The Fuzzy Logic technology enables a process to reach a predetermined set point in the shortest time, with the minimum of overshoot during power-up or external load disturbance. The units are housed in a / DIN case, measuring mm x mm with mm behind panel depth. The units feature three touch keys to select the various control and input parameters. Using a unique function, you can put at most parameters in front of user menu by using SEL to SEL contained in the setup menu. This is particularly useful to OEM's as it is easy to configure menu to suit the specific application. FDC- is powered by - or - VDC / AC supply, incorporating a amp. control relay output and dual amp. alarm relays output as standard whereby second alarm can be exceptionally configured into second output for cooling purpose or dwell timer. Alternative output options include SSR drive, triac, - ma and - volts. FDC- is fully programmable for PT, thermocouple types J, K, T, E, B, R, S, N, L, - ma, -ma and voltage signal input, with no need to modify the unit. The input signals are digitized by using a -bit A to D converter. Its fast sampling rate allows the FDC- to control fast processes such as pressure and flow. Self tune is incorporated. The self- tune can be used to optimize the control parameters as soon as undesired control result is observed. Unlike auto-tune, Self-tune will produce less disturbance to the process during tuning, and can be used any time. The function of Fuzzy Logic is to adjust PID parameters internally in order to make manipulation output value MV more flexible and adaptive to various processes. PID + Fuzzy Control has been proven to be an efficient method to improve the control stability as shown by the comparison curves below Temperature PID control when properly tuned PID + Fuzzy control Set point Warm Up Load Disturbance Figure.

15 Chapter Installation Dangerous voltages capable of causing death are sometimes present in this instrument. Before installation or beginning any troubleshooting procedures the power to all equipment must be switched off and isolated. Units suspected of being faulty must be disconnected and removed to a properly equipped workshop for testing and repair. Component replacement To minimize the possibility of fire or shock hazards, do not expose this instrument to rain or excessive moisture. Do not use this instrument in areas under hazardous conditions such as excessive shock, vibration, dirt, moisture, corrosive gases or oil. The ambient temperature of the areas should not exceed the maximum rating Unpacking Upon receipt of the shipment remove the unit from the carton and inspect the unit for shipping damage. If any damage due to transit, report and claim with the carrier. Write down the model number, serial number, and date code for future reference when corresponding with our service center. The serial number (S/N) and date code (D/C) are labeled on the box and the housing of control. Mounting Make panel cutout to dimension shown in Figure.. Take both mounting clamps away and insert the controller into panel cutout. Install the mounting clamps back.

16 Wiring Precautions Before wiring, verify the label for correct model number and options. Switch off the power while checking. Care must be taken to ensure that maximum voltage rating specified on the label are not exceeded. It is recommended that power of these units to be protected by fuses or circuit breakers rated at the minimum value possible. All units should be installed inside a suitably grounded metal enclosure to prevent live parts being accessible from human hands and metal tools. All wiring must conform to appropriate standards of good practice and local codes and regulations. Wiring must be suitable for voltage, current, and temperature rating of the system. Beware not to over-tighten the terminal screws. Unused control terminals should not be used as jumper points as they may be internally connected, causing damage to the unit. Verify that the ratings of the output devices and the inputs as specified in Chapter are not exceeded. Electric power in industrial environments contains a certain amount of noise in the form of transient voltage and spikes. This electrical noise can enter and adversely affect the operation of microprocessor-based controls. For this reason we strongly recommend the use of shielded thermocouple extension wire which connects the sensor to the controller. This wire is a twisted-pair construction with foil wrap and drain wire. The drain wire is to be attached to ground at one end only..mm max..mm min. Figure.

17 Power Wiring The controller is supplied to operate at - VAC / VDC or -VAC.Check that the installation voltage corresponds with the power rating indicated on the product label before connecting power to the controller. Fuse ~ VAC or ~ VAC / VDC Figure. Power Supply Connections This equipment is designed for installation in an enclosure which provides adequate protection against electric shock. The enclosure must be connected to earth ground. Local requirements regarding electrical installation should be rigidly observed. Consideration should be given to prevent from unauthorized person access to the power terminals. Sensor Installation Guidelines Proper sensor installation can eliminate many problems in a control system. The probe should be placed so that it can detect any temperature change with minimal thermal lag. In a process that requires fairly constant heat output, the probe should be placed closed to the heater. In a process where the heat demand is variable, the probe should be closed to the work area. Some experiments with probe location are often required to find this optimum position. In a liquid process, addition of a stirrer will help to eliminate thermal lag. Since the thermocouple is basically a point measuring device, placing more than one thermocouple in parallel can provide an average temperature readout and produce better results in most air heated processes. Proper sensor type is also a very important factor to obtain precise measurements. The sensor must have the correct temperature range to meet the process requirements. In special processes the sensor might need to have different requirements such as leak-proof, anti-vibration, antiseptic, etc. Standard sensor limits of error are Adegrees F (A degrees C ) or.% of sensed temperature (half that for special ) plus drift caused by improper protection or an over-temperature occurrence. This error is far greater than controller error and cannot be corrected on the sensor except by proper UMA

18 ON ON Thermocouple Input Wiring Thermocouple input connections are shown in Figure.. The correct type of thermocouple extension lead-wire or compensating cable must be used for the e n t i r e distance between the controller and the thermocouple, ensuring that the correct If the length of thermocouple plus the extension wire is too long, it may affect the temperature measurement. A ohms K type or a ohms J type thermocouple lead resistance will produce degree C temperature error approximately. DIP Switch + Figure. Thermocouple Input Wiring Thermocouple RTD Input Wiring RTD connection are shown in Figure., with the compensating lead connected to terminal. For two-wire RTD inputs, terminals and should be linked. The three-wire RTD offers the capability of lead resistance compensation provided that Two-wire RTD should be avoided, if possible, for the purpose of accuracy.

Adjust TIME in minutes AMD ( if AFN=TIMR ) or AMD ( if AFN=TIMR ) is ignored in this case. If a form B relay is required for dwell timer, then order form B alarm and configure AFN. Form B relay is not available for alarm. Manual Control The manual control may be used for the following purposes ( ) To test the process characteristics to obtain a step response as well as an impulse response and use these data for tuning a controller. () To use manual control instead of a close loop control as the sensor fails or the controller's A-D converter fails. NOTE that a bumpless transfer can not be used for a longer time. See section -. ( ) In certain applications it is desirable to supply a process with a constant demand. Operation Press until ( Hand Control ) appears on the display. Press for seconds then the upper display will begin to flash and the lower display will show. The controller now enters the manual control mode. Pressing the lower display will show and alternately where indicates output ( or heating ) control variable value MV and indicates output ( or cooling ) control variable value MV. Now you can use up-down key to adjust the percentage values for H or C. The controller performs open loop control as long as it stays in manual control mode. The H value is exported to output ( OUT ) and C value is exported to output provided that OUT is performing cooling function ( ie. OUT selects COOL ). Exit Manual Control To press keys the controller will revert to its previous operating mode ( may be a failure mode or normal control mode ). Means MV=. % for OUT ( or Heating ) Means MV=. % for OUT ( or Cooling ) Exception If OUT is configured as ON-OFF control ( ie. PB= if PB is assigned or PB= if PB is assigned by event input ), the controller will never perform manual control mode. UMA

Signal Conditioner DC Power Supply Three types of isolated DC power supply are available to supply an external transmitter or sensor. These are V rated at ma, V rated at ma and V rated at ma. The DC voltage is delivered to the output terminals. Two-line Transmitter Set OUT = DC Power Supply ma Figure. DC Power Supply Applications Caution Don't use the DC power supply beyond its rating current to avoid damage. Purchase a correct voltage to suit your external devices. See ordering code in section -.

28 Bumpless Transfer The bumpless transfer function is available for output and output ( provided Bumpless Transfer Setup that OUT is configured as COOL ).. OFT = BPLS. OFT = BPLS Bumpless Transfer is enabled by selecting BPLS for OFT and/or OFT and activated as one of the following cases occurs Bumpless Transfer Occurs as. Power starts ( within. seconds ).. Power Starts ( within. seconds ). The controller enters the failure mode. See section - for failure mode. Failure mode is activated descriptions.. Manual mode is activated. The controller enters the manual mode. See section - for manual mode. Calibration mode is activated descriptions.. The controller enters the calibration mode. See Chapter for calibration mode descriptions. As the bumpless transfer is activated, the controller will transfer to open-loop control and uses the previous averaging value of MV and MV to continue control. Without Bumpless Transfer Set point PV Power interrupted Large deviation Sensor break Time Figure. Benefits of Bumpless Transfer Since the hardware and software need time to be initialized, the control is abnormal as the power is recovered and results in a large disturbance to the process. During the sensor breaks, the process loses power. With Bumpless Transfer Set point PV Power interrupted Sensor break Small deviation Load varies Time After bumpless transfer configured, the correct control variable is applied immediately as the power is recovered, the disturbance is small. During the sensor breaks, the controller continues to control by using its previous value. If the load doesn't change, the process will remain stable. Thereafter, once the load changes, the process may run away. Therefore, you should not rely on a bumpless transfer for a longer time. For fail safe reason, an additional alarm should be used to announce the operator when the system fails. For example, a Sensor Break Alarm, if configured, will switch to failure state and announces the operator to use manual control or take a proper security action when the system enters failure mode. Warning After system fails, never depend on bumpless transfer for a long time, otherwise it might cause a problem to the system to run away. UMA

29 Self Tuning The Self-tuning which is designed by using an innovative algorithm provides an alternative option for tuning the controller. It is activated as soon as SELF is selected with YES. When Self-tuning is working, the controller will change its working PID values and compares the process behavior with previous cycle. If the new PID values achieve a better control, then changing the next PID values in the same direction, otherwise, changing the next PID values in reverse direction. When an optimal condition is obtained, the optimal PID values will be stored in PB, TI, TD or PB, TI, TD which is determined by Event Input conditions. When Self-tuning is completed, the value of SELF will be changed from YES to NONE to disable self-tuning function. When the Self-tuning is enabled, the control variables are tuned slowly so that the disturbance to the process is less than auto-tuning. Usually, the Selftuning will perform successfully with no need to apply additional auto- Self-tune Menu or Default SELF=NONE Selects Disable Self-tuning Enable Self-tuning Exceptions The Self-tuning will be disabled as soon as one of the following conditions occurs. SELF is selected with NONE.. The controller is used for on-off control, that is PB=.. The controller is used for manual reset, that is TI=.. The controller is under loop break condition.. The controller is under failure mode (e.g. sensor break).. The controller is under manual control mode.. The controller is under sleep mode.. The controller is being calibrated. If the self-tuning is enabled, the auto-tuning can still be used any time. The self-tuning will use the auto-tuning results for its initial values. Benefits of Self-tuning. Unlike auto-tuning, Self-tuning will produce less disturbance to the. process. Unlike auto-tuning, Self-tuning doesn't change control mode during tuning. period. It always performs PID control. Changing set point during Self-tuning is allowable. Hence, Self-tuning can be used for ramping set point control as well as remote set point control where the set point is changed from time to time. Benefits of Self-tune. Less disturbance to the process.. Perform PID control during tuning period.. Available for ramping set point control and remote set point control. Operation The parameter SELF is contained in setup menu. Refer to Section - to obtain SELF for initiating a self-tuning. UMA

30 Auto Tuning The auto-tuning process is performed at set point. The process will oscillate around the set point during tuning process. Set a set point to a lower value if overshooting beyond the normal process value is likely to cause damage. The auto-tuning is applied in cases of Initial setup for a new process The set point is changed substantially from the previous auto-tuning value The control result is unsatisfactory Operation. The system has been installed normally.. Use the default values for PID before tuning. The default values are PB=PB=. F TI=TI= sec, TD=TD=. sec, Of course, you can use other reasonable values for PID before tuning according to your previous experiences. But don't use a zero value for PB and TI or PB and TI, otherwise, the auto-tuning program will be disabled.. Set the set point to a normal operating value or a lower value if overshooting beyond the normal process value is likely to cause damage.. Press until appears on the display. Applicable Conditions PB=, TI= if PB,TI,TD assigned PB=, TI=, if PB, TI, TD assigned. Press for at least seconds. The upper display will begin to flash and the auto-tuning procedure is beginning. NOTE Any of the ramping function, remote set point or pump function, if used, will be disabled once auto-tuning is proceeding. Procedures The auto-tuning can be applied either as the process is warming up ( Cold Start ) or as the process has been in steady state ( Warm Start ). See Figure.. If the auto-tuning begins apart from the set point ( Cold Start ), the unit enters Warm-up cycle. As the process reaches the set point value, the unit enters waiting cycle. The waiting cycle elapses a double integral time ( TI or TI, dependent on the selection, ) then it enters a learning cycle. The double integral time is introduced to allow the process to reach a stable state. Before learning cycle, the unit performs pre-tune function with a PID control. While in learning cycle the unit performs post-tune function with an ON-OFF control. Learning cycle is used to test the characteristics of the process. The data are measured and used to determine the optimal PID values. At the end of the two successive ON-OFF cycles the PID values are obtained and automatically stored in the nonvolatile memory. After the auto-tuning procedures are completed, the process display will cease to flash and the unit revert to PID control by using its new PID values. During pre-tune stage the PID values will be modified if any unstable phenomenon which is caused by incorrect PID values is detected. Without pre-tune stage, like other conventional controller, the tuning result will be strongly related to the time when the auto-tuning is applied. Hence different values will be obtained every time as autotuning is completed without pre-tune. It is particularly true when the auto-tuning are applied by using cold start and warm start. Pre-tune Function Advantage Consistent tuning results can be obtained UMA

Afterward the procedures are same as that described for cold start. Auto-Tuning Error If auto-tuning fails an ATER message will appear on the upper display in cases of If PB exceeds ( PU,. LF or. LC ). or if TI exceeds seconds. or if set point is changed during auto-tuning procedure. or if event input state is changed so that set point value is changed. Auto-Tuning Error Solutions to.

32 Manual Tuning In certain applications ( very few ) using both self-tuning and auto-tuning to tune a process may be inadequate for the control requirement, then you can try manual tuning. Connect the controller to the process and perform the procedures according to the flow chart shown in the following diagram. Use initial PID values to control the process Figure. Manual Tuning Procedure Wait and Examine the Process Wait and Examine the Process No Is steady state reached? No Is steady state reached? Yes Yes Does the process oscillate?

So the above manual tuning procedures will take from minutes to hours to obtain optimal PID values. UMA
