(main power supply: 2 pole breaker, fuse rating: 250V, 1A)

• When wiring the power supply terminal, use vinyl insulated 600 volt cable or equivalent.

• To avoid the damage and failure of equipment, supply the power voltage fitting to the rating.

• To avoid an electric shock and equipment failure, do not turn ON the power before all wiring is completed.

• Be sure to check that the distance is kept to avoid electric shock or firing before turning the power ON.

• Keep away from terminals while the circuit is energized in order to avoid an electric shock and a malfunction.

• Never attempt to disassemble, fabricate, modify, or repair this unit because tampering with the unit may result in a malfunction, electric shock, or a fire.

1.2 Maintenance precautions

• Be sure to turn off the power before this unit is installed or removed in order to avoid an electric shock, malfunction, and fault.

• Regular maintenance is recommended a longer service life of this unit. Some parts of this unit have a limited life span, or they will be deteriorated with the lapse of time.

• One-year warranty is guaranteed for this unit including accessories, provided that the unit is properly used.

Caution

2.1 Cautions on installation

Avoid the following places for installation.

• a place where the ambient temperature may reach beyond the range of from 0 to 50Åé while in operation.

• a place where the ambient humidity may reach beyond the range of from 45 to 85% RH while in operation.

• a place where a change in the ambient temperature is so rapid as to cause condensation.

• a place where corrosive gases (sulfide gas and ammonia gas, in particular) or combustible gases are emitted.

• a place where the unit is subject directly to vibration or shock.

• a place exposed to water oil, chemicals,steam and vapor.

(if immersed with water, take the inspection by sales office to avoid an electrical and firing )

• a place where the unit is exposed to dust, salt air, or air containing iron particles.

• a place where the unit is subject to intereference with static electricity, magnetism, and noise.

• a place where the unit is exposed to direct sunlight.

• a place where the heat may be accumulated due to the radiation of heat.

2.2 Caution on installation on panel

• Insert the mounting bracket (accessory) from the rear side until the main unit is securely fit into the panel. If there should be a play, tighten two screws lightly until the play is eliminated. (Do not tighten the screws excessively because the mounting bracket can be removed from the stopper by the force.)

• The front side of this instrument conforms to NEMA 4X(equivalent with IP66). To ensure the waterproofness between the instrument and the panel, use packings that are provided as accessories in the following manner: (The improper fitting of packings will ruin the waterproofness.) q

As shown in Figure 1, fit a packing to the case of the unit and then insert it in the panel.

w

Tighten screws on the fixing frame or fixtures so that no gaps are given between the front of equipment and packing and between panels. Check that there are no deviation and deformation of packing as shown in Fig.3.

2.3 Precautions in wiring connection

• For the thermocouple sensor type, use thermocouple extension wires for wiring.

For the RTD type, use a wiring material with a small lead wire resistance and no resistance differentials among three wires.

• Keep input lines away from power line and load line to avoid the influence from noise induced.

• For the input and output signal lines, be sure to use shielded wires and keep them away from each other.

• If a noise level is excessive in the power supply, the additional installation of an insulating transformer and the use of a noise filter are recommended. (example: ZMB22R5-11 Noise Filter manufactured by

TDK)

Make sure that the noise filter is installed to a place such as a panel that is properly grounded. The wiring between the noise filter output terminal and the instrument power supply terminal should be made as short as possible. None of fuses or switches should be installed to the wiring on the noise filter output side because the filter effect will be degraded by such a installation.

• A better anti-noise effect can be expected by using stranded power supply cable for the instrument.

(The shorter the stranding pitch is, the better the anti-noise effect can be expected.)

• For the unit with an alarm against a failure (burn-out) in the heater, use the same power line for connection of the power supplies for the heater and the controller.

• A setup time is required for the contact output when the power is turned on. If the contact output is used as a signal for an external interlock circuit, use a delay relay at the same time.

• Use the supplemental relay since the life is shortened if full capacity load is connected to the output relay. SSR/SSC drive output type is preferred if the output operations occur frequently.

[Proportional interval] relay output: 30 seconds or more, SSR/SSC: one second or more

• If inductive load such as magnetic switches connected as a relay output load, it is recommended to use Z-Trap manufactured by Fuji Electric to protect a contact from switching serge and keep a longer life.

Model : ENC241D-05A (power supply voltage: 100 V)

ENC471D-05A (power supply voltage: 200 V)

Where to install : Connect it between contacts of the relay control output.

Example) PXV4

For TP48X

6 5 4 3

• The SSR/SSC-driven output, an output of 4 to 20 mA DC, is not electrically insulated from internal circuits.

Use a non-grounded sensor for resistance bulb or thermocouple.

2.4 Requirement for key operation/operation in abnormalities

• Prior to the operation, be sure to check alarm functions, since a failure in the proper setting will result in a failure in the proper output of an alarm in case of an abnormality.

• A display of UUUU or LLLL will appear in case of a break in the input. Be sure to turn off the power when a sensor is replaced.

2.5 Others

• Do not use organic solvents such as alcohol and benzine to wipe this unit. Use a neutral detergent for wiping the unit.

Setting the input

* Skip this procedure if specified when you order.

q

Is the input sensor type same as what you use ?

Select the sensor you use from those in Table 1, and set it in the parameter P-n2.

(Example) For T thermo-couple, set P-n2 to "7".

(Note) Changing between resistance bulb and the rmo-couple is allowed, though that between 1 to 5

VDC (4 to 20mA DC) and thermo-couple/resis tance bulb is not allowed.

w

Is setting of input temperature range suitable for the

sensor you use?

Standard range to each sensor is shown in Table 2. Select the temperature range suitable for the equipment you use, set lower/upper limit values to P-SL/P-SU respectively.

(Example) Temperature range 0 to 800 [

°

C] set P-SL and

P-SU to 0 and 800 respectively.

(Note) Standard range is recommended to set though

(Note) other setting is available.

No standard range is given if 1 to 5VDC(4 to

20mA DC) are input.

Description

Output takes ether

ON (100%) or OFF

(0%).

(Suitable when frequent output switching is inconvenient.)

PID control

Fuzzy control

Output is calculated with PID parameters, outputting 0 to 100% with setting proportional period

(TC) as 100%.

Control with less overshoot is available.

Fuzzy operation is added to PID providing control with less overshoot.

Method

Parameter P is set to

0.0.

*Refer to “5-1 ON/OFF control”

Perform the auto-tuning to automatically calculate an optimal PID

(manual operation is also available).

*Refer to “5-2 Autotuning”.

Set the parameter

FUZY to ON.

Perform the auto-tuning

(same as PID control).

5-2 Auto-tuning (AT)

The auto-tuning is automatic measurement, computation, and setting of the P.I.D. constant that are performed by the micro-controller. Prior to the auto-tuning, complete the setting of input range (P-SL, P-SU,

P-dP), a set value (SV), alarm setting (H,L), and proportional time cycle (TC).

How to start the auto-tuning

Set the parameter, AT to either “1” or “2” by using or key. The auto-tuning starts automatically after 3 seconds. Then the point indicator at the lower right will start blinking. When auto-tuning ends, parameter AT is automatically set to 0 after flashing at decimal point of digit 1 disappears.

(a) The P.I.D. parameter calculated by auto-tuning, will be retained even if the power is turned off. If, however, the power is turned off in the auto-tuning, you must restart the auto-tuning.

(b) The PV may be changed greatly depending on the process, because the control output is ON/OFF action in the auto-tuning. So, do not use the auto-turning if the process does not allow a significant variation of

PV.

Also, the auto-tuning should not be used in a quick-responsive process such as pressure control and flow control.

(c) If the auto-tuning fails to complete in four hours, an abnormality in the auto-tuning may be suspected. In this case, recheck the wiring, control output operations (nomal and reverse action), and parameters such as the input sensor type.

(d) Carry out the auto-tuning again when the SV is significantly changed, parameter P-SL, P-SU or P-dP is changed or a controlled equipment operation is changed.

(e) Figures q

and w

show the behavior of PV during the auto-tuning.

(f) Perform the auto-tuning also when fuzzy control is selected in the control type setting.

Auto-tuning (Setting range: 0, 1, 2)

[Description]

• PID value can be set automaticaly.

• Once PID value is set automatically by auto-tuning, it is saved in the controller even when the power is turned OFF, so auto-tuning function is not required any further.

• Auto-tuning is started by setting 1 or 2 in AT parameter. AT value is automatically reset to 0 at the end of auto-tuning.

• AT the end of auto-tuning, control action is started automatically by setting PID.

• During auto-tuning, the decimal point at 1 digit of SV display flickers.

• When auto-tuning is forcedly suspended, set AT value to 0 or turn

OFF the instrument power.

During auto-turning, ON-OFF control is performed which causes overshoot for SV. But, the overshoot can be eliminated by low PV type auto-tuning.

• Auto-tuning is available just after the start of operation or in the stare of stable control.

• When dual output type is used, autotuning is effected only on the heating control side. At this time, the cooling side output is OFF. The cooling side proportional band can be set manually by the parameter COOL.

[Description]

• Proportional band can be set automatically by auto-tuning.

• Manual setting is also possible. If

P value is too small, control action becomes unstable, and if it is too large, the response becomes slow.

• When P is set to 0.0, 2-position action becomes effective.

The hysteresis under 2-position action should be set with the parameter HYS.

• When dual output type is used and it is set to P = 0.0 and COOL = 0.0, the heating and cooling outputs are as shown in the following diagram.

In this case, the hysteresis is fixed at 0.5%.

Setting of proportional cycle of control output 1

(Setting range 1 to 150 sec.)

[Description]

• When contact output or SSR drive output type is used, the output turns

ON/OFF at a contact cycle when the input is within the proportional band.

This cycle is called the proportional cycle. The output value is expressed by the ratio which the output turns

ON within the time of proportional cycle.

As the time of proportional cycle becomes short, control can be made more accurately, but it reduces the life of operation terminal unit, so it needs to be set in consideration of the life of operation terminal unit.

In this case of current output, this parameter is not displayed.

[Description]

• Hysteresis width under the 2-position action control can be set as shown in the example. When hysteresis width is set small, the control efficiency is improved, but the number of operations increases and decreases the life of the operation terminal unit and the device.

• Hysteresis width is necessary to prevent chattering due to noise.

• For 2-position action, the value of

P (proportional band) should be set to 0.0.

• Set value can be obtained by industrial value.

Cooling side proportional cycle of control output 2

(DUAL type only) (Setting range: 1 to 150 sec.)

[Description]

• This setting is required only for

• When contact output or SSR drive output type is used, the output turns

ON/OFF at a constant cycle when the input is within the proportional band.

This cycle is called the proportional cycle.

The output value is expressed by the ratio of which the output turns ON within the time of proportional cycle.

As the time of proportional cycle becomes short, control can be made more accurately, but it reduces the life of operation terminal unit, so it needs to be set in consideration of the life of operation terminal unit.
