Safety Precautions
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
Caution
WARNING
“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.
Suggesting that the user's mishandling can
result in personal death or serious injury.
Suggesting that the user's mishandling can result

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 5°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.
(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 office to avoid an electrical leakage and firing )
•A place where the unit is exposed to dust, salty air, or air containing iron particles.
•A place where the unit is subject to interference with static electricity, magnetism, and noise.
•A place where the unit is exposed to direct sunshine.
•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 excessiv ely be cause the mounting brac ket can be remo v ed from the stopper b y the f orce.)
• 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.
• If panel strength is weak, it may cause 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 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 po w er supply, the additional installation of an insulating transf ormer
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.
•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 b y Fuji Electric to protect a contact from switching surge 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.

Z-Trap connection
• The SSR/SSC-driven output, output of 4 to 20 mA DC, and retansmission are 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 controller. Use a neutral detergent for wiping the controller.
