5.4 How to set each function and description of function 5.4.1 Auto-tuning (AT) function ■ What the auto-tuning is • Auto-tuning (AT) is a function to operate turning on and off a subject of control so that the PID parameter best suited for a set temperature is automatically calculated and set. • For AT, ensure to wire the input 1 terminal and output terminal (such as power supply for heater), set the setting temperature (SV), and use the equipment in a state possible to be controlled.
Re-execution of AT PID parameters calculated by AT are not necessarily best suited for all states. Re-execute AT because best suited control may not be possible for cases listed below where settings or states are changed.
■ Post-AT control characteristics per control type Note The control characteristics graph is an example and may differ depending on subjects of controls. Take care it.
5.4.2 Self-tuning function ■ What the self-tuning is • Self-tuning is defined as a function that automatically executes tuning without requiring operator to provide instructions and corrects the PID constant at the time of operation start (including power-on), change of setting value or generation of hunting. • Ensure to execute the self-tuning in a controllable state after the input 1 terminal and output terminals (such as the power supply for heater) are wired, and the setting temperature (SV) is set.
Note Precautions on the use Self-tuning is affected by the present control results, as it is a function to correct the PID constant using responses from the normal control. Under the following environments, precise compensation may not be possible. (1) Control system with large disturbances (when hunting-like operation appears due to disturbances) (2) Control system with much time required for providing control outputs Under the following cases, use auto-tuning.
5.4.3 Mode/manual function ■ Mode (MD)/manual (MAN) function Controls set in the control mode and manual controls can be switched over using the FUNC key, DI or communication. Changeable controls are RUN, READY, MANUAL and timer controls in the control mode (MD) of SET 4. The control mode (MD) can be changed using the ▽ key or △ key. The following explanation is for switching over the control mode (MD) to RUN.
5.4.4 Bank function ■ What the bank function is • The bank function is a function that enables a desired control to be effective through changing the bank settings for which parameters are preset in each bank and thereby no change of temperatures, PID values or alarm settings are required each time when different temperature controls or alarm settings are set on a single unit of this equipment. Eight memory banks, or banks 0 to 7, are available.

■ Complementary explanation of “RDY lamp” lighting status The table below shows an indication status of the RDY lamp when timer operation is set for control mode. The indication status varies depending on the SET 04 control MD status (MD/READY).
5.4.6 Loop abnormality function ■ What the loop abnormality is The function is to detect an abnormality in the control loop. When a value falls in the judgment domain with respect to the conditions of the control loop anomaly MV threshold(MS*) and control loop anomaly PV threshold(tS*), the control loop anomaly PV change threshold is judged at each “LoP*” time. A loop abnormality is determined if each change threshold is judged to be equal to or below “PS*.
< How to set > Power-on About 4 seconds (automatic) Operating mode MODE key: 2 seconds Input 1 setting mode SET 01 screen △/▽ key Control setting mode SET 04 screen MODE key Primary control loop abnormality time setting LoP 1 Set the primary control abnormality time setting, using the △/▽ key. MODE key Secondary control loop abnormality time setting LoP 2 Set the secondary control abnormality time setting, using the △/▽ key.
5.4.7 Current transformer (CT) abnormality function ■ What CT (current transformer) is • CT is a function to detect that outputs are not properly turned on and off due to failure of relays or SSRs. • For detection of failure, using CT, ensure to wire the CT terminal and output terminal (such as heater power supply), set the CT * target connection setting (CI *) and CT 1 abnormality current value setting (Ct 1), and establish the control effective.
■ Calculation of the CT 1 abnormal current value setting Detection current to be set is calculated with the following equation as an indication: Current normal value + current at heater disconnection 2 ∴ CT 1 abnormal current value setting value = Note Take care that the current in a multiplication factor of N flows when the load wire is wound around CT N times due to too small a measurement current. Sixty amperes or 6 times the actual current of 10 A flows when the load wire is wound around CT 6 times.
■ For 3-phase ■ Delta connection Example: Where 3 heaters of 200 V and 2 kW are used [When normal] Load Load Load To equipment CT input To equipment CT input Normal current is 17.3 A (≒√3 × 10 A) for each phase.
■ Star connection Example: Where 3 heaters of 200 V and 2 kW are used Load [When normal] Load Load To equipment CT input To equipment CT input Normal current is 5.8 A {≒10 A × (1/√3)} for each phase.
■ V connection Example: Where 2 heaters of 200 V and 2 kW are used [When normal] To equipment CT input Load Load To equipment CT input The current that flows in the target device for CT installation is 17.3 A (≒√3 × 10 A).
5.4.8 Position proportional control ■ What the position proportional control is • In the position proportional control, the temperature of the subject is controlled through adjusting the flow rate, which depends on the valve opening ratio. The valve opening ratio is controlled by open or close signal that is output for the valve, where an operating amount is calculated by the PID control, taking into account the valve motor stroke time.
5.4.9 Concurrent temperature ascent function ■ What the concurrent temperature ascent is • When a concurrent temperature ascent control is executed for multiple channels using the RS-485 communication function, a target value can be reached for each channel at the same clock time, disregarding characteristics of each channel through assigning master or slave to the channels.
5.5 Explanation of the program run function ■ The digital controller TTM-200 Series can provide a simple program controller. This chapter explains the program run of TTM-200 Series. • A program run of this product is established by automatically controlling “bank function” and “program step function.” The process flow for establishing a program run is described below.
5.5.1 Operation flow of the program run ■ Digital controller: This section explains operation process of the program run using TTM-200. To perform a program run, the SET 20, SET 21 and SET 22 parameters must be set. ■ The setting content is as follows: Set a parameter desired to change with setting value in the SET 20 bank setting for each step. For the setting, select a parameter requiring to be switched during a program run from SETs 1 to 17.
5.5.2 SET 21 program function setting ■ The SET 21 program function setting is for setting operating method of a program run. Set the setting values for the following: “program run mode,” “power failure compensation range,” “time unit,” “WAIT range” and “Program run start/stop.” The flowchart below is for “SET 21 program function setting.” Note Note that some screens do not appear depending on setting values. Characters indicated in parentheses are those displayed on a screen.
*1: Operating type setting (C/P) Set “operating method.” Setting range Initial value: 0 in constant value run mode 0: Constant value run mode (program run mode OFF) 1: Program run mode (program run mode ON) *2: Program rum mode setting (PGMd) Set “return operating method” and “operation method after program run” in case of power failure during a program run.
*4: Time unit setting (H/MP) Set “time unit” and “step transfer condition (time countdown condition)” of a step.
5.5.3 SET 21 program function setting screen ■ The program function setting screen is shown below. 25 25 PV value (present value) SV value (setting value) Hold MODE key pressed for 2 seconds Input 1 setting screen SET01 INP1 Press the key or key several times. Program function setting mode SET21 PGF Press MODE key. Hold MODE key pressed for 2 seconds Operating type setting C/P 0 No. Setting range 0 Constant value run mode (initial value) 1 Program run mode Press MODE key.
5.5.4 SET 22 program setting ■ Set a pattern (program) of the program run in the SET 22 program setting. [Setting items] • Set “number-of-use-steps” of the program. • Set “bank designation,” “step SV value” and “step time” of each step. • Set “repetitive start step,” “repetitive end step” and “execution count.” [Setting flow] The flowchart below is for “SET 21 program function setting.” Characters indicated in parentheses are those displayed on a screen.
*5: Bank setting (St*bK) Switchover is made for each step of a program. “Bank No.” can be designated. Setting range: St*bK = 0 to 7 (The range depends on SET 4 bANKH.) Initial value: St* bK = 0 (* = 1 to 8) Note The symbol “*” of the parameter setting display “St*bK” indicates “step No.” (The range depends on SET 22 StEPN.) Note Effective only during a program run Note When the bank automatic switching function is used (SET 23 BAF 1), no display appears.
5.5.5 SET 22 program setting screen ■ The program setting screen is shown below. 25 25 PV value (present value) SV value (setting value) Hold MODE key pressed for 2 seconds Input 1 setting screen SET01 INP1 SET22 PROG * When C/P 0, the setting SET 22 is not displayed. Therefore, all screens thereafter up to RUNP do not appear. Press MODE key. Number-of-use-step setting STEPN 8 Press MODE key. Step designation bank setting Press MODE key. Step SV setting SV1 0 Press MODE key.
5.5.6 Explanation of the screen display and operation of a program run ■ Switching the run screen Switching between “constant value run,” in which no program is used, and “program run,” in which a program automatically executes a run, is performed with “SET 21 C/P.” This section describes “program run mode.” PV display section PV SV display section Auxiliary display section The diagram below shows that the display varies depending on the difference of run modes.
■ Regarding operation and display of a program run The diagram below shows “screen display during a program run.” The screens are categorized into “before run,” “run in process” and “run end” depending on run status.
■ Regarding the “program run mode” operation list table “Program run” is categorized into “before run,” “run in process” and “run end” depending on run status, for which the operable keys vary. “Operation list table” indicates key operations corresponding to the status. “In-stop” indicates before a run, “run in process” a run in process and “After-end” a run ended. The INDEX ① to ⑯ in the diagram corresponds to “operation and display of a program run” in the previous page.
< Operation list table (2/3) > INDEX ⑤ Screen Step time monitor Run status Before run ⑥ Run in process ⑦ ⑧ Key operation Run end Program run start/stop screen ⑨ Run in process ⑩ Note 48-7009-E Before run Run end *1: *2: *3: *4: Type Behavior Operation method MODE Prolonged press of 2 seconds To the setting mode MODE Depression To the program run start/stop screen FU1-5 Depression Follows the function key setting.

5.5.7 Complementary explanation of the program run ■ Regarding the time unit setting (H/MP) Parameters for “step time” and “countdown condition” are provided in the program settings. “Countdown condition” can be selected with a setting value. The example below is for STEPn 5 (step number 5). The total time of each step is referred to as “step time” and a status terminated with temperature variation as “soak time.
If an increase rate of PV is larger than that of SV, the countdown begins after SV reaches SV3. SV3 Wait range PV SV Step time Soak time 1 Soak time 2 ① ② ③ < Countdown condition > Step time (H/MP 0 or 3): The program steps proceed in accordance with the time set for each step. Time countdown begins regardless of the statuses of PV and SV values and a step proceeds to the next one upon set time elapsed.
■ Regarding the ramp function The ramp function can be used even during a program run. To use the function, first set a RMP for either one of the banks [SET 20 bNK01 to 16]. Next, set the RMP value for each bank. The function is executed with the RMP value designated by [SET 22 St*bK] during the program setting. Note Note that the ramp function is ineffective if the step time [H/MP 0 or 3] is set. Note In the case of ramp setting (RMP = 0), the ramp function does not work.
■ Regarding the time signal output function A signal of time signal can be output for each step during a program run. Timers 1 to 3 for step time are usable as is, as a timer independent from those is used for the signal. Note The function is active only during a run. Timer operation is also halted during In-stop or After-end. Note The timer is reset at step switchover and END transition. Note Timer operation is skipped to make transition with a step time if a time longer than the step time is set.
This section introduces the timer function. Timer behavior is determined by defining the following parameters: timer function setting [tMF 1 to tMF 3], unit setting [H/M 1 to H/M 3], SV start allowable range setting [tSV 1 to tSV 3], On delay timer [oNt 1 to oNt 3], Off delay timer [oFt 1 to oFt 3], repetition count setting [RUN 1 to RUN 3], etc.
Set the ON delay timer, OFF delay timer and repeat count for a timer. Set the ON delay timer for Timers 1 to 3 using [oNt 1 to oNt 3]. Set the OFF delay timer for Timers 1 to 3 using [oFt 1 to oFt 3]. Set the repetition count for Timers 1 to 3 using [RUN 1 to RUN 3].
■ Regarding repetitive run A repetitive run of a designated step can be executed during a program run. Any step (as a whole or part) of program steps set in SET 22 can be repeated. The diagram below shows an example of using this function where the steps 2 and 3 of total 4 steps are repeated 3 times. A program run begins. A program run ends.
■ Regarding switchover of the input types If input 1 type [INP 1] is set in a bank, an operation of switching the input type can be executed during a program run by using the “step* designated bank setting [St*bK] ” function. Note Note that the input type must be selected from the same group as listed below. Input types from different groups should not be mixed. Otherwise, switching the decimal point malfunctions. Input 1 type in Group A Setting No.
■ The diagram below shows an example of a program run with StEPN 8.
5.6 Explanation of the bank automatic switching function ■ Regarding the bank automatic switching function The bank function can be automatically switched for each temperature. Setting control parameters for each temperature beforehand enables realization of optimization and an accurate control. As parameters unrelated to control can also be set similarly to the case of the normal bank function, application for each temperature is possible for such functions as the timer and event functions.
5.6.1 Bank automatic switching setting ■ The operation procedure of bank automatic switching is explained below. Switching conditions are set in the SET 23 parameter. The bank switching method (input, switching sensitivity, etc.) and switching threshold are set. Parameters desiring to be switched are set for each threshold in the SET 20 bank setting. For details of the bank setting method, see Section 5.4.4 Bank function (P5-28 to 30). The diagram below shows the procedure of the SET 23 parameter setting.
*1: Bank automatic switching function selection (bAF) Set the bank automatic switching ON/OFF. Setting range Initial value: 0 Bank automatic switching run OFF 0: Bank automatic switching run OFF 1: Bank automatic switching run ON *2: Bank automatic switching source setting (bAS) Select an input source. The bank is switched in accordance with the input of the source selected. Setting range Initial value: 0 Select a SV value 0: Select a SV value {only local and remote (only option Y)}.
5.6.2 SET 23 bank automatic switching function setting mode setting screen ■ The bank automatic switching function setting screen is shown below: 25 25 PV value (present value) SV value (setting value) Hold MODE key pressed for 2 seconds Input 1 setting screen SET01 INP1 Press the key or key several times. Setting the bank automatic switching function setting mode SET23 ZBNK Press MODE key. Hold MODE key pressed for 2 seconds Bank automatic switching function selection BAF 0 No.
5.6.3 Complementary explanation of the bank automatic switching function Regarding the zone threshold* setting [PM1 to PM7]: If all seven points at most are set with different values one another, eight zones can be established for each temperature allowing eight banks to be used. The setting range is from SLL to SLH. If all seven points are set to SLH, the threshold is integrated into one zone to provide the maximum value (applicable only for the bank 0). The initial value is set to this status.
■ Setting example of the bank automatic switching function setting mode (2 banks used) The example shows a threshold for auto switching to be of one point. In this case, Bank 0 and Bank 1 are used.
■ Setting example 3: Bank automatic switching function setting mode (when the program run function is also used) This example shows use of both the program run and eight banks for the bank automatic switching function. The “designated bank” setting for a program run is ineffective in a bank automatic switching function run. The bank designation according to the bank automatic switching function is always prioritized over others.
■ Regarding the “bank function” priority If multiple settings are set for the bank switching designation, bank switching is applied from of a function with a higher priority. The following applies (“1” is of the highest priority). 1. “Bank automatic switching function” SET 23 [PM*] zone threshold* setting (“*”: Zone No.) 2. “Program run” SET 22 [St*bK] step* designated bank setting (“*”: Step No.) 3. “Switching with DI” SET 13 DIF **** (when “*” 1) 4.
■ Regarding switchover of the input types If input 1 type [INP 1] is set in a bank, an operation of switching the input type can be executed during a program run by using the bank automatic switching function. Note Note that the input type must be selected from the same group as listed below. Input types from different groups should not be mixed. Otherwise, switching the decimal point malfunctions. Input 1 type in Group A Setting No.

Setting example: Fluctuation or missing value of PV may be caused when the remote SV input is set to the input type of 4 - 20 mA, FSL 2 to -19999 digits and FSH 21 to 29999 digits. (2) Take care that setting values for FSH 2 and FSL 2 can be the same.
PV compensation zero setting: PV (measurement value) for the remote SV input is added by the compensation value. Setting example: Where PV of the equipment is displayed for 90°C and the actual temperature is 100°C, and the display is to be compensated to 100°C, using the PV compensation zero setting. The display after PV compensation is 100°C = 90°C (before PV compensation) + 10°C.
