To prevent accidents arising from the misuse of this indicator, please ensure the operator receives thismanual.

Warning
Turn the power supply to the instrument OFF before wiring or checking.
Working or touching the terminal with the power switched ON may result in severe injury
or death due to Electric Shock.

Caution
Do not apply a commercial power surce to the sensor connected to the input terminal
nor allow the power source to come into contact with the sensor.

After setup is completed, insert the internal assembly into the case.
(Do not confuse the top and bottom of the inner assembly. If inserting the assembly into the case in thewrong direction, the PCB may be damaged.)
Surely insert the assembly until it is locked by the hook at the right of the instrument. (“Click” sounds)

4.1 Site selection
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• Few 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 flows• No water, oil or chemicals or where the vapors of these substances can come into direct contact
with the FIR-201-M• If the FIR-201-M is installed through the control panel, the ambient temperature of the unit must be kept
to under 50 . Otherwise the life of electronic parts (especially electrolytic capacitors) of the unit will be
shortened.

Mounting panel thickness: 1 to 3mm
First, mount One-touch type mounting
brackets 1 to the body, and then insert
the unit 2 from the panel front.
When using Soft front cover (FC-R), thepanel thickness for mounting will be 1 to 2.5mm.

NoticeAs the case is made of resin, do not use excessive force while screwing in the mounting
bracket. The torque should be approximately 0.12N･m.

5. Terminal arrangement
Warning
Turn the power supply to the instrument OFF before wiring or checking.
Working 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 supplied to the instrument
is turned on.

Notice• Use a thermocouple and compensation lead wire corresponding to the input specificationsof this indicator.
• Use a 3-wire RTD which corresponds to the input specification of this indicator.
• This indicator does not have a built-in power switch or fuse. Therefore, it is necessary to
install them in the circuit near the external indicator.
• In the case of 24V DC, do not confuse the polarity.
• 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 (TC, RTD, etc.) away from AC sources and load wires toavoid external interference.
• Use a thick wire (1.25 to 2.0mm2) for grounding.

Sensor correction
This corrects the input value from the sensor. When a sensor cannot be set at the exact location
where measurement is desired, the sensor measured temperature may deviate from the temperaturein the measured location.
When measuring with plural FIR-201-M units, sometimes the measured temperatures (input value) do notconcur due to differences in sensor accuracy or dispersion of load capacities. In such a case, themeasurement can be set at the desired temperature by adjusting the input value of sensors.

Alarm action Energized/De-energized
If an alarm action Energized is selected, the alarm output (between terminals 5-6, 7-8 or 9-10) is
conducted (ON) while the alarm action indicator is being lit, and it is not conducted (OFF) while the alarm
action indicator is being unlit.
If an alarm action De-energized is selected, the alarm output (between terminals 5-6, 7-8 or 9-10) is notconducted (OFF) while the alarm action indicator is being lit, and it is conducted (ON) while the alarm
action indicator is being unlit.

7. Operation
After the FIR-201-M has been mounted to the control panel and wiring is completed, operate the unit
following the procedures below.
(1) Turn the power supply to the FIR-201-M ON.
For approximately 2 seconds after the power is turned on, the sensor type and temperature unit are
indicated on the PV display and input range high limit value is indicated on the SV display. See (Table 6-1).
During this time, all outputs and LED indicators are in OFF status.
After that, actual temperature is indicated on the PV display, and alarm value is indicated on the SV display.
(2) Input each set value.
Input each set value, referring to Chapter “6. Operation flowchart”.
[HOLD function usage]
To use the Hold function, connect terminals 15 and 16.
Select a Hold type with the switch (SW304).
Hold: The PV at the given time is held and indicated.
Peak hold : The updated maximum PV is indicated.
Bottom hold : The updated minimum PV is indicated.

For approximately 2 seconds after the power supply to the instrument is turned on, the input type
and temperature unit are indicated on the PV display and input range high limit value (for DC input,
scaling high limit value) is indicated on the SV display.

11 Troubleshooting
When any malfunction occurs, refer to the following items after checking the power supply and thewiring.

Warning
Turn the power supply to the instrument OFF before wiring or checking.
Working or touching the terminal with the power switched ON may result in severe injury or
death due to Electric Shock.

Problem[] is flashing on the PV display.

[] is flashing on the PV display.

The value on the PV display does notchange.
The alarm action indicator does not light.
The SV display does not indicate anything.
The indication of PV display is abnormal
or unstable.

The setting value does not change evenor
key is pressed.
if thePresumed cause and solution• Thermocouple or RTD is burnt out.
[Thermocouple]
If the input terminals of the instrument is shorted and if avalue around room temperature is indicated, the instrument islikely to operating normally, however, the sensor may be burnt out.
[RTD]
If approx. 100 of resistance is connected between the input
terminals A-B of the instrument and between B-B is shorted,and if a value around 0 (32 ) is indicated, the instrument islikely to operating normally, however, the sensor may be burnt out.
• The lead wire of thermocouple or RTD is not securely
connected to the instrument terminal.
• Check if polarity of thermocouple or compensating lead wireis correct.
• Check whether codes (A, B, B) of RTD agree with the
instrument terminals.
• The Hold function is working.
• No alarm action is selected during the Alarm type selection.
• Check whether sensor input is correct.
oris correct.
• Check whether temperature unit
• Sensor correction value is unsuitable.
• Specification of the TC or RTD is not correct.
• AC leaks into the TC or RTD circuit.
• There may be equipment that interferes with or makes noise
near the FIR-201-M
Lock 1 or Lock 2 is selected during Set value lock selection.

For all other malfunctions, please contact our main office or dealers.
