Non-insulation
• 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 equipment.
(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
65 43
• 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.

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

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.

Heater burnout alarm (option) (Setting range: 1.0 to 50.0A)
[Description]
• Burnout detect current (parameter
Hb) should be set according to the
type of heater being used.
It is set to 0.0 prior to delivery from
the factory.
• Alarm operating point is set by parameter Hb.
• Current detector (CT) comes in 2
types, 0 to 30A type (CTL-6-SF) and
20 to 50A type (CTL-12-S36-8F).
It should be selected according to the
heater power source being used.
• Setting of alarm operating point
. Apply current to the heater with the
controller output turned ON.
. Search alarm operating value while
changing the set value of Hb )when
changing the set value, the next set
value should be changed more than
3 seconds later).
. After operating point is obtained,
use 70 to 80% of the value as the
final set value.
. When N number of heaters are used,
set it in the middle between the current at N number of heaters and that
of N-1 number.
• When detection error is large due to
small heater capacity, increase the
apparent current 2 times larger by
putting the wire twice through the
hole to improve the sensitivity of the
detector (in this case, set the current
to a two-fold value).
• When wire through CT is wound
many turns, be sure to wind it from
the same direction.
• The heater burnout alarm function
can not be used in case when the
heater is controlled by thyristor phase
angle control system.
• When 3-phase heater is used, heater
burnout can be detected in some
cases. For details, contact our office.

[Description]
Example) Altering proportional band 10.0% to 15.0%
• 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.
The following shows the standard
proportional cycle.

2-position action hysteresis width (Setting range: 0.0
to 50.0%FS)
Example) Altering the hysteresis width of 1°C to 2°C
[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
DUAL type.
• 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.

Lower limit of measurement range and set value (SV)
(Setting range: -1999 to 9999)
Upper limit of measurement range and set value (SV)
(Setting range: -1999 to 9999)
[Description]
• Lower limit (minimum range) and
upper limit (maximum range) of
measurement ranges can be set.
This setting is used as a limiter of
set value (SV). Change of set value
(SV) to others outside of the lower/
upper limit range is not possible.
• When 1 digit below the decimal
point needs to be displayed, it
should be set to 1 by P-dP.
• When P-n2 is set to 0 to 13 (temperature input), up to 1 digit (P-dP
parameter = 1) below the decimal
point becomes effective.
• For the input range, refer to the following table.

Setting of lower limit alarm (ALM2) action type (option)
Setting of upper limit alarm (ALM1) action type (option)
[Description]
Absolute value alarm
Lower limit hold
• Alarm action can be selected from
16 types. Of these types, deviation
alarm, absolute value alarm, range
alarm and hold (lower limit) are
explained in the following. Alarm
is specified by either one of deviation and absolute value.
When alarm is outputted at temperature of more than 200°C and less than
50°C the setting of upper limit alarm
(AH) is 200°C and that of lower limit
alarm (AL) is 50°C. Unlike the deviation alarm, the alarm action point
remains unchanged at change of the
set value.
At the start of operation, the furnace
temperature is normally below 100°C.
In this case, lower limit alarm is not
outputted. When temperature rises
above the set value of AL and then
lowers, lower limit alarm turns ON.
This function is called the alarm action “Hold”.
Deviation alarm
ON
When alarm is outputted at temperature of more than 100°C above 100°C
of set value (SV) and more than 50°C
below the set value, the setting of
upper limit alarm (AH) is 100°C and
that of lower limit alarm (AL) is 50°C.
When the set value (SV) changes, the
alarm action point is also changed.

• This function is used to select or not
to select FUZY control.
• FUZY control provides the following advantages.
. Quick start without causing overshoot.
. Quick settlement in response to
external disturbance.
• Use this function after setting P.I.D
parameter to optimum value, using
auto-tuning, etc.
Example) Set FUZY control to ON.

User’s adjust zero adjustment (Setting range: -50 to 50%FS)
User’s adjust span adjustment (Setting range: -50 to 50%FS)
[Description]
• This function is used to calibrate
input by user.
• Using zero input or span input, error is set in the input range.
• User calibration function is independent of adjustment of the controller.
By setting 0 in this parameter, it can
casily be set back to the state prior
to delivery from the factory.
• It is used to set the same reading
between controllers or between controller and recorder.
Example)
When the input range is 0 to 400°C,
the reading at 0°C input is -1°C and
that at 400°C is 402°C.
In this case, when ADJO parameter is set to 1 and ADJS to -2, the
reading at 0°C input becomes 0°C
and that at 400°C input becomes
400°C.
When both ADJO and ADJS are
set to 0, the controller is set in the
calibrated state prior to delivery
from the factory.

Setting of ramp/soak control (ProG) (option) (roff/rrUn/rHLd)
[Description]
• This function is used to change time
and set value (SV) automatically
according to preset pattern. Up to
4 ramp/soak programs can be used.
• The No. 1 ramp starts from measurement value (PV) just before the
execution of program.
• It is also possible to run the program
automatically at power ON (power
ON start function).
Example) Start ramp/soak operation (rrUn) from local operation (roFF)
