1.4

Before using this product, the user is requested to read the following precautions carefully to ensure
the safety . Safety precautions must be taken by every user to prevent accidents.
The safety requirements are classified into "warning" and "caution" according to the following
interpretations :

Warning

Suggesting that the user's mishandling can
result in personal death or serious injury.

Caution

Suggesting that the user's mishandling can result
in personal injury or damage to the property.

WARNING Over-temperature Pr otection

Any control system should be designed with prior consideration that any part of the system has potential to
fail.
In case of temperature controlling, a continuance of heating on should be regarded as the most dangerous
state.
The followings are the most probable causes of inducing continuance of heating on:

1) The failure of the controller with heating output constantly on

2) The disengagement of the temperature sensor out from the system

3) The short circuit in the thermocouple wiring

4) V alve or switch contact point outside the system is locked to keep heating on

In any application in which it is apprehended that physical injury or destruction of equipment might occur,
please install an independent safeguard equipment to prevent over-temperature which shut down the heating
circuit, and for additional safety, we recommend this equipment to have its own temperature sensor.
The alarm output signal of the controller is not designed to work as protective measures when the controller
is in failure condition.

Safety PrecautionsRead before using

• If the voltage shown above exceeds 60Vdc (i.e. hazardous voltage), the basic insulation is required

between all terminals of this controller and the ground, and supplementary insulation is required for
the alarm output.
Isolation class of this controller is as shown below. Be sure to check that the isola-tion class of the
controller satisfies your requirements before installan.

• If there is a danger of a serious accident resulting from a failure or a defect in this unit, provide the unit
with an appropriate external protective circuit to prevent an accident.

• The unit is normally supplied without a power switch and fuses.
Make wiring so that the fuse is placed between the main power supply switch and this controller. (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 controller, supply the power voltage fitting to the rating.

• T o avoid an electric shock and controller 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.

2. Warning

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 50∞C 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 leakage 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 controller 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

controller and packing and between panels. Check that there are no deviation and deformation of
packing as shown in Fig.3.

Standard : Vertical mounting, flush on the panel. (The controller is horizontal.)
When mounting the controller on tilted surface, the maximum tilt angle is 30° (degree) from virtical.

(Caution)

• Don’t block the openings around the controller, or radiation effect will be reduced.

• Don’t block the ventilation openings at the top of the terminal block.

2.3 Precautions in wiring connection

• For the thermocouple sensor type, use thermocouple compensation 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: ZMB22R5-1 1 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 auxiliary 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)

• The SSR/SSC-driven output, an output of 4 to 20 mA DC, are not electrically insulate 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 controller. Use a neutral detergent
for wiping the controller.

q Standard type (AT=1)

(a) The P.I.D. parameter calculated by auto-tuning remains even if the power is turned off. If the power is

turned off before the auto-tuning is completed, you must restart the auto-tuning.

(b) The PV may be changed greatly depending on the process, because the con trol output is ON/OFF action

(two position operation) in the auto-tuning. So, do not use the auto-turning if the process does not allow a
significant variation of PV.
In addition, the auto-tuning should not be used in any process such as pressure control and flow control,
where a quick-response is required.

(c) If the auto-tuning isn’t completed in four hours, the auto-tuning is suspected to fail. In this case, check the

wiring and parameters such as the control action,
input type, etc.

(d) Carry out the auto-tuning again, if there is any change in SV, input range (P-SL, P-SV or P-dP) or process

condition. Perform the auto-tuning if fuzzy control is selected as the control algorithm.

(e) When resetting the AT parameter , set the parameter to “0” once, then reset it.

6-2 Auto-tuning (AT)

Autotuning is the automatic calculation and entering of the control parameters (P,I and D) into memory. Prior
to the auto-tuning, complete the setting of input range
(P-SL,P-SU, P-dP), a set value (SV), alarm setting (AL1, AL2), and cycle time (TC).

Set the parameter AT as either “1” or “2” by using or key, and press the

SEL

key to start the auto-turning.
Then the point indicator at the lower right starts blinking. At the completion of Auto-tuning, the point indicator
stops blinking, then parameter AT is automatically set to 0.

How to start the auto-tuning

w Low PV type (AT=2) :

Overshoot decreased
at tuning.

– 17 –

1) At power on, changing a set value or the external disturbance, tuning is made automatically so that the PID
parameters are re-optimized.
It is useful where modification of PID parameters is required repeatably due to frequent change in process
condition.
If high controllability is important, select the PID or fuzzy control algorithm and use auto-tuning.

2) Setting for self-tuning

q Turn on the power and set the SV.
w Select SELF at “CTrL” (control algorithm) parameter.
e Turn off the power once.
r Turn on the power of the whole system. The controller should be turned on at the same time with the

other equipments or even later. Otherwise, the selftuning might not be performed successfully.

t Self-tuning starts. Then the point indicator at the lower right corner starts blinking until the PID parameters

are re-optimized.

Note) Whenever it is necessary to re-try the self-tuning, please set “CTrL” = PID

once, and then start the above setting procedure from the beginning.

4) Self-tuning is executed by any of the following conditions.

q During temperature rise at power ON.
w During temperature rise at SV changing if necessary.
e When control is out of stable condition and is judged as being out of stable condition continuously.

5) Self-tuning is not executed under the following conditions:

q During standby mode
w During ON/OFF control
e During auto-tuning
r During ramp/soak operation
t During input error
y With dual output (“P-n1” ≥ 4)
u When P, I, D or Ar is manually set

Under the following coditions, self-tuning is canceled.

q When SV is changed.
w When Self-Tuning can not be completed in about 9 hours after the start.

6) Cautions

· Turn on the power of the whole system. The controller should be turned on at the same time with the
other equipments or even later. Otherwise, the self tuning might not be performed successfully.

· Don’t change the SV while the self-tuning is executing.

· Once PID parameters are optimized, the self-tuning is not excuted at the next power on unless SV is

changed.

· After the execution of self-tuning, if the controlability is not your expected level, please select PID or
FUZZY at “CTrL” parameter, and then, start the auto-tuning.

Note 1) Except for the following, the input accuracy is ±0.5% FS ±1 digit ±1°C

(Input accuracy does not be guaranteed for the ranges of measurement
other than in the table above.)

Note 2) In case a measuring range of -150 to 600

°

C or -150 to 850°C is used for

resistance bulb input, temperatures below -150

°

C does not be indicated
correctly. Therefore, “LLLL” does not appear despite a continuous fall
below -150

°

C.

Note 3) If the resistance bulb or thermocouple is used at a temperature below

the lowest value in the measurement range, the input accuracy cannot
be guaranteed.

Note 4) Addition of decimal point is impossible if the input range or span is larger

than 999.9 at the RTD/thermocouple input.

in these ranges, this controller may
display an incorrect process value
due to the characteristic of the sensor.

Note) · When alarm action type code is changed, alarm set value may also become different from previous

settings.
Please check these parameters, turn off the power once, and then re-start the controller, before s
tarting control.

· When selecting No.12 to 15, setting in ALM2, dLY2, and A2hy are effective, and output to the AL2
