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.

Ă•The following input sensors can be connected for temperature input:
Thermocouple : K, J, T, E, L, U, N, R, S, B
NonĆcontact temperature sensor ES1A
: K 10 to 70_C), K 60 to 120_C), K 115 to 165_C),
ĂĂK160 to 260_C
Platinum resistance thermometer
: JPt100, Pt100
Analog input : 0 to 50 mV
Ă•Control output is either relay or voltage output depending on the model
of E5GN.
Ă•Alarms are supported on the E5GNĆj1jj. Set the alarm type and
alarm value, or upperĆ and lowerĆlimit alarms.
Ă•If necessary, a more comprehensive alarm function can be achieved by
setting the standby sequence", alarm hysteresis" and close in alarm/
open in alarm" parameters.
Ă•Optimum PID constants can be set easily by AT autoĆtuning) and ST
selfĆtuning).
Ă•Communications according to *CompoWay/F are supported on the
E5GNĆj03j.
Communications are carried out over the RSĆ485 interface.
* 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

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
values setup items) in these levels is called a parameter." The parameĆ
ters on the E5GN are divided into the following seven levels:
When the E5GN is turned ON, all items in the display light for about one
second.

Ă•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
parameters. Protected levels will not be displayed, and so the parameĆ
ters in that level cannot be modified.
Ă* The key pressing time can be changed in protect level move time".
Ă•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.
Ă•Normally, select this level during operation. During operation, the proĆ
cess value, set point and manipulated variable can be monitored, and the
alarm value and upperĆ and lowerĆlimit alarms can be monitored and
modified.
Ă•To move the mode at this level, press the key for less than one
second.
Ă•This level is for entering set values and offset values for control. This
level contains parameters for setting the AT autoĆtuning), communicaĆ
tions writing enable/disable, hysteresis, multiĆSP, input shift values and
PID constants. You can move to the top parameter of the initial setting
level and operation level from here.
Ă•To move the mode at this level, press the key for at least three seconds
in the operation level or adjustment level or adjustment level. The PV disĆ
play flashes after one second.
Ă•This level is for specifying the input type, selecting the control method,
control period, setting direct/reverse action and alarm type. When you
move to the operation level from the initial setting level, all items in the
display light.)
Ă•You can move to the advanced function setting level or communications
setting level from this level. To return to the operation level, press the
key for at least one second. To move to the communication setting
level, press the key for less than one second.
Ă•To move the mode at this level, you must enter the password Ć169") in
the initial setting level.
Ă•You can move to the calibration level only from this level.
Ă•This level is for setting the automatic return of display mode, MV limitĆ
ter, standby sequence, alarm hysteresis, ST selfĆtuning) and for moving
to the user calibration level.
Ă•To move the mode at this level, press the key for less than one second
in the initial setting level.
Ă•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 written, and manipulated
variables to be monitored.

Ă•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 characteristics on the input circuit.
Ă•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.
Ă•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 Chapter 5.
