is pushed all the way in, and remove any gap between the Controller, the panel, and the
adapter. Finally, use the two screws on the adapter to secure the unit in place.
•To mount the E5GN so that it is waterproof, insert the waterproof seal onto the E5GN.
•When two or more E5GN Controllers are mounted, make sure that the surrounding

REMOVING AND ATTACHING THE
TERMINAL PLATE
The E5GN can be replaced by removing the terminal plate.
1. Press down hard on the fasteners on both sides of the termi-
nals to unlock the terminal plate and pull upward.
2. Pull to remove the terminal plate.
3. Before you insert the terminal plate again, make sure that the
pins match the positions of the holes in the terminal plate.

WIRING TERMINALS
The voltage output (control output) is not electrically insulated
from the internal circuits. When using a grounding thermocouple,
do not connect the control output terminals to the ground. If the
control output terminals are connected to the ground, errors will
occur in the measured temperature values, as a result of leakage
current.
Standard insulation is applied to the power supply I/O sections. If
reinforced insulation is required, connect the input and output
terminals to a device without any exposed current-carrying parts
or to a device with standard insulation suitable for the maximum
operating voltage of the power supply I/O section.

OUTLINE OF OPERATION PROCEDURES
Key Operation
In the following descriptions, all the parameters are introduced in the display sequence. Some parameters may not be displayed
depending on the protect settings and operation conditions.
Note: 1. 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 control is
stopped when these four levels are selected. When
switched back to the operation level from one of these
levels, control will start.
2. For the calibration mode, refer to the relevant

DESCRIPTION OF EACH LEVEL
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 select this level, press the key once for less than one
second.
This level is for entering set values and offset values for control.
This level contains parameters for setting the set values, 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 parameter of the operation
level or initial setting level from here.
Initial Setting Level
To select this level, press the key for at least three seconds in
the operation level. 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 communications setting level from this initial
setting level. To return to the operation level, press the key for
at least one second. To move to the communications setting
level, press the key once for less than one second.

E5GN
E5GN
Protect Level
To select this level, simultaneously press the and keys
for at least one second. This level is to prevent unwanted or
accidental modification of parameters. Protected levels will not be
displayed, and so the parameters in that level cannot be
modified.
Communications Setting Level
To select this level, press the key once for less than one
second 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 written, and manipulated variables to be
monitored.
Advanced Function Setting Level
To select this level, you must enter the password (“-169”) in the
initial setting level.
You can move only to the calibration level from this level.
This level is for setting the automatic return of display mode, MV
limiter, event input assignment, standby sequence, alarm
hysteresis, ST (self-tune) and to move to the user calibration
level.
Calibration Level
To select 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. Press the key for at least three seconds in the “operation

Communications Unit No. (  )
When communicating with the host computer, the unit number
must be set in each Temperature Controller so that the host
computer can identify each Temperature Controller. The number
can be set in a range from 0 to 99 in increments of 1. The default
setting is 1. When using more than one Unit, be careful not to
use the same number twice. Duplicate settings will cause
malfunction. This value becomes valid when the power is turned
OFF and ON again.
Baud Rate (  )
Use this parameter to set the speed of communications with the
host computer. It can be set to one of the following values; 1.2
(1200 bps), 2.4 (2400 bps), 4.8 (4800 bps), 9.6 (9600 bps), and
19.2 (19200 bps).
This setting becomes valid when the power is turned OFF and
ON again.

Use this parameter to change the communications data bit length
to7bitsor8bits.
Stop Bits (  )
Use this parameter to change the communications stop bit to 1 or

Memory error First, turn the power OFF then back ON again. If the display remains the same, the
Unit must be repaired. If the display is restored, then a probable cause can be external
noise affecting the control system. Check for external noise.

HB error First, turn the power OFF then back ON again. If the display remains the same, the
controller must be repaired. If the display is restored, then a probable cause can be
electrical noise affecting the control system. Check for electrical noise.
Note: Error will be displayed only when the display is set for the PV or PV/SP.
Fuzzy Self-tuning
The fuzzy self-tuning (ST) is a function that automatically calculates an optimum PID constant depending on items to be controlled.

FEATURE
The Temperature Controller determines when to execute this fuzzy self-tuning.

FUNCTIONS
SRT: Performs PID tuning according to the step response method when the SP is changed.
LCT: Performs PID tuning according to the limit cycle method when the SP is changed.
Requirements for SRT Functionality
The ST will be executed according to the step response method when the following conditions are satisfied when operation is started or
when the SP is changed.
When operation is started When SP is changed
1. The SP at the startup is different from the SP at the time the
previous SRT was executed. (See Note.)
2. The temperature upon startup is smaller than the SP in the
reverse operation and larger than the SP in the direct
operation.
3. Restarting of operation is not due to an input error.
Note: The “SP that existed when the previous SRT was
executed” refers to the SP used for obtaining the PID
constant in the previous SRT.
1. The SP after change is different from the SP at the time the pre-
vious SRT was executed. (See Note.)
2. In the reverse operation, the value obtained by deducting the SP
before change from the SP after change is larger than the ST
stable range. In the direct operation, the value obtained by
deducting the SP after change from the SP before change is
larger than the ST stable range.
3. The SP change width is larger than the current proportional band
x1.27+4.
4. The temperature is in the stable state. (It can be in the balanced
state if no output is generated when the power is turned ON.)
If the SP is changed while SRT is being executed and if SRT completion conditions are satisfied, no PID change will take place.
Stabilization State
Measured values remain in the stable range for a certain period
of time.
Balanced State
Output is 0% for 60 seconds and measured values fluctuate
within the width of the stable range.
