Description: When current input is selected, the input type must be voltage input ( at the same time, current range shall be indicated clearly in the brackets). Current and voltage input shall use the same connection terminal. If current input is selected, a resistance shall be connected parallelly at the input terminal. If the customers have confirm that the input type is current input, the manufacturer shall add a sampling resistance inside the instrument.

Notice:1. One 250Ω (1/2W，0.1%) sampling resistance has been installed inside the instrument, so the only thing needed to do is to connect the J4 jumper wire near the input terminal. You can parallel the resistance between the terminals 15 and 16.2. There is a thermocouple cold-junction compensation component inside the instrument. Connect shorting terminal 13 and 15. The inside cold-junction compensation function can be eliminated.

2 –3 Type, -4 Type and –5 Type Instrument Connection Diagram

Notice:

1. One 250Ω (1/2W，0.1%) sampling resistance has been installed inside the instrument, so the only thing needed to do is

to connect the J4 jumper wire near the input terminal. You can parallel the resistance between the terminals 9 and 10.

2. There is a thermocouple cold-junction compensation component inside the instrument. Connect shorting terminal 13 and

15. The inside cold-junction compensation function can be eliminated.

3 Select thermocouple cold-junction compensation model through connection

(1) Inside automatic compensation: all the instruments adopt this model when they leave the factory, which can meet general industrial applications. But because temperature sensors are installed inside the instrument, and is susceptible to the instrument interior working heat, as well as compensation lead connection and ambient environment ( like controllable silicon radiator). The worst warp because of these reasons can reach 2℃.(2) External compensation by connecting Cu50 copper resistance sensor: high compensation precision. For the users who need high precision measurement can purchase another small type Cu50 copper resistance. It is recommended to connect an outside junction box, putting the copper resistance and thermocouple cold-junction together and far away from all kinds of heat-radiating objects. The corresponding warp because of compensation is usually less than 0.5 0.5℃, so users with high precision requirements shall use this method.(3)Wiring diagram for three compensation mode:

Notice: The thermocouple cold-junction box is better to be far away from the heat-radiating objects

2 Parameters setup

SET SET SET SET

The meters have multiple functions and relative function parameters are varied. The consult and modification authority of all these function parameters should be controlled by software parameter Loc. Set Loc password as 111 and you can consult and modify all the function parameters. Under the status of setting parameters, click and hold fast key to check up the last parameter；if you click key first and hold fast, and then click SET key to exit the status of setting parameters. However, if the parameters have been locked by Loc, then this function should not be carried out. If setting Loc value as 0，you can only consult and modify part of the function parameters (parameters defined as on spot and definition method should be referred to hereunder). Take the Lc parameters for example, we will explain how to modify the values of parameters:

SET SET SET SET

Under the status of PV window displaying measurement values, click the SET key and hold fast for about two seconds, PV window will display the indicating signal of Loc parameter, when the SV window displays the value of parameter Loc as 0, then click key，the lowest digit of value 0 has one little point glittering at times (indicate current allowed modified position like cursor)

Under the status of PV window displaying Loc parameter indicating signal, click key (or key), you can increase (or decrease) parameter Loc value ( positions with glittering dot), click key to move dot positions.

Under the status of PV window displaying Loc parameter indicating signal, when the Loc value displays 111, click again SET key, PV window will display the indicating signal of first function parameter HIAL, SV window will display the parameter value. Click key (or key)，you can increase (or decrease) parameter value ( positions with glittering dot).

Under the status of PV window displaying HIAL parameter indicating signal, continue to click SET key, PV window will display the indicating signals of varied function parameters in turn, and the SV window will display parameter values. (on spot parameter definition methods)

In setting parameters, the display mode of last 8 parameters differs from former mode, seeing left diagram. PV window will display indicating signals of SET1~SET8, SV window will display the indicating signals of varied function parameters (such as, HIAL L﹑ oAL PHAL). ﹑ click key (or key), the parameter indicating signals in SV window will change in turn.Note: In setting parameters, if no operation within ten seconds, the meters will return automatically PV window to display the status of measurement values.

3 PID control parameter setting instruction(1)Hand adjust PID parameters:

The auto setting functions of the series of expert PID adjust meters have high accuracy which can satisfy the operating requirements of over 90% users. However, due to complexibility of auto control object and in certain special spots, auto setting parameters are probably not the best, so the hand adjust PID parameters is probably needed. If you can not acquire content control by operating right auto setting function, then the P、I、dt parameters can be hand ajusted. When you carry out hand adjust, you should pay attention to system response curve, if happening short periodic oscillation（equal with or longer than auto setting or position adjust oscillation period），you can decrease P（priority），increase I and dt；if happening long periodic oscillation (times than position adjust oscillation period), you can increase I（priority）, increase P,dt；if not happening oscillation but too big steady state error, you can decrease I（priority） ,increase P； if you can control steadily but with too long time at last, you can decrease dt（priority），increase P，and decrease I.

You can examine parameters in turn when debugging, which means that increase or decrease one of the parameters 30-50%, when the control effect is good, then you should continue to increase or decrease the parameter, or else adjust the parameters reversely, until the control effect satisfy the requirements. In general, you can modify I, if not satisfying the requirements, modify in turn the parameters of P, dt, and t until the control effect satisfy the requirements.(2)Meter PID parameters auto setting

When using the meter in the first time, you should make use of meter auto setting function to confirm the control parameters (parameters of P, I and dt) in order to achieve the ideal control effect. When you

find out the PID control effect is not good, you can start up the auto setting function once again. Click and hold fast key for about two seconds and then disengage the key until SV window displays “At”. The meter will enter auto setting status. When meters auto setting, they will carry out position adjust after two or three oscillations.

The meters will set automatically the PID control parameters (parameters of P, I and dt). The meters will return automatically auto control status after auto setting function. In auto setting, if you want to give up auto setting process, you can click and hold fast the key for two seconds and then disengage the key until SV window stop displaying “At”, then you will give up auto setting function.[note 1] when the auto setting function is carried out successfully for one time, then the meters will not be operated to start up auto setting function by clicking key, in order to prevent manmade wrong operation. When the meters which have started up the auto setting function for one time need to start up the auto setting another time, you can start up the auto setting function by setting the parameter of tAd as 2 (see instruction hereunder)[note2] according to different systems, auto setting time will range from seconds to hours.[note3] the auto setting accuracy is connected with the following factors. Users should understand these factors before starting up the auto setting function. ① According to different set value, the system will display different control parameter values. So the auto setting should be carried out accordint to system common set value. If the set value changes at times, then you can carry out the auto setting on the medium value. ② T(control period) and dF(return difference) parameters have also influences to auto setting accuracy. In general, the smaller these two parameter values are, the higher auto setting parameter accuracy is. However, the values of dF should have bigger fluctuation amplitudes than input signal values. The limits of t should be explained hereunder.[note 4] When the meters are used first time after auto setting, the control effect is probably not the best. Some certain time should be needed to acquire the best control effect（ in general it is equal to time needed by auto setting）.

2 Specific instructions of parameters(1)Software lock parameter (Loc)Loc is used to control parameter setting authority, when the values of Loc are set as beyond 111, the meters will only allow display to set 0~4 onspot parameters (defined by SET1~SET4) and the parameter of Loc. When parameter value of Loc=111, users can set all the parameter values. Loc parameters will supply multiple different parameter operation authority. When the technicians of users finish the settings of meter input and output parameters, they can set the parameter value of Loc as numbers beyond 111 to prevent onspot operation workers from modifying certain important parameters. The specific instructions are as follows: Loc=0，allow only to modify set values and onspot parameters Loc=1 ， display and view onspot parameter, do not allow to modify parameters(except Loc parameter) and allow to set the set values. Loc=111，set all the parameters and set values

(2)Meters measurement display set parameters (Sn、dIP、dIL、dIH、SC、dL) Sn is used to set input signal type. When users need to modify input signal type, they should modify the

“Sn”parameters to relative values, seeing “input signal type table”. In addition, when the meters is connected with current input, you should first of all transfer the current signals to voltage signals (parallel connect resistance on the meter terminals) and then input them into meters,then the in input specification parameters should be selected according to voltage signal amplitudes.

dIp is used to set dot point positionsDip is used to define the dot point positions to coordinate with display values which users are

accustomered to. To modify dIP setting will only influence the display and not influence measurement accuracy. When dIP=0, the display format is 0000，when dIP=1, the display format is 000.0，when dIP=2, the display format is 00.00，when dIP=3, the display format is 0.000.

dIL and dIH is used to set input display range. dIL indicates the input signal lower limit display range;dIH indicates the input signal upper limit display range, the display ranges of the signal values are -1999~9999(dot points are defined by dp). Suppose that the input signal ranges are 0~5V ， acquired display ranges are 0~1000，meter display resolution is 1. Then the display parameter setting methods are：Sn=34，dIL=0,dIH=1000,dp=0 with 0000 format.

SC is used to set the meter input signal translation amendment values to compensate the errors of transducer or input signal. SC parameters coincide with display.

For example: when the current display value is 0.5， but the real value is 0.0， in which the difference value is +0.5，set SC value as －0.5 when modifying, then the display value changes into 0.0.

Note：meters are carried out inner modification when released from the factory, so SC parameter value is 0 when released from factory. The parameter is only modified by users when users believe that the measurement needs to be modified once again. DL is used to set the meter digital filtering system function to deal with the display number bouncing due to disturbance. dL=0~20 (the bigger dL value is, the accurater measurement value is, but the slower the response speed is). When the meter measurement is disturbed on the spot, you can increase step by step the dL value，until the instant bounce of measurement value is less than 2~5 numbers.

Note：when verifying the meter, you should set dL parameter as 0 to increase the response speed.

(3)Meter alarm setting parameter (HIAL、LoAL、PHAL、PLAL、ALP、dF) HIAL、LoAL are used to set upper limit and lower limit alarm limits. When the alarm condition is satisfied, meter alarm relay actions (normal close contact break/normal open contact attracting)， the alarm light illuminates in the meter front panel. The alarm will be cancelled when the alarm factors are removed. PHAL、PLAL are used to set positive deviation and negative deviation alarm limit values. When the alarm condition is satisfied, meter alarm relay actions (normal close contact break/normal open contact attracting)， the alarm light illuminates in the meter front panel. The alarm will be cancelled when the alarm factors are removed automatically. ALP is used to set the alarm mode of alarm position. ALP parameter setting range should be 0~127 to define HIAL、LoAL、PHAL、PLAL alarm function output positions which are defined by the following formula:A=0，upper limit alarm is output by alarm position(AL1) A=1，upper limit alarm is output by alarm position(AL2) B=0，lower limit alarm is output by alarm position(AL1)B=1，lower limit alarm is output by alarm position(AL2)C=0，positive deviation alarm is output by alarm position(AL1)C=1，positive deviation alarm is output by alarm position(AL2)D=0，negative deviation alarm is output by alarm position(AL1)D=1，negative deviation alarm is output by alarm position(AL2)E=0，alternate to display alarm character in SV display window when alarming, such as HIAL、LoAL to understand fast the reason of meter alarm;E=1，do not alternate to display alarm character in SV display window when alarming ( but except orAL) in general to be used for setting the alarm as control occasion. DF is used to prevent alarm output constant make and break due to measurement input value fluctuation, which are also called return difference, insensitive interval, dead zone and lagging loop and so on. dF parameter influence to upper limit and lower limit alarm control is as follows: when A=1， the other items are 0，upper limit alarm is output by alarm position:

Suppose the upper limit alarm parameter HIAL is 800℃， dF parameter is 2.0， and when the

measurement temperature value is more than 802, (HIAL＋dF)，the meter will enter upper limit alarm status. When the measurement value is less than 798 (HIAL－dF)， the meter will remove the alarm status.

(4)Meter PIDcontrol setting parameters (opAd、P、I、dt、T、ot、oL、oH) opAd is used to set meter control mode.

opAd=0： adopt position adjustment (ON--OFF)， suited only to control the occasion with lower requirements opAd=1：adopt expert PID adjustment，the setting is released setting, under the status of the setting, starting up auto setting function is allowed on the panel. opAd=2：adopt expert PID adjustment， start up the auto setting function after finishing parameter setting. The auto setting will set as 3 or 4 after auto setting. opAd=3：adopt expert PID adjustment， the meter will enter the setting after auto setting, under the status of the setting, starting up auto setting function is not allowed on the panel. opAd=4：adopt expert PID adjustment，similar with the occasion when opAd=3，but the parameter P is defined as 10 times than before，that is, when opAd=3，P=5， and when opAd=4，and when P=50, both have same control effect. For the control to fast changing physical quantity, (for example, temperature change is more than 200℃ in one second) ， and the control occasion of frequency governor，when opAd=1、3，the value of P is very small，sometimes when the value is less than 1, it can satisfy the control need. Then when setting opAd=4， then the value of P value can be magnified 10times to acquire accurater control. P value is similar to PID adjust proportional band，but the change is reverse. When the P value becomes bigger， the effect of proportion and derivative action will increase by direct ratio；When the P value becomes smaller，the effect of proportion and derivative action will decrease. The P value has nothing to do with integral action. When opAd=4，the value of P will increase ten times. The I parameter value of same system in general will differ with measurement values and it should be according to the near ofhte working point. I value mainly decides on the integral action in the adjustment arithmetics and expert PID adjustment function，similar to PID adjustment intergral time. The smaller I value is, the stronger system integral action effect is . The bigger I value is, the poorer system integral action effect is (the integral time will increase)。 When I is 0， the system will remove the integral effect and expert PID adjustment function， the adjustment part will become as proportional differential (PD) regulator，and then meter can be used as secondary regulator in the cascade control. dt value has influence effect to control proportion, integral action, differential, When the dt value becomes smaller ， the effect of proportion and integral action will increase by direct ratio, and differential action will decrease comparatively. However, the overall feedback effect will increase; whereas, when the value of dt becomes bigger， then the effect of proportion and integral action will respectively decrease, and differential action will increase comparatively. In addition，the value of dt will also influence the development of overshoot inhibit feature whose setting will have strong influence to control effect. When setting dt≤T the system differential action will be removed. T is used to set output cycle with the unit as second. T displays the speed of meter operational adjustment. The bigger T value is，the stronger the proportional action, the poorer the differential action. When the T value becomes smaller，then the proportional action will decrease, and the derivative action

will increase. When the value of T is more than or equal to 5 seconds，then the derivative action will be removed，the system will become proportional or proportion integral adjustment. When the value of T is smaller than 1/5 of d value，then its change will have little influence to control effect. For example, when the parameter value of d is 100，then the control effect of setting T as 0.5 or 10 seconds is similar.T defines the following principles: The small T value can make regulator output faster response and higher control accuracy. But it will lead to frequently changing output, and you should select one compromise value according to demand.

SET1~SET4 is used to set 1~4 onspot parameters， in which SET1is set steadily as Sn, other parameters, namely the open parts, is convenient for onspot person to modify. For example： certain spot wants to modify HIAL(upper limit alarm)、 LoAL(lower limit alarm)， you can set

SET2=HIAL、SET3=LoAL，and set parameter lock Lct value as 0.
