note①The equipped sensor must be an isolated type (i.e. sensor)2The root lead is insulated from the external metal protective tube.

note②When the usersomeOne input signal is0～5V、1～5VWhen simulating signals, the input type cannot be changed to thermocouple or thermistor signals because the hardware of the instrument is incompatible with thermocouple and thermistor signals. But the settings between thermocouple and thermistor signals can be changed arbitrarily.

IIIBasic settings and operations

1First level menu settings

Press the function key（SETKey)3In seconds, enter the first level menu, and at this point, '...'1Road display window 'and' Section '2The 'road display window' displays parameter symbols and parameter values respectively. You can press the ◄ (shift key), ▲, and ▼ keys to change the parameter values. After modification, pressSETSave key to enter the next parameter; Modify other parameters using the same method.

2Secondary menu settings

Each channel parameter is adjusted according toCH1TheCH2TheCH3TheCH4Three seconds to enter the corresponding channel menu item, you can press the ◄, ▲, ▼ keys to change the parameter values. After completing the modification, pressSETSave key to enter the next parameter; The parameters are shown in the table below:

3Set the given values for each channel

pressCH1TheCH2TheCH3TheCH4Three seconds to enter the corresponding channel menu item (secondary menu), appearsSUParameter, press the ◄, ▲, ▼ keys to modify the parameter value, pressSETSave key.

6、 Self tuning operation

First, set the settings and then enter the menu，Set the hysteresis as0.5～1Left and right, willATset to1The instrument enters the self-tuning state, and the corresponding display window flashes“AT”At this point, the instrument is in positional control, and after three oscillations, the instrument determines a new onePTheIThedWait for the parameters and save them, then reset the instrument and enter the control state.

7Fault analysis and troubleshooting

1When the instrument window displays“HHorLL”Please check if the sensor wiring is correct.

2When it is found that the temperature between channels affects each other, please check whether the equipped sensors are isolated.

8、 Communication ProtocolThe communication function is optional and needs to be explained before orderingIf communication function is not required, there is no need to read this section

1The communication baud rate is1200、2400、4800、9600Four adjustable levels, data format is1A starting position8A data bit,1A stop bit without a checksum. The parameters that need to be set on the instrument include:OPbTheAddCommunication device address (instrument number)btCommunication baud rate.

2Read parameters from the upper computer(support1-4a character)

3Instrument response:(1-4a character)

4Write a parameter on the upper computer（1One word),The format of the instrument response frame is the same:

in the above tableCRC16Verification code according to standardModbustuCommunication protocol calculation, with low bits at the beginning and high bits at the end.

5The parameter code and register address can be found in the instrument manual<Menu parameter table>.

6Besides<Menu parameter table>In addition to the register addresses in, the following table shows several commonly used register addresses. (Note ①)

Note 1: For each channel mentioned above4Each register only supports continuous global reading. For example: using03Function code, read once6144～6147The instrument will also return four parameter values at once for the four consecutive register addresses in.

Note 2: The address is6144、6148、6152、6156The data stored in the register isWORD, containing16aBITThe information is as follows:

AL=1An alarm will occur;AT=1The instrument is in a self-tuning state;D0～D7To output percentage（0～100）.

7For the convenience of users, we also store the measurement values of the four channels in the following consecutive register address blocks, which also support one-time reading.

9、 Supplementary Explanation for Communication

1The program part of the upper computer for writing data to the instrument should add parameter limiting function according to the specifications of the instrument to prevent data beyond the range from being written to the instrument,

Make it unable to function properly. Please refer to the previous "Instrument Manual" for the parameter codes, register addresses, and rangesThe menu table in.

2The interval time for the upper computer to send read or write instructions should be greater than or equal to0.1Second, if it's too short, the instrument may not be able to respond in time.

3The measured value is32767（7FFFH）ExpressingHH(Beyond the upper range), for32512（7F00H）ExpressingLL(Exceeding the lower range)

4BesidesCRCVerify that the low bits of the byte are in the front and outside,All other double bytes have high bits in front.

5The instrument has not sent decimal point information, so it should be set as needed when programming the upper computer.

6Single bus mounting20The communication quality below the station is relatively stable. If more mounting is required, it is best to connect to ensure communication stability485Repeater.

7Because there are some on the marketmodbusThe first address of the parameter register address for smart devices is from1At the beginning, some0Start (this instrument)

from0Start). Therefore, when communicating with some configuration software or touch screens, all parameter register addresses of the instruments in the table above need to be

plus1To read and write correctly.
