## **Alarm Outputs** 

Each alarm can be independently set to one of the following 13 alarm types. The default is _2: Upper limit_ . Auxiliary outputs are allocated for alarms. ON delays and OFF delays (0 to 999 s) can also be specified. 

**Note:** For models with heater burnout, SSR failure, and heater overcurrent detection, alarm 1 will be an OR output of the alarm selected from the following alarm types and the alarms for heater burnout, SSR failure, and heater overcurrent. To output only a heater burnout alarm, SSR failure alarm, and heater overcurrent alarm for alarm 1, set the alarm type to 0 (i.e., no alarm function). 

- ✽1. With set values 1, 4 and 5, the upper and lower limit values can be set independently for each alarm type, and are expressed as “L” and “H.”

## **External Connections** 

- A voltage output (control output, for driving SSR) is not electrically insulated from the internal circuits. When using a grounding thermocouple, do not connect any of the control output terminals to ground. (If the control output terminals are connected to ground, errors will occur in the measured temperature values as a result of leakage current.) 

- Consult with your OMRON representative before using the external power supply for the ES1B for any other purpose.

## **Waterproof Packing** 

## **Y92S-29 (for DIN 48** × **48)** 

**==> picture [35 x 58] intentionally omitted <==**

Order the Waterproof Packing separately if it becomes lost or damaged. 

The Waterproof Packing can be used to achieve an IP66 degree of protection. 

(Deterioration, shrinking, or hardening of the waterproof packing may occur depending on the operating environment. Therefore, periodic replacement is recommended to ensure the level of waterproofing specified in IP66. The time for periodic replacement depends on the operating environment. Be sure to confirm this point at your site. Consider one year a rough standard. OMRON shall not be liable for the level of water resistance if the customer does not perform periodic replacement.) 

The Waterproof Packing does not need to be attached if a waterproof structure is not required.

## **Safety Precautions** 

## ! **CAUTION** 

Do not touch the terminals while power is being supplied. Doing so may occasionally result in minor injury due to electric shock. 

Do not allow pieces of metal, wire clippings, or fine metallic shavings or filings from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction. 

Do not use the product where subject to flammable or explosive gas. Otherwise, minor injury from explosion may occasionally occur. 

Do not leave the cable for the Support Software connected to the product. Malfunction may occur due to noise in the cable. 

Do not use the Temperature Controller or Conversion Cable if it is damaged. Doing so may occasionally result in minor electric shock or fire. 

Never disassemble, modify, or repair the product or touch any of the internal parts. Minor electric shock, fire, or malfunction may occasionally occur. 

CAUTION - Risk of Fire and Electric Shock 

- a) This product is UL listed as Open Type Process Control Equipment. It must be mounted in an enclosure that does not allow fire to escape externally. 

- b) More than one disconnect switch may be required to de-energize the equipment before servicing the product. 

- c) Signal inputs are SELV, limited energy. ✽1 

- d) Caution: To reduce the risk of fire or electric shock, do not interconnect the outputs of different Class 2 circuits. ✽2 

If the output relays are used past their life expectancy, contact fusing or burning may occasionally occur. Always consider the application conditions and use the output relays within their rated load and electrical life expectancy. The life expectancy of output relays varies considerably with the output load and switching conditions. 

Tighten the terminal screws to between 0.74 and 0.90 N·m. ✽3 Loose screws may occasionally result in fire. 

Set the parameters of the product so that they are suitable for the system being controlled. If they are not suitable, unexpected operation may occasionally result in property damage or accidents. 

A malfunction in the product may occasionally make control operations impossible or prevent alarm outputs, resulting in property damage. To maintain safety in the event of malfunction of the product, take appropriate safety measures, such as installing a monitoring device on a separate line. 

A semiconductor is used in the output section of long-life relays. If excessive noise or surge is impressed on the output terminals, a short-circuit failure is likely to occur. If the output remains shorted, fire will occur due to overheating of the heater or other cause. Take measures in the overall system to prevent excessive temperature increase and to prevent fire from spreading. 

Do not allow pieces of metal or wire cuttings to get inside the cable connector for the Support Software.  Failure to do so may occasionally result in minor electric shock, fire, or damage to equipment. 

Do not allow dust and dirt to collect between the pins in the connector on the Conversion Cable. Failure to do so may occasionally result in fire. 

**==> picture [34 x 208] intentionally omitted <==**

When inserting the body of the Temperature Controller into the case, confirm that the hooks on the top and bottom are securely engaged with the case. If the body of the Temperature Controller is not inserted properly, faulty contact in the terminal section or reduced water resistance may occasionally result in fire or malfunction. 

When connecting the Control Output Unit to the socket, press it in until there is no gap between the Control Output Unit and the socket. Otherwise contact faults in the connector pins may occasionally result in fire or malfunction. 

- ✽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 having the current and voltage of the secondary output restricted to specific levels. 

- ✽3. The tightening torque for E5CN-U is 0.5 N·m. 

## **Precautions for Safe Use** 

Be sure to observe the following precautions to prevent malfunction or adverse affects on the performance or functionality of the product. Not doing so may occasionally result in faulty operation. 

**1.** This product is specifically designed for indoor use only. Do not use this product in the following places: 

- Places directly subject to heat radiated from heating equipment. 

- Places subject to splashing liquid or oil atmosphere. 

- Places subject to direct sunlight. 

- Places subject to dust or corrosive gas (in particular, sulfide gas and ammonia gas). 

- Places subject to intense temperature change. 

- Places subject to icing and condensation. 

- Places subject to vibration and large shocks. 

**2.** Use and store the product within the rated ambient temperature and humidity. 

- Gang-mounting two or more Temperature Controllers, or mounting Temperature Controllers above each other may cause heat to build up inside the Temperature Controllers, which will shorten their service life. In such a case, use forced cooling by fans or other means of air ventilation to cool down the Temperature Controllers. 

**3.** To allow heat to escape, do not block the area around the product. Do not block the ventilation holes on the product. 

**4.** Be sure to wire properly with correct polarity of terminals. 

**5.** Use the specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. To connect bare wires to the terminal block, use stranded or solid copper wires with a gage of AWG24 to AWG14 (equal to a cross-sectional area of 0.205 to 2.081 mm[2] ). (The stripping length is 5 to 6 mm.) Up to two wires of the same size and type or two crimp terminals can be inserted into a single terminal. 

**6.** Do not wire the terminals that are not used. 

**7.** To avoid inductive noise, keep the wiring for the product’s terminal block away from power cables carry high voltages or large currents. Also, do not wire power lines together with or parallel to product wiring. Using shielded cables and using separate conduits or ducts is recommended. 

- Attach a surge suppressor or noise filter to peripheral devices that generate noise (in particular, motors, transformers, solenoids, magnetic coils, or other equipment that have an inductance component). 

When a noise filter is used at the power supply, first check the voltage or current, and attach the noise filter as close as possible to the product. 

Allow as much space as possible between the product and devices that generate powerful high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge. 

**8.** Use this product within the rated load and power supply. 

**9.** Make sure that the rated voltage is attained within two seconds of turning ON the power using a switch or relay contact. If the voltage is applied gradually, the power may not be reset or output malfunctions may occur. 

**10.** Make sure that the Temperature Controller has 30 minutes or more to warm up after turning ON the power before starting actual control operations to ensure the correct temperature display. 

Basic-type Digital Temperature Controller **E5CN/E5CN-U** 

18 

**11.** When executing self-tuning, turn ON power to the load (e.g., heater) at the same time as or before supplying power to the product. If power is turned ON to the product before turning ON power to the load, self-tuning will not be performed properly and optimum control will not be achieved. 

**12.** A switch or circuit breaker must be provided close to the product. The switch or circuit breaker must be within easy reach of the operator, and must be marked as a disconnecting means for this unit. 

**13.** Always turn OFF the power supply before pulling out the interior of the product, and never touch nor apply shock to the terminals or electronic components. When inserting the interior of the product, do not allow the electronic components to touch the case. 

**14.** Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol. 

**15.** Design the system (e.g., control panel) considering the 2 seconds of delay that the product's output to be set after power ON. 

**16.** The output may turn OFF when shifting to certain levels. Take this into consideration when performing control. 

**17.** The number of EEPROM write operations is limited. Therefore, use RAM write mode when frequently overwriting data during communications or other operations. 

**18.** Always touch a grounded piece of metal before touching the Temperature Controller to discharge static electricity from your body. 

**19.** Do not remove the terminal block. Doing so may result in failure or malfunction. 

**20.** Control outputs (for driving SSR) that are voltage outputs are not isolated from the internal circuits. When using a grounded thermocouple, do not connect any of the control output terminals to ground. (Doing so may result in an unwanted circuit path, causing error in the measured temperature.) 

**21.** When replacing the body of the Temperature Controller, check the condition of the terminals. If corroded terminals are used, contact failure in the terminals may cause the temperature inside the Temperature Controller to increase, possibly resulting in fire. If the terminals are corroded, replace the case as well. 

**22.** Use suitable tools when taking the Temperature Controller apart for disposal. Sharp parts inside the Temperature Controller may cause injury. 

**23.** Before connecting an Output Unit, confirm the specifications and thoroughly read relevant information in the datasheet and manual for the Temperature Controller. 

**24.** Check the orientation of the connectors on the Conversion Cable before connecting the Conversion Cable. Do not force a connector if it does not connect smoothly. Using excessive force may damage the connector. 

**25.** Do not place heavy object on the Conversion Cable, bend the cable past its natural bending radius, or pull on the cable with undue force. 

**26.** Do not connect or disconnect the Conversion Cable while communications are in progress. Product faults or malfunction may occur. 

**27.** Make sure that the Conversion Cable's metal components are not touching the external power terminals. 

**28.** Do not touch the connectors on the Conversion Cable with wet hands. Electrical shock may result. 

**29.** Before using infrared communications, correctly attach the enclosed Mounting Adapter to the cable for the Support Software. When connecting the infrared port on the cable to the Support Software into the Adapter, insert the connector to the specified line. Communications may not be possible if the connector is not connected properly. 

## **Precautions for Correct Use** 

## **Service Life** 

**1.** Use the product within the following temperature and humidity ranges: Temperature: −10 to 55° C (with no icing or condensation) Humidity: 25% to 85% 

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 product 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. 

- Front panel: IP66 

- Rear case: IP20, Terminal section: IP00 

- (E5CN-U: Front panel: IP50, rear case: IP20, terminals: IP00) 

## **Operating Precautions** 

**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.) 

**4.** Avoid using the Controller in places near a radio, television set, or wireless installing. These devices can cause radio disturbances which adversely affect the performance of the Controller. 

## **Others** 

   **1.** The disk that is included with the Conversion Cable is designed for a computer CD-ROM driver. Never attempt to play the disk in a general-purpose audio player. 

   **2.** Do not connect or disconnect the Conversion Cable connector repeatedly over a short period of time. The computer may malfunction. 

   **3.** After connecting the Conversion Cable to the computer, check the COM port number before starting communications. The computer requires time to recognize the cable connection. This delay does not indicate failure. 

   **4.** Do not connect the Conversion Cable through a USB hub. Doing so may damage the Conversion Cable. 

   **5.** Do not use an extension cable to extend the Conversion Cable length when connecting to the computer. Doing so may damage the Conversion Cable. 

- If the product is installed inside a control board, the ambient temperature must be kept to under 55° C, including the temperature around the product. 

**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

## **Precautions when Wiring** 

- Separate input leads and power lines in order to prevent external noise. 

- Use wires with a gage of AWG24 (cross-sectional area: 0.205 mm[2] ) to AWG14 (cross-sectional area: 2.081 mm[2] ) twistedpair cable (stripping length: 5 to 6 mm). 

- Use crimp terminals when wiring the terminals. 

- Tighten the terminal screws to a torque of 0.74 to 0.90 N·m, however the terminal screws on the E5CN-U must be tightened to a torque of 0.5 N·m. 

- Use the following types of crimp terminals for M3.5 screws.

   - Do not remove the terminal block. Doing so will result in malfunction or failure. 

**1.** The Panel Mounting Adapter is also included with the E5CN-U. There is no waterproof packing included with the E5CN-U. 

**2.** Insert the E5CN/E5CN-U into the mounting hole in the panel. 

**3.** Push the adapter from the terminals up to the panel, and temporarily fasten the E5CN/E5CN-U. 

**4.** Tighten the two fastening screws on the adapter. Alternately tighten the two screws little by little to maintain a balance. Tighten the screws to a torque of 0.29 to 0.39 N·m. 

## **Mounting the Terminal Cover** 

Make sure that the “UP” mark is facing up, and then attach the E53COV17 Terminal Cover to the holes on the top and bottom of the Temperature Controller. 

## **Removing the Temperature Controller from the Case** 

The Temperature Controller can be removed from the case to perform maintenance without removing the terminal leads. This is possible for only the E5CN, E5AN, and E5EN, and not for the E5CN-U. Check the specifications of the case and Temperature Controller before removing the Temperature Controller from the case.

**1.** Insert a flat-blade screwdriver into the two tool insertion holes (one on the top and one on the bottom) to release the hooks. 

**2.** Insert the flat-blade screwdriver in the gap between the front panel and rear case, and pull out the front panel slightly. Hold the top and bottom of the front panel and carefully pull it out toward you, without applying unnecessary force. 

**3.** When inserting the body of the Temperature Controller into the case, make sure the PCBs are parallel to each other, make sure that the sealing rubber is in place, and press the E5CN toward the rear case into position. While pushing the E5CN into place, push down on the hooks on the top and bottom surfaces of the rear case so that the hooks are securely locked in place. Be sure that electronic components do not come into contact with the case.
