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 turning the power on again.
