AstroDIM

Kirjeldus

Astro-based mode

In this mode, the LED driver performs a dimming profile based on the daily power-on and power-off times.
The dimming schedule is adapted according to the length of the night. The Tuner4TRONIC® software calculates the annual average middle of the night based on the theoretical sunrise and sunset times, which are related to the location selected in the software. Based on this average middle of the night, five independent dimming
periods can be defined in the reference schedule. The minimum length of one dimming period has to be longer than the AstroDlM fade time. Valid time values can be set between 12:00 pm and 11:59 am. If less than five output levels need to be performed, two sequenced levels have to be set to the same value.
Note:
The maximum duration of one step is limited to ≤ 8 hours. The defined dimming profile is already performed after the second power-off/on cycle after programming.

Presence detection in AstroDIM mode

In the “AstroDIM + presence detection” dimming mode, it is possible to override the dimming profile of AstroDlM by shortening the 0 -10V interface with an external relay triggered by a sensor (e.g. motion sensor or presence sensor). If the 0 -10V interface is shortened, the output level is set to 100%.
Note:
The relay should be suitable for small currents (~1 mA for the 0 -10V interface) and also provide the sufficient
insulation to maintain the insulation level between the primary and secondary side of the LED driver.
