Thank you for purchasing the OMRON E5CS-U
Temperature Controller. This manual describes the
functions, performance, and application methods needed
for optimum use of the product.
Please observe the following items when using the
product.
• This product is designed for use by qualified personnel
with a knowledge of electrical systems.
• Before using the product, thoroughly read and
understand this manual to ensure correct use.
• Keep this manual in a safe location so that it is available
for reference whenever required.
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 0.50 N·m. Loose screws may occasionally result in fire.
Unexpected operation may result in equipment damage or accidents if the settings are not appropriate for the controlled
system. Set the Temperature Controller as follows:
· Set the parameters of the Temperature Controller so that they are appropriate for the controlled system.
·
Turn the power supply to the Temperature Controller OFF before changing any switch setting.
Switch settings are read only when the power supply is turned ON.
·
Make sure that the INIT switch in the control mode selector switches is turned OFF before operating the Temperature
Controller.
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 Temperature Controller, take appropriate
safety measures, such as installing a monitoring device on a separate line.
Indicates a potentially hazardous situation which, if
not avoided, is likely to result in minor or moderate
injury or property damage. Read this manual
carefully before using the product.
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) 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 AWG18 (equal to a cross-sectional area of 0.205
to 0.832 mm2). (The stripping 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.
5) Be sure to wire properly with correct polarity of terminals.
Do not wire any of the I/O terminals incorrectly.
6) Do not wire the terminals which are not used.
7)
The voltage output (control output) is not electrically isolated from the internal circuits. When using a grounded temperature sensor,
do not connect any of the control output terminals to ground. Otherwise unwanted current paths will cause measurement errors.
8)
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.
9) Use this product within the rated load and power supply.
10) 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.
11) When using PID operation (self-tuning), turn ON the power supply to the load at the same time or before turning the
power supply to the Temperature Controller ON.
12) Design system (control panel, etc) considering the 2 second of delay that the controller’s output to be set after
power ON.
13) 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.
14) 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.
15)
Be sure that the platinum resistance thermometer type and the input type set on the Temperature Controller are the same.
16) When extending the thermocouple lead wires, always use compensating conductors suitable for the type of
thermocouple. Do not extend the lead wires on a platinum resistance thermometer. Use only low-resistance wire
(5 Ωmax. per line) for lead wires and make sure that the resistance is the same for all three wires.
17)
Static electricity can damage internal components. Always touch grounded metal to discharge any static electricity before
handling the Temperature Controller. When drawing out the controller from the case, do not touch the electronic components
or patterns on the board with your hand. Hold the Temperature Controller by the edge of the front panel when handling it.
18) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.
19) Use tools when separating parts for disposal.

· Insert the controller through the hole in the panel. Push the mounting
bracket on from the rear and fasten temporarily, removing any gap
between the controller, panel and mounting bracket. Finally, secure
two fixing screws alternately keeping the torque to between 0.29 to
0.39 N·m.
Refer to the dimension diagram for the mounting status.
· When mounting more than one Temperature Controller, be sure that
the heat generated by the Temperature Controllers does not cause
the ambient temperature to exceed the specified value.
· Close side-by-side mounting is possible in one direction only, either
When mounting plural units in vertical arrangement, leave space of
approx. 20 mm above and below the mounting socket.
