Otherwise, minor injury from explosion may occasionallyoccur.Never disassemble, modify, or repair the product or touch any ofthe internal parts. Minor electric shock, fire, or malfunction mayoccasionally occur.CAUTION - Risk of Fire and Electric Shocka) This product is UL listed as Open Type Process Control Equipment. It must be mounted in an enclosure that does not allowfire to escape externally.b) More than one disconnect switch may be required to deenergize the equipment before servicing the product.c) Signal inputs are SELV, limited energy.*1d) Caution: To reduce the risk of fire or electric shock, do not interconnect the outputs of different Class 2circuits.*2If the output relays are used past their life expectancy, contactfusing or burning may occasionally occur.Always consider the application conditions and use the outputrelays within their rated load and electrical life expectancy.
The lifeexpectancy of output relays varies considerably with the outputload and switching conditions.*1*2A SELV circuit is one separated from the power supply with double insulation or reinforced insulation, thatdoes not exceed 30 V r.m.s. and 42.4 V peak or 60 VDC.A class 2 power supply is one tested and certified by UL as having the current and voltage of thesecondary output restricted to specific levels.ixCAUTIONTighten the terminal screws to between 1.13 and 1.36 N·m. Loosescrews may occasionally result in fire. (See note.)Set the parameters of the product so that they are suitable for thesystem being controlled. If they are not suitable, unexpectedoperation may occasionally result in property damage oraccidents.A malfunction in the Temperature Controller may occasionallymake control operations impossible or prevent alarm outputs,resulting in property damage.
To maintain safety in the event ofmalfunction of the Temperature Controller, take appropriate safetymeasures, such as installing a monitoring device on a separateline.A semiconductor is used in the output section of long-life relays. Ifexcessive noise or surge is impressed on the output terminals, ashort-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.Note The tightening torque for E5CN-U is 0.5 N·m.xPrecautions for Safe UseBe sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects onthe performance and functions of the product.
Not doing so may occasionally result in unexpected events.1) The product is designed for indoor use only. Do not use the product outdoors or in any of the followinglocations.• 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 Digital Temperature Controller within the rated ambient temperature and humidity.Gang-mounting two or more temperature controllers, or mounting temperature controllers above eachother may cause heat to build up inside the temperature controllers, which will shorten their service life.
Insuch a case, use forced cooling by fans or other means of air ventilation to cool down the DigitalTemperature Controllers.3) To allow heat to escape, do not block the area around the product. Do not block the ventilation holes onthe 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. For open-wiredconnection, use stranded or solid copper wires with a gage of AWG24 to AWG14 (equal to a crosssectional area of 0.205 to 2.081 mm2). (The stripping length is 5 to 6 mm.) Up to two wires or two crimpterminals can be inserted into a single terminal.6) Do not wire the terminals which are not used.7) To avoid inductive noise, keep the wiring for the Digital Temperature Controller's terminal block away frompower cables carry high voltages or large currents.
Also, do not wire power lines together with or parallelto Digital Temperature Controller wiring. Using shielded cables and using separate conduits or ducts isrecommended.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 noisefilter as close as possible to the temperature controller.Allow as much space as possible between the Digital Temperature Controller and devices that generatepowerful 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 orrelay contact.
If the voltage is applied gradually, the power may not be reset or output malfunctions mayoccur.10) Make sure that the Temperature Controller has 30 minutes or more to warm up after turning ON the powerbefore starting actual control operations to ensure the correct temperature display.11) When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or beforesupplying power to the Digital Temperature Controller.
If power is turned ON for the Digital TemperatureController before turning ON power for the load, self-tuning will not be performed properly and optimumcontrol will not be achieved.12) A switch or circuit breaker should be provided close to this unit. The switch or circuit breaker should bewithin 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 applyshock to the terminals or electronic components.
When inserting the interior of the product, do not allowthe electronic components to touch the case.xi14) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.15) Design system (control panel, etc) considering the 2 second of delay that the controller’s output to be setafter power ON.16) The output may turn OFF when shifting to certain levels. Take this into consideration when performingcontrol.17) The number of EEPROM write operations is limited. Therefore, use RAM write mode when frequentlyoverwriting data during communications or other operations.● Service LifeUse 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 under55°C, including the temperature around the Controller.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 theservice life and, the lower the temperature, the longer the service life. Therefore, the service life can beextended by lowering the temperature of the Temperature Controller.When two or more Temperature Controllers are mounted horizontally close to each other or verticallynext to one another, the internal temperature will increase due to heat radiated by the TemperatureControllers and the service life will decrease. In such a case, use forced cooling by fans or othermeans 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.● Ambient NoiseTo avoid inductive noise, keep the wiring for the Digital Temperature Controller's terminal block wiringaway from power cables carrying high voltages or large currents.
Also, do not wire power lines togetherwith or parallel to Digital Temperature Controller 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 thenoise filter as close as possible to the Temperature Controller.Allow as much space as possible between the Digital Temperature Controller and devices that generate powerful high frequencies (high-frequency welders, high-frequency sewing machines, etc.) orsurge.● Ensuring Measurement AccuracyWhen extending or connecting the thermocouple lead wire, be sure to use compensating wires thatmatch the thermocouple types.When extending or connecting the lead wire of the platinum resistance thermometer, be sure to usewires that have low resistance and keep the resistance of the three lead wires the same.Mount the Temperature Controller so that it is horizontally level.If the measurement accuracy is low, check to see if input shift has been set correctly.● WaterproofingThe degree of protection is as shown below.
