NOTICE

Be sure to observe these precautions to ensure safe use.

(1) Do not wire unused terminals. (2) Be sure to wire properly with correct polarity of terminals. (3) To reduce induction noise, separate the highĆvoltage or largeĆcurrent power lines from other lines,

and avoid parallel or common wiring with the power lines when you are wiring to the terminals. We recommend using separating pipes, ducts, or shielded lines.

(4) Do not use this product in the following places:

• Places subject to dust or corrosive gases (in particular, sulfide gas and ammonia gas)

• Places subject to high humidity, condensation or freezing

• Places subject to direct sunlight

• Places subject to vibration and large shocks

• Places subject to splashing liquid or oily atmosphere

• Places directly subject to heat radiated from heating equipment

• Places subject to intense temperature changes

(5) To allow heat to escape, do not block the area around the product. (Ensure that enough space is

left for the heat to escape.)

• Do not block the ventilation holes on the casing.

(6) When you draw out or draw in the internal mechanism or the terminal unit from the housing,

never touch electrical components inside or subject the internal mechanism to shock. (7) Cleaning: Do not use paint thinner or the equivalent. Use standard grade alcohol to clean the product. (8) Use specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. (9) Allow as much space as possible between the E5AN and devices that generate powerful highĆfreĆ

quency noise (e.g. highĆfrequency welders, highĆfrequency sewing machines) or surges. (10) When executing selfĆtuning, turn the load (e.g. heater) ON simultaneously or before you turn the

the main unit ON. If you turn the the main unit ON before turning the load ON, correct selfĆtuning

results and optimum control may no longer be obtained. (11) Use a 100 to 240 VAC (50/60 Hz), 24 VAC (50/60 Hz) or 24 VDC power supply matched to the power

specifications of the E5AN. Also, make sure that rated voltage is attained within two seconds of

turning the power ON. (12) 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 comĆ

ponent). (13) When mounting a noise filter on the power supply, be sure to first check the filter's voltage and

current capacity, and then mount the filter as close as possible to the E5AN. (14) Use within the following temperature and humidity ranges:

• Temperature: Ć10 to 55_C, Humidity: 25 to 85% (with no icing or condensation)

If the E5AN is installed inside a control board, the ambient temperature must be kept to under 55_C, including the temperature around the E5AN. If the E5AN is subjected to heat radiation, use a fan to cool the surface of the E5AN to under 55_C.

(15) Store within the following temperature and humidity ranges:

• Temperature: Ć25 to 65_C, Humidity: 25 to 85% (with no icing or condensation)

(16) Never place heavy objects on, or apply pressure to the E5AN as it may cause it to deform and deteriĆ

orate during use or storage. (17) Avoid using the E5AN in places near a radio, television set, or wireless installation. These devices

can cause radio disturbances which adversely affect the performance of the E5AN. (18) Allow at least 30 minutes for the E5AN to warm up. (19) Locate a switch or circuit breaker and clearly indicate its position so that the operator can immediĆ

ately turn the E5AN OFF.

JTo ensure

prolonged use

Use the temperature in the following operating environment:

Temperature : -10 to +55°C (icing and condensation not allowed)

Humidity : 25 to 85%

When the temperature controller is incorporated in a control panel, make

sure that the controller's ambient temperature and not the panel's ambiĆ

ent temperature does not exceed 55°C.

The life of electronic equipment such as temperature controllers is inĆ

fluenced not only by the life determined by the relay switching count but

also by the life of the electronic components used internally. The service

life of components is dependent on the ambient temperature: the higher

the ambient temperature becomes, the shorter the service life becomes,

and vice versa. For this reason, the service life of the temperature controlĆ

ler can be extended by lowering its internal temperature.

Gang-mounting two or more temperature controllers, or mounting temperĆ

ature controllers above each other may cause heat to build up inside the temĆ

perature controllers, which will shorten their service life. When mounting

temperature controllers like this, forced cooling measures such as a cooling

fan for cooling the temperature controllers must be taken into consideration.

Prevent only the terminal block from being cooled. Otherwise, this may

result in a measurement error.

JTo reduce the

influence o f noise

JTo ensure

high–precision measurement

To reduce induction noise, the leads on the temperature controller's terĆ

minal block must be wired separately from large-voltage/large-current

power leads. Also, avoid wiring leads in parallel with power leads or in the

same wiring path. Other methods such as separating conduits and wiring

ducts, or using shield wire are also effective.

Attach a surge absorber or noise filter to peripheral equipment that generĆ

ates noise (in particular, motors, transformers, solenoids, or other equipĆ

ment that has a magnetic coil or other 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.

Also, install the temperature controller as far away as possible from equipĆ

ment that generates strong, high frequency (e.g. high-frequency welders,

high-frequency sewing machines) or surges.

When the thermocouple leads are extended, be sure to use a compensating

lead wire matched to the type of thermocouple.

When the platinum resistance detector leads are extended, use the lead

having the smallest resistance to equalize the resistance of the three leads.

Install the temperature controller so that it is horizontal.

If there is a large error in the measurement values, make sure that input

compensation has been set correctly.

3.7 Executing ON/OFF Control

In ON/OFF" control, the control output turns OFF when the currently controlled temperature reaches a preset set point. When the manipulated variable turns OFF, the temperature begins to fall and the control turns ON again. This operation is repeated at a certain point. At this time, how much the temperature must fall before control turns ON again is deterĆ mined by the hysteresis (OUT1)" parameter. Also, how much the manipĆ ulated variable must be adjusted in response in the increase or decrease in the process value is determined by direct/reverse operation" parameter.

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 Program Execution When Set Point Is Changed

1. The set point at the start of program execution differs from the set point (See Note 1) when the previous SRT was executed.

2. The difference between the temperature at start of program execution is larger than (current proportional band 1.27+4_C) or the (ST stable range) whichever is larger.

3. The temperature at the start of program execution is smaller than the set point during reverse operation, and is larger than the set point during direct operation.

4. No reset from input error

1. The new set point differs from the set point (See Note 1) used when the previous SRT was executed.

2. The set point change width is larger than (current proportional band 1.27+4_C) or the ( ST stable range) whichever is larger.

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 in a stable state (See Note 2). (An equilibrium state is acceptable when the output is 0% when the power is turned ON.)

3.10 Heater Burnout Alarm (HBA)

3.10Heater Burnout Alarm (HBA)

JHBA detection

To CT terminal

Heater lead

JOperating

conditions

Ă• Heater burnout detection works as follows.

(1) Connect the current transformer (CT) to terminal Nos. 14 and 15,

and insert the heater lead through the CT hole. For specifications, models and external dimensions of current transformers that can be used on this controller, see Appendix, About Current TransĆ former (CT)."

(2) When current flows through this lead, the current transformer

generates AC current proportional to the current value. The E5AN measures this AC current to calculate the current flowing to the heater.

(3) If the heater is burned out, the current measured at the current

transformer decreases. This value is compared with the value set as the heater burnout set value", and the output becomes active as the heater burnout alarm.

Ă• Set the heater burnout set value in the heater burnout detection" paĆ

rameter (adjustment level). To monitor the current value of the current transformer, use the heater current monitor" parameter.

Ă• When HBA function, is not used set the heater burnout" parameter

(advanced function setting level) to OFF".

Ă• The HBA function can be used when the option unit E53ĆAKB,

E53ĆAK01, or E53ĆAK03 is mounted on the E5AN. Be sure to connect the CT to the E5AN, and pass the heater lead through the CT hole.

Ă• Turn the heater ON at the same time as or before turning the E5AN ON.

If the heater is turned ON after turning the E5AN ON, the heater burnĆ out alarm will activate.

Ă• Control is continued even if the heater burnout alarm is active. (That is,

the E5AN attempts to control the heater on which the heater burnout alarm has not occurred.)

Ă• The heater burnout alarm is detected when the control output is continĆ

uously ON for 190 ms or more.

Ă• The rated current value may sometimes differ slightly from the actual

current flowing to the heater. Check the current value in an actual operĆ ating state in the heater current monitor" parameter.

Ă• If there is little difference between the current in a normal state and the

current in the burnout state, detection may become unstable. On a heatĆ er of current 10.0 A or less, maintain a difference of 1.0 A or more. On a heater of current 10.0 A or more, maintain a difference of 2.5 A or more.

Ă• The HBA function cannot be used when the heater is controlled by a

phase control system or cycle control system. Also, 3Ćphase heaters canĆ not be used.

When heater burnout is detected on a 3Ćphase heater, use the K2CUĆFjjAĆjGS

(with gate input terminal). See the respective data sheet for details.

3.10Heater Burnout Alarm (HBA)

JHow to calculate

detection current values

Ă• Calculate the set value by the following equation:

Set value =

(current value at normal operation + current value at heater burnout)

Ă• To set the value of the heater burnout when two or more heaters are conĆ

nected through the CT, use the curent value of the smallest heater conĆ nected. OR the current value when one of the heaters burns out if all the heaters have the same current value.

Ă• Make sure that the following conditions are satisfied:

Heater of current 10.0 A or less:

Current value at normal operation Ć

current value at heater burnout y 1 A

(When the resultant current is less than 1 A, detection is unstable.)

Heater of current 10.0 A or more:

Current value at normal operation Ć

current value at heater burnout y 2.5 A

(When the resultant current is less than 2.5 A, detection is unstable.)

Ă• The setting range is 0.1 to 49.9 A. Heater burnout is not detected when

the set value is 0.0" or 50.0". When the set value is 0.0", the heater burnout alarm is set to OFF", and if the set value is 50.0", the heater burnout alarm is set to ON".

Ă• Set the total current value at normal heater operation to 50 A or less.

When set to 55.0 A",  " is displayed in the heater current moniĆ tor" parameter.

CHAPTER 3 BASIC OPERATION

3.11 Requests during Operation

1) About four seconds is required for outputs to turn ON when the power

is turned ON. Take this into consideration when the temperature conĆ

troller is incorporated into a sequence circuit.

2) Allow at least 30 minutes for warming up.

3) When self-tuning is used, turn the temperature controller and load

(e.g. heater) ON simultaneously or turn the load ON before the temĆ

perature controller. If the load is turned ON before the temperature

controller, correct self-tuning and optimum control are no longer

possible.

When operation is started after warm-up, turn the power OFF once

after warm-up is completed, and then turn the temperature controlĆ

ler and load ON simultaneously. (Instead of turning the temperature

controller power ON again, moving from the STOP to the RUN mode

also is possible.)

4) The temperature controller may be subject to the influence of radio

interference if used near a radio, TV or wireless equipment.

Ă• The input temperature range of nonĆcontact temperature sensors can

be shifted by setting an individual value for the upper and lower points of the sensor range. This means that the shift can be applied equally across the range with separate values for each end of the range. For example, if the upperĆlimit value is set to 2_C" and the lowerĆlimit value is set to 1_C", the sensor range is shifted by an average of 1.5_C at 50% input.

Ă• Set the upperĆlimit value in the upperĆlimit temperature input shift

JHow to calculate input shift values (2-point shift)

When the nonĆcontact temperature sensor model ES1A is connected to the E5AN, an offset of several to several tens of a degree can occur. For this reason, offset the readout value by 1Ćpoint or 2Ćpoint shift as described in this item. This offset occurs as a bias current for detecting controller sensor error flows to the output impedance of the nonĆcontact temperature sensor. 2Ćpoint shift can be carried out only on nonĆcontact temperature sensors, and cannot be set for other input types.

[Preparations]

(1) Set to the temperature range matching the input specifications of the

nonĆcontact temperature sensor. (ES1A is supported only in thermoĆ couple input types on the E5AN.)

(2) Prepare a thermometer capable of measuring the temperature of the

control target as shown in Figure 1 so that 1Ćpoint shift or 2Ćpoint shift can be carried out.

Ă• Alarm hysteresis is set independently for each alarm in the alarm hysĆ

Ă• Standby sequence" is a function which allows the alarm outputs to be

temporarily disabled while the first alarm condition occurs. From here on, the alarm output is active for future alarm conditions.

Ă• For example, in a standard heating application, if you used the standard

low alarm", the alarm would be active from switching the controller ON. However, with Standby Sequence", the alarm output is disabled during the first warmup, and the temperature has to rise above the alarm set point before the alarm can become active. Then, if the temperĆ ature falls below the alarm set point, the output is active.

If the heating and cooling characteristics of the control target greatly difĆ fer, preventing satisfactory control characteristics from being obtained by the same PID constants, adjust the proportional band (P) at the cooling side using the cooling coefficient to balance control between the heating and cooling sides. In heating and cooling control, P at the heating or coolĆ ing side is calculated by the following formula:

Heating side P = P Cooling side P = Pcooling coefficient

The cooling coefficient is applied to Control output 1 side P to obtain conĆ trol whose characteristics (Control output 2 side P) differ from those on the Control output 1 side.

Proportional band

Integral time

Derivative time

This parameter sets the PID parameters. Note that PID is automatically set when AT and ST are executed.

Proportional action : P refers to control in which the MV is proportional to the deviĆ

ation (control error).

Function

Integral action : I gives a control action that is proportional to the time integral

of the control error. With proportional control, there is norĆ

mally an offset (control error). So, proportional action is used

in combination with integral action. As time passes, this conĆ

trol error disappears, and the set point comes to agree with the

control temperature (process value).

Derivative action : D gives a control action that is proportional to the time derivaĆ

tive of the control error. As proportional control and integral

control correct for errors in the control result, the control sysĆ

tem will be late in responding to sudden changes in temperaĆ

ture. Derivative action enables control that is proportional to

a predicted process output to correct for future error.

ST self-tuning

The control must be set to temperature input, standard control and 2-PID control.

Ă• The ST (selfĆtuning) function executes tuning from the start of program execution

to calculate PID constants matched to the control target. When the ST function is in

operation, be sure to turn the power supply of the load connected to the control outĆ

put ON simultaneously with or before starting operation of the E5AN.

Parameter Setting Range Unit Default

Control period (OUT2)

Ă• This parameter sets the output period. Set the control period taking the control charĆ

acteristics and the electrical life expectancy of the relay into consideration.

Ă• In a standard control system, use the control period (OUT1)" parameter. The conĆ

trol period (OUT2)" parameter cannot be used.

Ă• Whenever control output 1 is the current output, control period (OUT1)" cannot be

used.

Ă• In a heating and cooling control system, the control period can be set independently

for heating and cooling. Use the control period (OUT1)" parameter to set the heatĆ

ing side control period, and use the control period (OUT2)" parameter to set the

cooling side control period.

Parameter Setting Range Unit Default

Control period (OUT1) 1 to 99 Second 20 Control period (OUT2) 1 to 99 Second 20
