    1.3.4 Electric isolation of the modules There are a group of 24V and a group 12V power supply built in the instrument and isolated to the main circuit. The 24V power commonly supplies voltage output module, such as V24/V12/V10, I2 and I4. The 12V power is commonly supplies output or communication module.

Compared to the relay contact output module, W1 and W2 have longer life and lower interference. They can largely lower the interference spark of the equipment, and greatly improve the stability and reliability of the system. Since the driver element is TRIAC, it is suitable for controlling 100-240VAC (not for DC power) with current up to 80A.

  • Page 25: Auto Tuning

    “on” to “oFF”, press to confirm, then the auto tuning process will be cancelled. Note 1: AI-518 instruments apply the advanced artificial intelligence algorithm, which has avoided the overshoot problem of standard PID algorithm, and achieve precise control. Note 2: If the setpoint is different, the parameters obtained from auto-tuning are possibly different. So you’d better set setpoint to an often-used value or middle value first, and then start auto-tuning.
  • Page 26 Note 4: In a heating/refrigerating dual output system, auto tuning should be executed at the main output (OUTP). Note 5: AI series instrument has the function of self-adaptation. It is able to learn the process while working. The control effect at the first run after auto tuning is probably not perfect, but excellent control result will be obtained after a period of time because of self-adaptation.

Allowed to quick activate auto-tuning (pressing in basic display status.) 2: AI MPt control. Activate auto-tuning. 3: After auto-tuning finished, the instrument automatically set CtrL=3, and quick auto-tuning function is disabled.
  • Page 30 Parameter M5, P, t, CtI etc. are only for AI MPt control, and have no effect to on-off control. M5 is defined as measurement variation after output is changed by 5% (0.5mA if OP1=1) and when controlled process is basically stabilized. "5" indicates that output variation is 5 (5% or 0.5mA).
  • Page 31 P is in reverse proportion to measurement variations caused by output changes by 100% in one second. It is defined as the following: if CtrL=1 or 3, then P=1000/measurement variation per second, the unit is 0.1 or 1 defined unit . Ex., instrument use 100% power to heat and there is no heat loss, if temperature 0～9999 in crease 1...
  • Page 32 Parameter t is applied as one of the important parameters of AI artificial intelligence control algorithm. "t" is defined as follows: time needed for a electric furnace from the beginning of elevating temperature to get to 63.5% against the final speed of temperature elevating, provided there is no heat loss.
  • Page 33 Small value can improve control accuracy. For SSR, thyristor or linear current output, it is generally 0.5 to 3 seconds. For Relay output or in a heating/refrigerating dual output control system, generally 15 to 40 seconds, because small value will cause the frequent on-off action of mechanical switch or frequent heating/refrigerating switch, and shorten its service life.

Intermediate value filter takes intermediate value among three continuous values, while integral filter has the same effect as resistance-capacity integral filter.
  • Page 42 For AI-518P, parameter RUN is used to define the event-handling mode when program is running. Abrupt actions affecting control execution of program are called event, as the outcomes of events are always probably unpredicted, the aim of event handling is to turn those unpredicted things into predicted results.
  • Page 43 planed. This mode guarantees constant running time of the program, but it can’t guarantee the integrity of the whole curve. D=1, With the function of PV startup and without the function of preparation. D=2 With the function of preparation and without the function of measurement value startup.
  • Page 44 Loc can be set to other values than 808 in order to avoid field operators’ accidental modification of some important operation parameters. See the following: for AI-518 series instrument Loc=0, allowed to modify field parameters and setpoint. Loc=1, allowed to view field parameters, and to set setpoint. But the modification of field parameters (except parameter Loc itself) is not allowed.
  • Page 45 1 to 8 field parameters can be defined by parameters EP1to EP8. If the number of the field parameters is less than 8, the first idle EP parameter should be set to “nonE”. The initial values of EPs and Loc are EP1=HIAL, EP2=LoAL, EP3=HdAL, EP4=LdAL, EP5=nonE, EP6=nonE, EP7=nonE, EP8=nonE and Loc=0.

It can continuously adjust heating power by control the conduction angle of thyristor. With non-linear power adjustment according to the characters of sine wave, it can get ideal control.

  • Page 47: Setpoints Switch

    When number of the instruments is big enough, 2 or more computers can be used and built into a local network. AIDCS application software, a distributed control system software developed by Yudian, can control and manage 1～ 160 AI instruments, record the data, generate and print reports. If users want to develop their own distributed control system by themselves, the communication protocol of AI instruments can be free offered.
  • Page 48 3.3.5 Temperature re-transmitter / set current output Besides AI PID, stand PID control and on-off control, if the output is defined as current output, the instrument can also retransmit PV (process value) or SV (setpoint) into linear current and output from OUTP. The precision of current output is 0.2%FS.
