Preface

The E5CN, E5CN-U, E5AN, E5EN, and E5GN are Digital Temperature Controllers. The E5CN and E5CN-U are both compact temperature controllers, with the E5CN featuring screw terminal connections, and the E5CN-U featuring socket pin connections. The E5GN can be connected using screw terminals or screwless clamp terminals. The main functions and characteristics of these Digital Temperature Controllers are as follows:

•Any of the following types of input can be used: thermocouple, platinum resistance thermometer, infrared sensor, analog voltage, or analog current.

•Either standard or heating/cooling control can be performed.

•Both auto-tuning and self-tuning are supported.

•Event inputs can be used to switch set points (multi-SP function), switch between RUN and STOP status, switch between automatic and manual operation, start/reset the simple program function, and perform other operations. (Event inputs are not applicable to the E5CN-U.)

•Heater burnout detection, heater short (HS) alarms, and heater overcurrent (OC) functions are supported. (Applicable to E5CN, E5AN, E5EN, and E5GN models with heater burnout detection function.)

•Communications are supported. (Applicable to E5CN, E5AN, E5EN, and E5GN models with communications.)

•User calibration of the sensor input is supported.

•The structure is waterproof (IP66). (Not applicable to the E5CN-U.)

•Conforms to UL, CSA, and IEC safety standards and EMC Directive.

•The PV display color can be switched to make process status easy to understand at a glance.

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.)

		tightening them.
		Make sure that there are no loose screws after tightening terminal
		screws to the specified torque of 0.74 to 0.90 N·m (see note).
		Be sure to confirm the polarity for each terminal before wiring the termi-
		nal block and connectors.
	Power supply inputs	Wire the power supply inputs correctly. Incorrect wiring will result in
		damage to the internal circuits.
Operating environ-	Ambient temperature	The ambient operating temperature for the product is −10 to 55°C (with
ment		no condensation or icing). To extend the service life of the product,
		install it in a location with an ambient temperature as low as possible. In
		locations exposed to high temperatures, if necessary, cool the products
		using a fan or other cooling method.

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.

1-1-3 Using the Keys

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

PF (Function (Auto/

Manual)) Key

(E5AN/EN 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.

O + M Keys

O + U Keys

O + D Keys

Press these keys to change to the protect level. For details on operations involving holding these keys down simultaneously, refer to 1-3 Setting Level Configuration and Key Operations.

To restrict set value changes (in order to prevent accidental or incorrect operations), these key operations require simultaneously pressing the O key along with U or D key. This applies only to the parameter for the password to move to protect level.

I/O Configuration and Main Functions Section 1-2

1-2-2 Main Functions

This section introduces the main E5CN/CN-U/AN/EN/GN 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 for temperature input

(i.e., E5_N-@@@@T):

Thermocouple:

K, J, T, E, L, U, N, R, S, B, W, PLII

Infrared temperature sensor:

ES1B

10 to 70°C, 60 to 120°C, 115 to 165°C,

140 to 260°C

Platinum resistance thermometer: Pt100, JPt100

Analog input:

0 to 50 mV

• Inputs with the following specifications can be connected for analog input

(i.e., E5_N-@@@@L):

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

Control Outputs

• A control output can be a relay, voltage (for driving SSR), or current out-

put, depending on the model.

• Long-life relay outputs (see note) use semiconductors for switching when

closing and opening the circuit, thereby reducing chattering and arcing

and improving durability. However, if high levels of noise or surge are

imposed between the output terminals, short-circuit faults may occasion-

ally occur. If the output becomes permanently shorted, there is the danger

of fire due to overheating of the heater. Design safety into the system,

including measures to prevent excessive temperature rise and spreading

of fire. Take countermeasures such as installing a surge absorber. As an

additional safety measure, provide error detection in the control loop.

(Use the Loop Burnout Alarm (LBA) and HS alarm that are provided for

the E5@N.)

• Always connect an AC load to a long-life relay output (see note). The out-

put will not turn OFF if a DC load is connected.

Note

Long-life relay outputs are not supported for the E5GN.

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.

10

	I/O Configuration and Main Functions		Section 1-2
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 or the E5AN/EN-@M@-500-N with

the E53-AKB for the E5AN/EN, the following functions can be executed using event inputs: switching set points (multi-SP, 4 points max.), switching RUN/STOP, switching between automatic and manual operation, starting/resetting the program, inverting direct/reverse operation, 100% AT execute/cancel, 40% AT execute/cancel, setting change 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, or the E5AN/EN-@@H@-500-N or E5AN/EN-@@HH@-500-N, the heater burnout detection function, HS alarm function, and heater overcurrent detection function can be used.

Communications

Functions

Note

External Power Supply for ES1B

Note

•Communications functions utilizing CompoWay/F (See note 1.), SYSWAY (See note 2.), or Modbus (See note 3.) can be used.

RS-485 Interface

Use the E53-CN@03N2 for the E5CN or the E53-EN03 for the E5AN/ EN.

RS-232C Interface

Use the E53-EN01 for the E5AN/EN.

(1)CompoWay/F is an integrated general-purpose serial communications protocol developed by OMRON. It uses commands compliant with the well-established FINS, together with a consistent frame format on OMRON Programmable Controllers to facilitate communications between personal computers and components.

(2)SYSWAY communications do not support alarm 3.

(3)Modbus is a communications control method conforming to the RTU Mode of Modbus Protocol. Modbus is a registered trademark of Schneider Electric.

(4)The E5CN and E5CN-U do not support the RS-232C interface.

The E5AN-@P@-N or E5EN-@P@-N with the E53-CN@P@N2 can be used as the power supply for ES1B Infrared Temperature Sensors.

The E5GN does not provide a power supply for an ES1B Infrared Temperature Sensor.

Transfer Output	A transfer output for 4 to 20 mA can be used with the E5AN/E5EN-@@F.
	For E5@N-C@@ models (models without “F” in the model number), the cur-
	rent output can be used as a simple transfer output.

Setting Level Configuration and Key Operations

Section 1-3

1-3 Setting Level Configuration and Key Operations

Parameters are divided into groups, each called a level. Each of the set values (setting items) in these levels is called a parameter. The parameters on the E5CN/CN-U/AN/EN/GN are divided into the following 9 levels.

When the power is turned ON, all of the display lights for approximately one second.

			these four levels is selected.
		(4) When the PF Setting is set to A-M in models with a PF Key (E5AN/EN)
		(5) When the PF Setting is set to PFDP in models with a PF Key (E5AN/EN)
Protect Level		• To switch to the protect level from the operation level, the adjustment
		level, or the monitor/setting item level, simultaneously hold down the O
		and M Keys for at least 3 seconds. (See note.) This level is for preventing
		unwanted or accidental modification of parameters. Protected levels will
		not be displayed, and so the parameters in that level cannot be modified.
		Note The key pressing time can be changed in Move to Protect Level pa-
			rameter (advanced function setting level).
Operation Level		• The operation level is displayed when the power is turned ON. You can
		move to the protect level, initial setting level, or adjustment level from this
		level.
		• Normally, select this level during operation. While operation is in progress,
		items such as the PV and manipulated variable (MV) can be monitored,
		and the set points, alarm values, and alarm upper and lower limits can be
		monitored and changed.
Adjustment Level		• To move to the adjustment level, press the O Key once (for less than 1 s).
		• This level is for entering set values and offset values for control. In addi-

tion to AT (auto-tuning), communications write enable/disable switching, hysteresis settings, multi-SP settings, and input offset parameters, it includes HB alarm, HS alarm, OC alarm, and PID constants. From the adjustment level, it is possible to move to the top parameter of the initial setting level, protect level, or operation level.

Monitor/Setting Item Level • To switch to the monitor/setting item level, press the PF Key from the operation level or adjustment level. The contents set for monitor/setting items 1 to 5 can be displayed. You can move from the monitor/setting item level to the operation level or initial setting level. (This level is supported by the E5AN and E5EN only.)

Manual Control Level • When the O Key is pressed for at least 3 seconds from the operation level's auto/manual switching display, the manual control level will be displayed. (The MANU indicator will light.)

•When the PF Setting is set to A-M (auto/manual) and the PF Key is pressed for more than one second from the operation level or adjustment level, the manual control level will be displayed (E5AN and E5EN only.)

•This is the level for changing the MV in manual mode.

•To return to the operation level, press the O Key for at least one second. It is also possible to return to the operation level by pressing the PF Key for more than one second when the PF Setting is set to A-M.

Level

•To move to the initial setting level from the operation level or the adjustment level, press the O Key for at least 3 seconds. The PV display flashes after one second. This level is for specifying the input type and selecting the control method, control period, setting direct/reverse operation, setting the alarm types, etc. You can move to the advanced function setting level or communications setting level from this level. To return to the operation level, press the O Key for at least one second. To move to the communications setting level, press the O Key for less than one second.

(When moving from the initial setting level to the operation level, all the indicators will light.)

Note Pressing the O Key for at least 3 seconds in the operation level's auto/manual switching display will move to the manual control level, and not the initial setting level.

•To move to the advanced function setting level, set the Initial Setting/Com-

munications Protect parameter in the protect level to 0 and then, in the initial setting level, input the password (−169).

•From the advanced function setting level, it is possible to move to the calibration level or to the initial setting level.

•This level is for setting the automatic display return time and standby sequence, and it is the level for moving to the user calibration and other functions.

•To move to the communications setting level from the initial setting level, press the O Key once (for less than 1 s). When using the communications function, set the communications conditions in this level. Communicating with a personal computer (host computer) allows set points to be read and written, and manipulated variables (MV) to be monitored.

1-3-1 Selecting Parameters

•Within each level, the parameter is changed in order (or in reverse order) each time the M Key is pressed. (In the calibration level, however, parameters cannot be changed in reverse order.)

1-3-2 Saving Settings

•If you press the M Key at the final parameter, the display returns to the top parameter for the current level.

•To change parameter settings, specify the setting using the U or D Key, and either leave the setting for at least two seconds or press the M Key. This saves the setting.

•When another level is selected after a setting has been changed, the contents of the parameter prior to the change is saved.

•When you turn the power OFF, you must first save the settings (by pressing the M Key). The settings are sometimes not changed by merely pressing the U or D Keys.

1-4 Communications Function

The E5CN/AN/EN/GN are provided with a communications function that enables parameters to be checked and set from a host computer. If the communications function is required, use the E53-CN@03N2 with the E5CN, or

the E53-EN03 or E53-EN01 with the E5AN/EN/GN. For details on the communications function, see the separate Communications Manual Basic Type.

Use the following procedure to move to the communications setting level.

1,2,3... 1. Press the O Key for at least three seconds to move from the operation level to the initial setting level.

2.Press the O Key for less than one second to move from the initial setting level to the communications setting level.

3.Select the parameters as shown below by pressing the M Key.

4.Press the U or D Key to change the parameter setting.
