Quantity of data and status information that can be collected is limited by the space available to mount discrete devices and the capability of SCADA terminals to collect and process data. BE1-DFPR relays are multi-phase, multi-function devices in economical, standard 19-inch rack units and require less space than the equivalent electromechanical overcurrent relays.
DFPR relays store minimum and maximum demand values. This information can be retrieved periodically to keep track of load peaks and growth for planning purposes. SPECIFICATIONS BE1-DFPR relays are available with the following features and capabilities. Accuracies of Measured Currents Refer to Table 1-1 for accuracies of front panel instrumentation measured currents.

CONTROLS AND INDICATORS LOCATION OF CONTROLS AND INDICATORS The BE1-DFPR, horizontal mount is shown in Figure 2-1, and the BE1-DFPR, vertical mount is shown in Figure 2-2. A description and an illustration of the controls and indicators for the Control Module, Contact Sense Module, and Magnetics Module is provided in the following paragraphs.
BE1-DFPR Controls and Indicators CONTROL MODULE (Figure 2-3) Function/Data One line, 12 character display to monitor function status and settings. Status/Targets Reset Resets targets in display window and the two electromechanical front panel targets (TRIP 1 and TRIP 2) mounted on the relay module assembly behind the contact sense front panel.

FUNCTIONAL DESCRIPTION GENERAL BE1-DFPR relays are multi-phase, multi-function, microprocessor based relays. A functional description is provided for each BE1-DFPR function and refers to the functional block diagram, Figure 3-1. BLOCK DIAGRAM ANALYSIS General External contact inputs (control inputs) are routed through an optional test panel module if the test panel module is present.
BE1-DFPR Functional Description Close Outputs Two isolated sets of close contacts are provided on terminals 3A, 4A and 11A, 12A. When a reclose occurs, one or both of the outputs close if selected using the RECLOSE LOGIC screens (3, 6, 9, J and M) under REVIEW/EDIT SETTINGS menu as described in publication 9 2315 00 991, Terminal Displays and Settings .
BE1-DFPR Functional Description RESET TARGETS RESET WATT-VAR HOURS ENABLE NORMAL SETTINGS ENABLE AUX1 SETTINGS ENABLE AUX2 SETTINGS ENABLE AUX3 SETTINGS ENABLE AUX4 SETTINGS These functions are selected from the PROGRAMMABLE INPUTS screen under REVIEW/EDIT SETTINGS menu as describe in publication 9 2315 00 991, Terminal Displays and Settings .
BE1-DFPR Functional Description Alarm Outputs Separate pairs of isolated contacts are provided for 5 alarm outputs. These outputs and the appropriate terminals (indicated in parenthesis) are as follows: Prog 1 (21-22), Prog (programmable). These alarm outputs may be programmed by the user to Prog 2 (23-24) operate for one or more conditions established during the setting up process.
BE1-DFPR Functional Description connectors on the front and rear panels. Connection to the front panel automatically disables the rear port. MODES OF OPERATION DFPR relays have two primary modes of operation. They are: Status mode Settings mode These modes are selected by momentarily pushing or rocking (either up or down) the front panel Status/Targets select or Settings select switches.

Only the normal settings group can be edited from the front panel settings mode. In addition to the normal operational settings for distribution circuit protection, the BE1-DFPR can program settings for additional tripping schemes. Each of these schemes is user definable in terms of pickup settings for elements, the operation of each tripping element, and the response of the reclosing section.

Figure 3-3. Typical Breaker Failure Sequence AUTOMATIC RECLOSING BE1-DFPR relays include a reclosing section that provides up to 4 reclosing attempts. CLOSE 1 and CLOSE 2 outputs operate in parallel and remain closed for a minimum of 200 milliseconds upon receipt of a CLOSE command.
BE1-DFPR Functional Description The number of reclosing attempts may be limited by setting any of the reclose time delays to zero. A reclosing attempt time delay set to zero forces the reclose logic to LOCKOUT and will not allow any further reclosing attempts.
CONTROL FUNCTIONS Supervisory Trip/Supervisory Close (Trip/Close) In addition to providing protection for the feeder, the BE1-DFPR is capable of accepting breaker TRIP and CLOSE commands from momentary contact closures of the SCADA system or breaker control switch and issuing the actual commands to the breaker.
BE1-DFPR Functional Description SYSTEM DIAGNOSTICS AND ALARM OUTPUTS Relay Trouble This NC contact will be energized after an initial power-up delay and remain energized (open) unless one of the following problems is detected within the relay: Power Supply failure (Relays may be supplied with an optional redundant power supply. Each power supply is capable of supplying the total requirements of the package.

BE1-DFPR Functional Description When you have completed a communications procedure, you may want a printed or file copy for later reference. You can use the following procedures to capture computer communications screen data when you are using either Windows or Procomm®.
INSTALLATION GENERAL When not shipped as part of a control or switchgear panel, BE1-DFPR relays are shipped in a sturdy carton to prevent damage during transit. Immediately upon receipt, check the model and style number against the requisition and packing list to see that they agree. Visually inspect for damage that may have occurred during shipment.
Typical DC control connections are shown in Figure 4-3. A typical Connection Diagram is shown in Figure 4-4. BE1-DFPR relay terminals as seen from the back of the relay are identified in Figure 4-5. All terminals are suitable for use with wire sizes of 12 AWG or smaller. Terminal strips mounted on the rear of the relay have 6-32 screws that accept wire sizes of 12 AWG and smaller or 0.312 inch wide rings and spade...
TESTING GENERAL A BE1-DFPR Test Simulator (shown in Figures 5-1 and 5-2) makes testing BE1-DFPR relays much easier. All contact sensing inputs and enable inputs are simulated by toggle switches that are easily accessable on the front panel. Appropriate LEDs provide BE1-DFPR relay functional indications. Additionally, the test procedures in this section use the Test Simulator switch and LED names.
