Page 13: Introduction
Through BESTCOMSPlus, all BE1-11m settings and logic can be retained in a file for printing or uploading to other BE1-11m protection systems. Oscillography and sequential events records can be retrieved from a BE1-11m, viewed, and printed.
Page 14 Three free-form fields (Device ID, Station ID, and User ID) can be used to enter information to identify the BE1-11m. These fields are used by many of the reporting functions to identify the BE1-11m reporting the information. Examples of BE1-11m identification field uses include motor name and motor number.
Page 15 NTP synchronizes the real-time clock to network time servers through the Ethernet port. BESTCOMSPlus is used to establish the priority of time reference sources available to the BE1-11m, IRIG-B, NTP, DNP, and RTC (real-time clock). The NTP address is set using BESTCOMSPlus.
Page 16 BESTlogicPlus. Alarms Extensive self-diagnostics will trigger a fatal relay trouble alarm if any of the BE1-11m core functions are compromised. Fatal relay trouble alarms are not programmable and are dedicated to the Alarm output (OUTA) and the front panel Relay Trouble LED. Additional relay trouble alarms and all other alarm functions are programmable for major or minor priority.
Page 17 BESTwave is included on the BE1-11 product CD. Sequence of Events Recorder A Sequence of Events Recorder (SER) records and time stamps all BE1-11m inputs and outputs as well as all alarm conditions monitored by the BE1-11m. Time stamp resolution is to the nearest half-cycle. I/O and Alarm reports can be extracted from the records as well as reports of events recorded during the time span associated with a specific fault report.
Page 18 Optionally, an SEF (sensitive earth fault) version of the separate ground CT is available. Note BE1-11m protection systems enabled for IEC-61850 communication (style Mxxxx5xxxxxxxx) do not allow voltage controlled or restrained overcurrent elements. Blocking a 51 with an Undervoltage (27) element may allow control pending application requirements.

Page 93: Phase Current Differential (87) Protection
The phase-current differential element compares the currents entering and leaving the protected motor. If a fault is detected, the BE1-11m initiates a trip signal to isolate the motor. This action limits damage to the motor and minimizes impact on the power system.
Page 94 If the target is enabled for the element, the BE1-11m will record a target when the Trip output becomes true. See the Fault Reporting chapter for more information about target reporting.

Page 96 Instantaneous Overcurrent (50) element provides flux-balancing protection. Figure 15-4. Flux-Balancing Connections If a BE1-11m is equipped with the differential option, an alternate method can be used to configure flux- balancing protection. In the Phase Differential (87) window of BESTCOMSPlus, set the mode to Flux Balance.
Page 97: Power (32) Protection
To clarify the difference between Three of Three and Total Power modes, assume that Two of Three mode has been selected and the pickup setting is 30 watts. Therefore, the BE1-11m picks up when two of the three phases have exceeded 30 watts. Alternately, if two phases are zero (0) watts and the third phase is 70 watts, the BE1-11m does not pickup because two of the phases have not exceeded the pickup threshold required for operation in Two of Three mode.
Page 98 In addition to exceeding the power pickup threshold, direction of power flow (forward or reverse) must match the directional setting for the 32 element to operate. In the BE1-11m, the forward and reverse directions are defined by the polarity voltage and current connections to the BE1-11m as shown in Figure 16-1.
Page 99 Element Blocking Fuse Loss The fuse loss (60FL) element of the BE1-11m can be used to block 32 protection when fuse loss or loss of potential is detected in a three-phase system. If the 60FL element trip logic is true and Block Power/Power Factor is enabled, all functions that use power measurements are blocked.

Page 315: Introduction To Testing
Because this is a numerical BE1-11m whose characteristics are defined by software, Basler Electric does not require the user to test each operational setting in the BE1-11m. Successful completion of the Acceptance Test verifies proper response of the protection system’s input and output circuits as well as its response to all external sensing input quantities (voltage, current, frequency).
Page 316 Sequence of Events Recorder (SER) Reports, and Oscillographic Records yield more detail. Each time a system disturbance occurs in or around this BE1-11m zone of protection, it is a test of the BE1-11m performance during the fault. If a questionable operation results in the need for troubleshooting, you have several ways in which to troubleshoot the BE1-11m, the installation, and overall application.
Page 317 Trouble LED on the front panel turns ON, all of the output relays are disabled, internal logic point ALMREL is set, and the BE1-11m is taken off line. For more information on self-test diagnostics and relay trouble alarms, see the Contact Inputs and Outputs chapter.

The answer to the question is yes and no. In general, once the fault goes away the output contacts open. The BE1-11m does offer an option to ensure that the contact will stay closed for at least 200 milliseconds. See the Contact Inputs and Outputs chapter for additional information on that function. Also, a Set Priority Latch in BESTlogic™Plus can keep the relay outputs closed as long as power is applied.

Page 490 T curves, refer to the Inverse Overcurrent (51) Protection chapter. Time Overcurrent Characteristic Curve Graphs The figures after the tables illustrate the characteristic curves of the BE1-11m. Table 82-2 cross- references each curve to existing electromechanical relay characteristics. Equivalent time dial settings were calculated at a value of five times pickup.
Page 491 User Tables Time Dial Setting Cross-Reference Although the time characteristic curve shapes have been optimized for each BE1-11m, time dial settings of Basler Electric protection systems are not identical to the settings of electromechanical induction disk overcurrent relays. Table 82-3 helps you convert the time dial settings of induction disk relays to the equivalent setting for Basler Electric protection systems.
Page 492 When using the 46 curve, the user should convert the continuous I rating data to actual secondary current at the BE1-11m. This value (plus some margin, if appropriate) should be entered as the pickup setting. For example, if a generator’s rated full-load current is 5 amperes, a pu setting of 0.5 A would allow 10% continuous I...
Page 493 When curve 46 is selected, the BE1-11m changes the range of the allowed time dial to 1 to 99 (instead of the time dial range of 0.1 to 9.9 for all the other curves). The user should enter the “K” factor of the generator into the time dial field.

Page 557 For conservative protection, choose 4 • 5%, which is 20 percent imbalance. A 10 second delay is appropriate because the heating is slow (motor mass is large). The pickup setting calculation is shown in Equation 84-8. BE1-11m Settings Calculation Examples...

Page 582 The unbalanced voltage feed to the motor should not exceed 5 percent. The BE1-11m must monitor and react quickly for a current unbalance condition. Because the BE1-11m uses negative-sequence current in the 49TC thermal model, additional unbalance (and single-phasing) protection can be added using the Average mode.
Page 583 If there is an increasing voltage unbalance in the power system (incorrect phase connections, stator turn- to-turn faults, or motor winding connections corroding or loose, for example), the BE1-11m can alarm so that you can take action before tripping the motor on unbalance current. Use the 50-4 element to alert operations and maintenance personnel to take corrective action.
