DW-DALI.C Module Installation Manual describes the procedure for its installation, assembly, operation and setting. While working with the module, you must strictly comply with all the requirements set out in this manual. Failure to comply may result in damage to the device, its failure, electric shock, fire and other fallout.


  • Automatic line scanning for new devices
  • Built-in bus power injection
  • Dali device configuration

CAUTION! All work related to the installation, connection, setting up, service and support must be carried out by qualified personnel with sufficient skills and experience in working with electrical equipment. To avoid the risk of fire, electric shock, damage to the system and/or personal injury, the system installation and assembly must be performed in accordance with the instructions listed below:

  • all connectivity work must be carried out with the power turned OFF;
  • use appropriate tools and personal protection against electric shock;
  • do not use damaged cables, wires and connectors;
  • avoid folding the cables and wires;
  • do not apply excessive force to the wires by kinking or pressing them too hard: the inner conductors of the cables and wires may get stripped or damaged;
  • do not use the power socket with poor contacts to connect;
  • do not exceed the load limit parameters specified in the manual;
  • the supply conductors wire section is subject to the specifications for current density limit, insulation type and wire material. Light section can result in cable overheating and fire.

When the power is on, NEVER:

  • connect/disconnect the connectors;
  • open modules and sensors.

Module installation and assembly

Before connecting the module, you must determine the module installation place. Note: The module must be installed near 24V power supply.

Module installation and connection procedure

CAUTION! You must precisely follow the recommendations listed in the «Safety Requirements» section of this manual.

  1. Install the module in the switchboard on the DIN-rail and secure it with special latches available on the module base.
  2. Connect the CAN-bus (4).
  3. Connect the DALI-bus (1).
  4. Connect the DALI power connector (2).
  5. Energise the module power supply (24 V).

Module shutoff and disassembly procedure

  1. isconnect the power connector (2).
  2. Disconnect the DALI connector (1).
  3. Disconnect the connector of CAN-bus (4).
  4. Demount the module from the DIN-rail, releasing the latch, available at the module base.

Hardware setup

To configure and control DW-DALI module, you must install Larnitech software on your smartphone or t, which is available in App Store and Play Market. After installation, follow the System Setup Instructions.

Fault diagnostics and handling

The following are some possible faults and ways of fault handling. If you have any difficulty, or face the fault undeclared here, please contact the Technical Support: http://www.larnitech.com/support/ or support@larnitech.com. There are also some tips in the FAQ section at our website http://www.larnitech.com/faq/

System Setup Instruction

Each DALI bus can use 40 DALI devices. Together DALI buses for one DW-DALI.C can use 64 DALI devices. Address DALI device must be from 1 to 63. To add DALI devices to DALI bus, add «hw» to tag with SubID 98, hw=”bus1=’1,2,3,…’ bus2=’1,2,3,…’ “:

  1. bus1 — first DALI bus data;
  2. bus2 — second DALI bus data;
  3. 1,2,3 — address DALI devices.

HW Settings

Name Type, range SUBID Default Description
def string 'ON' certain SubID 'OFF' def is the element status is set after restart (only for Scenes).


def integer 0…250
integer -0…-250
certain SubID 100 The default brightness level in case of a power reset (0..250). Negative value will turned on the element.Example:


def string 'last' certain SubID 'off' Set last saved state of the element in case of a power reset. The element save his state after stay unchanged for 10 minutes.


dmin integer (0…254) certain SubID 0 minimum dimming level, 0..254; only for Groups

Example: hw="dmin=30"

dmax integer (0…254) certain SubID 250 maximum dimming level, 0..254; only for Groups

Example: hw="dmax=80"

dtype 6 or 8 certain SubID - Force mode to DT6 or DT8

Example: hw="dtype=6"

dt8features - certain SubID -
  • 0 - disable dt8 features
  • 'cc' - Use Color coordinate
  • 'tc' - Use Temperature color
  • 'primary6' - 6 channel dt8 mode
  • 'rgb6' - 6 channel RGB mode

Example: hw="dt8features='cc'"
