    The BE1-79S Reclosing Relay will provide a single reclosure signal following a trip as an attempt in restoring power and minimizing system disturbances.

  • Page 6: Model And Style Number

    Test points and circuit components are accessible by removal of the individual printed circuit boards from the relay cradle and using an extender board (Basler part number 9 1129 30 101) to test or troubleshoot. An available test plug (Basler part number 10095) permits the relay to be tested in place without disturbing external control circuit wiring.

  • Page 38: Section 6 • Maintenance

    If the relay fails to function, and factory repair is desired, contact the Customer Service Department of the Power Systems Group, Basler Electric, for a return authorization number prior to shipping. Due to the fact that most components are on conformally coated printed circuit boards, in-house replacement of individual components may be difficult and should not be attempted unless appropriate equipment and adequately trained personnel are available.

  • Page 39: Section 7 • Manual Change Information

    Added Option 2-D when Option 2-S is referred to in the manual. Added new power supply information to Specifications and Section 3 starting with “Basler Electric enhanced the power supply design...” Corrected Figure 2-1 and Figure 4-9 by making 52b a NC output.
