HMT-JK Series Eight-Channel PID Temperature Controller HMT-JK

Specifications and Product Details:

HMT-JK series digital temperature control meter

Operation Instruction.

The HMT-JK series digital temperature control meter can connection 8 road sensor and control 8 road temperature at one time. It is advantage for connection at scene.

Main technical standard.

1) Input: Thermocouple: K ,J ,S ,E .

2) Display precision: superior to 0.5 degree.

3) Control method: ON/OFF drop in level control, PID control.

4) Output method: 7A relay(suggest blow 1A ).

5) Working power: AC220V 50Hz , the power’s consumption is less than5W.

6) Size: 80 x 160 x 110 ; Installation hole: 76 x 152

The face have 8 displays, difference use show every single road measured value every one time.It has a radix point right LED every display, the radix point is turning on, this way has control output. The radix point is turning off, this way hasn’t control output.

When the sensor is not connected,it display “HH”.

1,Set the temperatue parameter for each channel: Press the key enter into the first channel menu parameter, press the or key to Decreases or Increases the parameter value, finish setting , then press will set the next channel. If within 10 seconds do not press every key then it will automatically preserve and return out.

2,Set the system parameter: Press the key enter into system parameter menu, it first displays the parameter name ,wait for a while,the parameter can be changed.In this time code and parameter value will alternate display, press the or to Decreases or Increases the parameter value. when the setting finished, press key will enter into the next parameter setting. Use the same idea to set other parameter. If within 10 seconds do not press every key then it will automatically preserve and return out.

system parameter
Code	Description	Remarks
LOCK	Configuration privilege	When LOCK number is 222,it can be enter into set
T	Control period/output(S) smooth	Parameter T is used to balance proportional function and derivative function. The sampler T is set, the stronger derivative function is and the weaker proportional function is, but proportional-derivative function as a whole keep unchanged.
HY	Deadband	Deadband parameter HY is set to permits protection of position control output from high switching frequencies caused by process input fluctuation. Deadband parameter is used for position control,
SN	Input specification	Thermocouple: K ,J ,S ,E ; Thermal resistance: PT100 ,Cu50 Resistance Type controller: 0: PT100, 1:Cu50 Thermocouple Type controller. 0:K, 1: E,2:J,3: S Note.Resistance Type controller and Thermocouple type controller are different type.
ADD	Communication address
BAUD	Communication baud rate	Suggest:9600bps
CN	Type of communication	0.the interface is RS485 1. for special printer.
T1	Year of printing	For printer special
T2	Month of printing
T3	Day of printing
T4	Hour of printing
T5	Minut of printing

Channel parameter setting:

Press the key to the channel you want to set,then press key to set channel prarmeter“Sc,P,I,D,AT”.

1) Sc

Input shift parameter Sc

Parameter Sc is used to make input shift to compensate the error produced by sensor or input signal itself. For thermocouple input, parameter Sc is used to correct reference junction compensation error.The instrument itself will not produce error after a long time used, because the technology of digital calibration is used in the instrument to substitute potentiometer of bad stability, and the function of automatic zero modulation will guarantee no zero drift produced in the instrument.

Parameter "Sc" is used to make input shift to compensate the error produced by measurement. For example, provided input signal keep unchanged, if when parameter "Sc" is set to 0.0°C, the temperature measurement of the instrument is 500.0°C, then when parameter "Sc" is set to 10.0°C, the temperature measurement display will be 510.0°C.

Instruments are all calibrated before delivering, and so the default value of parameter "Sc" is zero. Only adjust this parameter when recalibration of measurement is necessary.

2)PID

P=0,close PID control,and start the ON/OFF control,P≠0, start PID control,and is no use.

After the Sc is P,I,D setting.

3) Auto turning

Ater the P,I,D is auto turning, =0,close the auto turning, =1 start the auto turning
