Precautions for Safe Use

Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects on the performance and functions of the product. Not doing so may occasionally result in unexpected events.

1) The product is specifically designed for indoor use only. Do not use 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.

2) Use and store the Digital Temperature Controlle r within the ra te d am b ien t tem p er a tu re and hum id i ty. 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.

3) To allow heat to escape, do not block the area around the product. Do not block the ventilation holes on the product.

4) Be sure to wire properly with correct polarity of terminals.

5) Use the specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. For open-wired connection, use stranded or solid copper wires with a gage of AWG24 to AWG14 (equ al to a crosssectional area of 0.205 to 2.081 mm size and type or two crimp terminals can be inserted into a single terminal.

6) Do not wire the terminals which are not used.

7) 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 an d using separat e 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.

8) Use this product within the rated load and power supply.

9) Make sure that the rated voltage is attained within 2 seconds of turning ON the po we r b y using a switch or relay contact. If the voltage is applied gradually, the power may not be reset or output malfunctions may occur.

10) Make sure that the Temperature Controller has 30 minutes or more to warm up after turning ON the power before starting actual control operations to ensure the correct temperature display.

11) 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 T emperat ure Co ntroller. 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.

12) 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 m arked as a disconnecting means for this unit.

13) 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.

). (The stripping length is 5 to 6 mm.) Up to two wires of the same

Page 11

14) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.

15) Design system (control panel, etc) considering the 2 seconds of delay that the controller’s output to be set after power ON.

16) The output may turn OFF when shifting to certain levels. Take this into consideration when performing control.

17) The number of EEPROM write operations is limited. Therefore, use RAM write mode when frequently overwriting data during communications or other operations.

18) Always touch a grounded piece of metal before touching the Digital Temperature Controller to discharge static electricity from your body.

19) Control output that is voltage output is not isolated from the internal circuits.When using a grounded thermocouple,do not connect any of the control output terminals to ground. (Doing so may result in an unwanted circuit path, causing error in the measured temperature.)

20) When replacing the body of the Digital Temperature Controller, check the condition of the terminals. If corroded terminals are used, contact failure in the terminals may cause the temperature inside the Digital Temperature Controller to increase, possibly resulting in fire. If the terminals are corroded, replace the case as well.

21) Use suitable tools when taking t he Dig ita l T em p erature Controller apart for dispos a l. Sh ar p pa rt s ins ide th e Digital Temperature Controller may cause injury.

22) Check the orientation of the connectors on the Conversion Cable before connecting the Conversion Cable. Do not force a connector if it does not connect smoothly. Using excessive force m ay damage the connector.

23) Do not place heavy object on the Conversion Cable, bend the cable past its natural bending radius, or pull on the cable with undue force.

24) Do not connect or disconnect the Conversion Cable while communications are in progress. Product faults or malfunction may occur.

25) Make sure that the Conversion Cable

26) Do not touch the connectors on the Conversion Cable with wet hands. Electrical shock may result.

s metal components are not touching the external power terminals.

O 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 tem perature must be kept to under 55°C, including the temperature around the Controller.

The service life of electronic devices like Temperature Con trolle rs is dete rm ined not only b y the nu mbe r of times the relay is switch ed but also by the s ervice lif e of interna l electro nic c omponen ts. Com pone nt 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.

O 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 per ipher al d evices th at ge nerate 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 a nd devices that ge nerate powerful high frequencies (high-freq u ency we lde rs , high-frequency sewing machines, etc.) or surge.

O 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.

O 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.

Precautions for Operation

1) It takes approximately 2 seconds for the outputs to turn ON from after the power supply is tu rn ed ON. Du e consideration must be given to this time when incorporating Temperature Controllers into a control panel or similar device.

2) Make sure that the Temperature 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.

3) 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 Te mperature Controller before turning ON power for the load, self-tuning will not be performed properly and op timum control will not be achieved. When starting operation after the Temperature Controller has warmed up, tu rn OFF the power and then turn it ON again at the same time as tu rn ing ON power for the loa d. (In ste ad of turnin g th e Temperature Controller OFF and ON again, switching from STOP mode to RUN mode can also be used.)

4) Avoid using the Controller in places near a radio, tele vision set, or wireless ins talling. The Controller may cause radio disturbance for these devices.

Page 32

I/O Configuration and Main Functions Section 1-2

Control Outputs • A con trol outp ut can be r elay, voltage, o r curren t outp ut, depending on the

model.

• With the E5CZ-@2M@@, alarm output 2 is used as control output (cooling) when heating/cooling control is selected. Therefore, use alarm 1 if an alarm is required while using heating/cooling control.

• With the E5AZ/E5EZ-@3@@@@, alarm output 3 is used as control output (cooling) when heating/cooling control is selected. Therefore, use alarms 1 and 2 if an alarm is required while using heating/cooling control.

Alarms • Alarms can be used with the E5CZ-@2M@@,or E5CZ-@2T@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” parame ter is set to ON, a larm o utput 1 turns ON when an input error occurs.

Control Adjustment • Optimum PID constants can be set easily by performing AT (auto-tuning)

or ST (self-tuning).

Event Inputs • The following functions can be executed using event inputs: switching set

points (multi-SP, 4 pts. max.), and switching RUN/STOP status, and switching between automatic and manual operation.

Setting Level Configuration and Key Operations Section 1-3

Protect Level • To switch to the protect level from either the operation level or the adjust-

ment level, simultaneously hold down the O and M keys for at least 3 seconds. (See note.) This level is for preventing unwant ed or accidental modification of parameters. Protected levels will not be displayed, and so the parameters in that level cannot be modified.

Note The key pressing time can be changed in “move to protect level

time” parameter (advanced function setting level).

Operation Level • The op eration 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 le vel, 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 HB alarm, 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 1 second.

Initial Setting Level • To move to the initial setting level from the operation level or the adjust-

ment level, press the O key for at least 3 seconds. The PV display flashes after 1 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 1 second. To move to the communications setting level, press the O key for less than 1 second. (When moving from the initial setting level to the operation level, all the indicators will light.)

Note Pressing the O key for at least 3 seconds in the oper ation 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 funct ion sett ing leve l, it is possible to move to the initial setting level.

• This level is for setting the automatic display return time, event input assignments, standby sequence, an

d alarm hysteresis.

Setting Level Configuration and Key Operations Section 1-3

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.

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. For details, refer to SECTION 5 Param- eters.

Moves in order after M key is pressed (if key is released within 1 s).

Parameter 1

Parameter 2

While the M key is being held down, the parameter will move each second in reverse order.

Parameter 2

After M key has been held down for 2 s.

1-3-2 Fixing Settings

Parameter 3

After M key is pressed

Parameter 4

Hold down the M key during this interval.

Parameter 3

After M key has been held down for 1 s.

• If you press the M key at th e final parameter, the display returns to the top parameter for the current level.

• To change parameter settings, s pecif y the settin g using the U or D key, and either leave the setting for at least 2 seconds or press the M key. This fixes the setting.

• When another level is selected after a setting has been changed, the contents of the parameter prior to the change are fixed.

• When you turn the power OFF, you must first fix the settings (b y pr essing the M key). The settings are sometimes not ch ang ed b y me rely pres sing the U or D keys.

• When the “input error output” parameter is set to ON, alarm output 1 turns ON when an input error occurs.

• When the HB alarm or the HS alarm is used with the E5CZ-@2M@@ with E53-CZH03 or E53-CZHB alarms are output across terminals 7 and 8.

• When the HB alarm or the HS alarm is used with the E5AZ-@3H@@@or the E5EZ-@3H@@@, alarms are output across terminals 9 and 10.

• On the E5CZ and E5CZ-U, when heating/cooling control is used, alarm output 2 becomes control output (cooling).

• On the E5AZ and E5EZ, when heating/cooling control is used, alarm output 3 becomes control output (cooling).

• For models that have a heater burnout alarm, an OR of alarm output 1 and the HB alarm/HS alarm is output. If ALM1 is to be used for HB alarm only, set the alarm 1 type to 0 and do not use alarm output 1.

Setting the Input Type Section 3-2

3-2 Setting the Input Type

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 (universalinput) and models with analog input. The settings differ depending on the model. Check to make sure which model you are using .

3-4 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 cons tants in th e “pro portion al band” (P), “int egral time” (I), and “derivative time” (D) parameters.

ON/OFF Control In ON/OFF control, the control output is turn ed ON wh en the proc ess valu e 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).

3-5 Setting Output Specifications

3-5-1 Control Periods

• Set the output periods (control periods). Though a shorter period provides better control performance, it is recommended that the control period be 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 (heating)” and “control period (cooling)” parameters in the initial setting level. The default is 20 seconds.

• T he “control period (cooling)” parameter is used only for heating/cooling control.

• When control output 1 is used as a current output, “control period (heating)” cannot be used.

Setting Output Specifications Section 3-5

3-5-2 Direct and Reverse Operation

• “Direct operation” increases the manipulated variable whenever the pro-

orev

cess value increases. “Reverse operation” decreases the manipulated variable whenever the process value increases.

Manipulated variable Manipulated variable

100%

Low temperature

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).

Operating Procedure In this example, the input type, temperature unit, direct/reverse operation, and

control period (heating) parameters are checked.

Input type = s (K thermocouple) Temperature unit = c (°C) Direct/reverse operation = or-r (reverse operation) Control period (heating) = 20 (seconds)

Operation Level

The operation level is displayed when the power is turned ON. The process value (PV) is at the top of the display, and the set point (SP) is at the bottom.

3-6-1 Changing the SP

• The set point cannot be changed when the “operation/adjustment protect” parameter is set to 3. For details, refer to 4-9 Using the Key Protect Level.

• To change the set point, press the U or D key in the “process value/set point” parameter (in the operation level), and set the desired set value. The new set point is selected two seconds after you have specified the new value.

• Multi-SP is used to switch between two or four set points. For details, refer to 4-5 Using Event Inputs for details.

Operating Procedure In this example, the set point is changed from 0°C to 200°C.

Operation Level

1. Normally, the “process value/set point” parameter is displayed. The set point is 0°C.

2. Use the U and D keys to set the set point to 200°C.

3-7 Using ON/OFF Control

In ON/OFF control, the cont rol output t urns OFF when the t emperat ure 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 tempe rature rang e. At this time, h ow 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.

Page 64

Using ON/OFF Control Section 3-7

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.

3-8-1 AT (Auto-tuning)

• When AT is executed, the optim um PID const ants for the s et po int at that

time are set automatically. A method (called the limit cycle method) for forcibly changing the manipu lated variable and finding th e character istics 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 time” (I), and “derivative time” (D) parameters in the adjustment level.

3-8-2 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.

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 supp ly of the load connected to the control output ON simultaneously with or before starting Controller operation.

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.

1. Press the O key to move from the operation level to the adjustment level.

2. Press the U key to start execution of AT (auto-tuning). on will be displayed during AT execution.

3. off will be displayed when AT ends.

4. To return to the operation level, press the O key.

Note PID Constants

When control characteristics are already known, PID constants can be set directly to adjust control. PID constants are set in the “proportional band” (P), “integral time” (I), and “derivative time” (D) parameters in the adjustment level.

tions are met after program execution is started and the set point is changed.

At start of operation When set point is changed

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 te mpera-

ture 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 opera-

tion 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.

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.)

Note (1) The previous SRT-implemented set point is the set point that was used

for calculating the PID constants for the prev iou s 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 con stants are not changed by se lf-tuning (ST ) for the present set point.

1,2,3... 1. When the PID constants have been changed manually with ST set to ON.

2. When auto-tuning (AT) has been executed.

ST Stable Range

Operating Procedure The ST stable range determines the condition under which ST (self-tuning)

functions. This procedure sets the ST stable range to 20°C..

3-10 Using HB and HS Alarms

3-10-1 HB 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. (Heater burnout detection and HS detection cannot be used with the control output for cooling.)

Heating control output status Power to heater HB alarm output HS alarm output

Ton*3

Control output (heating)

Note (1) In the above diagram, power i s considered to be ON (normal) if the h eater

current is greater than the heater burnout detection current during the Ton interval. If the heater is burned out, the measured curr ent decreases and falls below the heater burnout detection value. The outp ut is then activated as the heater burnout alarm.

(2) In the above diagram, power is considered to be OFF (normal) if the leak-

age 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 HB and HS alarms, an OR output is established between the ALM 1 function and the HB/HS alarm. If the ALM1 function is to be used for HB 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 E5@Z power. If the heater power is turned ON after turning ON the E5 @Z power, the HB alarm will be activated.

• Control is continued even when the HB 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,” and “leakage curr en t 1 mo nitor,” parameters to check the actual current being used.

Page 74

Using HB and HS Alarms Section 3-10

• 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 once will double the detection current.

Load line

3-10-2 Installing Current Transformers (CT)

• This function can be used with E5@Z models that have the HB alarm and HS alarm. For the E5CZ, connect the CT in advance to terminals 14 and 15 (CT1). For the E5AZ/EZ, connect the CT in advance to terminals 14 and 15 (CT1). Then 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 (CT)

Single-phase Heaters For single-phase heaters, install the CT in the position shown in the following

3-10-3 Calculating Detection Current Values

• Calculate the set value using the following equation:

Heater Burnout Detection 1 set value =

HS Alarm 1 set value =

• To set the current for heater bur nout when two or more heat ers 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 cur rent, 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.

Normal current value + Burnout current value

Leakage current value (output OFF) + HS current value

Page 75

Using HB and HS Alarms Section 3-10

• 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 value monitor” and “leakage current 1 monitor” parameters.

Shifting Input Values Section 4-1

4-1 Shifting Input Values

4-1-1 Shifting Inputs

The input shift matched to the sensor currently selected in the “input type” parameter is displayed.

• A 2-point shift is applied for infrared temperature sensors. A 2-point shift can also be used if the “input shift type” parameter (advanced function setting level) is set to INS2 for a thermocouple or platinum resistance thermometer.

• There is no shift for analog inputs. Use scaling for fine adjustments.

One-point shift

• With a 1-point shift, the value set for the “temperature input shift” parameter (adjustment level) is applied to each point in the entire temperature input range. For example, if the input shift value is set to 1.2°C, the process value is treated as 201.2°C after the input shift is applied when the measured process value is 200°C.

Shifting Input Values Section 4-1

Two-point shift

• 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 thermocoup le 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.

4-1-2 How to Calculate Input Shift Values for a 2-point Shift

When an ES1B Infrared Temperature Sensor is connected to the E5CZ, 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 E5AZ only for a thermocouple/resistance thermometer Universal-input type input.)

2. Prepare a thermometer capable of measuring th e te mperatu re of the control target as shown in Figure 1 so that a 1-point shift o r 2-point shift can be carried out.

3. When ES1B is used, provide a separate power supply for the Infrared Temperature Sensors.

2. Check the control target temperature (B) and the Controller readout (A). Subtract the Controller readout temperature (A) from the control target temperature (B), and set insl and insh to the result as the input shift value. The shift is illustrated in Figure 2.

3. After setting the input shift values, check the Controller readout (A) and the control target temperature (B). If they are almost the same, this completes shifting the temperature input.

2. Use the following formulas w ith the readouts ch ecked above an d the desired temperature values to calculate th e input shift values for the upp erlimit and lower-limit temperatures of the measurement range and set the upper-limit and lower-limit temperature input shift values.

3. After setting the calculated values to insl and insh, check the Controller 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 ES1B K 140 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.

4-2-1 Standby Sequence

• T he 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 • The standby sequence is canceled when an alarm is output. It is, how-

ever, 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.

4-2-2 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, or advanced function setting level.

4-2-3 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.

4-4-1 Heating/Cooling Control

Heating/cooling control operates when h-c (heating/cooling) is selected for the “standard or heating/cooling” parameter.

The following functions are assigned to outputs in the initial status.

Note For the E5AZ/EZ, alarm 3 is assigned for control output (cooling) (alar m out-

put 2 is assigned for alarm 2).

• The heating/cooling operation of the control outputs will switch when the “direct/reverse operation” parameter is set to “direct.”

• When heating/cooling control is selected, the “dead band” and “cooling coefficient” parameters can be used.

In this manual, assigned control outputs and alarm outputs are indicated as follows: “Control output 1 must be assigned” or “Alarm 1 must be assigned.”

Page 90

Executing Heating/Cooling Control Section 4-4

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 Universal-inputs and 0.00% FS for Controllers with Analog Inputs.

Cooling Coefficient 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 outp ut assigned to the cooling side. Use this to achieve balanced control between th e 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.

When you are setting two externally input set points, set in the “number of multi-SP uses” parameter.

• Switching is possible between two set points (0 and 1) by setting the “number of multi-SP uses” parameter to 1. The default setting is 1 and does not need to be changed to switch between two set points. Set point 0 or 1 is specified by the ON/OFF state of event input 1.

4-5-2 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 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.

4-6-1 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.

4-7-1 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 after change

SP before change

Point of chan

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 set point during SP ramp 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.

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

switching from STOP to RUN mode, the process value reaches the set point using the SP ramp function in the same way as when the set point is changed. In this case, operation is carr ied out with th e proc ess valu e trea ted 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.
