Initial Start-up Setting
1.
When setting up
CND3
for first time
,
pres
s
key for more than 3 seconds till the screen display
and select according
to your temperature sensor type. Please be aware that a selection of wrong model would cause PV temperature display error. (Refer
to the chart below)
2.
When setting up the temperature sensor type by using RS-485, write your value (range 0~19) into register 1004H.
3.
When setting up the current input method, remove the temperature controller cover and set JP8 to short. (Refer to the chart below)

How to Set Up Current Input
Remove the temperature controller cover and set JP8 to short. JP8 jumper locates near the sensor input area on PCB board.

Display Unit Setting
Use following parameter to change the PV and SV display unit, select decimal point and switch between
℃
/F.
In Operation Mode
: SP=1 displays decimal place (ex: 25.5 degree); SP=0 displays integral number (ex: 25 degree).
In Initial Setting Mode
: Select temperature display unit

Set Value and the Upper/Lower Limit of Input Value Setting
Set the Upper Limit of Input Value: This parameter can be set in the Initial Setting Mode
, the upper limit input value must
be set within the range shown in the chart “Temperature Sensor Type & Temperature Range”.
Set the Lower Limit of Input Value: This parameter can be set in Initial Setting Mode
, the lower limit input value must be
set within the range shown in the chart “Temperature Sensor Type & Temperature Range”.
Set the SV: This parameter can be set in Operation Mode, SV value must be set within the range of upper/lower limit input value.
SV can not be set in In “Program Mode” or in “Remote Mode”.
Digital Filter and Linear Compensation Setting
In “Regulation Mode”,
and
parameters can be used to ajust the filter status and to avoid interferences on input signal.
: Filter Factors (setting range=0~50; factory setting=8). Digital Filter Calculation equation: PV=(Last displayed PV * n +
Measure Value)/ (n+1). When the parameter value is small, the PV display is close to the Measured Value. When the parameter
value is large, the PV response is slow.
: Filter Range (setting range=0.10~10.00
℃/℉
). If factory setting = 1, it means the controller will begin Digital Filter
Calcaulation when the Measure Value lies within the range of “Last displayed PV + / - 1.00
℃/℉
”. Therefore, it is recommended to
set a larger value when noise interferences is serious.
When PV display value is different than user’s expectation, Linear Compensation function can be set by
and
parameters in“Regulation Mode”.
: Linear Compensation Value (setting range= -99.9 ~ +99.9). Linear Compensation Calculation equation: PV = Measure
