■Communications Specifications
Note: The baud rate, data bit length, stop bit length, or vertical parity can be individually set using the communications setting level.
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 ter-
minals to a device without any exposed current-carrying parts or to
a device with standard insulation suitable for the maximum operat-
ing voltage of the power supply I/O section.

Mounting separately does not allow waterproofing.
*When carrying out maintenance on the E5GN, only the terminal plate
can be drawn out with the terminal leads still attached.
•Insert the Controller through the hole in the panel from the front and push
the adapter on from the rear. Push the adapter up to the back of the panel
ensuring that the controller is pushed all the way in, removing any gap
between the Controller, panel, and 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 packing
onto the E5GN.
•When two or more E5GN Controllers are mounted, make sure that the
surrounding temperature does not exceed the allowable operating
temperature given in the specifications.

Operation
■Specification Setting after Turning ON Power
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.
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 moni-
tored 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.
Protect Level
To select this level, simultaneously press the and keys for at
least 3 seconds. This level is to prevent unwanted or accidental mod-
ification 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 lim-
iter, 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.

Note: 1. Of these levels, the initial setting level, communications
setting level, advanced function setting level and cali-
bration level can be used only when control has stop-
ped. 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.

Specification Setting after Turning ON Power
Initial Setting Level
This level is used for setting basic specifications of the Temperature
Controller. Using this level, set the input type for selecting the input to
be connected such as the thermocouple or platinum resistance ther-
mometer and set the range of set point and the alarm mode.
The move from the operation level to the initial setting level, press
key for three seconds or more.
The initial setting level is not displayed when “initial/communications
protection” is set to “2.” This initial setting level can be used when
“initial setting/communications protection” is set to “0” or “1.”

4. Press the or keys to change the parameter setups.
Note: On the E5GN, the Key is the Key.
Set each communications parameter to match those of the communi-
cating personal computer.
Communications Unit No. (u-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 (bps)
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.
Data Bits (len)
Use this parameter to change the communications data bit length to
7 bits or 8 bits.
Stop Bits (sbit)
Use this parameter to change the communications stop bit to 1 or 2.
Communications Parity (prty)
Use this parameter to set the communications parity to None, Even,
or Odd.
Troubleshooting
When an error occurs, an error code will be displayed on the No. 1 display. Check the contents of an error and take appropriate countermeasures.
Note 1. If the input is within the range for which control is possible but outside the displayable range (–1999 (–199.9) to 9999 (999.9)), will
be displayed if the value is less than –1999 (–199.9), and will be displayed if it is greater than 9999 (999.9). Control output and alarm
output will operate normally for either of these displays. Refer to the relevant User’s Manual for details on the ranges for which control is
possible.
2. These errors are displayed only when the Controller is set to display the present value or the present value and the set value. They are not
displayed in other statuses.

Safety Precautions
Note: 1. An SELV circuit is one separated from the power supply with
double insulation or reinforced insulation, that does not
exceed 30 V r.m.s. and 42.4 V peak or 60 VDC.
2. A class 2 power supply is one tested and certified by UL as
have the current and voltage of the secondary output
restricted to specific levels.
Do not touch the terminals while power is being supplied.
Doing so may occasionally result in minor injury due to
electric shock.
Do not allow pieces of metal, wire clippings, or fine
metallic shavings or filings from installation to enter the
product. Doing so may occasionally result in electric
shock, fire, or malfunction.
Do not use the product where subject to flammable or
explosive gas. Otherwise, minor injury from explosion
may occasionally occur.
Do not leave the conversion cable connected to the
product. Malfunction may occur due to noise in the cable.
Do not use the Temperature Controller or Conversion
Cable if it is damaged. Doing so may occasionally result
in minor electric shock or fire.
Never disassemble, modify, or repair the product or touch
any of the internal parts. Minor electric shock, fire, or
malfunction may occasionally occur.
CAUTION - Risk of Fire and Electric Shock
a) This product is UL listed as Open Type Process
Control Equipment. It must be mounted in an
enclosure that does not allow fire to escape externally.
b) More than one disconnect switch may be required to
de-energize the equipment before servicing the
product.
c) Signal inputs are SELV, limited energy. (See note 1.)
d) Caution: To reduce the risk of fire or electric shock, do
not interconnect the outputs of different Class 2
circuits. (See note 2.)
If the output relays are used past their life expectancy,
contact fusing or burning may occasionally occur.
Always consider the application conditions and use the
output relays within their rated load and electrical life
expectancy. The life expectancy of output relays varies
considerably with the output load and switching
conditions.
Tighten the terminal screws properly. Tighten them to a
torque of 0.24 N·m (2.5 kgf·cm) max. on terminals 1 to 6.
Tighten them to a torque of 0.13 N·m (1.4 kgf·cm) max.
on terminals 7 to 9. Loose screws may cause
malfunction.
Set the parameters of the product so that they are
suitable for the system being controlled. If they are not
suitable, unexpected operation may occasionally result in
property damage or accidents.
A malfunction in the product may occasionally make
control operations impossible or prevent alarm outputs,
resulting in property damage. To maintain safety in the
event of malfunction of the product, take appropriate
safety measures, such as installing a monitoring device
on a separate line.
!CAUTION A semiconductor is used in the output section of long-life
relays. If excessive noise or surge is impressed on the
output terminals, a short-circuit failure is likely to occur. If
the output remains shorted, fire will occur due to
overheating of the heater or other cause. Take measures
in the overall system to prevent excessive temperature
increase and to prevent fire from spreading.
Do not allow pieces of metal or wire cuttings to get inside
connectors. Failure to do so may occasionally result in
minor electric shock, fire, or damage to equipment.

Digital Temperature Controllers E5GN 17
Precautions for Safe Use
Be sure to observe the following precautions to prevent malfunction
or adverse affects on the performance or functionality of the product.
Not doing so may occasionally result in faulty operation.
1. This product is specifically designed for indoor use only.
Do not use this product in the following places:
•Places directly subject to heat radiated from heating equipment.
•Places subject to splashing liquid or oil atmosphere.
•Places subject to direct sunlight.
•Places subject to dust or corrosive gas (in particular, sulfide gas
and ammonia gas).
•Places subject to intense temperature change.
•Places subject to icing and condensation.
•Places subject to vibration and large shocks.
2. Use and store the product within the rated ambient temperature
and humidity.
Gang-mounting two or more Temperature Controllers, or
mounting Temperature Controllers above each other may cause
heat to build up inside the Temperature Controllers, which will
shorten their service life. In such a case, use forced cooling by
fans or other means of air ventilation to cool down the
Temperature Controllers.
3. To allow heat to escape, do not block the area around the
product. Do not block the ventilation holes on the product.
4. Be sure to wire properly with correct polarity of terminals.
5. Use the specified size (M3.5, width 7.2 mm or less) crimped
terminals for wiring. To connect bare wires to the terminal block,
use stranded or solid copper wires with a gage of AWG24 to
AWG14 (equal to a cross-sectional area of 0.205 to 2.081 mm2).
(The stripping length is 5 to 6 mm.) Up to two wires or two crimp
terminals can be inserted into a single terminal.
6. Do not wire the terminals that are not used.
7. To avoid inductive noise, keep the wiring for the product’s
terminal block away from power cables carry high voltages or
large currents. Also, do not wire power lines together with or
parallel to product wiring. Using shielded cables and using
separate conduits or ducts is recommended.
Attach a surge suppressor or noise filter to peripheral devices
that generate noise (in particular, motors, transformers,
solenoids, magnetic coils, or other equipment that have an
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 product.
Allow as much space as possible between the product and
devices that generate powerful high frequencies (high-frequency
welders, high-frequency sewing machines, etc.) or surge.
8. Use this product within the rated load and power supply.
9. Make sure that the rated voltage is attained within two seconds
of turning ON the power using a switch or relay contact. If the
voltage is applied gradually, the power may not be reset or output
malfunctions may occur.
10. 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.
11. When executing self-tuning, turn ON power to the load (e.g.,
heater) at the same time as or before supplying power to the
product. If power is turned ON to the product before turning ON
power to the load, self-tuning will not be performed properly and
optimum control will not be achieved.
12. A switch or circuit breaker must be provided close to the product.
The switch or circuit breaker must be within easy reach of the
operator, and must be marked as a disconnecting means for this
unit.
13. Always turn OFF the power supply before pulling out the interior
of the product, and never touch nor apply shock to the terminals
or electronic components. When inserting the interior of the
product, do not allow the electronic components to touch the
case.
14. Do not use paint thinner or similar chemical to clean with. Use
standard grade alcohol.
15. Design the system (e.g., control panel) considering the 2
seconds of delay that the product's output to be set after power
ON.
16. The output may turn OFF when shifting to certain levels. Take
this into consideration when performing control.
17. The EEPROM has a limited write life. When overwriting data
frequently, e.g., via communications, use RAM Mode.
Precautions for Correct Use
Service Life
1. Use the product within the following temperature and humidity
ranges:
Temperature: –10 to 55°C (with no icing or condensation)
Humidity: 25% to 85%
If the product is installed inside a control board, the ambient
temperature must be kept to under 55°C, including the
temperature around the product.
2. The service life of electronic devices like Temperature Controllers
is determined not only by the number of times the relay is
switched but also by the service life of internal electronic
components. Component service life is affected by the ambient
temperature: the higher the temperature, the shorter the service
life and, the lower the temperature, the longer the service life.
Therefore, the service life can be extended by lowering the
temperature of the Temperature Controller.
3. When two or more Temperature Controllers are mounted
horizontally close to each other or vertically next to one another,
the internal temperature will increase due to heat radiated by the
Temperature Controllers and the service life will decrease. In such
a case, use forced cooling by fans or other means of air
ventilation to cool down the Temperature Controllers. When
providing forced cooling, however, be careful not to cool down the
terminals sections alone to avoid measurement errors.
Measurement Accuracy
1. When extending or connecting the thermocouple lead wire, be
sure to use compensating wires that match the thermocouple
types.
2. When extending or connecting the lead wire of the platinum
resistance thermometer, be sure to use wires that have low
resistance and keep the resistance of the three lead wires the
same.
3. Mount the product so that it is horizontally level.
4. If the measurement accuracy is low, check to see if input shift has
been set correctly.
Waterproofing
The degree of protection is as shown below. Sections without any
specification on their degree of protection or those with IP@0 are not
waterproof.
Front panel: NEMA4X for indoor use (equivalent to IP66)
Rear case: IP20, Terminal section: IP00
Operating Precautions
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
in a sequence circuit.
2. When using 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.
3. 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.)

18 Digital Temperature Controllers E5GN
4. Avoid using the Controller in places near a radio, television set, or
wireless installing. These devices can cause radio disturbances
which adversely affect the performance of the Controller.
Mounting
1. Insert the E5GN into the mounting hole in the panel from the
front.
2. Push the adapter along the E5GN body from the terminals up to
the panel, and secure it temporarily.
3. Tighten the two fixing screws on the adapter. When tightening
screws, tighten the two screws alternately keeping the torque to
within approximately 0.29 to 0.39 N·m.
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 terminals
to unlock the terminal plate and pull upwards.
2. Draw out the terminal plate as it is.
3. Before you insert the terminal plate again, make sure that the pins
match the positions of the holes in the terminal plate.
