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.)

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 A ut o - tu n i ng

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 Tempera-

ture 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.

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 occasion­ally 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 out­put 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.

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.

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.

12

Note (1) You can return to the operation level by executing a software reset.

(2) You cannot move to other levels by operating the keys on the front panel

from the calibration level. You must turn OFF the power supply.

(3) From the manual control level, key operations can be used to move to the

operation level only.

Of these levels, the initial setting level, communications setting level,
advanced function setting level, and calibration level can be used only
when control is stopped. Control outputs are stopped when any of
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 addi­tion 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.

13

Setting Level Configuration and Key Operations Section 1-3

Initial Setting Level • To move to the initial setting level from the operation level or the adjust-

ment 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.

Advanced Function
Setting Level

Communications Setting
Level

• To move to the advanced function setting level, set the Initial Setting/Com­munications 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.)

Parameter 4

• 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 com-

munications 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 lev-

el 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.
