Doing so mayoccasionally result in electric shock, fire, or malfunction.Do not use the product where subject to flammable or explosivegas. 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 ControlEquipment. It must be mounted in an enclosure that does notallow fire to escape externally.b) When using more than one shutoff switch, always turn OFF allthe shutoff switches to ensure that no power is being suppliedbefore servicing the product.c) Signal inputs are SELV, limited energy.*1d) Caution: To reduce the risk of fire or electric shock, do notinterconnect the outputs of different Class 2 circuits.*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 An SELV circuit is one separated from the power supply with double insulation orreinforced insulation, that does not exceed 30 V r.m.s. and 42.4 V peak or60 VDC.*2 A class 2 power supply is one tested and certified by UL as have the current andvoltage of the secondary output restricted to specific levels.VCAUTIONTighten the terminal screws to between 1.13 and 1.36 N·m. Loosescrews may occasionally result in fire.*3Set 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 excessivetemperature increase and to prevent fire from spreading.*3 The tightening torque for E5CN-U is 0.5 N·m.VIPrecautions for Safe UseBe sure to observe the following precautions to prevent operation failure, malfunction, or adverse affectson the performance and functions of the product. Not doing so may occasionally result in unexpectedevents.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 servicelife.
In such a case, use forced cooling by fans or other means of air ventilation to cool down theDigital Temperature Controllers.3) To allow heat to escape, do not block the area around the product. Do not block the ventilation holeson the product.4) Be sure to wire properly with correct polarity of terminals.5) Use specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. To connect bare wires,use stranded or solid copper wires with a gage of AWG24 to AWG14 (equal to cross-sectional areasof 0.205 to 2.081 mm2).
(The stripping length is 5 to 6 mm.) Up to two wires or two crimp terminalscan 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 awayfrom power cables carry high voltages or large currents. Also, do not wire power lines together with orparallel to Digital Temperature Controller wiring.
Using shielded cables and using separate conduits orducts 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 inductancecomponent).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 thatgenerate 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 aswitch or relay contact.
If the voltage is applied gradually, the power may not be reset or outputmalfunctions may occur.10) Make sure that the Temperature Controller has 30 minutes or more to warm up after turning ON thepower before starting actual control operations to ensure the correct temperature display.VII11) When using 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 Temperature Controller before turning ON power for the load, self-tuning will not be performed properly andoptimum control will not be achieved.12) A switch or circuit breaker should be provided close to this unit. The switch or circuit breaker shouldbe 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 norapply shock to the terminals or electronic components.
When inserting the interior of the product, donot 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 system (control panel, etc) considering the 2 second of delay that the controller’s output to beset after 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.VIIIConventions Used in This Manual■ How This Manual is OrganizedOverviewDescriptions in this manual are separated by the communications method.Read the sections that are application to the system being used.OverviewCompoWay/FCom DataCommunications DataCompoWay/F•SYSWAYSYSWAYSYSWAYModbusAppendix■ Related ManualsThis manual describes the communications functions of the E5CN/AN/EN.
