LBVR_A-4-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 unit as required taking note of the polarity of the connections. Terminal A1 is the positive connection and A2 the negative. Setting the unit.
  • Set the Under voltage “Trip Level (V)” ➍ adjustment to the voltage required.
  • Set the “Delay (t)” ➌ to minimum. Applying power.
  • Apply power and the green “Power supply” ➊ and red “Relay” ➋ LED’s will illuminate, the relay will energise and contacts 15 and 18 will close. Refer to the troubleshooting table if the unit fails to operate correctly.
  • If the supply voltage drops below the trip level setting, the green LED will start to flash. The relay will then de-energise (contacts 15 and 18 open) after the delay period “t” and the red LED will extinguish. The green LED will then remain permanently lit.
  • When the voltage increases above the trip level + hysteresis, then relay will re-energise and red LED illuminate. Troubleshooting. The table below shows the status of the unit during a fault condition. Supply fault Green LED Red LED Relay No supply Off Off De-energised Under voltage condition (during timing) Flashing On Energised for set delay (t) Under voltage condition (after timing) On Off De-en ergised TECHNICAL SPECIFICATION Supply/monitoring voltage U (A1, A2): 12 – 24V DC Supply variation: 75 – 125% U Power consumption (max.): 3W Monitoring mode: Under voltage Trip level: 9 – 28V DC Hysteresis: ≈ 5% of trip level (factory set) Setting accuracy: ± 10% Repeat accuracy: ± 0.5% at constant conditions Response time: ≈ 100mS Time delay (t): 0 – 30 Sec. ( ± 5%) Note: actual delay (t) = adjustable delay + response time Power on delay (Td): ≈ 1 sec.
