3.6.1 How to calculate the delay
When there is only one system controller and
all the radiating panels are connected to the
controller with the cables that are of same length,
there is no delay to be considered. Under this
situation, all delay switches on all the radiating
panels should be set as 00, and the need of delay
signal should be confirmed.
Use the delay of the radiating panel whose
distance to the controller is the farthest, and then
use “+” and “-“ to adjust the delay of the other
radiating panels to make sure every radiating
panel have the same delay.
Formula：
◆ Cable delay coefficient 5.6ns/m；
◆ X：The displayed delay compensation factor
◆ L
MAX
-L：The max distance (meter) between
the controller and the radiating panel;
◆ L：the distance between the radiating panel
and the controller(meter);
Follow the steps to measure the length of the
cables to determine the settings of the delay
switch:
◆ Measuring the cable length from the
distribution host to each radiation board L;
◆ Make sure the maximum distance from the
distribution host to each radiation board L
MAX
;
◆ Calculate the difference from L to L
MAX
◆ Cable length with a calculated by multiplying
the cable signal delay difference between the rate
of radiation on each panel can be drawn to the
cable signal delay difference
◆ In addition to the signal delay in 25 poor, in
addition to be an integer (rounded)
Radiating board delay compensation switches to
set parameters.
◆ If necessary, to overlapping coverage areas,
away from the overlapping coverage area closer
to the delay of radiation panel switch settings
parameters do increase, as the radiation signal
delay compensation
◆ In accordance with the calculated setting
parameters to set the delay switch
3.7 Installation of the radiating panel
Infrared radiation panel can be installed on
walls or ceiling, with the package with a mounting
bracket and screws, install as shown below：
In determining the installation location
before, need to ensure smooth airflow
around the unit of radiation, radiation unit to
avoid the phenomenon of high temperature.
