... Application Considerations BASIC CONSIDERATIONS At OMRON, we are constantly working to improve the quality and reliability of our products. Protective Relays, however, use semiconductors, which are prone to malfunction. Be sure to use Protective Relays within their rated values. Use the Protective Relays only in systems that are designed with redundancies, flame protection, countermeasures to prevent operation errors, and other countermeasures to prevent accidents involving human life or fires ...

... Trip Point C Generally, in open-phase detection, detecting a complete open- phase is sufficient. In such a case, set the open-phase switch to the “Low” position. If using the motor in an imbalanced condition causes problems, or when detecting internal open-phases of a delta-con- nected motor, set the switch to the “High” position. Depending on the motor’ ...
Page 17
Reverse-phase Detecting Circuit The current reverse-phase detecting method is employed for detect- ing reverse-phase as shown below. After the motor starts operating, the current phase becomes transiently unstable during T1 (approx. 0.1 s) and so reverse-phase detection is not performed ...
