Explanation of Each MENU FUNCTION
DMX ADDRESS
This Function is to SET the DMX address from 1to 512 (Product is delivered with default
settingof the DMX address at 1)
Once the C001 is displayed, act on the "button to increase the address to the desired
value.
Temporary push will increment the value by 1, if the button is kept pushed the increment on
numbers is getting fast.
Once the desired Address number is accomplished press X(“ENTER”) to make it active
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).
The intensity goes in increments of 1/100% so the display will show 000% with the dimmer
at 0% and FULL with the dimmer at 100%.
Temporary push will increment the value by 1/100, if the button is kept pushed the
increment on numbers is getting fast.
Once the desired Lighting Level is accomplished and it is wanted to leave that level and go
to other functions of the MENU, press “ENTER”.
LOCAL OR REMOTE CONTROL SETTINGS
The LED Fresnel has the facility to block the LOCAL DIMMING SETTING and maintain it
when the POWER is turned first OFF and than ON again.
This allows for the LIGHT to be TUNED and FOCUSED locally and its dimming 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 relevant menu to access this function is CTRL, to enter in this menu press X(“ENTER”), it
is than possible to select either DMX or AUTO by acting on the "or #button and than
press X(“ENTER”) again. The machine is set to DMX as default.
•In DMX mode: the Fixture accepts DMX control….if in this mode the local DIMMING
CONTROL is SET to a level the Light behaviour will follow the HTP (Highest Takes
Precedence) modality, in other words it will keep the local DIMMING setting until the
DMX level of the specific channel will be higher, from that level onwards the DMX
level will take precedence. In this condition if the DMX connection is removed, the
light will keep the last level….until power is ON. It will reset and Start at 0after Power
OFF and ON again.
In AUTO mode: 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 turning the power on again.

Explanation of Each MENU FUNCTION
TEMPERATURE
This function Displays in real time the LED BAR Case temperature in °C.
When pressing Enter again you exit from the temperature display.
The steady state TEMPERATURE of the LED BAR reaches approx. 55°C after many hours of
continuous operation with an ambient temperature of 25-30°C.
The Thermal Handling of the LED is Automatically handled by the local electronics and the
LED will operate until the LED BAR temperature reaches 80°C, that anyway is still way within
the prescribed maximum nominal prescribed by the LED BAR manufacturer that is 105°C.
In case the LED BAR temperature reaches 80°C the unit will automatically turn off.
Even in extreme Ambient temperature conditions the LED BAR shall never reach the 80°C
limit.
The above protection threshold is there to protect the LED BAR from stressed working
conditions in case some other failures or specially critical working conditions are causing an
over-temperature.
CHANNEL SETTING (RESOLUTION & FUNCTION)
This Function is to set the DIMMING RESOLUTION either at 8 bits or at 16 bits.
Once CHAN is displayed, act on the "or #buttons to scroll through the following
choises:
•8D: 8 bits resolution (the display will show 8D and this is the default setting).
The Fixture utilises 1 DMX Circuit for the Light Dimming, which is the
BASE CIRCUIT set in the ADDRESS.
•8DS: NOT ACTIVE (for future use):
The foreseen function for this setting is: 8 bits resolution and STROBE (the display will show 8DS). The
Fixture will utilise 2 DMX Circuits,
the BASE CIRCUIT set in the ADDRESS will be the LIGHT DIMMING
and the second circuit (BASE +1) will be the STROBE
•16D: 16 bits resolution (the display will show 16D).
The Fixture utilises 2 DMX Circuits,
the BASE CIRCUIT set in the ADDRESS is the Coarse Dimming,
the second Circuit (BASE +1) is the Fine Dimming.
•16DS: NOT ACTIVE (for future use):
The foreseen function for this setting is: 16 bits resolution and STROBE (the display will show 16DS).
The Fixture will utilise 3 DMX Circuits,
the BASE CIRCUIT set in the ADDRESS will be the Coarse Dimming,
the second Circuit (BASE + 1) will be the Fine Dimming.
the third CIRCUIT (BASE + 2) will be the STROBE
Of course the 16 bits function is useful if the corresponding circuits on the DMX LIGHTING
BOARD are also set at 16 bits.
WARNING: if the LED FRESNEL is set at 16 bits, but more units are having a consecutive
unitary address (for instance first fixture set at Address 1, second fixture set at Address 2 and
so forth, the DMX Channel controlling the Coarse Dimming of the second unit, will also
control the fine dimming of the first unit. In this case it is recommended that all fixtures are
set to 8 bits resolution).
DMX LEVEL
It Shows the DMX Input level on percentage (0-99% and FULL) received effectively from the
Fixture.
