LMCCR_10A-6-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 “Hyst. / Mode” selector ➐ to the required position depending whether under or over monitoring is required. Select either a suitable hysteresis setting of 2% or 10% or choose Latch if required.
  • Set the “Range” ➏ to the required position (depending on monitored input current to be monitored). Set the “Power Up Delay” according to whether start up currents are likely in the application.
  • Set the “Trip Level %” ➎ and “Delay” ➍ to suit the selected monitoring range and delay to tripping period. Applying power.
  • Apply power and the green LED ➊ will illuminate. If Under current mode is selected:
  • Relay energises / red LED ➌ illuminate if the current is above the set “Trip Level”. If the current falls below the “Trip Level”, yellow LED ➋ flashes for the set “Delay” then remains lit. Red LED extinguishes / relay de-energises. If Over current mode is selected:
  • Relay energises / red LED ➌ illuminate if the current is below the set “Trip Level”. If the current rises above the “Trip Level”, yellow LED ➋ flashes for the set “Delay” then remains lit. Red LED extinguishes / relay de-energises.
