The Honeywell 10310/2/1 Earth Leakage Detector (ELD) is designed for 24 V DC systems to monitor earth leakage, ensuring operational safety and reliability. It includes features for manual testing, earth connection monitoring, and fault detection.

Features and Operation

  • Compatible Systems:
    • 24 V DC, 48 V DC, 60 V DC, or 110 V DC systems.
  • Modes of Operation:
    • Continuous Monitoring: Switch 1 in the ‘DC’ position.
    • Interrupting Connection:
      • At 1 Hz (Switch 1 in the ‘1 Hz’ position).
      • At 0.25 Hz (Switch 1 in the ‘1/4 Hz’ position).
  • LED Indicator: Green ‘MODE’ LED flashes at selected frequency.
  • Earth Fault Detection:
    • Earth faults trigger the flip-flop, de-energizing the relay.
    • Fault reset options:
      • Manually (Switch 2 to ‘RESET’).
      • High-level signal at Rst24 or Rst110 inputs.
  • Self-Test Function:
    • A 1.5 kΩ resistor connected between 0 V and earth can test the ELD.
    • Earth connection test via internal 1.5 kΩ resistor with Earth2 pin connection (Switch 2 in ‘TEST’ position).
