Title:
【発明の名称】コンプレッサの状態をモニタするための電子コントロール
Document Type and Number:
Japanese Patent JP2837266
Kind Code:
B2
Abstract:
The compressor controller includes a timing circuit for timing-out a detected fault in a compressor. Upon the fault existing for longer than a predetermined time limit, the controller removes power from the compressor. If the fault is corrected within the predetermined time limit, even momentarily, the timing process is discontinued and the controller continues to monitor the status of the compressor. The controller also includes a delay timer for delaying the re-energizing of the compressor after an interruption or loss of power occurs. The delay prevents short cycling of the compressor. The controller further includes a status display for indicating compressor functions, connections to an alarm which is initiated in the event of compressor failure, a switch for initiating a self test of the controller, and circuitry for a field applied current sensing relay.
