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.

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.

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.
