Note: 1.Analog output outputs up to approximately 6 V (24 mA). Outputs 1 V (4 mA) when there is no incoming light.
2.F.S. stands for full scale. For a current output, full scale is 16 mA (4 to 20 mA).
Voltage output: 4 V (1 to 5 V)
3.Definition of the luminous energy integral: The physical unit of the luminous energy integral is energy (J: joules) and this value is calculated by multiplying the
UV intensity (mV) by the time of exposure (s), but it is dimensionless when this sensor's analog output value (V) is used for the UV intensity. The integral is
measured with an 11 ms sampling time.

Operation
●F3UV-A30/A03
Sensitivity adjustment method
During initial setup or when UV light source is replaced, adjust
the analog output to 4 to 5 V as follows.
(Sensitivity adjustment)
After installing the sensor, adjust the sensitivity with the sen-
sitivity control.
When the analog output is within the range of 4 to 5 V, the or-
ange operation indicator lamp illuminates. Once it illuminates,
fine adjust the output to the required voltage.
(If the UV light intensity is too high)
If the analog output is 5.0 V or higher when the sensitivity con-
trol is set to MIN (all the way to the left), the UV light intensity
exceeds the sensor specification. Either use the optional F39-
HU1 Exposure Cover, or move the sensor away from the UV
lamp.
(If the UV light intensity is too low)
If the analog output is 5.0 V or lower when the sensitivity con-
trol is set to MAX (all the way to the right), the UV light inten-
sity is lower than the sensor specification. Move the sensor
closer to the UV lamp.
●F3UV-XW11/XW41
Basic Operating Procedures
(1) Install the Amplifier Unit.
(2) Connect the Fiber Unit to the Amplifier Unit.
(3) Turn ON the power supply.
(4) Select an operating mode with the operation mode switch.
(Light intensity monitor mode or light intensity integral
mode)
(5) When using the analog output, select current or voltage
output with the output selection switch.
(6) Set the processing mode switch to TEACH and perform
the teaching operation.
• Light Intensity Monitor Mode
Perform the zero-point setting when the indicator is not
lit and make the sensitivity setting when the indicator is
lit. (Perform the sensitivity setting after the temperature
has stabilized.)
• Light Intensity Integral Mode
Use the start setting at the start of illumination and the
stop setting when completed.
Teaching can be performed by pressing the buttons or
with codes.
(7) When changing the threshold value in light intensity mon-
itor mode, set the processing mode switch to ADJ and ad-
just the threshold value. The judgement output will go ON
if the light intensity is below the threshold value. The
threshold value is set to 50 at the factory.
(8) Set the processing mode switch to RUN to start measure-
ment. In light intensity integral mode, start integration with
the Reset input.
●F3UV-XA
Sensitivity adjustment method
During initial setup or when UV light source is replaced, adjust
the control output to any value between 4 and 5 V using the
sensitivity control. After that, you can monitor weakening of
the UV light source intensity by monitoring the control output
value.
(Sensitivity adjustment)
After installing and securing the sensor, adjust the sensitivity
with the sensitivity control. When the control output value is
within the range of 4 to 5 V, the orange operation indicator
lamp illuminates. (The sensor output goes up to approximate-
ly 6 V, and thus the operation indicator lamp does not illumi-
nate if the sensitivity is too high.) Adjustment is easier if you
verify that the operation indicator lamp is illuminated and then
fine-adjust the sensitivity to the desired value while viewing
the voltmeter display.
(If the UV light intensity is too high)
If the analog output is 5.0 V or higher when the sensitivity con-
trol is set to MIN (all the way to the left), or if the analog output
does not decrease when the sensor is moved away from the
UV lamp, the UV light intensity exceeds the sensor specifica-
tion. Move the sensor further away from the UV lamp
(If the UV light intensity is too low)
If the analog output is 5.0 V or lower when the sensitivity con-
trol is set to MAX (all the way to the right), the UV light inten-
sity is lower than the sensor specification. Move the sensor
closer to the UV lamp.
For detailed operation procedures, see the product manual.

Do not use the system until 1 second has elapsed after turn-
ing on the power and it is in a detection-capable state. If the
F3UV and the unit on which it is installed are connected to
separate power sources, be sure to turn on the F3UV power
first.
During use
Mounting the sensor
Ultraviolet light is harmful. Ensure the UV lamp is off when you
install it.
Sensitivity setting
Temperature drift may cause the analog output value to
change. If the temperature is rising, wait until it has stabilized
sufficiently to set the sensitivity.
Output characteristics
If the analog output is not proportional to the ultraviolet illumi-
nance of another manufacturer's illuminance meter, the fol-
lowing problems are possible.
(1) If the distance between the lamp and the sensor was
changed to adjust the ultraviolet illuminance, the values
sometimes differ due to differing angles of view in the sen-
sor receiver and in the other manufacturer's illuminance
meter receiver.
(2) If the illumination power of the UV lamp was changed to
adjust the ultraviolet illuminance, accurate monitoring may
not be possible due to insufficient stability of the UV lamp.
Wait until the UV lamp has sufficiently stabilized and then
perform the measurement.
(3) If the temperature rises due to the UV lamp, wait until the
sensor temperature stabilizes sufficiently and then per-
form the measurement.
(4) If the sensor and the illuminance meter have different
sized receiver areas, the values sometimes differ due to
uneven illuminance on the receiver surface.
Miscellaneous
Cleaning
Do not use thinners. Use a soft cloth or blower brush to re-
move dust and dirt from the receiver window.
Mounting dimensions
(Installation strength)
Screws for mounting the sensor should be tightened to a
torque of no more than 0.49 Nm.
(Protection against ultraviolet light)
The indicator lamps and cables on the sensor are not protect-
ed against ultraviolet light. If the indicator lamps and cables
will be exposed to ultraviolet light, use the F39-HU2 and F39-
CU1 to protect these parts.
Use protective gear if ultraviolet light will directly enter your
field of vision or shine on your skin while mounting and adjust-
ing the sensor.
Mounting
Mounting procedure
(1) Mounting strength * The torque for tightening screws when
installing the sensor should be no more than 0.49 Nm.
Protection against ultraviolet light
This amplifier is not protected against ultraviolet light.
Do not install the amplifier unit in a location where it will be ex-
posed to ultraviolet light.

Mounting the head unit when using as an ultraviolet power
monitor
When installing the head unit, turn off the ultraviolet light and
install in safe conditions.
The torque for tightening screws on the fiber unit should not ex-
ceed 0.78 Nm.
(F3UV-HM)
(F3UV-HT)
Mounting the fiber unit when using as an illumination monitor
As with a regular fiber unit, attach using a an M4 locking nut.
When connecting to an amplifier unit
(1) Cutting the Fiber (F32-70 only)
Insert the fiber into the hole of the cutting tool and set the
tool at the desired length.
Press down the blade and cut the fiber. Do not stop when
the fiber is only partially cut; make one clean cut
Once a hole has been used to cut a fiber, do not use that
hole again. The cut surface may not be clean enough
and the detection characteristics may be degraded.
(2) Installing the Fiber
With the lock button in the release position, insert the fiber into
the Unit and press the button until you hear a click. This click
is the sound of the fiber being locked.
(3) Fiber removal
Press the lock button again. The lock will be released, the
lock button will pop up, and it will be possible to remove the
fiber.
Do not force the lock button up by pulling on it. (To main-
tain the fiber's characteristics, check whether the lock is
out of place.)
(4) Fiber Insertion Location
When inserting the Fiber Unit into the Amplifier Unit, al-
ways insert the Fiber Unit completely as shown in the fol-
lowing diagram.
(5) Fiber Unit Installation/Removal Precautions
Install and remove the Fiber Unit only when the ambient
temperature is between -40 and 40°C.
(6) Protecting the Fiber Unit
If the outer sheathing of a FIber Unit other than the F32-
300 is exposed to UV light, protect the fiber by covering it
with the F39-FU1M Protective Tube.
Fiber Unit/Base Unit
The quality of the connection between the Fiber Unit and
Amplifier Unit has a major impact on the operating charac-
teristics, so be sure to connect these Units securely.
