■ Safety Precautions
Do not touch the terminals while power is being supplied. Doing
so may occasionally result in minor injury due to electric shock.
Use a power supply that complies with the reinforced insulation
specified in IEC 60664 for the EJ1 external power supply or the
power supply connected to the EJ1. If non-compliant power
supplies are used, electric shock may occasionally result in minor
injury.
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.
Never disassemble, modify, or repair the product or touch any of
the internal parts. Minor electric shock, fire, or malfunction may
occasionally occur.
CAUTION
Tighten the terminal screws to between 0.40 and
0.56 N·m. Loose screws may occasionally result in fire.
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.
Gradient temperature control controls the average temperature for
more than one channel. If a heater burnout occurs during gradient
temperature control and the temperature of that channel
decreases, physical damage may occasionally occur because the
temperature of the other channels will incr ea se. When usi ng
gradient temperature control, implement suitable safety measures
for the entire system using heater burnout alarms or temperature
information for individual channels.
ix
Precautions for Safe Use
Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects on
the performance and functions of the product. Not doing so may occasionally result in unexpected events.
1) The product is designed for indoor use only. Do not use the product outdoors or in any of the following
locations.
• 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 or ammonia gas)
• Places subject to intense temperature change
• Places subject to icing or condensation
• Places subject to vibration or strong shocks
2) Use and store the product within the rated ambient temperature and humidity ranges.
Mounting two or m ore Temperature Co ntrollers side by side, or mountin g Temperature Co ntrollers above
each other may cause heat to build up inside the Temperature Controllers, which will shorten th eir se rvice
life. If the Temperature Controllers are mounted above each other or side by side, use forced cooling by
fans or other means of air ventilation to cool down the Temperature Controllers.
3) To allow heat to esc ape, do not block the area around th e product. Do not block the ventilation ho les on
the product.
4) Be sure to wire properly with correct polarity of terminals.
5) Use specified size (M3, width 5.8 mm or less) crimped terminal s for wiri ng. Use a gage of AWG22 to
AWG14 (equal to cross-sectional area of 0.326 to 2.081 mm
AWG28 to AWG16 (equal to cross-sectional a r ea o f 0.0 81 to 1.309 mm
length is 6 to 8 mm.) Up to two wires of same size and type, or two crimped terminals can be inserted into
a single terminal .
6) Do not wire terminals that do not have an identified use.
7) To reduce inductive noise, keep the wiring for the product's terminal block away from power cables
carrying 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 the product within the rated load and power supply.
9) Make sure that the rated voltage i s attained within two se co nds o f turning ON t he power us ing 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 product 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) The switch or circuit breaker must be within easy reach of the operator, and must be marked as a
disconnecting means for this unit.
12) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.
13) Design the system (e.g., the control panel ) allowing leeway for the delay required before produ ct outputs
are valid after turning ON power to the product.
14) Never touch the electronic components, connect ors, or patter ns on prod uct boards wit h your bare hands.

15) Use a switch, relay, or other device with contacts to turn OFF the power supply quickly. Gradually lowering
the voltage of the power supply may result in incorrect outputs or memory errors.
16) Do not touch the elec tronic components with your hands or sub ject them to shock when removing the
terminal block.
17) Connect only the specified number of products in only a specified configuration.
18) Mount the product to a DIN Rail mounted vertically to the ground.
19) Always turn OFF the power supply before wiring the product, replacing the product, or changing the
product configuration.
20) Attach the enclosed cover seal to the connector opening on the left end Unit during installation.
21) Do not use port B on the End Unit when using port C on the HFU.
xi
Precautions for Correct Use
● Installation
1) Do not connect an End Unit directly to an HFU.
2) Always connect an End Unit to the right side of the Basic Units.
3) Always connect the HFU to the left side of the Basic Units.
4) The EJ1 cannot be used linked to a CJ-series PLC.
5) Use the EJ1G-@@ for gradie nt temperature control. Use the EJ1N-@@ for any other type of temperature
control.
6) When removing the terminal block to replace the Unit, be sure to confirm that the new Unit is the same as
the Unit that is being replaced.
● Service Life
1) Use the product within the following temperature and humidity ranges.
Temperature:
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 ambient temperature does not exceed 55
2) The service life of electronic d evices like the Tem perature Controller is deter mined by the ser vice life of
internal electronic components. Component service life is affected by the ambient temperature: the higher
the temperature, the shor ter 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) Mounting two or more Temperature Co ntrollers sid e by side, or moun ting Temperature Controllers a bove
each other may cause heat to build up inside the Temperature Controllers, which will shorten th eir se rvice
life. If the Temperature Controllers are mounted above each other or side by side, use forced cooling by
fans or other means of air ventilation to cool down the Temperature Controllers. However, be sure not to
cool only the terminals. Doing so will result in measurement errors.
−10 to 55°C (with no icing or condensation)
°C.
● Ensuring 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 pl ati num re si st ance thermometer, be sure to use wires
that have low resistance and keep the resistance of the three lead wires the same.
3) Mount the Temperature Controller so that it is horizontally level.
4) If the measurement accuracy is low, check to see if input shift has been set correctly.
● Precautions for Operation
1) It takes a certain amount of time for the outputs to turn ON from after the power supply is tu rned ON. Due
consideration must be given to this time when designing control panels, etc.
2) It takes 30 minutes from the time the product is turned ON until the correct temperature is indicated.
Always turn ON the power supply at least 30 minutes before starting temperature control.
3) Avoid using the Temperat ure Con tr oll er near a radio, television set, or other wireless device. Its use would
result in reception disturbance.

1-2-2 What Is Gradient Temperature Control?
Gradient temperature control is a control method that achieves a uniform temperature or preset temperature profile over a 2D surface. An example application would be multi-point control of surface temperature using multiple
heaters. The gradient temperature control algorithm directly controls the average temperature of all point s as well as the temperature difference between
each pair of points. The algorithm also includes methods to eliminate the
interference of each control output on the other control points.
Suppresses interference of
Gradient T emper ature Control
control outputs on other points.
Controls average
temperature.
When temperature inputs are received, the average temperature of all poi nts
and the temperature differences be tween each pair of points are ca lculated.
PID control is performed for the present value (PV) of eac h of these control
points.
In addition, PID o utput values are distributed to prevent them from affecting
PID control performance at other poin ts, thus eliminating interference. This
means that the inte rference of heaters on other control points is reduced to
enable uniform in-plane temperature control.
1-2-3 Main Unit Functions
Basic Units (TC4 and
TC2)
• Basic Units are used as the control I/O devices. (The HFU performs control processing.)
• There are two models of Basic Unit: The TC4 with four I/O channels an d
the TC2 with two I/O channels.
• Universal input supports a ther m ocoupl e, platinum resis tance thermometer, or analog input.
• The type of input can be set separately for each channel.
• Control outputs are pulse voltage outputs.
Controls temperature
differences.

I/O Configuration and Main Functions Section 1-2
• Terminal blocks can be detached and attached. Both screw terminals and
screw-less clamp terminals are available.
• Connect a current transformer (CT) to use t he heater burno ut and heater
overcurre nt alarms (TC2 Units only).
• Up to eight G3ZA Multi-cha nnel Power Controlle rs can be connected to
one Basic Unit.
Advanced Unit (HFU) • The HFU performs gradient temperat ure control or 2-PID con trol (set for
each group).
• Gradient temperature control can be performed for from 2 to 32 channels.
(2-PID control can also be set by group for from 2 to 32 channels.)
• Two-channel gradient temperature control can be performed for up to 16
groups (when TC4 and TC2 U nits are used) or 3 2-channel gradient temperature control can be performed for up to 2 groups (when TC4 Units are
used).
• Up to sixteen Basic Units can be connected to one HFU.
• Data can be exchanged between the EJ1G and PLCs using programless
communications.
• Up to 300 data items can be re ad from a PLC to the EJ 1G and u p to 300
data items can be written from the EJ1G to a PLC.
• OMRON CS/CJ-series PLCs and Mitsubishi Q/QnAS-series PLCs can be
connected.
End Unit (EDU) • The End Unit supplies power to connected Basic Units and HFUs.
• An End Unit is always required when using the EJ1G.
• A total of up to 16 HFUs and Basic Units can be conn ected to one End
Unit.
• Port A is split into both a connector and a terminal block. The connector is
used with the Suppor t Software and the ter minal block is used for EJ1G
distributed placement. (Port B is also used for distributed placement.)
• When using port A, be sure to consider the write life of the EEPROM.
