Caution
This instrument is intended to be used under the following environmental
conditions (IEC61010-1): Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:
• A minimum of dust, and an absence of corrosive gases
• No flammable, explosive gases
• No mechanical vibrations or shocks
• No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to 122 )
that does not change rapidly, and no icing
• An ambient non-condensing humidity of 35 to 85%RH
• No large capacity electromagnetic switches or cables through which large current is
flowing
• No water, oil or chemicals or where the vapors of these substances can come into
direct contact with the unit
• Take note that ambient temperature of this unit - not the ambient temperature of the
control panel - must not exceed 50 (122 ) if mounted through the face of a control
panel. Otherwise the life of electronic components (especially electrolytic capacitor)
may be shortened.
Note: Avoid setting this instrument directly on or near flammable material even
though the case of this instrument is made of flame-resistant resin.

Caution
• Do not leave wire remnants in the instrument, as they could cause a fire and/or malfunction.
• Use the solderless terminal with an insulation sleeve in which an M3 screw fits when
wiring the FCS-23A.
• The terminal block of this instrument is designed to be wired from the left side.
The lead wire must be inserted from the left side of the terminal, and fastened with the
terminal screw.
• Tighten the terminal screw within the specified torque. If excessive force is applied to
the screw when tightening, the screw or case may be damaged.
• Do not apply a commercial power source to the sensor connected to the input terminal
nor allow the power source to come into contact with the sensor, as the input circuit
may be burnt out.
• This controller has no built-in power switch, circuit breaker or fuse. It is necessary to
install them near the controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)
• For a 24V AC/DC power source, do not confuse polarity when using direct current (DC).

Caution
• It is recommended that AT (auto-tuning) be performed during the trial run.
• Do not touch live terminals. This may cause electric shock or problems in operation.
• Turn the power supply to the instrument OFF when retightening the terminal and
cleaning. Working on or touching the terminal with the power switched ON may result
in severe injury or death due to electric shock.
• Use a soft, dry cloth when cleaning the instrument.
(Alcohol based substances may tarnish or deface the unit.)
• As the display section is vulnerable, do not strike or scratch it with a hard object or
press hard on it.
5
Caution
• Setup by the DIP switch and Rotary switch inside of the controller is required
before the power is turned on.
• Default values of the FCS-23A:
Sensor input: K
Control action: Fuzzy self-tuning PID, Heating control action

4. Mounting to the Control Panel
4.1 Site Selection
This instrument is intended to be used under the following conditions
(IEC61010-1): Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:
(1) A minimum of dust, and an absence of corrosive gases
(2) No flammable, explosive gases
(3) No mechanical vibrations or shocks
(4) No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to 122 )
that does not change rapidly, and no icing
(5) An ambient non-condensing humidity of 35 to 85%RH
(6) No large capacity electromagnetic switches or cables through which large current flows
(7) No water, oil or chemicals or where the vapors of these substances can come into
direct contact with the unit
(8) Take note that ambient temperature of this unit - not the ambient temperature of the
control panel - must not exceed 50 (122 ) if mounted through the face of a control
panel. Otherwise the life of electronic components (especially electrolytic capacitor)
may be shortened.

Caution
As the case is made of resin, do not use excessive force while screwing in the
mounting bracket.
The torque should be 0.12N•m.
• When using the One-touch type mounting bracket
Mounting panel thickness: 1 to 3mm.
Mount one-touch mounting brackets
1
1
to the instrument first, then insert the
FCS-23A
2
from the front of the
panel.
If Soft front cover (FC-48-S) is used, 2
the mounting panel thickness will be
1 to 2.5mm.
1
(Fig. 4.4-1)
• When using the Screw type mounting bracket (Option code: BL)
Mounting panel thickness: 1 to 8mm
If Soft front cover (FC-48-S) is used, mounting panel thickness will be 1 to 7.5mm.
Insert the FCS-23A from the front of the panel.
Attach the mounting brackets to the slots at the top and bottom of the case,
and secure the controller in place with the screws provided.
(Fig. 4.4-2)

5. Wiring
Warning
Turn the power supply to the instrument off before wiring or checking.
Working on or touching the terminal with the power switched on may result in
severe injury or death due to electric shock.
Moreover, the instrument must be grounded before the power supply to the
instrument is turned on.
Caution
• The terminal block of this instrument is designed to be wired from the left side.
The lead wire must be inserted from the left side of the terminal, and fastened by the
terminal screw.
• Use a thermocouple and compensating lead wire according to the sensor input
specifications of this controller.
• Use a 3-wire RTD system according to the sensor input specifications of this controller.
• This controller does not have a built-in power switch, circuit breaker or fuse.
Therefore, it is necessary to install them in a circuit externally, near the controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)
• For a 24V AC/DC power source, do not confuse polarity when using direct current (DC).
• When using a relay contact output type, externally use a relay according to the
capacity of the load to protect the built-in relay contact.
• When wiring, keep the input wires (thermocouple, RTD, etc.) away from AC sources
or load wires.
• Use a thick wire (1.25 to 2.0mm
2
) for grounding.
Lead wire solderless terminal
Use a solderless terminal with an insulation sleeve in which an M3 screw fits as shown
below.
The torque should be 0.63N•m.
