INTRODUCTION & PHYSICAL DESCRIPTION Power Supply Board Micro Panel ContentsSystem Switches 1 Internal Clock & Memory Backup Battery4T Supplies 24VAC power to the 2ACE Motor Protector Modules 2T This 75VA transformer supplies the 24VAC to the power supply boardRelay Output Boards Always review the data in the history buffer when faults occur. Since the Micro attempts to restart 2 more times and fails to restart with the M1-M2 contacts open, the Micro will record the last 2 faults of Low Curr/MP/ HP. Hence, the third 3rd history buffer will show data related to the true cause.
