Fx400 Series
CLO, typical user cases
To linearly dim the projectors and / or using the same dim value on all projectors in a multi-channel
configuration when e.g. going from a day scene to a night scene.
8.6.4.2 Example: CLO scale with one projector
Example: CLO scale with one projector
•
Light output: 5000lm.
•
Adjust the light output from the projector to 80%.
-
The projector now has a maximum light output of 4000 lm
•
Enable CLO scale
•
Light output at different CLO scale settings
-
100: 4000 lm
-
75: 3750 lm
-
50: 2000 lm
8.6.4.3 Example: CLO scale with 3 projectors
Example: CLO with 3 projectors
•
Light output:
-
Projector 1: 5000 lm
-
Projector 2: 4900 lm
-
Projector 3: 4800 lm
•
Match the light output of the projectors using the standard light source power feature.
-
Using 80% of Projector 3 in this example, all projectors now have a light output of 3840 lm
•
Enable CLO.
•
The CLO scale can now be used to set the light output to the same value on all projectors as the CLO has
been enabled on the same actual light output from all 3 projectors.
-
Note that the CLO scale value must be sent separately to all 3 projectors.
8.6.5 CLO stable signal
Signal stability
The light sensor, providing the CLO feature with data, requires time to stabilize when changing the light source
power in large steps using the CLO scale, e. g. from 80% to 20% when going from a day scene to a night
scene. This could cause an issue if the projector is used for training before the light output has stabilized.
When the CLO is enabled, a signal called hasstabilized will be available. The signal tells the user if the CLO is
stable or is still in a state of change, trying to obtain a stable light output.
The CLO hasstabilized signal only works when actively changing the CLO scale.
Rationale:
The CLO will change the light source power in small steps given the criteria: "average of measurements the
last 10 seconds shall not differ more than 0.75% from the set-point". This to maintain the desired light output.
From a user perspective no interaction has been made with the projector, so a change to the hasstabilized
signal in this case would not make sense.
The functionality presented in a Given-When-Then format.
