Z SERIES DATA SHEET FUZZY CONTROLLER X (48) 48mm) PYX4 The PYX is a state-the-art temperature controller offering enhanced control through the use of fuzzy logic. By employing fuzzy logic the PYX virtually eliminates system overshoot and effectively supresses fluctuation of the process variable due to external disturbances. Fuzzy logic control is the technology of tomorrow offered today. This controller features universal input circuitry and can accept signals from all thermocouple types, RTD's, and current/voltage sources. As well, the PYX-4 gives you the flexibility of choosing such available features as RS-485 communications, analog retransmission, dual output, heater break alarm, and loop break alarm, to name a few. The PYX-4 is the world's first 1/16 DIN fuzzy logic controller featuring high performance/cost ratio. FEATURES 1. Industry-first incorporation of fuzzy control in 48 mmsquare controller An improved response characteristic of controller is ensured thanks to the fuzzy control exercised while detecting an overshoot or a difference from the set temperature value due to a large disturbance. (Time taken for returning to the set value can be shortened and temperature variation width can be narrowed.) 2. Universal input This means that a signal controller can respond to 11 kinds of thermocouples, resistance bulbs and voltage/current inputs. 3. Communication function comprised despite small size (option) Because the general-purpose interface (RS-485) is mountable, a centralized monitoring/setting system aided by a personal computer can readily be configured. Upon building up a system, the size of this controller as small as 48 mm square is helpful for saving on the equipment installation area. The communication protocol conforms either the Fuji Electric CC data line or Modbus® RTU. 4. Auto/Manual Change auto-mode to manual-mode and manual operation can be done using front panel keys. 5. A wide variety of optional functions (1) A0 re-transmission (1 point) A0 is recordable in connection with Fuji's microjet recorder PHA/PHC. (2) Programmable alarm (2 points max.) 2 kinds of alarm action can be registered selected from 16 kinds. (3) Dual output Dual control of heating and cooling operations are allowed (In this case, communication, A0 and HB (heater break) functions cannot be added). (4) Heater break alarm Use ALM1 or ALM2 output for heater break alarm (with heater current message-function) (5) Ramp/soak function 4 ramp/soak-pair patterns are registrable. (6) External DI function (1 point) SV (setting value) can be changed a predetermined value according to external command input (DI). (7) Remote SV SV (setting value) can be controlled by external 1 to 5V DC analog input. 6. UL, C-UL approval Modbus® is a registered trademark of Gould Modicon.

It is understandable that the overshoot due to a change of set value has been suppressed in fuzzy control. FUZZY 100.0 80.0 60.0 % 40.0 20.0 PID (4) Auto-tuning PID parameters are automatically set by controller's measurement and operation.

This device allows maximum of 4 ramp soak programs. This first ramp starts at the value measured immediately before the program is executed (PV). Set point Set point 3 Set point 2 Set point 1 Set point 4 PV First First ramp soak Second soak Second ramp Third Third ramp soak Fourth ramp Fourth soak OFF 0% ON-OFF action Remarks: (1) Once auto-tuning has been made, PID parameter values are retained despite power-off operation. Therefore, autotuning need not be repeated for the subsequent operations. (2) During auto-tuning, control output corresponds to ON/OFF action. This may cause PV to change widely depending on process. If such a change is unallowable, auto-tuning should not be used. (3) Do not use the auto-tuning function for a process having a quick response, such as pressure control, flow control, etc. (5) Anti-reset Windup (ARW)(*) Time Control output (MV) 100% TM1R TM1S TM2S TM3S TM2R TM3R TM4R TM4S Ramp : Region in which the SP changes toward the target value.

During autotuning, output on the cooling side remains turned off. After autotuning, both heating and cooling operations are performed according to the same PID values. (2) ID set value is the same between heating and cooling sides. Individual setting cannot be accepted. (7) Heater break alarm (option) • Use the current transformer (CT) specified by Fuji. • Heater break is detected only when single-phase heater is used. • Heater break alarm is not available when controlling the heater by thyristor phase-angle control method. • [alarm detection point] and [Heater current] are registered using of front key. 8 OUTLINE DIAGRAM (Unit:mm) 48 5.5 115.0 SEL Flush mounting panel cutout 45 +0.5 -0 CAUTION OF SAFETY First of all, read this "Caution on Safety" carefully, and then use the instrument in the correct way. The cautionary descriptions listed here contain important information about safety, so they should always be observed. Those safety precautions are classilied in 2 ranks, WARNING and CAUTION. The following shows the meaning of WARNING and CAUTION. Wrong handling may cause a dangerous situation in which there is 2 possibility of death or heavy injury. Wrong handling may cause a dangerous situation in which there is a possibility of injury or physical damage. WARNING CAUTION WARNING For the safe operation of the controller, where the temperature probe is to be installed into an environment where voltages exceed 50 VDC, it is essential that reinforced isolation or basic isolation and earth is maintained between all connections to the rear of the temperature controller, and that supplementary isolation is required for the alarm outputs. The outputs from the controller are all less than 50 VDC. When wiring the power supply terminal, use vinyl insulated 600 volt cable or equivalent. A switch breaking both poles of the mains supply should be installed together with a fuse with a rating of 250volt 1Amp. The fuse should be installed between the mains switch and the controller. The level of insulation provided by the temperature controller is; MAINS=BASIC HEATER=BASIC INPUTS=BASIC Prior to operation of the installed system the wiring should be checked to ensure that the required levels of insulation have been provided. 45 +0.5 -0 44.8 48 9 PYX4 s TERMINAL WIRING (1) Normally open SPST contact (Control output 1) Digital input Re-transmission (AO) 11 12 11 + 12 (Control output 2) SSR drive output 11 + 12 11 12 HB current input RS-485 transmission TRX2 11 Remote SV input TRX1 12 11 12 Relay output (Control output 1) Alarm 2 output or HB alarm Alarm 1 output or HB alarm Common Power supply 100 to 240V AC 50/60Hz 6 1 2 3 4 5 11 12 6 7 8 9 10 + 8 9 10 9 10 + Relay output 4 to 20mA DC - 6 + SSR drive - 7 7 [Process input] 9 10 Thermocouple (2) SPDT (Control output 1) Digital input Re-transmission (AO) 11 12 11 + 12 Resistance 1 to 5V DC bulb 4 to 20mA DC (Control output 2) SSR drive output 11 + 12 11 12 HB current input RS-485 transmission TRX2 11 Remote SV input TRX1 12 11 12 Relay output (Control output 1) (normally close) Alarm 1 output or HB alarm Common Power supply 100 to 240V AC 50/60Hz 1 2 3 4 5 11 12 6 7 8 9 10 (Control output 1) Relay output + 8 9 10 9 10 [Process input] 9 10 Thermocouple ORDERING OF CURRENT TRANSFORMER Current transformer for heater break Specification : For 20 to 50A Ordering code : CTL-12-S36-8F 30 φ2.36 Resistance 1 to 5V DC bulb 4 to 20mA DC Specification : For 1 to 30A Ordering code : CTL-6-SF 21 2.8 9 φ5.8 40 10.5 φ12 30 40 3 25 10 φ3.5 M3 depth 4 30 40 7.5 Caution on Safety *Before using this product, be sure to read its instruction manual in advance.
