Unclear liquid may not be sensed stably.
1,000mm from the amplifier insertion end is the cutting range.
Liquid being detected should also be kept within the rated ambient
temperature range.
The ambient temperature and pressure under which these devices are used
are set separately.
For usage with both of these at or near the maximum permissible value,
please contact our office.

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
5
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
carefully and thoroughly for the correct and optimum use of this product. Kindly keep
this manual in a convenient place for quick reference.

The fiber cables should be cut off at the ends with the fiber cutter

(accessory) before insertion into the fiber amplifier.
For the usage of the fiber cutter (

), refer to the instruction manual
enclosed with this product other than this instruction manual.
Do not scratch the fiber sheath while cutting the fluorine resin tube.

This is the method of setting the threshold value by teaching only the water absent

Adjust the sensitivity, observing the op-
eration indicator (orange).
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.
The pointer shows the present sensitivity level.

This is the method of setting the threshold value by teaching two levels,
corresponding to the immersed and not immersed conditions. Normally, setting is
done by this method.
