The cosPhi monitor is used to detect 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 de-energized when underload is present S1 - S2 bridged = relay energized when underload is present S1 - S3 open = with error memory S1 - S3 bridged = without error memory The module can be remotely unlocked using a normally open contact on S1 - S3. When there is an error memory (no bridge across S1-S3), the error message remains until it is acknowledged or until the supply voltage is interrupted.
