In determining the installation location
before, need to ensure smooth airflow
around the unit of radiation, radiator to avoid
the phenomenon of high temperature.
3.6.1
How to calculate the delay
When there is only one transmitter and all the
radiator are connected to the transmitter with the cables
that are of same length, there is no delay to be
considered. Under this situation, all delay switches on
all the radiator should be set as 00, and the need of
delay signal should be confirmed.
Use the delay of the radiator whose distance to
the transmitter is the farthest, and then use “+” and “-
“ to adjust the delay of the other radiating panels to
make sure every radiator 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
transmitter and the radiator;
◆
L
：
the distance between the radiator land the
transmitter(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 radiator 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)
radiator delay compensation switches to set parameters.
◆
If necessary, to overlapping coverage areas, away
from the overlapping coverage area closer to the delay
of radiator switch settings parameters do increase, as
the radiation signal delay compensation
◆
In accordance with the calculated setting
parameters to set the delay switch

Installation of the radiator
Infrared radiator can be installed on walls or
ceiling, with the package with a mounting bracket and
screws, install as shown below
