7 Installation

The module can be snapped onto all 35 mm DIN rails according to EN 60715. An integrated wide-range power supply unit enables the connection of a supply voltage in the range from 24 V AC/DC to 240 V AC/DC. WARNING: Risk of electric shock Never carry out work when voltage is present.

10 Function

If an error is present when the monitoring module is activated, output relay "R" remains dropped out and the LED for the corresponding threshold value lights up. For all functions the "MIN" and "MAX" LEDs flash alternately if the minimum value selected is greater than the maximum value. The "FUNCTION" rotary switch is used to set the desired function: – O = Overload monitoring (OVER) – OL = Overload monitoring with error memory (OVER + LATCH) – U = Underload monitoring (UNDER) – UL = Underload monitoring with error memory (UNDER + LATCH) – W = Monitoring of the area between thresholds MIN and MAX (window function) (WIN) – WL = Monitoring of the area between thresholds MIN and MAX (window function) with error memory (WIN + LATCH)

102914_en_02 PHOENIX CONTACT 7 U LED U/t LED MAX LED MIN OL R Max Min OVER+LATCH LED REL, START DELAY DELAY START <DELAY Overload Monitoring (OVER and OVER + LATCH) If the measured power factor exceeds the value set at the "MAX" controller, the set response delay (DELAY) starts (red "MAX" LED flashes). After the delay time has elapsed (red "MAX" LED is ON), output relay "R" drops out (yellow "REL" LED is OFF). If the measured power factor falls below the value set at the "MIN" controller (red "MAX" LED is OFF), output relay "R" picks up again (yellow "REL" LED is ON). If the error memory has been activated (OVER + LATCH) and the measured power factor has exceeded the value set at the "MAX" controller for longer than the set response delay, output relay "R" does not pick up if the power factor falls below the value set at the "MIN" controller. Once the error has been reset (supply voltage interrupted, e.g., using an external button), output relay "R" picks up when the supply voltage is applied again and the measuring cycle starts again once the set starting override (START) has elapsed. U LED U/t LED MAX LED MIN UL R Max Min UNDER+LATCH LED REL, START DELAY DELAY START <DELAY Underload Monitoring (UNDER and UNDER + LATCH) If the measured power factor falls below the value set at the "MIN" controller, the set response delay (DELAY) starts (red "MIN" LED flashes). After the delay time has elapsed (red "MIN" LED is ON), output relay "R" drops out (yellow "REL" LED is OFF). If the measured power factor exceeds the value set at the "MAX" controller, output relay "R" picks up again (yellow "REL" LED is ON). If the error memory has been activated (UNDER + LATCH) and the measured power factor has fallen below the value set at the "MIN" controller for longer than the set response delay, output relay "R" does not pick up if the power factor exceeds the value set at the "MAX" controller. Once the error has been reset (supply voltage interrupted, e.g., using an external button), output relay "R" picks up when the supply voltage is applied again and the measuring cycle starts again once the set starting override (START) has elapsed. U LED U/t LED MAX LED MIN WL R Max Min WIN+LATCH LED REL, START DELAY DELAY <DELAY Window Function (WIN) Output relay "R" picks up (yellow "REL" LED is ON) if the measured power factor exceeds the value set at the "MIN" controller. If the measured power factor exceeds the value set at the "MAX" controller, the set response delay (DELAY) starts (red "MAX" LED flashes). After the delay time has elapsed (red "MAX" LED is ON), output relay "R" drops out (yellow "REL" LED is OFF). The output relay picks up again (yellow "REL" LED is ON) if the measured power factor falls below the maximum value again (red "MAX" LED is OFF). If the measured power factor falls below the value set at the "MIN" controller, the set response delay (DELAY) starts (red "MIN" LED flashes). After the delay time has elapsed (red "MIN" LED is ON), output relay "R" drops out (yellow "REL" LED is OFF).

Output relay "R" then picks up when the supply voltage is applied again and the measuring cycle starts again once the set starting override (START) has elapsed. U LED U/t LED MAX LED MIN LED I=0 R Max Min LED REL, START START <DELAY Detecting Switched Off Loads If the current flow between L1i and L1k is interrupted (yellow "I=0" LED is ON) and no stored errors are present, output relay "R" picks up or remains picked up (yellow "REL" LED is ON). When the current flow is present again, the measuring cycle starts again once the set starting override (START) has elapsed.
