    A third major factor to be considered in reclosing is supervisory control. Supervisory control allows the operator to maintain control of the system at all times. The BE1-79M has inputs available to bypass the instantaneous reclose attempt and to drive the relay to LOCKOUT inhibiting relay operation at any time.

  • Page 19: Functional Description

    SECTION 3 • FUNCTIONAL DESCRIPTION GENERAL The BE1-79M Multiple Shot Reclosing Relay is a microprocessor-based device, which responds to the state of external contacts. In responding, the Relay provides automatic reclosure once the circuit breaker has opened to de-energize the line. Refer to Section 1 for major factors to consider when establishing a reclosing philosophy.

    • Recognition Dropout - This function replaces the standard recognition dropout time of 17.5 milliseconds. The relay initiates a reclosing sequence if a 52b occurs within 200 milliseconds of an RI or PI. Figure 3-3 illustrates the recognition dropout timing relationship. BE1-79M Functional Description...

    ITE, the instantaneous trip enable output contacts are closed while the breaker is closed if instantaneous trip enable switch 1 is in the enable position. Microprocessor The BE1-79M uses an 8-bit, low power, CMOS microprocessor which performs all timing and decision- making functions. Program Monitor Operation of the microprocessor is monitored by the program monitor.

    Changer (Optional) Power Supply Basler Electric enhanced the power supply design for unit case relays. This new design created three, wide range power supplies that replace the four previous power supplies. Style number identifiers for these power supplies have not been changed so that customers may order the same style numbers that they ordered previously.

    These resistors are part of the internal circuitry, despite their external location. When using test plug, (Basler part number 10095), with these relays, compensating resistors must be added. For ease of use, Basler Electric has manufactured test plug adapters with internal compensating resistors. Table 8-1 provides the appropriate test plug adapter part number for each power supply type.
