The ambient temperature and pressure under which these devices are used
are set separately.

Take care that unclear liquid may not be sensed stably.
Take care that the tube may stretch by maximum 2% of the total length if it is used
at a high temperature.
Bending radius of the fiber cable must be R15mm or more (tube: R40mm or
more). However, do not bend 26mm length from the tip.
If the bending radius is smaller than the specified value, the sensing performance
may deteriorate.
Do not use the fiber at places having intense vibrations, as this can cause mal-
function.
Keep the fiber head surface intact. If it is scratched or spoiled, the detectability will
deteriorate.
Ensure that any strong extraneous light is not incident on the receiving face of the
fiber head.
Do not apply excessive tensile force to the fiber cable.
Take care that the sensor is not directly exposed to fluorescent light from a rapid-
starter lamp or a high frequency lighting device, as it may affect the sensing per-
formance.
SENSITIVITY SETTING

Do not move or bend the fiber cable after the sensitivity setting. Detection may
become unstable.
Thank you very much for using SUNX products. Please read this Instruction Manual

Adjust the sensitivity, observing the op-

However, since the condition for lighting
up of the indicator depends on the com-
bination of the sensing condition and
selected operation for L/D-ON, verify it
from the table on the right.
The sensitivity adjuster is a 12-turn po-
tentiometer. The maximum sensitivity is
obtained by turning it fully clockwise.

٨This product incorporates an 'assist function', which helps to easily search the
optimum sensitivity position by blinking of the pointer.
In order to make 'assist function' effective, switch the operation selection switch in the
order L-ON (not immersed ON) ψD-ON (immersed ON) ψL-ON (not immersed ON).
<Assist function>
Notes: 1)
2)
'Assist function' turns off automatically once the sensitivity adjustment has
been completed.
In case 'assist function' is not to be used, set the operation selection switch
to D-ON (immersed ON) and wait for 2 sec., or more, to make 'assist
function' ineffective.

If the jog switch is pressed continuously 3 sec., or more, full auto-teaching is done. In
case of FD-F8Y, correct threshold value setting cannot be done in full auto-teaching.
If the mode selection switch is changed to 'RUN' when ' ' is being displayed
on the LCD display, the incident light intensity taught at Step Ԝis not recorded.
When the mode selection switch is changed from 'SET' to 'RUN' or from
'MODE' to 'RUN', the set threshold value or the contents of each mode set-
ting are stored in an EEPROM. However, since the EEPROM has a lifetime,
the threshold value setting cannot be done for more than 100,000 times.

When 'assist function' is not used, the pointer does not blink.
When 'assist function' is not used, the middle point of and is regarded
as the optimum sensitivity point.
In order to protect the mechanism, the sensitivity adjuster idles when over
turned, which may result in a backlash of 1 to 2 divisions.
Depending upon the sensing conditions, stable sensing may be possible at a
position which is slightly shifted from the optimum sensitivity point.

In the fiber not immersed condition, slowly

In the fiber immersed condition, slowly turn

goes into the ON state again. Once it is
switched on, turn the adjuster counterclock-
wise a little and find the point where it is
switched OFF. The pointer blinks twice at the

If the sensor does not go into the ON state,
MAX is the point .
Turn the adjuster towards the point from
the point slowly. The pointer starts blinking
when it approaches the optimum sensitivity
point and blinks faster at the optimum sensi-
tivity point for 3 sec. This point is the optimum
sensitivity point. (Note 2)

If the jog switch is pressed continuously 3 sec., or more, full auto-teaching is done.
In case of FD-F8Y, correct sensitivity setting cannot be done in full auto-teaching.
Also, if the mode selection switch is changed to 'RUN' while level indicators '4'
and '5' are blinking, the incident light intensity taught at Step Ԛis not recorded.
When the mode selection switch is set to 'SET' or 'MODE', the sensor is more
susceptible to extraneous light. Hence, when sensing a liquid, ensure to set the
mode selection switch to 'RUN'.
When the mode selection switch is changed from 'SET' to 'RUN' or from
'MODE' to 'RUN', the set sensitivity or the contents of each mode setting are
stored in an EEPROM. However, since the EEPROM has a lifetime, the sen-
sitivity setting cannot be done for more than 100,000 times.

Also, if the mode selection switch is changed to 'RUN' while level indicators

When the mode selection switch is set to 'SET' or 'MODE', the sensor is

When the mode selection switch is changed from 'SET' to 'RUN' or from
