Note: Refer to page 19 for information on changes in comparison to previous models. Note: Refer to Precautions on page 21. Features Improved Functions for a Wider Range of Application Control Analog Values, such as Pressures, Flowrates, and Levels The new E5CN Series now also includes models that accept analog inputs, enabling control applications other than for temperature, including pressure, flowrate, level, humidity, and weight control. Note: E5CN-@L (Models with Analog Inputs) Voltage Outputs (to Drive SSRs) for Both Heating and Cooling Control. Can Be Used for Alarms to Provide Three Alarm Outputs. Voltage outputs can be used for both heating and cooling for Models with Two Control Outputs. Also, control output 2 can be set for use as an alarm output, to enable using up to three alarm outputs. Note: E5CN-@Q (Option Board) Faster Sampling at 250 ms The previous sampling time of 500 ms has been reduced by half to 250 ms. This enables the new E5CN to handle application requiring even greater response speed and accuracy. Three-phase Heater Burnout Detection A transfer output now makes it easy to connect to a recorder or PLC Analog I/O Unit. With Models with Three-phase Heater Burnout and SSR Failure Detection, two current transformers can be connected to detect both heater burnout and SSR failure at the same time, reducing costs because a separate heater burnout alarm device is not required. SSR failure detection can be used even with Models with Singlephase Heater Burnout Alarms. Note: E5CN-C@ (Models with Current Outputs) Note: E5CN-@HH@ (Option Board) Easy Connector to a Recorder Easy, Dependable, and Even Faster Easy Setting with 11-segment Displays The new E5CN features 11-segment displays to make text easier to read, eliminating the need to decode displays when trying to set parameters, as was necessary with previous temperature controllers. Multi-input Capability with One Controller Connect to either a thermocouple or platinum resistance thermometer with the same model. Model selection is simplified, stocks are reduced, and fewer maintenance parts are required. Easily See Status from a Distance with PV Display with Three-color Switching Function Setting Protection Indicator Informs Operator when Protection Is Enabled A special icon on the display panel lights to let the operator know when setting protection has been set.

No. ntlp) for common precautions. Precautions for Safe Use !CAUTION Do not touch any of the terminals while the power is being supplied. Doing so may occasionally result in minor electric shock. Do not allow pieces of metal or wire cuttings to get inside the Temperature Controller. Failure to do so may occasionally result in minor electric shock, fire, or damage to equipment. Do not use the Temperature Controller in locations subject to flammable or explosive gas. Doing so may occasionally result in minor injury due to explosion. Do not attempt to disassemble, modify, or repair the Temperature Controller or touch any internal components. Doing so may occasionally result in minor electric shock, fire, or damage to equipment. Caution: Danger of Electric Shock a) This Temperature Controller is UL-listed as an opentype process controller. Use it in a control panel structure so that fire will not leave the panel. b) When using two or more cutoff switches, turn OFF all switches so that no power is supplied to the Temperature Controller before maintenance or inspections. c) Signal inputs are SELV restricted circuits. (See note 1.) d) Caution: To reduce the danger of fire or electric shock, do not internally connect the outputs of different class 2 circuits. (See note 2.) If the output relay is used beyond its life expectancy, its contacts may occasionally become fused or burned. Always consider the actual application conditions and be sure to use the output relay within its rated load and electrical life expectancy. The life expectancy of the output relay varies considerably according to its switching capacity and operating conditions. Fire may occasionally occur if terminal screws become loose. Tighten the terminal screws using a torque between 0.74 and 0.90 N·m. Make settings for the Temperature Controller that are suitable for the controlled system. Failure to do so may result in unexpected operation occasionally resulting in damage to equipment or personal injury. Warning: To reduce the danger or electric shock or fire, use the Temperature Controller in an controlled environment relatively free from polluting materials. Take appropriate safety measures, such as installing a separate monitoring system, to ensure safe operation in the event of a malfunction of the Temperature Controller. Loss of operation control or alarm outputs due to malfunction may occasionally result in physical damage to the controlled system or equipment. Note: 1. An SELV circuit is one separated from the power supply with double insulation or reinforced insulation, that does not exceed 30 V r.m.s. and 42.4 V peak or 60 VDC. 2. A class 2 power supply is one tested and certified by UL as have the current and voltage of the secondary output restricted to specific levels. 1. Do not use the Temperature Controller in the following locations. • Locations exposed to radiated heat from heating devices • Locations subject to exposure to water or oil • Locations subject to direct sunlight • Locations subject to dust or corrosive gas (especially sulfide gas or ammonia gas). • Locations subject to severe temperature changes • Locations subject to icing or condensation • Locations subject vibration or strong shock 2. Use and store the Temperature Controller within the rated ambient temperature and humidity. 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, use forced cooling by fans or other means of air ventilation to cool down the Temperature Controllers. 3. Allow enough space around the Temperature Controller to ensure proper heat dissipation. Do not block the ventilating holes. 4. Be sure to wire terminals properly using the correct polarity. 5. Use crimp terminals with the specified dimensions (M3.5, width 7.2 mm max.). Use wires of a thickness of AWG24 (0.205 mm2) to AWG14 (2.081 mm2). The exposed current-carrying part to be inserted into terminals must be 5 to 6 mm. 6. Do not connect anything to unused terminals. 7. Allow as much space as possible between the Controller and devices that generate powerful high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge. Keep the wiring for the Temperature Controller's terminal block away from power cables carry high voltages or large currents. Also, do not wire power lines together with or parallel to Temperature Controller wiring. 8. Use the Temperature Controller within a power supply voltage and load that meet all specifications and ratings. 9. Set up the power supply so that the voltage will reach the rated voltage within 2 seconds after turning ON. 10. Allow at least 30 minutes for the Temperature Controller to warm up. 11. When using self-tuning, turn ON power for the load (e.g., heater) at the same time as or before supplying power to the Temperature Controller. 12. Install the appropriate switches and circuit breakers and label them accordingly so that power can be turned OFF in an emergency by the person operating the Temperature Controller. 13. If you remove the Controller from its case, do not touch or apply shock to the electronic parts inside. When placing the Controller back in the case, make sure that electronic parts do not come in contact with the case. 14. Use alcohol to clean the Temperature Controller. Do not use thinner or other solvent-based substances. 15. It will require 2 seconds for the outputs from the Temperature Controller to stabilize after turning ON the power supply. Design the system (e.g., the control panel) to allow for this time. 16. Outputs will turn OFF depending on the mode when switching to the initial setting mode. Confirm system safety before switching the mode. Digital Temperature Controllers E5CN/E5CN-U 21 Mounting Order the P2CF-11 or P3GA-11 Socket separately. Service Life 1. Use the Temperature Controller within the following temperature and humidity ranges: Temperature: -10 to 55°C (with no icing or condensation) Humidity: 25% to 85% If the Controller is installed inside a control board, the ambient temperature must be kept to under 55°C, including the temperature around the Controller. 2. The service life of electronic devices like Temperature Controllers is determined not only by the number of times the relay is switched but also by the service life of internal electronic components. Component service life is affected by the ambient temperature: the higher the temperature, the shorter the service life and, the lower the temperature, the longer the service life. Therefore, the service life can be extended by lowering the temperature of the Temperature Controller. 3. 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, use forced cooling by fans or other means of air ventilation to cool down the Temperature Controllers. When providing forced cooling, however, be careful not to cool down the terminals sections alone to avoid measurement errors. Measurement Accuracy 1. When extending or connecting the thermocouple lead wire, be sure to use compensating wires that match the thermocouple types. 2. When extending or connecting the lead wire of the platinum resistance thermometer, be sure to use wires that have low resistance and keep the resistance of the three lead wires the same. 3. Mount the Temperature Controller so that it is horizontally level. 4. If the measurement accuracy is low, check to see if 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 are not waterproof. Terminal Cover (order separately) Mounting Adapter (Accessory) E5CN-U Front-mounting Socket (Panel mounting is also possible.) Waterproof packing E5CN Panel Mounting to a Panel 1. To mount the Controller so that it is waterproof, insert the waterproof packing onto the Controller. Group mounting does not allow waterproofing. The waterproof packing is not required if waterproofing is not necessary. The Panel Mounting Adapter is also included with the E5CN-U. Waterproof packing is not included with the E5CN-U. 2. Insert the E5CN/E5CN-U into the mounting hole in the panel. 3. Push the adapter along the Controller body from the terminals up to the panel, and fasten it temporarily. 4. Tighten the two fixing screws on the adapter. Alternately tighten the two screws a little at time to keep them balanced. Tighten them to a torque of 0.29 to 0.39 N·m. Attaching the Terminal Cover Make sure that the “UP” letters on the E5CN are at the top and insert the terminal cover into the holes at the top and bottom of the Controller. Removing the Controller from the Case When carrying out maintenance on the Controller, the Controller can be removed from the case with the terminal leads still attached. The Controller can be removed from the case only with the E5CN. It cannot be removed with the E5CN-U.

Precautions for Correct Use ALM2 ALM3 HA PV OUT1 (3) OUT2 STOP CMW MANU SV 22 (2) (1) 2.0 1. It takes approximately two seconds for the outputs to turn ON from after the power supply is turned ON. Due consideration must be given to this time when incorporating Temperature Controllers in a sequence circuit. 2. When using self-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, self-tuning will not be performed properly and optimum control will not be achieved. 3. 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.) Avoid using the Controller in places near a radio, television set, or wireless installing. 4. These devices can cause radio disturbances which adversely affect the performance of the Controller. 0.4 Operating Precautions E5 C N 1. Insert the tool into the slots (one on the top and one on the bottom) and release the hooks. 2. Insert the tool into the gap between the front panel and rear case and pull out the front panel slightly. Hold both sides of the front panel and draw out the Controller towards you. Do not apply unnecessary force. 3. Before inserting the Controller, confirm that the sealing rubber is in place. Insert the Controller into the rear case until you hear a click. Press on the hooks on the top and bottom of the rear case to be sure that the hooks are securely locked in place.Be sure that electronic parts do not come in contact with the case. Digital Temperature Controllers E5CN/E5CN-U Wiring Precautions • Separate input leads and power lines to protect the Controller and its lines from external noise. • Use wires of a thickness of AWG24 (0.205 mm2) to AWG14 (2.081 mm2). The exposed current-carrying part to be inserted into terminals must be 5 to 6 mm. • We recommend using crimp terminals when wiring the terminals. • Tighten terminal screws to a torque of 0.74 to 0.90 N·m. • Use the following type of crimp terminals for M3.5 screws. 7.2 mm min. 7.2 mm min.
