Safety Precautions
Warning
The FP23 Series Digital Controller is control instruments designed for industrial use to control
temperature, humidity and other physical quantities in general industrial facilities. It must not be used
in any way that may adversely affect the safety, health or working conditions of those who come into
contact with the effects of its use. When used, adequate and effective safety countermeasures must
be provided at all times by the user. No warranty, express or implied, is valid when this device is
used without the proper safety countermeasures.
Before you start to use this device, install it in a control panel or the like and avoid touching the
terminals.
Do not open this device's case, and touch the boards or inside of the case with your hands or a
conductor. The user should never repair or modify this device. Doing so might cause an
accident that may result in death or serious bodily injury from electric shock.
Caution
To avoid damage to connected peripheral devices, facilities or the product itself due to malfunction of
this device, safety countermeasures such as proper installation of the fuse or installation of
overheating protection must be taken before use. No warranty, express or implied, is valid in the
case of use resulting in an accident without having taken the proper safety countermeasures.
The warning mark on the plate affixed on the casing of this device warns you not to touch
charged parts while this device is powered ON. Doing so might cause an electric shock.
A means for turning the power OFF such as switch or a breaker must be installed on the
external power circuit connected to the power terminal on this device. Fasten the switch or
breaker at a position where it can be easily operated by the operator, and indicate that it is a
means for powering this device OFF.
This device does not have a built-in fuse. Install a fuse that conforms to the following rating in
the power circuit connected to the power terminal.
Fuse rating/characteristics: 250 VAC 1.0A/medium lagged or lagged type
When wiring this device, tighten the terminal connections firmly.
Use the device with the power voltage and frequency within their rated ranges.
Do not apply a voltage or current outside of the input rating to the input terminal. Doing so
might shorten the service life of this device or cause it to malfunction.
The voltage and current of the load connected to the output terminal should be within the
rated range. Exceeding this range may cause the temperature to rise which might shorten the
service life of this device or cause it to malfunction.
This device is provided with ventilation holes for heat to escape. Prevent metal objects or
other foreign matter from entering these ventilation holes as this may cause this device to
malfunction. Do not block these ventilation holes or allow dirt and dust to stick to these holes.
Temperature buildup or insulation failure might shorten the service life of this device or cause
it to malfunction.
Repeated tolerance tests on voltage, noise, surge, etc. may cause this device to deteriorate.
Never remodel this device or use it a prohibited manner.
To ensure safe and proper use of this device, and to maintain its reliability, observe the
precautions described in this manual.
Do not operate the keys on the front panel of this device with a hard or sharp-tipped object. Be
sure to operate the keys with your fingertips.
When cleaning this device, do not use paint thinner or other solvents. Wipe gently with a soft,
dry cloth.
It takes 30 minutes to display the correct temperature after applying power to the digital controller.
(Therefore, turn the power on more than 30 minutes prior to the operation.)

Precautions for Installation Site
Caution
Do not use this device in the following sites. Doing so might result in malfunction or damage to
this device and in some cases cause fire and/or dangerous situations.
Locations that are filled with or generate inflammable gas, corrosive gas, dirt and dust,
smoke, etc.
Locations that are subject to water droplets, direct sunlight or strong radiated heat from
other equipment
Locations where the ambient temperature falls below -10°C or rises above 50°C
Locations where dew condensation forms and the humidity reaches 90% or more
Near equipment that generates high-frequency noise
Near heavy current circuits or locations likely to be subject to inductive interference
Locations subject to strong vibration and impact
Locations exceeding an elevation of 2000 m

Precautions for Wiring
Caution
To prevent electric shock, always turn off and disconnect this device from the power supply
before starting wiring.
Do not touch wired terminals or charged parts with your hands while the power is supplied.
Pay attention to the following points when performing wiring:
Check that the wiring is free from mistakes according to "
Rear Terminal Arrangement
Diagram."
Use crimped terminals that accommodate an M3 screw and that have a width of 6.2 mm or
less.
For thermocouple input, use a compensation wire compatible with the type of thermocouple.
For RTD input, the resistance of a single lead wire must be 10
ȍ
or less and the three wires
must have the same resistance.
The input signal lead must not be passed along the same conduit or duct as that for
high-voltage power lines.
Shield wiring (single point grounding) is effective against static induction noise.
Short interval twisted pair wiring is effective against electromagnetic induction noise.
When wiring, use wire or cable (minimum 1 mm
2
cross-sectional area) of 600 V grade PVC
insulated wire or equivalent wire having the same rating.
For wiring the ground, ground the ground terminal with the earth resistance at less than
100
ȍ
and with wire 2 mm
2
or thicker.
Two earth terminals are provided, each connected internally. One is for the ground
connection, and the other is for connecting the shield of the signal lead. Do not use the
earth terminals for crossover wiring of the power system ground lead.
If this device is considered as being susceptible to noise caused by the power supply,
attach a noise filter to prevent abnormal functioning.
Install a noise filter onto a grounded panel, and make the wire connecting the noise filter
output and the power supply terminal on this controller as short as possible.
