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 in the event of underload S1 - S2 bridged = relay energized in the event of underload 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. In the case of an error memory (no bridge over S1-S3), the error message remains until acknowledged or until the supply voltage is interrupted.,Operating voltage 230 V AC,Frequency range 2 to 200 Hz,Input / motor voltage 230 V AC / 400 V AC,Input / current min. 0.2 A / max. 10 A,Input / response value cosPhi 0 to 0.97, adjustable,Input / response time 1 to 100 s, adjustable,Output 1 changeover contact,Output / switching voltage max. 250 V AC,Output / continuous current max. 4 A,Output / switching frequency 1200 switching cycles/h,Display LED green, red,Dimensions W x H x D 22.5 x 75 x 100 mm,Weight 170 g,Operating temperature range 0 °C to +55 °C,Storage temperature range -20 °C up to +70 °C, protection class housing / terminals IP40 / IP20
