LOCAL DIMMING CONTROL
This function is to LOCALLY DIM THE LED INTENSITY from 0 to 100% (Product is
delivered with default setting of the Dimmer at 0)
he right knob is doing the dimming action and it goes with a fine tuning in normal
condition, or a fast dimming when rotating KNOB 2 while keeping KNOB 1 pressed
in.
When the DISPLAY is in STAND BY Mode, please rotate KNOB 2
to act on the LIGHT INTENSITY Dimming…Clock Wise to
increase the level and Counter Clock Wise to decrease it. Fine
control:
For faster Dimming Control keep KNOB 1 pressed
and rotate KNOB 2:
1 full TURN of the KNOB 2 = 40% Dimming
Variation
LOCAL CORRELATED COLOR TEMPERATURE CONTROL
This function is to LOCALLY ADJUST the CORRELATED COLOR
TEMPERATURE from 2.750°K to 6.900°K (Product is delivered
with default setting of the CCT at 2750°K)
The rotation of KNOB 1 will determine CCT increments according
to the following table (STEP MODE)
If a continuous CCT Adjustment is required (LINEAR MODE) it is
necessary to operate through a DMX Console: please see DMX
parameters above
LOCAL OR REMOTE CONTROL SETTINGS
The LED Fresnel has the facility to block the LOCAL DIMMING and CCT SETTINGS and
maintain it when the POWER is turned off and than on again.
This allows for the LIGHT to be TUNED and FOCUSED locally and its dimming plus CCT
level can be blocked, so that for instance a system lighting a SET can be operated by a
remote switch or simple brakers by TURNING POWER ON.
The machine is set to Auto save OFF as default: in this condition the Fixture can be
controlled locally until a DMX device is connected to it. Once the Console will be acting it
will take priority over any local control.
To turn the Auto sve ON please follow these instructions:
- rotate KNOB 2 and select Auto save OFF
- press KNOB 2 to highlight the status of Auto save, in this case OFF
- rotate KNOB 2 to turn the status of Auto save to ON and press it
- leave the settings in this condition; the light will ignore any DMX Control. In this mode
any local dimming setting will be maintained and will be automatically recalled after power
off, when turnig the power on again.
CHANNEL SETTING (RESOLUTION & FUNCTION)
This function is to SET THE DIMMING RESOLUTION either at 8 bits or at 16 bits.
Select DMX resol by rotating and pushing KNOB2, the following choices are available:
- 8 bits resolution (the display will show 8 bit). The fixture utilizes 1 DMX Circuit for the
Light Dimming, which is the BASE CIRCUIT set in the ADDRESS.
- 16 bits: 16 bits resolution (the disply will show 16 bit and this is the default setting).
The fixture utilizes 2 DMX Circuits:
The Base Circuit set in the address is the Coarse Dimming, the second Circuit (Base +1)
is the Fine Dimming.
Of course the benefit of the 16 bits function the corresponding circuits on the DMX
Lighting Board shall also beset at 16 bits.
The DMX channels Base +2 and Base +3 are dedicated to the CCT Variation Control as
described previously.
