    Target indicators may be reset with the manual reset lever. 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 five 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.

  • Page 15: Power Supply Status Outputs

    If the power supply voltage fails or falls below requirements, the power supply status output relay will deenergize, closing its contact. If the power supply status output is provided, then auxiliary output contacts are not available. BE1-50 Functional Description...
