“Any control system design should take into account that any part of the system has the potential to fail”.
“For temperature control systems, continued heating should be considered the most dangerous condition,
and the machine should be designed to automatically stop heating if unregulated due to the failure of the
control unit or for any other reason”.
The following are the most likely causes of unwanted continued heating:
1) Controller failure with heating output constantly on
2) Disengagement of the temperature sensor from the system
3) A short circuit in the thermocouple wiring
4) A valve or switch contact point outside the system is locked to keep the heat switched on.
In any application where physical injury or destruction of equipment might occur, we recommend the instal-
lation of independent safety equipment, with a separate temperature sensor, to disable the heating circuit in
case of overheating.
The controller alarm signal is not designed to function as a protective measure in case of controller failure.

2. Caution
2.1 Cautions on installation
Avoid the following places for installation.
•aplace where the ambient temperature may reach beyond the range of from 0 to 50°C while in
operation.
•aplace where the ambient humidity may reach beyond the range of from 45 to 85% RH while in
operation.
•aplace where a change in the ambient temperature is so rapid as to cause condensation.
•aplace where corrosive gases (sulfide gas and ammonia gas, in particular) or combustible gases are
emitted.
•aplace where the unit is subject directly to vibration or shock.
(Vibration or shock may cause output relay malfunction.)
•aplace 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)
•aplace where the unit is exposed to dust, salt air, or air containing iron particles.
•aplace where the unit is subject to intereference with static electricity, magnetism, and noise.
•aplace where the unit is exposed to direct sunlight.
•aplace 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 be cause 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 water-
proofness 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.)
qAs shown in Figure 1, fit a packing to the case of the unit and then insert it in the panel.
wTighten screws on the fixing frame or fixtures so that no gaps are given between the front of control-
ler and packing and between panels. Check that there are no deviation and deformation of packing as
shown in Fig.3.
•If panel strength is weak, it may causes a gap between the packing and the panel, thus impairing
water resistance.

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 differen-
tials 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 an installation.
•Abetter 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.
•Asetup 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: 100V)
ENC471D-05A (power supply voltage: 200 V)
Where to install : Connect it between contacts of the relay control output.
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.
•Adisplay 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 deter-
gent for wiping the controller.

Cautions on wiring •Wiring should be started from the left side terminal (No. 1 to No.6).
•Use crimped terminals matched to the screw size. Tightening torque should be about
0.8 N·m (Since the case is made of plastic, do not tighten excessively).
•Do not connect anything to terminals not used.
Note 1
Caution on side by side installation
• With the power supply of 200VAC or more, a maximum ambient temperature is 45˚C.
(It is recommended to use a fan for cooling.)
When there is another instrument (larger than 70mm) or a wall on the right side of this controller, be
sure to install the controller keeping a space of more than 30mm.
Wateproofness cannot be ensured in the case of side-by-side installation.

6-2 Auto-tuning (AT)
Auto-tuning 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
q Standard type (AT=1) wLow PV type (AT=2) : Overshoot decreased
at tuning.
(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 control 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)While carring out auto-tuning, PV operates as shown in Figs 1 and 2.
(f) Execute the auto-tuning also when fuzzy control is selected in control type setting.
(g)When resetting the AT parameter, set the parameter to “0” once, then reset it.

6-3 Self-tuning
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
qTurn on the power and set the SV.
wSelect SELF at “CTrL” (control algorithm) parameter.
eTurn off the power once.
rTurn 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.
tSelf-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.
