4 SAFETY INFORMATION Before using, please read this (SAFETY INFORMATION) and then use this controller. It is important that the instructions in this manual are followed when using this instrument. Please keep this manual for future reference. Precautions are classified in WARNING and CAUTION. WARNING CAUTION There is a possibility of death or heavy injury when handling in wrong way. There is a possibility of injury or physical damage when handling in wrong way. WARNING. Caution on wiring Use an external protection circuit if a fault in the control loop could possibly lead to a serious problem. This instrument do not have a switch for power and a fuse, so please set them if it is needed. (Fuse rating 50 V, 0.5 A). Power supply Use a rated voltage to prevent damage or trouble. To avoid electrical shock or damage, do not turn ON the power until the wiring is completed. 3. Prohibit use in gas atmosphere Do not use it at a place exposed to combustible or explosive gas. 4. Handling of unit To avoid malfunction, electrical shock or fire, this unit must not be disassembled or repaired. Do not touch the terminals to avoid electrical shock or malfunction. 5. Caution on maintenance Turn the power before mounting or removing the instrument. To ensure continuous and safe operation of the instrument, periodical maintenance is recommended. Some parts are limited in life. The warranty period is year only if using in the correct way. CAUTION. Caution on handling Do not install the instrument under any of the following conditions. The ambient temperature exceeds 0 ~ 50 The ambient humidity exceeds 45 ~ 85 % RH. A place where temperature changes suddenly or icing occurs. A place exposed to corrosive gas or combustible gas. Vibration or shock is likely to be transmitted to the instrument. A place exposed to water, oil, chemicals, steam, sunlight. A place exposed to much dust, salt or iron. A place with much inductive disturbance, static electricity, magnetism noise. A place where heat such as radiant heat stays. 4

5 . Installation Attach the brackets ( units) on the fixed halls and tighten with a screwdriver. Fixing torque is about 47 N. cm (.5 kg.cm) (Care should be taken not to tighten forcedly) 3. Caution on terminal connections To avoid induction noise to input wires seperate from the power and output wires. Keep input wires away from output wires and use shielded wires to earth. Use a compensating cable with thermocouple. For R.T.D input use a cable which is a small lead wire resistance and without resistance difference to 3 wires. If the wiring has noise, use the following step: connect a surge absorber to the conductor coil side if the conductors are connected to the load output, such as the relay contact output. (EX. For 0 V AC ENC 47D-05A) Use an insulating transformer with a noise filter when the power suppy has much noise. (EX. TDK brand ZMB R5- noise filter) Noise filter should be mounted on a panel which has been earthed and the wiring between the noise filter output and the instrument power terminals should be shorten. It is effective to use a twisted cable for power supply against noise. The heater power supply and the instrument power supply should be connected using the same power suppy when a heater break alarm. Time for preparation of contact output is required at power ON. When the output signal is used for an extenal interlock circuit, connect a delay relay. 4. For load circuit connection Use an extra relay when the frequency of operation is rather high. SSR output type is recommended. Electromagnetic switch : Proportional cycle time is Min. 30 sec SSR : Proportional cycle time is Min. sec Contact output life : Mechanical : 0 million times (no load) Electrical : 00 thousand times (rated load) SSR drive pulse voltage, 4 ~ 0 ma DC are not insulated with internal circuit. Use non-grounded sensor to R.T.D and thermocouple. 5. For waterproof (Waterproof type) The instrument has IP65. Use rubber packing when installing the instrument to panel. Please attach the rubber in correct way. 6. Caution on key operation / trouble If alarm function is not set correctly, alarm output can not be operated at a trouble point. Be sure to check the alarm operation. If the input cable is disconnected, the display shows. When replacing the sensor, please turn the power suppy. 7. Other Do not use organic solvents such as alcohol, benzine when cleaning. (Use neutral detergent) 5

Signal Name Description Condition Initial value Retransmission group Set retransmission mode Reference Retransmission type or Power for sensor Hight limit of retransmission Low limit of retransmission PV / SV / Output volume (MV) Power for sensor (SPS) Thermocouple / R.T.D : FR -H ~ FR- L DC voltage : SL -H ~ SL-L but, RET. H > RET.L Optional PV / SV PV COMMUNICATION PX series are equipped with 4 wire / wire half-duplex the RS485 / RS4 communication interfaces. Using the interfaces, communications are available with maximum 3 devices. Signal Name Description Condition Initial value Communication group Set communication mode RS485/RS4 Protocol Communication rate (B.P.S) Parity check PC.LINK(Set value:0) / PC.LINK SUM (Set value:) 600(SV:0) / 00(SV:) / 400(SV:) 4800(SV:3) / 9600(SV:4) NONE(SV:0) / EVEN(SV:) / ODD(SV:) 0 4 Stop bit bit (SV:) / bit (SV:) Optional Data length 7 bit (SV:7) / 8 bit (SV:8) (Except PC LINK :8) 8 Address ~ 99, maximum 3 devices Response time 0 ~ 0. response time = (handling time + response time) X 0 ms 0 6

27 HEATER BREAK ALARM GROUP Heater break alarm group consist of output dead band and current detection display mode and detects spots (to be ordered seperately: current transformer model CTL-6-S. measurement range : ~ 50 A). Signal Name Description Condition Initial value Heater break alarm group Set HBA mode Current setting mode of HBA / ~ 50 A Current setting mode of HBA / ~ 50 A Hysteresis setting mode HBA Hysteresis setting mode HBA Current measurement value of HBA Current measurement value of HBA EUS (0.0 ~ 00.0 %) EUS (0.0 ~ 00.0 %) Only display (0 ~ 50 A) Only display (0 ~ 50 A) : It is not indicated in PX7. (There is no HBA function in PX, PX3) Optional EUS (0.5 %) EUS (0.5 %) 3 REMOTE INPUT GROUP If selecting REMOTE in Control group, set value will be set by remote set. In remote condition, SV is changeable by front keys, but the controller is controlled by external set value. Do not change set value by remote in auto tuning. Signal Name Description Condition Initial value Remote group Set remote mode High limit voltage of remote input Low limit voltage of remote input,000 ~ 5,000 V but, R. INH > R. INL High limit on scale Low limit on scale Thermocouple : FR-H ~ FR-L DC voltage : SL-H ~ SL-L Decimal point is set by DP-P. Optional PV Filter / ~ 0 PV Bias EUS (-00.0 ~ 00.0 %) : Thermocouple, R.T.D input ( FR-H ), DC voltage ( SL-H ) : Thermocouple, R.T.D input ( FR-L ), DC voltage ( SL-L ) EUS : Range at an engineering unit in compliance with the span of an instrument.
