Testing for DALI or DALI-2 compliance

Test equipment

Testing for DALI-2 and DALI version-1 compliance is carried out using ProbitLab test equipment, together with ProbitBench software. Both ProbitLab and ProbitBench are developed, owned and distributed by Lichtvision Engineering.

DiiA members are supplied with software Test Sequences that enable compliance testing. These test sequences are plugins for ProbitBench.

There are two different versions of the testing hardware: ProbitLab (no longer available) and ProbitLab2. 

Equipment Capability
ProbitLab ProbitLab can test DALI version-1 and DALI-2 control gear, provided they do NOT have an integrated bus power supply.
ProbitLab2 In addition to the above, ProbitLab2 can test DALI-2 control devices (e.g. sensors, application controllers etc), standalone bus power supplies, and devices with integrated bus power supplies.

Additional test equipment

Various other equipment is required, depending on the types of products to be tested. This includes:

  • Voltmeter and ammeter
  • Light meter
  • Digital storage oscilloscope
  • Fast light sensor (where fast light measurements are required)

It is recommended to use a light meter with a suitable USB interface, allowing automation of many of the measurements. The Extech SDL400 with Extech USB interface cable is currently supported.

For tests requiring fast light measurements, a photodiode such as TSL250R, or a detector using a photodiode such as the ThorLabs DET10A2, are suitable.

DALI Test Houses

Member companies can carry out the required tests for each product, or they can use the services of DALI test houses that are accredited by the DALI Alliance (DiiA).

Test sequences (software)

Test-sequence software for DALI-2 and DALI version-1 testing is developed by DiiA’s Technical & Certification Work Group (T&C WG), and supplied to DiiA members.

Test sequences for DALI-2 testing are based on the DALI-2 Test Specifications, which are in turn derived from either the multi-Part IEC 62386 standard or from new DiiA specifications.

To achieve DALI-2 certification, a product must show compliance with each specification (Part) that is implemented.

The DALI-2 certification program will be expanded through the development and release of new test sequences, according to the priorities determined by DiiA members.
