate. In this configuration , the voltage across either the fo rm-A contact or the resistor can be used to monitor the state of the output.

Wherever a tilde “~” symbol appears, substitute with the slot position of the mo dule; wherever a number sign “#” appears, substitute the contact number

When current monitoring is used to seal-in the form-A and solid-state relay contact outputs, the FlexLogic™ operand driving the contact output should be given a reset delay o f 10 ms to prevent damage of the output contact (in situations when the element initiating the contact output is bouncing, at values in the region of the pickup value).

CONTACT INPUTS:

A dry contact has one side connected to terminal B3b. This is the positive 48 V DC voltage rail supplied by the p ower supply module. The other side of the dry contact is connected to the required contact input terminal. Each contact input group has its own common (negative) terminal which must be connected to the DC negative terminal (B3a) of the power supply module. When a dry contact closes, a current of 1 to 3 mA will flow through the associated circuit.

A wet contact has one side connected to the positive terminal of an external DC power supply. The other side of this contact is connected to the required contact input terminal. If a wet contact is used, then the negative side of the external source must be connected to the relay common (negative) terminal of each contact group. The maximu m external source voltage for this arrangement is 300 V DC.

The voltage threshold at which each group of four contact inputs will detect a closed contact input is programmable as 17 V DC for 24 V sources, 33 V DC for 48 V sources, 84 V DC for 110 to 125 V sources, and 166 V DC for 250 V sources.

Figure 3–19: DRY AND WET CONTACT INPUT CONNECTIONS

Wherever a tilde “~” symbol appears, substitute with the slot position of the module.

Contact outputs may be ordered as form-a or form-C. The form-A contacts may be connected for external circuit supervision. These contacts are provided with voltage and current monitoring circuits used to detect the loss of DC voltage in the circuit, and the presence of DC current flowing through the contacts when the form-A contact closes. If enabled, the current monitoring can be used as a seal-in signal to ensure that the form-A contact does not attempt to break the energized inductive coil circuit and weld the output contacts.

There is no provision in the relay to detect a DC ground fau lt on 48 V DC control power external output. We recommend using an external DC supply.

USE OF CONTACT INPUTS WITH AUTO-BURNISHING:

The contact inputs sense a change of the state of the external device contact based on the measured current. When external devices are located in a harsh industrial environment (either outdoor or indoor), their contacts can be exposed to various types of contamination. Normally, there is a thin film of insulating sulfidation, oxidation, or contaminates on the surface of the contacts, sometimes making it difficult or impossible to detect a change of the state. This film must be removed to establish circuit continuity – an impulse of higher than normal current can accomplish this.

The contact inputs with auto-burnish create a high current impulse when the threshold is reached to burn off this oxidation layer as a maintenance to the contacts. Afterwards the contact input current is reduced to a steady-state current. The impulse will have a 5 second delay after a contact input changes state.

Figure 3–20: CURRENT THROUGH CONTACT INPUTS WITH AUTO-BURNISHING

Regular contact inputs limit current to less than 3 mA to reduce station battery burden. In contrast, contact inputs with autoburnishing allow currents up to 50 to 70 mA at the first instance when the change of state was sensed. Then, within 25 to 50 ms, this current is slowly reduced to 3 mA as indicated above. The 50 to 70 mA peak current burns any film on the contacts, allowing for proper sensing of state changes. If the external device contact is bouncing, the auto-burnishing starts when external device contact bouncing is over.

Another important difference between the auto-burnishing input module and the regular input modules is that only two contact inputs have common ground, as opposed to four contact inputs sharing one common ground (refer to the Contact Input and Output Module Wiring diagrams). This is beneficial when connecting contact inputs to separate voltage sources. Consequently, the threshold voltage setting is also defined per group of two contact inputs.

The auto-burnish feature can be disabled or enabled using the DIP switches foun d on each daughter card. Th ere is a DIP switch for each contact, for a total of 16 inputs.

Figure 3–21: AUTO-BURNISH DIP SWITCHES

The auto-burnish circuitry has an internal fuse for safety purposes. During regula r maintenance, the auto-burnish functionality can be checked using an oscilloscope.

3.2.7 TRANSDUCER INPUTS/OUTPUTS

Transducer input modules can receive input signals from external dcmA output transducers (dcmA In) or resistance temperature detectors (RTD). Hardware and software is provided to receive signals from these external transducers and convert these signals into a digital format for use as required.

Transducer output modules provide DC current outputs in several standard dcmA ranges. Software is provided to configure virtually any analog quantity used in the relay to drive the analog outputs.

Every transducer input/output module has a total of 24 terminal connections. These connections are arranged as three terminals per row with a total of eight rows. A given row may be used for either inputs or outputs, with terminals in column "a" having positive polarity and terminals in column "c" having negati ve polarity. Since an entire row is used for a single input/ output channel, the name of the channel is assigned using the module slot position and row number.

Each module also requires that a connection from an exte rnal ground bus be made to terminal 8b. The current outputs require a twisted-pair shielded cable, where the shield is grounded a t one end only. The figure below illustrates the transducer module types (5A, 5C, 5D, 5E, and 5F) and channel arrangements that may be ordered for the relay.

Wherever a tilde “~” symbol appears, substitute with the slot position of the module.

b) RS485 PORTS

RS485 data transmission and reception are accomplished over a single twisted pair with transmit and receive data alternating over the same two wires. Through the use of these ports, continuous mo nitoring and control from a remote comp uter, SCADA system or PLC is possible.

To minimize errors from noise, the use of shielded twisted pair wire is recommended. Correct polarity must also be observed. For instance, the relays must be connected with all RS485 “+” terminals connected togeth er, and all RS485 “–” terminals connected together. The COM terminal should be connected to the common wire inside th e shield, when provided. To avoid loop currents, the shield should be grounded at one point only. Each relay should also be daisy chained to the next one in the link. A maximum of 32 relays can be connected in this manner without exceeding driver capability. For larger systems, additional serial channels must be added. It is also possible to use commercially available repeaters to increase the number of relays on a single channel to more than 32. Star or stub connections should be avoided entirely.

Lightning strikes and ground surge currents can cause large mo mentary voltage differences between remote ends of the communication link. For this reason, surge protection devices are internally provided at both communi cation ports. An iso-

lated power supply with an optocoupled data interface also acts to reduce noise coupling. To ensure maximum reliability, all equipment should have similar transient protection devices installed.

Both ends of the RS485 circuit should also be terminated with an impedance as shown below.

ENSURE THE DUST COVERS ARE INSTALLED WHEN THE FIBER IS NOT IN USE. DIRTY OR SCRATCHED CONNECTORS CAN LEAD TO HIGH LOSSES ON A FIBER LINK.

OBSERVING ANY FIBER TRANSMITTER OUTPUT MAY CAUSE INJURY TO THE EYE.

The fiber optic communication ports allow for fast and efficient communications between relays at 10 Mbps or 100 Mbps. Optical fiber may be connected to the relay supporting a wa velength of 820 nm in multi-mode or 1310 nm in multi-mode and single-mode. The 10 Mbps rate is available for CPU modules 9G and 9H; 100Mbps is available for modules 9H, 9J, 9K, 9L, 9M, 9N, 9P, and 9R. The 9H, 9K, 9M, and 9R modules have a second pair of identical optical fiber transmitter and receiver for redundancy.

The optical fiber sizes supported include 50/125 µm, 62.5/125 µm and 100/140 µm for 10 Mbps. The fiber optic port is designed such that the response times will not vary for any core that is 100 µm or less i n diameter, 62.5 µm for 100 Mbps. For optical power budgeting, splices are required every 1 km for the transmitter/receiver pair. When splicing optical fibers, the diameter and numerical aperture of each fiber must be the same. In order to engage or disengage the ST type connector, only a quarter turn of the coupling is required.

3.3DIRECT INPUT/OUTPUT COMMUNICATIONS 3.3.1 DESCRIPTION

The C70 direct inputs and outputs feature makes use of the type 7 series of communication s modules. These modules are also used by the L90 Line Differential Relay for inter-relay communications. The direct input and output feature uses the communications channels provided by these modules to exchange digital state information between relays. This feature is available on all UR-series relay models except for the L90 Line Differential relay.

The communications channels are normally connected in a ring configuration as shown below. The transmitter of one module is connected to the receiver of the next module. The transmitter of this second module is then connected to the receiver of the next module in the ring. This is continued to form a communication s ring. The figure below illustrates a ring of four UR-series relays with the following connections: UR1-Tx to UR2-Rx, UR2-Tx to UR3-Rx, UR3-Tx to UR4-Rx, and UR 4-Tx to UR1-Rx. A maximum of sixteen (16) UR-series relays can be connected in a single ring

Figure 3–28: DIRECT INPUT AND OUTPUT SINGLE CHANNEL CONNECTION

The interconnection for dual-channel Type 7 communications modules is shown be low. Two channel modules allow for a redundant ring configuration. That is, two rings can be created to provide an additional independent data path. The required connections are: UR1-Tx1 to UR2-Rx1, UR2-Tx1 to UR3-Rx1, UR3-Tx1 to UR4-Rx1, and UR4-Tx1 to UR1-Rx1 for the first ring; and UR1-Tx2 to UR4-Rx2, UR4-Tx2 to UR3-Rx2, UR3-Tx2 to UR2-Rx2, and UR2-Tx2 to UR1-Rx2 for the second ring.

The following diagram shows the connection for three UR-se ries relays using two indepe ndent communication channels. UR1 and UR3 have single type 7 communication modules; UR2 has a dual-channel module. The two communication channels can be of different types, depending on the Type 7 modules used. To allow the direct input and output data to cross- over from channel 1 to channel 2 on UR2, the forces UR2 to forward messages received on Rx1 out Tx2, and messages received on Rx2 out Tx1.

3.3.3 G.703 INTERFACE

a) DESCRIPTION

The following figure shows the 64K ITU G.703 co-directional interface configuration.

The G.703 module is fixed at 64 kbps. The

SETTINGS Ö PRODUCT SETUP ÖØ DIRECT I/O ÖØ DIRECT I/O DATA RATE

setting is not applicable to this module.

AWG 24 twisted shielded pair is recommended for external connections, with the shield grounded only at one end. Connecting the shield to pin X1a or X6a grounds the shield since these pins are internally connected to ground. Thus, if pin X1a or X6a is used, do not ground at the other end. This interface module is protected by surge suppression devices.

Figure 3–32: G.703 INTERFACE CONFIGURATION

The following figure shows the typical pin interconnectio n between two G.703 interfaces. For the actual physical arrangement of these pins, see the Rear terminal assignments section earlier in this chapter. All pin interconnections are to be maintained for a connection to a multiplexer.

Figure 3–33: TYPICAL PIN INTERCONNECTION BETWEEN TWO G.703 INTERFACES

Pin nomenclature may differ from one manufacturer to another. Therefore, it is not uncommon to see pinouts numbered TxA, TxB, RxA and RxB. In such cases, it can be assumed that “A” is equivalent to “+” and “B” is equivalent to “–”.

b) G.703 SELECTION SWITCH PROCEDURES

1. Remove the G.703 module (7R or 7S). The ejector/i nserter clips located at th e top and at the bottom of each module, must be pulled simultaneously in order to release the module for removal. Before performing this action, control power must be removed from the relay. The original location of the module should be recorded to help ensure that the same or replacement module is inserted into the correct slot.

2. Remove the module cover screw.

3. Remove the top cover by sliding it towards the rear and then lift it upwards.

4. Set the timing selection switches (channel 1, channel 2) to the desired timing modes.

5. Replace the top cover and the cover screw.

3-30 C70 Capacitor Bank Protection and Control System GE Multilin

3 HARDWARE 3.3 DIRECT INPUT/OUTPUT COMMUNICATIONS

6. Re-insert the G.703 module. Take care to ensure that the correct module type is inserted into the correct slot position.

The ejector/inserter clips located at the top and at the bottom of each modu le must be in the disengaged position as the module is smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips simultaneously. When the clips have locked into position, the module will be fully inserted.

Table 3–5: G.703 TIMING SELECTIONS

SWITCHES FUNCTION

S1 OFF → octet timing disabled

S5 and S6 S5 = OFF and S6 = OFF → loop timing mode

c) G.703 OCTET TIMING

If octet timing is enabled (on), this 8 kHz signal will be asserted during the violation of bit 8 (L SB) necessary for connecting to higher order systems. When C70s are connected back to back, octet timing should be disabled (off).

d) G.703 TIMING MODES

There are two timing modes for the G.703 module: internal timing mode and loop timing mode (default).

• Internal Timing Mode: The system clock is generated internally. Therefore, the G.703 timing selection should be in

the internal timing mode for back-to-back (UR-to-UR) conn ections. For back-to-back connections, set for octet timing (S1 = OFF) and timing mode to internal timing (S5 = ON and S6 = OFF).

• Loop Timing Mode: The system clock is derived from the received line signal . Therefore, the G.703 timing selection

should be in loop timing mode for connections to higher order systems. For connection to a higher order system (URto-multiplexer, factory defaults), set to octet timing (S1 = ON) and set timing mode to loop timing (S5 = OFF and S6 = OFF).

ON → octet timing 8 kHz

S5 = ON and S6 = OFF → internal timing mode S5 = OFF and S6 = ON → minimum remote loopback mode S5 = ON and S6 = ON → dual loopback mode

e) G.703 TEST MODES

In minimum remote loopback mode, the multiplexer is enabled to return the data from the external interface without any

processing to assist in diagnosing G.703 line-side problems irrespective of clock rate. Data enters from the G.703 inputs, passes through the data stabilization latch which also restores the proper signal polarity, passes through the multiplexer and then returns to the transmitter. The differential received data is processed and passed to the G.703 transmitter module after which point the data is discarded. The G.703 receiver module is fully functional and continues to process data and passes it to the differential Manchester transmitter module. Since timing is returned as it is received, the timing sour ce is expected to be from the G.703 line side of the interface.

Figure 3–35: G.703 MINIMUM REMOTE LOOPBACK MODE

In dual loopback mode, the multiplexers are active and the function s of the circuit are divide d into two with each receiver/ transmitter pair linked together to deconstruct and then reconstruct their respective signals. Differential Manchester data enters the Differential Manchester receiver module and then is returned to the differential Manchester transmitter module. Likewise, G.703 data enters the G.703 receiver module and is passed through to the G.703 transmitter module to be returned as G.703 data. Because of the complete split in the communicatio ns path and because, in each case, the clocks are extracted and reconstructed with the outgoing data, in this mode there must be two independent sources of timing. One source lies on the G.703 line side of the interface while the other lies on the differential Manchester side of the interface.

3.3.4 RS422 INTERFACE

a) DESCRIPTION

There are two RS422 inter-relay communications modules avai lab le: singl e-channel RS4 22 (modu le 7T) and dual -chann el RS422 (module 7W). The modules can be configured to run at 64 kbps or 128 kbps. AWG 24 twisted shielded pair cable is recommended for external connections. These modules are protected by optically-isolated surge suppression devices.

The shield pins (6a and 7b) are internally connected to the ground pin (8a). Proper shield termination is as follows:

• Site 1: Terminate shield to pins 6a or 7b or both.

• Site 2: Terminate shield to COM pin 2b. The clock terminating impedance should match the impedance of the line.

The following figure shows the typical pin interconnection between two single-channel RS422 interfaces installed in slot W. All pin interconnections are to be maintained for a connection to a multiplexer.

b) TWO-CHANNEL APPLICATION VIA MULTIPLEXERS

The RS422 interface may be used for single channel or two channel applic ations over SONET/SDH or multiplexed systems. When used in single-channel applications, the RS422 interface links to highe r order systems in a typical fashion observing transmit (Tx), receive (Rx), and send timing (ST) connections. However, when used in two-channel applications, certain criteria must be followed since there is one clock input for the two RS422 channels. The system will function correctly if the following connections are observed and your data modu le has a terminal timing feature. Terminal timing is a common feature to most synchronous data units that allows the module to accept timing from an external source. Using the terminal timing feature, two channel applications can be achieved if th ese connections are followed: Th e send timing outputs from the multiplexer (data module 1), will connect to the clock inputs of the UR–RS422 interface in the u sual fashion. In addition, the send timing outputs of data module 1 will also be paralleled to the terminal timing inputs of data module 2. By using this configuration, the timing for both data modules and both UR–RS422 cha nnels will be derived from a single clock source. As a result, data sampling for both of the UR–RS422 channels will be synchronized via the send timing leads on data module 1 as shown below. If the terminal timing feature is not available or this type of connection is not desired, the G.703 interface is a viable option that does not impose timing restrictions.

Figure 3–39: TIMING CONFIGURATION FOR RS422 TWO-CHANNEL, 3-TERMINAL APPLICATION

Data module 1 provides timing to the C70 RS422 interface via the ST(A) and ST(B) outputs. Data module 1 also provides timing to data module 2 TT(A) and TT(B) inputs via the ST(A) and AT(B) outputs. The data module pin numbers have been omitted in the figure above since they may vary depending on the manufacturer.

c) TRANSMIT TIMING

The RS422 interface accepts one clock input for transmit timing. It is important that the rising edge of the 64 kHz transmit timing clock of the multiplexer interface is sampling the data in the center of the transmit data window. Therefore, it is important to confirm clock and data transitions to ensure proper system operation. For example, the followin g figure shows the positive edge of the Tx clock in the center of the Tx data bit.

d) RECEIVE TIMING

The RS422 interface utilizes NRZI-MARK modulation code and; therefore, does not rely on an Rx clock to reca pture data. NRZI-MARK is an edge-type, invertible, self-clocking code.

3-34 C70 Capacitor Bank Protection and Control System GE Multilin

Figure 3–40: CLOCK AND DATA TRANSITIONS

3 HARDWARE 3.3 DIRECT INPUT/OUTPUT COMMUNICATIONS

To recover the Rx clock from the data-stream, an integrated DPLL (digital phase lock loop) circuit is utilized. The DPLL is driven by an internal clock, which is 16-times over-sampled, and uses this clock along with the data-stream to generate a data clock that can be used as the SCC (serial communication controller) receive clock.

3.3.5 IEEE C37.94 INTERFACE

The UR-series IEEE C37.94 communication modules (modules types 2G, 2H, 76, and 77) are designed to interface with IEEE C37.94 compliant digital multiplexers or an IEEE C37.94 compliant interface converter for use with direct input and output applications for firmware revisions 3.30 and higher. The IEEE C37.94 standard defines a point-to-point optical link for synchronous data between a multiplexer and a teleprotection device. This data is typically 64 kbps, but the standard provides for speeds up to 64n kbps, where n = 1, 2,…, 12. The UR-series C37.94 communication modul es are either 64 kbps (with n fixed at 1) for 128 kbps (with n fixed at 2). The frame is a valid International Telecommunications Union (ITU-T) recommended G.704 pattern from the standpoint of framing and data rate. The frame is 256 bits and is repeated at a frame rate of 8000 Hz, with a resultant bit rate of 2048 kbps.

The specifications for the module are as follows:.

• IEEE standard: C37.94 for 1 × 128 kbps optical fiber interface (for 2G and 2H modules) or C37.94 for 2 × 64 kbps opti-

cal fiber interface (for 76 and 77 modules).

• Fiber optic cable type: 50 mm or 62.5 mm core diameter optical fiber.

• Fiber optic mode: multi-mode.

• Fiber optic cable length: up to 2 km.

• Fiber optic connector: type ST.

• Wavelength: 830 ±40 nm.

• Connection: as per all fiber optic connections, a Tx to Rx connection is required. The UR-series C37.94 communication module can be connected di rectl y to any compliant digital multiplexe r that supports

the IEEE C37.94 standard as shown below.

The UR-series C37.94 communication module can be connected to the electrical interface (G.703, RS422, or X.21) of a non-compliant digital multiplexer via an optical-to-electrical interface converter that su pports the IEEE C37.94 standard, as shown below.

GE Multilin C70 Capacitor Bank Protection and Control System 3-35

3.3 DIRECT INPUT/OUTPUT COMMUNICATIONS 3 HARDWARE

842753A1.CDR

The UR-series C37.94 communication module has six (6) switches that are used to set the clock configuration. The functions of these control switches is shown below.

For the internal timing mode, the system clock is generated internally. therefore, the timing switch selection should be internal timing for relay 1 and loop timed for relay 2. There must be only one timing source configured.

For the looped timing mode, the system clock is derived from the received line signal. Therefore, the timing selecti on should be in loop timing mode for connections to higher order systems.

The IEEE C37.94 communications module cover removal procedure is as follows:

1. Remove the IEEE C37.94 module (type 2G, 2H, 76, or 77 module): The ejector/inserter clips located at the top and at the bottom of each module, must be pul led simultaneously in order

to release the module for removal. Before performing this action, control power must be removed from the relay. The original location of the module should be recorded to help ensure that the same or replacement module is inserted into the correct slot.

2. Remove the module cover screw.

3. Remove the top cover by sliding it towards the rear and then lift it upwards.

4. Set the timing selection switches (channel 1, channel 2) to the desired timing modes (see description above).

5. Replace the top cover and the cover screw.

6. Re-insert the IEEE C37.94 module. Take care to ensure that the correct module type is inserted into the correct slot position. The ejector/inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips simultaneously. When the clips have locked into position, the module will be fully inserted.

4 HUMAN INTERFACES 4.1ENERVISTA UR SETUP INTERFACE 4.1.1 INTRODUCTION

The EnerVista UR Setup software provides a graphical user interface (GUI) as one of two human interfaces to a UR device. The alternate human interface is implemented via the device’s faceplate keypad and display (refer to the Faceplate inter- face section in this chapter).

The EnerVista UR Setup software provides a single facility to configure, monitor, maintain, and trouble-shoot the operation of relay functions, connected over local or wide area communication networks. It can be used while disconnected (off-line) or connected (on-line) to a UR device. In off-line mode, settings files can be created for eventual downloading to the device. In on-line mode, you can communicate with the device in real-time.

The EnerVista UR Setup software, provided with every C70 relay, can be run from any computer supporting Microsoft

95, 98, NT, 2000, ME, and XP. This chapter provides a summary of the basic EnerVista UR Setup software interface

dows features. The EnerVista UR Setup Help File provides details for getting started and using the EnerVista UR Setup software interface.

4.1.2 CREATING A SITE LIST

To start using the EnerVista UR Setup software, a site definition and device definition must first be created. See the EnerVista UR Setup Help File or refer to the Connecting EnerVista UR Setup with the C70 section in Cha pter 1 for details.

4.1.3 ENERVISTA UR SETUP OVERVIEW

a) ENGAGING A DEVICE

The EnerVista UR Setup software may be used in on-line mode (relay connected) to directly communicate with the C70 relay. Communicating relays are organized and grouped by communication interfaces and into sites. Sites may contain any number of relays selected from the UR-series of relays.

Win-

b) USING SETTINGS FILES

The EnerVista UR Setup software interface supports three ways of handling changes to relay settings:

• In off-line mode (relay disconnected) to create or edit relay settings files for later download to communicating relays.

• While connected to a communicating relay to directl y modify any rel ay settings via relay data view windows, and th en save the settings to the relay.

• You can create/edit settings files and then write them to the relay while the interface is connected to the relay.

Settings files are organized on the basis of file names assigned by the user. A settings file contains data pertaining to the following types of relay settings:

• Device definition

• Product setup

• System setup

• FlexLogic™

• Grouped elements

• Control elements

• Inputs/outputs

• Testing

Factory default values are supplied and can be restored after any changes. The following communications settings are not transferred to the C70 with settings files.

c) CREATING AND EDITING FLEXLOGIC™

You can create or edit a FlexLogic™ equation in order to customize the relay. You can subsequently view the automatically generated logic diagram.

d) VIEWING ACTUAL VALUES

You can view real-time relay data such as input/output status and measured parameters.

e) VIEWING TRIGGERED EVENTS

While the interface is in either on-line or off-line mode, you can view and analyze data generated by tri ggered specified parameters, via one of the following:

• Event Recorder facility: The e vent recorder captures contextual data associated with the last 1024 events, listed in chronological order from most recent to oldest.

• Oscillography facility: The oscillography waveform traces and digital states are used to provide a visual display of power system and relay operation data captured during specific triggered events.

f) FILE SUPPORT

• Execution: Any EnerVista UR Setup file which is double clicked or opened will launch the application, or provide focus to the already opened application. If the file was a settings file (has a URS extension) which had been removed from the Settings List tree menu, it will be added back to the Settings List tree menu.

• Drag and Drop: The Site List and Settings List control bar windows are each mutually a drag source and a drop target for device-order-code-compatible files or individual menu items. Also, the Settings List control bar window and any Windows Explorer directory folder are each mutually a file drag source and drop target.

New files which are dropped into the Settings List window are added to the tree which is automatically sorted alphabetically with respect to settings file names. Files or individual menu items which are dropped in the selected device menu in the Site List window will automatically be sent to the on-line communicating device.

g) FIRMWARE UPGRADES

The firmware of a C70 device can be upgraded, locally or remotely, via the EnerVista UR Setup software. The corresponding instructions are provided by the EnerVista UR Setup Help file under the topic “Upgrading Firmware”.

Modbus addresses assigned to firmware modules, features, settings, and corresponding data items (i.e. default values, minimum/maximum values, data type, and item size) may change slightly from version to versio n of firmware. The addresses are rearranged when new features are added or existing features are enha nced or modified.

EEPROM DATA ERROR message displayed after upgrading/downgrading the firmware is a resettable, self-test

The message intended to inform users that the Modbus addresses have changed with the upgraded firmware. This message does not signal any problems when appearing after firmware upgrades.

4.2 EXTENDED ENERVISTA UR SETUP FEATURES 4 HUMAN INTERFACES

NOTE

4.2EXTENDED ENERVISTA UR SETUP FEATURES 4.2.1 SETTINGS TEMPLATES

Setting file templates simplify the configuration and commissioning of multiple relays that protect similar assets. An example of this is a substation that has ten similar feeders protected by ten UR-series F60 relays.

In these situations, typically 90% or greater of the settings are identical betwe en all devices. The te mplates feature allows engineers to configure and test these common settings, then lock them so they are not available to users. For example, these locked down settings can be hidden from view for field engineers, allowing them to quickly identify an d concentrate on the specific settings.

The remaining settings (typically 10% or less) can be specified as editable and be made available to field engineers installing the devices. These will be settings such as protection element pickup values and CT and VT ratios.

The settings template mode allows the user to define which setting s will be visible in EnerVista UR Setup. Settings templates can be applied to both settings files (settings file templates) and online devices (online settings templates). The functionality is identical for both purposes.

The settings template feature requires that both the EnerVista UR Setup software and the C70 firmware are at versions 5.40 or higher.

a) ENABLING THE SETTINGS TEMPLATE

The settings file template feature is disabled by default. The following procedure describes how to enable the settings template for UR-series settings files.

1. Select a settings file from the offline window of the EnerVista UR Setup main screen.

2. Right-click on the selected device or settings file and select the Template Mode > Create Template option.

The settings file template is now enabled and the file tree displayed in light blue. The settings file is now in template editing mode.

Alternatively, the settings template can also be applied to online settings. The following procedure describes this process.

1. Select an installed device from the online window of the EnerVista UR Setup main screen.

2. Right-click on the selected device and select the Template Mode > Create Template option.

The software will prompt for a template password. This password is required to use the template feature and must be at least four characters in length.

3. Enter and re-enter the new password, then click OK to continue.

The online settings template is now enabled. The device is now in template editing mode.

b) EDITING THE SETTINGS TEMPLATE

The settings template editing feature allows the user to specify which settings are available for viewing and modification in EnerVista UR Setup. By default, all settings except the FlexLogic™ equation editor settings are locked.

1. Select an installed device or a settings file from the tree menu on the left of the EnerV i sta UR Setup main screen.

2. Select the Template Mode > Edit Template option to place the device in template editing mode.

3. Enter the template password then click OK.

4. Open the relevant settings windows that contain settings to be specified as viewable.

The software will prompt for a template password. This password must be at least four characters in length.

3. Enter and re-enter the new password, then click OK to continue.

The settings file template is now secured with password protection.

When templates are created for online settings, the password is added during the initial template cre ation step. It does not need to be added after the template is created.

d) VIEWING THE SETTINGS TEMPLATE

Once all necessary settings are specified for viewing, users are able to view the settings template on the online de vice or settings file. There are two ways to specify the settings view with the settings template feature:

• Display only those settings available for editing.

• Display all settings, with settings not avai l able for editing greyed-out.

Use the following procedure to only display settings available for editing.

1. Select an installed device or a settings file from the tree menu on the left of the EnerV i sta UR Setup main screen.

2. Apply the template by selecting the Template Mode > View In Template Mode option.

3. Enter the template password then click OK to apply the template.

Once the template has been applied, users will only be able to view and edit the settings specified by the template. The effect of applying the template to the phase time overcurrent settings is shown below.
