SECTION 1. GENERAL INFORMATION

WARNING

(EntelliGuard G only)
Pin Connector on back of all trip
The EntelliGuard TU Trip Unit is an electronic device that interfaces with a circuit breaker. It monitors current and/or voltage and trips the breaker in the event of an over­current or voltage related condition. It also provides protective relay functions, advanced metering, diagnostic features, and communications. The Trip Unit can be removed or replaced in the field by de-energizing and removing the cover of the circuit breaker.

The Trip Unit drives the circuit breaker flux shifter to provide the electromechanical tripping function. A user interface is provided on the front panel to allow adjustment of the Trip Unit’s parameters.

EntelliGuard TU Trip Unit has been designed to be plug and play compatible with previous generation trip units, MicroVersa Trip, MVT RMS-9, EPIC, MVT Plus, MVT PM, Power+, and ProTrip. In addition to trip unit upgrades,
Figure 1-1: EntelliGuard G Trip Units
40 Pin Connector on top
conversion kits are offered to upgrade ANSI type legacy breakers.

FRONT PANEL DISPLAY

The Trip Unit includes a graphical Liquid Crystal Display (LCD). The front panel is similar to those shown in Figure 1-1 through Figure 1-5.
When the trip unit is energized the LCD normally displays a menu of navigation options. If the trip unit is powered from an external DC supply, a backlight is provided and remains on. If the trip unit is powered from the circuit breaker’s Current Transformers alone there is no backlight, but the navigation menu is available as long as current flow is at least 20% of the breaker’s sensor rating. If the display is blank, pressing any key will turn on the menu using battery power.

ELECTRICAL REQUIREMENTS

Ensure only qualified personnel install, operate, service and maintain all electrical equipment.

EQUIPMENT INTERFACES

PowerBreak I, PowerBreak II, WavePro, AK, AKR, Conversion Kits (for GE and other manufacturer breakers) and EntelliGuard G Circuit Breakers.

Trip units do not require direct connections to the equipment. All trip unit connections external to the breaker are made through the circuit breaker secondary disconnect.

PowerBreak I, PowerBreak II, WavePro, AKR and EntelliGuard G Trip Units are powered from three different sources:

sufficient power to energize the LCD when at least 20% of the sensor's ampere rating is flowing.
the circuit breaker’s secondary disconnect, or from the GTUTK20 test kit, or from the portable battery pack, (TVPBP and TVPBPACC). Each GTU draws 90mA maximum.
when any keypad key is pressed. Battery power automatically turns off 20 sec after the last keypad press. The battery power supply is disabled when any current over 20% of the sensor rating is sensed through the current sensors. Breaker status (open/closed) is not reported under battery power.

RATING PLUGS & THE UNIVERSAL RATING PLUG

The EntelliGuard TU trip system is composed of trip units and trip unit rating plugs along with the sensors and wiring provided in the circuit breaker to support the trip. Rating plugs are used to lower the Long Time adjustment range of the sensor provided in the circuit breaker.
The EntelliGuard TU trip rating plugs are unique in that they can be used with multiple trip units and circuit breakers within a specific sensor range, rather than only with a single specific sensor. The trip rating plug catalog number identifies the rating as well as the minimum and maximum sensor rating the plug may be used with. Appendix B lists trip-rating plugs available for each sensor and their part numbers and the two-digit codes used within the trip rating plug catalog numbers to identify sensor current ratings.

ANSI and UL circuit breaker types use a fixed rating plug with a marked ampere rating. Trip units use the current sensors installed in the breaker.

A total of eight cycles are captured:

Four pre-trigger.
Four post-trigger.

24 VDC external power is required for waveform capture.

When waveform capture is executed, the following channels will be captured simultaneously: Phase A current, Phase B Current, Phase C Current, Phase N Current, Phase L1 voltage, Phase L2 voltage, Phase L3 voltage.

WFC captures 48 samples per cycle, per phase, at 50 hz and 40 samples per cycle at 60 hz – the same data it used for its protection algorithms. The GE Setup Software contains full Waveform retrieval and viewer capability. GE offers the software free via web download. There is a function in the software that allows you to clear captured waveforms. The GTU stores only one waveform record at a time.

There are COMTRADE format viewers available to interpret the file downloaded from the trip unit, but the GE Setup Software is able to display the waveform graphically.

Viewing the waveform capture is described in the setup software. Currently, the software must be in communication with the trip unit prior to and during the event in order for the event to be captured. After the capture the software will show a file is available. The user then uses the software to request the file, which is extracted from the trip unit. At that point the file can be saved off for external use, or it can be opened for viewing in the program’s waveform viewer.

Harmonic content is calculated from the waveform data by the Setup Software. There is no harmonic content calculation performed by the trip unit – the data is extracted from the data set by the GE Setup software.

1. While a waveform capture data (in COMMTRADE format) is in memory, a new event will overwrite the capture data in memory. Whether the waveform capture is disabled or not, no other event is entertained. Unless and until the waveform is read and cleared by master by issuing appropriate commands, any read of waveform capture data will return the same first waveform, even if other events have occurred in between.
2. When the Modbus master is reading captured waveform data and a valid Event (trigger) occurs (for which the waveform could be captured): This new event is ignored. Since the trip unit already has an event captured and hence responding for the same event, trip unit will ignore the latest event (trigger). The trip unit will start capturing the new waveform only after Master has read the complete waveform AND issued a

LONG TIME PROTECTION

Long Time Pickup

This setpoint establishes the breaker's nominal ampere rating, xLT, as a fraction of the rating plug value, xIn:

xLT = LT multiplier x xIn

The adjustment range for long time pickup settings is 0.50 to 1.00 times xIn in steps of 0.05. The pickup value has a 10% tolerance. The band is drawn at 1/(1+10%) and 1/1­10%). The actual long time pickup is increased by 12% over the nominal so that 100% nominal current may be carried indefinitely. So a 1000 A setting is placed at 1120 A with the minimum pickup drawn (left side of band) is 1088A, and the maximum pickup (right side of band) is drawn at 1244A. Figure 2-1 shows the Long Time pickup setting.
Figure 2-1: Long Time Pickup Settings

Thermal Long Time Overcurrent

The thermal I
T shape is similar to the typical curve of a thermal magnetic circuit breaker and matches the shape of many overcurrent devices used in industry today. The typical shape and range of settings may be seen in Figure 2-2. The range of time delays is shown in Table 2-1 at various multiples of nominal (100%) current setting. Drawn bands also include a mechanical constant time to account for circuit breaker operating and clearing time, which causes the slight widening of the band evident at the lower (right) end of the faster (lower) bands.

Long Time Delay

The trip unit provides up to 44 long time delay bands (only on trip unit models starting with “J”). Not all circuit breakers have all bands available. There are 22 bands using a logarithmic type curve resembling the overcurrent

Thermal Memory

The Long Time and Short Time pick up algorithm also includes a cooling cycle that keeps track of current if it oscillates in and out of pick up range. This Thermal Memory is also active in case the circuit breaker trips on Long Time or Short Time to account for residual heating in conductors. If a circuit breaker is closed soon after a Long Time trip or Short Time trip, a subsequent trip may happen faster than indicated by the time current curve due to the residual cable Thermal Memory effect. In trips without control power, the Thermal Memory is powered from the trip battery. The cooling algorithm requires up to 14 minutes to fully reset to zero.
Table 2-1 shows the nominal clearing and commit times for X multipliers of nominal pickup.
Table 2-1: Nominal Time Delays for Thermal Shaped Long Time Bands
Algorithm will not commit below 1.5 cycles, clearing time will not be less than 0.088 seconds.
Actual Long Time pickup is 112% of nominal pickup.

Fuse Shaped Steep Long Time Overcurrent

The optional steeper fuse characteristic is a straight line K=I

t shape for application in systems where fuses and circuit breakers are used together. Twenty-two different time bands are available in each trip unit. Figure displays minimum and maximum bands. Table 2-2 displays the nominal time delays for each of the 22 bands at various multiples of nominal current pickup.

Drawn bands also include a constant time component, which accounts for the slight widening evident in the time current curve at the lower (right) end of the faster (lower) time bands.

Short Time Pickup

The Short Time Pickup function establishes the current at which short time trip is activated. Short Time Pickup is with a multiple of the Long Time Pickup and the choices of pickup settings are from 1.5 to 12.0 times the Long Time setting, xLT, in steps of 0.5 xLT.
The maximum pickup depends on breaker type and frame as shown in Table 2-3, below:
The Short Time Pickup value tolerance band is approximately -9% to +11% of the set point based on a 10% current sensing accuracy with the pickup calculated with 1/ (1+Tolerance). The time current curve of short time pickup is shown in Figure 2-3.

INSTANTANEOUS PROTECTION

Adjustable Selective Instantaneous over current protection causes an undelayed breaker trip when the chosen current level and proper waveform is reached.

The pickup value may be set in steps of 0.5 xIn from 2.0 xIn to 15 xIn and steps of 1 xIn from 15 xIn to a maximum of 30 xIn. Greater than 15xIn is available only in trips provided with the “Extended Range Instantaneous” option on ANSI EntelliGuard G circuit breakers.

The maximum possible setting depends on the trip unit instantaneous option provided, the circuit breaker’s withstand capability and whether or not ST has been enabled.

When Instantaneous pickup is set above 15X without ST on, ST pickup is automatically switched on Default delay is automatically switched on at a minimum delay setting, unless otherwise set by the user. This is only applicable to EntelliGuard G.

Table 2-6: Maximum Instantaneous for Power Break I, Power Break II, WavePro and AKR Trip Units
or current limiting circuit breaker while interrupting in a current limiting manner. This allows the trip setting to be set much lower than optimally peak sensing trips and hence sensitive to lower arcing fault currents that could be causing an arc flash event.

Reduced Energy Let Through (RELT)

The EntelliGuard TU trip unit’s RELT capability provides the ultimate in user flexibility for wiring and controlling an alternate Instantaneous setting for temporary use to reduce personnel hazard.

All versions of the EntelliGuard TU trip units are available with Reduced Energy Let-Through (RELT) Instantaneous protection. This optional feature allows the trip unit’s Instantaneous Protection pickup threshold to be temporarily set lower when personnel are in close proximity to the circuit breaker. In the event of a fault, the trip unit will respond sooner, minimizing damaging arc flash energy. Once personnel are safely clear of the area, RELT is disengaged, returning the system to its normal Instantaneous settings. The RELT setting is independent of the normal adjustable selective Instantaneous. Even if the normal instantaneous is not enabled, by turning on RELT the instantaneous will then be enabled.
The Instantaneous pickup accuracy is +10%. On certain ANSI trip units with the user-selectable switchable instantaneous over current an additional value of OFF appears at the end of the listing of numerical values. Note that if Short Time Delay is set to off, you will not be able to also turn off Instantaneous.

When Instantaneous pickup is set above the maximum allowed for the CB without ST on, ST pickup is automatically switched on at a default delay is automatically switched on at a minimum delay setting.

WaveForm Recognition vs. Peak Sensing

WFR is the standard algorithm used in the normal instantaneous trip function for all CB versions except Power Break I. The WFR algorithm is specially designed to optimize selectivity while achieving fast instantaneous tripping of the circuit breaker. The algorithm’s measurements act as a proxy for measuring energy and hence are able to discern a fault current from a peak-let­through current allowed to flow by a current limiting fuse
The pickup value may be set in steps of 0.5 xIn from 1.5 xIn to 15 xIn or the maximum allowed instantaneous pickup for the particular circuit breaker type, rating and size. The RELT Instantaneous pick up clears fault current in 50 milliseconds or less. The maximum setting depends on the trip unit catalog number, breaker type and frame, and whether or not ST is enabled. See Table 8.
Clearing times for the various instantaneous functions vary by circuit breaker. The RELT function clearing time is 0.042 seconds for EntelliGuard G at 60Hz and 0.05 seconds at 50Hz. The adjustable selective instantaneous is 0.05 and
0.06 seconds at 60 and 50 Hertz respectively. For Power Break II, AKR, and WavePro circuit breakers the clearing times are 0.05 and 0.058 seconds for RELT and selective instantaneous respectively at 60 Hz. Power Break does not offer the selective Adjustable Instantaneous or RELT function. Instantaneous clears in 0.05 seconds for Power Break versions of the EntelliGuard TU trip unit.
When the RELT option is configured in an EntelliGuard TU Trip Unit Digital Input 1 and Digital Output 1 are automatically and permanently configured to function with RELT. RELT is a factory installed option—it cannot be “turned on” if it is not purchased as an option. The Digital Output will be energized whenever RELT protection is engaged. The Digital Input can be wired to one or more external contacts, such as a light curtain, to engage RELT when someone is within range of the equipment.

RELT capability may be provided on a trip unit with or without 24VDC control power.

When 24 VDC/AC is provided to the RELT input (input 1), the trip unit will use the set RELT Instantaneous trip setting.

Without control power connected to the trip unit permanently, indication that the trip unit is in the RELT mode may not appear on the main screen. The trip unit must be permanently connected to 24VDC control power
A RELT Switch Kit (catalog #GTURSK) can also be purchased to add a RELT switch to existing breakers. The kit includes the selector switch, LED bulb, NO/NC contacts, 8 feet of wire with spade connectors. The LED Bulb burden is 0.84 watts and the color of the switch is blue.

Ground Fault CT

This protection element is available only on the EntelliGuard G. It is typically utilized for multi-source Ground Fault (MSGF) applications in ANSI/UL applications where sensor data must be shared among multiple trip units on systems with multiple sources connected in parallel. Contact your local sales office or the Burlington factory for details on GE’s recommended MSGF implementation. When GF CT is specified in a breaker, a special “interposing CT” is installed in the breaker that is wired between the breaker’s secondary disconnect and the trip unit’s CT inputs. The full scale output of this CT is
1.54mA at 100% of external sensor.
RELT instantaneous allows the minimum threshold to go to 1.5X.

GROUND FAULT PROTECTION

ALARMS

Ground Fault Alarms

The Ground Fault alarm DOES NOT issue a trip event. If tripping on ground fault is required order LSI
not LSIGA. Instead it can turn on a digital output if an output is configured for it. It will always turn on an indication in the Modbus register map. The output can be used to turn on a light or other signal but it WILL NOT GENERATE A TRIP EVENT.

All GTUs with a Ground Fault trip can also send a signal after the trip event that a GF occurred.

Current Alarm

The trip unit provides two current alarms. These alarms will trigger an alert when current consumption exceeds their setpoints. This is useful for implementing load shedding processes, and serves as an alert to impending Long Time pickup. The alert can be signaled either via communications or via digital output. The Current Alarms’ ON/OFF pickup settings are 0.5 to 1.0 xIn in steps of 0.05.

The trip unit does not allow the current alarm OFF setpoint to be set above the ON setpoint.

If the highest measured phase current goes above the Current Alarm ON setpoint and remains above the setpoint for more than 60 seconds the alarm will be triggered. If the current falls below the Current Alarm OFF setpoint for more than 60 seconds while the Current Alarm is active, the alarm condition will be cleared.

If the Zone Selective Input goes off while the restrained settings are in effect, they will remain in effect for 50 milliseconds. After that, the unrestrained settings will go into effect.

ZONE SELECTIVE INTERLOCKING

Zone -selective interlocking coordinates breakers so that the downstream breaker is allowed the first opportunity to clear a fault or overload event.

The optional Zone Selective Interlocking (ZSI) function operates with a group of series-connected breakers. ZSI is achieved with the use of the TIM1 module or an equivalent GE qualified and recommended device.

There are two sets of settings in a breaker used in a Zone Selective Interlocking system. The normal or “unrestrained” setpoints are the main over current protection setpoints. A second set of ZSI or “restrained” setpoints are included for each interlocked protection element – GF, ST, and Instantaneous.
If a protection element, such as Ground Fault, goes into pickup and the Zone Selective Interlock input is active, the “restrained” or ZSI settings will be in effect. If the Zone Selective Interlock input is not active when the GF element
the trip unit enters Short Time pickup and the ZSI input is OFF, these settings are in effect. In a ZSI configuration these settings are optimized for protection of the cable/bus directly below the breaker, and not for selectivity with downstream breakers.
If the trip unit enters Short Time Pickup and the ZSI input is ON, these settings are in effect. This setting is intended to provide selectivity with the downstream breaker, so it will typically be set longer, to give the downstream breaker a chance to clear the fault.

In Power Break II and Spectra MicroEntelliGuard Circuit Breakers the "T" option only enables instantaneous ZSI as an output to interlock with upstream circuit breakers such as a GE WavePro, AK, AKR, Conversion Kits or new EntelliGuard G (ANSI or UL489). The T option requires 24 VDC external power. The T option does not modify IOC
timing on PowerBreak I, PowerBreak II and Spectra MicroEntelliGuard circuit breakers.
Figure 2-5: Restrained ZSI Settings

ZSI Option

Two Zone- Selective-Interlocking options may be purchased with each trip. Option "Z" or option "T". Option Z allows the user access to short time or ground fault ZSI.

The user may enable or disable either or both. The "T" option adds Instantaneous ZSI capability. Instantaneous ZSI may be enabled or disabled by the user at any time.

Use of the short time or GF ZSI in a CB requires that the user set two different delay and slope bands for ground fault or short time depending on which he has enabled.

The upstream breaker uses the ST ZSI and/or GF ZSI delay bands and slope, and/or transition to a delay Instantaneous if it receives a downstream ZSI signal.

The desired ZSI (ST and/or GF and/or Instantaneous) must be selected in order for the downstream breaker to issue a ZSI signal, and the upstream breaker to act upon this signal. If the ZSI setting is set to OFF no ZSI output signal is generated.

The ST ZSI Delay Bands are independent and have the same bands available. Slope settings may also be interlocked.

INTERRUPTION PROTECTION

Making Current Release (MCR)

Every EntelliGuard G circuit breaker uses a making current release. The making current release varies per circuit breaker Envelope and is related to the circuit breaker’s close and latch rating.

The MCR pickup is activated at the time the circuit breaker closes and for six cycles thereafter. When the six cycles are over, the threshold changes to the HSIOC pickup setting.

High Set Instantaneous Protection (HSIOC)

HSIOC is also known as Override Pickup. Some of the trip units on EntelliGuard G circuit breakers may be provided with an override instantaneous trip.

Whether such a trip is provided or not depends on the circuit breaker within which the trip is installed. If the circuit breaker’s withstand lcw is equal to the short circuit rating then the trip will not have an override pickup. If the withstand rating is lower than the short circuit rating then the trip will enable override protection of the circuit breaker at the short time withstand rating level.

In UL 489 circuit breakers the HSIOC setting is nominally at 107% of the Icw for the circuit breaker. Taking tolerance into account, the override’s minimum trip is at 100% of the circuit breaker’s Icw.

In UL 1066 (ANSI) circuit breakers the HSIOC setting is also at 107% Icw if the adjustable selective instantaneous is ON. If the adjustable selective instantaneous is OFF then the HSIOC nominal pick up is at 98% of the circuit breaker’s Icw and, considering tolerance, the minimum pickup is at 91% of the circuit breaker’s Icw.
The BIM contains information that describes the breaker configuration to the trip unit. The trip unit extracts information on Sensor Rating, Interruption Rating, and pole configuration from the BIM. This is a one-time event that occurs when a new trip unit is first powered up in a breaker. Every time the trip unit powers up in the breaker from that point forward, it compares information in the BIM to the information it initially read and stored. If the information does not match the trip unit will immediately trip the breaker and set a BIM Error Flag, and record a BIM error trip event. In effect, the trip unit “marries” the breaker.
If a BIM read fails the trip unit will not open the breaker, instead it will modify its internal configuration to match the AIC rating of the least capable breaker in the family. The trip unit will periodically read the BIM after that, and on a successful match the original settings will be restored. While the BIM error persists a BIM Err message will be
The “Universal Trip Unit” can be used as a replacement for any trip unit. The Protection and Advanced Features of the Universal trip unit should match the configuration of the trip unit being replaced to maintain the same functionality. The Universal trip unit is programmed with minimum values for all protection, and it will automatically read the BIM values from the first breaker it is installed in. This will force the Universal Trip Unit to assume the configuration of the trip unit it is replacing. Once this process is complete, the Universal Trip Unit cannot be moved to another breaker – it “marries” the breaker.

BIM Transaction Details

On power up the trip unit immediately queries the BIM for local breaker configuration information.

Since there is no match:

Power Break I, WavePro and AKR circuit breakers do not employ an override function. Power Break II circuit breakers use a mechanical override function.

Voltage Unbalance

Upon power-up the trip unit reads BIM ID
If there is no match:
o Breaker trips Note: Software Revision 08.00.23
and great, If a BIM read fails the trip unit will not trip the breaker, instead it will modify its internal configuration to match the AIC rating of the least capable breaker in the family. The trip unit will periodically read the BIM after that, and on a successful match the original settings will be restored. While the BIM error persists a BIM Err message will be displayed on the LCD.

o GTU shows BIM ID Mismatch Error

o GTU registers a BIM Trip Event

Under certain circumstances, it is possible to reconfigure a trip unit so that it can be installed in a different circuit breaker. This involves “divorcing” the BIM and trip unit so that the trip unit can be “married” to a different circuit breaker.

1. Install the trip unit on the target breaker. On power up the breaker will be tripped due to BIM error.

2. BIM mismatch will be indicated.

3. Press Right + Left + Up simultaneously.

4. “BIM OK” will flash in the upper left corner of the LCD display if marry succeeded

5. “BIM ERROR” will show if the marry failed.

Upon execution of the procedure, GTU will upload the data if the breaker is open and the following data in the BIM matches the GTU data programmed in the factory:

This function compares the highest or lowest phase voltage with the average of all three phases and initiates a trip if the difference exceeds the set point.

The number of outputs available varies by breaker. These are relay contact outputs to the secondary disconnect. Each output can be configured per Table 2-15.
The contacts are rated for

Power Break I, Power Break II, WavePro, AK, AKR and Conversion Kit Trip Units have one output relay. EntelliGuard G Trip Units have two output relays. The relay output can be assigned to the following functions:

• Group 1 – GF Sum and GF CT alarm only. Does not latch.
Group 2 – Overcurrent (LT, ST, IOC, GF, CT GF). Latches
Group 3 – Protective Relay. Latches if trip.

The trip units must have the specific option (as an example protective relay must be enabled in order for protective function to actuate the relay) enabled in order to actuate the relay.

Fan/Command Close Control

EntelliGuard trip units include an output dedicated to controlling either an external breaker cooling fan (5000A WavePro and AKR breakers only) or a remote close accessory (EntelliGuard G breakers only). Breaker documentation provides wiring information.

For WavePro and AKR breakers, the trip unit automatically calculates cooling requirements and activates the fan control output to maintain the breaker’s operating temperature.

For EntelliGuard G breakers, the remote close command is available via Modbus command. Issuing command 111 will

Settings Description

The following are descriptions of the effects of each accessory switch when it is enabled:

If Bell Alarm or Bell Alarm with Lockout is set to Shunt Trip, an opening generated by a Shunt Trip will cause the Bell Alarm contacts to change state.
If Bell Alarm with Lock-out is set to over current trip, a fault generated by LT, ST, GF, and/or Instantaneous will cause the Bell Alarm contacts to change state.

Bell Alarm Operation – EntelliGuard G breakers

The EntelliGuard G breaker has a mechanical lockout built into the breaker’s trip mechanism. The lockout actuator is always triggered when the flux shifter actuator “trips” the circuit breaker. The breaker’s mechanical lockout is not actuated if the breaker is “opened” using the front panel pushbuttons, or an optional shunt trip accessory.
There are two modes of operation for the Lockout button in UL & ANSI applications – MANUAL and AUTOMATIC. The trip unit’s Lockout button configuration is fixed based on the catalog number of the trip unit. MANUAL or AUTO operation is fixed at the factory, and cannot be changed. Do not attempt to rotate the knob as it will damage the locking mechanism.
In MANUAL mode the breaker’s lockout actuator is allowed to travel to its “triggered” position. As the lockout trigger extends from the breaker mechanism following a flux shifter operation, it pushes the knob on the front of the trip unit out. At this point the breaker mechanism is “locked out” and cannot be closed until the mechanical lockout is manually reset. Reset is accomplished by pushing in the button on the trip unit until the breaker lockout is reset.

20 ©2012 General Electric All Rights Reserved
In AUTOMATIC mode the breaker’s mechanical lockout actuator is physically restrained from traveling to its “triggered” position by the fixed knob on the trip unit. In other words, the mechanical lockout is fired when the flux shifter operates, but the trip unit’s knob “automatically resets” the lockout so that the breaker can be reclosed without manual intervention.

There is an option bell alarm contact accessory that provides a signal whenever the breaker’s mechanical lockout operates. In MANUAL mode this contact will remain closed as long as the lockout reset button is extended. In AUTO mode this contact will close briefly when a trip occurs, but does not latch. The dwell time of the contact in AUTO mode is on the order of a few milliseconds – typically not enough to be useful for control purposes.

Current alarms can be configured to actuate relay outputs when they go into pickup. They also have status flags that can be monitored over Modbus.

The ON setting determines the level, as a percent of rating plug current, where the current alarm will pickup.

If the highest measured phase current exceeds the pickup threshold for more than 60 seconds, the alarm will activate. Setting range is 50% to 100%.

Once in pickup, if the highest measured phase falls below the OFF threshold for more than 60 seconds, the alarm will drop out.

BELL ALARM LOCKOUT (PBII AND WAVEPRO ONLY)

WavePro, AKR and PB1 has a factory installed Bell Alarm with Lockout option that is triggered by the mechanism, not the trip unit. So no special configuration is needed on AKR or PB1.

What this shows:
Metering values are dependent on the accuracy of the current sensors in the breaker, see table below. Current sensors in breakers are designed to be more accurate at 85% of current and greater than 100%, seeing their purpose is protection. If you see negative or non­directionally correct values check your power direction or your voltage configuration. The frequency is determined from the current. Current sensors are designed to be more accurate/linear at full load current and above (where the protection needs to be). The table below shows the accuracy of the reading based on the percentage of the sensor. This is consistent across all breaker types.

CURRENT METERING DISPLAY

The level of current flowing in each breaker phase.

Phase current metering is a standard feature of every GTU.

Neutral current display is optional and depends on the configuration of the circuit breaker.

With 24V external power, metering data will be displayed down to 8% of the installed sensor rating.

Without 24V external Power, the primary current flow needs to cross the self-power operating threshold which occurs between 10% and 15% of sensor before any metering activity occurs. If metering is required below this level, an external means of powering the trip unit will need to be provided, because the breaker CTs are not capable of generating enough energy to operate the trip unit below this threshold.

When this error is displayed the trip unit uses its lowest protection settings.

The rating plug error is generated under the following conditions:

1. The rating plug is not installed.

2. The rating plug is not fully inserted into the trip unit.

3. The rating plug value is outside the range allowed for the breaker’s sensor. For example, plugging a 4000A rating plug in a 400A sensor circuit breaker will generate this error or a 400A plug installed in a 4000A Sensor Circuit Breaker

4. For IEC or Euro configurations, where the trip unit rating is set programmatically, use of a rating plug other than the UNIVERSAL type (The catalog number for a universal rating plug is GTPUNIVU0000) will generate this error.

A Rating Plug error of some sort exists. The error can be cleared by installing the correct rating plug.

BIM ERROR MESSAGES

The Breaker Information Module (BIM) is an electronic rejection feature on EntelliGuard G Breakers only. When a GTU powers up the first time in contact with a BIM, it “absorbs” the BIM data and configures itself to match.

REDUCED ENERGY LET-THROUGH (RELT) SWITCH WIRING

The RELT switch may be connected to a manually operated two-position switch, a remote sensor, or both simultaneously. The EntelliGuard TU trip unit provides a feedback capability directly from the trip so you know the signal got to the trip unit and the settings have changed. Optionally, an indicating light may also be connected to the source of control power so the user knows if control power is available to change the setting. The trip unit does not require its own control power to accept a RELT input and change the Instantaneous trip pick according to the user settings. However, if control power is available to the trip unit, the feedback signal will function immediately, rather than when the trip unit becomes self-powered through its load current.

If a GTUTK20 test kit is not available you can create your own test kit communications cable, using the following pin assignments:

: Modbus RX
: Modbus TX
: +24VDC
: 24V Return

It is also possible to provide power to the trip unit through the secondary disconnect on breakers so equipped, eliminating the need to supply 24V through the test kit port.

Connection to computers lacking a 9 pin serial port may be done reliably through a USB-to-serial converter readily available at most office supply stores.

MODBUS RTU

Modbus is a master-slave protocol where a single host or master device initiates and controls all communication with the other devices (or slaves) on the network. The hardware interface is implemented as duplex two-wire RS­485, where data are transmitted and received in separate time slices. Per the EIA-485 standard the number of devices that can be connected on a single communication port is limited to 32 (including the master).
Please refer to the EIA-485 standard for complete details of
the physical interface including cabling, termination, and shielding.

Modbus Address Setting

In a Modbus RTU Network, each EntelliGuard Trip Unit module must have a unique address that can be set from 1 to 247. Addresses do not have to be sequential, but no two units can have the same
address.
Generally, each unit added to the
link uses the next higher address, starting at 1. The Modbus slave
address can be set using the keypad.

The Modbus slave address configuration can be set using the LCD keypad, or over Modbus communications.

For LCD configuration, navigate to the Modbus Settings
window under the SETUP main menu item. Use the up and down arrows to set the address to the desired value.

Modbus Baud Rate and Port Configuration

The EntelliGuard G Trip Unit supports the configured baud rate settings listed below, which can be set using the keypad. The Modbus Communications parameter setting screen is shown In Illustration to the left. The EntelliGuard Trip Unit supports the configured baud rate settings listed below, which can be set via keypad. The first number is the baud rate (300– 19,200), the first digit after the
dash is the number of data bits (fixed at 8), the letter represents the parity setting (N = none, E = even, O = odd), and the last digit is the stop bit.

Modbus Network Configuration

Figure 8-1 illustrates the standard two-wire Modbus topology. To minimize the effects of reflections from the ends of the RS-485 cable caused by impedance discontinuities in the system, a line-terminating RC network must be placed at each end of the bus, as illustrated in Figure 8-1. The simplest solution is to connect the terminator at the communication terminals of the devices at each end of the bus.
In most cases, pull up and pull down resistors are not required.
polarization, or if the master device does not provide proper polarization, then a pair of resistors must be attached to the RS-485 balanced wire pair, as follows:
Pull-up resistor to 5 V on the positive line
Pull-down resistor to common on the negative line

These resistors must be between 450 Ω and 650 Ω, and are selected based on the maximum current flow permitted by the connected devices. The latter may allow a higher number of devices to be connected to the serial bus.

If one or more connected devices require

RS-485 Termination Considerations

Per the EIA485 standard, every RS-485 network must be terminated at each end. GE recommends the SCI Terminator Assembly, part number 1810-0106 for these terminations. This terminator is applied at the first and last device in a Modbus network chain, wired across the RX and TX terminals. For trip units, the terminator can be located at the secondary disconnect of the circuit breaker.

You can fabricate terminators using 120 Ω 5% ¼ watt resistors in series with 50V 120pf capacitors.

Grounding Shielding Considerations

Figure 2-6 illustrates correct wiring for communications
and shield grounding. Follow this example to create a secure grounding point for each device on the network. Any surge will dissipate locally without being carried up or down the network to other devices, thus minimizing the chance for damage to devices due to surge or EMI.

RS-232 and RS-485 Connections

On the front panel of the EntelliGuard Trip Unit is a 15-pin connector for the RS-232 Modbus connection. This connector mates with a cable supplied with the GTUTK20 Digital Test Kit.

If the trip unit and circuit breaker are equipped with
optional RS-485 Modbus support, then the secondary disconnect of the circuit breaker will have connections designated for Communications. Two wires (RX and TX) are required for Modbus.

These parts are as follows:

RTU transmission. The device address is a number limited to the range of 0–247 and is associated with a single device configured with a matching address. This device receives and processes the transmission from the master. Only the addressed slave device responds to a transmission beginning with this address. A device address of 0 indicates a broadcast command.

Codes between 1 and 127 are defined as Modbus RTU functions. If a slave device responds with a function code with the most significant bit (MSB) equal to 1 (or equivalently a function code greater than
127), then the slave device did not perform the commanded action and is signaling an error response.

Modbus RTU Message Format

The Modbus RTU protocol is strictly based upon a transaction scheme in which a master device generates a query and a slave device replies with a response. Each
– This field contains a variable number of bytes, depending on the function performed. Data may contain addresses, actual values, or setpoints.
– This is a two-byte error-checking code, known as a Cyclic Redundancy Check. The Modbus RTU standard requires each message to have a two-byte CRC (commonly known as CRC-16 for 16 bits of error checking) to be appended to every transmission.
If the EntelliGuard Trip Unit detects a CRC error in a received Modbus message, the EntelliGuard Trip Unit does not respond to the message. An error in the CRC calculation indicates that one or more bytes of the transmission were received incorrectly, so the entire transmission is ignored, preventing an unintended operation.

The CRC-16 calculation is an industry standard method used for error detection.

Function Code 03H

For the EntelliGuard Trip Unit implementation of Modbus, this function code can be used to read any setpoints (“holding registers”). Holding registers are 16 bit (two byte) values transmitted high order byte first. Thus all EntelliGuard Trip Unit setpoints are sent as two bytes. The maximum number of registers that can be read in one transmission is 125.

The slave response to this function code is the slave address, function code, a count of the number of data bytes to follow, the data itself and the CRC. Each data item is sent as a two byte number with the high order byte sent first.

Read Actual Values
For the EntelliGuard Trip Unit implementation of Modbus, this function code can be used to read any actual values (“input registers”). Input registers are 16 bit (two byte) values transmitted high order byte first. Thus all EntelliGuard Trip Unit Actual Values are sent as two bytes. The maximum number of registers that can be read in one transmission is 125.

The slave response to this function code is the slave address, function code, a count of the data bytes to follow, the data itself and the CRC. Each data item is sent as a two byte number with the high order byte sent first.

:

For example, consider a request for slave II to respond with 3 registers starting at address 006B. For this example the register data in these addresses is listed below:

Store Single Setpoint

This command allows the master to store a single setpoint into the memory of an EntelliGuard Trip Unit. The slave response to this function code is to echo the entire master transmission.

For example, request slave 17 to store the value 2 in setpoint address 215 (00 D7). After the transmission in this example is complete, setpoints address 215 will contain the value 2. The master/slave packet format is shown below:

Table 8-5: Modbus Packet Format for Function Code 06H
:
:
Preset Multiple Registers
Store Multiple Setpoints
This function code allows multiple Setpoints to be stored into the EntelliGuard Trip Unit memory. Modbus “registers” are 16-bit (two byte) values transmitted high order byte first. Thus all EntelliGuard Trip Unit setpoints are sent as two bytes. The maximum number of Setpoints that can be stored in one transmission is dependent on the slave device. Modbus allows up to a maximum of 60 holding registers to be stored. The EntelliGuard Trip Unit response to this function code is to echo the slave address, function code, starting address, the number of Setpoints stored, and the CRC.
For example, consider a request for slave 17 to store the value 00 02 to setpoint address 00 D7 and the value 01 F4 to setpoint address 04 5D. After the transmission in this example is complete, EntelliGuard Trip Unit slave 17 will have the following setpoints information stored: The master/slave packets have the following format:

ERROR RESPONSES

When an EntelliGuard Trip Unit detects an error other than a CRC error, a response will be sent to the master. The MSBit of the FUNCTION CODE byte will be set to 1 (i.e. the function code sent from the slave will be equal to the function code sent from the master plus 128). The following byte will be an exception code indicating the type of error that occurred. Transmissions received from the master with CRC errors will be ignored by the EntelliGuard
Trip Unit.

The slave response to an error (other than CRC error) will be:

PRACTICAL MODBUS SETUP

This section is intended to give you a quick and simple checklist to run through when commissioning an EntelliGuard Trip Unit on a Modbus Network. The goal is to give you some concrete steps to get your device up and running quickly by eliminating some of the guesswork.

Step 1: Set up the Serial Port on the Master Device

a. If your computer does not have a built-in 9 pin serial
port, you will have to attach a USB-to-serial adapter. These devices are readily available at most office supply stores or online. For best results, buy a name brand. Be sure to install the driver software that comes with the device.
b. Once the serial port hardware is enabled on the
computer, determine which “logical port” (COM1, COM2, etc.) the computer has assigned to the port you plan to use. This information is available in the “Device Manager” function of Windows. Consult the web or your computer’s help facility for information on how to access the Device Manager.

In this example, a USB-to-serial port has been configured as COM1, and would be the port you would use to communicate with the trip unit.

Step 2: Configure the Communication Settings on the Trip Unit: Baud Rate, Parity, Stop Bits, Modbus Slave Address/ID

Step 3: Supply 24VDC to the Trip Unit, and Connect the Trip Unit to the Computer

You can connect a test kit between the computer and the 15 pin front panel port, or you can wire to the RS-485 terminals on the circuit breaker secondary disconnect.

Step 4: Configure the Master’s Communication Parameters

Modbus Address matches the trip unit
Baud Rate matches trip unit
Parity matches trip unit
Stop bits equals trip unit
Modbus requests are made using “Modbus RTU Serial”

Step 5: Attempt to Communicate with the Device

The registers listed below will return easily identified values that can be confirmed by reading the same setting from the device via LCD. This gives you instant feedback on whether the system is properly configured or not.

a. Read Modbus address.

add 40001 for an address of 40212.

PROFIBUS DP-PARAMETERIZATION

The GTUsupports parameterization. The relay keeps its user parameter data / setpoints in a non-volatile memory and does not need device related parameterization during startup of the DP master.

GTU can be parameterized via Profibus Class 1 using Profibus parameterized service. In this case only default configurations are allowed.

COMMUNICATION SETUP AND STATION ADDRESSES

The Profibus-DPV1 basic configuration has one DP master and one DP slave. In a typical bus segment up to 32
©2012 General Electric All Rights Reserved
stations can be connected (a repeater has to be used if more than 32 stations operate on a bus). The end nodes on a Profibus- DP network must be terminated to avoid reflections on the bus line.
During projecting of the bus structure ensure that the bus line is segmented dependent upon the length of the branch lines, the maximum cable length, and the number of bus stations. The allowable lengths are dependent upon transmission speeds and are specified in the Profibus standard DIN 19245-3 and in other publications dealing with this topic.

The Profibus bus address (MAC ID) of the GTU slave, which has a range from 1 to 125, can be set via the front cover switches. At power up, the GTU reads its address from the two rotary switches on its front and initializes the bus communication. Changes of the station address take effect with the next reset or power up.

The GTU supports auto-baud rate detection. The available baud rates and other slave specific information needed for configuration are in the GTU GSD file, which is used by a network configuration program.

To communicate with a Class 1 master (PLC) in a system, the GTU GSD file is required.

PROFIBUS GTU DP CYCLIC DATA

The cyclic data is a fast process data transfer between the Profibus DP master and the slave, which occurs once in every DP cycle. GTU is a modular device supporting up to 144 bytes of input data.

Modules define a block size of input and output data to be read by the master, starting from offset zero. During the network configuration session, modules with varying sizes of input data are provided in the GSD file.

EntelliGuard TU Trip Units: UL/ANSI Models DEH-4567B Battery Information

SECTION 10. BATTERY INFORMATION

The trip unit has a front pane-mounted battery. When the battery is present, the user scan view data on the LCD and read or program the trip unit via the keypads. The battery allows the user to display data, change set points and provide thermal memory.
During normal operation the trip unit is powered either from current flow in the circuit breaker’s internal current transformers or from an external DC supply. When neither of these sources is available it is still possible to review and modify settings or view events in the EntelliGuard TU using power from the internal battery. Pressing any keypad button will bring up the LCD display allowing full navigation of the trip unit’s menus. Note that only the LCD function is powered by the battery – communications, digital I/O and protection functions are not powered in this mode of operation.

The trip unit will automatically shut off after 20 sec when battery powered to maximize battery life.

Duracell CR2 is the replacement battery.

BATTERY FUNCTION

Pressing any key on the face of the trip unit powers the unit from its internal battery. Battery power is maintained for 20 sec after the last key is pressed.

This self-powered mode allows setting up the trip unit or viewing trip targets when the breaker is de-energized and external control power is unavailable.

All normal setup, meter, and status functions can be performed with battery power.

Other General Troubleshooting Issues

Nuisance tripping Review Pickup, Band and Slope settings. Coordination Study is optimal but remember EntelliGuard has Delay bands and slopes that can be much faster than MVT. Settings that are lower than application can support can create nuisance tripping. E.g. Transformer or Motor Magnetizing inrush can be up to 10 to 15X nominal and setpoints set to low enough pickup and delay may nuisance trip on this if not set appropriately.
Nuisance firing of Bell Alarm on PB2 Review settings of Bell Alarm LO (lockout) and Bell Alarm (alarm only). Consult settings instruction. Group 3 is for Overcurrent trip only (most used setting). Many units have had default setting of Group 15 where any trip condition such as shunt, UVR or Prot. Relay will fire the bell alarm. If Bell Alarm still nuisance fire with the correct setting, contact Post Sales Service (PSS).
Display will not come up with battery power and or line current
The internal battery power supply can be used at 10% or lower current and CT’s will power up the trip unit at 15% or greater. Between 10 and 15% the CT’s or the internal battery power supply may not power the display. A test kit or external battery pack tvpbp and tvpbpacc can be used as well as external 24VDC power. The backlight requires either 24V, external battery pack, test kit or nearly full CT power.
Nuisance trip when pressing keypad and under communication
Contact Post Sales Service 1-888-GE-RESOLVE, 1-800­GE-RESOLVE
RELT Instantaneous cannot be set If the trip unit does not have the required 24VDC control power, it cannot read RELT inputs and will not allow setting to be changed. You can change settings when powered with 24VDC, test kit or battery pack.
Confusion about GF CT vs. GF Sum GF CT is only for special situations where an external zero sequence detecting CT is used around all phases and wired to an EntelliGuard G breaker (not a neutral CT). Most applications are GF Sum (including use of a neutral CT and those without).
duty and the contacts are closed only during the GF Fault condition.
Breaker contact status reads incorrectly (e.g., on a
PB2 display reads Closed when breaker is Open)
Trip unit can only read correct status when trip unit if fully powered by either CT current of approximately. 80%, 24VDC, test kit or battery pack.
Batteries go dead prematurely (e.g., within few
months)
Excessive use of keypad (hours) can cause this. Otherwise if load current is constantly at 10 to 20% of CT rating, contact PSS.
GF nuisance tripping on EntelliGuard G breakers Verify there is not a GF sensing application issue such as incorrect neutral sensor polarity, incorrect bonding at neutral CT or downstream or related issues. Check current metering when breaker is OPEN, if currents do not read zero trip unit will need to be replaced-contact PSS to determine if warranty.
BIM trip If trip unit is installed into a breaker other than the one this was first installed in, this will occur. NEW trip units should not cause this when first installed into a breaker. If this occurs with a new trip unit that was not installed in a breaker, contact PSS as the breaker BIM module might be corrupt.
Software Revision 8.00.23 and greater: If a BIM read fails the trip unit will not trip the breaker, instead it will modify its internal configuration to match the AIC rating of the least capable breaker in the family. The trip unit will periodically read the BIM after that, and on a successful match the original settings will be restored. While the BIM error persists a BIM Err message will be displayed on the LCD.
Nuisance trip with NO EVENT information Verify there are no accessories and that settings are not too low in the presence of high inrush conditions at low CT current causing the trip and then contact PSS.
Settings cannot be changed to desired level Check in the SETUP Long time pickup screen that the LT pickup multiplied by the Rating plug equals the Pickup Amps displayed (e.g. 0.5 LTPU times a 2000A plug equals 1000A displayed on the bottom of LTPU screen.
