Indication of module operation.

Indicator Status Description
Power Power
Power not available
Activity Transferring data
No data transferring
Error No errors


The device blinks once every two seconds. The data has not been transferred via the CAN bus for at least 5 minutes.


One blinking in half a second. No power on the lamp.

Module installation and connection procedure

  1. Install the module in the switchboard on the DIN rail and fix it with the special latch on the module base.
  2. Connect the CAN connector.
  3. Connect the X1, X2 connectors.
  4. Configure the module using LT setup.
  5. Apply power to the load.
  6. Check all equipment for proper operation.

Module shut-off and deinstallation procedure

  1. Disconnect the power from the load.
  2. Disconnect the connectors X1, X2.
  3. Disconnect the CAN connector.
  4. Remove the module from the DIN rail, releasing the latch at the bottom of the module base.

HW Settings

Name Type, range SUBID Default Description
def integer 0-250 1-2 100 The default brightness level in case of a power reset (1..250). Example: def=250
min integer 0-100 1-2 0 Minimum dimming level, example: min=10
max integer 0-100 1-2 100 Maximum dimming level, example max=95
start integer 0-100 1-2 0 The Start function is used for lamps that lack the minimal voltage to get turned on. If the set value is lower than the start value, the lamp is turned on at the start value and them the light is dimmed down to the set level. Example: start=60
force integer 0-100 1-2 10 Time duration of the starting value (measured in milliseconds). Example: force=20
runtime integer 0-60000 1-2 1000 Runtime is the speed of changing the brightness from ‘min’ to ‘max’ (measured in milliseconds). Example: runtime=1000
protect integer 0;1 1-2 0 Overload Protect. 0(off); 1 (on), example: protect=0
mode string 98 disabled  Frequency of pulse-width modulation in Hz for item with direct current.

  • dc100 – 100Hz
  • dc200 – 200Hz
  • dc400 – 400Hz
  • dc800 – 800Hz

Example: mode='dc400'

dm char[2] 98 'gg' Each char is responsible for the type of a particular channel

  • 'g' – use like halogen dimer-lamp
  • 's' – Soft Switch, lamp, when on/off power is supplied/deenergised smoothly (500msec)
  • 'k' – Switch, lamp, when on/off power is supplied/deenergised immediately
  • 'l' – LED Function, dimmable LED lamps
  • ‘v’ – linear Function of dimming
  • '-' – Channel disabled
  • '+' – Regular channel
  • Example: dm='s-'
