NOTE
If a lighting bus (any selection other than PHOTO ) is selected, and the lighting bus
control is turned to its minimum (daytime) setting, the display brightness tracks the
400W Series unit‘s photocell using additional parameters (PHOTO TRANS % and
PHOTO SLP/OFFST) described below.
PHOTO TRANS % - (Photocell Transition Percentage)
When a lighting bus is used to control the lighting of the
display (see Figure 5-12), this parameter sets the point on
the lighting bus control below which the display
brightness tracks the 400W Series unit‘s photocell. This
field has a range of 0 (zero) to 99, and is set to 25 at the
factory.
PHOTO SLP/OFFST - (Photocell Slope/Offset)
These fields are equivalent to the SLOPE/OFFSET fields
described above, with the exception that they only control
the display lighting characteristics when the lighting bus control is below the level specified in the
PHOTO TRANS % field. Both fields have a range of 0 (zero) to 99, and are set to 50 at the factory.
