NOTICE
Be sure to observe these precautions to ensure safe use.
(1) Do not wire unused terminals.
(2) Be sure to wire properly with correct polarity of terminals.
(3) To reduce induction noise, separate the highĆvoltage or largeĆcurrent power lines from other lines,
and avoid parallel or common wiring with the power 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 have removed the terminal plate, 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 prodĆ
uct.
(8) Use AWG24 to AWG14 leads for terminal Nos.1 to 6 and AWG28 to AWG22 leads for terminal
Nos.7 to 9 (with lead cover peel back allowance of 5 or 6 mm).
(9) Allow as much space as possible between the E5GN and devices that generate powerful highĆfreĆ
quency noise (e.g. highĆfrequency welders, highĆfrequency sewing machines) or surges.
(10) When executing selfĆtuning, turn the load (e.g. heater) ON simultaneously or before you turn the
E5GN ON. If you turn the E5GN ON before turning the load ON, correct selfĆtuning 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 E5GN. Also, make sure that the rated voltage is attained within two seconds
of turning the power ON.
(12) Attach a surge suppresser or noise filter to peripheral devices that generate noise (in particular,
motors, transformers, solenoids, magnetic coils or other equipment that have an inductance comĆ
ponent).
(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 E5GN.
(14) Use within the following temperature and humidity ranges:
• Temperature: Ć10 to 55_C, Humidity: 25 to 85% (with no icing or condensation)
If the E5GN is installed inside a control board, the ambient temperature must be kept to under
55_C, including the temperature around the E5GN.
If the E5GN is subjected to heat radiation, use a fan to cool the surface of the E5GN to under 55_C.
(15) Store within the following temperature and humidity ranges:
• Temperature: Ć25 to 65_C, Humidity: 25 to 85% (with no icing or condensation)
(16) Never place heavy objects on, or apply pressure to the E5GN as it may cause it to deform and deteriĆ
orate during use or storage.
(17) Avoid using the E5GN in places near a radio, television set, or wireless installation. These devices
can cause radio disturbances which adversely affect the performance of the E5GN.

output is used as alarm 2 output.

F Alarms • Alarms are supported on the E5GNĆ 1 j jj . Set the alarm type and
alarm value, or upperĆ and lowerĆlimit alarms.
• If necessary, a more comprehensive alarm function can be achieved by
setting the standby sequence, alarm hysteresis and 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.

F Control • Optimum PID constants can be set easily by AT (autoĆtuning) and ST
adjustment (selfĆtuning).

F Communications • Communications according to CompoWay/F *1 and Sysway*2 are supĆ
function j j
ported on the E5GNĆ 03 .
Communications are carried out over the RSĆ485 interface.

*1 CompoWay/F is a generalĆpurpose serial communicationsĆbased unified

communications procedure developed by OMRON. CompoWay/F uses
commands compliant with the wellĆestablished FINS, together with a uniĆ
fied frame format on OMRON programmable controllers to facilitate
communications between personal computers and components.
*2 Sysway communication does not support alarm 3 output.

2.3 Requests at Installation

J To ensure Use the temperature in the following operating environment:
Temperature : -10 to +55°C (icing and condensation not allowed)
prolonged use
Humidity : 25 to 85%
When the temperature controller is incorporated in a control panel, make
sure that the controller's ambient temperature and not the panel's ambiĆ
ent temperature does not exceed 55°C.
The life of electronic equipment such as temperature controllers is inĆ
fluenced not only by the life determined by the relay switching count but
also by the life of the electronic components used internally. The service
life of components is dependent on the ambient temperature: the higher
the ambient temperature becomes, the shorter the service life becomes,
and vice versa. For this reason, the service life of the temperature controlĆ
ler can be extended by lowering its internal temperature.
Gang-mounting two or moretemperature controllers,or mountingtemperĆ
ature controllers aboveeach other may causeheat to build up inside thetemĆ
perature controllers, which will shorten their service life. When mounting
temperature controllers like this, forced cooling measures such as a cooling
fan for cooling thetemperature controllers must betaken into consideration.
Prevent only the terminal block from being cooled. Otherwise, this may
result in a measurement error.

J To reduce the To reduce induction noise, the leads on the temperature controller's terĆ
influence of noise minal block must be wired separately from large-voltage/large-current
power leads. Also, avoid wiring leads in parallel with power leads or in the
same wiring path. Other methods such as separating conduits and wiring
ducts, or using shield wire are also effective.
Attach a surge absorber or noise filter to peripheral equipment that generĆ
ates noise (in particular, motors, transformers, solenoids, or other equipĆ
ment that has a magnetic coil or other 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.
Also, install the temperature controller as far away as possible from equipĆ
ment that generates strong, high frequency (e.g. high-frequency welders,
high-frequency sewing machines) or surges.

J To ensure When the thermocouple leads are extended, be sure to use a compensating
lead wire matched to the type of thermocouple.
high-precision
When the platinum resistance detector leads are extended, use the lead
measurement having the smallest resistance to equalize the resistance of the three leads.
Install the temperature controller so that it is horizontal.
If there is a large error in the measurement values, make sure that input
compensation has been set correctly.

3.4 Selecting PID Control or ON/OFF Control

The E5GN supports two control methods, 2ĆPID control and ON/OFF
control. The control method is selected by the PID / ON/OFF parameter
in the initial setting level. When this parameter is set to , 2ĆPID
control is set, and when set to , ON/OFF control is set (default).

F 2ĆPID control PID control is set by AT (autoĆtuning), ST (selfĆtuning) or manual setup.
For PID control, set the PID constants in the proportional band (P),
integral time (I) and derivative time (D) parameters.

F ON/OFF control In ON/OFF control, the control output is turned ON when the process
value is lower than the current set point, and the control output is turned
OFF when the process value is higher than the current set point (reverse
operation).

3.5 Setting Output Specifications

3.5 Setting Output Specifications

J Control period • Set the output period (control period). Though a shorter period provides
Control better control performance, we recommend setting the control period to
period 20 seconds or more taking the life expectancy in the case of relay output
(OUT1) into consideration. If necessary, readjust the control period by trial
operation, for example, when the control period parameters are set to
their defaults.
• Set the control period in the control period (OUT1) parameter (initial
setting level). Default is 20 seconds.

J Direct/reverse • Direct operation refers to control where the manipulated variable is
increased according to the increase in the process value. Alternatively,
operation
reverse operation refers to control where the manipulated variable is
decreased according to the increase in the process value.

Manipulated variable Manipulated variable
100% 100%

0% 0%
Low temperature Set value High temperature Low temperature Set value High temperature
Direct operation Reverse operation
For example, when the process value (PV) (temperature) is lower than
the set point (SP) (temperature) in a heating control system, the manipĆ
ulated variable increases by the difference between the PV and SP valĆ
ues.
Accordingly, this becomes reverse operation in a heating control sysĆ
tem, or alternatively, direct operation in a cooling control system.
• Direct/reverse operation is set in the direct/reverse operation parameĆ
ter (initial setting level). The direct/reverse operation parameter
default is reverse operation.

3.7 Executing ON/OFF Control

In ON/OFF control, the control output turns OFF when the currently
controlled temperature reaches a preset set point. When the manipulated
variable turns OFF, the temperature begins to fall and the control output
turns ON again. This operation is repeated at a certain point. At this time,
how much the temperature must fall before control turns ON again is
determined by the hysteresis (OUT1) parameter. Also, how much the
manipulated variable must be adjusted in response in the increase or
decrease in the process value is determined by direct/reverse operation
parameter.

J ON/OFF control • Switching between 2ĆPID control and ON/OFF control is carried out by
the PID / ON/OFF parameter (initial setting level). When this paramĆ
eter is set to , 2ĆPID control is selected, and when set to ,
ON/OFF control is selected. Default is .

F Hysteresis • In ON/OFF control, the hysteresis is used as a differential for switching
the output ON when the temperature moves away from the required set
point, and is used to give stability around the set point.
• The hysteresis width is called the hysteresis band. The control output
(OUT1) function is set by hysteresis (OUT1).
• In standard control (heating or cooling control), the hysteresis
(OUT1) setting is used as the hysteresis setting in the adjustment level
regardless of the control type, heating control or cooling control.

3.8 Determining PID Constants (AT, ST, manual setup)

J AT (autoĆtuning) • When you execute autoĆtuning, the optimum PID constants for the set
point during program execution are automatically set by forcibly changĆ
ing the manipulated variable to calculate the characteristics (called the
limit cycle method) of the control target.
• To execute AT (autoĆtuning), specify : AT execute, and to cancel AT
(autoĆtuning), specify : AT cancel.
• AT (autoĆtuning) cannot be executed during ON/OFF control or STOP.
• The result of AT (autoĆtuning) is mirrored in the proportional band
(P), integral time (I) and derivative time (D) parameters in the
adjustment level.

3.10 Requests during Operation

1) About two seconds is required for outputs to turn ON when the power

is turned ON. Take this into consideration when the temperature conĆ

troller is incorporated into a sequence circuit.

2) Allow at least 30 minutes for warming up.

3) When self-tuning is used, turn the temperature controller and load

(e.g. heater) ON simultaneously or turn the load ON before the temĆ

perature controller. If the load is turned ON before the temperature

controller, correct self-tuning and optimum control are no longer

possible.

When operation is started after warm-up, turn the power OFF once

after warm-up is completed, and then turn the temperature controlĆ

ler and load ON simultaneously (Instead of turning the temperature
.

controller power ON again, moving from the STOP to the RUN mode

also is possible.)

4) The temperature controller may be subject to the influence of radio

interference if used near a radio, TV or wireless equipment.

J How to calculate input shift values (2Ćpoint shift)
When the nonĆcontact temperature sensor model ES1A is connected to the
E5GN, an offset of several to several tens of a degree can occur.
For this reason, offset the readout value by 1Ćpoint or 2Ćpoint shift as
described in this item. This offset occurs as a bias current for detecting
controller sensor error flows to the output impedance of the nonĆcontact
temperature sensor. 2Ćpoint shift can be carried out only on nonĆcontact
temperature sensors, and cannot be set for other input types.
[Preparations]

(1) Set to the temperature range matching the input specifications of the
nonĆcontact temperature sensor. (ES1A is supported only in thermoĆ
couple input types on the E5GN.)
(2) Prepare a thermometer capable of measuring the temperature of the
control target as shown in Figure 1 so that 1Ćpoint shift or 2Ćpoint
shift can be carried out.

sequence
on, the alarm output is active for future alarm conditions.
• For example, in a standard heating application, if you used the standard
low alarm, the alarm would be active from switching the controller
ON. However, with Standby Sequence, the alarm output is disabled
during the first warmup, and the temperature has to rise above the
alarm set point before the alarm can become active. Then, if the temperĆ
ature falls below the alarm set point, the output is active.

F Restart • The standby sequence is canceled when an alarm is output. It is, howĆ
ever, restarted later by the standby sequence parameter (advanced
function setting level).
For details, see the standby sequence parameter in Chapter 5, PaĆ
rameters.

J Alarm latch • Alarm latch is a function where alarm output once turned ON stays
ON regardless of the temperature.
• The alarm latch can be canceled by turning the power OFF. (Note, howĆ
ever, that it can also be canceled by switching to the initial setting level,
communications setting level, advanced function setting level or calĆ
ibration level.

Whereas the entire input range is shifted by a fixed rate (1Ćpoint shift) in the temperature input
shift parameter, the input range is shifted by two points (2Ćpoint shift) at the upper and lower
limits. 2Ćpoint shift enables more accurate offset of the input range compared with 1Ćpoint shift,

Proportional band The control must be 2ĆPID control.

Integral time
Derivative time

This parameter sets the PID parameters. Note that PID is automatically set when AT and ST are
executed.

Proportional action : P refers to control in which the MV is proportional to the deviĆ
ation (control error).
Function Integral action : I gives a control action that is proportional to the time integral
of the control error. With proportional control, there is norĆ
mally an offset (control error). So, proportional action is used
in combination with integral action. As time passes, this conĆ
trol error disappears, and the set point comes to agree with the
control temperature (process value).
Derivative action : D gives a control action that is proportional to the time derivaĆ
tive of the control error. As proportional control and integral
control correct for errors in the control result, the control sysĆ
tem will be late in responding to sudden changes in temperaĆ
ture. Derivative action enables control that is proportional to
a predicted process output to correct for future error.

6.2 User Calibration

6.2 User Calibration

The E5GN is correctly calibrated before it is shipped from the factory and

normally need not be calibrated by the user.

If, however it must be calibrated by the user use the parameters for caliĆ
, ,

brating temperature input and analog input.

However, note that OMRON cannot ensure the results of calibration by

the user.

Also, calibration data is overwritten with the latest settings. The default

calibration settings cannot be returned to after user calibration.

F Calibrating input When the user calibrates the E5GN, the input type currently selected in

parameters is calibrated. The following 24 input types can be calibrated.

• Thermocouple : 14 types

• NonĆcontact temperature sensor : 4 type

• Analog input : 1 type

• Platinum resistance thermometer : 5 types

F Registering The new calibration data for each item is temporarily registered. It can be

calibration data officially registered as calibration data only when all items have been caliĆ

brated to new values. So, be sure to temporarily register all items when

you calibrate the E5GN.

When calibration data is registered, it is registered regardless of whether

or not the E5GN has been calibrated by the user.

Prepare separate measuring devices and equipment for calibration. For

details on how to handle measuring devices and equipment, refer to the

respective instruction manuals.

ERROR DISPLAY
When an error has occurred, the No.1 display alternately indicates error
codes together with the current display item.
This section describes how to check error codes on the display, and the
actions you must take to remedy the problem.

Input error

F Meaning The input value has exceeded the control range.
* Control range
Platinum resistance : Temperature setting lower limit -20_C to
thermometer, temperature setting upper limit +20_C
thermocouple input (temperature setting lower limit -40_F to
temperature setting upper limit +40_F)
ESIA input : Same as input indication range
Analog input : -5% to 105% of scaling range

F Action Check the wiring of inputs for miswiring, disconnections, and shortĆcirĆ
cuits and the input type.
If no abnormality is found in the wiring and input type, turn the power
OFF then back ON again. If the display remains the same, the E5GN must
be repaired. If the display is restored, then a probable cause can be electriĆ
cal noise affecting the control system. Check for electrical noise.

F Operation at error After the error occurs, the error is displayed, and control output functions
turn OFF.
Alarm outputs function as if the upper limit value has been exceeded.
When output input error (advanced function level) is set to ON, the
alarm 1 output turns ON when an input error occurs.
An error message is displayed when process value or PV/SP are disĆ
played.

Memory error

F Meaning Internal memory operation is in error.

F Action First, turn the power OFF then back ON again. If the display remains the
same, the E5GN must be repaired. If the display is restored, then a probĆ
able cause can be electrical noise affecting the control system. Check for
electrical noise.

F Operation at error Control output and alarm output turn OFF.
