Precautions for Safe Use

E5@C Digital Temperature Controllers User’s Manual (H174)

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. Do not handle the Digital Controller in ways that exceed the ratings.

• The product is designed for indoor use only. Do not use or store the product outdoors or 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.

• Use and store the Digital Controller within the rated ambient temperature and humidity.
Gang-mounting two or more Digital Controllers, or mounting Digit al Controllers abo v e each oth er ma y
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.

• To allow heat to escape, do not block the area around the Digital Controller. Do not block the
ventilation holes on the Digital Controller.

• Be sure to wire properly with correct polarity of terminals.

• Use the specified size of crimped terminals (M3, width of 5.8 mm or less) to wire the E5CC, E5EC,

E5AC, o r E5DC . To connect bare wires to the t erminal bloc k of the E5CC , E5EC, E5AC , or E5DC , use
copper braided or solid wires with a gage of AWG24 to AWG18 (equal to a cross-sectional area of

0.205 to 0.8231 mm

2

). (The stripping length is 6 to 8 mm.) Up to tw o wires of the same siz e an d type,
or two crimped terminals can be inserted into a single terminal.
Use the specified size of crimped terminals (M3.5, width of 7.2 mm or less) to wire the E5CC-U. To
connect bare wires to the ter minal block of the E5CC-U, 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

2

). (The stripping
length is 5 to 6 mm.) Up to two wires of the same size and type, or two crimped terminals, can be
inserted into a single terminal.

• Do not wire the terminals that are not used.

• To avoid inductive noise, keep the wiring for the Digital Controller's terminal block away from power

cables that 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 v oltage or current, and attach th e 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.

• Use the Digital Controller within the rated load and power supply.

• Make sure that the rated voltage is attained within 2 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 outp ut malf unct ion s
may occur.

• 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.

Precautions for Safe Use

8

E5@C Digital Temperature Controllers User’s Manual (H174)

• When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or before
supplying power to the Digital Controller. If pow er is turned ON for the Digital Controller bef ore turning
ON power for the load, self-tuning will not be performed properly and optimum control will not be
achieved.

• A switch or circuit breaker must be provided close to Digital Controller. The switch or circuit breaker
must be within easy reach of the operator, and must be marked as a disconnecting means for Digital
Controller.

• Wipe off any dirt from the Digital Controller with a soft dry cloth. Ne ver use thinners, benzine, al cohol,
or any cleaners that contain these or other organic solvents. Deformation or discoloration may occur.

• Design the system (e.g., control panel) considering the 2 seconds of delay in setting the Digital
Controller’s output after the power supply is turned ON.

• The output will turn OFF when you move to the Initial Setting Level. Take this into consideration when
performing control.

• The number of non-volatile memory write operations is limited. There f ore , use RAM write mode when
frequently overwriting data, e.g., through communications.

• Use suitable tools when taking the Digital Controller apart for disposal. Sharp par ts inside the Dig ital
Controller may cause injury.

• For compliance with Llo yd’s standards, the E5CC, E5CC-U, E5EC , and E5A C must b e installed under
the conditions that are specified in Shipping Standards.

• Do not exceed the communications distance that is given in the specifications and use the specified
communications cable.

• Do not turn the power supply to the Digital Controller ON or OFF while the USB-Serial Conversion
Cable is connected. The Digital Controller may malfunction.

• Do not bend the communications cables past their natural bending radius. Do not pull on the
communications cables.

• For the E5DC, when you attach the Main Unit to the Terminal Unit, make sure that the hooks on the
Main Unit are securely inserted into the Terminal Unit.

• For the E5CC-U, when you attach the Main Unit to the socket, make sure that the hooks on the
socket are securely inserted into the Main Unit.

• Install the DIN Track vertically to the ground.

• For the E5DC, always turn OFF the power supply before connecting the Main Unit to or disconnecting

the Main Unit from the Terminal Unit, and never touch nor apply shock to the terminals or electronic
components. When connecting or disconnecting the Main Unit, do not allow the electronic
components to touch the case.

Installation Precautions

E5@C Digital Temperature Controllers User’s Manual (H174)

Installation Precautions

z 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 Digital 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.

z 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.
If the measurement accuracy is low, check to see if input shift has been set correctly.

z Resistance to Water (E5CC/E5EC/E5AC Only)

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: I P66
Rear case: IP20, Terminal section: IP00
When waterproofing is required, insert the Waterproof Packing on the backside of the front panel.
Keep the Port Cover on the front-panel Setup Tool port of the E5EC/E5AC securely closed. The
degree of protection when the Waterproof Packing is used is IP66. To maintain an IP66 degree of
protection, the Waterproof Packing and the Port Cover for the front-panel Setup Tool port must be
periodically replaced because they 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 3 years or sooner as a guideline. If the Waterproof Packing and
Port Cover are 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.

Precautions for Operation

10

E5@C Digital Temperature Controllers User’s Manual (H174)

Precautions for Operation

• When using self-tuning, turn ON power for the load (e.g., heater) at the same time as or before

supplying power to the Digital Controller. If pow er is turned ON for the Digital Controller bef ore turning
ON power for the load, self-tuning will not be performed properly and optimum control will not be
achieved. When starting operation after the Digital 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
Digital Controller OFF and ON again, switching fr om STOP Mode to RUN Mode can also be used.)

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

Shipping Standards

The E5CC, E5CC-U, E5EC, and E5AC comply with Lloyd’s standards. When applying the standards,
the following installation requirements must be met in the application.

Application Conditions

z Installation Location

The E5CC, E5CC-U, E5EC, and E5AC are applicable to installation category ENV1 or ENV2 of Lloyd’s

Input sampling cycle: 50 ms
Control period: 0.1 s and 0.2 s have been added.
Integral/differential time unit: Setting in increments of 0.1 s has been added.

• Number of event inputs: Increased from 2 to 4 f or the E5CC a nd from 4 to 6 for the E5EC/E5AC .
The E5DC has only 1 event input.

• Number of auxiliary outputs: Increased from 2 to 3 for the E5CC and from 3 to 4 for the E5EC/E5AC .
The E5DC and E5CC-U have 2 auxiliary outputs.

• Remote SP inputs: A remote SP input that treats the external analog signal at the set point
(SP) has been added.

Universal input: The input sensor can be selected freely from the following: Thermocouple, resis-

tance thermometer, ES1B Infrared Temperature Sensor, current, and voltage.

1-1-1 Appearance

• A stylish design

that gives a new
look to control
panels.

• Large display
characters and
white backlight for
better visibility.

• A compact size to
help downsize
control panels.

• Much faster
sampling and
greater
expandability than
expected in this
class of Controller.

1-1-3 Main Functions

Digit shift: When setting the SP or other parameter s, y ou can use a Shi ft Key (assigned to the PF Key)

to shift the digit that is being set to aid changing the set values.

This port allows you to change or set parameters from the Setup Tool even when the Controller is
installed in a panel.

For details on particular functions and how to use them, refer to Section 3 Part Names and Basic Proce-
dures and following sections.

z Input Sensor Types

You can connect the following sensors and signals to the universal input.

z Control Outputs

• A control output can be a relay output, voltage output (for driving SSR), or linear current output,

depending on the model.

z Adjusting PID Constants

• You can easily set the optimum PID constants by performing AT (auto-tuning) with the limit cycle

method or by performing ST (self-tuning) with the step response method.

• You can also add RT (robust tuning) to give priority to controlling stability.

z Alarms

Standard Alarms

• You can output an alarm when the deviation, process value, set point, or manipulated value

reaches a specified value.

• You can also output alarms for the PV rate of change and for loop burnouts.

• If necessary, a more comprehensive alarm function can be achieved by setting a standby

sequence, alarm hysteresis, auxiliary output close in alarm/open in alar m, alarm latch, alar m ON
delay, and alarm OFF delay.

HB and HS Alarms

• With models with the optional HB and HS alarms, you can detect heater burnout and heater short

alarms based on CT inputs.

Integrated Alarm

• You can output an integrated alarm if a standard alarm, HB alarm, or HS alarm turns ON.

E5@C Digital Temperature Controllers User’s Manual (H174)

z Event Inputs

• With any model that supports event inputs, you can use external contact or transistor inputs to

achieve any of the following functions: Switching set points (Multi-SP No. Switch, 8 points max.),
switching RUN/STOP, switching between automatic and manual operation, starting/resetting the
program, inverting direct/reverse operation, switching the SP mode100% AT execute/cancel, 40%
AT execute/cancel, setting change enable/disable, communications write enable/disable, and
canceling the alarm latch.

z Communications Functions

With any E5@C model that supports communications, you can use CompoWay/F, Modbus-RTU,

*1

programless, and comp onent communications.

*1 Modbus is a registered trademark of Schneider Electric.
*2 The E5CC-U does not support communications.

z Transfer Output

With any model that provides a transfer output, you can output the set point, process value,
manipulated variable, or other values as a 4 to 20-mA or 1 to 5-V transfer output.

* The E5CC-U and E5DC do not have a transfer output.

z Remote SP Input

With any model that provides a remote SP input, you can set the set point with an analog input.

* The E5CC-U and E5DC do not have a remote SP input.
