Cat. No(s): 0 026 54
KNX modular dimmer 2 x 300 W
1. USE
The KNX modular dimmer Cat No. 0 026 54 is used for controlling
dimming on two circuits up to 300 W per channel.
It is compatible with incandescent bulbs, high and low voltage halogen
lamps and dimmable LEDs.
The associated load (R, L or C type) is identified automatically, or
manually by the user.
To check that the wiring is correct, each channel can be controlled
locally on the controller by means of push-buttons and LEDs on the
front panel.
The device operating parameters can be configured with ETS and
modified using NFC technology via the Legrand Close Up app.
The main application program functions are as follows:
• Configuration of dimming speed
• Definition of min./max. dimming thresholds to ensure consistent
dimming
• Configuration of the scene control function (8 scenes max. per
channel)
• Definition of a hold threshold and a time delay
• Selection of the load state after a power failure
• Configuration of error message objects
• Configuration of time delay indicator objects
