(2) Basic operation
1. Display switching: press set key to switch between different display states. Modify data: if the parameter lock is not locked, instrument
The numerical data displayed in the display window under the table can be modified by pressing ? (A / M), ▼ or ▲. For example: when the given value needs to be set, the instrument can be switched to the normal display state, and the given value can be modified by pressing ? (A / M), ▼ or ▲ key. At the same time, the instrument has the methods of rapid data increase and decrease and decimal point shift. Press ▼ to decrease the data, press ▲ to increase the data, and the decimal point of the digit can be modified and flash at the same time (as the cursor). Press and hold the key, you can quickly increase / decrease the value, and the speed will automatically increase with the decimal point moving to the right (Level 3 speed). Press the (A / M) key to directly move the position (cursor) of the modified data, and the operation is fast.
2. Manual / automatic switching: press ? (A / M) key to make the instrument switch undisturbed under automatic and manual conditions. When it is in manual mode, the first word of the lower display shows "m". When the instrument is in manual mode, directly press ▲ key or ▼ key to increase and decrease the manual output value. When automatic, press set key to directly view the automatic output value (the first word of the lower display shows "a"). By setting the "A-M" parameter (see the following for details), the instrument can not be switched to the manual state by the panel key operation, so as to prevent entering the manual state by mistake.
3. Set parameters: press the set key and hold for about 2 seconds to enter the parameter setting state. Press the set key in the parameter setting state, the instrument will display each parameter in turn, such as the upper limit alarm value alm1, parameter lock, etc. for the instrument configured and locked with parameter lock, only the parameters (field parameters) needed by the operator will appear. The parameter value can be modified by ▼, ▲, ? (A / M) and other keys. Press and hold the (A / M) key to return to display the previous parameter. Press the A / M key first, and then press the set key to exit the parameter setting state. If there is no key operation, it will automatically exit from the setting parameter state after about 30 seconds. If the parameters are locked (described later), only the field parameters defined by EP parameters (parameters and programs that can be defined by users and often need to be used in the work site) can be displayed, but other parameters cannot be seen. However, at least you can see the lock parameter displayed.
(3) Self setting (at) operation
When the instrument is used for the first time, the self-tuning function can be started to help determine the control parameters such as P, I, D, etc. When starting the self-tuning for the first time, you can switch the instrument to the normal display state, press ? (A / M) key and keep about two banknotes, at this time, the lower display alternately displays "at". After about 2-3 oscillations, the control parameters such as P, I and D are calculated automatically. If you want to give up self-tuning in advance in the process of self-tuning, you can press ? (A / M) key again and keep about two notes, so that "at" disappears. Depending on the system, the time required for self-tuning can vary from seconds to hours. After the successful self-tuning of the instrument, the parameter at will be set to 3 (1 when leaving the factory) or 4, so that the self-tuning can not be started from the panel by pressing the ? (A / M) key again in the future, so as to avoid human misoperation and restart the self-tuning. If the instrument that has started the self-tuning function once needs to start the self-tuning in the future, it can be started by setting the parameter at to 2 (see the description of "parameter function" later).
The parameter values obtained by the system setting under different given values are not identical. Before the self-tuning function is executed, the given value shall be set on the most commonly used value or the intermediate value. If the system is an electric furnace with good insulation performance, the given value shall be set on the maximum value used by the system, and then the self-tuning operation function shall be started. The setting of parameters t (control period) and hy (return difference) also affects the self-tuning process. Generally speaking, the smaller the setting value of these two parameters is, the higher the accuracy of self-tuning parameters is theoretically. However, if the hy value is too small, the instrument may cause the misoperation of the bit type adjustment near the given value due to the input fluctuation, so that the completely wrong parameters may be set. It is recommended that t = 0-2, hy = 0.3.
Manual self-tuning: since the self-tuning is implemented by bit adjustment, its output will be located at the position defined by the parameters outl and outl. In some cases where the output does not allow a large change, such as when some actuators use regulating valves, the conventional self-tuning is not suitable. This instrument has manual self-tuning mode. The method is to adjust manually first, and then start self-tuning in the manual state after the manual adjustment is basically stable, so that the output value of the instrument will be limited to the range of + 10% and - 10% of the current manual value instead of the range defined by outl and outl, so as to avoid the phenomenon of large-scale change of valves not allowed in the production site. In addition, when the response of the controlled physical quantity is fast, the manual self-tuning method can obtain more accurate self-tuning results.
(4) Parameter function description
The instrument defines the input, output, alarm and control mode of the instrument through parameters. The following is the parameter menu:

Return difference (dead band, hysteresis)
Parameter code Parameter implication explain set range
ALM1 Upper limit alarm    When the measured value is greater than alm1 + hy, the instrument will generate an upper limit alarm. When the measured value is less than alm1-hy value, the instrument will release the upper limit alarm. Set alm1 to its maximum value (9999) to avoid alarm effect. -1999-
+9999 ℃ or 1 definition unit
ALM2 Lower limit alarm     When the measured value is less than alm2-hy, a lower limit alarm will be generated, and when the measured value is greater than alm2 + hy, the lower limit alarm will be released. Set alm2 to the minimum (- 1999) to avoid alarm. +9999 ℃ or 1 definition unit
Hy-1 Positive deviation alarm   When artificial intelligence is used for adjustment, when the deviation (measured value PV minus given value SV) is greater than HY-1 + hy, a positive deviation alarm will be generated. When the deviation is less than hy-1-hy, the positive deviation alarm is released. When HY-1 = 9999 (the actual temperature is 999.9 ℃), the positive deviation alarm function is cancelled. 0-999.9℃
When the bit type adjustment is adopted, HY-1 and HY-2 will alarm as the second absolute value of upper limit and lower limit respectively. or
  0-9999℃
  1 definition unit
Hy-2 Negative deviation alarm   When artificial intelligence is used for regulation, negative deviation alarm will be generated when the negative deviation (given value SV minus measured value PV) is greater than HY-2 + hy, and the negative deviation alarm will be released when the negative deviation is less than HY-2 - hy. When HY-2 = 9999 (the temperature is actually 999.9 ℃), the negative deviation alarm function is cancelled. Ditto
Hy    Return difference is used to avoid frequent on-off of bit type adjustment or frequent generation / release of alarm due to fluctuation of measured input value. 0-200.0℃
  For example, the effect of hy parameter on the upper limit alarm control is as follows, assuming that the upper limit alarm parameter alm1 is 800 ℃, hy parameter is 2.0 ℃: or
  (1) When the instrument is in normal state and the measured temperature value is higher than 802 ℃ (alm1 + HY), it will enter the upper limit alarm state 0-2000℃
 (2) When the instrument is in the upper limit alarm state, when the measured temperature is less than 798 ℃ (alm1 HY), the instrument will release the alarm state. 1 definition unit
  Another example: when the instrument adopts position adjustment or self-tuning, assume that the given value SV is 700 ℃, hy parameter is set to 0.5 ℃, take reaction adjustment (heating control as an example).  
 (1) When the output is in the on state, when the measured temperature value is greater than 700.5 ℃ (SV + HY), it is off.  
 (2) When the output is in the off state, when the measured temperature is less than 699.5 ℃ (SV HY), it will be switched on again for heating.  
  For the position regulation, the larger hy value is, the longer on-off period is, and the lower control accuracy is. On the contrary, the smaller the hy value, the shorter the on-off period and the higher the control accuracy, but it is easy to cause the malfunction due to the input fluctuation, which reduces the service life of the mechanical switches such as relays or contactors.  
  HY parameter has no effect on artificial intelligence regulation. However, in the self-tuning parameter, because it is also a bit type adjustment, hy will affect the self-tuning result. Generally, the smaller hy value is, the higher the self-tuning accuracy is. However, the measured value should be prevented from misoperation due to interference and jump. If the digital runout of the measured value is too large, first increase the value of the digital filter parameter filt, so that the runout of the measured value is less than 2-5 digits, and then set hy as the instantaneous runout equal to the measured value.  
At control mode  At = 0, it adopts on-off, which is only suitable for control in the situation of low requirements.. 0-3
  At = 1, it adopts artificial intelligence regulation / PID regulation. Under this setting, it is allowed to start and execute self-tuning function from the panel.
 At = 2, start the self-tuning parameter function, and it will be set to 3 or 4 automatically after the self-tuning. 
  At = 3, it is adjusted by artificial intelligence. After the self-tuning, the instrument will enter this setting automatically. Under this setting, it is not allowed to start the self-tuning parameter function from the panel. To prevent misoperation and repeated start-up of self-tuning.
    1. P, D, t and other parameters are the control parameters of the artificial intelligence regulation algorithm. When at = 0, these parameters do not work. Because of the difficulty of temperature control in industrial control and the most extensive application, the definition of parameters is introduced with temperature as an example. 0-999.9
  I is defined as the difference of the measured value after the control object is basically stable when the output value changes. Generally, i-parameters of the same system will change with the measured values, and should be taken near the working point. or0-9999
  For example, for the temperature control of an electric furnace, the working point is 700 ℃, in order to find out the best I value, it is assumed that when the output is kept at 50%, the temperature of the electric furnace finally stabilizes at about 700 ℃, while when the output is 55%, the temperature of the electric furnace finally stabilizes at about 750 ℃. Then the best parameter value can be calculated according to the following formula: 1 definition unit
   I=750-700=50.0(℃)  
  The value of I parameter mainly determines the integral function in the regulation algorithm, which is similar to the integral time of PID regulation. The smaller I value is, the stronger the system integration effect is. The larger the I value is, the weaker the integration effect is (the integration time increases).  
  When I = 0 is set, the system cancels the integral function and artificial intelligence regulation function, and the regulation part becomes a proportional differential (PD) regulator. At this time, the instrument can be used as a secondary regulator in cascade regulation.  
P Rate parameter   P is inversely proportional to the change corresponding to the measured value when the instrument output changes by 100% per second. When at = 1 or 3, the value is defined as follows: 1-9999
  P = 1000 ÷ rise of measured value per second (measured value unit is 0.1 ℃ or 1 definition unit)
  If the instrument is heated at 100% power and it is assumed that there is no heat dissipation, the furnace will be heated at 1 ℃ per second, then:
P=1000÷10=100
 The p value is similar to the proportional band of PID regulator, but the change is opposite. The larger the p value is, the proportional and differential action will be strengthened, while the smaller the p value is, the proportional and differential action will be weakened accordingly. The P parameter is independent of the integral action. Setting P = 0 is equivalent to P = 0.5.
d Lag time  For industrial control, the lag effect of the controlled system is the main factor affecting the control effect. The greater the lag time of the system, the more difficult it is to obtain the ideal control effect. The lag time parameter D is a new important parameter introduced by the artificial intelligence algorithm compared with the standard PID algorithm. The xmd808 series instrument can carry out some fuzzy rule operations according to the parameter D, so as to be more perfect At the same time, the control response speed is optimized. 0-2000seconds
  D is defined as the time required for the furnace to start heating at a certain power without heat dissipation, when the heating rate reaches the maximum value of 63.5%. The unit of D parameter value in the instrument is seconds.
  D parameter has an effect on the proportion, integration and differentiation of the control. The smaller D is, the more proportional the proportion and integration are, while the differential effect is relatively smaller, but the overall feedback effect is enhanced; on the contrary, the larger D is, the less proportional and integral effect is, while the differential effect is relatively enhanced. In addition, d also affects the function of overshoot suppression, and its setting has a great influence on the control effect.
  If D ≤ t is set, the differential action of the system is cancelled.
t Output cycle  T parameter value can be set between 0.5-125 seconds (0 represents 0.5 seconds), which reflects the speed of instrument operation adjustment. The larger the value of T, the stronger the proportional effect and the weaker the differential effect. The smaller the value of T, the weaker the proportional effect and the stronger the differential effect. When the value of T is greater than or equal to 5 seconds, the differential action is completely cancelled and the system becomes a proportional or integral regulation. When t is less than 1 / 5 of the lag time, its change has little influence on the control. For example, if the system lag time D is 100 seconds, the control effect of t set to 0.5 or 10 seconds is basically the same. 0-125 seconds
 The principles determined by T are as follows:
(1) If SSR (solid state relay) or
Control silicon is used as the output actuator, and the control period can be shorter (generally 0.5-2 seconds), which can improve the control accuracy.
(2) When the relay switch is used for output, the short control period will correspondingly shorten the mechanical switch's
Life, at this time, the general setting T should be greater than or equal to 4 seconds, the larger the setting, the longer the life of the relay, but too large will reduce the control accuracy, so a value that can take both into account should be selected according to the needs.
  (3) When the output of the instrument is linear current or position proportional output (direct control valve motor forward and reverse), a small value of t can make the output response of the regulator faster and improve the control accuracy, but it may lead to frequent changes in the output current.
    
(5) Supplementary description of some functions
1. When linear current output of any specification (OP-A = 1)
The output upper limit and output lower limit define the current output specification of the instrument, and the range is arbitrary between 0-22ma. If 0-10mA output, set outl = 0, outl = 100 (unit: 0.1mA). 4-20mA is set to outl = 40, outl = 200. It can also be defined as non-standard output, such as 2-8ma output, setting outl = 20, outl = 80, etc. Note that setting outl must be less than outl for valid output.
2. Time proportional output (0p-a = 2; OP-A = 0 relay output or SSR voltage output)
Time proportional output is achieved by adjusting the on-off ratio (or high-low ratio of SSR voltage output) of the relay in a fixed time. The time proportional output can be regarded as a square wave whose period is equal to the control period T. the output value is proportional to the duty cycle of the square wave, and its value can be changed from 0% to 100%. Users with special requirements can use outl and outl to limit the range of time scale output values. For example: when the user needs to limit the output to 20-60%, set outl = 20, outl = 60. In general, when the time scale output is set to outl = 0 and outl = 100, there is no output limit.
Note: when OP-A = 2, the alarm output cannot be used.
3. External given
When the external setting allows (refer to the description of cool parameters), the instrument can input 1-5V voltage signal from the 1-5V terminal of its terminal to express its given value. The scale given externally can be determined by the p-sl and P-SH parameters. If the external given voltage signal is less than 1V, the external given function is automatically cancelled and the internal given value is used instead. When using the external given function, the instrument measurement input cannot use 1-5V / 0-5V, which has no effect on thermocouple, thermal resistance and MV voltage input. If the measurement input is 0-10mA or 4-20mA, set the main input of the instrument to 0-1v or 0.2v-1v, and then connect the resistance of 100 Ω or 50 Ω externally. The external given function enables the instrument to form a ratio or cascade regulation system to complete complex regulation functions.
4. Matching setting method with ytz-150 resistance remote pressure gauge
Instrument setting parameters: SN = 27

Note: display range = instrument display upper limit value - instrument display lower limit value
Resistance range = the resistance value corresponding to the range of remote resistance pressure gauge
Starting resistance = the resistance value corresponding to the starting of remote resistance pressure gauge
Full resistance = the resistance value corresponding to the full degree of remote resistance pressure gauge
Starting range = lower value of instrument display
Full scale = upper value of instrument display
