Safety Precautions
Indicates a potentially hazardous situation which, if not avoided, is
CAUTION likely to result in minor or moderate injury or property damage. Read
this manual carefully before using the product.
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.
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. 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.
Suitability for Use
OMRON shall not be responsible for conformity with any standards, codes, or regulations that apply to the combination

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 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 rated temperature of over 70°C and a
gauge of AWG24 to AWG14 (equal to a cross-sectional area of 0.205 to 2.081 mm
length is 5 to 6 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 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 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) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.
(13) Design system (control panel, etc) considering the 2 second of delay that the controller's output to be
set after power ON.
(14) The output may turn OFF when shifting to certain levels. Take this into consideration when performing
control.
(15) The number of non-volatile memory write operations is limited.

The control output and the alarm output will turn OFF when an error occurs.
(For s.err, the alarm output will be processed for a high temperature error.)
If the input value exceeds the display limit (-1999 to 9999) but it is still within the control range,
[[[[ will be displayed for values under -1999.
Under these conditions, the control output and alarm output will operate normally.
*1: This error is displayed only when the process value and set point are displayed.
*2: If the display does not change, the Controller needs to be repaired.
If operation returns to normal, then noise may have caused the problem. Check for noise.
*3: On the E5EWL, e111 will be displayed on display No. 1 and sum will be displayed on display No. 2.

Recommended panel thickness is 1 to 5 mm.
The voltage output (control output) is not electrically isolated from the internal
wiring. One or the other of the control output terminals must therefore be left
ungrounded when using a grounded thermocouple thermometer. (If both are
grounded, measurements will be unreliable due to sneak current.)
