4. Installation and operation
Open the package, check the furnace and make sure the whole set is complete. Place the furnace on smooth ground or table. Keeps the controller avoiding vibration.
Install the power switch at the original power line to control the whole power. To make sure the equipment operates safely, furnace and controller must be grounded reliably.
Connect the controller direction to the line and make sure it is correct. Then put through the power, turn on the power and set the temperature on the meter. It starts to heating when indicator light of the meter turns green. Adjust the power to reach the target temperature as it is needed, but make sure the voltage and electric current of the product will not surpass the rated power.
5. Attentions
Install the outer ground protection to ensure safety of machine and experiment; ensure power as the machine required. |
This equipment is forbid to use in inflammable and explosive, poisonous and strong corrosive experiments. |
Make sure horizontal installation. |
Non-professionals are not allowed to disassemble and repair this machine. |
Pay attention to the setting temperature when dealing with inflammable matters. |
Make sure dry the resin container, if the temperature is setting too high by accident, the container would be dissolved and then fall on the heater, which will cause fire. |
Overfilled of sample will lead to overheat of working room under part, which will dissolve the inflammable material and cause fire. |
While the machine is working, don't touch the device top, as well as observation window and exhaust port to keep away from high-temperature burns. |
Please do not open the door when the temperature more than 500°C! |
please use the temp.50°C less than the Max. temp. for long hours use! |
Read the instruction book before operation. |
6. Meter operation instruction
1) Model Single-stage Temperature Controller
1.1 Basic display status
When powered on, it shows the basic display status, upper window displays real process value (PV) while lower window displays the set value (SV). If the real value overruns measure range(thermocouple breaks for example), upper window will display "orAL" and the highest and lowest values, at this time, controller will automatically stop controlling the output.
In controller's face, basically there are 6~10 LED lights,OP1,AU1,AU2,RUN which respectively stand for output, first alarm, second alarm, and working condition.
1.2 Time programm setting:
In basal display status, if the parameter lock "Loc" isn't locked, we can set setpoint (SV) by pressing 
, 
or 
. Press key to decrease the value, key to increase the value, and key to move to the digit expected to modify. Press 
till it shows "t1", we can set time.
1.3 Working control
When power on, the controller is in stop status, you can press for 2 seconds till the below window shows"run" to start controller's working. Press for 2 seconds till it shows "stop" to stop the controller's working.
1.4 Preparation
If you don't want to count time when it's still in raising temperature, you need this preparation. When you start preparation function,controller won't alarm when it shows unnormal value
(HaAL& LdAL). At this time, programmer stops counting time until the value is normal.
1.5 AI artificial intelligence control and auto tuning:
When AI artificial intelligence control method is chosen , the PID parameters can be obtained by running auto-tuning. In basal display status, press for 2 seconds, the "At" parameter will appear. Press to change the value of "At" from "oFF" to "on", then press to active the auto-tuning process. During auto tuning, the instrument executes on-off control. After 2-3 times of on-off action, the instrument will obtain the optimal control parameter value. If you want to escape from auto tuning status, press and hold the key for about 2 seconds until the "At" parameter appear again. Change "At" from "on" to "oFF", press to confirm, then the auto tuning process will be cancelled.
Note1 : If the setpoint is different, the parameters obtained from auto-tuning are possible different. So you'd better set setpoint to an often-used value or middle value first, and then start auto-tuning. Depending on the system, the auto-tuning time can be from several seconds to several hours.
Note2: Setting of CHYS may have influence on AT.. The lower value of CHYS the higher accuracy. But too low CHYS isn't advice, CHYS=2.0 is advice.
Note3: At the beginning after AT, the result maybe not table but it will get best result after a time.
Parameter Setting:
Note:All the internal parameter has been adjusted when factory test. Forbidden to modify them except Sensor Correction parameter.
In basal display status, press and hold for about 2 seconds can access Field Parameter Table.Pressing can go to the next parameter; pressing , or can modify a parameter.Press and holdcan return to the preceding parameter. Press (don't release) and then press key simultaneously can escape from the parameter table. The instrument will escape automatically from the parameter table if no key is pressed within 30 seconds. Setting Loc=808 and then presscan access System Parameter Table.

AoP | Alarm Output assignment | AoP is to define the place of HIAL,LoAL,HdAL alarms like : Value 0~4.0 means never alarm, 3and4 mean alarm from AU1,AU2. E.g. AOP=403 means HIAL alarm from AU1, HdAL from AU2.LoAL no alarm | 0~4444 |

Act | Dierect/reverse acting function | rE:Reverse acting.Increase in measured variable causes a decrease in the output,such as heating control. dr:Direct acting.Increase in measured variable causes an increase in the output,such as refrigerating control. rEbA:Reverse acting with low limit alarm and deviation low alarm blocking at the beginning of power on. drbA:Direct acting with high limit alarm and deviation high alarm blocking at the beginning of power on. | rE | ||||
P | Proportional band | Proportional band in PID with unit°C/F. Notes:normally use At to confirm P,I,D and Ctl .But can set known correct value. | 30 | ||||

d | Timeof Derivative | Time of derivative in PID.No derivative effect when d=0. Display unit is 0.1second | 50 | ||||
Ctl | Control period | Small value can improve control accuracy. For SSR output, generally 0.5 to 3.0 seconds. For Relay output, generally 15~40 seconds, because small value will cause the frequent On-Off of mechanical switch and shorten its service life. CtI is recommended to be 1/4 ~ 1/10 of derivative time. When control under on-off control,Ctl use as restart delay time affer off,for protect compressor application. | 2.0 or 20 | ||||
CHYS | Control Hysteresis | CHY is used for on-off control, if PV > SV, output turns off; PV<SV-CHYS, output turns on. | 2 | ||||

Scb | Input Shift | Scb is used to make input shift to compensate the error produced by sensor or input signal. PV_after_compensation= PV_before_compensation + Scb. Note:normally set it as 0 | 0 | ||||
FILt | PV input filter | The value of FIL will determine the ability of filtering noise. If great interference exists, then you can increase parameter "FIL" gradually to make momentary fluctuation of measured value less than 2 to 5. When the instrument is being metrological verified, "FIL" s can be set to 0 or 1 to shorten the response time. | 1 | ||||
