  • Page 5: Section 1 • General Information

    SECTION 1 • GENERAL INFORMATION GENERAL The BE1-49 Temperature Relay is a solid state device that monitors the temperature of a remotely located resistive temperature detector (RTD), and provides signals to the protective scheme when the sensed temperature goes above or below predetermined limits. A variety of output options provide a selection of latching or non-latching types of normally open or closed contacts.

    Figure 3-1. Functional Block Diagram 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 six 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.

    Refer to Figure 1-1 for a list of all of the available output options. Target Indicator An optional target indicator on the front panel is tripped and magnetically latched when the upper temperature limit is exceeded. It may be reset manually after the upper temperature limit output is de-energized. BE1-49 Functional Description...

  • Page 14: Section 4 • Installation

    If there is evident damage, immediately file a claim with the carrier and notify the Regional Sales Office, or contact Customer Service at Basler Electric, Highland, Illinois. In the event the relay is not to be installed immediately, store the relay in its original shipping carton in a moisture and dust free environment.

  • Page 15: Adjustments

    The relay has been calibrated at the factory and it is strongly recommended that the calibration adjustments not be disturbed. If, however, relay pickup accuracy is suspect for any reason, remove the relay from service and check the temperature settings using the procedures given in Section 5 of this manual.

  • Page 31: Section 6 • Maintenance

    SECTION 6 • MAINTENANCE GENERAL Basler relays are static devices which require no preventive maintenance other than a periodic operational check. The operational test procedure of Section 5 provides an adequate check to verify proper operation of the relay. Most components are on conformally coated PC boards. In-house replacement of individual components may be difficult and should not be attempted unless appropriate equipment and qualified personnel are available.

  • Page 32: Section 7 • Manual Change Information

    1. Corrected Style Chart by changing power supply type X from “230 Vac” to “240 Vac”. Added new power supply information to Section 3 in Power Supply paragraph starting with “Basler Electric enhanced the power supply design...”. Added new dimension figures to include all options available (S1 Single- Ended and Double-Ended, and both mounting positions).
