Overview:

DLIF RD is an emergency automatic rescue device (that continuously monitors the elevator mains supply and, upon power failure or phase loss, powers the elevator to move in light‑load direction to the nearest floor at a defined rescue speed, then opens the doors to release passengers. The ARD‑C platform offers redundant protections, smart battery management, CAN communication with controllers, and maintenance/test modes for quick verification. It supports three‑phase 380 V five‑wire, three‑phase 220 V four‑wire, and single‑phase 220 V inputs, with selectable 220 V / 380 V rescue output. Battery packs are three 12 V batteries in series with capacities selected by model.

Features & Benefits

Features & Benefits

  • Automatic rescue on power failure/phase loss: Moves car to nearest floor at emergency speed, opens door, and hands back to mains when restored.
  • Multiple input systems: 3Ø 380 VAC (±15%), 3Ø 220 VAC (−20%+15%), 1Ø 220 VAC (−20%+15%).
  • Selectable rescue voltage: 220 V or 380 V via parameter (A0‑03).
  • Rich protection suite: Battery discharge overcurrent, inverter output overcurrent, DC bus overvoltage, battery undervoltage, battery retirement monitoring.
  • Commissioning‑friendly: LED digital tube display, rescue time/response parameterization, maintenance & test modes, forced activation.
  • Smart battery management: Guidance to replace every 2 years; charge/discharge every 3–6 months for longevity.
  • Controller integration: CAN terminals provided; “rescue complete,” “fault,” and “emergency state” relay outputs for cabinet logic.
  • Flexible installation: Backplate or floor‑standing; IP20 enclosure.
