Description
The cosPhi monitor is used for detecting underload. The response value and the response time can be adjusted. It can also be used in combination with a frequency converter (frequency: 2 to 200 Hz). Monitoring is accomplished by recognizing the phase shift between current and voltage. This phase angle varies depending on the motor load. The functions can be adjusted by means of bridges S1 - S2 - S3: S1 - S2 open = relay deactivated with underload, S1 - S2 bridged = relay activated with underload, S1 - S3 open = with fault memory, S1 - S3 bridged = without fault memory. The module can be unblocked remotely by means of a closing contact on S1 - S3. If there is a fault memory (no bridge over S1-S3), the fault message is active until it is acknowledged or the supply voltage is interrupted.
