LMWVR-5-A 2507 XXXXX HS Code: 85364900 Country of Origin: UK Dims: to DIN 43880 W. 17.5mm INSTALLATION AND SETTING

  • BEFORE INSTALLATION, ISOLATE THE SUPPLY.
  • Connect the Auxiliary and Monitored Inputs as required. Setting the unit.
  • Set the “Nominal voltage” selector ➑ to the match that of the voltage being monitored on terminals B1 and B2.
  • Set the “Under %” ➎ and “Over %” ➐ trip levels as required. These are scaled as a % of the selected nominal voltage.
  • Set the “Delay” ➏ as required. Applying power.
  • Apply power and the green LED ➊ will illuminate. Both yellow LED’s will remain extinguished and the relay will energise. The red LED ➋ will also illuminate. Under voltage condition:
  • If the monitored voltage falls below the “Under %” trip level the yellow “<Un” LED ➌ will start flashing. The relay will de-energise and red LED extinguish after the delay period “t” has elapsed. The yellow LED will then remain illuminated to indicate an under voltage condition. The relay will re-energise/red LED illuminate (and yellow LED extinguish) when the voltage rises above the trip level plus the hysteresis. Over voltage condition:
  • If the monitored voltage rises above the “Over %” trip level the yellow “>Un” LED ➋ will start flashing. The relay will de-energise and red LED extinguish after the delay period “t” has elapsed. The yellow LED will then remain illuminated to indicate an over voltage condition. The relay will re-energise/red LED illuminate (and yellow LED extinguish) when the voltage falls below the trip level minus the hysteresis.
