For your safety

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Safe electrical installation must be carried out only by skilled professionals. Skilled professionals must prove profound knowledge in the following areas:

  • Connecting to installation networks
  • Connecting several electrical devices
  • Laying electric cables
  • Connection and setup of KNX networks
  • Connection and setup of DALI networks
  • Connection and setup of emergency lighting systems
  • Safety standards, local wiring rules and regulations
    Failure to follow these instructions will result in death or serious injury.

Getting to know the Gateway

The KNX DALI Gateway Basic REG-K/2/16/64 (referred to below as the gateway) connects the KNX bus to the DALI bus. Lights with DALI electronic ballasts can therefore be integrated into a complete KNX system in the form of a subsystem and  operated using  thewide range of KNX devices available.
The device converts switching and dimming commands of the connected KNX system into corresponding DALI telegrams or status information from the DALI bus into
KNX telegrams.
The gateway comes with two separated DALI channels (D1 and D2)
The electronic ballasts can be switched, dimmed or set to a defined value in 16 groups for each gateway.
Notes

  • Single Master Application Controller (EN 62386-103). The device may only be operated in DALI lines with electronic ballasts connected and not with other DALI control units within the line (no multi-master operation).

  • The power required for up to 64 connected electronic ballasts is supplied directly from the gateway. No additional DALI power supply is required, nor is this permissible.

  • The special interface for configuration of the DALI segment is designed as a DCA (Device Control App) for the ETS5. Note that, in addition to the product database
    (knxprod file), a corresponding ETS app (etsapp file) is also installed. Both files are available in the KNX online catalogue  and on the  manufacturer website.

  • DALI devices for single-battery emergency  lights of device type DT-1 can be read by thegateway and switched and operated via DALI telegrams if required. DALI commands for starting and reading test results are not supported.

Product features

  • 2 independent DALI channels

  • Addressing of 16 DALI groups per channel

  • Flexible DALI commissioning concept in ETS5

  • Coloured light control with the support of ballasts of device type 8

  • Coloured light control depending on ballast subtype:
    – Colour temperature (DT-8 subtype Tc)
    – XY colour (DT-8 subtype XY)
    – RGB (DT-8 subtype RGBWAF)
    – HSV (DT-8 subtype RGBWAF)
    – RGBW (DT-8 subtype RGBWAF)
    – DT-8 subtype PrimaryN is not supported

  • Support of timer programmes for control of groups by value and/or colour

  • Various operating modes for groups such as continuous operation, night mode, staircase mode

  • Integrated operating hours counter for each group, with alarm once the end of the service life has been reached

  • Individual fault detection with objects for each individual light/electronic allast

  •  Complex evaluation of faults at group/device level with fault number and fault rate calculation

  • Fault threshold monitoring with individually adjustable threshold values

  • Scene module for comprehensive programming of scenes

  • Quick exchange function for simple replacement of individual defective electronic ballasts

  • Manual operation of group and broadcast telegrams via operating buttons on the device

  • Signalling of fault states and statuses via LEDs on the device

Starting up the gateway
Several steps are necessary to start up the gateway fully:

  1. Wire the DALI segment
  2. Connect the gateway to DALI and KNX bus
  3. Connect the gateway to the mains voltage
  4. Load the ETS application programme (.knxprod) and install the ETS app (.etsapp)
  5. Configure the ETS parameters and objects
  6. Assign the ETS-DCA DALI groups
  7. Start up the ETS-DCA DALI
  8. ETS download of application

****For a precise description of the start-up procedure, read these operating instructions and the latest application description.
It is installed on a TH35 DIN rail acc. to EN 60715, with the bus connection made via a bus connecting terminal. Network and DALI cables are connected via screw terminals on the device.

Connections, displays and operating elements

The appliance connections as well as the programming button and programming LEDs required for KNX commissioning can only be accessed in the distribution board when
the cover is removed.
Manual mode buttons can be operated and indicator LEDs read with the distributor cover closed.Schneider Electric MTN6725 - fig

D. DALI output terminals: D1 (channel 1) and D2 (channel 2)
E. Operating buttons with a status LED (red) for each group (1-8 and 9-16) for manual mode (group operation/group status, broadcast and service functions)
F. Mains connection
G. Operating button with status LED (RGB) for activating manual mode
****Further information on operation, operating modes and troubleshooting can be found in the application description.

Mounting the Gateway

  1. Position the gateway on the DIN rail.

  2. Attach the connecting cable for the DALI bus to thelower left terminals.
    ****The DALI control cables can be routed in a 5-corecable together with the wires for conductingmains voltage (single basic insulation is sufficient) in accordance with EN60929. Ensure they are labelled clearly, however. A  maximum cable length of 300 m must not be exceeded  for the entire DALI installation of a  segment (recommended cross-section 1.5 mm 2 ).

  3. Connect the mains voltage.

  4. Connect KNX.

**** Double basic insulation must be used between the KNX installation and the mains voltage!
For this purpose, additionally insulate the wires of the KNX cable as far as the bus connecting terminal  usingthe enclosed shrink hose.

Once all connections are complete and the supply voltage has been switched on, the DALI line can be commissioned and programming carried out with the ETS.

Please refer to the application description in order to perform these operations.
