To change control cycle, please change JP1 and JP2 of PCB as below.
OUT ADJ. (output limit) (0 to 100%)
This function will be [Control input (%) × OUT ADJ. (%) =
Output] and it controls the power supplied into the load.
Although control input is 100% (5V or 20mA), the output is
the 50% which is proportioned with OUT ADJ. When not
using OUT ADJ. function, please make set value 100%.
※
This function must not be used in ON/OFF control
method.
SOFT START (0 to 50 sec)
This function protects the load in cases that the set
temperature is high, such as controlling the load (platinum.
molybdenum, tungsten, infrared lamp, etc.) in which inrush
current flows when power is supplied, or showing large
width of temperature rise during initial operation.
SOFT START set time (T) is the required time that output
reaches to 100%, and it is differentiated by OUT ADJ.
set value. For example, SOFT START is set as 10sec
and OUT ADJ. is set as 70%, it takes 7 sec to reach goal
output.
[Set time (T)×OUT ADJ. set value (%)=10 sec×0.7=7 sec]
If increasing the OUT ADJ. before output reaches to
goal output, it delays as much as the value, multiply of
increased value (%) and SOFT START set time. When not
using SOFT START function, please make set value 0.
※
This function must not be used in ON/OFF control
method.
OUT display
This is LED lamp to display the status of output and will be getting brighter according as output.
(0%: min. LED light, 100%: max. LED light)
3) ON/OFF control-Zero cross
This function is when control input is ON, output is 100%.
When it is OFF, output is 0%.
It is the same function as SSR (Solid State Relay).
(It always turns ON/OFF at zero point of AC.)
※
OUT ADJ. and SOFT START function are not
available in ON/OFF control method.
