b) More than one disconnect switch may be required to deenergize the equipment before servicing the product.
c) Signal inputs are SELV, limited energy.*1
d) Caution: To reduce the risk of fire or electric shock, do not interconnect the outputs of different Class 2circuits.*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.
*1
*2
A SELV circuit is one separated from the power supply with double insulation or reinforced insulation, that
does not exceed 30 V r.m.s. and 42.4 V peak or 60 VDC.
A class 2 power supply is one tested and certified by UL as having the current and voltage of the
secondary output restricted to specific levels.
ix
CAUTION
Tighten the terminal screws to between 0.74 and 0.9 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.
WARNING: To reduce the risk of electric shock or fire, install in a
Pollution Degree 2 environment (a controlled environment
relatively free of contaminants).
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.

Do not use this product in 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 Temperature Controller within the rated ambient temperature and humidity.
Gang-mounting two or more temperature controllers, or mounting temperature controllers above each
other may cause heat to build up inside the temperature 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
Temperature Controllers.
To allow heat to escape, do not block the area around the product. Do not block the ventilation holes on
the product.
Be sure to wire properly with correct polarity of terminals.
Use specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. Use wires with a gage of
AWG24 to AWG14 (equal to cross-sectional areas of 0.205 to 2.081 mm2). (The stripping length is 5 to
6 mm.)
Do not wire the terminals which are not used.
To avoid inductive noise, keep the wiring for the Digital Temperature 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 Temperature 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 temperature controller.
Allow as much space as possible between the Digital Temperature Controller and devices that generate
powerful high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.
Use this product within the rated load and power supply.
Make sure that the rated voltage is attained within two seconds of turning the power ON.
Make sure the controller has 30 minutes or more for warm up.
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 Temperature Controller. If power is turned ON for the Digital Temperature
Controller before 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 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.
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.
Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.
Design system (control panel, etc) considering the 2 second of delay that the controller’s output to be set
after power ON.
The output may turn OFF when shifting to certain levels. Take this into consideration when performing
control.
Refer to the instruction sheet for information on installing Option unit.

● Service Life
Use the Temperature 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 Temperature 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 Temperature Controller.
When two or more Temperature 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 Temperature
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 Temperature 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 Temperature 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 Temperature 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 Temperature Controller.
Allow as much space as possible between the Digital Temperature 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 Temperature Controller so that it is horizontally level.
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: NEMA4X for indoor use (equivalent to IP66)
Rear case: IP20, Terminal section: IP00
(E5CN-U: Front panel: Equivalent to IP50, rear case: IP20, terminals: IP00)

Precautions for Operation
1)
2)
3)
4)
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 Temperature Controllers in a sequence
circuit.
Allow at least 30 minutes for warming up.
When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or before
supplying power to the Temperature Controller. If power is turned ON for the Temperature Controller
before 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 Temperature 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
Temperature Controller OFF and ON again, switching from STOP mode to RUN mode can also be used.)
Avoid using the Controller in places near a radio, television set, or wireless installing. The Controller may
cause radio disturbance for these devices.

Note: (1) A heater short indicates that the heater remains ON even when the control output from the Temperature Controller is OFF because the SSR has failed or for any other reason.
(2) “EU” stands for Engineering Unit. EU is used as the minimum unit for engineering units such as °C,
m, and g. The size of EU varies according to the input type.
For example, when the input temperature setting range is –200 to +1300°C, 1 EU is 1°C, and when
the input temperature setting range is –20.0 to +500.0°C, 1 EU is 0.1°C.
For analog inputs, the size of EU varies according to the decimal point position of the scaling setting,
and 1 EU becomes the minimum scaling unit.

Main Functions
This section introduces the main E5CN/E5CN-U functions. For details on particular functions and how to use them, refer to SECTION 3 Basic Operation
and following sections.
Input Sensor Types
• The following input sensors can be connected for temperature input:
Thermocouple:
K, J, T, E, L, U, N, R, S, B
Infrared temperature sensor:
ES1B
10 to 70°C, 60 to 120°C, 115 to 165°C,
140 to 260°C
Platinum resistance thermometer:Pt100, JPt100
Analog input:
0 to 50 mV
• Inputs with the following specifications can be connected for analog input.
Current input:4 to 20 mA DC, 0 to 20 mA DC
Voltage input:1 to 5 VDC, 0 to 5 V DC, 0 to 10 V DC
Control Outputs
• A control output can be relay, voltage, or current output, depending on the
model.
• Long-life relay outputs use semiconductors for switching when closing
and opening the circuit, thereby reducing chattering and arcing and
improving durability. If high levels of noise or surge are imposed between
the output terminals, short-circuit faults may occasionally occur. If the output becomes permanently shorted, there is the danger of fire due to overheating of the heater. Design safety into the system, including measures
to prevent excessive temperature rise and spreading of fire. Take countermeasures such as installing a surge absorber. As an additional safety
measure, provide error detection in the control loop. (Use the Loop Burnout Alarm (LBA) and HS alarm that are provided for the E5CN.)

100 to 120 VAC
200 to 240 VAC
Varistor voltage
240 to 270 V
440 to 470 V
Surge resistance
1,000 A min.
• Always connect an AC load to a long-life relay output. The output will not
turn OFF if a DC load is connected.
• With the E5CN-@2@@, alarm output 2 is used as control output 2 when
heating/cooling control is selected. Therefore, use alarm 1 if an alarm is
required while using heating/cooling control.
Alarms
• Alarms can be used with the E5CN-@2@@, E5CN-@1@@@U, or E5CN@2@@@U. Set the alarm classification and alarm value or the alarm's
upper and lower limits.
• If necessary, a more comprehensive alarm function can be achieved by
setting the standby sequence, alarm hysteresis, close in alarm/open in
alarm, and alarm latch parameters.
• When the “input error output” parameter is set to ON, alarm output 1 turns
ON when an input error occurs.
6
I/O Configuration and Main Functions
Section 1-2
Control Adjustment
• Optimum PID constants can be set easily by performing AT (auto-tuning)
or ST (self-tuning).
Event Inputs
• With the E5CN-@@@B, the following functions can be executed using
event inputs: switching set points (multi-SP, 4 pts. max.), switching RUN/
STOP status, switching between automatic and manual operation, and
starting/resetting program.
Heater Burnout and HS
Alarms
• With the E5CN-@@H@, the heater burnout detection function and the HS
alarm function can be used.
Communications
Functions
• With the E5CN-@@@03, communications functions utilizing CompoWay/F
(See note 1.), SYSWAY (See note 2.), or Modbus (See note 3.) can be
used.
Note
(1) CompoWay/F is an integrated general-purpose serial communications
protocol developed by OMRON. It uses commands compliant with the
well-established FINS, together with a consistent frame format on
OMRON Programmable Controllers to facilitate communications between personal computers and components.
(2) SYSWAY communications do not support alarm 3 output.
(3) Modbus is a communications control method conforming to the RTU
Mode of Modicon Inc.'s Modbus Protocol.
External Power Supply for
ES1B
The E5CN-@@@P can be used as the power supply for ES1B Infrared Temperature Sensors.
The external power supply for the ES1B cannot be used on the E5CN-C@@
(Current Output Model).

Setting Level Configuration and Key Operations
Section 1-3
Of these levels, the initial setting level, communications setting level,
advanced function setting level, and calibration level can be used only
when control is stopped. Control outputs are stopped when any of
these four levels is selected.
Protect Level
• To switch to the protect level from either the operation level or the adjustment level, simultaneously hold down the O and M keys for at least 3
seconds. (See note.) This level is for preventing unwanted or accidental
modification of parameters. Protected levels will not be displayed, and so
the parameters in that level cannot be modified.
Note
Operation Level
The key pressing time can be changed in “move to protect level
move” parameter (advanced function level).
• The operation level is displayed when the power is turned ON. You can
move to the protect level, initial setting level, or adjustment level from this
level.
• Normally, select this level during operation. While operation is in progress,
items such as the PV and manipulated variable (MV) can be monitored,
and the set points, alarm values, and alarm upper and lower limits can be
monitored and changed.
Adjustment Level
• To move to the adjustment level, press the O key once (for less than 1 s).
• This level is for entering set values and offset values for control. In addition to AT (auto-tuning), communications write enable/disable switching,
hysteresis settings, multi-SP settings, and input offset parameters, it
includes HBA, HS alarm, and PID constants. From the adjustment level, it
is possible to move to the top parameter of the initial setting level, protect
level, or operation level.
Manual Control Level
• When the O key is pressed for at least 3 seconds from the operation
level's auto/manual switching display, the manual control level will be displayed. (The MANU indicator will light.)
• This is the level for changing the MV in manual mode.
• To return to the operation level, press the O key for at least one second.
Initial Setting Level
• To move to the initial setting level from the operation level or the adjustment level, press the O key for at least 3 seconds. The PV display
flashes after one second. This level is for specifying the input type and
selecting the control method, control period, setting direct/reverse action,
and setting the alarm types. You can move to the advanced function setting level or communications setting level from this level. To return to the
operation level, press the O key for at least one second. To move to the
communications setting level, press the O key for less than one second.
(When moving from the initial setting level to the operation level, all the
indicators will light.)
Note
Advanced Function
Setting Level
Pressing the O key for at least 3 seconds in the operation level's
auto/manual switching display will move to the manual control level,
and not the initial setting level.
• To move to the advanced function setting level, set the “initial setting/communications protect” parameter in the protect level to 0 and then, in the
initial setting level, input the password (−169).
• From the advanced function setting level, it is possible to move to the calibration level or to the initial setting level.
9
Section 1-3
Setting Level Configuration and Key Operations
• This level is for setting the display auto-return time, event input assignments, standby sequence, and alarm hysteresis, and it is the level for
moving to the user calibration.
Communications Setting
Level
• To move to the communications setting level from the initial setting level,
press the O key once (for less than 1 s). When using the communications
function, set the communications conditions in this level. Communicating
with a personal computer (host computer) allows set points to be read
and written, and manipulated variables (MV) to be monitored.
Calibration Level
• To move to the calibration level, input the password (1201) from the
advanced setting level. The calibration level is for offsetting error in the
input circuit.
• You cannot move to other levels from the calibration level by operating the
keys on the front panel. To cancel this level, turn the power OFF then back
ON again.
1-3-1
Selecting Parameters
• Within each level, the parameter is changed in order (or in reverse order)
each time the M key is pressed. (In the calibration level, however, parameters cannot be changed in reverse order.) For details, refer to SECTION
5 Parameters.
Moves in order after M key
is pressed (if key is
released within 1 s).
While the M key is being held
down, the parameter will move
each second in reverse order.

Communications Function
The E5CN is provided with a communications function that enables parameters to be checked and set from a host computer. If the communications function is required, use a model that has that function (E5CN-@@@03). For
details on the communications function, see the separate Communications
Functions User's Manual. Use the following procedure to move to the communications setting level.
1,2,3...
1. Press the O key for at least three seconds to move from the operation level
to the initial setting level.
2. Press the O key for less than one second to move from the initial setting
level to the communications setting level.
3. Select the parameters as shown below by pressing the M key.
4. Press the U or D key to change the parameter setting.

the bottom) and release the hooks.
2. Insert the tool in the gap between the front panel and rear case, and pull
out the front panel slightly. Hold the top and bottom of the front panel and
carefully pull it out toward you, without applying unnecessary force.
3. When inserting the E5CN, check to make sure that the waterproof packing
is in place and push the E5CN toward the rear case until it snaps into position. While pushing the E5CN into place, push down on the hooks on the
top and bottom surfaces of the rear case so that the hooks are securely
locked in place. Be sure that electronic components do not come into contact with the case.

Precautions when Wiring
• Separate input leads and power lines in order to prevent external noise.
• Use AWG24 (cross-sectional area: 0.205 mm2) to AWG14 (cross-sectional area: 2.081 mm2) twisted-pair cable (stripping length: 5 to 6 mm).
• Use crimp terminals when wiring the terminals.
• Tighten the terminal screws to a torque of 0.74 to 0.90 N·m.
• Use the following types of crimp terminals for M3.5 screws.
7.2 mm max.
7.2 mm max.
Note
2-2-3
Do not remove the terminal block. Doing so will result in malfunction or failure.
Wiring
In the connection diagrams, the left side of the terminal numbers represents
the inside of the Controller and the right side represents the outside.
Power supply
• With the E5CN, connect to terminals 9 and 10; with the E5CN-U, connect
to pins 10 and 11. The following table shows the specifications.

• Standard insulation is applied to the power supply I/O sections. If reinforced insulation is required, connect the input and output terminals to a
device without any exposed current-carrying parts or to a device with
standard insulation suitable for the maximum operating voltage of the
power supply I/O section.

• Always connect an AC load to a long-life relay output. The output will not
turn OFF if a DC load is connected.
• A voltage output (control output) is not electrically isolated from the internal circuits. When using a grounding thermocouple, do not connect any of
the control output terminals to the ground. If control output terminals are
connected to the ground, errors will occur in the measured temperature
values as a result of leakage current.
• Control output 2 is for voltage only, and outputs are executed across terminals 11 (+) and 12 (−), or across 14 (+) and 15 (−).
• Control outputs 1 and 2 (voltage outputs) are not isolated.
• Long-life relay outputs use semiconductors for switching when closing
and opening the circuit, thereby reducing chattering and arcing and
improving durability. If high levels of noise or surge are imposed between
the output terminals, short-circuit faults may occasionally occur. If the output becomes permanently shorted, there is the danger of fire due to overheating of the heater. Design safety into the system, including measures
to prevent excessive temperature rise and spreading of fire. Take countermeasures such as installing a surge absorber. As an additional safety
measure, provide error detection in the control loop. (Use the Loop Burnout Alarm (LBA) and HS alarm that are provided for the E5CN.)

Section 2-2
Wiring Terminals
• When the “input error output” parameter is set to ON, alarm output 1 turns
ON when an input error occurs.
• When the HBA or the HS alarm is used with the E5CN-@@H@ or the
E5CN-@@HH@, alarms are output across terminals 7 and 8.
• With the E5CN-@1@@@U, alarm output 1 (ALM1) is output across terminals 7 and 8.
• On the E5CN-@2@@@U, alarm output 1 (ALM1) is output across terminals 7 and 8, and alarm output 2 (ALM2) is output across terminals 7 and
9.
When heating/cooling control is used, alarm output 2 becomes control
output 2.
• For models that have a heater burnout alarm, an OR of alarm output 1
and the HBA/HS alarm is output. If ALM1 is to be used for HBA only, set
the alarm 1 type to 0 and do not use alarm output 1.
• The following diagrams show the internal equalizing circuits for alarm outputs 1 and 2.

The Controller supports four input types: platinum resistance thermometer,
thermocouple, infrared temperature sensor, and analog inputs. Set the input
type that matches the sensor that is used. In the product specifications, there
are models with thermocouple/resistance thermometer inputs (multi-input)
and models with analog input. The settings differ depending on the model.
Check to make sure which model you are using.

Selecting PID Control or ON/OFF Control
Two control methods are supported: 2-PID control and ON/OFF control.
Switching between 2-PID control and ON/OFF control is executed by means
of the “PID ON/OFF” parameter in the initial setting level. When this parameter is set to pid, 2-PID control is selected, and when set to onof, ON/OFF
control, is selected. The default is onof.
2-PID Control
PID control is set by AT (auto-tuning), ST (self-tuning), or manual setting.
For PID control, set the PID constants in the “proportional band” (P), “integral
time” (I), and “derivative time” (D) parameters.
ON/OFF Control
3-5

In ON/OFF control, the control output is turned ON when the process value is
lower than the current set point, and the control output is turned OFF when
the process value is higher than the current set point (reverse operation).

set to 20 seconds or longer for a relay output to preserve the service life
of the relay. After the settings have been made in the initial setup, readjust
the control period, as required, by means such as trial operation.
• Set the control periods in the “control period (heat)” and “control period
(cool)” parameters in the initial setting level. The default is 20 seconds.
• The “control period (cool)” parameter is used only for heating/cooling control.

Reverse operation
For example, when the process value (PV) is lower than the set point (SP)
in a heating control system, the manipulated variable increases according
to the difference between the PV and SP. Accordingly, reverse operation is
used in a heating control system. Direct operation is used in a cooling control system, in which the operation is the opposite of a heating control system.
• Direct/reverse operation is set in the “direct/reverse operation” parameter
in the initial setting level. The default is or-r (reverse operation).

Using ON/OFF Control
3-7
Using ON/OFF Control
In ON/OFF control, the control output turns OFF when the temperature being
controlled reaches the preset set point. When the manipulated variable turns
OFF, the temperature begins to fall and the control turns ON again. This operation is repeated over a certain temperature range. At this time, how much the
temperature must fall before control turns ON again is determined by the
“hysteresis (heating)” parameter. Also, what direction the manipulated variable must be adjusted in response to an increase or decrease in the process
value is determined by the “direct/reverse operation” parameter.
3-7-1
ON/OFF Control
• Switching between 2-PID control and ON/OFF control is performed using
the “PID ON/OFF” parameter in the initial setting level. When this parameter is set to pid, 2-PID control is selected, and when it is set to onof, ON/
OFF control is selected. The default is onof.
Hysteresis
• With ON/OFF control, hysteresis is used to stabilize operation when
switching between ON and OFF. The control output (heating) and control
output (cooling) functions are set in the “hysteresis (heating)” and “hysteresis (cooling)” parameters, respectively.
• In standard control (heating or cooling control), the setting of the “hysteresis (heating)” parameter in the adjustment level is used as the hysteresis
regardless of whether the control type is heating control or cooling control.

• When AT is executed, the optimum PID constants for the set point at that
time are set automatically. A method (called the limit cycle method) for
forcibly changing the manipulated variable and finding the characteristics
of the control object is employed.
• To execute AT, specify on (AT execute), and to cancel AT, specify off (AT
cancel).
• AT cannot be executed when control has stopped or during ON/OFF control.
• The results of AT are reflected in the “proportional band” (P), “integral

ST (Self-tuning)
ST (auto-tuning) is a function that finds PID constants by using step response
tuning (SRT) when Controller operation begins or when the set point is
changed.
st
Once the PID constants have been calculated, ST is not executed when the
next control operation is started as long as the set point remains unchanged.
ST (self-tuning) is enabled when the “ST” parameter is set to ON in the initial
setting level.
When the ST function is in operation, be sure to turn the power supply of the
load connected to the control output ON simultaneously with or before starting
Controller operation.

Startup Conditions
Self-tuning by step response tuning (SRT) is started when the following conditions are met after program execution is started and the set point is changed.
At start of operation
1. The set point at the start of operation
differs from the set point when the previous SRT was executed. (See note 1.)
2. The difference between the temperature at the start of operation and the set
point is greater both of the following:
(Present proportional band × 1.27 +
4°C) and the ST stable range.
3. The temperature at the start of operation is lower than the set point during
reverse operation, and is larger than
the set point during direct operation.
4. There is no reset from input errors.
Note
When set point is changed
1. The new set point differs from the set
point used when the previous SRT was
executed. (See note 1.)
2. The set point change width is greater
both of the following: (Present proportional band × 1.27 + 4°C) and the ST
stable range.
3. During reverse operation, the new set
point is larger than the set point before
the change; and during direct operation, the new set point is smaller than
the set point before the change.
4. The temperature is stable. (See note
2.) (Equilibrium with the output amount
at 0% when the power is turned ON is
also all right.) (See note 3.)
(1) The previous SRT-implemented set point is the set point that was used for
calculating the PID constants for the previous SRT.
(2) In this state, the measurement point is within the ST stable range.
(3) In this state, the change width of the PV every 60 seconds is within the
ST stable range or less.
In the following instances, PID constants are not changed by self-tuning (ST)
for the present set point.

1. When the PID constants have been changed manually with ST set to ON.
2. When auto-tuning (AT) has been executed.

RT (Robust Tuning)
• When AT or ST is executed with RT selected, PID constants are automatically set that make it hard for control performance to degenerate even
when control object characteristics are changed.
rt
• RT can be set in the advanced function setting level when PID control has
been set.
• The RT mode cannot be selected while an analog input is set.
• Selecting the RT mode in the following cases will help to prevent hunting
from occurring.
• When the set temperature is not fixed and is changed in a wide range
• When there are large variations in ambient temperatures due to factors
such as seasonal changes or differences between day and night temperatures
• When there are large variations in ambient wind conditions and air flow
• When heater characteristics change depending on the temperature
• When an actuator with disproportional I/O, such as a phase-controltype power regulator, is used
• When a rapidly heating heater is used
• When the control object or sensor has much loss time
• When hunting occurs in normal mode for any reason
• PID constants are initialized to the factory settings by switching to RT
mode.
• When the RT mode is selected, the derivative time setting unit becomes the second.
RT Features
• Even when hunting occurs for PID constants when AT or ST is executed
in normal mode, it is less likely to occur when AT or ST is executed in RT
mode.

3-10-1 HBA and HS Alarm Operations
• Heater burnout detection is executed by measuring heater current while
the control output for heating is ON, and HS detection is executed by
measuring heater current while it is OFF. For details, refer to the following
table.

Note
(1) In the above diagram, power is considered to be ON (normal) if the heater
current is greater than the heater burnout detection current during the Ton
interval. If the heater is burned out, the measured current decreases and
falls below the heater burnout detection value. The output is then activated as the heater burnout alarm.
(2) In the above diagram, power is considered to be OFF (normal) if the leakage current is less than the HS alarm current during the Toff interval. If
the SSR output is short-circuited, the measured current increases beyond the HS alarm value. The output is then activated as the HS alarm.
(3) Heater burnouts are not detected if the control output (heating) ON time
(Ton) is 190 ms or less.
(4) HS are not detected if the control output (heating) OFF time (Toff) is
190 ms or less.
• For models with HBA and HS alarms, an OR output is established
between the ALM 1 function and the HBA/HS alarm. If the ALM1 function
is to be used for HBA and HS alarms only, set 0 as the ALM1 type and do
not use ALM1.
• Turn the heater power ON simultaneously or before turning ON the E5CN
power. If the heater power is turned ON after turning ON the E5AN power,
the HBA will be activated.
• Control is continued even when the HBA or HS alarm is active.
• The rated current value may sometimes differ slightly from the actual current flowing to the heater.
Use the “heater current 1 value monitor,” “heater current 2 value monitor,”
“leakage current 1 monitor,” and “leakage current 2 monitor” parameters
to check the actual current being used.
44
Section 3-10
Using HBA and HS Alarms
• If there is little difference between the current in normal and abnormal
states, detection may become unstable. To stabilize detection, set a current value difference of at least 1.0 A for heaters of less than 10.0 A, and
at least 2.5 A for heaters of 10.0 A or more. If the heater current is too low,
loop the load line several times through a CT, as shown in the diagram
below. Looping it through twice will double the detection current.

3-10-2 Installing Current Transformers (CT)
• This function can be used with models that have the HBA and HS alarm.
Connect the CT in advance to terminals 14 and 15 (CT1) or 13 and 15
(CT2), and pass the heater power line through the CT's hole.
For specifications, models and dimensions of current transformers that
can be used with this Controller, see Appendix A Current Transformer

3-10-3 Calculating Detection Current Values
• Calculate the set value using the following equation:
Set value =
Normal current value + Burnout current value
2
• To set the current for heater burnout when two or more heaters are connected through the CT, use the value from when the heater with the smallest current burns out. If all of the heaters have the same current, use the
value from when any one of them burns out.
• Make sure that the following conditions are satisfied:
Heater with a current of less than 10.0 A:
(Current value at normal operation) − (Current value at heater burnout) ≥
1A
When the difference is less than 1 A, detection is unstable.
Heater with a current of 10.0 A or more:
(Current value at normal operation) − (Current value at heater burnout) ≥
2.5 A
When the difference is less than 2.5 A, detection is unstable.
• The setting range is 0.1 to 49.9 A. Heater burnout and HS are not
detected when the set value is 0.0 or 50.0.
When the set value is 0.0, the heater burnout alarm is always OFF, and
the HS alarm is always ON.
When the set value is 50.0, the heater burnout alarm is always ON, and
the HS alarm is always OFF.
• Set the total current value for normal heater operation to 50 A or less.
When a current value of 55.0 A is exceeded, ffff is displayed in the
“heater current 1 (and 2) value monitor” and “leakage current 1 (and 2)
monitor” parameters.

• Separate shift values can be set for the upper limit and lower limit of the
sensor input range for an infrared sensor as well as for a thermocouple or
platinum resistance thermometer with the “input shift type” set to INS2. If
different shift values are set for the upper limit and lower limit, then the
slope of the line will be different before and after applying the input shift.
For example, if the upper-limit value is set to 2°C and the lower-limit value
is set to 1°C, the input temperature will be shifted by 1.5°C for a 50%
input, i.e., by the average of the upper-limit and lower-limit values.
• Set the upper-limit value in the “upper-limit temperature input shift value”
parameter and the lower-limit value in the “lower-limit temperature input
shift value” parameter.

How to Calculate Input Shift Values for a 2-point Shift
When an ES1B Infrared Temperature Sensor is connected to the E5CN, an
offset of several degrees to several tens of a degree can occur.
For this reason, offset the readout value using a 1-point or 2-point shift as
described in this section. This offset occurs because a bias current for detecting a Controller sensor error flows to the output impedance of the infrared
temperature sensor.
Preparations
1,2,3...
1. Set a temperature range matching the input specifications of the infrared
temperature sensor. (The ES1B can be used with the E5AN only for a thermocouple/resistance thermometer multi-input type input.)
2. Prepare a thermometer capable of measuring the temperature of the control target as shown in Figure 1 so that a 1-point shift or 2-point shift can
be carried out.
3. The E5CN-@@@PH and E5CN-@@@PB have a built-in external power
supply for ES1B Infrared Temperature Sensors. These E5CN models can
be used as the power supply when using ES1B. When ES1B are used with
other E5CN models, provide a separate power supply for the Infrared Temperature Sensors.

1. Shift the Controller readout at two points, near room temperature and near
the value at which the temperature of the control target is to be controlled.
For this reason, check the control target temperature (B) and Controller
readout (A) with the control object temperature near room temperature and
near the set point.
2. Then use the following formulas to calculate the upper-limit and lower-limit
temperature input shift values based on the readout temperatures and desired temperatures.
The shift is illustrated in Figure 3.

readout (A) and control target temperature (B).
4. Here, offsets are set at two points, near room temperature and near the set
point. To improve accuracy within the measurement temperature range,
another point in the measurement temperature range other than the set
point should be set instead of room temperature.

In this example, we use the ES1A/ES1B K 0 to 260°C specification. In equations 1 and 2, the set temperature lower limit YL is 0°C and the set temperature upper limit YH is 260°C. Check the temperature of the control target.
The temperature input offset values can be calculated as shown below when
the Controller readout Y1 is 40°C for a room temperature X1 of 25°C and
when the Controller readout Y2 is 105°C for a set point temperature X2 of
110°C.

• Alarm hysteresis is set independently for each alarm in the “alarm hysteresis 1" to “alarm hysteresis 3” parameters (advanced function setting

• The default is 0.2 (°C/°F) for Controllers with Thermocouple/Resistance
Thermometer Multi-Inputs and 0.02% FS for Controllers with Analog
Inputs.
4-2-1
Standby Sequence
• The standby sequence can be used so that an alarm will not be output
until the process value leaves the alarm range once and then enters it
again.
• For example, with a lower limit alarm, the process value will normally be
below the set point, i.e., within the alarm range, when the power supply is
turned ON, causing an alarm to be output.
If the lower limit alarm with a standby sequence is selected, an alarm will
not be output until the process value increases above the alarm set value,
i.e., until it leaves the alarm range, and then falls back below the alarm set
value.
Restart
4-2-2
• The standby sequence is canceled when an alarm is output. It is, however, restarted later by the “standby sequence reset” parameter
(advanced function setting level). For details, refer to the “standby
sequence reset” parameter in SECTION 5 Parameters.
Alarm Latch
• The alarm latch can be used to keep the alarm output ON regardless of
the temperature once the alarm output has turned ON. The alarm output
will turn OFF when the power is turned OFF.
• (The alarm output can also be turned OFF by switching to the initial setting level, communications setting level, advanced function setting level,
or calibration level.)

Close in Alarm/Open in Alarm
• When “close in alarm” is set, the status of the alarm output function will be
output as is. When “open in alarm” is set, the status of the alarm output
function will be reversed before being output.
• Close in alarm/open in alarm can be set separately for each alarm.
• Close in alarm/open in alarm is set in the “alarm 1 open in alarm” to
“alarm 3 open in alarm” parameters (advanced function setting level).
• The default is n-o (close in alarm).
• When “alarm 1 open in alarm” (advanced function setting level) is set to
“open in alarm,” the heater burnout alarm and input error output are also
set to “open in alarm.”

• When an analog input is selected, scaling can be performed as needed
by the control application.
• Scaling is set in the “scaling upper limit,” “scaling lower limit,” and “decimal
point” parameters (initial setting level). These parameters cannot be used
when a temperature input is selected.
• The “scaling upper limit” parameter sets the physical quantity to be
expressed by the upper limit value of input, and the “scaling lower limit”
parameter sets the physical quantity to be expressed by the lower-limit
value of input. The “decimal point” parameter specifies the number of digits below the decimal point.
• The following figure shows a scaling example for a 4 to 20 mV input.
After scaling, the humidity can be directly read. Here, one place below the
decimal point is set.

Dead Band
• For heating/cooling control, the dead band is set with the set point as its
center. The dead band width is the set value of the “dead band” parameter (adjustment level). Setting a negative value produces an overlapping
band.
• If an overlapping band is set, the bumpless function may not operate
when switching between manual operation and automatic operation.
• The default is 0.0 EU for Controllers with Thermocouple/Resistance Thermometer Multi-Inputs and 0.00% FS for Controllers with Analog Inputs.

If the heating characteristics and cooling characteristics of the control object
are very different and good control characteristics cannot be achieved with the
same PID constants, the cooling coefficient can be used to adjust the proportional band (P) for the control output assigned to the cooling side. Use this to
achieve balanced control between the heating side and cooling side. The proportional bands (P) for the control outputs assigned to the heating/cooling
sides can be calculated using the following equations.
P for control output assigned to heating side = P
P for control output assigned to cooling side = P for control output assigned to
heating side × cooling coefficient
The cooling coefficient is multiplied by the P for the control output assigned to
the heating side to obtain control with characteristics that differ from those of
the control output assigned to the heating side.

• Of these, the multi-SP function, event inputs are used only for the number
(0 to 2) set in the “number of multi-SP uses” parameter (advanced function level).
• Event inputs (1 and 2) that are not used for the multi-SP function are
assigned using the “event input assignment 1” and “event input assignment 2” parameters (advanced function level).
• Event inputs can be used on E5CN-@@@B@ Controllers.

How to Use the Multi-SP Function
The multi-SP function allows you to set up to four set points (SP 0 to 3) in the
adjustment level. The set point can be switched by operating the keys on the
front panel or by using external input signals (event inputs).
Using Event Inputs
Event inputs can be used if the Controller supports the event input function
and if the “number of multi-SP uses” parameter is set to 1 or 2.

Note
Event inputs can be used on E5CN-@@@B@ Controllers. Turn the event
inputs ON or OFF while the E5AN is turned ON. Event input ON/OFF changes
are detected for inputs of 50 ms or longer.
Using Key Operations
You can select any of the set points 0 to 3 by changing the set value of the
“multi-SP uses” parameter. The “multi-SP uses” display conditions are as follows:
• If the Controller does not support event inputs, the “multi-SP uses” parameter must be set to ON.
• If the Controller supports event inputs, the “number of multi-SP uses”
parameter must be set to 0 and the “multi-SP uses” parameter must be
set to ON.
The following table shows the relationship between the “multi-SP uses”
parameter set value and the selected set point.

Set Point Limiter
The setting range of the set point is limited by the set point limiter. The set
point limiter is used to prevent the control target from reaching abnormal temperatures. The upper- and lower-limit values of the set point limiter are set
using the “set point upper limit” and “set point lower limit” parameters in the
initial setting level. When the set point limiter is reset, the set point is forcibly
changed to the upper- or lower-limit value of the set point limiter if the set point
is out of the limiter range. Also, when the input type and temperature unit are
changed, the set point limiter is forcibly reset to the sensor setting range.

Using the SP Ramp Function to Limit the SP Change Rate
SP Ramp
The SP ramp function is used to restrict the width of changes in the set point
as a rate of change. When the SP ramp function is enabled and the change
width exceeds the specified rate of change, an area where the set point is
restricted will be created, as shown in the following diagram.
During the SP ramp, control will be performed not for the specified set point
but rather for the set point restricted by the rate of change set for the SP ramp
function.
SP

Point of change
The rate of change during SP ramp is specified using the “SP ramp set value”
and “SP ramp time unit” parameters. The “SP ramp set value” parameter is
set to OFF by default, i.e., the SP ramp function is disabled.
Changes in the ramp set point can be monitored in the “Set point during SP
ramp” parameter (operation level). Use this parameter when monitoring SP
ramp operation.
The SP ramp function operates in the same way when switching the set point
using the multi-SP function.

If the SP ramp function is enabled when the Controller is turned ON or when

point using the SP ramp function in the same way as when the set point is
changed. In this case, operation is carried out with the process value treated
as the set point before the change was made. The direction of the SP ramp
changes according to the relationship between the process value and the set
point.

4-11-1 Alarm Delays
• Delays can be set for the alarm outputs. ON and OFF delays can be set
separately for alarms 1, 2, and 3. The ON and OFF delays for alarm 1
function only for the alarm function. If the alarm output 1 is set to be output as an OR with other alarm functions (i.e., the heater burnout alarm,
HS alarm, or input error output alarm), the delays will not function for the
other alarms. The ON and OFF delays for alarms 1, 2, and 3 also apply to
the individual ALM1, ALM2, and ALM3 indicators and to communications
status. The alarm ON delays will also function when power is turned ON
or when moving from initial setting level to operation level (i.e., to software
resets). All outputs will turn OFF and the OFF delays will not function
when moving to the initial setting level or when an alarm is output for a
heater burnout error.

• If an alarm turns OFF and then back ON during the ON delay time, the
time will be remeasured from the last time the alarm turns ON. Also, if an
alarm turns ON and then back OFF during the OFF delay time, the time
will be remeasured from the last time the alarm turns OFF.

Loop Burnout Alarm
4-12 Loop Burnout Alarm
4-12-1 Loop Burnout Alarm (LBA)
• With a loop burnout alarm, there is assumed to be an error in the control
loop if the control deviation (SP − PV) is greater than the threshold set in
the “LBA level” parameter and if the control deviation is not reduced by at
least the value set in the “LBA detection band” parameter within the LBA
detection time.
• Loop burnout alarms are detected at the following times.

If the control deviation is reduced in the area between 1 and 2 (i.e., the set
point is approached) and the amount the control deviation is reduced is at
least equal to the LBA band, the loop burnout alarm will remain OFF.
The process value is within the LBA level between 3 and 4, and thus loop
burnout alarms will not be detected. (The loop burnout alarm will remain OFF.)
If the process value is outside the LBA level between 4 and 5 and the control
deviation is not reduced by at least the LBA band within the LBA detection
time, the loop burnout alarm will turn ON.
If the control deviation is reduced in the area between 5 and 6 (i.e., the set
point is approached) and the amount the control deviation is reduced is at
least equal to the LBA band, the loop burnout alarm will turn OFF.
If the control deviation is reduced in the area between 6 and 7 (i.e., the set
point is approached) and the amount the control deviation is reduced is less
than the LBA band, the loop burnout alarm will turn ON.
• If the LBA detection time, LBA level, LBA detection band, and PID settings are not appropriate, alarms may be detected inappropriately or
alarms may not be output when necessary.
• Loop burnout alarms may be detected if unexpectedly large disturbances
occur continuously and a large deviation does not decrease.
• If a loop burnout occurs when the set point is near the ambient temperature, the temperature deviation in a steady state may be less than the LBA
level, preventing detection of the loop burnout.
• If the set point is so high or low that it cannot be reached even with a saturated manipulated variable, a temperature deviation may remain even in
a steady state and a loop burnout may be detected.

Section 4-12
Loop Burnout Alarm
• Detection in not possible if a fault occurs that causes an increase in temperature while control is being applied to increase the temperature (e.g.,
an SSR short-circuit fault).
• Detection in not possible if a fault occurs that causes a decrease in temperature while control is being applied to decrease the temperature (e.g.,
a heater burnout fault).

4-13-1 Manual Operation
• The manipulated variable can be set in manual mode if the “PV/MV”
parameter is displayed in the manual control level. The final MV used in
automatic mode will be used as the initial manual MV when moving from
automatic mode to manual mode. In manual mode, the change value will
be fixed immediately and reflected in the actual MV.
• The automatic display return function will not operate in manual mode.
• Balanceless-bumpless operation will be performed for the MV when
switching from manual operation to automatic operation. (See note.)
• If a power interruption occurs during manual operation, manual operation
will be restarted when power is restored using the same MV as when
power was interrupted.
• Switching between automatic and manual operation is possible for a maximum of one million times.
• Manual operation can be used only for PID control.
Note
In balanceless-bumpless operation, the MV before switching is used initially
after the switch and then gradually changed to achieve the proper value after
switch to prevent radical changes in the MV after switching operation.

(2) The difference between the transfer output value and the linear current
output value is illustrated in the following figure.
If the linear output is used as the transfer output when the linear current
output type is set to 4 to 20 mA, 4.0 mA will be output for 0% and 20.0 mA
will be output for 100%.
When a linear output is used for the control output, 3.7 mA is output for
0% and 20.3 mA is output for 100% when the control output for heating
is selected to ensure that the control object is controlled at 0% and 100%.

Transfer Scaling
• Reverse scaling is possible by setting the “transfer output lower limit”
parameter larger than the “transfer output upper limit” parameter. If the
“transfer output lower limit” and “transfer output upper limit” parameters
are set to the same value when 4 to 20 mA is set, the transfer output will
be output continuously at 0% (4 mA).
• If the SP, SP during SP ramp, or PV is selected, the “transfer output lower
limit” and “transfer output upper limit” parameters will be forcibly initialized
to the respective upper and lower setting limits for changes in the upper
and lower limits of the SP limiter and the temperature unit.
If the MV for heating or MV for cooling is selected, the “transfer output
lower limit” and “transfer output upper limit” parameters will be initialized
to 100.0 and 0.0, respectively, when a switch is made between standard
control and heating/cooling control using the “standard or heating/cooling”
parameter.
• The output current when the linear current type is set to 4 to 20 mA, the
transfer output upper limit is set to 90.0, and the transfer output lower limit
is set to 10.0 is shown in the following graph.
• For scaling from 0.0% to 100.0%, the output for −5.0 to 0.0 will be the
same value as for 0.0%, and the output for 100.0 to 105.0 will be the
same value as for 100.0%

Starting Method
Any of the following three methods can be used to start the simple program.
• Setting the “program start” parameter to STRT.
• Turning ON an event input. (The program start must be assigned to an
event input. See note.)
• Starting with an Operation Command using communications. (When the
program start is not assigned to an event input.)
Note
When an event input is used to start and reset the simple program, writing is
performed to EEPROM. Be sure to consider the write life (1 million writes) of
the EEPROM in the system design. When the program start is assigned to an
event input, the “program start” parameter will function as a monitor display,
and the RSET/STRT displays can be used to check when the event input has
started or reset the simple program. When this is done, the “program start”
parameter functions as a monitor display only and cannot be changed using
key operations. If the “program pattern” parameter is set to OFF, the event
input assignment setting will be initialized to “none.”

The wait band is the fixed band within which the process value is stable in
respect to the set point. The soak time is measured within the wait band. The
timer that measures the soak time operates only when the process value is
within the wait band around the set point (i.e., SP ± wait band). In the following
diagram, the timer will be stopped between the start and (1), (2) and (3), and
(4) and (5) and will measure the time only between (1) and (2), (3) and (4),
and (5) and the end.
Note
If the wait band is set to OFF, the wait band will be treated as infinity and the
timer will measure time continuously after changing from RSET to STRT.

Program End Output
When the “program pattern” parameter is changed from OFF to STOP or
CONT, the “alarm 1 output assignment” parameter will automatically be set to
the END output. The ALM1 indicator will not light while the END output is set.
(When the “program pattern” parameter is changed from STOP or CONT to
OFF, the “alarm 1 output assignment” parameter will automatically be initialized to ALM1.) The output assignment parameters can also be used to assign
the program END output to any output.
The program END output is also provided in communications status.
Clearing the Program End Status
The program END output and display will be cleared when the “program start”
parameter is changed from STRT to RSET. The setting is changed from STRT
to RSET while the “program start” parameter is displayed.
The program END status can also be cleared using an event. If the program
start function is assigned to an event, however, the program end status cannot
be cleared from the “program start” parameter display, which will function only
as a monitor display.
Operating Procedure
Perform the following procedure to use the simple program function.
In this example, the program pattern will be set to STOP, the soak time to
10 min, and the wait band to 3.

The control must be set to 2-PID
control.
These parameters set PID control constants. PID constants are automatically
set when AT or ST is executed.
P action: Refers to control in which the MV is proportional to the deviation
(control error).
I action: Refers to a control action that is proportional to the time integral of
the deviation. With proportional control, there is normally an offset
(control error). Proportional action is thus used in combination with
integral action. As time passes, this control error disappears, and
the control temperature (process value) comes to agree with the set
point.
Function
D action: Refers to a control action that is proportional to the time derivative of
the control error. The proportional control and integral control correct for errors in the control result, and thus the control system is
late in responding to sudden changes in temperature. The derivative
action increases the MV in proportion to the slope of the change in
the temperature as a corrective action.

Number of Multi-SP Uses
Event inputs must be supported.
Multi-SP is a function for setting set points 0 to 3 in advance, and switching
between these set points using the ON/OFF combinations of event inputs 1
and 2.
Function
The “number of multi-SP uses” parameter is used when the number of preset
set points is either two or four.
This parameter determines whether the “event input assignment 1” and “event
input assignment 2” parameters are displayed.
The “number of multi-SP uses” parameter displays which functions are
assigned to event inputs 1 and 2.

manual), or “PRST” (program start) has been assigned to one event input, the other event can be assigned only to either of the remaining two
settings.
(2) “PRST” (program start) can be set only when the “program pattern” parameter has not be set to OFF.
If the “program pattern” parameter is set to OFF (i.e., if the simple program mode is not selected) when “PRST” (program start) is set, the assignment of the input will automatically be changed to “NONE.”
• Default: 1
Multi-SP switching by event inputs can be used with Controllers that have

User Calibration
The E5CN/E5CN-U is correctly calibrated before it is shipped from the factory,
and normally need not be calibrated by the user.
If, however, it must be calibrated by the user, use the parameters for calibrating temperature input and analog input. OMRON, however, cannot ensure the
results of calibration by the user. Also, calibration data is overwritten with the
latest calibration results. The default calibration settings cannot be restored
after user calibration. Perform user calibration with care.

The input type selected in the parameter is used for calibration. The input
types are as follows:
Controllers with Thermocouple/Resistance Thermometer Multi-inputs
• Thermocouple:

• Infrared temperature sensor:

• Analog input:
1 type
• Platinum resistance thermometer: 5 types
Controllers with Analog Inputs
• Current input: 2 types
• Voltage input: 3 types
6-2-2
Registering Calibration Data
The new calibration data for each item is temporarily registered. It can be officially registered as calibration data only when all items have been calibrated
to new values. Therefore, be sure to temporarily register all items when you
perform the calibration. When the data is registered, it is also recorded that
user calibration has been performed.
Prepare separate measuring devices and equipment for calibration. For
details on how to handle measuring devices and equipment, refer to the
respective instruction manuals.
6-3
Thermocouple Calibration (Thermocouple/Resistance
Thermometer Input)
• Calibrate according to the type of thermocouple: thermocouple 1 group
(input types 5, 7, 11, 12, 15) and thermocouple 2 group (input types 6, 8,
9, 10, 13, 14, 16, 17, 18, 19, 20, 21, 22).
• When calibrating, do not cover the bottom of the Controller. Also, do not
touch input terminals/pins (terminals 4 and 5 on the E5CN, and pins 1
and 2 on the E5CN-U) or compensating conductors.

can be substituted with the cold junction compensator and the compensating conductor for thermocouple K.
■ Connecting the Cold Junction Compensator
Correct process values cannot be obtained if you touch the contact ends of
the compensating conductor during calibration of a thermocouple. Accordingly, short-circuit (enable) or open (disable) the tip of the thermocouple inside
the cold junction compensator as shown in the figure below to create a contact or non-contact state for the cold junction compensator.

Error Displays
When an error occurs, the error contents are shown on the No. 1 display.
This section describes how to check error codes on the display, and the actions to be taken to remedy the
problems.
s.err
Input Error
Meaning
The input value has exceeded the control range. (See note.)
Note Control Range
Resistance thermometer, thermocouple input: Temperature setting lower limit − 20°C to temperature
setting upper limit + 20°C
(Temperature setting lower limit − 40°F to temperature
setting upper limit + 40°F)
ES1A/ES1B input:
Same as input indication range
−5% to +105% of scaling range
Analog input
Action
Check the wiring of inputs for miswiring, disconnections, and short-circuits and check the input type.
If no abnormality is found in the wiring and input type, turn the power OFF then back ON again.
If the display remains the same, the Controller must be replaced. If the display is restored, then the probable
cause is electrical noise affecting the control system. Check for electrical noise.
Operation at Error
After an error occurs, the error is displayed and the alarm outputs function as if the upper limit has been
exceeded.
When the “input error output” parameter in the advanced function level is set to ON, the alarm 1 output turns
ON whenever an input error occurs.
An error message is displayed when the PV, PV/SP, or PV/MV is displayed.
Note When the manual MV, MV at stop, or MV at PV error is set, the control output corresponds to the set
value.

HB Error (See note.)
Meaning
There is an error in internal circuits.
Action
First, turn the power OFF then back ON again. If the display remains the same, the Controller must be
repaired. If the display is restored, then the probable cause is electrical noise affecting the control system.
Check for electrical noise.
Action
The control outputs and alarm outputs turn OFF. An error message is displayed when the PV, PV/SP, or PV/MV
is displayed.
When the manual MV, MV at stop, or MV at PV error is set, the control output corresponds to the set value.
For alarm outputs, the operation indicators and status normally turn OFF, but they will turn ON if the “close in
alarm” parameter for alarms 1, 2, or 3 in the advanced function setting level is set to n-c (Close in alarm).
Note Applies to the E5CN-@@H@.
e111
Memory Error
Meaning
Internal memory operation is in error.
Action
First, turn the power OFF then back ON again. If the display remains the same, the Controller must be
repaired. If the display is restored, then the probable cause is electrical noise affecting the control system.
Check for electrical noise.
Operation at Error
Control output and alarm output turn OFF. (Current output is approx. 0 mA).

When either heater burnout or HS is detected, the HA indicator lights and the No. 1 display flashes for the
applicable “heater current 1 value monitor,” “heater current 2 value monitor,” “leakage current 1 monitor,” or
“leakage current 1 monitor” parameters in the operation level and adjustment level. Control continues, allowing
normal operation.

Initialized if the input type, temperature unit, scaling upper/lower limit, or SP upper/
lower limit is changed when the transfer output type is SP, ramp SP, or PV.
(When initialized by the initializing settings, it is initialized to 100.0/0.0.)
(2) The setting range depends on whether control output 1 is a linear output or pulse output.
(3) When setting CWF, either CompoWay/F or SYSWAY can be used as the communications protocol.
(CompoWay/F and SYSWAY are automatically identified by the command frames.)
(4) P.END (program end output) can be set when the program pattern is not set to 0 (OFF).
