●Warning Symbols
CAUTION
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.
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.
c) Signal inputs are SELV, limited energy.
d) Caution: To reduce the risk of fire or electric shock, do not interconnect the outputs of different Class 2 circuits.
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 1.13 and 1.36 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 Temperature 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 Temperature Controller,
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.
Suitability for Use
OMRON shall not be responsible for conformity with any standards, codes, or regulations that
apply to the combination of the products in the customer's application or use of the product.
Take all necessary steps to determine the suitability of the product for the systems, machines,
and equipment with which it will be used.
Know and observe all prohibitions of use applicable to this product.
NEVER USE THE PRODUCTS FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE
OR PROPERTY WITHOUT ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN
DESIGNED TO ADDRESS THE RISKS, AND THAT THE OMRON PRODUCT IS PROPERLY
RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE OVERALL EQUIPMENT
OR SYSTEM.

Manual".
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 and ammonia gas).
• Places subject to intense temperature change.
• Places subject to icing and condensation.
• Places subject to vibration and large shocks.
(2) Use/store within the rated temperature and humidity ranges.
Provide forced-cooling if required.
(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 to the
terminal block, use copper braided or solid wires with a gage of AWG24 to AWG14 (equal to a cross-
sectional area of 0.205 to 2.081 mm
type, or two crimped terminals can be inserted into a single terminal.
(6) Do not wire the terminals which are not used.
(7) Allow as much space as possible between the controller and devices that generate a powerful high-frequency
or surge.
Separate the high-voltage or large-current power lines from other lines, and avoid parallel or common wiring
with the power lines when you are wiring to the terminals.
(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 the load and the unit ON simultaneously, or turn the load ON before you turn
the controller ON.
(12) 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.
(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 system (control panel, etc) considering the 2 second of delay that the controller'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) The product's Setup Tool port and communications terminals are internally connected in models with
communications functions. Stop transmission from communications terminals before using the Setup Tool port.
(19) Refer to the instruction sheet for installing Option unit (E53-AKB/E53-EN01/E53-EN03).

Waterproofing is impossi-
ble with side-by-side in-
stallation. When water-
proofing is required, fit
watertight packing on the
backside of front panel.
• Insert the main unit through the mounting hole in the panel (1-8 mm
thickness). Insert the mounting brackets (supplied) into the fixing
slots located on the top and bottom of the rear case.
• Alternately tighten the top and bottom screws on the mounting fixtures
applying equal pressure a little at a time until the rachet rotates freely.
• When more than one machine is installed, make sure that the ambi-
ent temperature does not exceed the specified limit.

• Since the voltage output (control output 1) is not electrically insulated from the internal wiring, one or other of the control output
terminals must be left unearthed when using an earthed thermocouple thermometer. (Connection makes measurements unreliable
due to sneak currents.) Basic insulation is provided between the voltage outputs (control output 2) and internal circuits.
• The last character of the lot number "R" indicates that reinforced insulation is provided between input power supply, relay outputs,
and between other terminals.

purposes.

Only the value set to the "ins: temperature input shift" parameter is
applied to the entire temperature input range. When the process value is
200 °C, the process value is treated as 201.2 °C after input shift if the
input shift value is set to 1.2 °C.
The process value is treated as 198.8 °C after input shift if the input shift
value is set to –1.2 °C.

• °C / °F : temperature unit
The temperature unit is displayed
when the displayed value is a
temperature.
When this parameter is set to "°C",
"C" is displayed, and when set to
"°F", "F" is displayed.
