GE Digital Energy UR Universal Relay Series Revision 5.53 Release Notes GE Publication Number: GER-4362 Copyright © 2009 GE Multilin Overview Summary GE Multilin issues the UR 5.53 release that introduces new improvements for general and protection functions in the UR Family. Highlights of this release include: • L90: inter relay communication has been improved to cope with communication failures on twoterminals redundant channel with Multiplexers schemes, and three-terminal schemes. This document contains the release notes for the 5.53 release of the Universal Relay (UR) Family. Affected products: L90 Date of release: Dec 23th, 2009 • Firmware revision: 5.53 • • This document also comprises the release notes of previous 5.5x firmware versions. If users have existing UR Family relays installed with older version of firmware, they can download and install this new firmware to benefit from the enhancements described in this release note. If the user does not require these new features and enhancements, no upgrading of the relays is required. 1 UR revision 5.53 release notes Products Affected This release encompasses the following UR Family products: • • • • • • • • • • • • • • • • B30 Bus Differential System C30 Controller System C60 Breaker Protection System C70 Capacitor Bank Prot & Ctrl System D30 Line Distance Protection System D60 Line Distance Protection System F35 Multiple Feeder Protection System F60 Feeder Protection System G30 Generator & Transformer Protection System G60 Generator Protection System L60 Line Phase Comparison System L90 Line Current Differential System M60 Motor Protection System N60 Network Stability and Synchrophasor Measurement System T35 Transformer Protection System T60 Transformer Protection System Firmware Compatibility The new 5.53 firmware that is a part of this release is compatible with the UR series hardware version 4.00 and higher. The use of the new 5.53 firmware requires the EnverVista UR Setup software to be version 5.50 or higher. 2 UR revision 5.53 release notes FW 5.53 Release details In the following enhancement descriptions, a revision category letter is placed to the left of the description. Refer to the Appendix at the end of this document for a description of the categories displayed. L90 Line Differential System E L90’s redundant inter-relay communication for two-terminal schemes has been changed to ensure the correct data is received by channel two when data in channel 1 is looped back on the multiplexer side 553-1 Applicable: L90. FW version 5.53 introduces separate-receiving buffers per communication channel to the Inter-relay communication Modules. This ensures that, in redundant two terminal applications when channel one of the multiplexer is in the loopback mode (the data is looped back to the L90 by the multiplexer), any Direct I/O signals sent by the remote L90 relay via the second channel is not overwritten with the channel one looped back data. This could result in losing the Direct I/O signals on the local L90 relay. The firmware release 5.53 fixes the problem by ensuring the processing and data maintenance of Direct I/O signals are exclusive to each channel. If your line differential scheme is having direct communication between the L90 devices, this issue does not affect them. For customer having schemes with multiplexers, standard maintenance procedures request protection devices to be isolated from the breaker(s) when a function related to the protection elements within the device is being tested. If your maintenance procedures fit to this criteria, there is no risk of mis-operation on your system. Otherwise, your device FW version must be upgraded. H L90’s redundant inter-relay communication for two-terminal schemes has been changed to ensure relays in both terminals are still synchronized after performing a loopback test on the multiplexer 553-2 Applicable: L90. Some multiplexers available on the market, allow users to perform a loopback test on the local unit while still sending data to remote end. As a consequence L90s with redundant channels and communicating through this kind of multiplexers might lose synchronization between them while one channel is being tested (PFLL fail activated) and stay latched in that condition after the test. FW version 5.53 adds the “ID Fail” status to the data stream used for the inter relay communication modules. This “ID fail” status allows the remote L90 to know that the local L90 channel is under loopback test condition. The remote L90 will then use the data from the other channel (that which is not in loopback) for synchronization. This way synchronization is never lost. If your line differential scheme is having direct communication between the L90 devices, this issue does not affect them. 3 UR revision 5.53 release notes U L90’s inter-relay communication for three-terminal schemes has been changed to ensure communication is restored between all L90 devices when a channel failure condition is cleared. 553-3 Applicable: L90. As a standard behavior, a three terminal line differential scheme will raise “PFLL Fail” (synchronization) and “CH fail” operands on all three terminals when both communication channels fail on at least one terminal. However, if only one channel goes back to normal, L90s on all terminals might still show PFLL fail and CH Fail, and neither the communication nor the differential protection are restored. This issue only affects relays with FW version 4.93, 5.02, 5.47, 5.52 and 5.61. If your relay’s FW version is different to the ones mentioned above no action is required. 4 UR revision 5.53 release notes (previous) FW 5.52 Release details In the following enhancement descriptions, a revision category letter is placed to the left of the description. Refer to the Appendix at the end of this document for a description of the categories displayed. Bus Protection E Bus differential element “87B” to prevent mis-operation due to an unblocking command. Applicable: B30, B90. The 87B element has a “Block” setting that allow users to block the element’s operation previous or after a fault condition. If during a block condition generated after the 87B element operates, the fault condition is removed and then the block on the element is removed as well, the 87B element misoperates. This firmware release ensures that 87B will not misoperate when the block condition is removed under the described conditions. Users that have the “block” setting of the differential function set to disable, are not affected by this exception. If the block setting of the differential element is being used, it is recommended to upgrade the firmware. C70 H The Neutral current unbalance element “60N” has been modified to effectively operate when the element is set to a source different from source # 1. 571-2 Applicable: C70. The Neutral Current Unbalance element 60N operates as expected for fault conditions when the “Bank Source” setting of the element is assigned to SRC1. However, if this setting is assigned to any of the other available sources, then the Neutral Current Unbalance element may not operate for the fault condition as expected. Firmware version 5.52 ensures that the neutral current unbalance element “60N” will always operate under fault conditions when the “Neutral Current Unbalance # Bank Source” setting is configured to any source other than source #1. Customers with C70 relays and with Neutral Current Unbalance element Bank Source setting set to a source other than SRC1 are encouraged to upgrade to firmware version 5.52. Some protection elements may be assigned to source two (2) when the relay has more than one set of current inputs. If your 60N element is set this way, the issue will be detected during commissioning tests. If your C70 already passed the commissioning tests, no action has to be taken. 5 UR revision 5.53 release notes E Changes on the “Phase Current Unbalance Auto Setting” element ensures accurate compensation factors when phase and differential CT ratios difference is high. Applicable: C70. The “Phase Current Unbalance Auto Setting” Function has been improved such that the compensation factors, applicable to the “Phase Current Unbalanced” element, are accurately estimated even with high levels of CT mismatch. Previous FW version could calculate incorrect compensation factors in the case where there is a large difference between the “CT ratio of phase CTs” and “CT ratio of differential CTs” (E.g. Phase CT ratio 3300; Differential CT ratio 10). L90 F 87L element to ensure correct source reading when switching settings groups and having several local sources. Applicable: L90. The 87L element has been improved to guarantee that all required sources (as configured in the appropriate group settings) are read when switching from one setting group to another. Previous firmware version might read only the source assigned to group 1. This only applies to protection schemes that have more than one local-current source contributing to the differential current element, and then setting groups can be set to different sources. F L90’s redundant inter-relay communication for two-terminal schemes has been modified to prevent a mis-operation when a channel fail condition precedes a repeated loopback condition on the multiplexer side Applicable: L90. It has been determined that an L90 Line Differential Protection System applied to a two terminal redundant channel application could mis-operate during repeated loopback testing on the multiplexer if a channel fail condition is previously detected by the relay. Two cases of miss-operation have been reported from the installed base since 1999. The L90 relay accommodates loop-back testing by checking for the proper channel ID before using the data received. If the channel ID is incorrect, the data received is discarded. The relay also detects a failed channel when a channel is not connected or when bad packets are received. However, if channel failure is detected prior to the loop back condition (loopback test on the multiplexer), a race condition in the data validation logic could occur and allow the 87L element to miss-operate. For customer having schemes with multiplexers, standard maintenance procedures request protection devices to be isolated from the breaker(s) when a function related to the protection elements within the device is being tested. If your maintenance procedures fit to this criteria, there is no risk of mis-operation on your system. Otherwise, your device FW version must be upgraded U Improved two-terminal Inter relay communication ensures 87L goes back to normal after a channel fail and prevents events flooding Applicable: L90. This firmware version ensures that, for two terminal-single channel applications, the inter-relay communication link goes back to normal once a communication failure is cleared. Previous firmware version showed that, “channel fail” and “PFLL” operands oscillated every 10 seconds after a channel failure detection leading to filling up the event recorder with multiple events, and failure of 87L element to return to normal operation. L90s with firmware version prior to 4.61 are not affected by this issue. 6 UR revision 5.53 release notes U Changes on the three-terminal Inter relay communication ensure 87L goes back to normal when Channel and PFLL alarms are reset Applicable: L90. This firmware version ensures that, for three terminal applications, the inter-relay communication link returns to normal operation in the case that, in one terminal, both communication channels fail and then just one comes back. In previous version, “channel fail” and “PFLL” operands started to oscillate, so that one communication link didn’t return to normal operation. L90s with firmware version prior to 4.61 are not affected by this issue. M60 U Changes on the thermal overload element prevent permanent lockout after a motor thermal overload trip when the element is disabled or the relay is powered off. 571-3 Applicable: M60. When the thermal overload element “49” operates, it is intended to go to a lockout state until the motor temperature returns to a safe level. This is known as motor cooling time, and the thermal lockout automatically resets after this period. However, there were specific situations where the Thermal overload element may trip and stay permanently locked out unless an emergency re-start is performed. These conditions are: 1. When in thermal lockout state, the thermal element is disabled and, after the motor cooling time has elapsed, the thermal element is enabled again. It is important to remark that changing settings during a thermal lockout is not a normal procedure. 2. When in thermal lockout state, the relay is powered off and, after the motor cooling time has elapsed, the relay is powered on again. Under these conditions the thermal lockout remained on until an emergency re-start command was performed. Users who perform procedures as described above are adviced to update the FW version to 5.52. Common Protection and Control Elements M Sensitive directional power element has been changed to correctly update its actual value when the element is in blocked state. 571-5 Applicable: G30, G60, F60, M60, N60 This firmware version ensures that “sensitive directional power” actual value shown by the relay is being updated even when the “sensitive directional power” element is in blocked state. Previous firmware versions allow this value to freeze to the value the relay showed just before the element was blocked. This issue doesn’t affect the correct operation of the protection element and it ensures that the power actual value is updated independent of the element block state. 7 UR revision 5.53 release notes F Changes on the “Trip Bus Element” prevent mis-operation when the relay is powered up with the element being enabled. Applicable: F35. The F35 “Trip Bus Elements” (one to six) were enhanced to prevent misoperation when the setting “Trip Bus Function” is enabled when the relay powers up. If your F35 settings meet these conditions, you must immediately update your firmware version. B Two-terminals redundant Inter relay communication has been modified to prevent the local relay from rebooting if power cycled after the remote relay. Applicable: B30, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. This firmware version ensures that, for two terminals-redundant channel applications, the relay in one end would not reboot when it has been powered on after the relay in the other end. This issue does not affect relays with firmware version prior to 5.40. F “Restricted Ground Fault” element to ensure correct operation when phase currents are > 13*CT Applicable: T60, G30, G60 The “Restricted Ground Fault” element was enhanced to ensure the relay will operate correctly when currents incoming from phase CTs are higher than thirteen times the nominal CT current (13*CT). F The Split Phase element to ensure its proper operation on phases B and C when time delay setting is set to zero. Applicable: G30, G60. An enhanced “Split phase” element ensures a proper operation on detection of a split phase condition on phases B or C and having a time delay setting of zero. In previous firmware versions, the split phase element would not operate when detecting a split phase condition on phases B or C when the time delay was set to zero. E Neutral and Negative sequence directional elements “67N” and “67_I2” ensure proper selectivity when the negative sequence current value is zero. Applicable: C70, D30, D60, F60, G30, G60, L60, L90, M60, T60. Neutral directional element “67N” and Negative sequence directional element “67_I2” have an additional supervisor unit that blocks these protection elements if either the polarizing voltage or the operating current are below the cutoff levels. Current and voltage cutoff levels are defaulted at 0.02pu. E Distance elements have been improved to increase selectivity. Applicable: D30, D60, G60, L60, L90, T60. The distance protection algorithms were modified as follow: 1. The memory voltage element is now reset not immediately after all phase currents are below 0.05pu indicating that breaker is open, but delayed by 6 cycles. This gives distance elements opportunity to operate, when temporarily line current becomes less than 0.05pu with voltage below 0.8pu (creating conditions to reset memory voltage) as a result of a fault or remote/upstream breaker operation and then subsequently evolving fault on the protected line. 2. For phase and ground distance zone 2 only, there is a provision to start zone timer when other distance zones or loops pick up during the fault. This will allow not prolonging phase distance zone 2 operation, if 8 UR revision 5.53 release notes fault evolves from one type to another or migrates from the other zone to zone 2. Common zone 2 timer is achieved with appropriate settings in Trip Output element. 3. Ground distance element may operate now even if there is a zero-sequence source only behind the relay, such as in the case of the line terminated by a power transformer with grounded neutral. Before this change, ground distance required both zero-sequence and negative sequence current to discriminate fault direction and allow operation. These changes increase the distance elements selectivity ensuring additional tripping security. E Ground distance elements have been improved to increase selectivity when facing three-phase or phaseto-phase faults and remote single pole tripping. Applicable: D30, D60, G60, L60, L90, T60. The ground distance protection algorithm was modified to have an enhanced over-current supervision that incorporates a positive sequence restraint factor. Zero-sequence current is a vital quantity for ground distance elements correct operation. However, spurious zero-sequence current resulting from CT saturation and CT errors, switch-off transients during double-line and three-phase faults and system unbalance, may lead to improper operation of ground distance element. To increase ground distance security during multi-phase faults with specifically low settings of OC supervision, a positive sequence current restraint of 5% was added to over-current supervision. Now current value has to be higher than [In-0,05 x I_1] in order to release ground distance operation. This enhancement allows the ground distance element to deal with ground faults while having a remote single pole open scenario. These changes increase the Ground distance element selectivity ensuring additional tripping security. Communication C IEC61850 client/server communication to prevent UR relays from losing communication when two clients are polling data. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. When two or more IEC61850 clients were linked to one UR relay, and at least one of them was polling a report (buffered or not), all clients could lose connection in the event that, the client polling the report, was disconnected from the LAN. Then the relay has to be powered off and on to recover communications. This firmware version corrects this issue. E Changes on IEC61850 GOOSE messages prevent unwanted alarms Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. Now GOOSE messaging has a dynamic algorithm to estimate “time to live period”, which prevents the generation of unnecessary “Remote device off” Alarms. Previous firmware version could raise this alarm when communication channels and remote devices were linked. C Changes on the IEC60870-5-104 protocol prevents possible communications freezing when losing one of the masters. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. UR relays have been improved to prevent communication freezing when linked to an IEC60870-5-104 Master. In the Previous firmware versions relay communication could freeze on the condition that the IEC60870 master dropped after about 02 days of polling message integrity. 9 UR revision 5.53 release notes C Changes on IEC 61850 client/server communication ensures proper interaction with 02 Siemens SICAM PAS clients Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. The IEC61850 station bus communication has been enhanced to operate correctly when two connected SICAM PAS clients are recovering from broken link. Previous firmware version could allow one of the connected UR relays to re-start when experiencing that condition. E IEC61850 configurable GOOSE re-transmission time reduced. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. The retransmission rate of configurable GOOSE datasets 2 to 8 was modified to enhance speed from a rate of 100ms, 500ms, 1000ms to a speed of 100ms, 100ms, 100ms. G UR devices to show the encrypted form of the password when communicating with a PC through web browser software. 571-6 Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. The UR devices support communication through standard web-browser software such as Internet Explorer. Customers using this medium to access to the relay’s modbus memory map may see that the encrypted form of the password is not shown on the respective addresses (4000, 4002). This firmware version ensures the encrypted form of the password is shown in the respective address when users connect with the relay using web-browser software. E Faster Data File Transmission Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. UR Relays now use the TFTP ports to transmit data files reducing the transmission time. E.g. event records, oscillography, fault reports, data logger. E Preventing more than 5 IEC61850 Clients from connecting to the UR Applicable: B30, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60 The IEC61850 Client/Server protocol was enhanced to prevent more than 5 clients from simultaneously connecting to the UR device as is specified in the manual. In the previous version of the firmware, if more than 5 clients attempted to simultaneously connect to a UR device, the connection to the 6th and additional clients would remain open even after communications had ceased. By having these additional connections remaining open, the overall communications to the UR would be slower than desired. In this new version of firmware, a maximum of 5 IEC61850 clients can communicate to the UR at one time and thus, all connections will open and close correctly. C DNP 3.0 protocol to properly report internal time delays under DNP object 52 Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. The DNP3.0 protocol has been changed to accurately estimate and report the value of “time delay fine” that is comprised within the DNP 52 object. This time represents the period between the time of message reception and the time of message reply by the UR relay and helps the DNP master to calculate the delay on the serial wire. 10 UR revision 5.53 release notes PMU - Synchrophasor M 571-7 Changes on Synchrophasor Timestamp ensure the correct rollover of milliseconds’ field Applicable: N60, D60, L90, G60. During continuous polling of PMU data it was found that “the seconds’ field” of synchrophasors timestamp didn’t show the correct rollover from milliseconds approximately once every 45 minutes. As a consequence, every 45 minutes one package of PMU data may show an incorrect time stamp in the milli-seconds field. Firmware version 5.52 corrects this issue. Fault and Event Recorders R Event recorder to guarantee proper sequence of Contacts inputs events when having different debounce time. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. UR event recorder was improved to ensure that all contact input events are correctly sequenced by the event recorder. Previous firmware version could allow the event recorder to miss the correct order if two contacts inputs with different debounce time settings operated almost at the same time. This issue does not affect relays with firmware version prior to 4.60. R Fault Report to guarantee accurate records when VTs are in delta. Applicable: B30, B90, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, T35, T60. UR fault report algorithm has been improved to ensure prefault and fault voltage phasors are properly computed and stored within fault reports when VTs are in delta configuration and “VT substitution” setting is enabled. Also, the fault report is further enhanced to display only those elements that operated at trigger. R Data logger element has been modified to ensure the newest data is placed at the end of the queue when rolling over. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. This firmware version ensures the “data logger” element always displays the older data first followed by the newer data. Previous firmware versions may show the newest data at the start of the queue instead of at the end. Relays with firmware version previous to 4.80 are not affected by this issue Flex-Elements / Operands M Flex-elements to ensure accurate actual values when inputs are assigned to analog parameters that have a decimal point in the CT or VT ratio setting. Applicable: B30, B90, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. 11 UR revision 5.53 release notes UR Flex-elements were enhanced to show exact “Flex-element’s actual values” when their analog inputs, “InputPlus” or “InputMinus”, are assigned to parameters that have a decimal point in their scale factor. E.g. voltage values which VT ratio contains decimals such as VT 6900V: 120V = 57,5:1), frequency values. M Flex-elements to ensure accurate actual values when both inputs are assigned to Frequency values. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. UR flex-elements are improved to show precise “Flex-element’s actual values” when both analog inputs, “InputPlus” and “InputMinus”, are assigned to Frequency values. In such conditions, the previous FW versions could calculate the corresponding actual value incorrectly. Self-test Diagnostic D Internal Self-test diagnostic element to show the module type and location when detecting a faulty DSP module. Applicable: B30, B90, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. In this firmware version the self-test diagnostic messages will show where the failed module is located in the UR Chassis. Previous firmware versions would show the self-test error message “Module failure XX” only. This issue does not affect relays with firmware version prior to 5.50. Real Time Clock B Improved IRIG-B noise immunity. Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. IRIG-B inputs were enhanced to reduce noise sensitivity by rejecting short duration input pulses (lower than 250micro-sec). In previous firmware versions, on the condition that a “DC Shift” IRIG-B signal had been set and a high frequency noise came in through IRIG-B inputs, the relay could reboot. Platform D Preventing programmable push buttons from latching up when pressing more than one simultaneously Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. Internal control algorithm of programmable push buttons was improved to guarantee that none of them would latch when more than one button are pressed simultaneously. D Ensuring programmable push buttons reset when keeping them pressed for a period longer than the “Auto Reset Delay” setting Applicable: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L60, L90, M60, N60, T35, T60. Internal control algorithm of programmable push buttons was improved to guarantee that they would reset properly even if they were kept pressed for a period longer than their “Auto Reset Delay” setting. It only applies when the “Auto Reset Function” is set to “enable”. 12 UR revision 5.53 release notes (previous) FW 5.51 Release details In the following enhancement descriptions, a revision category letter is placed to the left of the description. Refer to the Appendix at the end of this document for a description of the categories displayed. E Increased sensitivity and security for the L60 87PC (Phase Comparison) function Applicable: L60 Fault detectors supervising the main 87PC Phase Comparison element have been modified to operate on the sum of currents from both breakers in breaker-and-a-half applications, and new fault detectors responding purely to the magnitude of positive- and negative-sequence currents have been added. For additional security in blocking schemes, additional timers for pickup delay and continuous keying after fault clearing have been added to better handle switching transients during external fault clearance. E Neutral Voltage unbalance compensation for phase shift in single-wye grounded capacitor banks Applicable: C70 The C70 Neutral Voltage Unbalance element was enhanced for single-wye capacitor banks where the neutral is connected to ground through a CT with a secondary sensing resistor. A new setting was added to compensate for the 90 degree shift between the voltage appearing across the sensing resistor and the neutral voltage on the bus. N EnerVista UR Setup support for the new enhanced vertical front panel. Applicable: entire UR family The EnerVista UR Setup software has been enhanced to support the new Enhance Vertical front panel. The software now supports orders codes that contain the new front panels as well as the graphical view of the front panel for viewing the display and LED’s and sending commands through the pushbuttons. N EnerVista UR Setup support for the UR switch module. Applicable: entire UR family The EnerVista UR Setup software has been enhanced to support the new UR switch module. Basic configuration and alarming can be performed directly through the UR setup software. Advanced switch configuration such as VLANs and QoS can be performed by clicking on the Switch Advanced Configuration menu item which will then launch the Advanced Web Management Software. E EnerVista UR Setup making the 3 User buttons available on the Front Panel graphical display Applicable: entire UR family The EnerVista UR Setup software was enhanced to make the 3 User buttons available on the graphical display of the front panel. In the previous version of the software, the User buttons used for remote controlling of the relay through the front panel was unavailable. 13 UR revision 5.53 release notes (previous) FW 5.50 Release details In the following enhancement descriptions, a revision category letter is placed to the left of the description. Refer to the Appendix at the end of this document for a description of the categories displayed. Ease of Use Enhancements N Enhanced Vertical Front Panel Applicable: Entire UR Family The UR Vertical Front Panel has been enhanced to provide expanded functionality and increased visualization to power system events. This enhanced vertical front panel can be purchased on new units ordered from the factory or as an upgrade kit for relays currently installed in the field. The enhanced front panel is completely backwards compatible with older units and firmware versions and can be installed without removing the relay from service. Enhancements to the UR vertical Front Panel include: Larger Display – The Enhanced Front Panel has a new LCD display that is brighter and is 2.5 times larger than the basic Front Panel. Lockable RS232 port – The new lockable RS232 port ensures that the communications cable is secure during configuration and relay interrogation. Six new User-Programmable pushbuttons – A new option has been added to Vertical UR’s that provide six new User-Programmable Pushbuttons for user operation. These fully configurable UserProgrammable Pushbuttons can provide control of power system equipment by users in front of the device. Easy labeling of User-Programmable LED’s – The method of labeling the User-Programmable LED’s has been enhanced to provide users with an easy method of customizing the text shown next to each LED. The Enhanced Front Panel comes with perforated template cards that can be run through a 14 UR revision 5.53 release notes standard printer and punched out to create customized labels. These labels can then be slid into protective pockets next to each row of LED’s using a simple tool that is included with the Front Panel.
