“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
installation 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.

(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 tting to the rating.
• To 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 ring 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 re.
• Output relay is the part has a limited life.
When output relay contact comes to the end of its life, it might remain on-
state, or off-state. For safety, use a protective circuit outside.
1.2 Maintenance precautions
• Be sure to turn off the power before this controller is installed or removed in order to avoid an
electric shock, malfunction, and fault.

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 (sulde gas and ammonia gas, in particular) or combustible gases
are emitted.
• a place where the unit is subject directly to vibration or shock.
(vibration or shock may cause wrong action of the output relay.)
• a place exposed to water, oil, chemicals,steam and vapor.
(if immersed with water, take the inspection by sales ofce to avoid an elec-trical leakage and ring)
• 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, mag-netism, 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 t 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 im-proper tting of packings will ruin the waterproofness.)
(1) As shown in Figure 1, t a packing to the case of the unit and then insert it n the panel.
(2) Tighten screws on the xing frame or xtures 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.
• If panel strength is weak, it may cause a gap between the packing and the panel, thus impairing
water resistance.

Standard : Vertical mounting, ush on the panel. (The controller is horizontal.)
When mounting the controller on tilted surface, the maximum tilt angle is 30° (degree) from
vertical.
(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.
a = 0 to 30°

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 inuence 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 lter are recommended.
(Example: ZMB22R5-11 Noise Filter manufactured by TDK)
Make sure that the noise lter is installed to a place such as a panel that is properly grounded. The
wiring between the noise lter output terminal and theinstrument power supply terminal should be
made as short as possible. Noneof fuses or switches should be installed to the wiring on the noise
lter outputside because the lter effect will be degraded by such an 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.
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.

• The SSR/SSC-driven output, an output of 4 to 20 mA DC and retransmission are not electrically
insulated from internal circuits.
Use a non-grounded sensor for resistance bulb or thermocouple.

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
(1) Standard type (AT=1) (2) Low 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 signicant variation of PV.
In addition, the auto-tuning should not be used in any process such as pressure control and ow
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.
