   It could cause an electric shock or fire.
6.Avoid using the product in flammable, explosive, humid, direct sunlight, thermal radiation, vibration and other places.
   It could cause a fire or an explosion.
7.Do not allow dust or cable residue to enter the product.
   Otherwise it may cause fire or damage the product.
8.After confirming the polarity of the terminals, connect the thermocouple wiring correctly.
  Otherwise it could cause a fire or explosion.
9.For the purpose of enhanced insulation, please use a power supply that ensures above enhanced insulation.

Functional specifications

1.Self-setting[]
PID self-tuning is the function of temperature controller to calculate PID control parameters by measuring the thermal characteristics and thermal response time of the control object, and through this function can realize automatic parameter setting to complete high-speed and stable control.
※ When self-tuning, the heating system should be in working condition, and the measured value PV should be lower than the set value SV.
※When the control mode parameteris in the state of "", the self-tuning switch[]will be displayed.
※ Set the self-setting switch[]to the state of "", and the AT indicator light starts to flash, indicating that the self-setting state has been entered.
※ During the execution of self-tuning, all parameter groups and SV setting values will be locked. If you want to interrupt the self-tuning manually, Set the self-tuning switch[]to the state of "".
※During self-tuning, if the fault code ""or""occurs, it will be interrupted automatically.
※After the completion of self-setting, the AT indicator will stop flashing, and the parametersobtained from setting will be saved automatically，And returns the control state to continue running with a new isoparameter.
※Interrupt self-tuning,parameters will not be modified.

2.Control mode
Control modeparameters under the state of"", the current PID control mode, if in the state of "", it is a bit control state.

3.Suppress overshoot []
For PID control, overshoot suppression adjustment, the larger the set value, the faster the heating, easy to overshoot;The smaller the setting value, the slower the heating and not easy to overshoot.Factory default is 60. It is recommended to get the set value by PID self-tuning.

4.Bit control return difference[]
Used to set the interval between ON and OFF of the control output in a bit control.
※When the control modeparameter is in the state of "", the bit return difference value[]will be displayed.
※If the return error range is too small, the control output may be unstable due to external interference and other reasons.

5.Error correction[]
This function is used to correct temperature errors caused by external sensors, etc., but the controller itself is basically error free.
If the actual temperature is 80 ° C but the controller shows 78 ° C, then set the error correction [] to"  ", and the controller's display temperature will become 80℃.
※Setting range -99~99℃.
※After error correction, if current temperature (PV) is out of range ""or"" will be displayed.

6.Digital Filtering []
Frequent changes of input signals lead to unstable display of current temperature (PV), which will affect the instability of the operation volume and thus lead to instability of the output. Therefore, this function is to filter the input signals to achieve stable control.
※1-30 is the first filtering, and 31-59 is the enhanced filtering.
※ Factory default setting is 50, suitable for most occasions, no special requirements without modification.

7.Alert type []

• Deviation alarm

Use when you want to interact with the set temperature.
The alarm action point will change with the change of setting temperature.

• Absolute value alarm

No need to interact with the setting temperature.

• Standby function

The attached standby function means that the alarm will not be ON even if the condition of "ON" is reached from the current value beyond the alarm range until it enters the next alarm range.

8.Alarm return difference []
Used for the difference needed to return to a non-alarming state from an alarming state.
If the alarm action point is 120 ° C, the alarm return difference value is set at 20 ° C. When the temperature reaches above 120 ° C, it will be in the alarm state; when the temperature falls below 100 ° C, it will return to the non-alarm state.
※ The setting range is 0~100℃.
※ Factory default is 1℃

Fault message indication

Matters needing attention

1.In order to eliminate inductive interference, please wire the product separately with high-voltage lines, power lines, etc.
2.Use the M3 terminal in the following shape.

3. Please use the power switch or circuit breaker when turning off the power to the product.

4. Please install the switch and circuit breaker nearby for the operator to operate.

5. If the product is used as temperature indication or adjustment, it should not be used as other instruments.

6. When using the thermal resistance (RTD) sensor, 3 wires should be connected. If you want to extend the wire, you must use the same type and length of wire connection.If the impedance of the line is different, it may cause temperature deviation.

7. When the power line and the input signal line have to be installed closer, please add a filter at the power end and shield the signal line.

8. Keep away from high frequency equipment (high frequency welder, high frequency sewing machine, high capacity SCR controller)

9. When the measurement input is switched on, HHH or LLL will be displayed if any error occurs. At this time, check whether the input is wrong after power off.

10.This product is used in the following environments.
①Indoor                                  ②Pollution level 2
③Altitude 2000m below         ④Installation classification LL

※ If you violate the above precautions, it may cause product failure. Please be sure to comply.
