Advanced Digital Temperature Controller E5CN-H 9

External Connections

• A voltage output (control output, for driving SSR) is not electrically insulated from the internal circuits. When using a grounding thermocouple,
do not connect any of the control output terminals to ground. If the control output terminals are connected to ground, errors will occur in the
measured temperature values as a result of leakage current.

Controllers

Note: Wire all voltage input terminals correctly. The Controller may fail if voltage input terminals are wired incorrectly.

• To mount the Controller so that it is
waterproof, insert the waterproof packing
onto the Controller.

• When two or more Controllers are mounted,
make sure that the surrounding
temperature does not exceed the allowable
operating temperature specified in the
specifications.

Waterproof Packing

Y92S-29 (for DIN 48 × 48)

Order the Waterproof Packing separately if it becomes lost or
damaged.
The Waterproof Packing can be used to achieve an IP66 degree of
protection.
(Deterioration, shrinking, or hardening of the waterproof packing may
occur depending on the operating environment. Therefore, periodic
replacement is recommended to ensure the level of waterproofing
specified in IP66. The time for periodic replacement depends on the
operating environment. Be sure to confirm this point at your site.
Consider one year a rough standard. OMRON shall not be liable for
the level of water resistance if the customer does not perform periodic
replacement.)
The Waterproof Packing does not need to be attached if a waterproof
structure is not required.

Note: The E53-COV10

can not be used.

✽1. You can return to the operation level by executing a software reset.
✽2. It is not possible to move to other levels from the calibration level by operating the keys on the front panel.

It can be done only by first turning OFF the power.

✽3. From the manual control level, key operations can be used to move to the operation level only.

Error Displays (Troubleshooting)

When an error occurs, the No.1 display shows the error code. Take necessary measure according to the error code, referring the table below.

Note: If the input value exceeds the display limit (-19999 to 32400), though it is within the control range, will be displayed under -19999

and above 32400. Under these conditions, control output and alarm output will operate normally.
For details on the control range, refer to the E5CN-H/E5AN-H/E5EN-H Digital Controllers User's Manual Advanced Type (Cat. No. H157).

✽ These errors are displayed only when the PV/SP is displayed. Errors are not displayed for other displays.

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 having

the current and voltage of the secondary output restricted to
specific levels.

✽3. The tightening torque for E5CN-U is 0.5 N·m.

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 mm

2

).
(The stripping length is 5 to 6 mm.) Up to two wires of the same
size and type 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.

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 cable for the Support Software
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. ✽1
d) Caution: To reduce the risk of fire or electric shock, do

not interconnect the outputs of different Class 2

circuits. ✽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 to between 0.74 and

0.90 N·m. ✽3 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.

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
the cable connector for the Support Software. Failure to
do so may occasionally result in minor electric shock, fire,
or damage to equipment.

Do not allow dust and dirt to collect between the pins in
the connector on the Conversion Cable. Failure to do so
may occasionally result in fire.

When inserting the body of the Temperature Controller
into the case, confirm that the hooks on the top and
bottom are securely engaged with the case. If the body of
the Temperature Controller is not inserted properly, faulty
contact in the terminal section or reduced water
resistance may occasionally result in fire or malfunction.

When connecting the Control Output Unit to the socket,
press it in until there is no gap between the Control Output
Unit and the socket. Otherwise contact faults in the
connector pins may occasionally result in fire or
malfunction.

Advanced Digital Temperature Controller E5CN-H 19

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 number of EEPROM write operations is limited. Therefore,
use RAM write mode when frequently overwriting data during
communications or other operations.

18.Always touch a grounded piece of metal before touching the
Temperature Controller to discharge static electricity from your
body.

19.Do not remove the terminal block. Doing so may result in failure or
malfunction.

20.Control outputs (for driving SSR) that are voltage outputs are not
isolated from the internal circuits. When using a grounded
thermocouple, do not connect any of the control output terminals
to ground. (Doing so may result in an unwanted circuit path,
causing error in the measured temperature.)

21.When replacing the body of the Temperature Controller, check the
condition of the terminals. If corroded terminals are used, contact
failure in the terminals may cause the temperature inside the
Temperature Controller to increase, possibly resulting in fire. If the
terminals are corroded, replace the case as well.

22.Use suitable tools when taking the Temperature Controller apart
for disposal. Sharp parts inside the Temperature Controller may
cause injury.

23.Before connecting an Output Unit, confirm the specifications and
thoroughly read relevant information in the datasheet and manual
for the Temperature Controller.

24.Check the orientation of the connectors on the Conversion Cable
before connecting the Conversion Cable. Do not force a
connector if it does not connect smoothly. Using excessive force
may damage the connector.

25.Do not place heavy object on the Conversion Cable, bend the
cable past its natural bending radius, or pull on the cable with
undue force.

26.Do not connect or disconnect the Conversion Cable while
communications are in progress. Product faults or malfunction
may occur.

27.Make sure that the Conversion Cable's metal components are not
touching the external power terminals.

28.Do not touch the connectors on the Conversion Cable with wet
hands. Electrical shock may result.

29.Before using infrared communications, correctly attach the
enclosed Mounting Adapter to the cable for the Support Software.
When connecting the infrared port on the cable to the Support
Software into the Adapter, insert the connector to the specified
line. Communications may not be possible if the connector is not
connected properly.

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: IP66
Rear case: IP20, Terminal section: IP00
(E5CN-U: Front panel: IP50, rear case: IP20, terminals: 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.)

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.

Others

1. The disk that is included with the Conversion Cable is designed for

a computer CD-ROM driver. Never attempt to play the disk in a
general-purpose audio player.

2. Do not connect or disconnect the Conversion Cable connector
repeatedly over a short period of time. The computer may
malfunction.

3. After connecting the Conversion Cable to the computer, check the
COM port number before starting communications. The computer
requires time to recognize the cable connection. This delay does
not indicate failure.

4. Do not connect the Conversion Cable through a USB hub. Doing
so may damage the Conversion Cable.

5. Do not use an extension cable to extend the Conversion Cable
length when connecting to the computer. Doing so may damage
the Conversion Cable.

Mounting the Terminal Cover

E5CN

Make sure that the “UP” mark is facing up, and then attach the E53­COV17 Terminal Cover to the holes on the top and bottom of the
Temperature Controller.

Removing the Temperature Controller from the
Case

The Temperature Controller can be removed from the case to perform
maintenance without removing the terminal leads. This is possible for
only the E5CN, E5AN, and E5EN, and not for the E5CN-U. Check the
specifications of the case and Temperature Controller before
removing the Temperature Controller from the case.

E5CN

1. Insert a flat-blade screwdriver into the two tool insertion holes (one

on the top and one on the bottom) to release the hooks.

2. Insert the flat-blade screwdriver in the gap between the front panel
and rear case, and pull out the front panel slightly. Hold the top and
bottom of the front panel and carefully pull it out toward you,
without applying unnecessary force.

3. When inserting the body of the Temperature Controller into the
case, make sure the PCBs are parallel to each other, make sure
that the sealing rubber is in place, and press the E5CN toward the
rear case into position. While pushing the E5CN into place, push
down on the hooks on the top and bottom surfaces of the rear case
so that the hooks are securely locked in place. Be sure that
electronic components do not come into contact with the case.

Precautions when Wiring

• Separate input leads and power lines in order to prevent external
noise.

• Use wires with a gage of AWG24 (cross-sectional area:

0.205 mm

2

) to AWG14 (cross-sectional area: 2.081 mm2) twisted-

pair cable (stripping length: 5 to 6 mm).

• Use crimp terminals when wiring the terminals.

• Tighten the terminal screws to a torque of 0.74 to 0.90 N·m,

however the terminal screws on the E5CN-U must be tightened to
a torque of 0.5 N·m.

• Use the following types of crimp terminals for M3.5 screws.

• Do not remove the terminal block. Doing so will result in

malfunction or failure.
