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 - 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) When using more than one shutoff switch, always turn OFF all

the shutoff switches to ensure that no power is being supplied

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.

xi

CAUTION

Tighten the terminal screws to between 0.74 and 0.90 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 Digital Controller may occasionally make
control operations impossible or prevent alarm outputs, resulting
in property damage. To maintain safety in the event of malfunction
of the Digital Controller, take appropriate safety measures, such
as installing a monitoring device on a separate line.

When inserting the body of the Digital Controller into the case,
confirm that the hooks on the top and bottom are securely
engaged with the case. If the body of the Digital 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.

xii

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. Do
not handle the Controller in ways that exceed product specifications.

1) The product is designed for indoor use only. Do not use or store the product in any of 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 Digital Controller within the rated ambient temperature and humidity.
Gang-mounting two or more Digital Controllers, or mounting Digital Controllers above each other may

cause heat to build up inside the Digital 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 Digital 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 specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. To connect bare wires, use
stranded or solid copper wires with a gage of AWG24 to AWG14 (equal to cross-sectional areas of 0.205

to 2.081 mm

2

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

terminals can be inserted into a single terminal.

6) Do not wire the terminals which are not used.

7) To avoid inductive noise, keep the wiring for the Digital Controller's terminal block away from power cables
carry high voltages or large currents. Also, do not wire power lines together with or parallel to Digital
Controller 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 Digital controller.
Allow as much space as possible between the Digital Controller 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 Digital 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) A switch or circuit breaker should be provided close to this unit. The switch or circuit breaker should be
within easy reach of the operator, and must be marked as a disconnecting means for this unit.

12) 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.

13) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.

14) Design system considering the 2 second of delay that the controller’s output to be set after power ON.

15) The output may turn OFF when shifting to certain levels. Take this into consideration when performing
control.

Precautions for Safe Use

xiii

16) The number of nonvolatile memory write operations is limited. Therefore, use RAM write mode when
frequently overwriting data during communications or other operations.

17) Always touch a grounded piece of metal before touching the Digital Controller to discharge static
electricity from your body.

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

19) Control outputs 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.)

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

21) Use suitable tools when taking the Digital Controller apart for disposal. Sharp parts inside the Digital
Controller may cause injury.

22) Check the specifications of the Control Output Unit and assemble it correctly.

23) When mounting the Control Output Unit, read and follow all relevant information in the product catalogs
and manuals.

24) Do not continue to use the Controller if the front surface peels or becomes cracked.

● Service Life

Use the Digital Controller within the following temperature and humidity ranges:
Temperature: −10 to 55°C (with no icing or condensation), Humidity: 25% to 85%

If the Controller is installed inside a control board, the ambient temperature must be kept to under
55°C, including the temperature around the Controller.

The service life of electronic devices like Digital 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 Digital Controller.

When two or more Digital 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 Digital 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 Digital Controllers. When providing forced cooling, however, be careful not to cool
down the terminals sections alone to avoid measurement errors.

● Ambient Noise

To avoid inductive noise, keep the wiring for the Digital Controller's terminal block wiring away from
power cables carrying high voltages or large currents. Also, do not wire power lines together with or
parallel to Digital Controller 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 Digital Controller.
Allow as much space as possible between the Digital Controller and devices that generate powerful
high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.

● Ensuring Measurement Accuracy

When extending or connecting the thermocouple lead wire, be sure to use compensating wires that
match the thermocouple types.

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.

Mount the Digital Controller so that it is horizontally level.

xiv

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

To install the Controller so that it is waterproof, insert the Waterproof Packing. The degree of protection
when the Waterproof Packing is used is IP66. To maintain an IP66 degree of protection, the Water­proof Packing should be periodically replaced because it may deteriorate, shrink, or harden depending
on the operating environment. The replacement period will vary with the operating environment. Check
the required period in the actual application. Use one year as a guideline. If the Waterproof Packing is
not periodically replaced, waterproof performance may not be maintained. If a waterproof structure is
not required, then the Waterproof Packing does not need to be installed.

xv

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 Digital Controllers into a control panel or
similar device.

2) Make sure that the Digital 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.

3) Avoid using the Controller in places near a radio, television set, or wireless installing. The Controller may
cause radio disturbance for these devices.

Be sure to thoroughly read and understand the manual provided with the product, and check the fol­lowing points.

1-1-3 Using the Keys

This section describes the basic functions of the front panel keys.

PF (Function or Run/
Reset) Key (E5AN-HT and
E5EN-HT Only)

This is a programmable function key. When it is pressed for at least 1 second,
the function set in the PF Setting parameter will operate.

Example for When the PF Setting Parameter Is Set to R-R (Default: R-R):
With this setting, the PF Key operates as a Reverse Run/reset Key to switch

between run status and reset status.
The status changes from reset to run status when the key is pressed for at

least one second and changes from run to reset status when the key is
pressed for at least two seconds.

O Key Press this key to move between setting levels. The level is selected in the fol-

lowing order: operation level, program setting level, adjustment level, PID set­ting level, and then operation level. From initial setting level you can go to and
from communications setting level.

M Key Press this key to change parameters within a setting level.

The parameters can be reversed by holding down the key (moving one per
second in reverse order).

U Key Each press of this key increments the value displayed on the No. 2 display or

advances the setting. Holding the key down speeds up the incrementation.

D Key Each press of this key decrements values displayed on the No. 2 display or

reverses the setting. Holding the key down speeds up the incrementation.

O + M Keys Press these keys to change to the protect level. For details on operations

involving holding these keys down simultaneously, refer to 1-3 Setting Level

Configuration and Key Operations. For details on the protect level, refer to
SECTION 5 Parameters.

O + U Keys
O + D Keys

To restrict set value changes (in order to prevent accidental or incorrect oper­ations), these key operations require simultaneously pressing the O key
along with U or D key. This applies only to the parameter for the password to
move to protect level. (Refer to page 182.)

M + U Keys (E5CN-HT
Only)

The function that is set for the PF Setting parameter will operate when the
Mode Key and Up Key are pressed at the same time for at least one second.
They perform the same function as the PF Key. If you are using the E5CN-HT,
use the M+U Keys whenever the manual says to use the PF Key.
