LPPI-3-A 2303 HS Code: 85364900 Country of Origin: UK Dims: to DIN 43880 W. 17.5mm INSTALLATION AND SETTING

  • BEFORE INSTALLATION, ISOLATE THE SUPPLY.
  • Connect the unit as required. The Connection Diagram below shows a typical installation, whereby the supply is being monitored by the Phase Indicator. If a fault should occur (i.e. fuse blowing), the LED’s on the unit will indicate accordingly. Applying power.
  • Assuming all phases present and phase sequence correct the “ SEQ. ” ➊ LED will illuminate in green and “L1, L2 and L3 ” ➋ LED’s also illuminate (in green). Fault examples - Phase reversal
  • If two phases become reversed or power is applied with two phases already reversed, the “ SEQ .” LED will illuminate in red to denote a fault. Fault examples - Phase Loss
  • If during operation a phase is lost, the corresponding green LED for that phase will extinguish. Provided the other two phases are still connected, the LED’s for those phases will continue to illuminate.
  • The “ SEQ .” LED will change colour from green to red to denote a fault. This applies regardless of which phase is lost. Troubleshooting. The table below shows the status of the unit during a fault condition. Supply fault SEQ. LED L1 LED L2 LED L3 LED L1 Phase missing Red Off On On L2 Phase missing Red On Off On L3 Phase missing Red On On Off Phases reversed Red On On On Any 2 or more phases missing Off Off Off Off TECHNICAL SPECIFICATION Supply/monitoring voltage U (L1, L2, L3): 320 – 490V AC Frequency range: 48 – 63Hz Overvoltage category: III (IEC 60664) Rated impulse withstand voltage: 4kV (1.2/50 µ S) IEC 60664 Power consumption (max.): < 4VA Monitoring mode: Phase reversal and phase loss Phase present indication: Green LED x3 Phase sequence status indication: Bi-colour LED x1 Green = Sequence correct Red = Sequence incorrect Ambient temp: -20 to +60 °C Relative humidity: +95% max.
