METZ CONNECT MC CPW-E12 - Cosphi monitoring/CPW-E12

The cosPhi monitor is used to detect an underload. The response value and response time are adjustable. It can also be used in conjunction with a frequency converter (frequency 2 to 200 Hz). Monitoring is carried out by detecting the phase shift between current and voltage. This phase angle shifts with the load on a motor. Function settings via bridges S1 - S2 - S3: S1 - S2 open = relay released on underload, S1 - S2 bridged = relay energised on underload, S1 - S3 open = with fault memory, S1 - S3 bridged = without fault memory. The module can be unlocked remotely via a NO contact on S1 - S3. In the case of error memory (no bridge via S1-S3), the error message remains until acknowledged or until the supply voltage is interrupted. ...
