The response time is the rise time or fall time of the output signal to 10 to 90%.

2. The

ambient operating illumination is the illumination that changes the analog output +5% F

.S. at 200 lx; it is not the operational limit.

3. An

analog output of up to 6 V (or 24 mA) can be output. The output is 1 V (or 4 mA) when there is no incident UV light.

4. F

.S. stands for full scale. For a current output, full scale is 16 mA (4 to 20 mA). For a voltage output, full scale is 4 V (1 to 5 V).

5. 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 1

1 ms sampling time.

Precautions

Be

sure to observe the precautions listed here. These precautions

are

essential for safe operation.

• Do

not

use these Units in locations with flammable or explosive

gases.

• Do

not use these Units in water

.

• Do not attempt to disassemble, repair, or improve these

products.

• Always use a power supply voltage that is within the specified

operating

range. Do not use with an AC power supply

.

• Be sure that wiring is correct, such as the polarity of the power

supply leads.

•

Connect loads properly

.

•

Do not short-circuit the load’

s terminals.

• Do not mount the Amplifier Unit in a location where it will be

exposed

to UV light.

Precautions Common to the F3UV-series

Wiring

Connections

Make

sure that the power supply voltage is below the maximum volt

-

age

before turning the power ON.
Be sure that the terminal polarity and wiring are correct.
Never

share a conduit that is used for high-voltage or power lines.

Use extension cords with a minimum thickness of 0.3 mm2, less
than

5 m long, and check operation before using.

Power Supply

When using a commercial switching regulator, ground the FG
(frame

ground) and G

(ground) terminals. Output signal noise will be

excessive

if the power supply is not grounded.

After

turning on the power supply

, wait for at least one second

until

consistent

detections can be performed before using the Monitor

. If

separate

power supplies are used for

the F3UV and connected de

-

vices,

always turn ON the F3UV’

s power supply first.

Installation and Operation

Installation

UV

light is harmful, so be sure to turn OFF the UV light source before

installing

the F3UV

.

Sensitivity Setting

The

analog output value will change due to temperature drift. If the
temperature is rising, wait for the temperature to stabilize before
setting the sensitivity.

Precautions for the F3UV-A30/A03

Installation

Installation Torque

T

orque the sensor’s Main Unit screws to 0.49 N-m max.

Precautions Regarding UV Light

The

sensor’s display and

cord are not protected against UV expo

-

sure.

If these parts will be exposed to UV light, protect

them with the

F39-HU2

Protective Cover and F39-CU1M Protective T

ube.

When

UV light will be in the

user’s field of vision or directly contact

the

skin during adjustment, use a shield or other protective device

to

prevent

injury

.

Adjustment

Sensitivity Adjustment

Use

the following procedure to adjust the analog output to 5 V before

initial

operation or after replacing the UV light source.

1. Set up the Sensor and the UV light source to be monitored.
The sensitivity adjuster is factory set to its minimum setting
(all

the way to the left).

2. T

urn ON the UV light source.

3. Check

whether the operation indicator (orange) of the Sensor
is lit. The operation indicator will light if the analog output
value is between 4 and 5 V. If it does not light, adjust in the
following way.

4.

Rough Adjustment
The

operation indicator will light if the analog output value is

between

4 and

5 V

. In this case, proceed to

Fine Adjustment

below. If the operation indicator is not lit, check whether the
operation indicator can be made to light by turning the
sensitivity adjuster. If the operation indicator still does not
light, then the UV intensity is either too high (i.e., exceeds
Sensor specifications, with an analog output value greater
than

5 V), or is too low

. If the UV intensity is too high, make the

operation

indicator light by

either using the F39-HU1 Filtering
Cover (sold separately), or moving the Sensor farther away
from

the UV light source. If the UV intensity is too low

, move
the Sensor closer to the UV light source, until the operation
indicator

lights.

5.

Fine Adjustment
Adjust

the sensitivity adjuster until the analog output value is

5 V. If it not possible to obtain a value of 5 V this way

, then the
distance between the Sensor and the UV light source is
inappropriate. Move the Sensor either closer to, or farther
away

from the UV light source.

Cleaning

Never

use paint thinner or mineral spirits of any kind. If there is de

-

bris

or dust on the light-receiving window

, wipe it of

locations where it will be exposed to UV light.

Adjustment

Basic

Operating Procedures

1.

Install the Amplifier Unit.

2.

Connect the Fiber Unit to the Amplifier Unit.

3. T

urn 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
Make

the zero-point setting

when the indicator is not lit and

make

the sensitivity setting when the indicator is lit. (Make

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 monitor

mode,

set the processing mode switch to ADJ and adjust the
threshold value. The judgement output will go ON when 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
measurement. In light intensity integral mode, start
integration

with the Reset input.

Cleaning

Never use paint thinner or mineral spirits of any kind.

Installing the Fiber Unit and Amplifier Unit

The

quality of the connection between the Fiber Unit and Amplifier

Unit

has a major impact on the operating characteristics, so be sure

to connect these Units securely.

Securing the Fiber 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 on 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.

Removing the Fiber
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. (T

o maintain
the fiber’s characteristics, check whether the lock is out of
place.)
