Overview
EN 62386-101:2014/A1:2018 is the CLC/CENELEC adoption of IEC 62386-101:2014 Amendment 1 for the Digital Addressable Lighting Interface (DALI) - Part 101: General requirements for system components. Published August–November 2018, this amendment (version 2.01) updates system-level requirements for DALI system components, adds explicit support for DC supplies, and clarifies timing, electrical and operational behaviour for bus-powered and externally powered devices.
Key topics and technical requirements
- Scope and versioning
- Current version identified as 2.01; amendment aligns EN and IEC texts.
- System architecture
- Defines required system components (minimum quantities): bus power supply (≥1), application controller (≥1), control gear (≥0) and input devices (≥0).
- Electrical ratings
- Nominal system voltage typical ≈ 20.5 V; absolute maximum 22.5 V; minimum 0 V.
- Signal levels: high level ≥ 9.5 V, threshold region around 6.5–9.5 V, low level ≤ 6.5 V.
- Current limits: bus-powered device maximum consumption (documented) - example max sink/transient values updated (e.g., bus-powered max ~250 mA when not transmitting).
- Devices must be polarity insensitive or supplies must withstand reverse voltages.
- Bus power and interruptions
- Defines classes of interruption (short, bus power down, system failure) with timing windows and required device behaviour during power cycles.
- Frame handling and timing
- Clear state model: bits received → stop condition → frame received/rejected → frame accepted/ignored → command accepted/ignored → command executed/discarded.
- Precise receiver and multi‑master bit timing and stop condition values updated (e.g., stop condition ≈ 2 450 µs), settling windows (e.g., 13.4 ms for backward-frame detection) and handling of backward frames and timing violations.
- Interoperability constraints
- Bus units restricted to transmit/receive only allowed frame types (except proprietary forward frames).
- Test and robustness guidance
- Requirements for bus supplies to withstand ringing, device current draw limits during power-up/down, and frame timing rejection rules.
Applications and users
This standard is essential for:
- Lighting manufacturers designing DALI control gear and bus units
- System integrators and specifiers ensuring interoperability and compliance
- Test labs and certifiers performing electrical, timing and functional conformance tests
- Installers and facility managers who need predictable behaviour for power interruptions, device addressing and multi-master systems
Practical uses include device design validation, interoperability testing, system-level specification and compliance checks for digital lighting networks.
Related standards
- IEC/EN 62386-102 (General requirements - Control gear)
- IEC/EN 62386-103 (General requirements - Control devices)
- Other IEC 62386 2xx/3xx parts (particular requirements for control gear and control devices)
- Cross-references to IEC 61347 noted in the bibliography handling
