Head-Feet Restrictions
HEAD-FEET is defined as "the sum of cable lengths from each color changer to a single
power supply output".
The HEAD-FEET parameter is a method of accounting for the voltage drop in the
power/signal cable caused by the current drawn by each color changer.
To help understand this issue, think of it as water pressure (voltage) in a hose (cable)
where you have multiple water sprinkler heads (color changers). If the hose (cable) is
too long or you have too many sprinkler heads (color changers), the water pressure
(voltage) will be too low.
The maximum HEAD-FEET for each of the CXI color changers is as follows:
Model 4560 4-inch CXI 750 head-feet max.
Model 7200 7.5-inch CXI 750 head-feet max.
Model 12210 12-inch CXI 500 head-feet max.
Model 7420 MultiPAR CXI 1500 head-feet max.
Model 16050 Large Format CXI 750 head-feet max.
"Head-Feet" Example:
There are three CXI Color Changers connected to a power supply. The Coloram II
Cable between the power supply and the first CXI is 100 feet long. The cables between
each of the CXI's is 20 feet long.
The amount of cable from the power supply to:
1st CXI 100 ft
2nd CXI 120 ft
3rd CXI 140 ft
total: 360 "head-feet"
Fan Speed Control
Set the fan speed control with the push-button / display via the FAN selection.
