If you wish to change the method of controlling
the dimmer on the secondary side from push-
button (3) to 1–10 V (1), the driver must be reset.
What to do:
1. Turn off the primary power supply to the driver.
2. Short-circuit the 1–10 V input, switch on the
primary power supply for at least 5 seconds.
3. Switch off the primary power supply and
remove the short-circuit on the 1–10 V input.
4. The LED multidriver is now reset. Move
the jumper to J1.
5. Connect an external 1–10 V controller to
the driver.
Note:
When push-button dimming has been
activated the 1–10 V control is disabled.
Operating instructions
Dimming using the push-button switch, with
the jumper in position J2.
• On/off – short push of the button.
• Stepless dimming – long push of the button.
• Fine tuning – every long push changes
the direction of the adjustment compared to
the previous push.
Light level memory setting. The light level returns
to the level it was at when the light was turned off
(even after a power cut).
