The cosPhi monitor is used to detect an underload. The response value and the response time can be set. It can also be used in conjunction with a frequency converter (frequency 2 to 200 Hz). The monitoring is done by detecting the phase shift between current and voltage. This phase angle shifts with the load of a motor. Settings of the functions via bridges S1 - S2 - S3: S1 - S2 open = in case of low-load relay has fallen back, S1 - S2 bridged = in case of low-load relay energized, S1 - S3 open = with fault memory, S1 - S3 bridged = without fault memory. By means of a closer on S1 - S3 the module can be unlocked remotely. In the event of a fault memory (no bridge over S1-S3), the error message remains until the acknowledgment or until the supply voltage is interrupted.This text is machine translated.
