 Precaution

DANGER! Caution! Electric Shock!

1. Do not touch the AC terminals while the power is supplied to the controller to prevent an electric shock.

2. Make sure power is disconnected while checking the unit inside.

WARNING!

This controller is an open-type temperature controller. Make sure to evaluate any dangerous application in which a serious human injury or serious property damage may occur.

1. Always use recommended solder-less terminals: Fork terminal with isolation. (M3 screw, width is 6.0mm)

2. Do not allow dust or foreign objects to fall inside the controller to prevent it from malfunctioning.

3. Never modify or disassemble the controller.

4. Do not connect anything to the “No used” terminals.

5. Make sure all wires are connected to the correct polarity of terminals.

6. Do not install and/or use the controller in places subject to:

y Dust or corrosive gases and liquid y High humidity and high radiation y Vibration and shock

y High voltage and high frequency

7. Must turn power off when wiring and changing a temperature sensor.

8. Be sure to use compensating wires that match the thermocouple types when extending or connecting the thermocouple wires.

9. Please use wires with resistance when extending or connecting a platinum resistance thermometer (RTD).

10. Please keep the wire as short as possible when wiring a platinum resistance thermometer (RTD) to the controller and please route power wires as far as possible from load wires to prevent interference and induced noise.

11. This controller is an open-type unit and must be placed in an enclosure away from high temperature, humidity, dripping water, corrosive materials, airborne dust and electric shock or vibration.

12. Please make sure power cables and signals from instruments are all installed properly before energizing the controller, otherwise serious damage may occur.

13. Please do not touch the terminals in the controller or try to repair the controller when power is applied to prevent an electric shock.

14. Wait at least one minute after power is disconnected to allow capacitors to discharge, and please do not touch any internal circuit within this period.

15. Do not use acid or alkaline liquids for cleaning. Please use a soft, dry cloth to clean the controller.

initial setting mode. Pressing the

key while in the regulation mode or initial setting mode, forces the controller to return to the

operation mode..

z 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.

Normal Iniput (Factory Setting) Current Input (4 ~ 20mA, 0 ~ 20mA)

 Display Unit Setting

Use following parameter to change the PV and SV display unit, select decimal point and switch between ℃/F.

¾ In Operation Mode

: SP=1 displays decimal place (ex: 25.5 degree); SP=0 displays integral number (ex: 25 degree).

¾ In Initial Setting Mode

: Select temperature display unit ℃/℉. (℉=℃* 9 / 5 + 32)

 Set Value and the Upper/Lower Limit of Input Value Setting

¾ 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”.

¾ 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”.

¾ 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

Value + Compensation Value.

For example: Measure Value=25.0; Compensation = 1.2. After applying to the Compensation equation PV=26.2.

Linear Compensation Gain (setting range = 0~0.999). Linear Compensation Gain Calculation equation: PV = Measure

Value* (1 + Gain/1.000) + Compensation.

For example: Measure Value=25.0; Gain= 0.100. After applying to the Gain calculation equation PV= 25.0 * (1 + 0.100 / 1.000) =

27.5。

If temperature deviation is the same in every temperature, settting linear compensation value can solve deviation problem. If temperature

deviation varies upon different temperatures, calculate the linear deviation error and adjusts the temperature by setting Gain and

Compensation value.

 Applications of Analog Voltage & Current Input

The input range of analog voltage and current are used as the uppler/lower limit of the controller’s voltage and current setting. When

setting up the desire voltage or current, it must lies within the range of upper/lower limit. For example: If the range of analog input voltage

is 0~5V, the upper limit setting will be 5000 and lower limit setting will be 0. If the decimal setting is set to 3 decimal place, a input voltage

of 2.5V will displays as 2.500. The equation of Display Value = (Upper limit setting of controller– Lower limit setting of controller)*(Input

voltage- Analog lower limit)/(Analog upper limit– analog lower limit) + Lower limit setting of controller.

 Disable the Cold Junction Function

The cold conjunction function of a thermocouple is set to ENABLE, but in some cases, we can set it to DISABLE.

¾ In Initial Setting Mode,

is used to set the first digit (Y) of Yxxx, (when Y=0, Enable; when Y=1, Disable).

Analog Output Compensation

When the output mode is set to analog current output (4~20mA) or linear voltage output (0~10V), user ’s desire output value can be

attained by using compensation function. For example, the analog output 1 can be adjusted in

and parameters in

“Regulation Mode”. The output value can be positive or negative (+/-) and it can be changed by pressing the Up/Down key on the

temperature controller. The scale of each pressing is an increase or decrease of 1uA and 1mV.

For example: To change the current output range from 4~20mA to 3.9~20.5mA, set

to 500 (20.5-20=0.5mA; 0.5mA/1uA= 500).

and set

to -100 (3.9-4=-0.1mA; -0.1mA/1uA=-100).

¾ To control the output manually: Set parameter

to in【Initial Setting Mode】.

¾ To set output to 0%: Set parameter

to or to in【Operation Mode】.

¾ To adjust the lower limit of analog output: Input a desire value and check the meter to adjust the analog input value to desire value

(For example: 4~20 m A, adjusting analog value will be 20 m A). Set parameter

(Output 1) or (Output 2) to your

desire value in 【Regulation Mode】.

¾ To set output to 100%: Set parameter

(Output 1) = or (Output 2) = in 【Operation Mode】.

¾ To adjust the lower limit of analog output: Input a desire value and adjust the analog input value to your desire value (For example:

4~20 m A, adjusting analog value will be 20 m A). Set

(Output 1) or (Output 2) to your desire value in

【Regulation Mode】.

 Retransmission and Compensation Adjusting

When the input value changes, the retransmission output will also be changed correspondingly. For example: If retransmission =

4~20mA ; uppler/lower limit = 100.0 ~ 0. Wen the controller reads 0, it outputs 4mA; when the controller reads 100, it outputs 20mA. The

value can also be a negative number to generate a negative slope. For negative slope, sets upper/lower limit = 0~100.0. In this case,

when the controller reads 0, it outputs 20mA; when the controller reads 100, it outputs 4mA. Refer to the slope diagram below.

Output = Negative Slope

Output = Positive Slope
