Push the adapter up to the back of the panel ensuring that the controller is pushed all the way in, removing any gap between the Controller, panel, and adapter. Finally, use the two screws on the adapter to secure the unit in place. To mount the E5GN so that it is waterproof, insert the waterproof packing onto the E5GN. When two or more E5GN Controllers are mounted, make sure that the surrounding temperature does not exceed the allowable operating temperature given in the specifications. Wiring Terminals * The voltage output (control output) is not electrically insulated from the internal circuits. When using a grounding thermocouple, do not connect the control output terminals to the ground. If the control output terminals are connected to the ground, errors will occur in the measured temperature values as a result of leakage current. * Standard insulation is applied to the power supply I/O sections. If reinforced insulation is required, connect the input and output terminals to a device without any exposed current-carrying parts or to a device with standard insulation suitable for the maximum operating voltage of the power supply I/O section.

E5AN/E5EN/E5CN/E5GN E5AN/E5EN/E5CN/E5GN Fuzzy Self-tuning The fuzzy self-tuning (ST) is a function that automatically calculates an optimum PID constant depending on items to be controlled. Feature The Temperature Controller determines when to execute this fuzzy self-tuning. Functions SRT: Performs PID tuning according to the step response method when the SP is changed. Requirements for SRT Functionality The ST will be executed according to the step response method when the following conditions are satisfied when operation is started or when the SP is changed. When operation is started When SP is changed 1. The SP at the startup is different from the SP at the time the 1. The SP after change is different from the SP at the time the previous SRT was executed. (See note.) previous SRT was executed. (See note.) 2.

(It can be in the balanced state if no output is generated when the power is turned ON.) If the SP is changed while SRT is being executed and if SRT completion conditions are satisfied, no PID change will take place. Stabilization State Measured values remain in the stable range for a certain period of time. Balanced State Output is 0% for 60 seconds and measured values fluctuate within the width of the stable range. Temperature This inclination is referred to as R.

Before using the product under conditions which are not described here or applying the product to nuclear control systems, railroad systems, aviation systems, vehicles, combustion systems, medical equipment, amusement machines, safety equipment, and other systems, machines, and equipment that may have a serious influence on lives and property if used improperly, consult your OMRON representative. Make sure that the ratings and performance characteristics of the product are sufficient for the systems, machines, and equipment, and be sure to provide the systems, machines, and equipment with double safety mechanisms. Safety Precautions Definition of Precautionary Information ! DANGER Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. ! WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. ! Caution Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury, or property damage. WARNING Do not attempt to take any Temperature Controller apart while the power is being supplied. Doing so may result in electric shock. ! WARNING Do not touch any of the terminals or terminal blocks while the power is being supplied. Doing so may result in electric shock. ! WARNING Do not allow pieces of metal or wire cuttings to get inside the Temperature Controller. Failure to do so may result in malfunction, electric shock or fire. ! WARNING Do not attempt to disassemble, repair, or modify the Temperature Controller. Any attempt to do so may result in malfunction, fire, or electric shock. ! Caution Do not use the Temperature Controller in locations subject to flammable gases. Doing so may result in an explosion. ! Caution The switching capacity and switching conditions will have a great effect on the longevity of the output relays. Use the Temperature Controller within the rated load and do not use the Temperature Controller beyond the number of operations specified under electrical life. Using the Temperature Controller beyond its electrical life may result in contact welding or burning. ! Caution Do not use the Temperature Controller at loads greater than the rated value. Doing so may result in burning or other damage. ! Caution Use a power supply voltage within the specified range. Failure to do so may result in burning or other damage. ! 46 Caution Tighten the terminal screws to the following torques: E5AN, E5EN, E5CN: 0.74 to 0.90 NSm E5GN: Terminals 1 to 6: 0.23 to 0.25 NSm Terminals 7 to 9: 0.12 to 0.14 NSm Failure to tighten terminal screws to the correct torque may result in fire or malfunction. Caution Make settings for the Temperature Controller that are suitable for the controlled system. Failure to do so may cause unexpected operation resulting in damage to equipment or personal injury. ! Caution Prepare a circuit with an overheating prevention alarm and take other safety measures to ensure safe operation in the event of a malfunction. Loss of operational control due to malfunction may result in a serious accident. Operating Environment Precautions * * * * * * * * * * * Caution In order to ensure the safe operation, observe the following precautions. Do not use the Temperature Controller in the following places: * Locations exposed to radiated heat from heating devices * Locations subject to direct sunlight * Locations subject to temperatures or humidity outside the range specified in the specifications * Locations subject to condensation as the result of severe changes in temperature * Locations subject to corrosive or flammable gases * Locations subject to dust (especially iron dust) or salts * Locations subject to exposure to water, oil, or chemicals * Locations subject to shock or vibration Use and store the Temperature Controller within the rated temperature and humidity specified for each model. When two or more Temperature Controllers are mounted horizontally close to each other or vertically next to one another, the internal temperature will increase due to heat radiated by the Temperature Controllers and the service life will decrease. In such a case, forced cooling by fans or other means of air ventilation will be required to cool down the Temperature Controllers. When providing forced cooling, however, be careful not to cool down the terminal sections alone to avoid measurement errors. Allow enough space around the Temperature Controller to ensure proper heat dissipation. Do not block the ventilating holes. Check polarities and orientation when connecting terminals. Not doing so may result in malfunction. When wiring the E5AN, E5EN, or E5CN, use crimp terminals with the specified dimensions (M3.5, width 7.2 mm max.). When wiring the E5GN, use cables of a thickness AWG24 (0.205 mm2) to AWG14 (2.081 mm2) for terminals 1 to 6 and use cables of a thickness AWG28 (0.081 mm2) to AWG22 (0.326 mm2) for terminals 7 to 9. The exposed current-carrying part to be inserted into terminals must be 5 to 6 mm. Do not use empty terminals. To avoid inductive noise, keep the wiring for the Temperature Controller's terminal board away from power cables carry high voltages or large currents. Also, do not wire power lines together with or parallel to Temperature Controller wiring. Using shielded lines to separate pipes and ducts is recommended. Attach surge absorbers or noise filters to peripheral devices that may generate noise, such as inductance devices (e.g., motors, transformers, solenoids, magnetic coils etc.). If using a noise filter with the power supply, in addition to confirming the voltage and the current, mount the power supply as near as possible to the Temperature Controller. Set up the Temperature Controller, along with its power supply, as far away as possible from devices that generate strong, high-frequency waves (highfrequency welders, high-frequency machines etc.) and devices that generate surges. Set up the power supply so that the voltage will reach the rated voltage within 2 seconds after turning ON. Allow at least 30 minutes for the Temperature Controller to warm up. When using auto-tuning, turn ON power for the load (e.g., heater) at the same time as or before supplying power to the Temperature Controller. If power is turned ON for the Temperature Controller before turning ON power for the load, auto-tuning will ! Installation Precautions ! !

In order that power can be turned OFF in an emergency by the person operating the Temperature Controller, install the appropriate switches and circuit breakers and label them accordingly. With the E5AN, E5EN, or E5CN, when drawing out the Temperature Controller body, do not touch or apply excessive force. After the body is drawn out do not touch the terminals or electronic parts. When inserting, make sure that electronic parts do not come in contact with the case. When the terminal block for the E5GN is detached, do not touch or apply excessive force to any electronic parts. Use alcohol to clean the Temperature Controller. Do not use thinner or other solvent-based substances. Correct Use E5AN/E5EN/E5CN/E5GN When starting operation after the Temperature Controller has warmed up, turn OFF the power and then turn it ON again at the same time as turning ON power for the load. (Instead of turning the Temperature Controller OFF and ON again, switching from STOP mode to RUN mode can also be used in this case.) If the Temperature Controller is used close to radios, television sets or wireless devices it may affect reception. In the case of Temperature Controllers with alarm outputs, alarm output may not be generated properly when an abnormality occurs in the device. It is suggested that a separate alarm device be incorporated in the system. To ensure proper performance, parameters of the Temperature Controllers are set to default values before they are shipped. Change these parameters depending on actual applications. If left unchanged, the Temperature Controller will operate under the default settings. Service Life Crimp Terminal Connection Use the Temperature Controller within the following temperature and humidity ranges: Temperature: -10C to 55C (with no icing or condensation) Humidity: 25% to 85% When the Temperature Controller is installed inside a control panel, ensure that the temperature around the Temperature Controller, not the temperature around the control panel, does not exceed 55C. The service life of relays used for the control output or alarm output largely varies depending on switching conditions. Be sure to confirm their performance under actual operating conditions and do not use them beyond the allowable number of switchings. If they are used in a deteriorated condition, insulation between circuits may be damaged and, as a result, the Temperature Controller itself may be damaged or burnt. The service life of electronic devices such as Temperature Controllers is determined not only by the number of switchings of relays but also by the service life of internal electronic components. Component service life is affected by the ambient temperature: the higher the temperature becomes, the shorter the service life becomes and, the lower the temperature becomes, the longer the service life becomes. Therefore, the service life can be extended by lowering the temperature of the Temperature Controller using fans or other means of air ventilation. When providing forced cooling, however, be careful not to cool down the terminals sections alone to avoid measurement errors. Use crimp terminals that match M3.5 screws. M3.5 x 8 self-rising screws are used. E5AN/E5EN/E5CN 7.2 mm max. Be careful not to excessively tighten the terminals screws. Soldering Connection The self-rising screws provide easy soldering connection. Strip the lead wire by a length of 6 to 8 mm and properly treat the terminal tip. Measurement Accuracy When extending or connecting the thermocouple lead wire, be sure to use compensating wires that match the thermocouple types. When extending or connecting the lead wire of the platinum resistance thermometer, be sure to use wires that have low resistance. When wiring the platinum resistance thermometer to the Temperature Controller, keep the wire route as short as possible. Separate this wiring away from the power supply wiring and load wiring to avoid inductive or other forms of noise. Mount the Temperature Controller so that it is horizontally level. If the measurement accuracy is low, check that input shift has been set correctly. Waterproofing The degree of protection is as shown below. Sections without any specification on their degree of protection or those with IP_ 0 have not been waterproofed. Front panel: NEMA4 indoor use (equivalent to IP 66) Rear case: IP 20 Terminal section: IP 00 Operating Precautions It takes approximately four seconds for the outputs to turn ON from the moment the power is turned ON. Due consideration must be given to this time when incorporating Temperature Controllers in a sequence circuit. When using auto-tuning, supply power to the load (e.g., heater) at the same time as or before supplying power to the Temperature Controller. If power is turned ON for the Temperature Controller before turning ON power for the load, auto-tuning will not be performed properly and optimum control will not be achieved. 47 E5AN/E5EN/E5CN/E5GN E5AN/E5EN/E5CN/E5GN ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
