1.Installation：
1）This product is used in the following environmental standards.
（IEC61010-1）[Overvoltage categoryⅡ、class of pollution 2]
2）This product is used in the following scope:surrounding environment, temperature, humidity and environmental conditions.
Temperature：0～50℃；Humidity：45～85%RH;Environment condition：Indoor warranty,The altitude is less than 2000m.
3）Please avoid using in the following places:
The place will be dew for changing temperature;with corrosive gases and flammable gas;with vibration and impact;with water, oil, chemicals,
smoke and steam facilities with Dust, salt, metal powder;and with clutter interference, static electric and magnetic fields, noise;where has air
conditioning or heating of air blowing directly to the site.
4）On the occasion of the installation, please consider the following before installing several.
In order to protect heat saturated, please ensure adequate ventilation space.
Please consider connections and environment,and ensure that the products below for more than 50mm space.
Please avoid to installed over the machine of the calorific value(Such as heaters, transformer, semiconductor operations, the bulk resistance).
When the surrounding is more than 50℃, please using the force fan or cooling fans.But don't let cold air blowing directly to the product.
In order to improve the anti - interference performance and security, please try to stay away from high pressure machines, power machines to install.
Don`t install on the same plate with high pressure machine and the product.
The distance should be more than 200mm between the product and power line.
2.Cable caution：
1)Please use specified compensation wire in the place of TC input;Please use insulated TC if the measured device is heated metal.
2)Please use the cable of lesser resistance in the place of RTD input,and the cable(3 wire) must be no resistance difference,but the total
length is within 5m.
3)In order to avoid the effect of noise,please put the input dignal away from meter cable,power cable,load cable to wiring.
4)In order to reduce the power cables and the load power cables on the effect of this product,please use noise filter in the place
where easy to effect.You must install it on the grounding of the disk if you use the noise filter,and make the wiring to be shortest
between noise filter output side and power connectors.Don`t install fuse and switch on the wiring of noice filter output side,otherwise it
will reduce the effect of noise filter.
5)It takes 5s from input power to output.If there is a place with interlocking actions circuit signal,please use timer relay.
6)Please use twisted pair with a shield for analog output line,to ensure the reliabilty of signal.
7)Please use twisted pair with a shield for remote RS485 communication cable,and deal with the shield on the host side earth,
otherwise it will reduce the effect of noise filter.
8)This product is not the fuse;please set according to rated voltage 250V,rated current 1A if you need;fuse type:relay fuse.
9)Please use the suitable screw force and crimp terminal.
The screw terminal size：M4X8（with 7.0X7.0 square base）
Recommended tightening torque：0.7N.m
Proper cables：0.25～1.65mm single cable/multiple core cable
10)Please don`t put the Crimp terminal or bare wire part contact with adjacent connector.
The instruction explain instrument settings,connections,name and etc,please read carefully before you use the temperature controller.

1、High & low limit display setting function
Example: use electronic ruler or others to measure , if want position 5mm display 500, position 6mm display 600, firstly enter into
function shield menu, make SF1= Y( open the functionof CAS, CAK parameter), then enter menu to set CAS=500 at 5mm postion,
and set CAK=600 at position 6mm, exit to the measure measure interface after finishing settting.
2、Linear signal self-calibration function
a）Set INP type, and make sure that it is one of the linear signals.
b）The input signal should input to correct input channel.
c）Enter low limit calibration menu CAL, press “ ” to flash “YES” ; and adjust the input signal to the minimum value.
d）When “YES” flashing, and the minimum value of input signal is inputed into the meter; press “ ” to confirm and save
calibration value.
e）After the low limit is calibrated, enter high limit calibration menu CAH, and flash “YES” in the same way.
f）Adjust the input signal to the maximum value, and input it into the meter. And when “YES” flashing, press “ ” to confirm
and save calibration value of high limit.
g）After calibration, enter CAE to change “N” into “Y” to enable calibration; otherwise, it will use the default calibration value.
h）The calibrated high limit input value of linear signal should not beyond the ±10% of the standard signal
i）After the calibration, if the result is not satisfactory, it can be recalibrated.
3、Transmition range calibration function
Example: actual high limit is 20.4mA, low limit is 3.97mA. To calibrate the transmition range through modification of OLL, OLH.
OLL= (Preset transmit low limit - actual transmit low limit)/ actual transmit range*1000 =( 4.0 - 3.97)/(20.4 - 3.97) * 1000 = 2
OLH= (Preset transmit high limit - actual transmit high limit)/ actual transmit range*1000+1000 = (20.0 - 20.4)/( 20.4 - 3.97) * 1000
+ 1000 =976

1 Read register（0x03）
For example: Host reads integer AL1（AL1=200）
The address code of AL1 is 0x3201, because AL1 is integer( 2 byte), seizes 1 data register. The memory code of decimal integer
200 is 0x00C8.
Note:It should read DP value or confirm DP menu value first to ensure the decimal point postion when reading data,and converse
the reading data to get the actual value. On the contrary ,it should converse the data to corresponding ratio first before writing the
data into meter.

For example: Host writes AL1（First alarm set value 100）
The address code of AL1 is 0x3201, because AL1
is integer ( 2 dyte), seizes 1 data register. The hexadecimal memory code of decimal
integer 100 is 0x0064.

Meter adopt Modbus RTU communication protocol, RS485 half duplex communication.Read function code:0x03,
write function code 0x06 or 0x10. Adopts 16 digit CRC check, the meter does not return for error check.

XⅠ．Methods of simple fault
XⅡ.Communication procotol
Abnormal communication processing:
When abnormal response，put 1 on the highest bit of function code. For example: when host request function code is 0x03, slave
response function code should be 0x83.
Error code:
0x02---Illegal address: the register address designated by host beyond the address range of meter.
Communication cycle:
Communication cycle is the time from host request to slave response data . ie: communication cycle= time of request data sending
+slave preparation time + response delay time + response return time.
Eg: 9600 Baud rate: communication cycle of single measured data ≥ 250ms.
Note: If there is any change, please subject to the drawing on the meter
Checks whether the input disconnection and whether normal of FH value,FL value,working
environment temperature and whether input signal is selected correctly.
