■ 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.

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 deenergize 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.

*1 A 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.

x

CAUTION

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

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 Temperature Controller may occasionally make control operations impossible or prevent alarm outputs, resulting in property damage. To maintain safety in the event of malfunction of the Temperature Controller, 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.

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.

*3 The tightening torque is 0.5 N·m for the E5CN-U and 0.43 to 0.58 N·m for the E5GN. The terminal torque is 0.5 to 0.6 N·m for auxiliary output 2 on the E5GN.

Precautions for Safe Use

Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects on the performance and functions of the product. Not doing so may occasionally result in unexpected events. Use the product within the specifications.

1)The product is designed for indoor use only. Do not use the product outdoors or in any of the following locations. Do not use or store the product in any of the following locations.

•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 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 Digital 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 of crimp terminals for the E5CN, E5AN, or E5EN (M3.5, width of 7.2 mm or less). For open-wired connections to the E5CN, E5AN, or E5EN, use stranded or solid copper wires with a gauge of AWG24 to AWG14 (equal to a cross-sectional area of 0.205 to 2.081 mm2). (The stripping length is 5 to 6 mm.) Up to two wires of the same size and type or two crimp terminals can be connected to one terminal. Do not connect more than two wires or more than two crimp terminals to the same terminal.

Use the specified size of crimp terminals for the E5GN (M3.0, width of 5.8 mm or less). For open-wired connections to the E5GN, use stranded or solid copper wires with a gauge of AWG24 to AWG18 (equal to a cross-sectional area of 0.205 to 0.8231 mm2). (The stripping length for screw terminals is 6 to 8 mm. The stripping length for screwless clamp terminals is 10 mm. The stripping length for auxiliary output 2 is 6 mm.) Up to two wires of the same size and type or two crimp terminals can be connected to one terminal. Do not connect more than two wires or more than two crimp terminals to the same terminal.

Ferrules for screwless clamp terminals must be 0.8 to 1.4 mm in diameter and the exposed conductor must be 8 to 12 mm in length. Ferrules for auxiliary output 2 must be 0.8 to 1.4 mm in diameter and the exposed conductor must be 6 mm in length.

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 from power cables carry high voltages or large currents. Also, do not wire power lines together with 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 the noise 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.) 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.

xii

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.

11)When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or before supplying 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 and optimum control will not be achieved.

12)A switch or circuit breaker should be provided close to this unit. The switch or circuit breaker should 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 removing the body of the E5CN, E5AN, or E5EN from the case, 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.

Always turn OFF the power supply before removing the terminal block from the E5GN, and never touch nor apply shock to the terminals or electronic components.

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 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 Digital Temperature Controller to discharge static electricity from your body.

19)Do not remove the terminal block from the E5CN, E5AN, or E5EN. Doing so may result in failure or malfunction.

20)Control outputs 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 E5CN, E5AN, or E5EN, check the condition of the terminals. If corroded terminals are used, contact failure in the terminals may cause the temperature inside the E5CN, E5AN, or E5EN to increase, possibly resulting in fire. If the terminals are corroded, replace the case as well.

When removing the terminal block of the E5GN to replace the Digital Temperature Controller, check the condition of the terminals. If corroded terminals are used, contact failure in the terminals may cause the temperature inside the Digital Temperature Controller to increase, possibly resulting in fire. If the terminals are corroded, replace the terminal block as well.

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

23)When applying Lloyd's standards, install the Digital Temperature Controller according to the requirements given in Shipping Standards.

24)Do not use the Temperature Controller if the front sheet is peeling off or torn.

● Service Life

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.

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.

xiii

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.

● Ambient Noise

To avoid inductive noise, keep the wiring for the Digital Temperature Controller's terminal block wiring away from power cables carrying high voltages or large currents. Also, do not wire power lines together with 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 the noise 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.) or surge.

● Ensuring 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 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.

● 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)

xiv

Precautions for Operation

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 into a control panel or similar device.

2)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.

3)When executing 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. 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. The Controller may cause radio disturbance for these devices.

Shipping Standards

The E5CN, E5CN-H, E5AN, E5AN-H, E5EN, and E5EN-H comply with Lloyd's standards. When applying the standards, the following installation and wiring requirements must be met in the application.

■ Application Conditions

1) Installation Location

The E5CN, E5CN-H, E5AN, E5AN-H, E5EN, and E5EN-H comply with installation category ENV1 and ENV2 of Lloyd's standards. Therefore, they must be installed in a location equipped with air conditioning. They must therefore be installed in a location equipped with air conditioning. They cannot be used on the bridge or decks, or in a location subject to strong vibration.

2) Wiring Conditions

Install the recommended ferrite core and wrap the line around it three turns for the applicable lines (e.g., power supply cable line and signal lines) of the models listed in the following table. (See illustrations.) Install the ferrite cores as close to the terminal block of the E5@N as possible. (As a guideline, the ferrite core should be within 10 cm of the terminal block.)

■ Upgraded Functions

The functionality of the E5CN, E5CN-U, E5AN, and E5EN was improved starting from December 2007 production.

The functionality of the E5GN was improved starting from August 2009 production.

The design of the front panel can be used to differentiate between the previous and upgraded models.

● E5CN/CN-U

The upgraded Controllers are basically compatible with the previous Controllers. Terminal arrangements, terminal sizes, and panel mounting depth have not been changed.

● E5AN/EN

Although the upgraded Controllers are compatible with the previous Controllers, terminal arrangements have been changed. Terminal sizes and panel mounting depth have not been changed.

● E5GN

Model numbers have changed accompanying the introduction of universal input capability. The default setting of the input type parameter of the E5GN-@@@P (models with resistance thermometers) has been changed from a Pt100 resistance thermometer to a K thermocouple. Make sure the setting of the input type parameter agrees with the temperature sensor that is being used.

The terminal block has also been changed, which means the wiring methods and terminal arrangement are different.

Other changes outlined in the following tables. Refer to relevant pages in the manual for details.

Conventions Used in This Manual

Model Notation

The E5CN-@@@, E5CN-@@@U, E5AN-@@@, E5EN-@@@, and E5GN-@@@ are given as the E5CN, E5CN-U, E5AN, E5EN, and E5GN when they share functionality.

The following notation is used when specifying differences in functionality.

Notation	Options
E5@N-@@@B	Two event inputs
E5@N-@@@03	RS-485 communications
E5@N-@@H	One of HB, HS, and heater overcurrent detection
E5@N-@@HH	Two of HB, HS, and heater overcurrent detection (See note 1.)
E5@N-@Q	Control output 2 (voltage output) (See note 1.)
E5@N-@@P	External power supply to ES1B (See note 1.)
E5@N-@@@01	RS-232C communications (See note 2.)
E5@N-@@F	Transfer output (See note 3.)

Note: (1) Excluding the E5GN.

(2)Excluding the E5CN.

(3)The E5AN and E5EN only.

Meanings of Abbreviations

The following abbreviations are used in parameter names, figures and in text explanations. These abbreviations mean the following:

Symbol	Term
PV	Process value
SP	Set point
SV	Set value
AT	Auto-tuning
ST	Self-tuning
HB	Heater burnout
HS	Heater short (See note 1.)
OC	Heater overcurrent
LBA	Loop burnout alarm
EU	Engineering unit (See note 2.)

Note: (1) A heater short indicates that the heater remains ON even when the control output from the Temperature Controller is OFF because the SSR has failed or for any other reason.

(2)“EU” stands for Engineering Unit. EU is used as the minimum unit for engineering units such as °C,

m, and g. The size of EU varies according to the input type.

For example, when the input temperature setting range is –200 to +1300°C, 1 EU is 1°C, and when the input temperature setting range is –20.0 to +500.0°C, 1 EU is 0.1°C.

For analog inputs, the size of EU varies according to the decimal point position of the scaling setting, and 1 EU becomes the minimum scaling unit.
