Meanings of Abbreviations
The following abbreviations are used in parameter names, figures and in text explanations. These
abbreviations mean the following:
Note “EU” stands for Engineering Unit. EU is used as the minimum unit for engi-
neering 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.
In the case of analog input, the size of EU varies according to the decimal
point position of the scaling setting, and 1 EU becomes the minimum scaling
unit.

xiv
Safety Precautions 3
3. To reduce induction noise, separate the high-voltage or large-current pow-
er lines from other lines, and avoid parallel or common wiring with the pow-
er lines when you are wiring to the terminals. We recommend using
separating pipes, ducts, or shielded lines.
4. Do not use this product in the following places:
• Places subject to dust or corrosive gases (in particular, sulfide gas and
ammonia gas)
• Places subject to high humidity, condensation or freezing
• Places subject to direct sunlight
• Places subject to vibration and large shocks
• Places subject to splashing liquid or oily atmosphere
• Places directly subject to heat radiated from heating equipment
• Places subject to intense temperature changes
5. To allow heat to escape, do not block the area around the product. (Ensure
that enough space is left for the heat to escape.)
• Do not block the ventilation holes on the casing.
6. When you draw out the internal mechanism from the housing, never touch
electric components inside or subject the internal mechanism to shock.
7. Cleaning: Do not use paint thinner or the equivalent. Use standard grade
alcohol to clean the product.
8. Use specified size (M3.5, width 7.2 mm or less) crimped terminals for wir-
ing.
9. Allow as much space as possible between the E5CN and devices that gen-
erate powerful high-frequency noise (e.g. high-frequency welders, high-
frequency sewing machines) or surges.
10. When executing self-tuning, turn the load (e.g. heater) ON simultaneously
or before you turn the E5CN ON. If you turn the E5CN ON before turning
the load ON, correct self-tuning results and optimum control may no longer
be obtained.
11. Use a 100 to 240 VAC (50/60 Hz), 24 VAC (50/60 Hz) or 24 VDC power
supply matched to the power specifications of the E5CN. Also, make sure
that rated voltage is attained within two seconds of turning the power ON.
12. Attach a surge suppresser or noise filter to peripheral devices that gener-
ate noise (in particular, motors, transformers, solenoids, magnetic coils or
other equipment that have an inductance component).
13. When mounting a noise filter on the power supply, be sure to first check the
filter’s voltage and current capacity, and then mount the filter as close as
possible to the E5CN.
14. Use within the following temperature and humidity ranges:
• Temperature: -10 to 55°C, Humidity: 25 to 85% (with no icing or conden-
sation)
If the E5CN is installed inside a control board, the ambient temperature
must be kept to under 55°C, including the temperature around the E5CN.
If the E5CN is subjected to heat radiation, use a fan to cool the surface of
the E5CN to under 55°C.
15. Store within the following temperature and humidity ranges:
• Temperature: -25 to 65°C, Humidity: 25 to 85% (with no icing or conden-
sation)
16. Never place heavy objects on, or apply pressure to the E5CN as it may
cause it to deform and deteriorate during use or storage.
17. Avoid using the E5CN in places near a radio, television set, or wireless in-
stallation. These devices can cause radio disturbances which adversely af-
fect the performance of the E5CN.

• If necessary, a more comprehensive alarm function can be achieved by
setting the “standby sequence”, “alarm hysteresis”, “close in alarm/open
in alarm” and Alarm latch ON/OFF parameters.
• When the input error output is set to “ON”, alarm output 1 turns ON when
an input error occurs.
Control adjustment • Optimum PID constants can be set easily by AT (auto-tuning) and ST
(self-tuning).
Event input • When the option event input unit E53-CNHB is mounted in the E5CN, the
following functions can be achieved by event input:
Set point selection (multi-SP max. 4 points) and run/stop
HBA • The heater burnout alarm (HBA) function is supported when the option
unit (E53-CNHB or E53-CNH03) is mounted in the E5CN.
Communications function • Communications according to CompoWay/F* and Sysway are supported
when the option communications unit E53-CNH03 is mounted in the
E5CN.
Communications are carried out over the RS-485 interface.
Note CompoWay/F is a general-purpose serial communications-based unified com-
munications procedure developed by OMRON. CompoWay/F uses com-
mands compliant with the well-established FINS, together with a unified frame
format on OMRON programmable controllers to facilitate communications
between personal computers and components.

1-3 How Setup Levels Are Configured and Operating the Keys
on the Front Panel
Parameters are divided into groups, each called a “level”. Each of the set val-
ues (setup items) in these levels are called a “parameter.” The parameters on
the E5CN are divided into the following seven levels:
: Indicates items that can be set.
Of these levels, the initial setting level, communications setting level,
advanced function setting level and calibration level can be used only when
control has stopped. Note that controller outputs are stopped when any of
these four levels are selected.

How Setup Levels Are Configured and Operating the Keys on the Front Panel Section 1-3
Protect level • To move the mode at this level, simultaneously press the and
keys for at least three seconds in the operation level or adjustment level.
This level is for preventing unwanted or accidental modification of param-
eters. Protected levels will not be displayed, and so the parameters in that
level cannot be modified.
Operation level • This level is displayed when you turn the power ON. You can move to the
protect level, initial setting level and adjustment level from this level.
• Normally, select this level during operation. During operation, the process
value, set point and manipulated variable can be monitored, and the
alarm value and upper- and lower-limit alarms can be monitored and
modified.
Adjustment level • To move the mode at this level, press the key for less than one sec-
ond.
• This level is for entering set values and offset values for control. This level
contains parameters for setting the AT (auto-tuning), communications
writing enable/disable, hysteresis, multi-SP, input shift values, heater
burnout alarm (HBA) and PID constants. You can move to the top param-
eter of the initial setting level and operation level from here.
Initial setting level • To move the mode at this level, press the key for at least three sec-
onds in the operation level or adjustment level. The PV display flashes
after one second. This level is for specifying the input type, selecting the
control method, control period, setting direct/reverse action and alarm
type. You can move to the advanced function setting level or communica-
tions setting level from this level. To return to the operation level, press the
key for at least one second. To move to the communications setup
level, press the key for less than one second.
Advanced function setting
level • To select this level, you must enter the password (“-169”) in the initial set-
ting level.
• You can move to the calibration level only from this level.
• This level is for setting the automatic return of display mode, MV limitter,
event input assignment, standby sequence, alarm hysteresis, ST (self-
tuning) and for moving to the user calibration level.
Communications setting
level • To move the mode at this level, press the key for less than one sec-
ond in the initial setting level. When the communications function is used,
set the communications conditions in this level. Communicating with a
personal computer (host computer) allows set points to be read and writ-
ten, and manipulated variables to be monitored.
Note This level is available if communications card (E53-CNH03) is fitted
to the unit.
Calibration level • To move the mode at this level, you must enter the password “1201” in the
advanced function setting level. This level is for offsetting deviation in the
input circuit.
• You cannot move to other levels by operating the keys on the front panel
from the calibration level. To cancel this level, turn the power OFF then
back ON again.

1-3-1 Selecting parameters
• To select parameters in each level, press the key. Each press of the
key advances to the next parameter. For details on each parameter,
see Section 5.
1-3-2 Fixing settings
• If you press the key at the final parameter, the display returns to the
top parameter for the current level.
• To change parameter settings or setup, specify the setting using the
or keys, and either leave the setting for at least two seconds or press
the key. This fixes the setting.
• When another level is selected, the parameter and setting on the display
are fixed.
• When you turn the power OFF, you must first fix the settings or parameter
setup (by pressing the key). The settings and parameter setup are
sometimes not changed by merely pressing the or keys.
1-4 Communications Function
The E5CN can be provided with a communications function that allows you to
check and set controller parameters on a host computer. If the communica-
tions function is required, mount the option unit E53-CNH03 in the E5CN. For
details on the communications function, see the separate “Communications
Functions User’s Manual.”
Follow the procedure below to move to the communications setting level.
1,2,3... 1. Press the key for at least three seconds in the “operation level”. The
level moves to the “initial setting level”.
2. Press the key for less than one second. The “initial setting level”
moves to the “communications setting level”.
