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)When using more than one shutoff switch, always turn OFF all the shutoff switches to ensure that no power is being supplied before servicing the product.

c)Signal inputs are SELV, limited energy. (See note 1.)

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

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.

Note 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.

CAUTION

Tighten the terminal screws to between 0.74 and 0.90 N·m. 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 Digital 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 Digital Controller, take appropriate safety measures, such as installing a monitoring device on a separate line.

When inserting the body of the Digital Controller into the case, confirm that the hooks on the top and bottom are securely engaged with the case. If the body of the Digital 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.

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.

1)The product is designed for indoor use only. Do not use the product outdoors or 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 Controller within the rated ambient temperature and humidity.

Gang-mounting two or more Digital Controllers, or mounting Digital Controllers above each other may cause heat to build up inside the Digital 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 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 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 areas of 0.205 to 2.081 mm2). (The stripping length is 5 to 6 mm.) Up to two wires of same size and type, or two crimp terminals 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 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 Controller wiring. Using shielded cables and using separate conduits or ducts is recommended.

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 Digital controller.

Allow as much space as possible between the Digital 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.

10)Make sure that the Digital 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 using self-tuning, turn ON power for the load (e.g., heater) at the same time as or before supplying power to the Digital Controller. If power is turned ON for the Digital 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 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 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 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 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 Digital Controller, check the condition of the terminals. If corroded terminals are used, contact failure in the terminals may cause the temperature inside the Digital Controller to increase, possibly resulting in fire. If the terminals are corroded, replace the case as well.

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

23)Check the specifications of the Control Output Unit and assemble it correctly.

24)When mounting the Control Output Unit, read and follow all relevant information in the product catalogs and manuals.

25)When applying Lloyd's standards, install the Digital Controller according to the requirements given in

Shipping Standards.

● Service Life

Use the Digital 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 Digital 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 Digital Controller.

When two or more Digital 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 Digital 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 Digital 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 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 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 Digital Controller.

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

xii

● 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 Digital 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

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 Digital Controllers into a control panel or similar device.

2)Make sure that the Digital 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 Digital Controller. If power is turned ON for the Digital 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 Digital 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 Digital 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 E5@N-H Digital Controllers 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 E5@N-H Digital Controllers comply with installation categories ENV1 and ENV2 of Lloyd's standards. 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

1-1-3 Using the Keys

This section describes the basic functions of the front panel keys.

PF (Function (Auto/

Manual)) Key

(E5AN/EN-H Only)

This is a function key. When it is pressed for at least 1 second, the function set in the PF Setting parameter will operate.

Example: When A-M (auto/manual) is selected in the PF Setting parameter (initial value: A-M), the key operates as an auto/manual switch, switching between Auto Mode and Manual Mode. If the key is pressed for more than 1 second (regardless of key release timing), the mode will switch.

O Key	Press this key to move between setting levels. The setting level is selected in
	the following order: operation level: adjustment level, initial setting level, com-
	munications setting level.
M Key	Press this key to change parameters within a setting level.
	The parameters can be reversed by holding down the key (moving one per
	second in reverse order).
U Key	Each press of this key increments the value displayed on the No. 2 display or
	advances the setting. Holding the key down speeds up the incrementation.
D Key	Each press of this key decrements values displayed on the No. 2 display or
	reverses the setting. Holding the key down speeds up the incrementation.

1-2-2 Main Functions

This section introduces the main E5@N-H functions. For details on particular functions and how to use them, refer to SECTION 3 Basic Operation and following sections.

Input Sensor Types	• The following input sensors can be connected.:
	Thermocouple:	K, J, T, E, L, U, N, R, S, B, W, PLII
	Platinum resistance thermometer: Pt100, JPt100
	Current input:	4 to 20 mA DC, 0 to 20 mA DC
	Voltage input:	1 to 5 VDC, 0 to 5 V DC, 0 to 10 V DC

	I/O Configuration and Main Functions		Section 1-2
Control Outputs		• A control output can be a relay output, voltage output (for driving SSR),
		linear voltage output, SSR output, or current output, depending on the
		model.
		• With the E5CN-H@2@@, auxiliary output 2 is used as control output (cool-
		ing) when heating/cooling control is selected. (It is also possible to allo-
		cate a different output.) Therefore, use auxiliary output 1 if an auxiliary
		output is required while using heating/cooling control.
Alarms		• Set the alarm type and alarm value or the alarm value upper and lower
		limits.
		• If necessary, a more comprehensive alarm function can be achieved by
		setting a standby sequence, alarm hysteresis, auxiliary output close in
		alarm/open in alarm, alarm latch, alarm ON delay, and alarm OFF delay.
		• If the Input Error Output parameter is set to ON, the output assigned to
		alarm 1 function will turn ON when an input error occurs.
		• If the Remote SP Input Error Output parameter is set to ON, the output
		assigned to the alarm 1 function will turn ON when an input error occurs.
Control Adjustment		• Optimum PID constants can be set easily by performing AT (auto-tuning)
		or ST (self-tuning).
Event Inputs		• With the E53-CN@B@N2 for the E5CN-H (for two event inputs), the
		E5AN/EN-H@B@M@-500 for E5AN/EN-H (for two event inputs) or the
		E5AN/EN-H@B@M@-500 with the E53-AKB for the E5AN/EN-H (for four
		event inputs), the following functions can be executed using event inputs:

switching banks, switching RUN/STOP, switching between automatic and manual operation, starting/resetting the program, inverting direct/reverse operation, switching SP modes, 100% AT execute/cancel, 40% AT execute/cancel, setting change enable/disable, communications writing enable/disable and canceling the alarm latch.

Heater Burnout, HS Alarm,

and Heater Overcurrent

•With the E53-CN@H@N2 or E53-CN@HH@N2 for the E5CN-H, or the E5AN/EN-H@@H@-500 or E5AN/EN-H@@HH@-500, the heater burnout detection function, HS alarm function, and heater overcurrent detection function can be used.

Communications
